Agree to fuck her. Duh.

At first, you're a little taken aback by Kara's bluntness in broaching the subject but, now that you're at this point, there's no fucking way you'd pass up this opportunity. Not only is the girl you've been trying to screw all night flat out asking for it, but she's asking for revenge sex! You've been hate-fucked by a few girls in the past and know from experience that it makes a girl very open to suggestion.

"I don't see why not," you reply as nonchalantly as possible, your dick already stirring at Kara's lewd suggestion.

"So, what should we do first?" Kara asks, all wide-eyed and innocent with her cheeks flushed red with embarrassment.
