Many years ago when I was 17 and my sister Kim was 15 we had a very eventful two weeks over the summer. It was after July 4th and the weather was very hot. Our air conditioning wasn't working and all we had was overhead fans. Even then it was very hot so I was wearing just my shorts and t-shirt at night most of the time. My sister would wear loose fitting nightgowns. She usually was not wearing a bra and it was getting my attention when she walked around. She really filled out so it was hard not to look at her. In the kitchen she would bend over at the refrigerator and I was occasionally get glimpses of her nice beautiful breasts and nipples. One time I swear she caught me looking and it made me red faced. The second time it happened I was thinking maybe she did it on purpose. I was also able to tell she wasn't wearing any panties most of the time which would also drive me crazy. Me catching glimpses of her tits and trying to figure out if she was wearing panties is how our crazy couple of weeks began this one hot July.

So late one night, we were in the downstairs TV room watching TV together. Our parents worked in the city and they would get up very early to go to work. Since there was no school my sister and I would stay up to 3 am practically every night and then sleep until noon. One night after our parents had long gone to bed, as Kim was flipping through the channels. She landed on one of the premium movie channels. The movie was showing a young couple starting to have sex. I could not believe she stopped on this channel. At first it felt a little of uncomfortable to be watching soft porn with my little sister. But I soon forgot about that as the scene started showing tits. After a few minutes I glanced over at my sister. Our couch was L-shaped and I was on one end of the L and she was on the other to my right. The TV was on my left. So when I glanced right I could see her hand resting on her private area.

Her hand was on the outside of her nightgown and she was rubbing her pussy up and down with her pressing fingers tips. I was already slightly aroused from watching the sex scene in the movie but watching her rubbing herself made me rock hard. I felt flush and my ears were burning hot. I was wearing loose fitting gym shorts. I had raging hard-on which was clearly visible from the outside of my shorts. I was so mesmerized thinking about what my sister was doing I didn't notice I had a raging hard-on. I looked back at her and realized she was looking right at crotch. My soft cotton gym shorts were very revealing. I was feeling a little embarrassed so I got up quickly and went upstairs to the kitchen. It took me a while to calm down. I actually went to my room and got underwear because I did not feel safe wearing just my shorts. When I made it back down to the TV room my sister was sitting up and watching something else. I didn't know what to think about what just happened.

The next night we were watching TV again. This time I was wearing underwear because I was afraid I would show off too much in front of her. She was wearing a different nightgown. This one had buttons all the way down the front. She had it unbutton almost all the way down to her belly button. She was sitting slightly sideways so the top was flapped over and I could practically see one of her breasts in full view. She had to know she was exposing herself to me. Again as she was flipping channels and she stopped on a chick-flick type movie. I did not complain because I was hoping there would be another sex scene. After about 20 minutes we got to a sex scene. Again, between the tits on TV and glimpses of my sisters partially exposed live tit, my cock got hard and visible in my shorts. But this time my underwear made me feel a little less exposed.

Again, I would occasionally look over and see her rubbing herself. Except this time I think she knew I was watching. She was rubbing herself pretty hard and it was very arousing to watch. I could not help myself but occasionally I would catch myself with my own hand rubbing the outside of my shorts. She had to be watching me do this too. The idea of her watching me rub myself made me even more excited. I wasn't sure what to think or where this was going.

The sex scene was over for a while and I was started to get a little bored. I kept looking over to my right to see what she was doing but nothing was going on. Then she got up and went over towards me. She then leaned over in front of me and picked up her drinking glass off the coffee table. As she did this she tilted her head as if she was watching the movie. Her nightgown dropped down and I could see both her breasts in full view. They were so close! She just stood there for what seemed like a very long time. I think she might have been waiting and watching me to see if I would get erect. I was rock hard again with arousal right in front of her. After a while she went upstairs and went to the kitchen.

I was just calming down when she came back. But instead of going over to the couch she went to the downstairs bathroom which was behind me and to my left. She goes in there and sits down leaving the door wide open. I could see her on the toilet sitting down. She pulled up her nightgown and I could see the naked side of her one leg up to her waist. She must have known I was watching her pee. I could hear her peeing. She got up, washed her hands and came back to the couch.

I never saw a girl pee before so it was very interesting to watch. I knew she wanted me to watch her. So I thought two can play this game. I would do the same for her and give her a show. She was sitting to my right on the sofa but she had a clear line of sight into the downstairs bathroom. As I thought about going in there to pee in front of her I was getting aroused. I get up and walk over to the bathroom. I leave the door wide open and pull down my shorts. But my cock is semi-erect so in order to pee I had to lean forward to aim into the toilet. But there was no doubt in my mind my sister had full view of my cock peeing which made it even harder for me to pee. I washed my hands and came back to sit down.

This time my sister was sitting with her legs facing me with one leg propped up on pillow. Her nightgown was pulled up above her knees so I could see her pussy area right in front of me in the light. Looking at her pussy right there gave me a thrill bump in my stomach. I was starting to get a pretty hard erection. The underwear I had was pretty tight and I was getting braver by everything we were doing. I told her I would be right back and I told her to find something good to watch on TV. I went up stairs and I got some really loose fitting shorts with a draw string. I didn't have any underwear on and these shorts would really show me off being erect. I went back downstairs and sat down on my side of the sofa. My sister already found some kind of soft porn movie on with girls running a car wash. Eventually there was a pretty heavy duty sex scene. I pulled the draw string on my shorts making them very loose and untied. Her legs were still facing me with her pussy on display. As the scene progressed I could feel my erection pressing up on my shorts. It was very obvious and in her full view that I had a huge erection. She began rubbing herself except this time she pulled her nightgown way up and her hand was directly on her pussy. Again, I was very aroused and rock hard watching her do this.

