I'm continuing a format where my thoughts and feelings are enclosed in ( ).
Elvira at the CFNM Guest House gave me a call. She said I might be interested in being a volunteer subject for some friends of hers at the SRI Institute. I called them up and made an appointment. It was going to be an all-day session. I received a letter detailing the pre-research protocol. Today I head to the Institute.
I walk up to the front door and ring the bell. It opens and a red-headed female appears. "You must be John. I'm glad you volunteered for the research. I'm Ann, the assistant researcher. Please come in."
I enter and follow Ann down the hall. "Please sit down. Do you have any questions?" Ann says.
"What does SRI stand for?" I ask.
"Sexual Response Investigation," she replies. "Here's the one piece of paperwork you need to sign. It's the volunteer consent form."
She hands me a piece of paper with really small print. I glance at it, sign it, and hand it back.
"Excellent. So, let's get you prepared. Here's a gown. Please remove all your clothes and put this on. I'll be back in a minute."
I take the paper gown and put it on the table. I remove all my clothes and place them on the table. Then I put on the gown. It's short. It barely covers my rear and balls. Ann comes back.
"That looks good on you. Let's step into the bathroom, so we can get you cleaned up," Ann states. (Cleaned up for what?)
I step inside the bathroom and Ann follows. She says, "We're going to clean out your insides. Bend over the toilet, please."
I bend over. She inserts a tube in my read. I feel fluid coming in and it's not stopping. "I think I can't take anymore," I exclaim.
"All right," Ann says. "I'll turn it off. Just keep in that position for five minutes." (I wonder why my rear needs to be cleaned.)
I comply. She commands, "Now stand up and sit on the toilet. I'll pull out the tube and you can release." I follow her orders. The fluid pours out of me.
"Now, you're clean. Let's get you to the research room," Ann states. I get up and trail her down the hall. She enters the door at the end. When I enter, there are three females dressed in white clothes with long white jackets. They look like doctors.
"John, these are the researchers. They do have titles, but we are rather informal at SRI. So, John, please meet Alice, Luna, and Chloe."
"Nice to meet you," I say.
"We're glad you volunteered, John," black-haired Alice replies.
"We really are," brunette Luna continues.
"Definitely," Chloe, a blonde, concludes.
"Please have a seat, John," Alice says.
I sit down. The gown pulls up and my skin is touching the chair. My balls are barely covered. (It is both a little embarrassing and exciting.)
"Ann, has John signed his consent form and been cleaned up?" Alice asks.
"Yes, he has," Ann replies.
Alice states. "We are going to investigate how you react to stimuli of various kinds. We each have different types of stimulation and areas of interest. Our goal is to determine at what level of stimulus you achieve the maximum pleasure. There is a blurry line between pleasure and pain. So, you may experience a little pain while we adjust levels to find the optimum point."
"John, did you follow the protocol we sent? Have you had an ejaculation in the last seventy-two hours?" Luna asks.
"I have not climaxed for three days," I reply. (I feel a sensation in my cock.)
"Great. Then I guess we're ready. Ann, can you help John up onto the examination table," Luna requests.
I am led over to a table that has stirrups on one end. Ann helps me to lay down on the table and place my legs in the stirrups. Luna puts a cuff around my right wrist and connects it to a ring on the side of the table. Chloe does the same to my left wrist. Alice connects a cuff to my right ankle and clips it to one stirrup. Ann repeats on my other ankle.
The stirrups are adjusted so that my legs are spread wide. The gown I am wearing slips up so that my cock and balls are exposed.
"Alice, it looks like our attempt at modesty during the examination isn't working," Chloe says.
"You're right, Chloe. Our protocol suggests that the subject be covered in areas where we are not stimulating. Since we'll be addressing most of his body, I guess the gown isn't needed. You can just cut it off," Alice replies.
Chloe starts ripping the paper gown. It tears easily and I am now totally naked and restrained. (I feel very vulnerable.)
Luna wraps a strap around my stomach and the table. She tightens it so that I can hardly move. "This is so you won't move around and interfere with the measurements, " Luna explains.
"Luna, would you attach the monitoring sensors to the subject?" asks. Luna wraps a measuring device around my wrist, above the cuff. She also connects a device to my balls and cock. "Male, this will give us an objective measure of your response. One device measures your blood pressure and heart rate. The other measures your erection hardness. We'll also be asking for your subjective responses. I think we should start with nipple sensitivity. What do you two think?" Alice asks.
"That's sounds good," Chloe answers.
