Holy shit, unreal situation! Can't say I would do it myself, but I say give her a chance. She might be down for a fwb situation, as I doubt all that many guys are approaching her (especially in shape ones, no homo).
I'd just ask her out and tell her up front that you aren't looking for anything serious, and see if she takes the bait. My guess is that she will, and that she is more than ready for some D.
Also, where the hell are the pics? I don't care if you have to fake like you're texting someone and snap a pic of her in the process. You know it's what we're all waiting for! LOL
