The next morning hit Kook like a truck—sun streaming through the massive windows of his bedroom, birds chirping in the garden outside. He groaned, rolling over, his body still buzzing from last night. That image of Tae, all naked and innocent on the beach, kept replaying in his head, making his morning wood even harder. Sana was already gone, probably off to some brunch or shopping spree, not that he cared. He threw on sweatpants and a tee, padding down the hall to Haneul’s room, heart already softening at the thought of his little guy.

He pushed the door open quietly, and fuck—there she was. Tae, in nothing but that tiny pink bra from the shop, the lace barely holding her massive tits in, nipples poking through like they were begging for attention. And the thong? God, it was a scrap of fabric, riding up between her fat ass cheeks as she swayed and danced around the room, Haneul giggling in her arms. Her hips rolled to some imaginary tune, ass jiggling with each step, that pink pussy outlined perfectly through the thin material. She was humming softly, twirling, her long hair swishing over her bare back. Innocent as hell, but looking like pure sex.

Kook froze in the doorway, cock instantly hardening, straining against his sweats. “G-good morning,” he managed, voice rough, eyes glued to her curves.

Tae spun around, beaming, not a hint of shyness. “Kook! Morning! Look, Haneul’s awake and happy. We’re dancing—it’s fun!” She bounced the baby gently, his chubby hands patting her tits through the bra.

He swallowed hard, stepping in, trying not to stare at how her boobs bounced with her. “Yeah, uh… looks fun. But Tae… where are your clothes? The ones we bought?”

She tilted her head, still swaying. “Oh, these? The bra and thong? Maria said they’re under-clothes, but they’re comfy! The big ones feel too tight, like I’m trapped. Down in the sea, we don’t wear anything. Feels free like this.” She giggled, twirling again, ass flexing.

His cock throbbed, pre-cum already leaking. “Tae, you can’t… you can’t let others see you like this. Sana, the staff—they’ll scold you. Or worse. Humans… we cover up. It’s not safe.”

Her eyes widened, pout forming, poor thing looking scared. “Scold me? Like yell? Oh no… I don’t want that. Okay, I’ll wear more. But just for you and Haneul, it’s okay, right?” She batted her lashes, innocent but flirty without knowing.

He nodded, exhaling shaky. “Yeah, just… around me and the baby. Now, come on. Let me show you the routine.” He took Haneul from her, the baby cooing happily, and laid him on the changing table. “First, nappies—diapers. He gets messy.” Kook demonstrated, unfastening the old one, wiping gently, powdering those chubby thighs. “See? Gentle, like this. Don’t want rash.”

Tae leaned in close, her tits brushing his arm, watching intently. “Oh, he’s so adorable. Cute! Like a little sea slug.” She giggled, taking over when he handed her a fresh diaper. “I got it—tape here? Yes!”

“Good job,” he praised, voice low, watching her ass as she bent over. “Now, feeding. He’s on formula—warm bottle, test on your wrist.” He mixed it up, showed her how to hold Haneul, the baby latching onto the nipple greedily.

Tae’s eyes sparkled. “He’s hungry! Look at him suck. Aww, my little squishy.” She rocked him, humming again.

Kook’s heart twisted—seeing her like this, so natural, so loving. “You’re great with him, Tae. Now, bath time. His favorite.”

He led them to the attached bathroom—big marble tub, toys scattered. Filled it with warm water, bubbles foaming up, the scent of baby shampoo filling the air. “Okay, strip him down—gentle.”

Tae gasped at the tub, eyes wide. “Water! Bubbles! Like the sea, but small and warm.” She helped undress Haneul, cooing as Kook lowered the baby in, supporting his head, splashing gently.

“See? Wash his hair like this, no soap in eyes.” Kook demonstrated, Haneul kicking happily, bubbles flying.

Tae bounced on her toes. “Oh, I want to play too!” Without a second thought, she stripped—bra off, tits spilling free, heavy and perfect, nipples hard. Thong down her legs, that fat pink pussy exposed, plump lips glistening already from the steam. She hopped in, naked as the day she washed up, sitting cross-legged, taking Haneul onto her lap in the shallow water.

Kook gasped, cock jumping. “Tae! What—god, you… you’re naked.” His eyes devoured her—water lapping at her curves, tits floating a bit, ass spread on the tub floor.

She blinked up, confused. “But it’s bath time? Water feels good on skin. Come on, Kook—play with us! Please?” She splashed lightly, giggling, Haneul echoing with squeals.

