Laurie's POV
He grabbed her breast and caressed it lovingly making her throw her head back and moan. He gave her a deep kiss and thruster in to her long and slow. He gave her a deep loving kiss as they both went over their edge.
Laurie sighed and she thrusted her hand in her vagina one more time and she silently climaxed. She threw her erotic novel on the floor and thought "I hate my life". Red had grounded her because he caught her fucking a guy in her room and now she was grounded and what's-his-face was in the hospital. And for once she couldn't talk her over-protective father out of this. She couldn't leave the house since Red nailed her window shut and she desperately needed to get laid.
She knew what she had to do. She put on a bra and a thong and silently crept out of her room and went to Eric's room. She burst in and saw him masturbating to a naked picture of Donna. He jumped and pulled the covers over his dick and stammered out "W-what are y-you doing here L-Laurie?" She came to his bed and stood next to it "Little brother as you know dad grounded me so I can't leave. Since I can't fuck someone out there I have to fuck someone in here." Eric was about to protest but she grabbed his cheek and squeezed like he was two years old. "Shut up little brother, it's your lucky day." She reached in between her boobs, pushing them up a little and undid her bra and let her large DD's burst out and bounce some and threw her bra at Eric's face. She reached down to her waist, hooked her finger under the straps of her thong and slid them down revealing her neatly shaven. Once she had stepped out of them she also threw them in Eric's face, making the part of the thong that covered her pussy land on his mouth. She did a quick sexy spin showing her brother all of her assets. Once she completed her spin she knelt down on the floor by his waist and grasped his cock.
Eric's POV
Eric was freaking out right now. Right now his slutty sister was basically telling him she was going to fuck him and that really turned him turned on. Eric reached up to his face to pull Laurie's thong off, but he involuntarily sniffed it. Eric got harder just from one sniff of his sisters pussy and he knew he had to smell the real thing but Eric couldn't concentrate enough to do that. Right now Laurie had her hand wrapped around his dick stroking it and licking the head a little. Eric debated either fucking his sister or telling his mom. The decision wasn't hard. Eric leaned his head back, closed his eyes, and groaned as Laurie worked her magic on his cock. Once she got him to his full length, around thirteen inches and two inches thick she sandwiched it in between her large breast and started to go up and down on it so the head of his dick popped of the top of her boobs. "Wow Eric I didn't know you had such a big cock. I might have to get grounded more often." The feeling of her large tan breast around his dick was amazing. It was so soft and warm Eric almost came just from the feeling of his sister's boobs surrounding his dick. At first Laurie moved her boobs up and down at the same time then she raised one up and lowered the other then she did little circles with her boobs. She did one for a while then she switched back to the other then switched again. She kept switching what she was doing to Eric's member that his mind just went fuzzy in pure pleasure. Eric felt Laurie put her mouth around the head of his dick and suck on it and she swirl her tongue around his head adding to the already large amounts of pleasure Eric was receiving. Eric moaned in pleasure. He felt his balls tighten and said "I'm gonna cum sis." He felt Laurie remove her boobs from around his dick an Eric felt sad but Eric quickly felt something very hot and very wet be replaced on his dick. Eric opened his Eyes to see what was on him and what he saw amazed him. Laurie had the almost the entire length of his member shoved down her throat. The few inches she didn't have in her throat she was jacking off. After a few seconds Eric blew his large load down his sister's throat. He fired off thick rope after rope of cum in to his sister. When Laurie thought Eric was done cumming she pulled her head off his dick but Eric wasn't done yet. He blew off one more load that landed on her cheek and trailed down her neck and stopped on her boob. Laurie gave Eric a look of fake disappointment and said "Don't you know it not nice to jizz on your sister, Eric." She reached up and pulled his essence off of her skin and ate it.
She rose off of the floor and gave him another look at her pussy and Eric remembered the smell of it from her thong. He decided 'what the hell' and reached over, grabbed Laurie's nice wide hips and placed her pussy over his mouth. He gave her one long lick along the slit of her lips making her let out a long low moan. He felt her legs on either side of his head squeeze together a little more and he felt her hand reach down to his head and forcefully grab a handful of his hair but Eric didn't mind. He delved his tongue inside his sister's pussy and explored it, licking every inch of her of her pussy. He loved how sweet she tasted. While he was eating out his sister's pussy, Eric's hand had reached around to her ass and he was cupping each of her cheeks in his hands. He was pinching her ass and occasionally he would slip a finger or two in to her ass. Just kept slurping on Laurie's cunt and nibbling on her clit while she slowly humped and grind on her brother's face. Eric felt her legs tighten even more around on her humping her face grew erratic letting Eric know his sister was close to climaxing. A few seconds later Laurie let out a long low moan and she drenched Eric face with her love juices. Eric tried to drink up all of sweet nectar but he missed some and got it one his face.
Laurie's POV
Laurie was in pure bliss and amassment. First she found out her 'baby' brother had a forearm growing out of his waist and now she found out he could eat pussy like a pro. She was sitting on her brother's face for half a minute and he already had her about to cum. She had one hand squeezing one of her large breast with her left hand and had a fist full of Eric's hair in her right hand. She felt herself reach her climax and she squirted on his face. When she got done cumming she got off her brother's face and decided to stop the foreplay.
