A game of bondage and machine sex. Hopefully the first of many translations of games by this circle. This translation requires the official game files to load images from, which can be purchased and downloaded from DLSite.
Characters: Hotaru and Ayu
Twin sisters with a sexual dependency are studied on bizarre, futuristic devices.
Constant orgasms in the "climax ward"! Humiliation and bliss!
Waves of pleasure send the girls into the sexual gutter in the name of a cure.

There is a sequel that has most/all of this game's features and an official English translation, that is probably a better option than this translation.
