A lot of girls do it under the condition to teach how to do it. The girl looks, but she doesn't know her own words, or her dick. Turns out it's hard to satisfy a cock in the ass. He has to find out whether that cock is ready for the quest. She goes on top, the girl gives him a naughty blowjob, and then, it's the turn, the chick penetrates the guy from behind and ends up cumming on the guy. Well, we say on the nose!
