My Time As A Sex Research Volunteer

[Rage24]

The ad sounded too good to be true. Seeking males aged 18 and above to volunteer for a medical study, food and lodging provided, and on top of that they are paying $20,000! And that's just for the first phase, which lasts a month, they will have numerous phases that I can elect to take part or not. However, I still have to pass a screening first. Since I've been jobless for quite a while, I really don't have much of a choice.

I arrive at the institute, called Sunshade Research, and was welcomed by the staff members, then promptly led inside. I'm brought into what looks like a doctor's office, and took a seat as they told me to wait for Dr Liu who will brief me on the details. I waited for about ten minutes and started to get fidgety, before she finally entered.



"Hi! Sorry to keep you waiting Mr Lin, I'm Dr Liu. How are you today?" said the young lady doctor, who's not in a white coat but still has a stethoscope draped over her neck. Damn it, I always get a bit nervous around beautiful women but I need to try and keep cool.

"It's ok, Dr Liu, I'm fine thanks. You can just call me Tyler by the way."

"Ah, but my boss doesn't like it haha, he prefers we address volunteers formally. You're still our guest after all. Later I kena scolding."

Wow, she's already joking and in a playful, bubbly mood within moments of our meeting. I'm relieved as it helps break the tension, but I'm still kinda tense. She settled down on her seat and started laying pieces of paper on the table.

"So, what have you heard about this particular research so far?" she asked.

"Well, I know the payout is good."

She smiled at my mentioning of the monetary incentive, and replied.

"Haha, that's true, I also wanna take part! But beyond that, anything else?"

"Hmm...it lasts for a month? And I remember the ad saying "looking for open minded individuals."

Her eyes lit up towards the end of my sentence.

"Yes! That's the key word. 'Open minded'. So I'll get straight to the point. You ready?"

I didn't know how else to respond except nodding my head a little. What should I be prepared for?

"We are conducting a research on sexual health. If you pass the screening, we will be observing your habits and taking semen samples through various sex acts, ranging from masturbation to having unprotected sexual intercourse with women who have all been screened for sexual diseases. We will be offering to you various sex health supplements that are all made from natural ingredients to see their benefits. I want you to know that all our staff members here are well trained to take care of you, and you are covered by our insurance should anything happen to you during the course of the study, and you can opt out at any moment. You following me so far?"

What the actual fuck!? My jaw nearly dropped but I didn't let it show. She pretty much lost me after the part about masturbating and having sex. I couldn't even nod in affirmation this time, and she noticed.

"Mr Lin? So did you get the gist of what I just explained? Do you need to clarify anything?"

I don't know where to even begin. I'm completely stunned. She smiled again, as she put the papers together and put them in a file.

"It's ok Mr Lin. You can take these papers back to read the details and consider. If you do agree to participate, I'll see you again here next Monday. Is that fine with you?"

"Yeah, I'll give it some thought. Thanks."

I left and tried to read those papers on the train home, but was worried that other people would stare into the weird sexual details and had to continue reading at home. Those lanjiao papers were still very cryptic, never properly expanding on what they actually mean but using words like "gain a deeper insight of the subject's sexual quirks and fetishes through behavioral observation" bla bla bla. But the last page once again emphasized on the $20,000 payout which can lead to even more. Damn it, just hoot la.

The following Monday arrives quickly, and I am back in Dr Liu's office. I waited a few minutes for her arrival, and she looked very glad to see me.

"MR LIN! So happy to see you again! So you're willing to take part?"

"Y-yeah, I'll see how it goes. Can opt out anytime right?"

"Yes! Of course we hope to have you for the entire study, but it's your choice, always. So, let's get started with the screening, shall we?"

She sits down and brings out a tablet and opened up what looks like a questionnaire.

"I'll be asking you a series of sex related questions. I want to assure you that all your answers will be kept strictly confidential, but I really hope you can answer them all truthfully so you stand a better chance of being selected for the study. You ready?"

"Err...ok."

"Okie dokey...first question. Are you single or in a relationship?"

"Single."

"Are you a virgin?"

Whoa, second question already quite invasive!

"Umm...no."

She noticed I'm kinda tense and touched my hand.

"Relax Mr Lin, I want you to know that there's nothing to be embarrassed about, and the more open you are with us, the more it would help with our research."

She moved her hand back to the tablet.

"When was the last time you had sexual intercourse?"

Walau! That was so long ago. I'm a bit paiseh, so I said three months, when in reality it's closer to a year. But she's so damn good, one look at my face and she knew something's amiss.

"Hmm...three months? Confirm?"

"Uhh...wait, I think closer to six months. Time flies haha."

She smiled, but I peeked into what she typed into the tablet. She put one year! The fuck, she's like some sort of psychic. I know I need to be really honest now or she'll keep pulling these stunts and make things awkward.

"Was it with a sex worker?"

"Y-yes."

Shit, I folded too easily. But she didn't even bat an eyelid, which made me more comfortable in being truthful.

"Did you wear a condom?"

"Yes."

"Very good Mr Lin, you're a responsible patron."

