I imagine these will always take place within the context of you submitting to a partner, and I’m curious about the most humiliating orgasms that you fantasise about.
Maybe it’s a group all taking turns until your orgasm is an absolutely inevitability?
Maybe you’re instructed to grind on your partner’s legs until you cum like a bitch in heat?
Maybe you have to squat on a suction cup dildo in front of your partner and ride it until you cum?
Maybe there’s a wand vibe attached to the corner of a dining table and you have to drop your knickers, thrust your hips forward, and hold yourself against it until you have a messy orgasm as the dinner table?
Maybe it’s something else entirely?

I’ve wanted to try being tied up and left with a wand on me until I’ve had X orgasms. I’d absolutely hate it!
Maybe that wand isn’t even touching your most sensitive parts, so eventually you cum, in front of your audience, but it is a dull unsatisfying orgasm that makes a mess but only serves to leave you even hornuer than you started?
Ooo being watched or at least in view of other people would make it so much worse.
