The personal trainer Nanami-san who started accompanying me at the gym I began going to was very charming in her tight training wear, and I would secretly look at her with lustful eyes and get excited. One day, during a training session where our bodies were pressed tightly together, she noticed my erection. As I tried to cover it with my hand, Nanami-san forcefully grabbed me from behind and glared at me. 'What are you thinking? Do you have any motivation?' She scolded me like that, but then she started tracing her finger over my swollen crotch...！！
