If We Can Do It Together, We Should
Prostatic fluid ran out of him in a thin, glistening thread. His tongue hung from his mouth the way a dog's does when it pants. A sound came from inside his belly that had no business being there at all — the wet, yielding noise of a dildo pushing somewhere far deeper than it was ever meant to go.
Terror surged through him. If this went wrong, his organs could tear. Reason screamed at him to stop, that it had already gone too far. But Katrina began to roll his hips, slow and deliberate.
The reason was simple. He wanted to feel that pleasure again. That was all.
It was a pleasure that eclipsed even the instinct to survive. He thought he was beginning to understand why people reached for drugs. The fear that his body might break down evaporated in an instant, and only the good feeling remained. Worry, anxiety, hatred, sadness — every sour emotion that cluttered the heart — all of it vanished, and his mind filled with nothing but bliss.
"More… more…♡"
Like an addict stretching a hand toward the next hit, Katrina rocked his hips. Every scrap of his attention locked onto the dildo driving into him. Even if someone had dumped him in the middle of a crowded boulevard, he would have kept rolling his hips, face radiant, utterly indifferent to the stares of strangers or whatever remained of his social standing.
"Hngh… haah♡"
His frail legs prickled and began to shake. He had never exercised in his life — walking itself was a chore — and the muscles that weren't there were already giving out. Katrina planted both palms on the floor. The pose looked like a frog gathering itself to jump. The sight of a noble young master, hunched in a frog squat, grinding his hips in a desperate hunt for pleasure, was almost comical.
"Pfft—"
Even Veronica, who had been watching with a sour expression, let out a snort of laughter. Katrina paid her no mind and kept moving. Something had been building down below for a while now — a cramped, urgent pressure. Something that felt like piss, or maybe not, kept threatening to come out and then didn't. He twisted his hips. He sped up. It wasn't enough. It only made the tease worse. It already felt good, but if he could just get that last bit out, it would feel even better. He wanted to empty every last drop of the lust he had bottled up for a week. One more step. That was all he needed.
Unfortunately, his pathetic stamina gave out first. Katrina toppled forward. He had been crouched, so when he fell the ass with the dildo still buried in it pointed straight at the ceiling. The dildo, which had been fixed to the floor, came unstuck with a wet pop and rose with his hips toward the sky. He looked like the corpse of a frog that had dried up in the summer heat.
Even then, still chasing the pleasure, he reached back with one hand and worked the dildo himself. But the pace was slower now, the thrusts heavier, clumsier. He lifted his head and looked up at Veronica.
"Please help me…"
"And do what, exactly?"
"I was wrong, so please — fuck me. Please…"
Veronica's face slowly twisted. Katrina assumed she was angry and shrank in on himself. She wasn't angry. She had been waiting for him to ask.
Veronica stood and walked around behind him.
"So it doesn't satisfy you unless your sister fucks you. Is that it?"
"Yes… it has to be you… Please fuck me♡"
"If you beg that prettily, what's a sister supposed to do but indulge you?"
"Haaah… ooh♡"
Veronica yanked the dildo out of his ass in one rough pull. Even after it was gone, his hole stayed open, the inner flesh on full display. It flexed and fluttered, throwing a tantrum, begging to have the dildo back. Veronica shoved three fingers in at once, and they sank in without the slightest resistance.
"Hah — I suppose we ought to stop calling this an asshole. It's a pussy now."
"Y-yes… Please, hurry — put your cock in my asspussy…"
"…Did you spend the whole week studying how to talk filthy?"
The words nearly gave her a hard-on she didn't even have. Veronica hiked up her slip, fitted a dildo into the strap-on, and took her place behind him — a tall, threatening silhouette. She dragged the shaft up and down the cleft of his ass. There was no physical sensation from the toy itself, but the psychological rush made her body shudder.
"Don't tease me — just put it in already…"
And when the other person was throwing a fit like this, even shaking their ass for her, there was no holding on to reason. Veronica lined herself up and drove her hips forward.
A wet, heavy slap.
"Kyah♡?!"