Eric's POV
Laurie straddled him and sat down on his waist but not his dick. She sat so his dick being pushed down by Laurie's plump ass, so Eric could feel the very bottom of her ass crack, causing some pain at the uncomfortable angle, and she leaned over his face and looked down at him "Awww looks like I got you all dirty too little bro. Let me clean up." Laurie leaned down and started to clean her sweet juice off her brother's face with her soft, warm tongue. When she was done giving her brother a bath she gave him a deep kiss giving Eric yet another taste of her sweetness. Laurie pulled away from the kiss and raised her hips again so Eric meat stick was right under her waiting cunt. She put on a sexy face and asked her brother in a sultry voice "You ready for the ride of your life?" Eric nodded and she started to lower her pussy on to her brother's dick. Laurie let out a moan because Eric was the biggest cock she had ever had in her, which was saying something. Eric let out a groan also because even though she wasn't as tight as Donna, or even Jackie, she had a well toned stomach and knew how to maximize the tightness of her pussy. Once he was all the way inside of her she just sat there for a few seconds to adjust to the stretching he was giving her. Once she adjusted to him she started to slowly on his cock then sped up until she was wildly bouncing on her brother making the bed creak. Eric was surprised by her assault on him, riding him like a bucking bronco, but he quickly recovered. He placed his hands on his sisters bouncing breast and started playing with them. He squeezed and massaged her flesh and he tweaked her nipples. She arched her back trying to give him more of her boobs to play with. After a little while of plying with her boobs Eric leaned up and started to suckle making Laurie moan even more. Laurie kept slamming own on Eric for twenty minutes before her down ward thrust became erratic as well as Eric's upward thrust. "I'm going to cum sis what do I do?" Eric asked. "Blow it in my little brother I want all of your cum in my slutty little vagina". A few seconds later Laurie bent down to Eric and captured his lips in hers and she came and let out a moan in to her brother's mouth. Eric felt his sister's pussy convulse around his dick and he emptied his sack of incestuous cum into his sister's vagina. They made out like that a little while longer until Laurie pulled off of him and got off the bed and walked to the foot of his bed and put her hands on the foot board of his bed. She looked at him and asked "Got another round in you?" "You bet sis" Eric quickly got behind Laurie he put his hands on her nice wide ass, pulled apart her cheeks, and rammed his cock into her ass making her let out a loud screech. Eric didn't give her time to adjust he just kept ramming his cock into his sister's ass repeatedly. Laurie was screaming her head off, apparently not caring if Red or Kitty caught them fucking. Come to think of it he didn't either. Laurie was shouting "THATS RIGHT LITTLE BROTHER FUCK YOUR SISTER LIKE THAT! YOU SO GOOD AND BIG AND FILL MY ASS UP SO GOOD! AHHHHHHH!" She orgasimed and Eric felt her ass clamp down on his cock but he wasn't ready to give it to her just yet. Eric stopped his thrusting until Laurie came down from her climax. When he felt her ass muscles relax he stated his assault again. He kept pounding on her for an hour until Laurie climaxed again and this time Eric couldn't stop himself and her released deep in his sister's fine ass.
Eric pulled out his dick that was covered in a mixture of his and his sister's liquids. He gave Laurie ass a smack and watched as it jiggled and he got another idea "On the bed, on your hands and knees." Laurie did as she was told and got on the bed. When she got on the bed she looked back at him with a mischievous grin and wiggled her ass at Eric. He quickly got behind her and put one hand on the small of her back right above her ass and rapped the other around his dick. He held the head at her lips and tickled her with his organ eliciting a small moan from his sister. "God fucking damnit Eric just shove your giant cock in my pussy dumba- AHHHHHHH!" Eric slammed all of his meat in his sister's cunt catching Laurie off guard. Eric slid out hard and fast out of his sister's pussy that was gushing with their combined incestuous fluids. Laurie could no longer support herself under Eric's relentless assault and was now getting her face fucked into the pillow muffling her loud moans and shouts. Eric started squeezing and pinching her wide soft ass making it lightly pink then moved his hands from her ass to her jiggling breast for more leverage so he could make his thrust more powerful. Soon Eric felt the need to blow his load so he quickly flipped his sister over and kept pounding away. He didn't want Laurie to scream so he shoved the palm of his hand over mouth forcefully and kept a death grip on her other tit. Eric looked in to his sister's and saw a mixture of surprise, pain, and pleasure in there and he licked that look. The climaxed at the same time and Eric collapsed on to his bed next to her. Once she recovered she propped herself on her elbow and looked down at her brother. Now that he got a better look at her he noticed a little bit of blood coming out of her mouth from where he covered her mouth and her teeth cut in to her lip and that one of her breast was bright red from his grip, but she didn't seem to care about her condition "Wow Eric where did you learn to fuck a bitch like that" Laurie asked surprised. Eric smirked and rubbed her breast that was in better condition "You got to give me a really good reason to tell me, but…" he tweaked her nipple making her giggle "I think you could find a way to find out." She reached down and started rubbing his limp wet organ and said "Well since I am grounded for a while I can take my time figuring out, but for now we got to sleep so I got to leave." Laurie sat up and was about to get up but Eric gabbed and ass cheek and pulled her back down "No you don't in need a pillow and your are the best one I could find my slutty big sister" and with that Eric laid hs head down on his sister's soft boobs and fell asleep.
Laurie's POV
Laurie laid on Eric bed with her brother nuzzling in to her breast and realized how not boring being grounded could be.
