I Can Do Anal Though...

Blair's parents have left for the night, and her new boyfriend is dying for some action. He starts kissing her and things get hot, but as soon as things start getting too heated she pushes him away: she’s a virgin, and insists on keeping it that way. Xander keeps trying and eventually she lets him go down on her - but again, no sex. What the hell! Xander is about to give up when she brings up the idea of anal: that would allow her to keep her virginity, right?
