... withdrawing halfway and slamming back in, needing more of the addictive sensation, quickly building up his pace until he was painfully jackhammering into me, holding me facedown with his powerful arms as he railed my helpless cunt.

I couldn't get enough of the pain. The sex was so much rougher than anything I had experienced before, but in my current state I wanted nothing more than to be held down and brutally used. I wanted him to force me to receive his seed, to prove that he was the one who deserved to breed me.
