Max woke up to the sound of Barb pounding on his door. Did she know what was happening between him and Phoebe? Did she hear about their activity last night? Whatever it was, she was ticked and he got up right away. Barb stormed in, still wearing her nightgown, angrily walked over to Max's bed and got right in his face.

"Max, just what were you thinking?!"

"What, what did I do?"

You fuck Phoebe and then send me the video? What kind of sick twisted person do you think I am?"

"Oh shit."

"Yeah, oh shit. You sent me the video last night, now luckily your father hasn't seen it, but I cannot believe you would have sex with your sister and then send it to me!"

"I'm sorry Mom, it just kinda happened yesterday. We were just hanging around and one thing led to another."

"How many times have you two fucked? Huh? How many Max!?"

"Three times, all yesterday."

"I'm gonna go get Phoebe and the three of us are gonna talk about this once the kids leave."

Barb stormed out of Max's room with a little bit of her ass hanging out. Max eyed her up as she left the room before quickly sending Phoebe a text warning her about Barb. Phoebe woke up to the text, seeing it was from Max, smiled and went to get her phone. Her smile faded once she saw the contents of the message. No sooner had she finished reading it when Barb knocked on her door.

"Come in." Phoebe sheepishly said.

"Phoebe, tell me the truth, have you and Max been fucking?"

"Yeah, it started yesterday and we didn't mean for it to happen, but it just did."

"How the hell does it just happen? You know what, never mind, I don't want the kids to hear about this right now. When they leave you and Max come to my room and we will discuss this thoroughly."

Barb stormed out of Phoebe's room, again having her ass hang out just enough for Phoebe to get a glance at. Phoebe ran down to Max's room and confronted him.

"How did she find out Max?"

"I might have sent her the tape of us fucking last night."

HOW could you do that? Why would you send Mom the tape?!"

"I meant to send it to you, I must have just misread the name and sent it."

"How could you be so careless, we had a great thing going on, and now it's over. Mom is gonna tell Dad and we are never going to see each other again."

"I know, I know. I'm so sorry Phoebe. I just wanted to show you how great we looked and forgot to look at the header."

"Well your carelessness might have cost us everything."

Phoebe ran out of the room trying her hardest not to cry. She didn't want the best thing she had ever had to be taken away over a dumb mistake. Maybe Mom would see that they were in love and were destined to be together. She tried to cling to that hope as she got ready for the day. As she stepped in the shower, she could only think about the day before and Max watching her. Even in this stressful moment, she was still turned on by him watching her. She remembered the emotions that ran through her as she watched him watch her. She desperately wanted that moment again.

Eventually everyone except Barb, Max, and Phoebe had left the house. Max and Phoebe walked up to their Mom's room. They didn't say a word, what could be said at a time like this. As they opened the door they were shocked to see their mother standing there bare naked. She had the video open on her laptop and was playing it, while masturbating. She was getting off to her own kids fucking.

"MOM!" They both shouted.

"Oh my gosh, um hi kids. I guess everyone's gone huh? Maybe we should talk."

Barb put the laptop away and covered herself up partially. She was still wearing the nightgown and it did a poor job at covering up anything private. She motioned for them to sit on the bed, one on each side.

"Max, Phoebe, there's something we need to talk about," She started. "First of all, I can't believe you two are fucking each other. But I must confess, it's very hot."

"Mom, what the hell are you saying?" Max asked.

"I'm saying that seeing this video of you two fucking turned me on so much. I've never seen such a passionate couple in my life!"

"So you're okay with us fucking each other and being together romatically?" Phoebe questioned.

"At first, no I wasn't. But, after seeing the two of you on camera, it's clear to me that you belong together. However, I have two rules if this is going to continue."

"Anything, just name it." Phoebe said.

"One, you can NEVER tell anyone about this, none of your friends, no one in this family, or anyone ever. And two, whenever I want, I want to be able to join in and fuck as the three of us."

Phoebe and Max's jaws were on the floor. Was there mom asking them for a threesome? Surely they were both dreaming? There was no way their mother wanted to fuck her own children?

"Are you being serious mom?" Max and Phoebe questioned.

"I am 1000% serious. I'm okay if you two have your own time together, but whenever I want to fuck, the three of us fuck. Now it could happen that only Max is around or only Phoebe. That's fine too. I just want to fuck whenever I say. Okay?"

"Sure!" They both agreed.

"When would you want to start?" Max asked.

"How about now?" Barb suggested. "I'm clearly in the mood, so let's get this party started."

"Okay, let's go!"

Phoebe and Max got up and undressed. Both started kissing Barb's tits. They licked and played with the nipples. Barb was moaning in delight, as she slipped off the pesky nightgown. She ran a hand and began playing with Phoebe's tits as well. She also reached down and started playing with Max's cock. She was amazed at the size of Max's cock. It was way bigger than what she was used to with Hank. She moved Max off of her tits and began kissing him. The two made out while Phoebe kept sucking her mom's tits, now giving both attention. Phoebe could see that Max was getting super turned on and his cock was huge. She took her free hand and began jerking him off. She slowly moved her hand up and down her brother's shaft.

