You explain how things will go

You enjoyed a lovely time in the teacher’s break room, they all adored your pasties! It’s just a shame you couldn’t infect any of them. They’re all sissies already!

When class reconvenes you explain.

“Alright students I want to be totally clear with all of you. Everyone in my class is going to be a sissy.”

There are some confused looks in the class and one of the slower bois in your class raises his hand to ask “Um, what do you mean?”

You smile warmly at him as you make your way to his desk. You offer him your hand and lift him to his feet then guide him to the front of the classroom. You turn him to face the class and stand behind him setting your hands on his shoulders. You lift his shirt and squeeze his pecs
“Charles being a sissy means you will have a nice plump rack and…”
your hands slither down his body dropping his trousers so you can cup his cage and his balls
“a big jizz spurting cock.”

You’re on a roll now so you massage his balls as you address the class “I’ll infect you all. Any ability you all had to resist me is quickly fading.” You delicately bend Charles over the desk of a sissy in the front row and slide your see-through panties down your thighs. You sandwich your cock between his cheeks and slowly fuck the cleft of his ass as you moan and continue
“You might think you can escape me, but you are wrong. You’re in far too deep. You may not even realize it yet.”
With another thrust you have Charles dribbling in his cage. You lean back and stand in front of the class letting them all get a good look at your full erection.

“Each of you is going to surrender to me completely.
Then when you’re ready and you want nothing more than a thick load of my sissy cum…
I’ll take you to the absolute peak of ecstasy…”
The entire class is so silent you could hear a pin drop.
“And infect you… during the most intense orgasm of your life!”
