[Hinano] has a complex with too sensitive nipples. At the track and field club's training camp, he confesses to the captain and crosses the line, saying, "Let's check it out...?" The perverted adviser who was looking into it threatens the love affair in the club and trains her nipples carefully. Intensive nipple stimulation with toys, prickly incontinence training, nipple fixed rotor blowjob, nipple tingling and reverse night sex. Pink buds are flipped, picked, pulled and fingered and fallen with sharp nipples.
