Basically, we started off with polite small talk and gradually escalated to full on dirty talk about what we wanted to do to each other. Most of the s...uff we wouldn't or couldn't actually do, but for three days while we were both at work, we talked and masturbated over instant messenger. It was simply amazing listening to my wife's sister, who in our family settings is very conservative and clean cut, tell me things like she wants me to finger her ass while she sucks on my cock. It's. Now she felt his cock lurch under her and it began to poke against her stomach. "Would you like some more?" she asked while looking back over her shoulder. In answer Mikes cock jumped to it full length and his eyes got that same glazed look that Jade was getting herself. "Ok, lets see how you like this" and she grabbed hold of his cock with both hands and started to lower her ass down onto him. Mike couldn't believe his eyes as he saw first the thick mushroom head of his cock probe the tiny cum. I think she knew better and I know Gina did, but she still asked. She seemed a little uncertain, and with a moment’s thought I realized that it was only half about me. Gina really had “seduced” my best friend. A story I would get out of Gina later. “It just kinda happened. I was going to tell you, but Gina wanted to make it a surprise and…”“Do I look mad?” I leaned in and kissed first her and then Gina. “I’m thrilled. Don’t you know how long I’ve wanted to get between your legs?”“She knows. She. "Suck my tits, Mel suck on my hard nips babe," I told her."Ommnnghhhh," The Vice Principal moaned as she sucked my heaving breasts with one hand under my bra to support them she found my panties and pulled them down and fingered my wetness.We caressed each other for a few minutes and then I went down on her lovely pussymound. Mel sat in the bench stall as I pulled off her panties and dove my face into her modestly hairy mound. I stroked her warm labia, parting it with my experienced tongue as I.
