By doing her against the window.

Mr. Barstow wraps his arms around Liza and kisses her hard. You feel everything he does, so you enjoy the kiss. You also enjoy the sensations his hand feels when he moves it to her big tits.

"Lizaaaa," moans the teacher. "You feel so... unh!" his other hand slips under her tiny cheerleader skirt and caresses her ass. "I wish we didn't have to hide this."

It's a reasonable request, so you wish it was true. Now a teacher sleeping with an 18 year old student is completely acceptable.

"Come over here!" Mr. Barstow leads the young hottie to the window. He turns her towards it, so her naked rack is facing out and her ass faces back towards him. "I want to do you right here."

"In front of the window? I'll get in trouble!" Despite her protest, she leans against the window sill and smiles.

"No you won't. Class is in session and there's barely anyone out there." He unzips his pants and pulls out his cock as they watch a maintenance worker mow the lawn. "Besides, what will you get in trouble for, exposing yourself? I doubt many people are gonna complain about this view."

The teacher reaches around and squeezes one of her wonderful tits. His arousal adds to yours, and Liza builds it even higher by moving her perfect ass up and down against his cock. Mr. Barstow pulls up her tiny green skirt, pushes aside her matching panties, and slides his cock delicately into her pussy.

Once he's completely in, Liza starts thrusting her hips back and forth, working his cock slowly. All you can see directly is her long, reddish brown hair on the back of her head, but a reflection in the window shows a sublime smile on the girl. Then you notice Mr. Barstow's face in the window. It's strange looking through someone else's eyes and seeing someone else's face reflected back. However, as different as the face is from yours, the intense desire in his eyes matches your own needs.

Mr. Barstow fucks Liza back, shoving hard into her tight pussy. He continues fondling her greedily as his desire builds. He gets to the point of cumming, but you wish for him to hold out. He continues pounding and groping the stacked cheerleader as she moans louder and louder. You wish for the classroom to have soundproof walls right before she screams through the biggest orgasm of her 18 year old life. You let Mr. Barstow cum too and they both sing out as their juices mix.

The couple disengage and start making plans for a date. Feeling generous, you wish for the teacher to always hold off cumming until his partner is ready, then you wish yourself back to your body.

"Very good," says Mrs. Wiggins, the arts and crafts teacher. "I had no idea you knew how to make Pilgrim corn dolls! Would you please show the class how you did it?"

Whoops. Looks like the autopilot you wished up for your body was a little too competent.
