Amanda Seyfried, especially like in Mean Girls where her hair sometimes looks red, yum, and if she wasn't so dumb (I imagine she's v clever in real life).
In my fantasy she's a sexy lil stepsister, but also bookish and shy - if she wanted me I'd be powerless to resist. One day I'd we walking around the house aching to cum because I hadn't had anything for months, and cos she's psychic she'd know. And she'd ask me if she could give me a blowjob, and go to work on me with those lips and sweet warm mouth and ooohhhhhhh... she'd be a gorgeous disgraceful mess by the time she'd finished draining my balls.
Yup, that'd do me.
(Yea, I have a thing for cumming all over pretty girls.)
