She Had Been Abstaining From Sex And Building Up Her Sperm Supply For Fertility, But When She Was Left Alone With Her Sister-in-law, Soaking Wet From A Heavy Rainstorm, She Couldn't Control Her Horniness... Hikari Azusa

I have a strong sex drive and my daily routine is to masturbate twice a day. Perhaps because of that, during sex with my wife who is trying to conceive, the amount of semen is insufficient, and we haven't been blessed with a child easily. When my impatient wife scolded me, "Abstain for three days," and I was reluctantly holding back, in the pouring rain, my soaking wet sister-in-law Hikari showed up. My wife was away, and I was alone with my sister-in-law whose breasts were transparently wet... ...I couldn't control my pent-up sexual desire over three days and assaulted my sister-in-law.
