A family member aware of before is served to me! - Part.2

There is a rumor going around that a private apartment-style scrubbing esthetic salon exists in a certain part of Tokyo. The rumor is that if you choose the scrubbing course, you will be able to have sex with a live girl.... With high expectations and a little money in hand, I went to the esthetic salon and found myself in the middle of a scrubbing course! What a surprise, I ran into my sister or sister of all people! The ultimate choice for those who just want to get laid. Will they cross the line? This is a thorough SCOOP of the story!