So I started gently rubbing myself in front of her. I was running the tips of my fingers up and down the front of my shorts. The tip of my cock began to come out of my shorts. I could tell she noticed my cock peeking out because she started rubbing herself a little more vigorously. I pull my shorts down slowly and now she could see my full raging cock in all its glory. I grabbed my cock with my left hand and began slowly jerking it up and down in front of her. I heard her give out a slight moan and out of the corner of my eye I noticed her body getting really tense. She arched her back a bit and then she relaxed. She continued to watch me as I stroked my rock hard cock.

After a few minutes she got up leaned over me and said, "I will be right back." She turned her head closer towards my cock and stared right at it as she moved away from me. Her watching me jerking off so intently with her face only inches away from my cock made me so freaking hard. I was so ready to come I just got up and went into the bathroom, closed the door, and shot my load so hard I had to clean it off the mirror. When I came out she was back on the sofa she didn't look at me but just kept watching the TV. She had to know what I had just done. It was really late and we both were very tired so we just went to bed after that.

The next night started in the kitchen. I was wearing my same shorts. She was wearing another nightgown but this one was pretty much see-through and no bra. As I was getting some pretzels she turned and brushed her breast against my arm. She just kept doing her thing as if nothing happened but I thought she definitely wanted me to feel her breast brush across my arm. Her breasts were soft but perky. I felt her erect nipples go across my arm. I started to become slightly erect. My erection only got worse as I thought about her looking at me being erect in my shorts. She was bent over looking in the refrigerator and as I began to turn I pressed my erect cock across the back of her shorts. She had to feel my cock brush up against her. I was fully erect now with a rock hard erection. I could feel cold wet drops of pre-cum in my shorts as I walked down the stairs to the TV room.

Again, my sister found a movie with a sex scene. We continued to rub ourselves in front of each other. And we continued to watch each other doing it. After while she got up and said she was going to get more pretzels. There were few left in the bowl. As she walked right in front of me she knocked the bowl off the coffee table as she reached for it. A few pretzels went on the floor. She pulled up on her nightgown as she bent over to pick up the spilled pretzels. Her butt was 10 inches from my face completely naked and in full view of my face. She picked up the spilled pretzels and put them back into the bowl. I thought she contrived the whole thing so she could show off to me. I could see her perfectly tight round ass inches away. I could see her pussy lips in every detail. After a long minute she straightened up and went into the kitchen. My cock was raging so hard it actually was hurting. She came back and sat again on her side of the sofa.

I knew it was my turn so I had to think of something to do. So I stood up with my raging hard on and took a step toward her. I put my arms up and pretended to yawn. My shorts were really loose and I wiggled my hips so my shorts would drop. I was completely naked from the waist down in front of her. I pushed my hips out so my raging cock was practically in her face. I stayed there for good 20 seconds stretching so she could get a good long look at what she was doing to me. I then sat next to her on her side of the sofa with my shorts around my ankles and my cock fully exposed and erect.

After a while she moved closer to me and laid her head on my chest. Her face was only a few inches away from the tip of my cock! The movie continued but I don't think we were paying much attention to it. She pulled her nightgown up and stared rubbing her pussy right in front of me. Her face being just inches away from the tip of my cock and it was driving me crazy. And watching her rub and finger herself did not help either. I wanted her to wrap her lips around my cock so bad. And thinking about it made my erection even harder. This went on for some time but she did nothing more. I could not take it anymore so I got up and told her I would be right back.

So I went into the bathroom and left the door open. I knew she was watching. I started jerking myself off. I would spit into my palm so my hand was warm and wet. I was thinking about her warm pussy as I rubbed myself in front of her. Knowing she was watching me made me so rock hard. Again I climaxed and it went everywhere. Some of my cum went on the mirror again. She came over to the bathroom and said she would help me clean it up. She grabbed some tissues actually touched my still semi-erect cock as she reached for them. I just stood there and watched her clean up the cum off the mirror and sink in front of me. She then grabbed some more tissues and then said, "you need to be cleaned me off too." She grabbed my cock which instantly became harder and started cleaning off the cum. She then squeezed it up to the end to draw out the last bit of cum which she wiped off with the tissues. I never had any girl touch my cock before! It was very exciting to me. After we left the bathroom we both went to bed.

The weekend had arrived. Nothing happened the next night because she was sleeping over her girlfriend's house. The next day I got completely involved playing video a game with my friends all day and all night. Sunday she stayed in her room all night. For two days now there must have been a thousand times I thought about Kim handling my cock. By Monday night I could not think about anything else.

It's now Monday night and our parents went to bed early as usual. I was watching TV wearing a t-shirt and soft cotton gym shorts with no underwear. My sister comes down just wearing a button down night shirt and panties. As usual she did not have a bra. As she came down the stairs I could not stop staring at her boobs as they bounced along. She smiled and sat in her spot. I gave her the remote and told her to find something fun to watch with a devilish tone. She started flipping through the channels. She found another chick flick and we started watching. She beckoned me to sit by her so I shifted over. She started laying her head on my chest again. As we are watching another sex scene comes up on in the movie. She continued to rub herself in front of me this time slipping her hand down her shorts which was fun to watch.

And then she started to unbutton her blouse. I kept pretending to watch the movie but I could not help but keep the corner of my eye on her as she unbuttoning her blouse. Soon all the buttons were undone. She rolled over a bit with the back of her head on my lap. And in doing so the blouse fell to the sides and I could see both her breasts in full view. Erection tightness set at maximum. I draped my arm over her as I pretended to watch the movie. She wiggled a bit and put her hand on my hand. I could not stop looking at her breasts. She then grabbed my hand and placed it over one of her breasts. I began to lightly massage her boob. It was very exciting. This is something I've been thinking about doing for a very long time. She gave out little moans of delight as I was massaging her boobs. I could feel her erect nipples pressing against the palm of my hand as I rubbed her. Her skin was so amazing soft and nice.

