FNS-088: My sister, who I thought was a kid until recently, started teasing me with panty flashes, so while our parents were on a trip I had sex with her multiple times... 浜辺やよい

About this work

I returned to my parents' home after a long time. I used to be close with my sister Yayoi when we were little, but we grew apart around my rebellious phase. When we reunited after a long time, she had grown up in an oddly sensual way. Maybe she wasn't fully an adult yet, because her underwear kept showing... or was she purposely showing it? A single piece of cloth dug into her crotch and barely covered her big butt. There's no way I'd get aroused by my sister... Then our parents went on a trip. Even when it was just the two of us at the family home, the panty flashes didn't stop. My sexual desire toward my sister didn't stop either. Once I made a move, there was no turning back: sex after sex while our parents were away. My sister couldn't possibly be this cute... this horny... And yet, even thinking that, I kept going.
