The Boy Who Has a Girlfriend

This senior boy I have always had a crush on made a move on me at a party once.

Only problem was that he had a girlfriend who I was somewhat friends with.

We ended up hooking up that night. People noticed we were both gone and came upstairs looking for us.

When they knocked on the door and we told everyone we were just talking and...somehow they believed it!

Since then we have been hooking up on and off whenever we both have free time.

I know it's wrong, but how can something so wrong feel so right?
