"My bathtub is broken... Can I borrow it since we live nearby?" It's a story that seems impossible to believe: My colleague, Ito-san, the envy of all the male coworkers, is taking a shower in my room right now. I have a girlfriend, so I don't want to get involved in anything troublesome, but I also want to admire that glamorous body... Struggling, I couldn't resist my ulterior motives and ended up peeking into the shower. I tried to act calm, but she said, "You were peeking just now, weren't you? Are you excited?" She knew everything... and even found out I was a virgin, which was embarrassing! Or so I thought, "Well, maybe I'll be the first one to take her." Huh? I'm so shy I've never even had sex with a girlfriend, so I suddenly lost my virginity! Ito-san's body and technique are so amazing, it's irresponsible and I ended up cumming inside her without permission! No matter how many times we did it, my erection wouldn't stop, and I was so engrossed in it that I fucked her like crazy all night.
