ADN-715 I was saving up sperm for baby-making by abstaining, but after getting soaked in the heavy rain with my sister-in-law and being alone with her, I couldn't hold back my urges... Hikari Azusa.

I have a strong sexual desire and masturbate twice a day.Perhaps because of this, I had little sperm in sex with my wife, who was trying to get pregnant, and I was not blessed with children.My wife, who was numb, scolded me for saying, "I'll abstain for three days," and I was holding back, sobbing when my step-sister, Hikari, came to me, in the heavy rain.My wife is away, and she is alone with her step-sister, whose breasts are wet and see-through......I couldn't control my accumulated sexual desire for three days, so I attacked my step-sister.
