When I was in college I was hurting for money, as many students do. A friend of mine told me about how there’s some medical labs that will pay people to participate in their studies. Some even require overnight or weekend stays. There was a sexual research lab on campus that had done some important studies and was nationally known. I noticed one day on the bulletin board they were seeking subjects for a sex study of some kind and to inquire at the lab. I was curious since they hadn’t any more details on the paper on the bulletin board.
The pay was great for several hours. I asked what was required of me and if I qualified. There were some glances made between the lab workers and then they told me there were some new studies about women and sex toys they were working on. I had to fill out detailed questionnaires about my masturbation habits and sex toy usage, if any. I didn’t mind too much. Then there was a private room, but I was told it would be filmed for research purposes. There was an odd looking and large contraption that was some kind of a fucking machine with artificial tongues on another part of it.
I was told to lower myself down onto the lubed up fucking machine dildo and turn on the tongues to whatever speed felt the best for me. I was a bit hesitant with a lab assistant in there, but focused on the money I’d get afterwards. I lowered myself down onto the toy and turned on the tongues and it honestly felt great, even though it looked really weird. I’d had a threesome the year before and it reminded me very much of when I’d gotten fucked by one guy and had the other one licking me at the same time. I came pretty well with this odd device and they let me rest for a while and then had me do it again. After about five orgasms, I was pretty exhausted. They thanked me, paid me and then I left. Pretty easy money, but a bit of an odd study. I didn’t tell my friends what all was involved in this one!
