Anonymous asked: Shirou knew Asia was naive; she'd been raised almost in isolation in a church, after all.
But there was a huge gap between that and asking her what sex was and why Issei seemed so obsessed with it—a gap he didn't think was possible.
So, well, no one could blame him for using his enormous cock to fuck this airhead blonde until she passed out to teach her, right?

“Shirou-senpai, what’s sex?” Asia’s soft voice asked one day, making Shirou choke on his spit.
“Wh- Excuse me?” He asked, blinking tears away as he looked down at the tiny blonde, who was fidgeting in her seat.
“Uhm- I was wondering if you knew what sex is…” Asia asked again, dispelling any hope that Shirou had simply misunderstood her.
Shirou barely heard her explanation as to the reason for her question, still trying to grapple with the fact that Asia didn’t know what sex was. He knew she had been raised sheltered, but surely even the Church needed to teach her what sex was?
How was Asia supposed to remain a ‘pure maiden’ if she didn’t even know what that meant? Didn’t the Church worry that Asia might get tricked because of her naiveté?
What if some unscrupulous man took advantage of Asia’s ignorance to fuck her tight little body into a coma, breeding her stupid without her even knowing what exactly was happening to her? What if they taught her something completely fictitious, like ‘A man’s worth is measured by the size of his cock’, or that ‘When you make a man hard, it’s your duty to take care of their lusts with your body’?
What if someone lied to her about the importance of sex? Taught her that sex meant practically nothing, and that anyone could just walk up to her and demand to fuck her mouth, and the polite thing to do was squat in front of them and stick your tongue out for them to enjoy? Or taught her that you could only have sex with your soul mate, before breeding her silly, making her believe that the fact that her slutty pussy got pounded into mush meant they were destined to be together forever?
Or maybe teach her that anal sex meant Asia was still a virgin, before training her into a buttslut who could cum in seconds from getting her guts stretched out? Train her asshole until she could easily take any cock and be made to cum her brains out with a good grope?
Maybe trick her into selling her virginity in an auction under the guise of charity, making Asia raise money by selling something she didn’t even know she was supposed to value?
Hell, was she even a virgin anymore? Did the Church never teach her what sex was so that they could fuck her sweet little pussy at all hours of the day without ever telling her what was going on?
“Shirou-senpai?” Asia asked, making Shirou blink as he focused back on the girl in front of him, ignoring the way his cock was practically tearing a hole through his pants as he looked at her.
She was completely oblivious- and not just that, but also naive, and far too trusting.
Anyone could take advantage of the Church’s failure to teach her.
Anyone…
Shirou smiled kindly at the blonde. “I can teach you what sex is, sure.” He said simply, and his cock throbbed as Asia’s face lit up with glee.
“Really!? Thank you, Shirou-senpai!” She said, not even asking why he was pulling her into his bedroom.

“C-CUUUUMMIIIIIIIIINNGSSSSSHHHH!!!~” Asia howled as she was forced to cum around Shirou’s cock once more. Her nude body was covered in sweat and cum, highlighting the bulge Shirou’s cock made in her stomach while he plowed into her missionary style.
It seemed appropriate.
Her blonde hair was strewn all about on Shirou’s pillow, her blue eyes rolled into the back of her head, her mouth hanging open as her pink tongue lolled out, drool and tears staining her cheeks.
Her pussy was drooling femcum all over his bed sheets as he fucked her into the mattress, not to mention the copious amounts of cum he’d already shot into her and were now overflowing out of her filled womb.
Anyone could’ve done this, but thankfully, Shirou was the one given this opportunity~
It had taken barely any effort at all to get Asia in this position, reshaping her pussy into his cockholster under the pretext of teaching her about sex. And Shirou was teaching her.
Oh, he was teaching her. Shirou grinned as his balls churned, before unloading yet another virile load of cum into Asia’s fertile pussy, making her howl in pleasure as she came her brains out again.
By the time Shirou was done with the nun, Asia would know exactly what sex was, and why it was the most important thing she could be doing.
And for the first time in his life, Shirou found himself grateful for the Church’s actions.
They’d given him a pretty tight slut to break in after all~
