A schoolgirl is forced to pee outdoors because she can't find a restroom. Witnessing her defenseless state, a man who can no longer hold back applies an aphrodisiac to his cock and instantly forces himself into her. Although she manages to escape after being raped, her body begins to change. The aphrodisiac left inside her vagina heightens her sensitivity, making her pussy ache. She begins masturbating with her fingers and objects, losing all reason and becoming completely absorbed in outdoor masturbation even in front of others!!