"Fine by me," Luna says. "I think we should start with pressure sensitivity with the calibrated pressure applicator." She goes over and returns to the table with a device that looks like a clip with multiple settings. "I'll start with the initial value", she says as she places the clip around my right nipple.
I can sense something on my nipple, but it doesn't feel like much.
Alice says, "Let's start recording the calibration. Luna, you capture the cock and ball measurements. Chloe, you write down the arm measurements. I'll note Male's verbal responses and adjust the pressure applicator."
I see Luna and Chloe write down something. Alice says to me, "Male, we need to get a response from you. The scale is one to ten. One means that you can feel something, and it gives a little pleasure. Five means that the stimulation gives you maximum pleasure. Six means the pleasure is turning into pain. Ten means that all you feel is pain and no pleasure. Do you understand the scale?"
"Yes, I do." I reply.
"Now we want to find the exact five spot for each of the stimulations. But first we need to calibrate our measurements. So, I will be increasing the pressure slowly. We'll measure your response, particularly the hardness of your cock. We went to check your subjective measure against these measurements. You say when it starts to feel a one, then two, and so forth."
"I think it's a one now", I state.
"Good, now I'll increase the level. Tell me when it reaches two,"
"That's a two."
"That's a three" (I can't believe that pinching my nipples is turning me on.)
"Four"
"Five"
"Six", I start to groan. Luna asks Alice to pause for a moment. She needs to catch up writing down the measurements whenever I say a new number. Luna says, "His erection appears to be decreasing. I think we need to back off just a little."
Alice replies, "Certainly. I'll back it off a little bit. Does this help?"
"Yes, the hardness is returning," Luna states.
"Good, then let's hold it here for five minutes to see if there is any change in reaction," Alice states. "What does this feel like, John?"
"It feels wonderful, but frustrating. I want to have a climax, but there is no stimulation down there," I reply.
"Well, John, if we gave you a release, then all our measurements would be off and we'd have to start over," Alice replies. "You'll get a release at the appropriate time."
"Thanks," I say grudgingly. (How long will it be?)
"John, if you want, we could take this to ten. You'd feel so much pain, you wouldn't even think about having an orgasm," she says.
"No, please. I will accept my frustration instead of pain," I reply.
"That finishes the calibration," Alice announces. "Let's give John a little break so he can become flaccid before we start the next part."
They leave me restrained and unable to move. My cock starts to fall without the nipple stimulation. Fifteen minutes later they return.
Alice, Luna, Chloe, and Ann return.
"Ann, would you put the measurement device in John's mouth," Alice requests.
"John, please open your mouth," Ann requests. I open it and Ann inserts a ball gag. She connects the strap behind my head.
"Now, John, we're going to measure your pleasure by how hard you bit down on the gag. A little pleasure is a light bite. A medium bite is maximum pleasure. Anything harder bite if you feel pain. Do you understand?", Alice asks.
"Mmm," is all I can say. I nod my head.
"Great. There is one more thing. If you feel that you must speak, bite down really hard on the gag. That will cause a bell to sound. Why don't you try that now.," Alice states.
I bite down really hard. A bell sounds.
"Good, it works," Alice comments. "Just a few more things to do. Ann, will you get the curtain. Luna and Chloe, please set up the cameras." (I'm going to be photographed?)
Ann places a curtain at my neck level. Alice steps close to my head.
She says, "John, we have the curtain for two reasons. One is that we want to measure the response you have from mechanical stimulation, not visual stimulation. The other is that we are going to video your responses and we want to keep you anonymous. That's what we had on the consent form."
"MMM" is all I can say as I nod in agreement. Alice steps back on the other side. (It feels a bit more exciting, not being able to see how and when they are going to stimulate me.)
Alice starts, "So let's begin. Here's the level of pressure that you responded with a one."
(I feel a little pinching. I bite down a little.)
"Very good, I see one on the monitor from your gag. We'll proceed as before," Alice continues. Alice increases the pressure. She counts off as the numbers on the gag monitor go up. "Two. Three. Four. Five. "What's the erection look like, Luna?", she asks.
"Same high erection as before. I'd go up one more to see if it decreases," Luna suggests.
(I feel my hardness. Would they please give me a release?)
"OK, I'll increase the pressure. John is responding with a six on the gag," Alice notes.
"Erection going down," Luna notes.
"Well, it looks like the gag works correctly. I'll back off a little and leave it there for another five minutes." Alice responds.
(No, not again.)
After the five minutes, Alice says, "Alright, that's the end of the stimulus." (I feel the pressure decreasing on my nipples.)
