It's very natural for men to take ass. Doesn't have to be rough either... just bend over and let a real man in your faggot ass... you'll learn to like it.
Yeah. That's why they should've done it for real. Just stick that dick deep in the ass, so that his facial expressions come naturally. They are professional actors, their job is to make it believable. If they can't act it out, then take it up the ass!
