Kaho Hanamori plays an adult student who finds class unbearably boring and would much rather fuck her adult upperclassman. She claims a gal's nails were made for teasing nipples, first rubbing them through his uniform shirt and then working both nipples and his cock in the hallway. Even gym class cannot stop her: she traces his areolas through sportswear, blows on them, flicks them with her tongue, and slowly covers them in saliva. Once they start fucking, she keeps playing with his nipples in every position while his cock twitches deep inside her. Her relentless teasing leaves submissive men thrilled—and may explain why the upperclassmen's grades keep dropping.
