I bent under him rhythmically without even realizing it, and only after a while did I start to do it on purpose, because it was a good feeling. I reached out and touched his ass, and he reciprocated by feeling my breasts. I had two full handfuls of his beautiful ass, and as he moved on me. I had a hard clit in my panties, a hot pussy tingling out of my lips. As we moved together, he kept riding after him all that long thing. That made me wild. Then he put his hand on me and stroked my knees on my thighs on the way to my clitoris, until I almost immediately made it.
So this is what adult sex really looks like, I thought. This is the real thing, stepsiblings in love.