The fuck...this doctor is actually praising me for calling chicken. Now I'm really quite comfortable with answering.

"When was the last time you masturbated?"

What a question. I don't like this is going.

"Um...this morning."

"Did you masturbate while watching porno or through your thoughts?"

"Uh...I...fantasized."

"Understood. What did you fantasize about?" she asked, smiling.

DIE! My heart raced at the question and I started tapping my feet. I keep stalling, but could not force the words out of my mouth. She finally put me out of my misery.

"Were you fantasizing about me, Mr Lin?" she said with a straight face. I'm embarrassed like mad! But she once again put her hand on my arm. I gave a meek "uhh...y-yeah."

"It's ok! Nothing to be ashamed about. I'm honored haha." was her reply, as she attempts to make me comfortable again to coax truthful but embarrassing answers out of me.

"What made you fantasize about me? Was it my looks, figure, personality, or the fact that I am a doctor?"

"Yeah, mostly the fun in fucking a doctor. But of course, you're pretty too. And you have a fine figure. And a great personality."

"Thanks Mr Lin. So, was your fantasy of having sex with me set in this room as well?" she continued. I'm just gonna power through now.

"Yes."

"So explain to me what happens. Try to be as detailed as you can Mr Lin, including specifics of the actions and dialogue. It would really help us."

I take a deep breath, and started speaking.

"Well, I fantasized about rubbing my hand on your thighs, then reaching in to grab your crotch. You said that as a doctor, you needed to de-stress, and we started to undress each other. I...ripped apart your blouse, hiked up your skirt, yanked down your panties. Then you willingly bent over this table and said "fuck this horny Doctor Liu!" and I...jammed my cock inside your vagina."

I said all this while she diligently typed everything into the tablet, with a faint smile on her face. I got so hard not just from reliving my fantasy, but from the arousal of actually telling it to the subject of my arousal!

"And did you ejaculate inside my vagina?" she continued.

"No. I...er...I pulled it out, then jammed it inside your anus."

"Changed to anal intercourse..." she murmured as she typed what I said into formal terms. "And that was where you unloaded your semen, inside my anus?"

"Well, yeah, but in my fantasy I had a lot of semen so I covered your body and your face with it as well."

As she typed, I ghey kiang and added.

"By the way, it's not the first time I've masturbated to you...I also jerk off to your instagram pics."

Nice story.

[Rage24]

"Interesting! Are you able to show me which ones?"

This is so unusual, typically I would expect a slap to the face if I told a lady that I masturbated to her pictures, but this Dr Liu seemed genuinely intrigued and eager to find out. I took out my phone and went to her instagram page, pinpointing to her the pictures that made my cock rock hard. She's quite conservative and it's not easy to find photos of her showing a lot of skin, so to think she's a sex researcher is quite mindblowing!



"This one, Dr Liu...I...came about three times."

"Haha, that is a pretty good pic! What did you fantasize doing to me in that swimsuit?"

"Uh...I imagined just shifting the fabric on your crotch and then just fucking you from the back on that float."

"Mm hmm. And how would you describe the load of your ejaculation, and the high you experienced...was it better than normal, average, or lesser?"

"Definitely better than normal! I mean...I get a kick out of masturbating to women I know in real life, compared to say pornstars. I'm sure most guys do as well."

"Understood. Ok, Mr Lin, now that we have established your current object of sexual fantasy, can you do me a favor and provide me with a semen sample?"

I'm stunned, totally not expecting that!

"What? You mean...right here?"

"Yes Mr Lin. Like I said, no need to be shy with me. I will help you, so just remove your pants and leave everything to me."

She put on rubber gloves and reached into her drawer for a cylindrical shaped contained to deposit my semen. I slowly get up from my seat and stood up, then unbuckled my belt and pulled down my jeans. Well, I guess this is it. I pulled down my underwear as well to show her my exposed penis, already erect thanks to our erotic conversation.

"Wait wait wait Mr Lin! Sorry I forgot something!" she exclaimed, before taking out a tripod to set up her phone, then video taping the whole thing! "We need to document the penis from erect to orgasm and post orgasm. Don't worry your face won't be in it."

She wheeled her chair forward and touched my cock for the first time, then felt it's thickness and firmness, lifting it up to inspect my balls and practically scrutinizing every inch of my genitals. It's so erotic yet she seemed totally engrossed and professional.

"You're very healthy, Mr Lin! Now, time to start."

She brought out a bottle of lube and squirted a small amount on her hands, then slowly grabbed my dick.

"Abit cold ar Mr Lin, everything still ok?"

"Ya, it's fine." I replied, as I turned my attention to my phone that still had her swimsuit pic on. Dr Liu cups my testicles with her left hand and massages them slowly, while her right hand starts stroking my shaft, and it's amazingly sensual. It feels so surreal that she is actually masturbating me looking at her pic! But my attention slowly drifted to her in person. Even though she's all covered up in formal attire, it feels so much more arousing looking at her giving me a handjob. She picks it up quickly that she herself had become the object of my arousal.

"Mr Lin, would it help if I raised up my skirt and let you see my panties?"

[Exvacating]

Dr. Liu very automatic
