During a business trip with my sister-in-law, a sudden downpour forced us to share a room... I was shaken by her completely unaware, soaked appearance, and continued to ejaculate inside her multiple times until morning... Shiramine Miyu PRED-750

The place I escaped from in the torrential rain was a hotel room. My sister-in-law, completely unaware of my soaking wet state [10 ejaculations in an illicit sexual encounter], is an important figure to my brother. I absolutely cannot touch her… But in this secluded room, alone with the charming Miss Miyu, without worrying about being exposed, the more I thought about it, the more my rationality vanished… It doesn't matter what! I got soaking wet and assaulted Miss Miyu. It was impossible to resist. Then, I repeated this many times, until I was exhausted and erect again, until the sun rose, greedily ejaculating inside her repeatedly.
