The other day I was surfing the web when I came across an ad that piqued my interest. Our local university was looking for participants in a sex research project:
"We are looking for athletic males in their twenties to participate in a sex research project. The participant's sexual orientation must be strictly heterosexual with absolutely no interest in any homosexual activities including gay pornography. The study will answer the question of whether strictly heterosexual males will engage in homosexual activities under the right circumstances. Participants must be willing to engage in any activity asked of them except activities that cause physical harm. The study will be performed onsite and participants must be willing to spend time at our research facility."
The ad listed a link where you could apply. This sounded very mysterious and definitely spoke to my inner exhibitionist. I filled out the application form. It asked me all kinds of very personal questions like whether I worked out, whether I was circumcised, what my penis length and girth were, limp and erect. They also asked about my sexual history and my porn viewing habits. Filling out the form made me very horny and I had to masturbate just thinking of what the study would be.
The following day I received an email inviting me to the research lab. I showed up on time and was let into a small lecture room by a young bookish but somewhat attractive research assistant who introduced herself as Anna.
"Frank, please sit down, we have to go over a few things."
I took a seat and waited nervously for the questions.
"You know what the study is about. We are trying to find out whether men, who identify as heterosexual only, under the right circumstances will engage in gay sexual activities. Have you ever had any form of gay sex, have you given or received from another male a kiss on the lips, a handjob, blowjob, or anal sex."
"No, never."
"How about a circle jerk without touching another man's genitals."
"Nope."
"Do you watch any gay or bisexual pornography?"
"No, I don't."
"When was the last time you had sex?"
"Uhm, right now I don't have a girlfriend."
"OK, when was the last time you ejaculated?"
"Two days ago."
"What did you do?"
"I masturbated watching porn."
"What's your favorite porn?"
"Teenage lesbians and threesomes with two girls."
"Of course, here is your consent form. Please understand you are agreeing to do anything we say unless it causes you physical harm. You also consent to all sessions and research activities being filmed."
She handed me the form and a pen and I quickly signed with trembling hands.
"Excellent, let's get started. Frank, please remove all of your clothes and sit down again. I will put a plethysmographic device on your penis. The sleeve will measure blood flow to your penis and tell us if you are getting aroused. I will then tie your arms and legs to the chair so that you won't be able to touch your genitals. We will show you videos and measure your arousal. The entire session will of course be recorded. Any questions?"
I started to take off my clothes. As I pulled down my underwear I realized I was getting an erection.
"Sorry about this," I mumbled totally embarrassed.
"No worries, happens all the time," Anna assured me.
I sat down on the chair and Anna kneeled down in front of me with the device sleeve. She grabbed my cock and wrapped the sleeve around it. Precum was starting to drip from my fully erect cock. Anna unceremoniously grabbed a tissue and wiped off the precum. She then connected the wires of the sleeve to a monitor. Finally, she strapped my hands and legs to the chair with leather straps.
"We are all set. Sit back, relax, and enjoy the show. The first show is a boring news show. We need you completely flaccid to get a baseline reading, after that we start to measure."
Anna left the room.
The first video was indeed a boring news show. It dragged on and on. I for sure was as flaccid as I could get. Then the screen changed. A young shapely coed in a locker room was slowly taking off her gym clothes. Completely naked she went to the shower and began soaping up. A second gorgeous coed showed up, took off her clothes, and joined the other in the shower. Soon they were soaping each other up, kissing, and fondling each other's large pointy breasts. They rinsed off, dried each other with towels, and retired to a bench. Here they began massaging each other and finally one was lying her back while the other parted her legs and slowly started licking her mound. The groaning became louder and louder, and then a scream and a shudder and they both collapsed on each other.
I was rock hard with no way of reaching my cock. My cock was pulsating, drooling, with no relief in sight.
The screen changed again, back to the boring news show. Again it went on and on until I was completely limp again. What's next I thought.
Suddenly again, the scene of a locker room. This time a young athletic male in workout clothes began to undress. He was muscular, well hung, and toned. He went to the shower and began soaping up fondling his rather large uncircumcised cock. A second guy showed up, started to undress. He too was very athletic, the same age, not quite as endowed. He joined the first guy. Soon they were soaping up each other, their cocks slowly rising. The fully erect cocks were poking each other and jousting while they were kissing each other passionately. They rinsed off, drying each other, moving on to a bench. The well endowed one on his back, the other one between his legs, sucking his large member into his mouth. The moaning became louder and louder, the guy's body began to shake, he pulls out his cock from his buddy's mouth and shoots a giant load on his chest.
The scene was the mirror image of the two girls. Except, it didn't do anything for me, nothing at all.
The light went on and Anna came back in. She took off the straps, slid the sleeve off my cock.
"You did well, Frank. Please go through this door into the next room. I'll bring your clothes."
I went through the door and found myself in the room with two other naked guys. We looked at each other uncomfortably. The door opened and Anna and another woman came in. She was in her late fifties with a well-toned body. Giant tits restrained by what must have been an industrial-strength bra were pushing against a tight white blouse, nipples clearly visible.
"I'm Professor Hall, leading this study. You did very well. Of all the test subjects you were the only ones showing absolutely no arousal watching the gay video scene. That means you are completely heterosexual. The next step in the study is for you to abstain from any sexual activity for one week. We need to make sure you are very excitable when you come back. To make sure that this happens we will put you in a chastity device. Here it is, a clear plastic tube in which you insert your flaccid penis. The tube is then secured into slots of two plastic half rings. The half rings go around the base of your scrotum and penis, they snap together securing the tube containing your penis. That way you will not be able to touch your penis. The tube has a hole in the bottom so that you can urinate freely. You will wear this device for one week."
While she was talking I just kept staring at her fabulous breasts. My cock started to rise to full attention. I looked at the other two guys. They too were fully erect.
Professor Hall, realizing our stares, with a smile remarked:
"The chastity device can only be locked in place when your members are flaccid. So this won't work. Please go back to the offices where you watched the videos, then calm yourselves down, put your flaccid members in the tube. Anna will then secure them with the half rings."
She turned around and left.
We went back to our rooms and the boring news shows were back. I went limp immediately, almost fell asleep. I shoved my limp dick into the plastic tube and pushed the call button next to the chair.
Anna came into the room followed by Professor Hall. Professor Hall stood behind my chair, Anna quickly kneeled down in front of me and with an expert grip grabbed my balls and the tube. She quickly snapped the two half rings in place.
