him standing with just a jock strap on and his shirt. Then he pulled off his shirt and stood only in his jock with the head of his now leaking cock sticking over the waist band. It really looked hot! It wasn't wrinkly at all. It was shiny, hard and purple just like mine and it was big and thick, too. He started rubbing his cock through the jock as he finger fucked me and watched me masturbate while I was watching him. We were both really getting horny and I knew I was going to cum any minute if I kept this up. "Take your jock off, Doc, I want to see your whole hard cock right now". I was going crazy with lust now. He pulled down his jock and it fell to the floor and he stepped out of it. Now he was standing in front of me completely naked with his four fingers fucking in and out of my asshole. His cock looked a lot better now that it was completely free. It was big and leaking precum all down the sides as the doctor started stroking it up and down to the same rhythm as my stroking.

"Why don't you put that big hard cock in my asshole, Doc. It looks like it will fit now that you've opened it up with your fist". The doctor immediately pulled his fist out of my asshole and moved himself into position to fuck me with his big hard cock. He was shaking with lust. He came in between my legs and touched his cockhead to my hole and rubbed it around for a little while then started to push it in slowly. Even though he had stretched my hole open with his fist his cock was so thick that it didn't go in easily and started to stretch my hole even wider. It hurt at first but as he pushed it in further and further the pain started to go away. His cock reached way up inside my asshole and started to touch my prostate every time he thrust it into me. This was starting to drive me wild and the doctor was starting to moan really loud. What if someone hears us and comes in the unlocked door I thought. I didn't worry for long because at this point I didn't care. I was way too hot and horny to care. I would probably have even liked it if someone came in right now and saw me getting fucked hard by the doctor’s big cock while I was jerking off my own big greasy cock. This was hot, hard, man to man sex at its hottest and I was really getting into it. I had no idea how hot this kind of male sex could be. My balls started to pull up against my cockbase and I knew I was gonna cum soon. The Doc was really fucking me hard, now taking full length strokes into my hot asshole. Our hips were in sync with each other. "Give me that cock!", I yelled at him. "Pump it in me harder. Harder. Faster". He reached up and pushed my hand away from my cock and grabbed it and started stroking my cock for me while he was fucking me. This was incredible! His hand felt fantastic on my cock and his hand was covered with my precum which was flowing all over his knuckles while he jacked me off.

He really started stroking me now and I figured he was gonna cum up
