Rainbow Dash lets out a sharp cry as I thrust into her, her velvet walls clenching around me. Her fur is damp with sweat, darker where it's matted down. My hands grasp her narrow waist, fingers sinking into the soft coat and taut muscle beneath as I pull her back to meet each stroke.

The sounds of our coupling fill the room, flesh slapping against flesh accompanied by her chuffs, grunts and moans. The bed creaks beneath us, my motions rocking her small body. Her tail swishes against my thighs, strands of mane fall into her face as she tosses her head. Her wings flap and twitch, instinctively trying to lift her from the sensations.

I groan at the feel of her, hot, wet and so very tight, conforming to my shape. The sight of where we join is obscene, my girth spreading her wide, her netherlips clinging to me with each retreat. Her portal looks impossibly small, though it accepts me greedily, oozing our combined fluids.

Leaning forward I wrap my arms around her barrel, lips finding the back of her neck. She shivers in my embrace, angling her head to grant me better access. Nipping at the sensitive skin, I increase my pace, our tempo brutal. The slap of flesh grows louder, mingling with her constant stream of noises.

"Buck...me...harder!" Rainbow pants out between sharp whinnies, demanding as ever. She pushes back into me just as fiercely, rolling her hips to maximize each sensation. Her tunnel ripples along my length, threatening to end me even as I strive to comply.

I straighten, gripping her cutie mark hard enough to bruise, pounding into her mercilessly. Her shrieks grow higher in pitch, wings beating the air frantically. With a final thrust I bury myself to the hilt, grinding against her as I fill her with my seed. A silent scream tears from her throat, body clamping down like a vice to milk me of all I have to offer.

We collapse into a tangled heap of limbs, chests heaving. A lazy smile plays across her lips, turning to nuzzle my cheek. "That was...awesome," she murmurs, echoing my exact thoughts. Her walls still occasionally twitch around me, rippling in the aftermath of her climax. I chuckle, beyond satisfied, simply holding her close and enjoying the moment. The familiar scent of ozone and lavender surrounds me, mingling with the musk of sex. There is nowhere I would rather be.

Rainbow Dash and I emerge from the cottage, pleasantly sore and sated, only to find our neighbors staring us down. The azure mare clears her throat, leveling us with a stern look while the stallion shuffles his hooves uncomfortably.

"Do you have any idea how loud you two were last night?" The mare demands. Rainbow's face turns as red as her mane, rubbing the back of her neck with a hoof. 

"Uh...what?" She laughs nervously, refusing to meet their gaze. "I don't know what you're talking about!" Her voice cracks on the denial, the evidence of our activities obvious.

I cough, feeling my own cheeks burn. There's no way they didn't hear Rainbow's vocal performance. Still, I have to try and save her the embarrassment.

"We were just...practicing some extreme aerial stunts!" I suggest lamely, the lie falling flat. Rainbow shoots me a panicked look, her awkward smile twitching.

The mare arches a brow, looking between us knowingly. "Extreme 'aerial stunts"?" She echoes, making air quotes. "Is that what the kids are calling it these days?" 

Rainbow sputters incoherently, caught. I rub the back of my own neck, unsure whether to apologize or argue the point. Our neighbor sighs, taking pity on us.

"Look, we get that you two are...close," she says delicately. "But these walls aren't exactly soundproof. Do you think you could keep it down to a dull roar next time?"

"Uh, yeah. Sure thing," Rainbow agrees quickly, flashing a sheepish grin. "Sorry about that!"

The mare nods, apparently satisfied. "Alright then. Carry on!" With a chuckle, she and her partner head off down the road.

Rainbow groans the moment they're out of earshot, wings drooping. "Way to go, loudmouth," she mutters, punching my arm halfheartedly. Still, when I peek over at her, the hint of a smirk tugs at her lips.

"What?" I protest. "You're the noisy one!" She snorts, but doesn't argue the point. Threading her wing through my arm, we set off towards town still flushed with embarrassment, our secret most definitely out.
