Hina has a complex about her overly sensitive nipples. At a training camp for the track and field club, she confesses this to the captain and crosses the line by asking, "Want to check...?" The perverted advisor, who had been watching, threatens her about her club romance and slowly and thoroughly trains her nipples. Nipple stimulation with toys, nipple orgasm incontinence training, nipple-fixed rotor blowjob, and reverse night-time sex with tingling nipples. Her pink Tsubomi are flicked, pinched, pulled, and played with until she climaxes with her hard, pointed nipples.
