I have a certain fantasy. It's a scenario where sex or nudity is not normal, in public. A person is consensually but secretly stimulated to orgasm while they try not to let anyone know they're being stimulated. The "victim" may or may not know who is doing it, and there may be more than one person doing the stimulating.
For example, an office conference room, a woman sits down for a meeting. Unknown hands show up and begin touching her. As she lets them continue, she participates in the meeting. The hands get bolder and bolder, and soon have exposed her under the table. She gets fingered/licked/toyed until she has an orgasm, all while trying to maintain normal composure to other meeting-goers.
Another example: A guy is sitting in the living room talking on the phone, and his girlfriend/wife gives him a blowjob while he tries to prevent the other party from figuring it out. If the other party figures out that there's sexual activity then all sexual activity must stop. If the other party hears a noise the "doer" makes then the doer loses. If the "do-ee" has an orgasm silently, that do-ee wins. If they have an orgasm and are found out, then the doer wins. I've actually played this game with girlfriends in the past, and it can be extremely fun. It's also relatively safe in that you won't be arrested for it if you are found out.
Another example: Two people on a commuter train, one is seated and the other standing. The sitting person fondles the standing person while the standing person holds a purse/coat/whatever to hide what the sitting person is doing.
It doesn't matter to me if the event is discovered or not, both are pretty hot to me. It doesn't matter if the other people involved stand and watch, or take part somehow, as long as there is consent. If they are discovered I think embarrassment is much better than not.
I know that there is a name for non-consensual train gropes, chikan. I don't like non-consent. I like spontaneous and surprised, I like the idea of strangers "bumping" into each other, I like anonymity. But with consent.
While I realize these scenarios are highly unlikely in real life, I would think there is some sort of word that describes it. The few porn videos I've found with this sort of thing are extremely hot.
Thanks.
