HUNTB-112 "Fake Marriage for Love" My sister-in-law, who has been dating her boyfriend for several years and wants to marry into a wealthy family but fears rejection, asks me daily to impregnate her...

My sister-in-law seems to be about to get dumped by her boyfriend, but he's quite rich and she doesn't want to break up. Cornered, my sister-in-law proposed sex with me, her younger brother, and a fake pregnancy marriage plan... My beautiful sister-in-law just wants the fact of being pregnant and is using me. And even though I feel guilty, I ended up accepting her proposal. Since then, secret sex has continued for several days, but as we are extremely compatible, my sister-in-law gradually becomes attracted to me...!?
