ADN-715 I'd been abstaining from sex and saving up my sperm in an attempt to conceive, but when I found myself alone with my sister-in-law, who was soaked in the heavy rain, I couldn't contain my arousal... Azusa Hikari

I have a strong sex drive, and masturbating twice a day is a daily habit. Perhaps because of this, I don't produce enough sperm when having sex with my wife, who is trying to conceive, and we haven't been blessed with a child for a while. My wife has grown impatient and scolds me, telling me to abstain from sex for three days, so I tearfully endure it, when my sister-in-law, Hikari, arrives in the pouring rain, soaking wet. My wife is out, and I'm left alone with my sister-in-law, her breasts soaking wet... Unable to suppress the sexual desire that had been building up for three days, I pounced on my sister-in-law.
