She starts to show you what she can do

"Why don't you show me what you can do Mikayla," you say with a smile, reclining your seat a few degrees. She smiles back and squeezes your growing bulge, then unzips your pants and frees your cock, stroking it with her slender hand.

"Mmmmm, you're very big sir," she says softly as her hand pumps your shaft.

"Do you think you can handle it?" you ask with a smile.

"I'll try sir, I'll do my very best." She spits in her hand to lube it and starts to pump your cock with a steady rhythm, giving you a sultry smile as she works.

"Did you do much of this last year Mikayla?"

"Yes sir. Several times."

"Were you the only girl who did?"

"Oh no sir. Several girls did. We had a bit of a competition to see who raised the most money."

"How did you do?"

"I finished fourth sir. Irina finished second."

"Who won," you ask, grunting softly as she jerks your cock.

"A girl called Ronnie. She's not here any more." A momentary anxious look passes across her face. You keep your own face stoic, recalling that Ronnie was the girl killed by a train last year.

"Was it all just hand jobs?" you ask with a lazy grin.

"Mostly sir, but once...it was a really hot guy...and I thought he'd donate more....so I used....my mouth," she looks at you shyly then looks down at your cock as her hand pumps at it. "Irina...I think Irina...fucked two of them...she's kind of a slut sir."

"Says the girl who's giving a handjob to a teacher to get advice on her technique," you laugh, making her face glow with embarrassment. Movement in the lather on your side window attracts your attention. You see a lush pair of breasts pressed against the glass, one nipple showing as the flesh undulates against the soapy window.

"And while you're jerking off the customer your friends provide a little 'inspiration'?" you chuckle. "Very effective technique Mikayla."

"Thank you sir," she purrs, stroking you faster and giving you a sultry smile.

"I've got to tell you that if you really want my opinion, you're going to have to show me what you can do with this," you say, reaching out one finger and touching her mouth, tracing around her soft full lips as you stare into her deep brown eyes.
