The light was what actually woke me up, I squinted my eyes trying to shut it out to no avail. I put my hand over hand over my face and that didn't help. I felt like shit so I pulled the pillow over my head and went back to sleep, not thinking about what happened to me or what I was in the middle of. I woke up again later, to a beeping noise and it started to come back to me slowly. I was in the lab where I had been a paid part of an experiment. The last thing I recall was hearing a tech call out, "It's actually working!"
I removed the pillow and found myself in a very dimly lit room. The only illumination was the glow of the monitors around me. I felt them sheet over my body and could tell I was naked under it, just as I started the procedure. I just lay back and enjoyed the rest, except for the beeping. Recalling the events of the morning, getting to the lab, the young female technician that prepped me for the procedure and the tender touch she had as she shaved my pubic hair. Her touch was amazing and to my embarrassment my cock grew in her hand as she shaved my balls. When she finished she gave my cock a slight squeeze and said, "Maybe I'll be back later" She was not much older than my daughter and favored her a little too. My cock pulsed in her hand with the hope she would be back.
As I lay there thinking about her she entered the room saying, "I told you I'd be back."
My cock hardened at the sound of her voice, "So glad you made it back, I Was just thinking about you."
She said, "I can tell, have you seen yourself lately?" I looked down and my cock was tenting the sheet. Her hand went below the sheet grabbing my stiff member, I lay my head back as the sheet fell off my body. "Oh my... Nice.." was all she said as her mouth enveloped my cock.
Her skills were amazing, the suction strong, and the way she twirled her tongue around my shaft was to die for. As I was getting close I looked down at her. The only thing that I saw was her mouth stretched open and her hands grasping air. I could feel her and cupping my balls her mouth on the head of my cock but they were not there. It was too much to watch and as I came filling her mouth with my semen. She pulled off of my cock and two more squirts erupted out of nowhere followed by a trickle that produced a cum covered partial outline of my cock. Being a good girl the nurse took me into her mouth and cleaned me up.
I said, "Thank you, that was amazing, looks like the procedure worked."
Running her hands over my chest, or where it should have been at lease she smiled and said, "Yes it did, and I've wanted to do that for the last week."
I could feel my hard-on returning and when arm brushed mine she felt it too. I asked, "A week?"
She said, "Yeah you woke up once and wend back into an I guess the best description is a shock-induced coma. The blow job was one of the doctor's ideas when they saw me on video shaving you. The thought it might distract you a little bit. I have another idea if it's okay with you."
I had an idea what she meant but I let her suggest it, "What do you have in mind?"
With that she removed her shoes one at a time while smiling at me, "Oh I think you know!" her face touched my chest when she bent at the waist to remove her panties. "This is going to have to do, as I don't want to get busted in her naked." She lifted her skirt revealing creamy thighs with a bright red patch of red hair growing between them. The hair was turning darker as her own juices flowed out of her.
As if in a trance I watched as she felt around my invisible body, she climbed up onto the bed and I watched as her pussy split as the head of my cock was rubbing her clit and then the lips of her pussy opened, and I sunk into the beautiful batch of read hair. The lights were dim but it was wild to watch her ride a non-existent partner. My hands worked up her body, unbuttoning her uniform top allowing her braless breasts out into the cool lab air. I watched where my fingers squeezed her breasts and teased the nipples. Even though I just came I could feel another orgasm coming on. I was trying to hold out until she would cum. I felt I was losing as my first squirt came out and she spasmed, her pussy clenching at the nothing inside of her that was my cock. When she got off of me I was coated with our combined juices from about my navel to my upper thighs.
I said, "Thank you, that was .. just was ... wow."
She grinned, and replied, "I agree Wow is the only way I can describe it too. But we need to get you a shower."
She helped me up and walked me to the shower, set the water and helped me into the stall. The steamy water of the shower outlined my body as I soaped up. My erection had returned partially, but it faded back down as she tried me off and got me a robe. Looking in the mirror at just the robe made me realize what was going on, I mean really what was going on. I was invisible.
The Doctors came in not long after the nurse left and was talking to me. Telling me how the effects should wear off in a day or two. Explaining that bright lights hurt my eyes because I now have no pigments to block them, or eyelids. That I would need a mask to sleep in if the room was not totally dark.
The days came and went, I got a couple more visits from the love red-headed nurse and we had some fun. Then she got the holiday weekend off and by Tuesday morning I was visible again. Some tests were run. As the doctor proclaimed, I was good as gold and unaffected by any residual side effects. I was sent on my way the next day. The nurse and I, her name was Julie, never saw one another again.
Long story short, Home was an apartment building I own, I occupy a two-bedroom apartment with one of them converted to an office. It was close to the home I bought for my Ex-Wife and our two 18-year-old daughters lived after the divorce. Actually very close, about a block away, but as often as I saw my daughters you would think I lived on Mars. This whole "procedure" paid enough to pay off the remainder of the debts I had, not a huge debt but it helps to not have to work to pay for the building, and the other apartments have enough rental income that I come out ahead.
So back to the normal boring life I lead, day in and day out, fix this problem, plunge this toilet, etc. One of the tenets had a 19 yo son whose room was directly above my office, every Saturday night his mother would go out and he would have his girlfriend of the day over, and I would get treated to the muffled moans of the barely legal young girls.
The second Saturday since I got out of the lab, I got a phone call from the doctors asking if all was good with me. Seems one of the other volunteers had a relapse and since I was the first, if I hadn't by now I would not.
