OYC-312 - My best friend passed out, and his girlfriend is begging me to fuck her right next to him

I tagged along on a trip with my best friend's couple. While drinking, the girlfriend said her boyfriend was cheating on her, so she wanted to cheat back as revenge and begged for sex, leading to an unexpected revenge hookup!! However... the content was good, but if you're going to do a revenge hookup, you should've gone all the way to an internal ejaculation at the end! I was a bit disappointed!! Please make this a series or change the situation a bit and include internal ejaculation next time! Cast: Mio Fukada / Moa Hoshizora / Miina Wakatsuki / Yukiho Shirase
