Two young men trying anal sex for the first time.  They were experimenting and had said they would trade positions for the next time, but there is no way that is really going to happen. The top heard the bitch below him screaming in pain as his thick cock penetrated the boy’s tight virgin ass.  He knows that it must have hurt like hell.  After a few minutes the screams of pain changed into moans of pleasure, but it was the screams that stayed with the top.  He figures that the bottom is already broken in, why go thru the same thing himself.  He enjoyed the fuck from the first moment, with no pain required, and besides being on top feels right. He likes being the one in control, the one doing the penetrating. He knows he can force the boy below him to be the take his cock again. There is no reason to try another way  He figures that after he has force fucked the boy a couple of times, it will stop fighting back and accept its place on the bottom, taking dick.

There is a natural order to things, some men are born to penetrate others and some are born to meekly accept cocks in their holes for the pleasure of others.
