Adam then stopped. He was looking at his naked sister on the floor. Yes she took something from him, but could he judge her at all? HE wanted a big dick, and who said his sister can't have the same desire? He knew for a while that his sister and Amy where doing a few “experiments” with others involved, maybe his sister only wanted to try it out, or have her own way with her, or the others…

He picked his sister up, and placed her into her bed. He saw his sisters body, with all of its naked glory. He started to admire it, and being so close to it was so tempting… he placed his hand, on her face, and stroked her naked frame, tempted to stop at her breasts, but got down to her cock, what he grabbed firmly. Was it real? Can it be real? Does it work at all?

Those questions started to plague his mind, until, he started to stroke it. He will find it out for her.
