Koo slipped back into the big apartment before Suho’s car could pull up in the driveway. Her heart was still racing, her thighs sticky with Tae’s cum, but this time she didn’t feel guilt or fear. Instead, she felt light, glowing almost, like she’d been reborn.

She had him again.

Tae.

Her Tae.

Before leaving his little house, they had exchanged numbers, his rough hand brushing hers as he saved her contact. He hadn’t said much, but the way his thumb stroked her knuckles told her everything—he wasn’t going to let her go again.

She stripped quickly, showered away the traces of their lovemaking, and slipped into a soft dress that Suho liked seeing her in. She was just brushing her hair when she heard the front door click.

“Koo?” Suho’s voice echoed.

“Yes, I’m here,” she called sweetly, walking into the living room with a calm smile.

He looked tired, his tie loosened, his glasses slightly askew. But what startled her was his face—it wasn’t angry tonight, but apologetic.

He stepped forward and cupped her cheek, his thumb brushing over the faint mark from yesterday. “I… I’m sorry about last night.”

Koo blinked, forcing herself to look surprised, then softened her expression. “It’s alright, Suho… you were upset. I shouldn’t have gone against your preference.”

Inside, she felt nothing—his apology meant nothing. He didn’t matter anymore. Tae did.

Suho sighed in relief, pulling her into a stiff hug. “Thank you for understanding. You’re a good fiancée, Koo. You make this home warm for me.”

She smiled into his chest, pretending to melt, when in truth her heart wasn’t here at all.

Later that evening, after serving him dinner and listening to him ramble about numbers and files, she retreated to her bedroom. Suho stayed in his study, working late on his laptop, leaving her the perfect space.

She slipped under the covers, phone in hand, and saw the first message from Tae.

Tae: Did you get home safe, baby?

Her heart skipped. She typed quickly.

Koo: Yes… I’m home. I already miss you, Tae.

The typing bubble appeared almost instantly.

Tae: I miss you too. My bed smells like you. My cock is still hard thinking about your fat pussy around me.

She bit her lip, her thighs pressing together as wetness pooled between them.

Koo: Stop… you’ll make me wet again. Suho’s in the other room.

Tae: Good. Let him hear you moan for me. I don’t care. You’re my slut, Koo.

Her breath caught. She typed with trembling fingers.

Koo: Yes… your slut. Always yours.

She rolled on her back, staring at the ceiling, a stupid smile on her lips. Her fiancé was just a few doors away, but her entire being was wrapped up in Tae—his words, his touch, his hunger for her.

Suho returned later, kissing her forehead before slipping into bed. He never noticed the way she clutched her phone to her chest, the way her heart raced for another man.

That night, Koo drifted off to sleep with a smile, not because of her fiancé’s apology, but because of the promise Tae had whispered before she left his house:

“I’ll come to you every time I can, baby. You’ll never be without me again.”
