Billy grabbed her nipple again and viciously twisted it. He pulled up until it would stretch no more and then he let go. Then, he reared back and sl...pped the side of her tit hard. Her tits bounced, recoiling from the strike.Suddenly, Billy moved back, pulling his cock out of his mom. “Get on top,” he told her. He fell onto the bed next to her, on his back.Carole unfolded and threw her leg over him. Straddling him, she lowered herself onto his big cock. “Oh, God, yes,” she moaned as she. She claimed it was easier to do it in the nude than clothed. I thought differently, with a hard cock that kept getting in the way. Still, Miss Steinberg was quite a looker, and of course Madison was too. Having those two doing splits and rolls and other gymnastics feats all period got me hornier than a pit bull in heat.Once class was over I headed to the locker room. Before I entered, Madison approached me"You look pretty hard there," Madison said seductively."Yeah, well watching you and Miss. “What?”“Your dick,” she said and looked around guiltily. “The way it moves by itself. It’s kind of like it won’t move on its own, but the sun powers it. It’s a solar powered dick,” she got a big kick out of her own joke. “I can think of times when it would be nice to have a sunlamp,” she snickered.I looked down. I had felt it. It wasn’t erecting. I’d noticed it years earlier and never paid attention any more. But as we both studied my cock, it did start to fill out. I wasn’t erecting, though. "Your mom and I thought you should try thisdress on first, to show you the difference in fit with your new"girls"!" She handed me a green sleeveless polyester and spandexpullover style wrap dress, with a plunging neckline and thin shoulderstraps. I took the dress from her; Tiffany held me by the shoulder as Istepped into the dress and pulled it up my body. The sensation of thefabric brushing against my silky tights was intoxicating... I had totug and pull the top of the dress in order to.
