After our initial kiss he looked down at my t-shirt tits. I knew he liked my tit thrust in the thin t-shirt and the way my nipple pokies protruded.I l...d him into the living room and we sat on a sofa. I moved close to him, placed my hand on his left thigh, and then moved my hand to his dick. I touched it through his pants. It was already hard.I told him to take off his pants and sit back down next to me. Wet spots had already begun to stain his underwear. He once told me he would usually get so. I heard the water slosh again, and assumed Michelle was getting out of the tub. "Dad, Dad, can you come here?" She rarely called me "Dad," as I was her step-dad. I figured it was fairly serious. I went to the bathroom, and Michelle was standing outside the tub - holding her leg. "I can't walk on it" she declared. Now, understand, here was a nicely plump eighteen year old woman - dripping wet - and naked as a jaybird. Lovely, to be sure, and I felt a bit of a man-twinge between my legs. I went. I was so turned on with what Sara was doing to me and the thought of what my wife was doing to Tom, that it didn't take long before I was shooting my load deep in her mouth and trying hard not to swerve off the road. "Wow; that was amazing." I told her "You do it almost the same as Pam. Just fucking amazing. And I must say you look great with my cum on your lips." "I knew you would enjoy that," she said. She began to finger herself again, so I reached over and fondled her firm breast and hard. While he massaged my tits, I’d reach out and take his shaft in my hand and begin pulling on it, watching it grow bigger and longer as I tugged on it. After a few minutes of this, he’d put his hands on my shoulders and push me down to my knees. Then he’d twist one hand in my hair at the back of my head and pull my mouth toward his erect cock. He’d shove his prick forward into my mouth while pulling my head down with his hand, and begin roughly face-fucking me so that his huge dick was pumping.
