He gets a blowjob

Xander couldn't figure out what was wrong with Buffy.

"So, what? We have sex and I get to get out of here."

"If you want."

"You'll do whatever I want?"

"Anything you want, that doesn't go against what Caleb wants."

So if he could get out by having sex with Buffy... "Give me a blowjob." That couldn't result in her gettin pregnat or anything.

As he sat down on the couch Buffy unzipped his jeans with her teeth and fished his cock out with her tongue. She had him hard in seconds. Remembering what Caleb said about a willing woman and a man Buffy put her all into this blowjob and was rewarded. In seconds Xander was groaning and placed his hands in her hair as he began to fuck her face.