She then grabbed her panties and then pulled them off. She was naked from the waist down. I could see her pussy within the reach of my hand! She started rubbing and fingering herself. I took my other hand and push my shorts down over my knees. I started stroking my cock with my left hand with my right hand still massaging her boobs. She turned her head slightly to watch me jerking my cock. I could not believe I was jerking my cock off right in front of her face! She just stayed there watching me and kept rubbing her pussy. Her mouth was so close to the tip of my cock it was making my stomach flutter with excitement!

She then put out her tongue and leaned a little closer. I rubbed the tip of my cock over her tongue. She was really excited by this and was rubbing herself even faster. She leaned a little further and put her mouth completely over my cock and started sucking on it. She was sucking on it really hard. I started rubbing her bare butt as she was sucking on me. She kept masturbating herself with one of her hands. I think she orgasmed at one point because her body tensed up like before. She then kept sucking on me so hard. I could not contain myself any longer and blasted a huge load of cum into her mouth. Her head jerked back at first. But then she eagerly swallowed it and kept sucking. I could not think about anything else but her sucking me as I cummed into her mouth. It felt like for a brief moment time just stopped. I could feel her swallowing my cum down her throat after it came out of my cock. It felt so amazingly good. Even as my cock started to go limp she continued to suck on my cock tightly until she swallowed every single drop of cum from my body. I thought afterwards, "wow, my sister really likes to eat cum."

At this point I thought we were done but then she took her fingers out of her pussy and while looking at me in the eye she started sucking on her own fingers. She licked and sucked her fingers again and again. She would dip them back into her pussy and repeated sucking on them several more times. She then dipped them and shoved her fingers up near my mouth. I have never licked a pussy before so it was a little weird at first. There definitely was a strong smell and it kind of excited me. I started licking and sucking on her fingers just like she was doing. As I sucked and licked her fingers and kept eye contact with her like she was doing with me. This was the first time I had ever tasted pussy before. And I started to get slightly erect again. My sister seeing this eagerly went down on me again and started sucking on my semi-erect penis. It felt really good but I was not able to cum again. She continued to suck on me for what seemed like forever. She must have had been sucking on my semi-erect penis in her mouth for 10 minutes straight! It was getting really late and I went limp because I was so tired. She popped her head up and kissed me on my cheek. We then both went upstairs to go to bed.

The next night is when things really got interesting. My father left early that morning on business trip to the west coast. That night, as my mother is getting ready for bed she leaves her door open. As I walk by her room I see her there brushing her hair completely naked in front of the mirror. I can see her butt from behind and her tits and pussy in the mirror. Her breasts were bigger than my sisters. I just was looking for just a few seconds from the hallway when my sister comes out of her bedroom. She presses her hand up against my semi-erect cock leans forward and whispers into my ear, "like what you see?" She then proceeds past me into my mother's room and closes the door. My sister teasing me by pressing her hand to my cock and whispering into my ear was very effective in getting me aroused. I couldn't stop thinking about what she just did. I ended up downstairs watching TV with an erection the whole time and she wasn't even in the room!

My sister comes down wearing an insanely see-through night shirt and no panties. She was naked from the waist down! She leans over me and practically shoves her breasts in my face and takes the remote out of my hand. I was in no position to give her an argument. She navigated to the rentals page on the TV and click on a movie that had already had been rented. She clicked on play from start. It was some porno movie but with some really heavy duty sex scenes. I was excited by it and before long I start rubbing my cock in the open for my sister to watch again. And she was fingering her pussy and licking her fingers for me to watch. As we are watching the porn it occurred to me the audio was too loud so I said, "lower the volume you don't want mother to hear it." She replied with, "don't worry, I don't think she will mind at all." Her comment made my head spin. What did she mean by she would not mind at all?

So I just continue rubbing myself watching the movie and my sister. My cock is in full view. My sister gets a text on her phone and almost instantly clicks out a response. I didn't think much of it since she's always on her phone. A few moments later I see my mother at the entrance to TV room. She's wearing a robe that is untied and mostly open. I can see her breasts and pussy. She's looking at me masturbating. I stop and feel a little panic and cover myself up. She walks over to my sister on the sofa. My sister now has her legs spread open with her knees bent on the sofa. My mother takes off her robe, kneels down before my sister and starts licking her pussy. My sister is moaning with delight as my mother is tonguing her this way and that. As I'm watching my naked mother licking my sister's pussy my erection is rock hard and hurting again. She turns her head looks at me and says, "Sit over here I want to watch you masturbate while I lick your sister's pussy." I wasn't completely comfortable with this but it was very hard to say no.

I leave my shorts on the floor and move to the same side of the sofa next to my sister for my mother to watch me masturbate in front of her. I'm watching her watch me. I can see she's excited by my handling of my own cock in front of her. I bend it towards her so it's straight up so she can see how long it is. She reaches out and starts stroking my cock. She then leans forward and starts sucking on my cock while she's rotating her hand stroking it down vigorously. I was so close to blowing my load right at that moment. She then turns back to my sister and starts licking her even more furiously than before. I can see my sister tense up and orgasm. There was no doubt she orgasm this time because she let out a pretty loud moan as she arched her back.

