I didn't exactly jump straight to this conclusion. I had to do my research, and thankfully we live in an era where "research" material is only a click away.
I kept studying until I came to the conclusion, that cum is not the end of an orgasm. If it is done right it is an extra special horny little memory that keeps you coming back for more.
Want to see what I mean? Then follow me inside. But first, please free him, I can see him straining against your trousers. Feel free to get completely naked, but at least take your pants off and follow me inside.
