First Day 7

For so long, she'd been certain of her fate. She was dirty, used, tainted. Her only true use was providing what others wanted by satiating the heat filled desire that crept upon her constantly.

She was a rotten, dirty, filthy girl and she had no true worth. She was ashamed by how much she resented her former sister. And she was even more ashamed by how much she actually enjoyed surrendering to her desires, even if she was disgusted by the one she let fulfil those desires.

No matter how much she wanted a certain person to fulfil them instead, she could never tell him. She could never blemish the light senpai gave off. the only light in her dark world. She could never have him, and she wasn't ignorant to his crush on Rin Tohsaka. She was shamed that it made her resent her former sister even more. She had everything else, yet she even still stole his attention in the end?

But then, only someone as perfect as her former sister was could be with someone like senpai. Never her, never dirty, used Sakura.

When Shinji had come to her during class and told her what he wanted. She had obeyed. He wanted to curry favour with Kei Sota. He wanted her to have sex with him and give the younger boy a good opinion on her older brother. She had agreed easily without much resistance. She'd been holding back her latest heat for almost a week now, and the Crest Worms were running low on prana.

There wasn't a single person that didn't know Kei Sota at their school. Everyone was afraid of him. It was well known he was the leader of a large, powerful yakuza group, with incredible influence and wealth. Even the police were afraid to approach him and the teachers at school refused to bother him.

...Except Taiga. But the woman just amused the boy with her personality, so he let her get freebies.

Kei-kun was so different compared to her brother, and even senpai. He walked as if he owned everything around him. She'd watched the younger boy from afar from time to time, and she'd envied that about him.

He was tall, and despite his handsome looks, was incredibly intimidating because of his incredibly muscular build that made her older brother look thin and reedy beside him despite being a fit sportsman.

She could never have imagined he was actually a magus all along. One who like senpai lost his family in the Fuyuki Fire....the Fuyuki Fire that was caused by both her families and the 4th Grail War. And his past was even incredibly similar to hers.

The difference between them though. Was that Kei-kun was obviously far stronger than she could ever hope to be.

And...he wanted her. He knew about the Matou's, about the worms, and she even told him about how used she had been and how much of a dirty girl she was. Yet, he wanted her to be his. He even said he admired her!

She knew, that not even her noble senpai would want a tainted girl like her. Yet, how long had she dreamed for someone who would come and save her, accept her, want her even if she knew it was futile.

Yet... a miracle had occurred, and someone had appeared. Kei-kun had wanted to meet her, he wanted her for himself! And he was strong, so very strong. He was unlike her uncle, whom she loved dearly even to this day, so long after his passing. He radiated a strength that made her believe he could.

Was it weird to fall in love with him, even just a bit? Most likely, she was a weird girl. But she couldn't help it.

When he dropped his pants to the ground and exposed his manhood to her, Sakura swallowed a heavy lump and felt herself go wide eyed, shock piercing through the haze of heat and lust for the younger boy that had began to consume her.

His manhood, no his cock. It was massive, and intimidating. It was so big and thick it almost looked ridiculous, and utterly dwarfed that of anything she'd ever had in her before. "Oh my." She uttered in awe, her panties feeling absolutely drenched.

"Impressed?" Kei grasped his massive cock around the base and gave it a lazy stroke.

"It's so big." she said in awe. She licked her lips and gave him a heated, smouldering look filled with her desire for him, "I don't think it'll fit daddy~" he really liked her calling him daddy, his cock outright throbbed at her words and he took a half a step forward as if he was about to launch himself at her.

"Don't worry, It'll fit." he promised, and reached over with his free hand to grasp her by one of her ass cheeks, his fingers sinking into it greedily and pulling her over to him.

Her hands went to it, and it was so thick her hands couldn't even wrap around it fully, she had to grasp it with both hands. It was so heavy, and felt powerful in her hands, like a weapon! "If you say so, I'll believe you," Sakura smiled naughtily up at him, leaning up to poke her tongue out of her mouth and trail it up his chin a bit, "Let's do it daddy. Put it in me and make me scream your name." she mewled.

"Eep!" The plum haired girl eeped a second later as his hands moved form her ass to her thighs and hoisted her into the air as if she were a feather. Her stomach tingled and roiled. So strong, and manly!

But she wasn't idle, she reached down with one of her now free hands and her lilac panties to the side, exposing her dripping wet pussy to him.

And without a moments wait, he lowered her down and his thick cock head spread her pussy wide open, wider than it had ever been before. "Oh god~" Sakura moaned, she was consumed by heat and lust and her pussy spasmed as tiny little orgasms tore through her one after another as it his cock forced its way in and somehow, despite his sheer size, her pussy expanded around his cock to fit, yet wrapped around it like a vice.

She felt him press into her womb and in, and then she screamed as her whole body lit up with pleasure and her vision went black.

When it returned what felt like hours later, Sakura's gaze cleared and she found herself looking at Kei-kun, a smug, proud smirk on his face, while a bulge warped her previously fit and toned stomach.

Somehow, he'd fit it all in her. She wondered why for a moment, before deciding she didn't really care. Sakura felt all tingly, and numb, and fuller than she had ever been before.

"Back with me, huh?" Kei chuckled, before jerking his hips a bit and thrusting lightly into her.

A squeal left her mouth involuntarily as he pussy spasmed around the huge cock filling her up. "So good daddy~" she slurred out, barely able to form a coherent sentence, "You fill me up so good!"

He wasted no time then, using his grip on her thighs he lifted her up higher on his cock until only the head remained inside, then slammed inside her, hard!

Her large breasts bounced wildly on her chest and lightning surged through her body as he hit home, tearing another moaning squeal from her mouth. And then he made no attempts to slow down as he repeated the motion, and then again, and again, picking up speed each time until he was forcing the plum haired girl up and down on his cock at a blistering pace

"Oh god! Oh god! Oh god!" Sakura found herself screaming incoherently as he fucked like a beast, her eyes rolling up into the back of her head, "Your cock is so big daddy! you're fucking me so good! I'm going crazy! I'm cumming! I can't stop cumming!" she screamed, her tongue falling limp and dangling out from between her lips

He kept up a blistering pace of pounding up into her pussy and womb on each stroke for what felt like hours, before she felt his cock expand within her and he let loose with a roar.

More mana than she'd ever felt before poured into her like white hot magma and her body crazily jerked and spasmed around out of her control as she cummed her brains out.