My mother sits up and I can see her breasts in full view for the first time. My sister then slides down the sofa a little more on her back and she pulls her legs way back. I can see her butt hole clearly below her pussy. My mother then leans forward and starts licking my sister's butthole right in front of me! I can't believe what I am seeing in front of my eyes. I'm very close to blowing another huge load. I can't take much more of this! My mother is driving her tongue in and out of my sister's butthole. I can see my mother pressing her face forward to drive her tongue deep in to my sister's butthole and then curling it upward as she pulls away. By the expression on my sister's face and her moaning she obviously was enjoying it very much.

I'm seconds away from releasing my load of cum. My mother turns to me and says, "Stand up and cum over her your sister's butthole while I'm licking it." With urgency and without questioning I stand up and start stroking my cock towards my mother's face. Her tongue is deep into my sister's butthole as I blow my load all over my mother's face and all over my sister's butt. Cum is dripping everywhere and my mother starts eagerly licking and eating it all up. My sister's butt area is completely clean but there's still a lot of cum on my mother's face.

My sister sits up and grabs my mother's face and starts licking and eating my cum off of it. My mother grabs my semi-erect cock and squeezes out remaining cum into her open mouth. My mother turns to my sister and starts French kissing her with my cum in her mouth! I had the distinct impression this was not the first time they both shared a cum full kiss before. Afterwards my mother sits on the sofa and spreads her legs. My sister kneels down before her and starts licking my mother's pussy until she orgasms. I watch the whole time as my mother is holding my semi-erect penis in her hand. My mother is squeezing my penis harder and harder as she is getting closer to orgasm. After my mother cums she announces she has to shower and go to bed because she has to get up early for work. She leaves but my sister and I remain in the TV room. We are next to each other still both naked from the waist down watching TV. We are both occasionally playing with ourselves but nothing more happened that night. After about an hour we head off to bed.

The next night my mother says she's going to bed early because she says she's so tired. I'm wearing my loose fitting shorts with the draw string again and no underwear. What's the point after what happened the previous night. As I walk by my mother's room she calls me in. Again she's wearing her robe untied and open. I'm sitting on the bed watching watching her get her work cloths out for the next day. I can see parts of her naked body as she walks around the room. I am slightly aroused by seeing glimpses of her naked body. She stops in front of me with the robe open and leans over and kisses me on the head. Her breasts are practically in my face. She says to me, "On your way out tell your sister to come in here to say goodnight. We have something special planned for you for tomorrow night." I smile and agree to get my sister as I walk out.

It's still the same night. My mother went to bed. I'm downstairs watching TV. This time I decide to lie on my stomach as I watch TV in front of where my sister usually sits. She comes down wearing her normal nightgown with no bra and no panties. She sits on the sofa behind me. I turn and give her the controller as usual. I can see her pussy lips right in front of me because she has no panties on. She smiles and starts flipping through the channels. We watch something for awhile. She then puts on some kind of soft porn movie. I'm starting to get excited and start moving my hips forward and back because it feels good on my cock. My sister is watching this of course. I feel her foot rubbing my butt. I didn't think anything of it at first but then she tried to shove her big toe into my butthole. I twisted around and say quit it. Then with a wicked smile she says, "You'll be begging me to touch your butt before long." She then slides down to the floor and starts massaging my butt. It feels pretty good I thought. She leans forward and asks me, "Can I slide your pants off." Of course I say yes. It was feeling really good what she was doing.

After getting my pants off she starts rubbing my bare skin butt. It feels even better her rubbing my bare skin. She's working her hands around and using her thumbs to dig a little closer to my butthole. She then spreads my butt cheeks apart and I feel her tongue touch my butthole. It was extremely erotic. She starts licking and probing my butthole the way my mother was doing it to her the night before. She occasionally pauses after licking my butthole to blow cool air on it. It feels really good. I have a rock hard erection. Several times she licks my butthole and then blows cold air on it afterwards. After a really long time of doing this she tells me to roll over. She climbs over me and flips around so her pussy is near my face. She starts sucking on my cock as she lowers her pussy near my mouth. I really like the way she smelled. I started licking her pussy and working my tongue around. My sister was moaning and sucking me harder as I did this. It occurred to me my sister was the perfect size for sitting on my chest this way. She fit perfectly where I was able to easily lick her pussy and she was able to suck on my cock.

After while she gets off me and tells me to sit up. She asks me, "Have you ever tasted cum before?" I say I've tasted my pre-come with my finger. She smiles and says, "Just do what I ask you to do". She positions me so my back is against the sofa upside down with my legs folded over. I'm staring up at my own cock. She spits on her hand and starts stroking cock. She says, "When you cum I want you to keep your mouth open and swallow every drop." She then starts licking my butthole again and blowing on it. While she's licking my butthole she's stroking my cock down towards my mouth. It was just too much for me to take and I blow my own load straight into my own mouth without thinking about it. It tasted pasty salty and weird. It wasn't too bad but still weird to me. My sister then pulls my legs back and squeezes out the last bit of cum from my cock into her mouth. She then turns to me and French kisses me with cum on her tongue. It was all pretty weird at first but I found it to be very exciting. While she's kissing me my sister fingers her own pussy until she orgasms. She takes her wet fingers out and makes me suck on her pussy juices. We French kiss again and then go upstairs to bed.

