She climbed up on her hands and knees to the center and then bent over with her face on the bed and her ass high in the air. She reached back and spre...d her ass for me to see the little black butt plug that had been inserted into her. “Please fuck my ass Sir,” she moaned. I didn’t hesitate and climbed up behind her. She continued to spread her ass as I pulled at the plug. It popped out and I was at her entrance with my cock almost immediately. I began pushing into her with slow easy thrusts and. I came for the first time with a woman, and without a cock, a dildo or my own fingers. It rolled through me, a wave of pleasure, an ecstasy of sex, wetness that just erupted from my pussy and I had no need to control it.

I came for what seemed like hours of. Peter told me to shut up the second time I asked."Dad..." I start again but he cuts me off."There's a chance - not a big one, but a chance - that Peter isn't Charles' biological son." He says quietly.I open my mouth and for once, nothing comes out.That's fucked up.We sit and wait for Peter an' Uncle Charles. When they come out, Peter sits next to me, but Uncle Charles calls Dad over. They talk for a minute then Dad goes back into the office.Peter looks like he's been run over which is how he's. I grew hornier. I knew that feeling. Seeing as I was hornier, I did what came naturally to me. I lowered my hand down over her ass and pressed her ass firmly and enjoyably too. She loved it. I know she did because she made noises as if it was to that effect. Proud of myself for the move, I did it again only a little more passionately. That was a good move. Her leg actually wrapped around me as we came even closer to each other. Our bodies were in heat or so I thought we were. I reached for her.
