Cum on Cotton

Miss Kathy cocked her head and grinned, "Yeah, that's got real artistic potential... I suppose you expect me to provide the cotton?"

"If you don't mind," John answered, stroking his cock as he approached her. "I was thinking your dress, specifically. I'll cum on it first, and then we can hang it up in the boy's room for the rest of the week with a sign offering extra credit to anyone who cums on it. That should demonstrate how willing the male student body is to debase themselves for a grade."

"But if my dress is in the restroom all week," Miss Kathy said, taking John's dick from his hand and massaging it herself, "what am I going to wear?"

John started to thrust into Kathy's fist as she pumped him harder. "Nothing, of course. That way they'll have plenty of reference material."

"Devious..." Kathy growled before dipping down to lick the head of John's cock. She teased her tongue around the edges of it, then nuzzled it against her warm, soft lips. Still rubbing up and down his shaft, Kathy clamped down on the very end of his dick and sucked like her life depended on it.

"Fuck," John muttered. "How is every teacher at this school such a slut?"

Kathy's lips popped off of him for just a moment, "You'd be surprised what it takes to get a teaching job these days. It's a very competitive field."

Before he could register the implications of that comment, Miss Kathy dropped down and sucked his aching balls into her mouth. Her free hand, meanwhile, slipped around started creeping toward his clinched ass.

"W-wait, what're you doing? I'm not really into assplay."

"Guys always say that, until they feel it!"

On the word "feel," Kathy's questing fingertip found John's puckered sphincter. The sensation was... interesting. It certainly wasn't the kind of pleasure he was used to, but it wasn't unpleasant either. His cock reacted positively enough; it somehow hardened even more, the purple tip throbbing against Kathy's pounding fist.

"Oh-oh god... I'm cumming!"

John's mind fogged over with a haze of pleasure, but Kathy kept her wits about her. She jumped back, moving John's cock in a steady arc across her chest to really paint herself with jizz. Even after everything he'd done today, he managed enough of a load to properly soak Kathy's dress, which clung heavily to her breasts and stomach.

John enjoyed the view as he caught his breath, then grabbed a scrap of paper and a pen. He wrote "Communal Cum-Rag, donated by Miss Kathy Clark. Cum on the dress and sign this sheet for extra credit in all of Ms. Kathy's classes."

Kathy moaned a little as she read the note, idly rubbing her nipples through her cum-soaked dress. "They're all going to be thinking of me as they do it..."

"Is that a problem?"

Wordlessly but a little reluctantly, Miss Kathy peeled off her dress, revealing her fully nude form beneath. As shocked as he was at the sight of her wild, untrimmed bush, the au naturel look suited Miss Kathy perfectly. She wasn't embarrassed in the slightest to be naked in the middle of her classroom; if anything, she seemed more comfortable now than ever. Miss Kathy called a student over, handed him her dress and John's sign, and told him to take them to the nearest boy's restroom.

Miss Kathy struck a few yoga poses to stretch her lithe, unconfined body before draping herself luxuriously across John's shoulders.

"I'm not supposed to tell you this," she whispered in his ear, "but I actually consider myself a nudist. The school board says I have to cover myself on the job, no matter how much I fight for a philosophical exemption, but the second I get home -- some days even in the car -- I strip down to my natural state."

John wrapped his arms around Miss Kathy's waist, pulling her into a kiss as he wondered whether his Fuck Pass could help with her plight...