The next night started earlier. After dinner I'm in my room on my computer looking at porn. My sister knocks on the door and I yell out, "just one second." I close the browser and tell her to come in. She's completely naked and says, "Mother wants to see you now." My sister has a very nice body. It's really fun to look at. As we are walking to my mother's room I can't take my eyes off her naked butt and I have a raging hard-on in my pants. We walk into my mother's room and my sister announces, "Here he is". There is a quilt on the floor and my mother is on it naked and on all fours with her butt up in the air. My mother tells me to sit on the bed and watch. My sister goes over to my mother and picks up a pretty large dildo. She starts licking my mother's ass. She wets the end of the dildo by sucking on it and spitting on it. She then tries to insert the dildo into my mother's butthole. It did not want to go in at first but my sister expertly worked it in with a little more spit. Soon my sister is driving the dildo in and out of my mother's butthole. My mother is moaning with pleasure. I've never seen anything like this before so I can't help but rub my rock hard erection. I pull my shorts off and now I'm standing in front of them and they are watching me. So I spit on my palm and start stoking my cock as I face them. They both seem excited by this and my mother looks up and says, "Don't cum yet. Do what you sister tells you to do."

My sister beckons me to come over to her and she pulls the dildo out of mother's butthole. She pushes me into position and takes my cock and puts it into my mother's butthole. My sister is pressing me in and out with her hands on my hips from behind. It feels really good. I've never fucked anyone before let alone like this. It was crazy exciting. It did not take very long and I exploded my cum into my mother's butthole. As I withdrew my sister grabbed my cock and starting licking and sucking on it. She then went down on my mother's asshole and started licking the cum around and out of her butthole. After a while my sister flips around on her back facing up and my mother gets up and starts squatting over my sister face. My sister keeps licking my mother's butthole as more cum is dripping out. My mother then tells me to come closer in front of her. I did so and my mother started sucking on my cock getting the last few amounts of cum out while my sister is still licking and eating the cum out of her ass. After a few minutes my mother turns around and starts French kissing my sister. After a few minutes of kissing they both went over to the bed and laid on it.

They both beckoned me to come over. My sister told me to start licking her pussy. It was very exciting to lick her. My mother then tells me to lick her pussy so I switch. After I switch my sister is masturbating herself as she watching me. When I switch back she's licking her fingers. My mother then starts masturbating herself watching me lick my sister's pussy. Back and forth I go each time they are licking their fingers. My sister tenses up and orgasms. My mother is vigorously rubbing her pussy. My sister shoves her fingers into my mother's mouth and she starts sucking on them. My mother is very close to orgasm. My sister then gets up on the bed and straddles my mother's face. I tell by the way she was position my mother was tonguing my sisters asshole. My mother pulls her legs up like sister did the night before. So I decided to start licking my mother's asshole. It was little weird at first but I could not help myself. I had no control I just did whatever they were doing. My mother is furiously rubbing her pussy and then gets really tense, moans, and relaxes. My sister falls to the side and as I stand up I ask, "anything else?" They both smile as I leave to go back to my room to play on my computer.

The next night nothing happened. I felt like I needed the night off anyway. I just couldn't believe how crazy my sister and mother were into sex. I had the feeling something was going on for some time but I could not imagine it was like this. The weekend came and my father was back from his business trip. Saturday night my sister had her girlfriend, Lisa, staying overnight. Lisa was just as pretty and perky as my sister. Maybe not as pretty but she was still very cute.

My parents went out to dinner or something. I was in the TV room watching TV. I knew Kim and Lisa were up to something because they were scampering around the house whispering and giggling to each other. From the kitchen my sister yells down, "come up stairs we are in the living room." I had a feeling this was going to happen. I went up stairs and went into the living room.

In the center of the living room was giant cardboard box that was from our new refrigerator we just got. The box was broken down in our garage. The girls must have brought the box in from the garage folded back up again. On the side of box facing me about waist high there was a fist size hole the girls must have cut out. A foot above the hole was a rectangular flap cut into the box about chest high. I see a hand come through the fist hole and my sister says, "Come over here." When I lifted the flap I see my sister's boobs pressing out. I hear the girls giggle out, "suck on these". I was instantly erect as I started sucking on my sister's nipples. There was lots more giggling and she pulled away. And then I hear the girls say, "Try again". This time Lisa's tits were popping through. I kissed and sucked on her nipples. This made me incredibly rock hard. I took off my pants and starting stroking my cock as I sucked on her tits. I was hearing lots of moaning coming from inside.

I then hear them tell me, "Stick your dick through the hole." How could I resist? I stick my dick into the hole and warm lips eagerly wrap around my cock. Both girls must have been taking turns sometimes both at the same time. The idea that Lisa was sucking my cock made me very excited. I could not contain myself any longer and shot a huge load into the box. I don't know exactly where my load went but I felt both girls licking kissing me like crazy. I heard more moaning coming from inside the box. I think they were kissing each other but I wasn't sure as my face was pressed against the cardboard box. They told me to go away so I went back downstairs to watch TV again. After a while I heard them putting the box back in the garage. Nothing else spectacular happened that night.

After that weekend things were not so crazy. My sister gave me a blowjob practically every night for the rest of the summer. My sister really likes eating cum. She would swallow every drop no matter what. When school started after a couple of weeks she had a new boyfriend. Once she had a boyfriend our night time rendezvous came to an end.

My mother really did not pay too much attention to me either. Except on nights when my father was away on a business trip. She would then walk around the house with an untied bathrobe showing off her tits and pussy. It was very exciting to look at her walking around. I would always get an erection. She would eventually bait me into her room. She would sometimes make me lay on her bed face down. She would then come up from behind, spread my butt cheeks, and lick out my butt hole. She would then tell me to roll over and she would suck me off or make me masturbate over her while she fingered herself. She was really into me coming on her tits. She would then use her fingers to wipe off my cum and eat it as I watched her. She really liked watching me watch her eating my cum. She would then keep sucking my cock until I was completely limp dry. We never actually fucked except that one time with my sister.

