Day 2: Classroom 3D

Harry Potter never thought that finding the way could be this hard. With a hundred and forty-two staircases, a lot of doors, and no guide (the ghosts didn't help), at Hogwarts. When he and Ron Weasley tried to **** their way through a door, they got into trouble with Argus Filch, who thought they're trying to break into the forbidden Third Floor Corridor. Luckily, Professor Quirrell happened to pass at that time, thus creating a distraction. Harry and Ron ran in opposite directions, and judging from the footstep, Harry thought he has managed to escape.

But when he stopped to breathe, he realized he's wrong: the caretaker may not chase after him, but he sent Mrs Norris to tail after Harry. Sooner or later Filch would come.

Harry hasn't learned any magic yet, so in the **** situation he tried the only spell he knew:

"Neque Curriculum!"

He instantly vanished, then reappeared in a classroom. There was a female student who was cleaning the room.

"Hey, how do you enter here? Don't you see the sign 'Cleaning In Progress' outside?"

"...Pardon me, I'm hiding from Mrs Norris."

"Oh, you have trouble with Filch, don't you? Then you're safe here. By the way, I'm Piper Macmillan. Who are..." she stopped when seeing the lightning scar on his forehead, "You're Harry Potter!"

"Oh," said Harry. "I mean, yes, I am."

Piper smiled: "Then in exchange for the cover, I demand one thing from you."

Harry felt a deja-vu.

"I want to mate with you. Luckily we already have a bed here."

"Wait, wait, wait. Why do you want to mate with a guy who you just meet? And why does a classroom have a bed?"

"First, you are Harry Potter. A lot of girls will pay tons of Galleons to have a one-night stand with you. Second, this room has been used as storage, but professors decided to change it back, and my task is to remodel it. We can do anything in here for a day."

Harry was speechless.

“What are you waiting for Harry? Get that dick out and get over here and fuck me.”

Harry reluctantly accepted. When he just finished putting his pants down, Piper was already naked, gasping with awe as his drooling boner sprung out into the open.

“Wow! What a weapon you have on you. I need such a big dick in my cunt and I need it now.” She climbed excitedly onto the bed. Her cunt was now raised high enough so that it hung above Harry's cock.

She then tried to let it in, but when the cock rubbed her clit her muscle control became chaotic. After trying several times she gave up and let Harry take the active role:

“I’m already wet as hell, so you just stick that throbber right in.”

With his hands holding her thighs, Harry placed the tip right against the soft flesh of those pussy lips and drove in.

“Aaaaaa...oh god!” Piper groaned, sinking deeper and deeper. Her inner walls constricting on his flesh, as if she was drawing him in and sicking him dry.

“God that’s deep, it’s good to fuck at right angles, that always allows for deeper penetration. Now your cock’s inside my warm, wet fuck hole. Now let’s see what you got!”

Harry began to slide in and out of Piper, stretching her pussy. “How are you so tight?” He groaned as he ramped up his thrusting, transforming from gentle to a fervent frenzy. “You’re the tightest I have ever had.”

"It's the same. Your thing is the best cock I ever tasted. I never feel so filled."

They kept increasing the pace when kissing and caressing each other. In the end, Piper was the one who reached orgasm first. Her love juice squirting out, wetted the bedsheet.

Harry laughed: "Did this count as my victory?"

"Don't be so cocky, I'll make you cum right now," Piper applied more pressure and Harry could feel his cock touch her uterus.

"Hey, you are playing with fire. If I cum now it would spray directly into your womb. Are you sure you want to continue?"

“Go ahead, cream this nasty pussy if you can!”

“Aaaaaaaaagh!”

Harry slammed into her one last time, felt his cum charging out of his balls, going through his cock into the confines of her cunt, filling her up with his impregnating seed. Finally, when he pulled his cock out, his cum barely dripped out from her pussy, meaning two things: one, he released a very big load inside her, and two, his cum contained so many sperms that it became as thick as glue. There was no way a woman's immune system could kill the entire amount.

“Are you trying to knock me up? Mmm, I can feel all that lovely sperm swimming in my pussy.” Despite saying that, Piper's tone indicated that she didn't worry at all.

They both took a rest to recover. Harry checked and smiled when seeing the message:
