I thought briefly of how George might have managed Casey, then quickly suppressed the thought given the things I might not have been aware of. Sure, s...e was twenty five, but I instinctively knew the experience I'd gained as a high school teacher was exactly what I needed, even if I hadn't seen a classroom for some time. I surreptitiously took a breath, then dove in."I expect you here at 9AM," I said, without looking up from my desk. She said nothing and I pretended to work for a few more. “Oh, don’t bother with that. You can both change at our house.” He sat down. “Carla’s getting cocktails ready for us now. We can drink a little first, talk, get to know each other, then go for a swim, if you’re still interested.”“Okay,” Susan said. She turned toward the stairs and I followed her up.Once we were in the bedroom, she asked, “Are you okay with this?”“Yeah,” I said, feeling a little dazed. I was just getting ready to get into her panties, and now she was double-checking with. I slid my thumb through her slit and into her opening, fucking her with it, as she stared at the sight in front of her. She started bucking her hips, my thumb fucking her like a tiny cock, and moaned as she climaxed.Betty let out a deep groan and her pussy clenched tight on my cock, buried deep inside of her, and also climaxed. Her whole body quivered and trembled as my wife's body shook and bucked, almost breaking my thumb. Moans and whimpers replaced the loud groans as their orgasms. I realised that I had been very obtuse, but it never dawned on me that they were thinking of going all the way."So you want us to provide you with a place where you can have some privacy," I asked her."Would you mind doing that, but if you think it might cause you trouble I will understand if you don't," Marjory said nervously."Listen Girl," I said, "You and Kenny are welcome here anytime. You do not have to wait for an invitation. And if we happen to go out for any reason no one is going to.
