Although I had been abstinent and had been saving up sperm in order to try to conceive, I found myself alone with my sister-in-law, who was drenched in the heavy rain, and I couldn't control my horniness...

I have a strong sexual desire, and my daily routine is to masturbate twice a day. Perhaps because of this, he did not produce enough sperm during sex with his wife, who was trying to conceive, and was unable to conceive a child. When his wife, who was desperate, scolded him and told him to abstain for three days, he was crying and holding back, when his sister-in-law, Hikari, came in in the heavy rain, soaking wet. My wife is away, and I'm alone with my sister-in-law, whose breasts are wet and transparent. ...I couldn't hold back the sexual desire that had been building up for three days and attacked my sister-in-law.
