My name is Kiko and I was responding to an ad I found in the paper for a new medical drug that pays $1000. When I went in I met Dr. Rimmerman who was helping with the study. He took some of my history information down, and explained to me that they just recently changed the drug to make you horny right away. He gave me a small dose of it, and then let me wait around for a while to see what affects would take place. After stepping out the room for about 15 minutes, he returned and noticed that I had a big boner. We pulled my pants and the doctor started to examine my penis. He pulled my underwear down and really started to jerk me off. Then, he proceeded to start to give me head and lick my cock with his tongue. Actually the doctor was very talented at giving a blow job. He asked me questions as he jerked me off, and wanted to know if I was horny enough to give head. I had never touched another guy before, but here I was getting paid for this study and this was a doctor. I stood up and got undressed and then the doctor did the same thing only he sat down on the bed spreading his legs wide open. He sat back as I lowered my head down to his cock and started to suck on it. I tried to mimic how he gave me head so I would do a good job. We both laid down on the bed in 69 style and continued to give oral to one another. It felt great to have my dick serviced and he was doing a better job than my girlfriend. The dock had a pretty good size penis that took up my whole mouth. Oral went both ways switching back and forth and then the doctor had me scoot back on the bed a ways. He spread my legs apart and started to lick below by balls to my asshole. It felt so good! I started to fuck his face, because his tongue inside my hole felt so good. He bent me back and then used his tongue to lick my hole. I wanted to pay the doctor back for doing that and so I gave him head once again and jerked off as I sucked on the tip of his penis. After a while I got up on my knees and jerked off in front of him. I didn't know which one of us was going to cum first, him or I. However, before I knew it I had an orgasm and sprayed my cum all over his lower body and cock. With my load on the doctor, he then was pooped and he got up to get me a rag. That was one of the weirdest way I have ever made $1000 bucks, but it was fun and I hope my girlfriend never finds out.
