DSOD-037 - Trapped in a Yakuza den, watching my girlfriend succumb to drug-fueled orgies for a week

My peaceful life was shattered when Yakuza thugs kidnapped me and my girlfriend, claiming she was their property. They locked us up and forced me to watch as she was subjected to a week of drug-induced sexual training. If she survives their depraved orgies, they might let us go. Can our bond survive this nightmare?
