As the door closed I told Mia "take your top off so I can see our tits."Sis stripped off her blouse and stood there looking half shy. "They are your t...t's brother" she whispered looking at me with a smile. "All yours now."I crossed to Mia and started to kiss my sister's mouth, frenching her and fondling her. Sex with Mia had changed me and now I wanted her body all the time."Brother as long as you touch me, fuck me, cum inside me, I will be normal. When you touch my breasts, I feel it, feel. I don't know if it was the beer or shear willpower but Dad was lasting a long time as his wife strove to make his cock squirt. Finally with a loud grunt Dad shot his cream into my mother's mouth. She swallowed grinning up at him. "Let's go to bed. I'll get you hard again so you can fuck my ass good."I slipped into my room just seconds before my parents came down the hall on the way to their room. What a slut my mother was. In less than an hour she had swallowed three loads of cum from three. . All of a sudden I heard some giggling and it came from the pool. At least one chick had seen what I was doing and said something to the other women at the pool. Well... this only turned me on more...Once I realized she had seen me and told her friends I was even more turned on! That is the moment I've been waiting for (and you know that if you're an exhibitionist like me) They all looked over the edge of the pool and it was extraordinarily quiet... Then as I lay in the lounge chair not 25. I woke to the sensation of three women giving me a breakfast blowjob, it felt like my brain was never going to go back to normal. When they knew I was awake, the three looked at me and sang Happy Birthday and then took turns trying to blow out my birthday erection. I responded by blowing my birthday sauce all over their faces.In the shower, Lynn and Erin both took my ass with their strap-ons, and then Blossom used my pipe cleaner and lots of soap to wash me. I was then treated to the finest.
