Wind seems to fit the riddle

Thinking you’ve read this somewhere before, you go to the bound and penetrated sweaty Latina over the wind mat. When you step up before her, the helpless woman’s eyes focus on you with a pleading to them. She whimpers as she continues to balance fucking herself too deep and **** breast pain. You will admit the rope around her breasts make what would normally be somewhat large breast seem utterly enormous. Her entire body is drenched in sweat, especially her hair, which at one point must have been long, black, and curly, now hangs down like a dirty wet towel over her back and face.

You notice the pole she is empaled on is not only vibrating deep inside of her, but has a foot pedal at the base. It seems stepping on the pedal would drive the dildo further up the bound woman’s helpless pussy, while stepping off would allow it to fall back. She is already standing on her toes to try to relieve the breast pain, and the fucking may increase it and push her over the edge. Or you could be mean and focus on those swollen breast, torturing them in hope she is a pain slut and could cum straight from that.
