[PRED-750] While accompanying my sister-in-law on a business trip, a sudden downpour left us in the same room... I couldn't stop cumming at her wet, see-through figure until the morning came... Shiramine Miu (Censored)

Taking refuge from the torrential rain, we share a hotel room. My sister-in-law is unaware that she is wet and see-through [10 creampies in an adulterous affair] My brother's important person. I absolutely must not touch her... but I'm alone with the sexy Miu in this closed room, and there's no need to worry about being found out. The more I think about it, the more my reason fades away... I don't care what happens! I attack Miu while still soaking wet. There was no way I could hold back. After that, I kept getting erect and devoured her and creampied her until the sun rose.
