DVAJ-562 A personal trainer sister, Kawakami Nanae, slowly and thoroughly keeps violating me, a gym beginner with no strength.

Nanami, a personal trainer, accompanied me at the gym where I started going. She was very attractive in her tight-fitting training clothes, and I was excited to see her secretly with erotic eyes. One day, I find out that I have an erection during training where each other's bodies are in close contact. Nanami glares at me, who tries to hide it with her hand, by forcibly squeezing her wings. "What are you thinking about? Are you motivated?" !
