Lol, that sounds crazy so let me explain. When I was like 15 (I’m 19 now) I discovered that if I tense and relax my pelvic muscles rhythmically for like 10 minutes or so I can give myself a little “mini-orgasm”. So now I kind of do it as a habit? Like if I’m bored in class or killing time or whatever. I probably do it 5 times a day, sometimes more though. I don’t think I’ve ever been “caught” but if you were watching close I you’d probably see my eyelids flutter and maybe I’d bite my lip.
Anyway, this story is from last year, in physics class. I’m totally tuned out and using my little “superpower” and riiiiight on the edge of cumming when my teacher calls on me (“Jasmine?”) and it kind of startles me into having the orgasm. So I’m like feeling it roll over me and I KNOW if I try to talk it’s gonna be gibberish so instead I let out the biggest yawn I can to try to wait it out. And it works lol, I totally get away with it. And then I stumble through an answer which was mostly right even!
