Make a run for the door

You have to get out of here! You swipe her hand out of the way and head for the door.

In your panic, you completely forgot it was locked! As you grab the handle and twist it, pull at the door and finally realise the situation, Mrs. North laughs.

"Come back here, you luscious little rascal. No man escapes me when I'm looking to use them for pleasure!"

She calmly walks over to you, grabs your legs and repositions them as far apart as they go. You don't dare look back at her or even move.

"But don't worry. I know how big I am, and how taking my cock can leave a boy's ass painfully gaping for weeks. Some boys had to learn that firsthand, but nowadays I always prep my conquests with lube first. Of course the gaping still happens, but there is less pain." She smiles at you, with an expression as if she is showing you a great kindness. In a second, your pants and underwear are on the floor, and she is caressing and spanking your asscheeks.

"It was kind of unfortunate how the boys would all have to stay home from school for so long after I had my fun with them just once," she continues her train of thought "when I really wanted to have them all here so I could simply send for them and have a boy to fuck in a matter of minutes!"

While talking, she had applied the promised lube to her cock, and it is now pressing against your tender opening. To your great dismay, your last line of defense is giving in, bit by bit.

"You will come back tomorrow", she tells you "and I will slip my cock into your ass without any lube or warning. I will have you between your classes, during lunch, and before you go home for the day." The first half of her cockhead is inside, but it feels like an entire fist.

"Oh, and if Ms. Nanci still wants you for herself, she will just have to find the time during class."

You gasp for air as the last bit of her head pops in, but Mrs. North keeps pushing. Another inch, then another. It's as if there is no end to them! You notice a bulge in your stomach, when Mrs. North says the scariest thing all day.

"That's almost half now..."

That's when it all breaks loose for you. The tears, the uncontrollable orgasm, the frantic attempts to run away (even though her cock has in fact lifted you off the ground and you are pressed up against the door). Your cum is being sprayed on everything in front of you. It is simultaneously the most scared and aroused you have ever been.

Mrs. North laughs and pets you on the head, before pushing the last part of her impossibly massive, ass-destroying cock inside you, as if it was nothing. The door is coated with even more of your cum, and Mrs. North commends you for it, saying the amount is quite impressive for a boy. She doesn't actually touch your cock.

She lets her own, legendarily-sized member get comfortable for a minute, there in the deepest reaches of your no longer private place. The feeling of fullness is unreal. When she wiggles her hips the tiniest bit, it sends waves of terrifying pleasure throughout your entire body. Your cock twitches, but has no more cum to give out.

She starts to slide back out, and it's as if you were floating in space, suddenly grabbed by merciless gravity - right in that moment when it begins to pull you, but you are still not moving.

Mrs. North stops when only her head is still inside, then lets gravity do the work of sliding you all the way down on her waiting cock. She lifts you up and does it again, and again. Every time, the ride goes a little faster, and every time she pulls you off her cock, you are overcome with an ever more intense longing for its return.

You don't realise it, but you're drooling and giggling in between breaths. Only one thing fills your mind: the pleasure of being invaded by this woman's cock. Right now, nothing else could possibly matter. You are addicted.

With you still attached, Mrs. North backs away from the wall and lets you lie on the teacher's desk, on your back. Just once, she pulls out her cock the whole way, to let you understand just how gigantic it is. Looking at it in its final form, you find there are simply no words, except a quiet whimper. She smirks at this, and thrusts it back in with little effort.

With her hands on your hips, she picks up the pace, and everything becomes a blur of bliss, moans and the loud sound of flesh slapping against flesh.

You don't know how long the two of you have been at this when she finally lets out an orgasmic yell and floods your stomach with her seed. It doesn't stop coming until you look several months pregnant. "For her, I wouldn't mind being -" You cut off the thought before it finishes, and fight the feeling of abandonment as your principal pulls out her cock. "Here", she says and plugs your gaping hole with a buttplug. "This way you can avoid making a mess in the halls."

"Th-thanks." You grab your clothes and put them on, but it proves difficult. Your hands and legs are shaking with exhaustion. "See you tomorrow!" Mrs. North radiates satisfaction.

Before you can leave on your shaking legs, Mrs. North puts her hand gently on your shoulder.

"Oh, I almost forgot. What was your name again? I need to know who to call for tomorrow."
