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?

That one is always fun :3
Being tied up with a vibrator hopelessly squirming as well, or cumming just from teasing without even getting to anything after the foreplay.
One that has happened to me so far was when doing orgasm denial stuff with my fiance, cumming just from seeing a naughty picture without even touching, which was quite fun :3
