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?

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.
