hole and then I felt a third finger join the other two. I thought this was going to hurt but it didn't. I was just laying there letting all this happen because it was feeling so good. I didn't stop to think about what I was doing with this doctor. Then I leaned up on my elbows and looked down to watch the doctor and he was very intense and his mouth had opened up a little as he was playing with my nuts and asshole. He had a very lustful look on his face. He looked up at me almost meekly like he knew he couldn't stop what he was doing because he was too horny himself.

"I am really getting turned on looking at your balls and fingerfucking you. Does it feel good"? I nodded to him. He had no idea how good it felt. I felt my hips start to move with each thrust of his fingers in my asshole and my cock was now flowing with precum. The doctor stood up and moved in closer between my spread legs so he could fuck my asshole with his fingers better. He added the fourth finger which I figured was coming at any time and I almost wanted it! My hole was practically sucking his whole hand in. The doctor was drooling now while looking at my hard cock and I reached down and pushed it away from my body down towards my balls. It wouldn't go very far because it was too hard but it was standing straight up now and the precum started flowing down the sides. I couldn't help myself, I had to jerk off. I didn't care if I was in front of another guy at this point. Besides this other guy was fingerfucking me like crazy while he was pulling on my balls. He was completely lust crazed as he watched me start to stroke my big hard greasy cock, up and down in long slow strokes. The stirrups had my legs splayed wide open and it felt great. I could pump my cock into my hand by pushing up my hips and into the doctors fingers in my asshole.

This was really getting very hot and horny. I could smell the sex from my crotch and the doctor was moaning while watching me jack my cock. He leaned over my cock while I was stroking it and stuck out the tip of his tongue and touched it to the head of my dripping cock and he licked off a big drop of precum. His eyes had glazed over and he was acting like he was so horny he was out of control. This really turned me on knowing my cock and balls and asshole were turning this old guy on. I looked down at the doctors crotch and saw his hard cock in his pants and a big wet spot where his precum was leaking out wetting his pants. For an old guy he sure had a big looking cock. Would it be all wrinkled as I imagined. I had never seen another guys hard cock before and certainly not on a guy who was fingerfucking me and licking my cock!

"Take your cock out Doc", I said. I couldn't believe it was me saying it but I really wanted to see this old guys hard cock. He took his hand off my balls and reached down to undo his zipper and open his pants. He pushed his pants down and stepped out of them leaving
