As the student council president, Mahiru solves all the students' problems. For those troubled with being uncircumcised, she skillfully teases with her tongue before deepthroating all the way to the base. When a teacher becomes aroused by the scent of her uniform, she willingly offers her body. Scenes include giving handjobs to perverted men on trains, giving her brother a blowjob at night while grinding her ass against him, and getting facialized by students. She gets scolded for skipping health class and moans cutely, a highlight of her submissive side. Another highlight is her enjoying full intercourse while licking the body of an extremely masochistic senior.
