Reviews
I used it when I went to Nagoya on a business trip, because it was a straight staff, so the eroticism was subtle, but it was so erotic that I thought that it was treated unilaterally by a straight-looking little handsome guy. It was a room in an apartment, but it was a beautiful room. Recommended for those who like it tightly.
The straight staff was too nice. Massage technique seems to be improving, but I am very satisfied with the eroticism. If you go without showering because it is straight, it will suddenly stimulate the G spot, so you need to prepare so that you will not be embarrassed.
