You go meet Miho

The heavy wooden door of Miho’s quarter slid shut, sealing the two of you away from the rest of the brothel. The room was softly lit by the warm glow of a paper lantern, casting long, intimate shadows across the tatami mats.

Miho turned to you, pouring a small cup of tea. "When Inoue-san told me you're coming back after last night, I'm surprised. I was about to return home."

"You have a house?"

"Well, yes. This is my place of work, with a bed included."

"Oh," you reply in embarrassment.

"So, Doe-sama, what brings you here so early? I thought even with our session yesterday, you would only come tomorrow."

If you do, you would have missed meeting her. ​"I talked to my grandfather."

She smirked. "And?"

My grandfather has a birthday coming up soon," you said, surprising her.

She probably expected your grandfather to object to your fucking her. ​Miho quickly schooled her expression, offering a gentle nod of congratulations. "Ah, is that so? Please extend my warmest wishes to him. But tell me... what kind of present does a man of his standing want?"

​"A birthday present," you answered plainly.

​Miho blinked, her brows furrowing slightly in confusion at the overly general reply. "A birthday present? Well, yes, but what sort? Fine silk? Rare tea? A piece of antique calligraphy?"

​"I think he would like a Koi," you elaborated.

​"A Koi?" Miho repeated, tilting her head.

​"A Koi no ko," you clarified softly.

​The breath hitched in her throat. The double meaning hung in the air, shifting from the traditional carp fish to the literal phrasing of a child of love. The subtle insinuation landed instantly, and a hot, deep crimson flushed across Miho’s cheeks. She pressed a hand to her chest, her lips parting as the realization settled. The "birthday" you were speaking of was not merely the passing of another year for your grandfather, but the one that will involve her in bringing a new life into the family fold.

​"Really?" she whispered, her voice trembling slightly with a mix of shock and sudden, heavy emotion. "You... you are serious?"

​"You did say so when we did it," you said calmly, stepping closer. "Only if you want to."

​Her blush deepened, spilling down her neck as her heart pounded against her ribs. She looked up at you, her eyes dark with a mixture of arousal and desire. "But that was to increase our... Intense pleasure."

"Yes, but the idea took hold," you say, making the insinuation on purpose. "Don't you feel the idea enthralling, even right now?"

​"Yes," she breathed, her voice barely above a murmur. "Let's work on it." she say as she leads you to the adjoining bedroom.