Eventually, Lisa became my girlfriend. I did not spend much time with mother after that. Lisa was on the pill and all she ever wanted to do was fuck. We fucked all the time. She very rarely gave me blowjobs because we would always end up fucking first. Lisa and my sister were always good friends. I swear there were times when I thought they were having sex with each other but I was never able to confirm. The idea of all three of us having sex together in bed would drive me crazy but it never happened.


A couple of months after my crazy two weeks with my sister I was home alone. I went exploring in my mother's room and I found her diary. She hid it in the box spring mattress of her bed. She must have used a box cutter to create a slit on the side to slipped it in. I found the key taped to the bottom of her underwear draw. I read most of it. But this one entry really stood out because it was about my sister and it happened only a few months before our crazy two weeks of having sex with each other. She wrote it by hand but I'm typing it into my computer to post. She has amazingly good hand writing. It's like a computer printer. Here's what she wrote:

I can't believe what just happened. I love Kim so much. I hope this doesn't scare her or something. She is so precious to me I would not be able to stand it. It wasn't meant to be this way but it just happened. It happened to me and I turned out okay. Well, mostly okay. I think she will be fine. This is all John's fault. I know he's cheating on me. It all started today when I got home from work. John is away on his "business" trip. But I know he's up to something. I was able to figure out his laptop password. Using your dog's name 123 for your password is really dumb. I was snooping around. The idiot doesn't know how to clear out his browser cache either. He's into some really effed up porno. Then I found an Email from Susan. Who the eff is Susan? Apparently Susan and John have be sending sex Emails back and forth. I have to admit the Email from Susan worked for me. I could feel my juices starting to stir and I found myself rubbing my clit as I read it. Anyway, so there I was after reading this effing Email and feeling sad I might be losing my husband. I was sitting there thinking about the time in high school when I was dating Jeff the co-captain of the football team and he dumped me. Now I was really sad. Just then my daughter walks in. I was getting ready for bed and I'm only wearing my bathrobe. She must have just come out of the shower and only had a towel on. She says, "Mom, do you have any more of the hair bands you buy for me? Mom, what's wrong?" She must have seen I was crying. I said, "Nothing" as I stared forward. She knew I was lying. So gets on the bed with me and puts her arm around me.

I instantly start thinking about the time when Jeff broke up with me in high school. I was only 16 and I was so distraught about Jeff dumping me. I was crying on my bed in my room for hours. My mother comes in and sees me crying. She says, "What's wrong sweetheart?" I tell her about Jeff. She tells me everything will be fine but that just makes me cry even harder. I was so distraught I actually wet my pants with a little pee. My mother says, "Let's get you ready for bed." She takes off my shirt and bra. But I am so distraught I just don't care. She takes off my pants and socks. She takes off my panties and says, "Your panties are wet. Oh sweetheart. I'll be right back." She comes back in with a warm wash rag and rubs it around my pussy. It feels really good and I mostly stop crying from her distraction. She gently uses her forefinger to wipe around my pussy lips. She is actually pressing her forefinger inside a bit and I swear she rubbed my clit up and down a few times. She's working it around and then goes really low. I can feel her wipe the rag across my asshole with her finger. It feels really good.

There I am on my bed completely naked. She gets my nightie and slips it over my head and tucks me into bed. But she gets into bed with me and I scoot over. She tells me to lie there quietly. The sheets were cold and snuggling next to her felt so warm. Under the covers she's lightly dragging her fingers over my body. It feels really good and calms me down. After a while I stop thinking about Jeff. I felt a ping of chills rush over my body every time her hand brushed over my pussy area. She would also drag the back of her fingers lightly over my tits. My nipples were instantly hard and it felt so tingly. Her caresses really had all of my attention and I was able to finally calm down. Then she says, "See, there are ways to forget about boys who break our hearts." After she says this she puts her hand on my pussy. She knows just how to press her fingers into me. As she's rubbing my pussy and it feels really good. My mind is gone. I could not say anything because I was just getting over crying so hard about Jeff. I just let her do whatever she wanted to do. And it felt really so good I just didn't care. This went on for some time and then she pulled my nightie up and put her fingers directly on my pussy area. It felt amazing. She pressed a little harder until her fingers were slightly inside me rubbing up and down against my clit. I couldn't help myself at this point and I was moving my hips up and down to meet her hand. Soon I was no longer able to control myself, my body stiffened, and I had a huge orgasm into my mother's hand. It felt so amazingly good. I was so relieved and spent. It felt like every emotion in my being was drained away from my body. I just fell asleep in her hand.

We never talked about it after that and nothing ever happened again. But this is what was on my mind when my daughter put her arm around me to console me on my sadness. My daughter then starts rubbing my shoulders and says, "Come on mom, you need to relax. Whatever it is everything will be fine." All of sudden my daughter is acting like my mother. And it made me feel better so I didn't care. After rubbing my shoulders for awhile she tells me to take off my robe and lay face down. She starts rubbing my shoulders and back. She starts working her way down my back. She starts rubbing my lower legs and works her way up. A few times she was rubbing dangerously close to my pussy lips. I spread my legs just a little apart without thinking. She starts rubbing my butt but only briefly. She hops over and starts rubbing the other leg the same way. She then hops between the lower part of my lets and starts rubbing both my legs upward. She starts with her hands on my calves. She then rubs the back of my knees. She then works her way over and around the back of my thighs. When she gets to my butt she starts rubbing in circles. Each time she goes around she is slightly spreading my butt cheeks. It feels very good and I begin to get tingling sensations in my stomach and pussy. She's doing a really good job. I don't know how many times I let out a, "Mmmmmm". At one point she was spreading my butt cheeks and I swear she was lightly blowing cool air on my sphincter. It felt amazingly good. It kind of felt like she was licking me. But I know it was just cool air. Maybe she was just lowering her head down and smelling me and I was feeling her exhale on me. I'm not sure.

