I had a vague idea, but it seems that my junior colleague Kashiwagi-chan has a crush on me. After a drinking party, I missed the last train and Kashiwagi-chan invited me to stay at her room. However, the room I arrived at was a very small one-room apartment, and there was no place to change clothes, so there were many incidents of her breasts and panties showing! Kashiwagi-chan with wet hair was strangely sexy, and because it was small, our bodies were pressed against each other, and I was on the verge of losing my mind! To make matters worse, her braless breasts were pressed tightly against me, and I couldn't take it! No, cheating on my wife is bad, but Kashiwagi-chan's sexual pranks were escalating more and more...!!
