I walk through the hallway and hear LOUD screaming and moaning coming from my step-brothers room. I am kind of scarred for life and I walk away. Later, I peek in to talk with him. I tell him that there is NO WAY these girls are actually cumming that hard and I know for a fact that they're all faking it to make him feel good. He insists that it is real orgasms and that he does a lot of foreplay before hand to "warm them up". I tell him to do some of that stuff on me and prove to me that these girls are actually cumming THAT hard. Sure enough, he was right. He was such a good lay, that I let him cum inside me.