She then tells me to roll over. I felt like I was under her control so I just did whatever she said. She started rubbing the top of my shoulders. I just closed my eyes. My breasts and pussy are on display but my daughter has seen my naked body many times. She's rubbing my shoulders working her way down to my breasts. She was gently caressing her fingers in circles around my breasts. Occasionally her finger tips touch my nipples which are extremely erect at this point. She works her way down to my stomach. She's rubbing the area above my pussy and occasionally her finger tips would run through the top of my pussy hairs. She then starts rubbing my legs. Every now and then she is coming dangerously close to my pussy lips. She then starts caressing her finger tips over my pussy hairs. She would start low and drag her finger tips upwards over my pussy hairs. Her light touch on my pussy hairs was very exciting. I felt like I was getting wet. At this point my daughter completely succeeded in getting my mind off my sadness.

Without really thinking about it, I reach out with my right hand and I started caressing the bottom of her butt area. Her towel was covering most of her back but my hand was able to reach underneath her and I started to caress butt and pussy hairs. I started doing the same thing to her she was doing to me. My finger tips were touching her soft butt skin an occasionally I would feel my fingers tips glide over her pussy hairs and pussy lips. My finger tips were lightly strumming her butt and playing her pussy lips like a musical instrument. We kept caressing each other for several soothing and tingling minutes.

Kim then takes off her towel and puts it to the side. She then moves her leg over and straddles my head. She then lowers her pussy down over my mouth. It just felt so right and natural I did not protest her doing it. I simply start licking her. I have tasted my own pussy juices before and it has always excited me. But I never licked someone else's pussy before. It was so much better than anything I ever imagined. I was really getting excited and so was Kim. She was using her fingers to rub and massage my clit the whole time. My clit feels almost painfully swollen at this point like it was about to burst. Kim knew exactly how to move her fingers to rub it in just the right way. As she's rubbing my throbbing clit she continues to press her pussy into my face. I'm working my tongue furiously. It did not take long for Kim to orgasm. Her body got really tense and she was letting out the sweetest little moans. I think she was trying to be quiet so her brother who was most likely playing video games in his room would not hear what we were doing.

She then rolls over and gets between my legs. She looks up at me and our eyes meet for a brief moment. Her eyes were slightly glassy and there was no doubt in my mind that she was completely possessed by the moment. She licked my pussy once, paused, and then she started licking my pussy furiously. She was amazing at licking my pussy. She is so much better than my husband ever was at doing it. Plus her soft face pressing against my legs and pussy area was so amazingly hot. Men's whiskers suck. It did not take long and I think I orgasmed more than once. I was not as quiet as Kim. I think maybe our next door neighbor might have heard me at one point. Hey, sex is part of life. I don't care what they think. It's my orgasm not theirs!

Afterwards Kim climbs up into the crook of my arm. Her head is now resting on my bosom. Her mouth is only inches away from the nipple of my right breast. I can feel her exhale lightly brushing over my nipple. My nipple is uncontrollably erect as she's breathing on it. She's watching it with her eyes and she asks me, "Why were you so upset before?" The whole thing comes back to me in an instant. I tell her about what I suspect is going on with her father. She assures me I may be misinterpreting the whole thing. I tell her, "Don't worry, I will make him pay. Your father is my sex slave. I will make him tell me exactly what he's doing. He belongs to me!" I can tell by the look on her face she was little taken aback by my proclamation. That's okay. I really will make him pay if he's cheating on me. Even if he isn't cheating on me I will make him pay. Maybe during one of our sessions I will arrange for Kim to watch him serve me without him knowing it. Maybe I will force him to lick Kim's pussy if she lets him. This is going to be so much fun! I can't wait!


After I read my mother's diary she said she would try to arrange for my sister to have sex with my father. I decided to try to find out if it ever happened. My sister went to the bathroom one day and from the door to her bedroom I could see her computer screen saver had not kicked in yet. I rushed in and before it locked up I was able to see she was posting to an online diary website. I was able to find the name of her user account from the site's profile page. But I did not know her password. After a week of trying to figure it out I finally found her password written on a piece of paper taped to the bottom of her desk draw in her room. I started wading through all her diary entries. It took me a while because it turns out my sister is one crazy little fuck monkey. Several times I had to stop reading and go spank out some relief. I found this entry to be one of hottest ones I read:

I had sex with my mother again last night. I still can't believe we are now having sex together. The first time we were together she was driving me crazy with her fingers. She made me so freaking hot. Things just avalanched after that. Her licking me was amazing. It still gives me chills thinking about it. My mother and I have always been very close. I love her very much. We know each other so well. Sometimes it feels like we are the same person.

It's Sunday night again and I knew she was going to have sex with my father. I had to see what she meant about him being her "sex slave". So I timed it just right and snuck into their closet and hid myself under some hanging cloths. My parent's closet has pairs of hanging folding doors so I knew I could just crack it open once they got started. I was so hot waiting for them to start. I must have been dripping wet with sweat. It took forever for them to get started. The anticipation was almost unbearable so I started rubbing myself and fantasizing over what they might do.

There was a moment when I thought I was caught. Mother spreads out a quilt on the floor then comes over to the closet. It's a double closet and she opens the other side. She pulled out a box that was underneath some stuff. She goes over to the bed. She puts the box down on the bed and in a somewhat authoritative voice tells my father, "take off your cloths and assume the position." I've only caught glimpses of my father naked. It was very exciting to be watching them secretly. He's now standing their naked. I think my brother's cock is bigger than his but I'm not sure. My father then kneels down on the quilt. He puts his hands behind his back. My mother slips a mask over his head that she took out of the box. The mask was made of leather and it did not have any holes for the eyes. The mask only had one hole for his nose and mouth. She then tied his hands behind his back with a piece of white rope. She then put on him what looked like a dog collar with a leash.

