I was staying at my aunt's house in Tokyo for a few days while I was looking for a job. I met my aunt for the first time in a while and she was a muscle instructor and had a great muscular body. I consulted my reliable aunt about my premature ejaculation problem and she told me about it. The training began. I was instructed on the speed and frequency of masturbation, the time until ejaculation, whether or not I was allowed to ejaculate, etc. My penis was trained and my erection power increased, and I couldn't control my sexual desire, so I had sex with my aunt and came inside her!
