Escaping the torrential rain, I ended up in a hotel room with my sister-in-law. My brother's precious person. Absolutely must not lay a hand on her... but in this sealed room, filled with lust, just me and Miu-san, no worry of getting caught, the more I think about it, the more my reason fades... Screw it! I'm soaked through, and I end up assaulting Miu-san. There was no way I could hold back. After that, over and over again, until dawn breaks, I keep ejaculating inside her.
