"Please don't hit me," he almost whispered it. His cock began to stiffen as he waited for me to decide what to do. I sat on the bed and pulled him over my lap. I felt his cock rubbing my thigh while I stroked his ass. I began to spank his very willing ass with my bare hand. The harder I slapped his cheeks, the harder we both got. After a few dozen whacks, I instructed him to kneel and open his mouth.
"Suck me till I'm hard as a rock." He sucked me. He licked me. He ran his tongue up and down my shaft, twirled it around my cock head, licked and sucked my balls.
"Get on the bed on your hands and knees."
I squirted some lube into my hand and rubbed it on his asshole. I managed to somehow get a condom on my hardon. The rest of the lube was smeared on my erect, blood engorged cock. I crawled up behind Mark and tested the tightness of his hole with my fingers.
"You feel pretty loose," I said as I fucked him with my fingers. I pulled them out and pressed the tip of my cock against his little pink hole. I pushed a bit harder and Mark grabbed the comforter and squeezed. I withdrew my cock tip and rubbed it all around his tight ass. I slowly pushed my head into his back door and the whole head disappeared into his dark place. Mark began to moan in either pleasure or pain, I couldn't tell which. I pushed another inch into his asshole and he began to whimper and growl. About half my dick was inside him.
"One more push and my whole cock will be in your ass."
"Fuck me Tommy. Fuck my asshole."
I obliged him. My final three inches slipped right in and my cock was gone. I withdrew it and shoved it back in. Over and over, faster and faster, in all the way and out. I began to pound him harder and quicker. His hips began to to coordinate with my thrusts, until it was like one motion created between two people. I was digging my nails into his hips, pounding my best friend's asshole like an animal.
Mark growled and balled his hands into fists while I raped his ass, sodomised his asshole.
"I'm gonna cum. Be ready."
