A newly opened luxury rental bondage apartment in Tokyo has become the ultimate dream for masochistic women. This unique residence enforces a strict rule: romantic partners and BDSM partners must live separately, drawing endless applications from women eager to experience its special environment. The first to undergo the manager's interview is 20-year-old student Yuria Ishida. Blessed with voluptuous F-cup breasts and an exceptionally high masochistic sensitivity, she faces a rigorous evaluation. Her body is thoroughly examined—where and how she feels pleasure, the extent of her training, and the skill of her servitude—all put to the test. Will Yuria pass? The answer is revealed now.
