A flat out fantasy. What would it be like to be a test subject for a very specialized treatment?
I jack off daily, sometimes twice a day. I originally grew up in a very religious household where sex was not discussed. As a result I worried a lot about masturbating, but did it anyway. After I got away from the religious stuff, my fantasies took off in a guilt free environment. This might be why they're a little odd, from being repressed a lot!
Anyway: one of my predominant fantasies, and one that will make me cum just about every time, is about being hooked up to a masturbation machine that is controlled by a big busted, wide hipped woman wearing a nurse's uniform.
The fantasy always involves me volunteering for a medical test study. I go into the waiting room and I am admitted to the office, where a nurse explains to me that the study is on a new device that is designed to help with stress. She doesn't say too much more than that, but she does say, "I think you'll like it. It's a little like biofeedback, but more fun." I sign the consent papers.
She then leads me into a room with a big black chair, a bit like a dentist's chair but more comfortable, and she asks me to strip and lie in the chair. "Why do I have to strip?" I say. She replies "It's part of the medical exam for the test." I'm a bit embarrassed at having to strip down in front of the nurse but I figure it's for science. She puts my clothes in a locker and leaves. I find myself half hard, and I wonder what kind of physical exam it is and exactly what test I signed up for.
A little while later a second nurse comes in. Even through the uniform it's evident that she has a fantastic body, with great tits and wide hips, and very pretty. She is wheeling a machine ahead of her that has a number of tubes hanging off it. It's about the size of a small bookcase, lots of lights and lots of meters. I'm confused and a bit worried.
"Good morning," she says. "Did anyone explain what the test is about?"
"I was told it was stress relief, kind of like biofeedback," I reply.
"Well, it is. But it does involve a bit more than that. Do you have a problem with being restrained?"
Now I'm getting a little alarmed. But aroused. "Restrained? How come?"
"Nothing to be alarmed about," she replies. "It's just that the sensors are very sensitive and if you move around a lot inadvertently they might come off. It's really nothing to worry about, and if you don't want to do it, you can go now. We wouldn't want to do anything you don't want to do."
She sounds reassuring. "OK," I say, half hypnotized by the outline of her boobs and her big blue eyes. "Just lay back and let me take care of it then," she says.
She restrains my hands and feet with leather cuffs that are bound to the chair. I can't move. "Not too tight, is it?" she says. "No," I reply. I am conscious that my cock is starting to get hard again, and a little embarrassed.
She then wraps a band around my head that has wires trailing from it back to the machine. She also puts some sensors on my chest and stomach. "This is the biofeedback part," she says.
Then she pulls out a tube. I notice that the tube is just about the right size to fit a cock into. She looks me in the eyes and says, "I can see you're becoming aroused, and that's OK. What we're doing here is we're testing a male stimulation device that's designed to reduce stress in men who are under an exceptional degree of stress." Then she hooks a smaller tube to the bigger one. I notice that the larger tube has a rubber liner. She lubes up the bigger tube, and then reaches over and spreads lube over my cock. It immediately springs to attention.
"This is a nice sized penis," she says with a smile. "I think you'll find this fun. We're going to stimulate you and measure your response to how well the machine does."
She strokes me till I am almost completely erect, and then, without warning, she slides the tube over my cock, and flips a switch on the machine. The rubber liner clings to my cock. Then she flips another switch on the machine, and the tube begins moving up and down on my cock, very slowly, with a slight hiss of air.
"Is that OK?" she says. "It's not painful, is it?"
"Uh...NO," I manage to reply. "Good," she says.
She keeps the stimulation slow and then says, "We're going to increase the speed a little bit." She rolls a dial, and the speed of the sucking cylinder picks up. I notice she seems to be enjoying her work. She looks a little too lascivious. "Do you like that?"
I can barely reply but I manage to gasp, "Yes!"
For the next hour she increases and decreases the speed of the sucking, sometimes adding vibration, but each time I get close to cumming she slows down the pace until I can get my breath. I am sweating and shaky but I feel fantastic.
Finally she says, "I think it's time for you to cum, and since you've been a good subject, I would like to give you a reward." She drops the lab coat, lifts up the scrub top, and undoes her bra. Her big, round, pale, full, soft breasts fall out. She playfully tweaks her nipples. "There you go," she says. "Now, will you come for me?" she adds coaxingly.
"Yes," I say. "Let me cum for you."
"That's what I wanted to hear," she says. She twists a dial and the machine begins sucking on me faster and smoother, all tight and slippery at the same time. It only takes a minute or two before I start to boil over. I cum in the machine, jerking in the chair and pulling inadvertently at the restraints, as the machine powered by the nurse takes me over the top.
Gradually she slows the machine down. Then she puts her top and her lab coat on. She reaches over and releases the tube from my cock with a "pop," and then undoes the restraints. I lie there panting.
"You did very well," she said. "We got a lot of test data from that. I'd like you to come back next week for a further try out after we make some adjustments. Are you available for that?"
"I'll make time," I say.
She laughs. Then she looks at me and lowers her voice a little. "I want you to have this," she says, and puts her bra into my hands. "I want you to think about that this week, until you come back next week." Her voice becomes quieter and more intense. "I want you to think about my big, fat boobs." She locks eyes with me. "I think I know what you'll do with that."
"I think you're right," I say. "Good," she smiles. "Get dressed. The receptionist will set you up for next week, and the check will be in the mail. Thank you for participating in the study."
"Stud," she adds, almost under her breath.
She leaves the room and I start to get dressed. I wonder how long this research will take, and decide I don't care.
OK, that's my fantasy. A little off beat, I admit. Hope you enjoyed!
