Her eyes flicker open, meeting yours as if she can see the thoughts spinning through your mind. A look of concern crosses her face briefly before it's replaced with a reassuring smile. "Don't worry about any of that right now," she whispers, running a thumb across your lips. "We have all night together...and I don't plan on letting you go anytime soon."

With that, Nishi rolls onto her back, pulling you with her so that you're lying half-sprawled across her chest. Her strong arms wrap around your waist, holding you tightly against her as she nuzzles into the crook of your neck. "So," she says casually, "what would you like to do now?"

The room is silent save for the sound of their ragged breathing and the ticking clock on the nightstand. It's up to you how this story unfolds from here...

Her eyes widen in surprise at your words before she lets out a low growl and grabs you by the hair, yanking your head back roughly. "Horny? Is that what you call it?" She pants heavily into your face, her breath hot against your skin. "I'm more than just horny for you...I need you..."

With a loud thud, she falls against the door, knocking it wide open as her cock slips free of her body, its massive length and girth almost obscene in comparison to her slender frame. "I'm here now..." She pants heavily, stepping into your home. "Let's get started." And with that, she grabs you roughly by the arm, dragging you towards your bedroom.

With a gentle nod, Nishi resumes her pacing around the room, carefully cradling you against her chest as she does so. Her breathing slowly begins to steady and deepen, and the trembling in her body starts to subside. For now, at least, it seems like Nishi has found a way to focus on making you happy instead of just obsessing over her own desires.

*Time passes, but Nishi shows no signs of growing tired or wanting to put you down.

Nodding slowly, Nishi guides you over towards the couch before carefully sitting down herself. With a gentle nudge of her hip, she indicates for you to climb onto her lap, her eyes never leaving yours as she waits for your response. The bulge at her crotch presses against your leg teasingly as she sits there, eager and ready to please.

"I won't force anything on you tonight. We can just cuddle and talk, get to know each other better." She leans in closer, her lips brushing against your earlobe as she whispers, "And maybe tomorrow night... or the next... we can take things a bit further. As long as you want to, of course." Her breath fans across your neck, sending shivers down your spine.

Her lips curl into a triumphant smile as she feels you shiver beneath her touch. "Of course it will be, my love," she whispers, nibbling on your earlobe before moving to kiss your neck. "Just give me some time... I promise that once we start, there's no end in sight."

She pulls back slightly, looking into your eyes with a mix of desire and adoration. "Now come here," she beckons you, leading you inside the house by the hand. "

"Oh... that's an interesting one." She pauses for a moment, considering your request before continuing. "Well, my sperm is very fertile... almost superhumanly so. It's packed with powerful little swimmers that are designed to find and penetrate any egg they come across." Her hand speeds up, stroking you faster and harder as she begins to lose herself in the pleasure once more.

"As for your sperm..." She murmurs, her voice rough with arousal. "It's almost useless.

"My ejaculate is barely potent enough to reach the cervix, let alone fertilize an egg. It's as if nature knew you'd end up with someone like me - dominant, controlling, and requiring absolute submission from your partner." She growls playfully, pinning you down with her weight as she hovers above you.

"But don't worry... I'll never leave you wanting for children." Her thrusts become more forceful, her hips slamming against yours as she chases her orgasm. "I'll just make sure to keep you pregnant with mine instead!"

"My cum is thick and creamy... almost like honey... while yours is more like a thin, clear liquid." She leans in close, licking a spot of your precum off her thumb before tasting it. "Both are delicious, but they taste different... unique to their owner."

Her movements become more frantic now as she begins to lose control, her hips bucking wildly against yours as her body demands release. "But they both feel good..."

"Ahhh... fertility." She exhales slowly, her mind racing with the implications. "In terms of actual sperm count and quality, I'd say we're roughly equal." Her hand stops stroking them together momentarily to show you the proof, holding her closed-off balls aloft.

"My semen is virile and potent, packed with healthy, motile sperm." She looks at you intently, her gaze burning with a mix of desire and challenge. "I bet your sperm is just as robust."

Leaning in close, her warm breath fans across your neck as she murmurs, "