She drops her bathrobe and is now completely naked. She then gets down on the quilt holding the leash. She's on all fours with her ass up in the air and says, "Lick my asshole slave." And she pulls his head forward with the leash. My father starts licking my mother's asshole. He starts digging into her with his tongue and licking furiously. As he is licking and probing my mother she is letting out soft moans of pleasure. It's really hot to watch. I find myself rubbing myself vigorously because I am so turned on by what they are doing.

She then commands him, "Now fuck me up in the ass slave. Fuck me hard." My father then takes his dick into his hand and inserts it into my mother's asshole. He starts fucking her up the ass. He's thrusting his hips back and forth and I can see my mother's tits swinging back and forth. My mother continues to moan in ecstasy with each thrust. I am very excited at this point. I am one or two rubs away from having my own orgasm. Before I do my father lets out a groan thrusting his hips forward and his body remains tense for a time. I can see he's releasing his load of cum into my mother. Eventually he pulls out. My mother turns around grabs his cock and she starts sucking and licking on it. Her head was bobbing up and down for some time. Seeing my mother suck on my father's cock was so freaking hot!

She then reaches around and digs her finger into her own asshole. She then takes it out and starts sucking the cum off her own finger. She does it again accept this time she shoves her finger into my father's mouth. He just starts licking his own cum off her finger! She then says, "Slave, clean up your mess." She then turns around and returns to being on all fours with her ass up in the air. She pulls on the leash again. My father starts licking his own cum out of her ass! My father really is her sex slave! I just can't hold back any longer and I orgasm in the closet. I accidentally let out a slight moan as I did. My mother turns and looks right at the closet! She definitely heard me moan!

After several intense seconds staring at the closet, she turns around and grabs him by the chin. She leans over and starts French kissing him. I was thinking they've must have been tasting cum in each other's mouths. She then pushes his chin away and says, "I'm done with you slave, get dressed." My father was completely limp at this point. My mother removes his mask and puts the collar and leash back in the box.

She then turns to my father and says with a sweet and gentle voice, "Honey, go downstairs and watch TV. I will be right down." I was like, "Wow, that's a switch!" She then kisses him sweetly on the cheek. My father must have still been in slave mode because he just got up, got dressed, and did exactly what she told him to do.

She walks over to the closet and says, "Kim, come out, I know you are in there." She looks a little irritated with me and she seems a little embarrassed by what I had just witnessed. She started giving me excuses like, "When you've been having sex with someone for a really long time your needs change. Your needs become more sophisticated." This went on for a couple of minutes. I finally said, "Oh shut up mother. I've seen a thousand times worse on the Internet. What you and daddy were doing was tame by internet standards." This wasn't exactly true. I think what I saw was pretty much a 10 on the freak scale. I then said, "But it was sure fun watch!"

She stopped talking and just stood there thinking about what I had just said. I then said, "What does it taste like? I really want to taste what sperm tastes like." She looked at me and she just knew I wasn't going to take no for an answer. She replied by saying, "Well, I still taste it in my mouth. You can kiss me if you want." Without thinking I leaned into her and started kissing her. I moved my tongue in pretty far exploring around because I want to get as much flavor as I could out of her mouth. It tasted really yummy to me but I wanted more.

I then said, "Bend over momma. I want to do what daddy was doing". She said no at first but I pleaded with her using my soft manipulating voice, "Please." She then reaches around and using her finger she presses it into her asshole. She wiggles it around a bit to get some cum on it. She pulls it out and brings it up to my face. I practically swallowed her finger when I sucked on it. I told her I wanted "More, more, more!" She finally agreed to bend over. I scooted around and got on my knees. I spread her butt cheeks and started licking her asshole. I never did this before but once I tasted the sperm still oozing out of her asshole it was so hot! I was so out of control. I just started licking and lapping it up as fast I could. It tasted so good. I was fingering myself the whole time and eventually I had my second orgasm. I could tell my mother liked what I was doing because she began pressing her ass into my face. It was so freaking hot. Every now and then she would squeeze her muscles a little and more cum would start oozing out of her asshole for my eagerly awaiting tongue. My clit is tingling right now as I write this.

She then tells me it is my fault my father is watching TV instead being with her. She said I would have to be her temporary sex slave and finish what her father has started. I eagerly agree and ask her what she wants me to do. She gets on the quilt and tells me to start licking her pussy. I just wanted to please her. I would have done anything she ask me to do. It does not take long for my mother to finish. After that I helped her straighten up and I then went back into my room.

I spent the rest of the night watching internet porn. I never knew so many people were into licking assholes before. It was so freaking hot watching people licking assholes. I orgasmed a third time after watching a really hot video. In the video a guy was commanding his little sister to lick his asshole. Oh my God, it was so freaking hot! My brother would never tell me to have sex with him. He's too much of a computer nerd.

My brother and I and been flirting with each other the last few days. We've been masturbating in front of each other while watching porn after our parents go to bed. I was so close to giving him a blowjob the other night but he went off into the bathroom the stupid jerk. Tomorrow night or the next I'm going to go for it. I just need to get up a little more courage to give him a blowjob. It just looked so big in front of my face I think I was afraid of it. After tonight I think I can really do it. I just want to taste sperm again! The taste of sperm is just so amazingly hot! When I was younger we lived in smaller house on the other side of town. There was a Callery Pear tree outside my bedroom window. I just loved the way it smelled in the spring when it was blooming. It's one of my best memories growing up. I swear sperm tastes just like the way my Callery tree smelled! I loved that tree.
