Start off with a squeeze

"I wondered when it was going to be my turn…"

Fran beamed down at the sissy between her knees, shuffling herself forward a bit in her seat so he would have easier access. Silvertongue's lesson for the morning was 'Cunnilingus 101', so the assorted members of the class blessed with female paraphernalia were riding high. Lizzy was somewhere further down the line, giggling down at Suzy's unhesitant approach. Jesse had got the distinct impression that the other femboy was not best pleased about this arrangement of pairings, so was just trying to get the lesson done with as soon as possible. In fact he also found it a little odd that their little group had only seemed to be paired off together so far, while the rest of the class had been mixed around a lot more. Was this some other purposeful scheme of the algorithm, testing the bounds of their new-found friendships… or just the coincidence of a truly randomised system?

Either way... Franceska, at least, seemed happy about her given partner.

"I've never actually had anyone girly down there before… It's always just cocks, cocks, cocks, slamming away… Even when they use their fingers or tongues, you know they're just viewing it as an extra sausage they've grown somewhere weird."

She grinned as she brushed a hand against Jesse's smooth and powdered cheekbones.

"But in here's the tongue that made even the demon headmistress blush… on your first day!"

Suddenly, her eyes bulged white… and her thighs slammed shut around Jesse's neck like an iron vice! The sissy panicked, struggling to free himself as he was pulled forward by the girl's spasming muscles. Until Silvertongue's face and voice appeared over Fran's shoulder, demystifying what had occurred.

"Slandering Madame Stanfield is not a punishment I hand out twice, girl… show some respect!"

The terrified-looking schoolgirl was obviously trying to turn her head and nod, but could barely manage it while the teeth-gritting electric shocks ravaged her body. Meanwhile, the sissy trapped between her legs was finding his face already grinding against the slight stubble of her sex; as the raw strength of those thighs was simply locked into full tension. It horrified him how little he could do against the unintended grip of this girl who, from all accounts, had been getting quite an impressive workout down here every day since she came of age. The sweetly-pungent scent of her pussy filled his nose as its growing wetness was rubbed against his lips. Guiltily, despite her obvious distress, all he was hoping was that she didn't wet herself from the overloading experience.

Neither of these plights seemed to particularly concern Silvertongue, the diminutive teacher who currently towered over them both. He kept the paralysing punishment going impassively. But something Fran had said clearly had intrigued him:

"Is that true, though? Did you get a chance to taste our glorious headmistress on your very first day here?"

Jesse did his best to nod meekly… afraid that even answering truthfully might get the shocks increased and his head severed from its shoulders by Fran's ridiculous strength.

Silvertongue just sounded distant and thoughtful, though. Looking down on this currently strangling student in a new light.

"And you're still here… Now that is impressive…"

He walked away, making it five steps before absentmindedly remembering to turn off the collar. Leaning down to give some advice to another pairing of students without a glance back at the gasping Jesse and Fran. As soon as the girl could she was smothering her partner with apologetic kisses, shooting the teacher dirty glances whenever his back was turned. But Jesse himself was more filled with anxiety about a past mistake, where he had clearly got away more lightly than even he had realised…

He got back to work lapping at Fran's dripping entrance as soon as he could. Determined not to waste any more lesson time and to try to replicate whatever had worked back then. If he was going to survive in this harsh world he needed to understand what it was that people valued him for… and he could start by giving his chastised friend here the gentler, more-effeminate orgasm she craved.
