The moment Spike’s thick head passed her pussy lips, Rarity felt her entire body tense, contracting like a spring as his girth spread her wide. An instant later, she gasped, and felt the spring of her muscles loosen, every part of her flexing as the pressure was released. Her inner walls contracted, and her stallionhood flexed, arching impressively as a thick rope of cum splattered across the floor below her.

“Geeze, Rarity.” She panted, groaning, as Spike’s sheepish voice rang in her ears. “I barely even put it in.”

Rarity shifted her hindquarters, a squeak of pleasure and need slipping past her lips. “Which means you’re late, Spikey dear,” she said, squirming to best feel his ridged head inside of her. She felt him grinding against her soft, slippery insides and squealed, another orgasm rocking her body. A second rope of cum splattered over the puddles of the first, thick and creamy and infused with lust. “A-all the way, if you please.”

She didn’t hear him so much as feel him. A set of claws wrapped around her middle and pulled her backward. Rarity squealed, her ass pushing backward and up as she welcomed her lover’s length inside. Each fresh inch set her body spasming anew, her cock throbbing along with the contractions of her dripping cunny.

When Spike took her in earnest...now that sent her spiralling into a heaven of pleasure. She heard his grunts and echoed them with groans and grunts of her own, soft, ladylike moans mixing with his deep, masculine voice. Each time he rammed his length inside of her, she came again. She hardly knew or understood why; all she knew was that each pump of his hips sent her peaking to a climax, femcum squirting from her cunt even as her jizz covered the floor.

Ooh, but she was so messy. The puddle beneath her was spreading, and her thighs were dripping with her flower’s juices. Rarity moaned, practically begging for more as Spike rammed his length inside of her again and again. “Take me, Spike,” she groaned, sweat slipping down her forehead. “Make me your mare!”

Had she glanced back, she knew what she would have seen: his eyes, narrowed to lizardlike slits, and his pupils dilated with desire. She felt his heavy balls slapping up against her ass with each thrust, and moaned and whinnied for more. Oh, how she longed for him to empty his seed inside of her - to fill her with his load. The very thought of it sent her spiraling down into even dirtier thoughts, and Rarity cried out with pleasure as she orgasmed again.

Her climax seemed never ending - a constant rollercoaster ride of peaks that never quite seemed to turn into valleys. Her body flexed and spasmed and clenched, each contraction of her marehood echoing the throb of her cock. Femcum splashed around his feet and her hooves, her feminine juices running down to mat her thighs as her marehood convulsed with pleasure for the dozenth time. Rarity felt her breath leaving her chest; her mind was awash with a constant stream of satisfaction and ever-heightening summits of pleasure. More and more of her cum splattered in fat globs on the ground below her, put out by an oversized stallionhood just barely smaller than Spike’s own.

Each pump of his hips splashed her flank and rump with her own juices, the schlick-schlick of his massive member between her folds sending her trembling with warm, overbearing fullness. Behind her, she could almost see Spike’s eyes following her bouncing, jiggling rump, her round, spankable cheeks covered with his pre mixing with her femcum and sweat.

“Y-you’re so big,” Rarity moaned, just as her cock squirted out another heavy load of jizz. The floor beneath her stank of sex and jizz, and the next slap of Spike’s grapefruit-sized nuts against her ass spurred an even larger orgasm from her footlong member.

She moaned as Spike’s claws tightened around her juicy rear, and shuddered when she felt his long tongue flickering against her ear. “Think I’m big?” Spike rumbled, his voice sending shivers through her body. “That’s nothing compared to how big I’m gonna leave you, Rarity.”

The gentle stroke of his hand against her underbelly left her trembling with a need for more - and she got it. The next outstroke of his cock sent her orgasming again, her body shaking with the aftershocks of what felt like a lifetime of climax. Rarity squealed, cumming again and again as visions of a future, pregnant self filled her mind. She could see it so easily, her belly big and round and squirming with new life, her erect cock pressed against her gut as Spike fucked her senseless even then -

Without even missing a beat, Spike flipped her over onto her back, both hands firmly grasping her hind legs. Rarity’s shrieks and groans filled the air as they began to fuck like animals in earnest, his flesh smacking against hers as she came again and again. It was a never ending orgasm, a climax of perfect sex and sensuality that left her cock shuddering and dripping with jizz while her weighty balls churned up ever-larger loads.

And there was so much of it. She almost hesitated to see how much Spike would orgasm; she’d long since lost count of her own climaxes, and her balls were an entire inch smaller than his in radius. She couldn’t help it, though; he was so big inside of her, the very touch of his body to hers so sensual, so intimate, that each brush of his scales against her fur was like a thunderstorm going off in her cunt.

Rarity kept cumming, her screams reverberating against the walls as Spike’s bestial grunts filled her ears. Her cock kept throbbing, spasming as she coated herself in her own seed, thick white stripes of spunk layering across her white belly and chest as she squirmed and swayed. Below her, the massive puddle she’d left from her earlier orgasms squished and stuck to her fur, a pool of hot, creamy liquid matting her coat with the stink of sex. Rarity moaned as her hips bucked in time with Spike’s thrust, a fresh load of her own seed spattering her face and cheeks.

Her balls felt endless, as full as the ocean; her cunt continued to contract, a fresh climax striking her each time Spike struck against her g-spot. She could hear him grunting, panting, as her constant flexing and contractions teased him, pleasured him, stroked his immense length closer and closer to the finish line. The feeling of him inside of her was indescribable; she could barely even think. She was so covered with her own jizz, nearly a full gallon of her own fluids covering her body and leaving her fur musky and sticky. Rarity moaned, a hoof going to her belly as she felt it sloshing with Spike’s precum. There was just so much -

And there was about to be more.

Spike grunted, his voice so loud and deep that it was nearly a roar, and bottomed out inside of her. Rarity gasped, moaned, shrieked as his orgasm finally went off, exploding like a volcano inside of her. She rode it out with a climax of her own, moaning as her cock shot thick ropes of jizz all over her face and chest. Her muzzle fell open, and she felt fat gobs of her own spunk cover her tongue and throat. She gulped it down as quickly as she dared, letting what felt like pints of her own load rush down to her stomach even as Spike filled her up with his own seed. She rubbed her belly, feeling it swell as his mighty organ swelled and throbbed inside of her, filling her very womb with his load as her gut bloated and sloshed.

Her back arched, a final climax hitting her. A stream of jizz splurted from her cock and arched up in the air over her, hitting her right over the face and covering it in a mask of white. Rarity gasped, moaned, and then relaxed, her body hitting the ground with a thump. Above her, she could hear Spike heaving, inhaling desperately.

She groaned softly, then lifted a hoof to wipe away the spunk covering her face. She burped, her own jizz dribbling down her muzzle as she continued to massage her cum-bloated belly. Spike looked down at her with bright red cheeks and a wide grin, his cute, dragonish face both satisfied and sheepish.

“Wow,” he said. “You really enjoyed that.”

Rarity licked her lips, tasted her cum. She ran both hooves down her chest, feeling the matted, cummy fur and shivered. She was absolutely drenched, sticky and coated in the stuff. “Yes,” she murmured, shivering happily, her member slowly softening. Her balls felt finally, mercifully empty. “I certainly did.”
