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...!?
