It was Saturday evening; Darrin said he was heading to a party with his current girlfriend, so I knew I would have the place to myself. I stopped at t...e convenience store on my way home for some soda, snacks, and possibly something more substantial to eat. As I entered, I noticed one of the swimmers getting a soda. I ended up behind him in line and could still smell the chlorine from the pool. A quick once over told me he was going commando, maybe around 5'8" tall, his cut away shirt showed a. {Just how long were we in there? I only seemed to sense an hour at the most.} I asked her.{No Doctor Gance, you were under almost eight hours. It will be a few hours 'til your body returns to any resemblance of normal. All the corrections you made to my lower functions, have increased efficiency; they’re another twenty percent. Higher functions have increased another fifteen percent. Those that you did to me,} here Sheila sighed. {Have made so much more clearer, thank you, Roger. I was confused. It was about 1am and we were flirting back and forth but I figured it was just friendly flirting. She left the room and I was still working. She came back wearing just a bra and a g-string. My jaw hit the floor!!! I was like what are you doing???? She came up to me all slow and said “Shhhh...” She started kissing me and I didn’t fight it… I caressed her back and undid her bra, she was a little thrown back by it because I undid it without her realizing it. She lowered her bra and held her. With one big thrust she takes it all the way in. Balls deep she begins bouncing on my dick.. in and out her pussy walls been forced apart by my hard cock. Your sister playing with her pussy while your mum rides my cock like she hasn't been fucked in years. I look to your sister and tell her how sexy it would be if she kissed her mum. She pauses for a second. But then gives in to the Passion. Your s*s and mum sucking on each others tounges. Your sister pulls away and says its my turn. I want him.
