I really enjoy stories and art about a "victim" who's inflated with so much helium (or other lighter-than-air gas) that they start to float. Especially if the victim is (or gets taken!) outside where they could be at risk of floating away. I don't know why, but for some reason the dominance/submission in that kind of situation really fascinates me, where the victim's tormentor could let go at any moment...
Anyone else with similar fantasies?
It's not just the helplessness of being inflated and floating away, but the helplessness of growing faster as she rises higher, that I enjoy.
