I'm a little confident in my body, but I wanted to try training with someone, so I signed up with a personal trainer. My instructor is Mei, a female instructor. Mei-san gives me a lesson wearing a competitive swimsuit, but I can't concentrate and end up getting an erection... Mei-san, who was curious about my swollen lower body, sucked the cock in her small mouth... and I was made to ejaculate over and over again...
