The guest room in Katsuki’s mansion had become Izuku’s sanctuary, a soft haven of pastel walls and plush bedding that smelled faintly of lavender. Night after night, the twins insisted on sleeping with her—Kenzo on one side, Haruto on the other, their chubby little bodies curling into her warmth like she was their lifeline. Izuku didn’t mind; in fact, it filled the emptiness in her chest, that maternal ache she’d never known she had. Now, widowed and adrift, these boys were her anchor, their gurgles and tiny fists clutching her tiny sleep dresses making her feel needed, loved in a way Mr. Bakugou never had.

This particular night was no different. Izuku had slipped into a minuscule nightie—a whisper of pink silk that barely qualified as clothing. The top was a halter style, thin straps over her shoulders, the neckline plunging dangerously low over her massive breasts, which swelled even more with her constant lactation. The hem skimmed the top of her thick thighs, leaving her plump ass and pink fat pussy barely covered if she shifted wrong. She felt comfortable in it, the fabric cool against her white skin, her pink lips humming a lullaby as she settled the babies down. Kenzo, with his tuft of hair and mischievous eyes, snuggled into her left side, while Haruto, quieter and dimple-cheeked, claimed her right. They drifted off quickly, their breathing syncing with hers, and Izuku soon followed, exhaustion pulling her under.

In the depths of sleep, the nightie betrayed her. One strap slipped off her shoulder, the fabric tugging down as she rolled slightly. Her full, heavy tits spilled out completely—pale globes topped with rosy nipples, already beading with milk from the pressure of her dreams. The room was dim, lit only by a nightlight’s soft glow, but the air was warm, charged with the quiet intimacy of the moment.

It was Kenzo who stirred first, his little nose twitching at the scent of her milk. Half-asleep, instinct took over; he wriggled closer, his chubby mouth latching onto her exposed nipple with a soft, hungry suck. Milk flowed instantly, warm and sweet, and he drank greedily, tiny hands pawing at her breast, his eyes fluttering in contentment. The sensation pulled Haruto awake too—seeing his brother nursing, he let out a soft whine and mirrored him, latching onto Izuku’s other boob. Both boys suckled hungrily now, their pudgy cheeks hollowing with each pull, milk dribbling from the corners of their mouths as they fed like it was the most natural thing in the world.

Izuku stirred slowly, her long lashes fluttering open. At first, confusion clouded her beautiful face—then realization hit. She stiffened, her white skin flushing hot as she looked down at the twins latched to her fat tits, drinking deeply. Tears welled in her eyes, not from shame, but from an overwhelming rush of emotion. “Oh, my sweet babies,” she whispered in a soft baby voice, her pink lips trembling. “You’re so hungry, aren’t you? Auntie Izuku’s got you… shh, drink up, darlings.” She clutched them closer, one arm around each, her flat stomach pressing against their little bellies as she cradled them. The maternal feeling surged through her, warming her core, her pink fat pussy clenching involuntarily at the intimacy. She’d never felt so needed, so right—like this was what her body was made for.

The door creaked open then, a sliver of hallway light spilling in. Katsuki stood there, tall and shirtless in low-slung sweatpants that hugged his muscled thighs, his handsome face soft with concern. He’d come to check on the boys, as he often did in the quiet hours. But the sight froze him—Izuku in the middle of the bed, her tiny dress bunched around her waist, her massive breasts fully exposed, swollen and glistening with milk as his sons nursed hungrily. Kenzo’s mouth worked rhythmically on one nipple, Haruto’s on the other, their chubby faces buried in her soft flesh. Katsuki’s breath hitched, his cock stirring unbidden in his pants at the erotic, forbidden vision—her white skin glowing, pink lips parted in surprise.

Izuku stiffened too, her eyes widening in mortification, tears spilling over. But she couldn’t move, couldn’t hide— the babies were still latched, drinking with contented sighs. “K-kacchan…” she whispered, flushed crimson, her voice shaky.

