He figures it out

I just think something, and it happens? Thought Xander as his teacher started to go down on him. He looked around and saw the class's reaction. The guys were aroused, the girls were embarrassed. The girls in this room are jealous of Miss Calendar, and the boys are jealous of me.

Xander noticed the change in his classmates. Even Willow seemed to be jealous.

Willow Rosenberg would love to suck my cock. Right now Buffy Summers is fantasizing about me fucking her doggie style.

Buffy Summers was in her cheerleader gym class when suddenly she started fantasizing about her friend Xander fucking her doggie style. She had just put her gym clothes on when the fantasy came out of nowhere and it made her horny and embarrassed.

Right now Cordelia Chase is fantasizing about me fucking her up the ass.

Cordelia was in math class checking herself in her compact mirror when suddenly she started to fantasize about Xander fucking her up the ass. She dropped her compact on her desk as the unexpected fantasy flooded her mind.

Eventually, Miss Calendar finished Xander off and started class like nothing unusual happened.

Miss Calendar will never get into trouble for sucking me off. Every night, she fantasizes about sucking my cock.

Xander zipped up.
