A buxom, aggressive gyaru takes center stage in this amateur male masochist nipple torture series. Amateur men with hypersensitive nipples, recruited online, are handpicked by the female performer and summoned for in-person encounters. The documentary-style film captures the intense nipple teasing in explicit detail. In this first installment, nail-obsessed Tachibana Nao stars, using her long, sharp nails to torment the nipples of two tense amateurs. She invades their homes, straddles them to deliver relentless stimulation, and even pins them down on bar counters to mercilessly play with their nipples—dominating them in various positions. Beyond mere nipple play, the video also features Tachibana Nao’s lewd sex scenes as a major highlight.
