I was a science experiment

[Clearwater]

When I was in 11th grade I rode the school bus, the only other students who rode this bus from my age group were Julia & Sissy, so we sat together. Julia and Sissy were both super smart, both made straight A's and were headed toward careers in medicine. They got off the bus together at the stop before mine, they didn't live far away.

One afternoon they asked me if I would help them with a school project, they were pretty vague about it, but they wanted me to get off the bus with them and go to Sissy's house. They were both pretty and always nice to me, so I jumped at the chance to spend time with them. We got to Sissy's, she was a latchkey kid, her parents didn't get home for a couple of hours, we hung out for a while, just talking about school, but I was curious as to what project I could help these two geniuses with. They were a little hesitant to tell me, but Sissy finally told me that she had received a new microscope for her birthday. Then Julia said that they were very curious and wanted me to give them a semen sample to examine under the microscope so they could see the sperm swimming around.

This sounds hot now, but back then I has zero sexual experience other than jacking off and this idea made me nervous. They explained that I could go in private and put the sample into a cup. They were laying the feminine charm on thick, so I agreed. They produced a sample cup and brought me to a bathroom. They didn't really think this through, not only was I nervous, there was no lube or porn, I even had a difficult time keeping a boner knowing I had 2 girl waiting for me to ejaculate. After about 15 minutes I came out and explained how guys worked, some simulation was necessary. Julia asked what kind, I explained that maybe seeing their boobs and and touching me would help.

They both immediately peeled off their school blouses and bras, now I had an erection, I took off my pants and boxers, neither had seen a guys boner so they were very intrigued. Sissy was the first to touch me, I told her how to stroke it, boom I came like a geyser. The microscope thing was actually fun, I got to see my swimmer guys doing their thing. This apparently was a big turn on to both of them.

Between then and the end of the school year, the three of us did this several times and I got to see them completely nude many times. We almost got caught by Sissy's mother when she came home early one day, so that ended our adventures.

This is a really cool story.
Will you be making this into a full story, with some fictionalized content added?
If not, someone here might be interested in using this to be the basis of a fiction story, inspired by your true event.
If you like that idea you can post a comment asking for a writer, and somebody might want to work with it.
I have too many things going on at the moment. Someone else would have to be your GhostWriter.

There is a little more to the story, I ran out of time. Both of them liked to play with my penis, of course I didn't mind at all, one afternoon they got some of Sissy's makeup to decorate me. They used lipstick, mascara and some other stuff to make my cock look like a little man, this ended up getting me off, we were laughing hysterically over how the little man deflated after I came.

Neither of them confessed to masturbating, I thought it was only fair that I got to see them. This particular day Julia wasn't there for some reason, it was just Sissy and me, we played and teased her and discovered that touching her clitoris felt better than fingering her vagina. I played with it until she moved my hand away and took over, that was the first time I got to see a female orgasm.
