"One day, I became a human mannequin." When I woke up after falling, I found that my soul had been swapped with that of a mannequin used for sex education training in nursing school, and I was unable to move my body freely! The despair was short-lived, and a chance to turn my life around arrived!? Without realizing that I had been reincarnated as a mannequin, I participated in a dream harem orgy with all my students! Since I couldn't move, I had no right to refuse any erotic acts! Is this reality? When I woke up, I found myself in the utopia that men dreamed of! An erotic paradise called training!
