Tsubasa is 22 years old and attends a sweets vocational school. The first experience was three years ago, and the number of experienced people is about 6 people. Many of the other men had normal sex, but I couldn't forget the older man's S-like sex that I allowed when I got drunk. I was a little frustrated because I couldn't ask my current boyfriend to do the same thing. Furthermore, I started to be interested in the pleasure of anal sex in a book I read recently. I decided to look for someone on a dating site to see if there was someone I could have a relationship with just by having sex. One day, I got in touch with an uncle who was playing with a dating woman in a group and became interested.
