I'm Really Sorry, I Fucked My Best Friend's Girlfriend.

The grass is always greener on the other side. My friend's girlfriend looks incredibly cute and sexy. 'I'm so jealous—I wish I could try that.' Such fantasies, for better or worse, become reality. In an unusual situation where I, my friend, and his girlfriend hang out together, she makes the first move. 'He won't find out, so let's do it.' Even knowing it's wrong, faced with a beautiful woman, a man's desires cannot be stopped, and I ended up doing it with my friend's girlfriend... I'm really sorry.
