This is a secret place and we get to see Rio Haruna here. It has walls made of steel and she is the only occupant. This is a place we have seen before when Ria Sakurai was there and sucking cock to get a reduced sentence. We are sure that Rio will also want to try to reduce her sentence and do some wild things in order to do that. The jailer comes in and serves her the meal for the day and sees that she is looking very hot and sexy and decides she has been in long enough to think about how boring it is and she will do something to get out.