Katsuki turned away quickly, his broad back to her, muscles tense. “Sorry,” he murmured, voice rough with a mix of embarrassment and something deeper. “I just… wanted to check on them. Make sure they’re okay.”

Izuku’s heart pounded, worried he’d think less of her—that this sweet, accidental moment made her the slut Kaina always accused her of being. “I… I woke up and they were already… drinking from me,” she explained hurriedly, her baby voice turning anxious. “I didn’t do this on purpose, Kacchan. Please don’t be mad.”

He glanced over his shoulder, careful not to look directly, but his eyes betrayed him, flicking to her for a second. “Mad? Deku, no… Kaina never fed them like this. They were always bottle-fed. She said it would ruin her figure.” His tone held a bitter edge, resentment toward his wife bubbling up.

Izuku’s tears flowed freer now, her kindness twisting into sorrow for the boys. She held them even closer, their suckling sounds filling the room as milk continued to flow. “Oh, poor darlings… that’s so sad. But I’m here now, right? I’ll feed them. Whenever they need it.” Her voice was maternal, fierce in its protectiveness, her pink lips brushing their foreheads.

Katsuki turned back fully for a moment, unable to resist—his gaze locked on her fat tits, the way they heaved with each breath, nipples hard and leaking around the babies’ mouths. Izuku flushed deeper, feeling exposed, vulnerable, but also a thrill at his stare. Their eyes met, heat crackling between them. “Goodnight, Deku,” he said finally, voice husky, before slipping out and closing the door.

The room fell silent again, save for the soft nursing sounds. Izuku rocked the twins gently until they unlatched, sated and sleepy, milk smeared on their chubby cheeks. She tucked them back in, pulling her nightie up with trembling hands, her body buzzing from the encounter. Sleep came fitfully, dreams laced with Katsuki’s intense gaze.

Over the following days, the mansion thrummed with unspoken tension between Katsuki and Izuku. It started subtly—a brush of fingers when he handed her a coffee in the kitchen, his large hand lingering on hers, sending sparks up her arm. She’d flush, her white skin turning pink, mumbling thanks in her sweet voice. Or in the garden, as she played with the twins in a tiny sundress that rode up her ass when she bent over, Katsuki’s eyes would darken, tracing the curve of her flat stomach, the jiggle of her big boobs. “You look… happy out here,” he’d say, his kind tone laced with hunger.

Izuku felt it too—the way her pink fat pussy ached when he was near, her milk leaking more when his muscled arm brushed her side during family dinners. She’d catch him staring at her pink lips as she cooed to the babies, or the wet spots on her tops from lactation, and she’d bite her lip, torn between shyness and desire.

Kaina remained oblivious, her rude self absorbed in shopping trips and spa days, barely glancing at the boys. She didn’t know about the breastfeeding—Izuku made sure of it, feeding them only when Kaina was out or asleep. In hidden moments, Izuku would slip away with the twins to her room or the nursery, lifting her tiny top to let them latch. “Shh, my loves, Auntie’s got plenty,” she’d whisper, eyes closing in bliss as they drank, her maternal instincts in full bloom. It became their secret ritual, the boys thriving on her milk, growing chubbier and happier.

But the tension with Katsuki built like a storm. One afternoon, as Izuku bounced Haruto on her hip in the living room—her micro-shorts wedged between her ass cheeks—Katsuki entered, his suit jacket off, shirt sleeves rolled up over his forearms. He reached for Kenzo, their bodies close, his chest brushing her arm. “You’re amazing with them,” he murmured, his breath hot on her ear. Izuku shivered, her nipples hardening under her thin top, milk beading through. Their eyes locked, a forbidden promise hanging in the air.

Nights were the worst—or best. Katsuki’s checks became more frequent, always at the door, but his gazes lingered longer. Izuku would smile sweetly, her body on display in her slutty sleepwear, heart racing. The lines were blurring, desire weaving through their kindness, threatening to unravel everything.
