Rubber-banded breasts
BDSM idea by Magnuz Binder.
For each wide, strong rubber band I add around the base of each breast, they constricts a little more, forcing your breasts to swell out even more, darkening in color and becoming more and more sensitive. With ten bands around the base of each breast, I grab the sensitive orbs and starts kneading them, balancing between pain and pleasure, while the rubber bands themselves slowly turns into bands of fire, making the taut skin at the base of your breasts start to feel like it's burning.
