I discovered a dangerous indulgence of the owner of a certain high-end inn... a forbidden hidden camera tape of guest rooms!! 'The Ultimate Bastard Hot Spring: Private Bath No. 16' in a remote hot spring facility... where private baths are available, and it's said that numerous couples in various relationships make use of them... we have carefully selected such 'problematic' couples for you!! Each with their perilous relationships and dangerous plays!! Which couples will be staying this time... please enjoy observing at your leisure!!