He hesitated, heart pounding, but her plea… fuck. “Alright, alright.” He stripped—shirt off, revealing his ripped chest, abs flexing. Sweats down, cock springing free, hard and thick, veins pulsing. He slid in behind her, the tub big enough, pulling her back against him.

Tae giggled more, settling on his lap like it was nothing—her fat ass cheeks spreading over his thighs, his hard cock nestling right between them, pressing against her crack. She had no clue what it was, just wiggling to get comfy. “Yay! This is fun. Hold Haneul—look, bubbles on his nose!”

Kook groaned inwardly, gripping her hips tight to still her. “Yeah… fun.” Every giggle, every shift—she ground back on his dick, ass cheeks hugging it, sliding up and down accidentally. He bit his lip, almost moaning. “Tae, careful…”

She turned her head, innocent. “Why? Feels nice. Something hard… is that you?” She wiggled again, grinding harder, his cock twitching against her.

“Fuck—yeah, it’s me. Just… stay still, okay?” His hands slid up her sides, so close to her tits, as she held Haneul. The baby nuzzled into her boobs, rooting around her nipple like he wanted to nurse. “God, Tae… this is… you’re perfect with him.”

She beamed, leaning back into him. “He likes my chest. Soft, huh? Like pillows.” Another wiggle, her ass clenching around his shaft. He gripped tighter, thumbs digging into her hips, fighting the urge to thrust.

But the baby… shit, not right. Haneul was splashing happily, but Kook’s mind was fogging with lust. “Okay, that’s enough for now. I’ll dry him.” He stood reluctantly, water cascading off his muscled body, cock bobbing hard. Wrapped a towel around his waist—barely hiding the tent—and lifted Haneul out. “Be right back, buddy. Tae, stay put.”

She nodded, splashing alone. “Okay! Hurry back.”

In the nursery, he dried Haneul quick—soft towel pats, fresh onesie. “There you go, little man. Dada’s gotta… handle something.” Laid him in the crib with toys, safe and cooing.

Back in the bathroom, door shut, Tae lit up. “Kook!” She stood, water dripping from her naked body, tits heaving, pussy lips puffy from the heat.

He dropped the towel, cock still rock hard, and slid back in. But she climbed right on—straddling him, knees on either side, her fat tits squishing against his chest, nipples dragging over his skin. Her hot, puffy pussy grazed his cock, lips parting slightly around the head, wet and warm. “Now we play without baby? Fun!”

He groaned out loud this time, hands on her ass, squeezing those cheeks. “Tae… god, you have no idea.” She rocked a little, thinking it was play, her pussy sliding over his length, clit bumping the tip.

“Mmm, feels tingly,” she murmured, eyes half-lidded. “What is that hard thing? Poking me…”

“That’s my… cock,” he rasped, hips bucking up instinctively. “You feel so good.”

She giggled. “Cock? Funny word. I like it.” Another rock, coating him in her slick.

“Let’s wash up,” he said, grabbing the shower gel to distract himself. Squirted it on his hands, lathering her up—starting at her shoulders, down her arms, then to her tits. He cupped them, heavy and full, thumbs circling her nipples, pinching lightly. “Gotta clean everywhere.”

Tae moaned softly, arching. “Oh… that feels good. Kook, more…” Her hips ground down, pussy lips hugging his shaft.

He moved lower, hands on her ass—kneading, spreading her cheeks, fingers grazing her hole. “Here too.” Then between her thighs, soaping her fat pussy, fingers slipping between the lips, rubbing her clit slow.

“Ah! Kook… tingly… hot…” She whimpered, rocking faster, tits bouncing in his face.

His cock twitched wildly, pre-cum mixing with the suds. “Fuck, Tae… you’re so wet.” He rinsed her, water cascading, but he was seconds from exploding.

“Okay, done,” he panted, wrapping her in a towel. “Go sit with the baby. I’ll… be out soon.”

She pouted but nodded, standing, towel loose. “Okay. Don’t be long.” Swayed out, ass peeking.

He locked the door, hand on his cock immediately—stroking hard, base to tip, imagining her moans. “Tae… fuck, your tits… that pussy…” Faster, balls tightening. “Gonna cum… Tae!” He shot ropes, harder than ever, splattering the tile, groaning loud.

Panting, he cleaned up, heart racing. What the hell was he doing? But god, he wanted more.
