In The Spratul

Summary:

What if Foeniculum didn't stop Shiro doing exactly what she wanted with her brother?

Work Text:

“Okay, we’ll have to start again <3,” Shiro smiled, “But I bought a whole hour of only audio for our part of the livestream, so it’s worth it.” It had been tricky to convince Foeniculum to allow it, but she just opened her mouth, didn’t think, and let words fall out until it worked. “You’ll have to be a little quiet about what I’m doing to you, but surely even a pathetic virgin loser can manage that, right<3?”

Sora made a noncommittal noise, trying to force his brain to think through the mush and consider what was going on. His relief at Foeniculum’s intervention had lasted only a matter of seconds before Shiro eloquently and decisively negotiated the situation right back to her favor.

It was a good idea, there was no need for her to attend to the game personally, the battle units were mostly autonomous, and she had the advantage of the fortress, and this would keep the tips coming in, at least from the kinkier members of the audience, which were most of who would want ShiroxSora anyway, even if they could only hear the action.

The whip cracked outside the cage and pulled his gaze out of his thoughts and onto the very alarming object she’d gotten back from Foeniculum. “Brother, I know you’re socially maladjusted, but surely even the lowest shut-in knows that you’re supposed to answer questions.”

“Even a loser like me can be quiet,” his chuckle was slightly sardonic, having claimed quite the opposite at multiple occasions.

“I’m glad to hear that,” Shiro nodded, “Now take off your clothes. Don’t worry, I already know how unappealing you are <3.”

Sora bit back an objection, seeing the resolve unwavering on her mischievous smile. At least he had broad shoulders, that was one thing he didn’t need to be totally ashamed of. He pulled his shirt over his head and tossed it through the bars, correctly assuming that she’d want possession of his clothes outside of the cage. His face filled in with a dark blush, but he removed his pants and underwear too, looking down at the floor in front of his sister.

“You know what happens next, Brother,” she leaned against the bars, “I’ve seen it a million times in your porn. Now the loli gets to play with the worthless lolicon.”

“Do I really have a million-?” he wondered to himself, before shaking his head and pointing out a more relevant objection, “It’s already demoralizing to know that my precious baby sister has seen so much of my porn, but I can most certainly assure you that none of those stories involved,” he gestured to the object in her hand, “anything like that…”

“That’s because you hadn’t yet accepted what a pathetic, disgusting loser you are<3,” her answer came immediately, she reached through the bars and caressed his blushing cheek, “Real men might get to put something in the cute lolis, but you know your body is just a toy for me. Later I might use it to feel good, but right now, we’re making sure you know you’re place <3.”

He gulped audibly, shivering at her touch. Her hands were on him all the time, she moved his hands, pushed him around, patted his head, but none of that was when he was standing naked in a cage getting ready to lose the absolutely wrong kind of virginity. “And, um, indulge your worthless, total loser of a brother for a second, what exact place is that?”

Shiro’s hand drifted down, pushing on his shoulder, “Get on your hands and knees, spread your legs and try to relax your… special place,” she didn’t want Foeniculum to come complaining that she was having to censor too many words, “I got something to make it go in easier. Don’t worry, I’ll make sure Brother is comfortable <3.” She held up a bottle of lube to show him.

Sora felt his knees buckle and he shakily lowered himself into the right position. If he actually didn’t consent, it wouldn’t be possible for her to even touch him. But he knew there was no risk of that, no matter how afraid he was of anything- let alone something that big- going inside him, he wouldn’t even consider actually objecting. This was Shiro, there was no question about what he’d allow; quite simply, anything she wanted.

He wondered how his life had worked out quite so absurdly, that the first sexual contact he’d have with the most wonderful girl, would be this. He hadn’t necessarily intended to allow himself to do anything, perhaps ever, but certainly not now, certainly not this, he’d gotten in over his head and now it wasn’t up to him. But she wasn’t crying anymore, she was touching him and smiling.

Shiro squirted some of the bottle of lubricant on her hand and rubbed up and down the shaft of the toy, getting the silicone nearly dripping wet. She’d heard that virgin asses hurt more when penetrated and she didn’t want to hurt him more than necessary. She looked at his ass, cheeks parted slightly due to his position, hole a small pinkish pucker, nothing remarkable. Down further, between his legs were a small pair of testicles shielding his smaller penis nearly entirely from view. The little she could see from the side was erect though. He was responding just right.

She slowly pushed the head of the toy against him, slipping the slick silicone into the ring of muscle, parting it ever so slowly. Sora stifled a small moan, her touch nearly electric against his sensitive, virginal skin. He focused on keeping relaxed and breathing, it was not really what he expected, but he wasn’t sure if this was very much what he’d been afraid of or very much not. It didn’t hurt, she was moving slowly and carefully, the object was soft, smooth, and frictionless. He had to be honest here, he enjoyed it, but he wasn’t sure what kind of person that made him.

“It’s not gay if it’s your…” he mumbled a question.

Shiro laughed, sliding the toy all the way inside and resting her hand against his ass, “No, your loli sister touching you here isn’t gay… It is pretty pathetic that you like it so much though<3” she gave him a moment to adjust.

“I might be a pathetic loser, but I didn’t put the prostate in there,” his tone carried the mildest pout, even entirely broken, he kept a sense of humor.

“But Brother,” she paused for dramatic effect before pulling it suddenly out and thrusting back to bump against his prostate, “I hadn’t even stimulated that part yet! You’re just such a bottom that you like your asshole played with.” she hoped Foeniculum didn’t mind, “See, no girl will ever want a guy like that.”

She began pumping the toy in and out and he gave in to the sensation, shifting his weight back to his knees, then ducking his head down to cover his mouth with one hand and reach for his cock with the other. He did the second part slowly, giving Shiro time to stop him if she wanted to.

“Go ahead, this is how you belong. Jacking off kneeling in a cage while your little sister fucks your ass, that’s exactly the kind of behavior that suits such a lowly, pathetic pervert. No one but me will ever want you. <3”

It was never going to last more than a minute or two and the well placed, appropriate shame drove his hand faster; Sora came into the floor of the cage, crushing the “you’re right, no one else could ever love me,” moan behind his hand.

Shiro let go of the toy, walking around to crouch in front of the cage, level with his face. “If you accept that you belong to only Shiro, I’ll let you feel that every day. For right now, let’s keep you stretched while you think about it.” She petted his head, reaching to check the tablet for how the game was progressing.

Sora knew he didn’t need any time to think about it, there had never been any other real plan. He was always on Shiro’s side. But being left full made his already too sensitive cock harden again and he wondered if it was too much to hope that Shiro might touch it next, after she won the game.