Lightning struck inside Katrina's skull again. No — harder than before. Like being hit by a real bolt, his breath seized in his throat and his whole body shook like a leaf in a gale.
"Don't worry. I'll fuck you like a dog."
Veronica let out a satisfied sigh and rolled her hips. Every time she moved, it felt as though the organs in his belly were being stirred. Looking down, he could actually see his lower stomach bulge in time with her thrusts.
"W-wait — just a second—"
"What? Frightened now? You're the one who asked for it."
Genuine terror that his guts might rupture made him reach back, but he couldn't touch her. And to her, his resistance looked like another tantrum — she cracked him across the ass.
A sharp smack, and his ass rippled like pudding. A red handprint bloomed on the white skin. She paused only a moment, then started moving again.
"Hehk, hehk— hiiik…♡"
This was a different dimension from doing it alone. Pleasure was being force-fed straight into his brain. Moans leaked out of his mouth along with the drool. There had been a time he'd thought the women in dirty videos were all acting. Well, of course he had — back then he hadn't known it could feel this good…♡
His breathing turned ragged. He could barely draw air. His eyes unfocused, vision going soft and blurry.
"Please let me come— let me come…!"
Words that hadn't passed through thought spilled out of his mouth. Crude, filthy things that the version of himself with a working brain would have recoiled from. The person saying them had no idea what he was saying. He just threw his body into the pleasure and begged for more.
He pressed his belly to the floor and hiked his ass even higher. His muscle-less, flexible body bent into a soft curve, like a female in heat.
"Haang, nngh— it feels so good…♡"
The new angle let the dildo punch even deeper. Every stroke of her toy sent a female kind of pleasure racing up his spine to slam into his brain. He wanted to savor it a little longer, but he couldn't hold on. Ah — I'm coming…♡
"……♡!"
That was the last thought before Katrina came, spectacularly. He clung to a mind gone hazy with climax and dragged in ragged breaths. From the chastity cage, a liquid that might have been precum or piss dripped onto the floor. The arms holding up his upper body gave out, and he collapsed flat. The ass he had been holding so high slowly sank toward the ground.
A wet schlick—
"Hiiit…♡?!"
It was the sound of a cock pulling out of a pussy — and his asspussy spat the dildo free. Even that sensation felt good; his hips twitched and trembled.
"So the saying's true. Neglect the front, and the back grows sensitive."
Veronica pushed her damp hair back as she spoke. She was soaked in sweat herself, clearly spent. She drained the water glass on the table, then picked up the key. She rolled Katrina onto his back. The chastity cage was slick with some unidentifiable fluid.
"I promised, so I'll take the cage off."
A click, and a rush of freedom hit his cock. Liberation from the chastity cage that had tormented him for a week. And yet… he felt nothing. He had waited this entire week for this exact moment. He should have been happy. So why… does it feel like nothing at all?
If anything, he wanted more of what he had just felt. That pleasure that made his eyes roll back and drool run down his chin.
"W-wait. Sister."
Katrina caught her as she started to stand. Veronica turned, puzzled.
He'd stopped her. Now what was he supposed to say? He hesitated, then opened his mouth slowly.
"Y-you're pathetic, sister…"
"What…?"
"I'm not satisfied yet. And you're already finished…?"
Lying on his back, Katrina spread his legs in a V and rolled his hips. He had chosen to throw her own tactics right back at her. No long speech needed — just a light tap on the other person's pride. Of course, her goal was to conquer him, and his was to provoke her, but still.
"…I'm going to make you regret those words."
"If you think you can, go ahead…♡"
It landed exactly the way he'd intended. That was a win, wasn't it?
Veronica's face twisted as she climbed on top of him. Her eyes burned like she might devour him on the spot. His heart kicked, and his prostate started trembling all over again. Katrina answered by kissing her first.
Veronica, eyes gone wild, didn't hold back. She shoved the dildo in and started moving her hips. What followed was too much to call sex — it was mating, and the night only grew deeper around them.
Tonight was going to last a little longer than expected.
