Người bạn tình dục của tôi trông có trái tim thuần khiết nhưng là một con đĩ

Riena, a second-year working adult, is usually serious about her work. She may look serious, but she is actually quite a dirty girl. When I met her for the first time in a while, I found that she was feeling a little stressed out from work, so I decided to relieve her stress by having Nakadashi sex with her! A "convenient woman" is the word for her.
