[Chinese]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 sex drive, and jerking off twice a day is part of my daily routine. Because of this, during sex with my wife who's trying to conceive, I don't produce enough sperm, and we haven't been able to have a baby. My wife, having lost her patience, scolded me to 'abstain for three days,' and I endured it with tears. Then, in the pouring rain, my wet-through sister-in-law, Hikari, showed up. My wife was out, leaving me alone with my sister-in-law whose breasts were see-through from being soaked... I couldn't hold back the sexual desire I'd built up over three days and ended up attacking my stepsister.
