[ADN-715 English Subbed] – 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

ADN-715 English Sub. I have a strong sexual drive and habitually masturbate twice a day. Because of this, sex with my wife who is trying to conceive results in low sperm count, making pregnancy difficult. Frustrated, she tells me to abstain for three days, and I reluctantly agree. During a heavy rain, my stepsister Hikari, soaked and with her chest wet, visits while my wife is away. Unable to control my built-up desire, I end up acting on impulse with my stepsister.
