HUNTB-741 我们的家庭不知不觉间又添新成员了！“很高兴认识你！从现在起，我就是你的妹妹了。”和刚成为家庭一员的嫂子做爱，感觉太棒了！从大学开始……

Living alone has been my dream since college. A woman I didn’t know suddenly came there! From what I hear, it seems like she’s going to be my older sister. It seems that she is a step-sister who was born when her parents remarried without permission. Furthermore, since their homes are close, they often visit and help each other out as they live alone. I was supposed to clean up the room, but my sister-in-law discovered my AV and watched it, and she got horny and went into heat! I unexpectedly decided to have sex with my sister-in-law, who was a stranger to me until yesterday, but now she is my family!
