Let me tell you a bit about her, she wasn’t very tall, was a healthy girl, had fair skin, a nice plump soft ass you would want to squeeze all day lo...g…. Oh n most important, her boobs, they were something to behold. They were small but her areolas were BIG… It was an instant turn on for me. We decided not to get physical until we got married, something we decided with childish thoughts. But of course later our animal instincts got the best of us.A year had passed we were very comfortable with. The observation room is empty." Good, then let's talk while we know we have come privacy."Veronica, Brittany and Matt had just spent the last two hours complying with Betty's wishes (and their own) in a threesome that included every possible combination of bodies imaginable. Matt had lain on his back, buried in Veronica while Brittany straddled his mouth and he brought her to cunnilingual orgasm. After trading positions, Brittany had spread her legs to Veronica's tongue while Matt drove himself. My plan to bring her out of her shell was to bring home some help.I lined up three guys that I knew, Mike, Leo, and Al, and installed some restraints on our bed. On Saturday night, I meet the guys at a local bar for a few drinks, while Lucy stayed home to watch TV. After a few drinks, we weren't drunk, but were feeling pretty good, we all went to my house. I had talked to the guys about my plan, and they were all for it. They all had meet Lucy, so they knew what she looked like, but didn't. Matt's eyes got kind of big when he saw my sister's big firm tits! I found myself thinking maybe boys are interested in a little more than just pussy but there was no time for further consideration. No, Matt was all over Kathleen and then I saw her hand encircle his penis and she guided it to her waiting pussy. She moved his prick salaciously up and down her pink pussy lips and then Matt drove into her real hard. My big sister gasped when she felt it and then the two of them were just.
