One way to look at it: If he's ashamed of what he's done and doesn't want the girlfriend to know, then he's obviously broken the rules of his relationship, no matter what you call it. If it was okay, he'd not care if she found out. So yeah, I'd tell him to tell the girl, stating that if he doesn't, you will. Treat others as you'd like to be treated, you know. I'm pretty sure the girl deserves to know of this stuff so she doesn't waste her time with him, and then (optimistically) he might learn a lesson, too.
I once held the hand of a girl and got quite touchy with her, tracing fingers over her face while sleeping next to her one night on a school trip. I told my girlfriend afterwards because I felt horrible. We stuck together for months beyond that. I think it's better that the girl finds out from him, because that's the only way he'll really have a good chance out of all of this.
