'Honban wa Korekara desu yo?' Massage-shi no Ero Tech Shijutsu de Yogari Makuri!

I can only think about things that make me feel good... Yui, an office lady who has no boyfriend and is always working, comes to a popular beauty salon. However, the staff there is rude, the outfit she is given is almost entirely underwear, and to top it all off, the person treating her is a man...!? Yui tries to leave, but she is put off by the attitude of the staff and ends up receiving the treatment... It's a strange treatment, which makes her tingle wherever she's touched, including her nipples, and it escalates more and more. He even touches her down there. Her mind and body become completely melty, and it makes her cum...!?
