HUNTB-741 I didn't realize my family had grown! "Nice to meet you! I'm going to be your sister from now on." Sex with my newly acquired stepsister was too good! Starting from university...

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. She seems to be my step-sister who was born when my 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 her room, but my girlfriend's sister-in-law discovered my AV and saw it, and she got horny and went into heat! I ended up having sex with my girlfriend's sister-in-law, who was a stranger to me until yesterday, but now she's part of my family!
