YUJ-036 Because of my wife's sister taking the thick semen I had saved up for trying to conceive, my wife can't seem to get pregnant… Fiveba.

Film Introduction

My wife won't have sex with me unless it's for trying to conceive.
On the other hand, I can't go a day without ejaculating due to my strong sex drive.
Even my gynecologist scolded me that if I don't abstain a bit, my sperm count will be low.
I tried to abstain but...
Every weekend, my wife's sister comes to our house and extracts the accumulated sperm from me.
