STARS-792 — I Went on a Double Hot-Spring Date with My Best Friend and Her Boyfriend, Hit It Off with Him, and Secretly Fucked Him Like Crazy... Keep It a Secret — Ema Chizuru

I went on a hot-spring trip with my best friend and our boyfriends, but I ended up having sex with her boyfriend. He is not usually my type at all, yet our bodies were amazingly compatible. I had been sexually frustrated for a long time, and I was jealous of how lovey-dovey my best friend and her boyfriend were. Even though I knew it was wrong, sneaking around behind them and having sex was so exciting that I could not stop. Hey, this is really our secret, okay?