Barb broke the kiss off from Max. She then pulled Phoebe up and began making out with her. Max brought his attention to Barb's pussy; he couldn't believe how amazing it looked. She had 5 kids and it still looked incredible. Phoebe's was tight and young, while Barb's was older and experienced, it gave him something new to try. He took his hands and began fingering Barb and Phoebe. Both moaned in pleasure as Max continued. He then took his tongue and began eating Barb out. Barb was delighted as Max kept eating her out. She put her hand on his head and pushed his head farther into her pussy. Max and Phoebe were making her feel things she hadn't felt in a long time.

Barb took Max and laid him down on the bed. She then laid on top of him and put her pussy in his face. She and Phoebe brought their attention to Max's cock. They both began sucking and licking his cock. Phoebe would play with his balls while Barb would suck. Once Barb would come up for air Phoebe would get some sucking in. They were competing to see how much they could each take of Max's cock. Phoebe surprised Barb by being able to take all of Max's cock over and over. This challenged her to take as much when she sucked, it was hard as Barb was not used to the amount of Max's cock being in her throat. Nevertheless, she continued sucking while Max continued to eat her out.

Eventually Barb was tired of just sucking Max off. She got off of him and placed her pussy right over his cock, with her looking at him. She tensed as she prepared to take it all. Would she be able to after years of barely anything? As the tip of his cock entered her pussy she breathed in sharply; there was no turning back now. She took a deep breath and slammed down on his cock, taking it all in. She gasped as he filled her, not expecting it to be that deep. Phoebe watched as she got over Max's face and let him eat her out. She also began making out with Barb as she rode Max making a perfect triangle.

"Oh, oh my gosh Max, how have you kept this hidden from me so long?" Barb asked, panting from going up and down on his cock.

Max didn't answer, not because he didn't want to, but he physically couldn't. Phoebe was riding him that hard. She grinded on his face at a furious pace. Meanwhile, Max brought his fingers up to Phoebe's asshole and began fingering her. Phoebe's ass had become looser since the first time he penetrated her, yet she still moaned in delight when Max fingered her.

Barb could feel herself cumming soon. She didn't want to end the fun yet, so she got off of Max and let Phoebe get fucked by Max. Phoebe got on her back and pulled her legs behind her head so Max could do whatever he wanted. Max, knowing her ass was ready, lined up his cock with her ass and began fucking her. His strokes started a bit slow and then began getting faster and faster. Phoebe loved every second that her brother fucked her ass, it made her so horny that she was getting fucked in her ass that she began rubbing her clit and fingering herself. Barb reached over and stopped her from fingering herself and instead began fingering her instead, which then led to eating her out. Phoebe, now taken in both holes, began fingering her mom and eating her out as well. She could taste Max's cock in her mom's pussy. As she ate her out, she took one finger and traced it along Barb's asshole. Barb shot up startled that Phoebe was potentially trying to finger her ass.

She nodded in approval and went back to eating Phoebe out. Phoebe slowly began putting a finger in her mom's ass, making sure it was wet enough so she wouldn't hurt her. Barb moaned as she was being fingered. Phoebe began putting a second and third finger in as Barb seemed to really enjoy her ass being fingered. Max was still fucking Phoebe's ass and he was thrusting harder and harder with each stroke.

Barb and Phoebe were both about to cum. They could sense that they wouldn't last much longer and started to lose control. Barb came first and squirted all over Phoebe and her face, with most going into her mouth. Phoebe came as Barb did and came all over Barb, including most going into her mouth.

Max jumped back seeing both girls cum at the same time. He was yet to finish and now both had cum at the same time. Barb climbed off of Phoebe and kneeled before Max and began jerking him off. Phoebe got off the bed and kneeled next to Max and jerked him off as well. She played with his balls and his cock. Max felt that he was about to cum and took his cock from Barb. He jerked himself off until he finished all over Barb and Phoebe. He got cum all over Barb's face and got some on Phoebe. Max moaned in pleasure as he finished.

Barb, still covered in Phoebe's cum, took some of Phoebe's off her and mixed it with Max's and placed it in her mouth, swallowing the mixture. Phoebe took some of Max's cum off her mom's face, mixing it with her mom's and did the same. Together they both got all the cum off each other. Then they came together and kissed, bringing the two mixtures together, and bringing them to each other's mouths.

Barb made sure that Phoebe didn't spill a drop and Phoebe did the same to Barb.

Once they were finished and everyone had caught their breath, they got up on the bed and cuddled the three of them with Barb being in the middle of them.

"Can we do this all the time?" Phoebe asked Barb.

"We sure can," Barb said. "Whenever you want, just come ask, and we'll fuck."

"Awesome." Max said.

"Yeah it sure is. Now get out. I gotta clean this place up before your dad gets home." Barb said as she got them up and out of the room.

As Max and Phoebe walked out of the room they picked up their clothes and held each other's hands.

"I can't believe mom was okay with us fucking." Phoebe said.

"Yeah, what I can't believe is that she wanted to fuck us too." Max replied.

"I'm definitely taking her up on that offer."

"Me too, but we're still gonna fuck on out own right?" Max asked.

"Definitely babe, you're the only guy for me. How about tonight?" Phoebe questioned.

"Sounds good babe." Max replied.

"Okay, perfect," Phoebe said as she kissed him. "And how about sending ME the video this time?" She joked.

"Haha, but if it wasn't for me, we would never have fucked mom."

"I guess so. But still send it to me okay?" Phoebe said as she walked into her room.

"Fine, I'll do it when I get back to my room." Max said as he walked back to his room.

Soon enough the rest of the family returned home and none were the wiser about the earlier exploits by Barb, Phoebe and Max.
