Anonymous asked: When Shirou stayed overnight at his girlfriend's house, he decided to sneak into her room and give her a little surprise.
At first, she seemed to resist, but Shirou knew Ruby well enough to know that she really enjoyed these kinds of games and might even get angry if he stopped, so he went ahead and fucked her as hard as he could until the sun came up and her stomach was round enough to be mistaken for a woman pregnant with quintuplets.
The next morning, Ruby decided to burst into her mother's room to ask if she had seen her boyfriend. The light filtering through the door revealed Summer Rose's face, lost in pleasure.
Oh, it seemed she had the wrong room.
And the wrong Rose.
Oops?

When Shirou visited his girlfriend's home, he'd expected Summer, Ruby's mom, to insist on them not sharing a room.
What he hadn't expected, was Ruby being completely alright with this rule.
He'd been ready for whining and begging, and maybe even outright yelling if things escalated. He'd been so not ready for Ruby to simply nod and agree to her mom's decree that he'd almost completely missed the byplay.
He'd stared at Ruby, shocked. It wasn't like he would make a big deal of it- after all, he could go a couple of nights without sex. He just didn't think Ruby could.
But then, as they all went to their separate rooms, Ruby had shot him a wink, before closing the door behind her, and Shirou understood.
Of course. Of course, Ruby wasn't actually fine with this rule, nor did she respect her mother too much to go against her.
She simply was planning on Shirou breaking it.
Of course.
Ruby was lucky she was so cute, or else Shirou might've been annoyed at needing to deal with the unplanned situation.
But he also wasn't about to leave his girlfriend out to dry when she was expecting him.
So, all he could do was sneak out of his room, into the still unfamiliar house, and enter Ruby's room to fuck her.
All of this without waking up the other Huntress in the house, whose room was sitting right in front of Ruby's, on the other side of the hallway.
Easy.
Thankfully, he'd just walked down this hallway an hour ago, and he'd made sure to notice where he'd been stepping.
None of the planks he'd stepped on had creaked, so all he had to do was retrace his steps.
Which he promptly started doing, carefully holding his arms to the side as he did his best to step on the same planks he'd previously used. Which of course, would be a lot easier had he not been in nearly pitch-black darkness.
Thankfully, his steps remained silent until he reached Ruby's room- which he knew was correct from his number of steps. Now, he just had to slowly turn, and-
Shirou didn't hiss as he lost his balance slightly mid-turn, spinning on his heel for a moment.
It took all of his concentration not to slam his foot down to stop himself. Instead, he reached out- and grabbed the doorknob to Ruby's room, and he allowed himself a quiet sigh.
He didn't knock, of course, nor did he announce himself in any way other than turning the knob and stepping inside.
The room was just as dark as the hallway, of course, and even with the door closed behind him, Shirou didn't feel comfortable speaking.
Ruby was lying in bed, underneath the covers, sleeping?
Shirou blinked, before a smirk pulled at his lips. No- she was probably pretending to sleep in case her mom checked up on her.
This might be the time to pay the girl back for putting Shirou through this then~
Just as silently, Shirou began approaching the 'sleeping' girl, carefully feeling the edge of the bed with his fingertips, but not climbing into it.
Not yet.
He knew exactly how to announce himself after all~
Silently, Shirou slipped out of his pajama bottom, revealing his throbbing cock, and silently inspected Ruby's form in bed.
He couldn't see clearly through the darkness, but he could see enough to approximate how her body was resting.
Meaning that, when he made his move, flipping up Ruby's covers and jumping into bed, he knew exactly where to thrust to punch right into Ruby's womb.
Of course, at the same time he did that, Shirou made sure to use the flipped covers to muffle Ruby's squeal of pleasure as she came instantly around his rod to make sure Summer wouldn't wake up.
Sadly, that meant that he wouldn't get to see Ruby's lewd ahegao as he started pistoning into her pussy with the ferocity of a slightly annoyed boyfriend, but that was a sacrifice he was more than fine with.
Though, perhaps he'd underestimated the effect of surprise.
He'd planned to only muffle her original cry of pleasure- once she realized what was going on, surely she would work to silence herself?
But no. For some reason, Ruby was not calming down. If anything, she was thrashing more and more, her lewd moans of pleasure not quieting down even a little bit as she came more and more around his cock, and her pussy was gripping him! It reminded Shirou of the first time the two had fucked.
Damn. Maybe he should surprise Ruby like this more often~
Shirou grinned as he grabbed her hips, flipping her over so that her uncontrolled vocalizations could be silenced by her pillow, and began slamming into her womb, making her squeal as he made her womb bulge obscenely against her stomach as he punched into it again and again and again-
Only for him to suddenly gasp as his cock head slipped past her cervix, making Ruby suddenly fall silent.
If it wasn't for the way her pussy was wrenching at his cock like it was trying to rip it off while spraying her juices all over his balls, he'd think she died.
But honestly, he understood the reaction. The couple had been trying for weeks to breach Ruby's resilient little cervix to no avail, only for it to suddenly loosen like this, allowing him to truly sink balls deep into his girlfriend.
Normally, Shirou would pull Ruby off her pillow to properly celebrate.
But as it stood, he was far too horny to even think of stopping.
If anything, he was more motivated than ever to flood Ruby's babymaker and breed her once and for all~
Which he did in short order. And then he did it again for good measure. And then once more just to be safe.
And once he'd cum three times, well, there was no reason to stop there, was there?
So he did it again. And again. And again.
He pumped Ruby's womb so full of cum she looked like he'd done this to her eight months ago, and given her triplets.
But just to be safe, he did it again-
"Mom? Do you know where Shirou is?" Ruby asked as she opened the door to her own room.
Where Shirou was currently fucking Ruby.
Or so he thought.
The two teenagers froze as their eyes met.
Outside, a bird sang to greet the rising sun.
And a completely mind-broken Summer answered it with a cum-drunk giggle.
A beat.
"…You better still have some left for me," Ruby pouted, and Shirou sighed.
"What a needy girlfriend I have."
But he eventually found that he did, in fact, still have some left for her girlfriend.Hopefully, Ruby would get pregnant too, because if Shirou bred her mom before her, she would never let it go.
