Akutoku Yakuzaishi no Chiken Monitoring (V1.5) (RJ01114691)

This game is a simulation where you, the player, create various drugs and administer them to women who come in as clinical trial part-timers, then observe the effects.
You can, for example, create sleeping pills to make them drowsy or aphrodisiacs to arouse them.
And of course, while they’re asleep or under the influence… all sorts of things can happen…
