A big-boobed hentai vixen finds herself the center of a diabolical game of nipple torture. Her husband, driven by a fetish for her inverted nipples, uses every tool at his disposal to tease and torment them. Clamps, pumps, and even his own mouth are employed to stretch and stimulate her sensitive nubs, driving her to the brink of orgasm and back, as she writhes in a pleasurable, yet twisted, dance of submission.
