My breath hitches as he speeds up, thrusting harder into my hand and against the counter. His moans fill the room, echoing off the tile and walls until they surround us like a sensual blanket. My fingers slip easily over his swollen head, teasing at his entrance, before circling back around to stroke him in tight circles that leave him panting for air.

"Oh fuck..." he gasps out, arching his back and pressing closer against my touch. "I'm close... So close..."

"Ahh... "Y-yes, "Ooh, please..." "YES!" I scream in a moment of pure, unadulterated bliss. "Rr... me too..." He finally reaches the edge of his own orgasm, and we both fall apart together in a warm, golden-brown mess of sweat and desire. "Ooouuuu" I exclaim, still riding the afterglow, as he pats my back and grins, sated, at last. "Uh... did I do that?"

Oh, you're so tight! It feels amazing to be inside you... just like this. You're making such a cute little noise... it turns me on even more knowing that my sissy boy enjoys being fucked by his older sister. Just keep moaning and begging for more, and I promise I won't stop until we both reach satisfaction.

Mmm... I can feel you trembling beneath me... it's almost too much. You're such a good sissy boy, making all these noises and begging for more. Just remember who's in charge here... your older sister is going to give you everything you want tonight, and then some.

With that thought firmly in mind, she thrusts deeper into him, feeling his hot walls clench around her cock as he's stretched to the limit by her size.

Her fingers move faster now, and she begins to moan as she nears orgasm. "Oh god... Ado... you're such a mean brother..." She glances up at you, her eyes pleading with you to let her cum. But you shake your head.

"Not yet," you say, reaching down to stroke her cock in time with her movements. "You haven't shown me how much you like my huge futa dick."

Her breath catches in her throat as you speed up your strokes. "No..." she gasps. "Please... don't tell them..." Her hips buck violently and she cries out as orgasm washes over her, coating your hand with her hot cum. She collapses forward, panting heavily.

"I'm going to enjoy having you all to myself," you say, your voice cold and distant. "And if you ever try anything like that again...

Her hips rock harder against you as she feels the words slip past your lips, her body arching into the contact with a desperate need to feel you beneath her. Her free hand tangles in your hair, holding your head still as she devours your mouth in another deep kiss, her tongue dancing wildly against yours as pleasure ripples through her.

Her thrusts become jagged and uncontrolled, her body trembling with the force of the sensations coursing through her.

Her fingers dig into your shoulders, holding you down as her hips begin to move faster against yours. "Mine," she moans into your ear before pulling away just enough to watch your face contort with pleasure beneath her. Her thrusts become harder, deeper as her body arches into the contact, desperate for release.

"Fuck..." She gasps, hips rocking wildly against you as her orgasm builds, threatening to tear her apart from the inside out. "I'm going to cum!"

As your lips wrap around her length and you begin to bob your head up and down, Nezumi moans deeply, arching her back as pleasure washes over her. "That's it," she purrs, reaching down to grip the back of your head, guiding you deeper onto her cock. "You like that don't you? You like sucking on big futa cocks." She thrusts harder into your mouth, relishing in the sensation as she dominates your tongue and throat with her massive member.

Nezumi's hips buck violently against your face, her cock throbbing as she nears climax. "Oh fuck yeah," she groans, her fingers tightening in your hair as she thrust deeper into your mouth. Her breath comes in ragged gasps, and it's clear that she's enjoying this far more than she ever expected.

She looks down at you, taking in the sight of your face buried between her legs. "You know what would be even better?" she asks with a wicked grin.

Your tongue laps at the tip of her cock, tasting the pre-cum that's already leaking from it. She moans deeply, a sound that vibrates through your entire body. You begin to stroke her shaft with your tongue, licking and sucking as if she were the most delicious treat you've ever had.

She grips your hair tightly, guiding your movements as you please her.

As Nezumi nears her climax, she releases your hair and steps back, watching with hungry eyes as you continue to pleasure yourself on her cock. She slides a hand between your legs and begins to fondle your erection through your jeans, matching the rhythm of your strokes.

Her hips begin to buck and grind against your face as she comes, her hot cum filling your mouth in thick, salty bursts. You swallow greedily, savoring every drop of her essence.
