She gives you a lap dance. A vanilla one.

"You're a very naughty teacher," she giggles as you turn the music up and recline your seat.

"And you're a bad little girl," you chuckle. "But you owe me a reward. I suggest you get started."

Biting her lip she straddles your thighs as she climbs onto the seat, her body moving to the music. She unties her hair, letting it fall loose around her face, and puts her hands on your shoulders, swaying and writhing gently to the beat. She leans against you for a moment, pressing herself against you before pulling back with a sultry smile, then leaning forward again to let her hair tent over your face. You can smell the aroma of her perfume and her sweat and your cock starts to stiffen at the sensations of having her so close.

She writhes and rocks through the song, squirming against you with a teasing smile on her face, letting her breasts rub against your chest for a moment then pull away with a giggle. When the song ends she leans her forehead against yours, letting her hair be a curtain around your for a moment before sitting back with a smile.

"There! My knight in shining armour has his reward!" she laughs happily. "Thanks again Mr. Sharp."

"Oh Lyndsey, you haven't even started," you chuckle, putting your hands on her hips. "I said a lap dance. And that means showing off these fine teen tits of yours. Come on girl, the next song is starting."
