"You called for me, so I came... Wait, Shirone?"
"Mhm, it's me, Senpai."
Mitarai had been summoned to their usual "playroom," but what greeted him was a Koneko who looked nothing like herself. The difference was so striking that he almost questioned whether it was really her.
Her height and general aura remained the same, but one particular part of her had undergone a drastic transformation—enough to make Mitarai do a double-take.
"Big Sis taught me how to use Senjutsu, so I tried it out. What do you think? I made them as big as President Rias'."
She jiggled the alluring fruits pushing against her chest, the motion unrestrained since she wasn't wearing a bra. Even through her uniform, the exaggerated bounce was impossible to ignore.
"I always admired bigger ones, but wow, they come with their own problems. My shoulders are already sore, and my uniform's about to burst."
Koneko's outfit had been tailored for her usual frame, and with this sudden level-up, the fabric strained dangerously, seams threatening to split at any moment.
"I considered making myself taller like Big Sis too, but this way, I stand out more."
Most of the girls who had become Mitarai's women were tall. Exceptions like Asia, Shirone, and Ilulu existed, but the majority were well above average height, curvy, mature figures to match.
But now, Koneko had become something unique—a petite girl with an unexpectedly voluptuous body. A hint of smugness played on her lips as she spoke, knowing she could be something special to him.
"It's not just the looks—these feel packed with real meat..."
Without waiting for permission, Mitarai roughly grabbed her breasts through the uniform, squeezing with enough force to make a normal girl wince. But Shirone, being both a Yokai and a devil, didn't feel a thing.
He kneaded them greedily, testing their fullness, his palms brushing over her hardening nipples with each motion.
Koneko let out sweet, pleased gasps, submitting completely to his touch.
"Damn, you're still tiny everywhere else, but these are huge. It's so lewd."
"Nn~ Fufu~ I'm glad you like them, Senpai~ But standing like this is tough... Let's move to the bed, okay?"
She settled onto his lap, her small frame nearly swallowed up by his larger one as his hands continued their relentless assault on her big boobs.
While he groped and squeezed, their lips met in a sloppy, wet kiss, tongues tangling messily.
"Mmh~ Chuu~ Lick~ Nn~ Slurp, lick~"
As Takashi's hands worked her oversized breasts, his tongue demanded attention next. Shirone, like a cat fixated on a toy, watched it before eagerly sucking it into her mouth.
She alternated between deep, lewd slurps and playful twirls of her own petite tongue against his thicker one, their lips locked in a heated exchange.
"Nn~ Slurp~ Lick~ Ah~ Ah~!!"
Her nipples stiffened under his fingers, and every pinch or twist drew out breathy moans that escaped between their connected lips.
Unlike Asia, Shirone wasn't naturally submissive—but once she claimed Mitarai as her mate, she happily let him take the lead. She'd do anything he asked, but otherwise, she left the pace to him.
It was a mix of her personality and her Nekomata instincts, making her a different kind of pleasure compared to the other girls—one that Mitarai thoroughly enjoyed.
If he ordered her to, even in public, she would gladly perform something naughty without hesitation.
That's how thoroughly her instincts and reason had surrendered to Mitarai. As long as he didn't abandon her, nothing else mattered.
"Hamuu~ Nn~ Ahh N-No, I-I'm cumming~ I-I'm gonna cum! I'm gonna cum!! …nnnn~ Mmmm~!!!"
With a sharp cry, her body suddenly stiffened, then collapsed completely into Mitarai's arms, her entire weight going limp.
Her full breasts had grown even more sensitive lately — just a bit of caressing was enough to send her over the edge.
The heat pulsed from her hidden slit beneath her uniform skirt, a wet patch forming on her once pure white panties, turning them a darker, stained color at the crotch.
From her flushed, uniformed body rose the rich, undeniable scent of a horny female in heat.
Just like Akeno and the rest of Mitarai's harem, every time they were brought to climax by him, they transformed — not just in beauty but in their raw, lewd allure.
Their bodies instinctively evolved to better match his desires. Their minds and hearts weren't the only things he dominated — their very flesh bent to please him.
"You already came? Damn, you're one filthy little sex kitten."
"Mouu~… Senpai, you're just too good~!! Seriously, have some awareness. Right now, you're the kind of guy who can turn any girl into a mindless breeding slut! Girls like me end up cumming just from a bit of teasing."
"Huh… I still don't really feel it, but just looking at the numbers, I guess I am a bit of a playboy now… A year ago, I never would've imagined living a life this damn good…"
It had all started that spring, when he first met Rias.
More than half a year had passed since then. And truthfully, all he could remember was day after day of nonstop sex.
He'd gotten a taste of women during the peak of his sexual curiosity, and now he was completely addicted.
"Anyway, Senpai spacing out is fine and all, but… what do you want to do next?"
"Hmm… Since you have such massive boobs, how about a titfuck? But this time, vertical."
"Vertical titfuck…? That's where the girl lifts up her boobs to make a tight little valley, and the guy just slides his cock right in, right?"
"Exactly. There's lotion in the room, but… actually, your saliva might be even hotter~!"
"You really are a perv, Senpai~!! Alright, give me a moment to get things ready."
She slipped off her blazer, leaving just her dress shirt on top. She unbuttoned the first and second buttons, exposing her cleavage, then leaned forward and drooled into the narrow valley between her breasts.
The saliva foamed slightly — maybe from being swirled so long in her mouth — and the whole scene turned lewder than expected.
Her pale, smooth skin glistened as the spit traced down through her cleavage, but didn't reach her underboob — it just pooled warmly between her breasts.
She pressed both sides together, ~squish guchu~ massaging the flesh from the sides so her spit soaked deep into her inner titmeat, making it slick and perfect.
"All done! Here you go — your personal titfuck toy, Senpai~! I'm giving you my boob virginity too, okay?"
It was Koneko Toujou's first time doing a titjob…
