Airi, a schoolgirl obsessed with "papa-katsu" and completely neglecting her studies, is given a drink laced with aphrodisiac drugs, turning her entire body into one sensitive erogenous zone. While in this state, she is tormented with sex toys, inducing massive squirting orgasms. Finally, her dumb, tight, and hypersensitive pussy receives a deep, serious creampie. The pleasure she experiences is beyond imagination.
