The tragedy of a busty girl whose body is heated up by an aphrodisiac and whose male friend plays with her I-cup breasts as he pleases. As her head becomes hazy, the man's hands reach her chest and into her pants, roughly groping her private parts. Even though she is rational, her body reacts each time, and the man points out her wet pussy. When a raw cock is inserted into her pussy, which has never welcomed a cock other than her boyfriend's, she convulses and climaxes multiple times. Kokoro and body are taken over by a cock that is bigger and longer than her boyfriend's.
