Adam doesn't expect a reply anytime soon, so he begins to think about what just transpired in the changing room.
He saw Sean and Ellie having sex. Well, Adam doesn't know if he would call it sex because it was really pathetic.
Not Sean's dick size. There is nothing wrong with having a four-inch dick. He has heard conversations with numerous escorts, and they did tell him some of their clients were really good with it, even though they were not gifted with size.
And they had no reason to lie to Adam. Even though he was not as big as he is now in his past life, it was a respectable six inches in size, just an inch away from being considered big.
But that's not the point here. What he saw Sean doing was actually pathetic; he moved like a stiff board, just going back and forth. No technique was involved in it, and it was evident on Ellie's face as she had no expression on her face.
