A word a month – Chōkyō
From the dictionary of unusual sex:
Chōkyō – A Japan-only genre of computer games. The word means ‘animal training’ and the inspiration comes from the old Tamagotchi (do you remember it? In ’96 it became a global mania, with virtual pets to be lovingly raised). The difference is that in this case the “pets” are >biyōjo held in captivity to be turned into perfect sex >slaves. Clicking the right icons combination a series of parameters like ‘>libido’, ‘>depravation’ or ‘>masochism’ get modified until new activities and behaviors are unlocked: to win the game you have to permanently destroy all resistance in the girl.
