Ms Slide is testing out some new nipple clamps on an unfortunate chap. The clamps have conical springs attached, making the naked sub's chest resemble Madonna's iconic '90s bra, and the more the springs are tightened, the more his nipples are stretched and squeezed into pointy little man-tits, to Ms Slide's amusement and delight. # humiliation, nipple, femdom, CFNM, feminisation, sadism.
