We were on our third day of me having my way with Mark. So far, I had fucked his ass nine times, cumming inside him seven times, shooting my wad on his ass twice more. He had sucked my cock five times, swallowing the load each time and he had been allowed to cum five times.
It was now three in the morning, I had gotten up to go take a leak and came back into my dorm room, and saw his perfect ass spread wide open, his legs still tied spread eagle on the bed. His hands were still tied to, exposing him completely. I reached down and gently rubbed his beautiful ass, he moaned and asked, "Are you going to fuck me again?"
I grinned to myself and asked, "Do you want me to?" Slipping my fingers between the globes of his ass, my middle finger teasing his hole.
"Either that, or," he hesitated, "or, fuck my mouth again."
I smiled and said, "I've got an idea." I then reached over to my desk and opened the drawer, pulled out a seven inch dildo. The dildo was about two inches round and curved just like a real dick. I grabbed the lube and slicked the dildo up, then I applied some lube to Mark's ass crack and pried his hole open just enough to squirt the lube into his butthole.
I slowly worked the dildo deep into his ass, inch by inch it disappeared into his butt.
"OH! OH! That's fuckin' awesome!" he groaned. "It's huge! I love it!"
Soon, the full seven inches was in and I began to pull it out and shove it back in. First only an inch or so, then two, then three. Now I was pulling it a full six inches out and ramming it back inside his ass, with each thrust he screamed into the pillow under his face.
I now had the dildo buried completely in his butt. I grabbed the duct tape off the table and tore off a six inch strip. I then taped the dildo in place, using his round butt to anchor the tape down.
I walked around to the front of the bed, lifted his face up and slid the pillow under his chest so that his face was raised up. His eyes were shining and he smiled, opening his mouth as he saw my fully erect cock pointing to his lips. I slid inside his mouth, grabbing his hair and slowing moving forward. I felt the tip of my cock hit the back of his throat and he tried to gag. I didn't pull back, I pushed harder, holding his red hair tightly in my hands. I kept pushing, he kept gagging. Spit and slobber was pouring from his mouth as he gagged more and more. When I felt his lips touch my pubic area, I began to pull back and let him catch his breath. I then rammed my cock back in, followed by more gagging and much more slobber. Tears were streaming down his face as my cock continued to bang back and forth in and out of his mouth and throat.
I continued to ram my cock down his throat until I couldn't last much longer. I pulled out and blasted my load all over his face, coating his eyes, nose and mouth. I wiped my dripping cock up and down his face until it was drained completely.
"Thank you! Thank you! I love your cum, I love your cock," he moaned.
I squatted down on the floor in front of him and kissed him deeply. I could taste my cum in his mouth, and the slobber he'd been coughing up. After kissing him for several minutes, I stood up and removed the ropes from his hands. I then freed his legs, leaving the seven inch dildo taped up his ass. I had him stand up on the bed, facing me. I took his five inch rock hard cock into my mouth and began to bathe his balls and shaft with my tongue.
"I can't hold back," he exclaimed, "I'm gonna cum soon! Oh shit!!! Here it comes!!"
