Regan never claimed to be punk. She says on her myspace that she's into a lot of different music. Hardcore and punk are some of it, but not all.
Anyway, I like Regan. Riley is hot too, but Regan has this combination of girl next door and total slut that really shows up in her scenes. She kinda comes off as innocence being defiled which is super hot and transcends appearance. That, and her blowjobs are fucking awesome. The way she drools and moans while deepthroating a dick is too intense.
