Why do I fall for the bad boys?

Corinna

Davids POV
"Hey babe you wanna come over later? We can have some fun" Corinna said. "Corinna idk where you came from but I gotta get to lunch. See you later" "what so you can jsut go to that bitch Liza? She's not even as pretty as me and you know it. In willing to do anything to be with you. Anything. Please let me be w you?" She begged. I wasn't having it. I pushed her off of my arm and went to lunch.
*after school*

"David there you are! I've been looking for you, can you give me a ride home? I love a while away and my brother isn't going to pick me up today because he's got to hang w his girlfriend." She said. "I mean I guess. Get in" I say annoyed. I wanted to be nice tho because she is a nice girl she's just annoying. Liza is hanging w Gabbie today so, she wouldn't mind right? When I get to Corinna's house I walk her to her door because it's just a nice thing to do. Then she pulls me in for a kiss and I didn't want it. At first. Then I started to ease into it and soon I melted into the kiss. I kept telling myself this is wrong, because it was, but I couldn't get enough. It was like my old lifestyle. All the girls would throw themselves at me and I haven't had that in a while. I am happy with Liza though. As I was making out with Corinna I opened her door and closed it and pinned her against it. I couldn't stop. It was like a drug to me. Old habits are coming back. Stop David stop. STOP. I get off Corinna and she gets annoyed. "What David I thought you wanted this" she said. "I don't. I don't want this at all. I have a girlfriend and I love her. I really love her. I can't do this to her." I said. "You already have." And she pushed me out of her house. I get in my car and sit there for a while contemplating telling Liza or not. I don't know if I will. I should but I won't. She doesn't need to know. Little white lie. Right?
