A mismatched con cafe in a busy area of Tokyo. While the pink-haired girls with mentally unstable makeup smile blankly and say, "Welcome back?", "we" the regulars and the manager are plotting a secret deal. At the after-hours "celebration party," they incite the girls with drinks laced with imported high supplements. "Just a little trick and they'll get you horny in no time." At first, the atmosphere is light-hearted, but soon the breath changes to one of heavy breathing, someone's clothes are torn open, bodies are touching and gazes are melting. Before you know it, everyone is in the grip of pleasure and are engaged in group drug-induced sex.
