Slipped on my flip flops and exited the pool area.At this point I knew my wood was NOT going to subside until I busted a nut, but that was fine with m...e. When I'm all horned up like that I dig the way my johnson draws attention so I walked back into the building (naked except for my flip flops) and made my way to one of the small theaters. I found a seat on one of the fake leather couches and relaxed as I watched the fuck flick and stroked my hardon. At first I was the only one in that theater,. I looked down and her blonde head bobbing up and down and knew she would win the bet, it was hardening already.After a few minutes she pulled her head back holding my rampant cock in her hands and turning to Britney said “there, now it’s my turn”. “Well,” said Britney, “I’m impressed, with both of you, I never thought you’d get it hard that quick now let’s see you perform again Bill”. I couldn’t believe it but they led me into the lounge where Karen stripped off her nightie and sat on the sofa.. I mean, we've seen each other naked. Lots of times. We've skinny-dipped, played spin-the-bottle with friends, Truth or Dare, yes, but no sex. It's not unusual for either one of us to come out of the shower, towel off and run naked down the hall to our own room to dress. So, sure, we've seen each other but it's been hands off.Now, don't get me wrong. I'm seventeen and I'm a male. My sister is pretty, very pretty. In fact, she's one of the prettiest girls I know. And, yes, when I've seen her. ."Nora thought back to the previous Saturday night. Gawd, she'd been a total slut, begging for it! And Daddy said he knew she'd seen the videos -- undoubtedly, he'd seen what she and Nate did while viewing them... It just got more and more embarrassing... Armand nodded. "You showed quite a bit of your mother's buried sensuality that night. Off and on, though, a bit of me pops up..."Nora covered her face. "How much..." How much do I know? I haven't read your diary, but I've watched you write it..
