When I started college, I took Psychology 101. All new psych students were required to fill out a long questionnaire, and based on our answers, we were assigned to be subjects in experiments. The experiment I was assigned to was sexual, checking out male sexual response to homosexual stimuli. I reported to my lab room, where I was told I would be sucking the cocks of three straight guys every day over a a one week period. The test was to see if they would become more comfortable with being sucked by a guy, and if they would do more than they indicated in their questionnaires. Each subject had said he would let a person of the same sex suck him as long as he didn't do anything else. The first day, I was suck them, without touching them on any part of their body except their sex organs. They would be blindfolded and would not know who I was. I was chosen to suck them because I indicated on the survey that I was gay, and would be willing to do it with anyone in the class.
When I got to the testing room, the first student was there. He was blindfolded, and fully dressed. He was an Asian guy, about 18, thin and smooth. I told him to stand up and drop his pants. He unzipped his jeans, and pulled them down with his boxers, and i got my first look at him. He had long black pubes, smooth thighs, and a soft, 2 inch cock. I sat in front of him and played with his balls. His cock started to grow and harden. He had a six inch cock. I breathed in his scent, and swirled around the head with my tongue, after which I took his shaft in my mouth and sucked him off as I gently played with his balls. A few minutes later, he shot his load in my mouth. I told him to get dressed, and when he heard me close the door, he could remove the blindfold. I told him to be here same time tomorrow. I left the room, and soon he did too. I filled out the report I was required to, and waited for the next subject.
Twenty minutes later, I heard the next subject come in the room. I entered, and found him sitting down, wearing the blindfold. He was an Indian guy who lived in my dorm. I told him to stand, and take off his pants and underwear. His body had a light scent of curry, and he was very hairy. I wanted to feel his hairy legs and stomach, but I was not allowed to. I pulled back his foreskin and licked his head, and sucked his growing cock. He was much bigger and thicker than the Asian, and I enjoyed sucking him. He shot in my mouth, and I swallowed. I gave him the exit instructions, and told him to be back at the same time tomorrow. I filled out the report, indicating the basic sexual response to the stimulus.
Twenty minutes later, I met the third student, He looked and smelled like he hadn't bathed in two days. I told him to take off his pants and underwear, and soon I had his big hairy cock hanging in front of me. He had a cocky attitude, and I reminded him that his instructions were to not disrespect me in any way during the tests. He apologised and said he was nervous. I could see that his blindfold was on tight, and his hand was shaking. I took his big low hanging balls in my hand and gently pulled on them. He sighed. I held his cock and stroked him a few times. He grew in my hands, and I took him in my mouth. I started to deep throat him, and could feel his cock down my throat as i buried my face in his pubes. He moaned loudly, and I felt his cock throbbing in my throat as he shot a huge amount of cum down my throat.
We repeated the assignment the second day.
On the third day, I went into the room and met the Asian guy. His blindfold was on,and his pants were down. His cock was hard. I asked him to take off all his clothes. Without hesitation, he stripped naked. Instead of just sucking him, I started to feel his chest and pits, and massage his inner thighs. He yielded to my every touch. I got between his legs and sucked his balls and licked his perineum. My hands roamed his body as I sucked his cock. He started face fucking me, and shot his load in my mouth. He was shaking when I was done. I told him to get dressed and I would see him tomorrow, same time. I went in the office and filled out the questionnaire.
Twenty minutes later, the Indian came in. I told him he needed to strip down, and i watched him take off his clothes. He had a beautiful toned hairy body. I ran my fingers along his hairy chest, I told him to put his hands behind his head and I started to lick his pits, I felt his hairy thighs, as I sucked on his hairy balls. He let out soft moans of pleasure. His cock was dripping precum and I took him in my mouth and sucked him as I felt his hairy ass cheeks. It didn't take him long to shoot his load inside my mouth. He thanked me, I told him to get dressed, and be back tomorrow, same time. He asked me if i liked doing this,and I told him I did. He said he did too. I went back in the office and reported that subject # 2 was compliant.
Soon subject # 3 was in the room. He had his blindfold on, but fully dressed. I asked him to get undressed. he asked if it was part of the experiment or if I just wanted to see him naked. I told him it was part of the experiment. He said he didn't want to do it. I said he didn't have to, but if he didn't I would have to report it. He grumbled but got undressed. he had an average body, no real muscle tone, but I started to massage his shoulders. He said it felt good, and let me do it. I told him he had a nice chest, and he let me run my hands along it. I started to massage his thighs, and he got hard. I sucked his cock, and he shot his load. He got dressed, and left. I reported that subject # 3 was uncomfortable with the program.
Day four went as day number three went, except that subject # 3 was more cooperative, and let me give him a full body massage.
On day five, I was instructed to get undressed as well. My subjects were now waiting for me in the room naked when I arrived, with nothing but their blindfolds. When my Asian subject arrived, I entered the room naked, and started to feel his body. He brushed my chest with his hand, and when he realized I was naked, he started feeling me as I felt him. Noticing that I'm a chubby guy, he started feeling my breasts, and he asked if he could suck them. I told him he was allowed to explore my body all he wanted. He felt me all over and stroked my cock. We lied down and he stroked me and fingered my ass as I sucked his cock. It felt really good, and I started to moan. He stroked me faster, and made me cum. I finished sucking him. and told him same time tomorrow. In my report I indicated that when i undressed, subject # 1 brought me to orgasm.
When the Indian student came, I entered the room naked. He was naked except for the blindfold. As I started caressing his body, he felt that I was naked. Before I could say anything, he was feeling me all over. I was hard again, and he had lay next do me on the bed. He did everything I had done to him previously. He massaged my breasts and sucked them. He said they were as nice as a woman's. He licked my pits, and started sucking my cock. He got on top of me and kissed me. He said if I was a woman, he would fuck me. I told him he could if he wanted. I helped him put his cock against my hole. He was leaking so much precum, it wasn't long before he started to slide into me. He fucked me long and slow, then faster. I could feel his cock throbbing inside me. He said he never knew sex with a man could feel this good. Before I could say anything, He shot his load in my ass. We got up, I told him to come back tomorrow, and he got dressed and left. I reported that subject # 2 initiated man on man sex.
I douched and cleaned up, and got a message that subject # 3 would not be coming in. I reported that subject # 3 failed to show up.
The next week I was called into the professor's office. He told me that subject # 3 was arrested for raping some girl off campus. The test was a success, and I and the other participants would receive A's. He was impressed that I was so professional, and offered me a position as his assistant, which I agreed to take.
After class the next day, the Indian student started walking back to the dorm with me. He said he knew it was me in the tests, and I told him it was. He said he couldn't get me out of his mind, and was wondering if I was seeing anyone. He said his roommate was going to be away this weekend, and was wondering if I would like to spend it with him. I asked if he wanted to do more experimentation. He said no, this is just to enjoy each other.
