In the School Restroom

Schoolgirls Park Ah-yeong and Pinda smoke in a school restroom and use male student Kim Sang-woo as a seat while bullying him. Ah-yeong drops his glasses into a toilet and is about to urinate on them when a female teacher barges in and catches them smoking. After the teacher leaves, Sang-woo lifts Ah-yeong's skirt, gropes her buttocks and breasts, and has vaginal sex with her in a stall while recording it on a phone; Pinda knocks outside urging them because the teacher has gone, yet they continue. After he cums inside and semen drips from her vagina, he offers to delete only the first recording and she angrily demands every video be deleted. Ah-yeong later seeks another male student for more sex.
