“Twilight? Are you okay?”

                    Twilight opened her eyes groggily. It felt as though she had hadn’t slept properly in years. She shut her eyes to block out the burning light as soon as it touched them, and felt one of her hooves around her body. Soft. So, not the floor again. Where had she been last night? She remembered the moon, and a delicious taste… She inhaled deeply, and the fragrance of another mare on her snout caused her eyes to snap wide open.

                    “Twilight?” the voice repeated, concerned. Twilight turned her head to the right to find an orange cushion underneath. Exhaling with the effort of moving through her exhaustion, she tilted her head to the left to find a face staring back at her, a white coat and shaggy brown mane.

                    “Are you okay?” Lucky asked again, his brow furrowed with apparent distress. “I found you outside when I went to get the paper, and you looked like you’d been rung through the washer. I’m glad you’re awake, at least.” The colt hazarded a small smile, but his face returned to concern almost immediately. “Do you want me to go get someone? If you’re hurt, or need to see a doctor…?”

                    She wanted to kiss him again. That first kiss was heaven, and she knew he’d have a delicious cock, much bigger than the one she’d had last night. She wanted to taste it, and bounce her body on top until she sprayed girlcum all over his perfect alabaster fur-

                    “Unh, no, please!” Twilight shouted, throwing herself from the softness underneath her onto the hard floor with a thump. The orange couch cushion rolled off with her, landing on top of her head. Twilight buried her face in her hooves, planting her nose firmly onto the ground and muttering to herself. “No no no no no no no no no no no no no no no…” she said over and over again, like a mantra.

                    “Twilight!” Lucky dashed to the fallen unicorn’s side, pressing one of his hooves into her side, half as reassurance, and half to check for any real damage – not from the fall, but from whatever ordeal Twilight might have been through the night before. “Listen, if you need me to get a doctor, I can go, I’ll be right back-“

                    “Book!” shouted Twilight, arching her body as far away from Lucky as possible, though her collapsed position made any real distance difficult. “Need to… read book, has… says what happened… need to fix… can’t think, properly…” Twilight was babbling, struggling to bring herself upright, her legs giving out with each attempt and sending her back to the floor. Lucky shouted, and knelt down next to her, placing one of his hooves on either of his shoulders.

                    “Hey hey hey! Calm down, it’s okay, take a second and breathe. It’s alright, you’re safe here. Tell me what happened and I’ll help make everything better, okay?”

                    His voice was so sweet. He wanted to help her. He wanted her, Twilight told herself. She wanted him too, more than anything. Oh Celestia how she wanted him. There was a nagging though in the back of her head, stabbing at her impulses they arose in an attempt to drive them back. She had to get back home, to show him, show anyone her journal. Maybe she could still fix it, she could still think about something other than riding his big, hard dick, letting it fill her up over and over until Lucky spurted his cum all over her face, and she bathed in it, licking up every drop and then doing it again, fucking him all night-

                    “Ahhhh!” Twilight screamed, throwing herself toward the nearby door. The shifting of her legs pulled the throw rug her back half had been laying on, and Lucky’s footing faltered slightly, sending him forward as well, landing atop Twilight’s sprawled out body. He let out a small ‘oof’ as the wind was pushed from his lungs, but he quickly recovered, propping himself up and lowering his face to meet Twilight’s. He was very worried now.

                    “Twilight, listen to me, it’s okay, please. I don’t know what happened, but I can help, really. I just need you to calm down-“

                    Twilight kissed him, swallowing his words, and then his tongue as she pressed her face into his furiously, already moaning from the touch of Lucky’s soft but masculine lips against her own. Lucky’s eyes widened in shock, and he tried to pull himself back, but Twilight’s forelegs wrapped around his neck, locking him in place with the strength of her desire. She kissed him harder,  slobbering into his mouth unabashedly, her saliva trickling out of her mouth and onto Lucky’s snout. The colt tried harder to draw himself away, but Twilight’s pursuit was insistent, raising her body up and reversing Lucky’s momentum, turning his attempt at escape to her advantage as she used the force of Lucky’s motion to push him to the floor, upon which she threw herself on top of him, finally breaking the kiss.

                    “Twilight, what are you doing? Stop!” Lucky struggled to pull himself back, but Twilight’s grasp was firm, and she shoved Lucky onto the floor completely, pinning his forelegs with her own and eyeing his body hungrily.

                    “Please… need you… need to fuck… fuck me. Want you, so bad…” Twilight mumbled deliriously. She was grinding her flank on Lucky’s crotch, and her body shivered as she felt his cock rising involuntarily in response to her warmth and wetness pressed against him. There was a pain at the back of Twilight’s mind again, like a pin prick amidst a soft cushion, trying to urge her away, remind her of something, but being buried in an avalanche of need and want. Everything she wanted was right her, she was on top of it, inches away from being inside her.

                    Lucky gave up on words, struggling to pull himself back and throw Twilight off his body in the same motion. But as he propped himself up on his hind legs, the throw rug again slid with the adjustment of his weight, sending him back to the ground. On the way down, his head collided with the small side table next to the couch, sending the lamp in the center off the opposite side of the surface and onto the ground. The length of the descent to collision was relatively short, but it was enough to jar him from his sense for a moment, and Twilight took that moment to strike. She wasted no time, raising herself up from Lucky’s body and grasping his half-hard cock in her hooves, stroking it up and down several times in preparation.

                    “Yessss,” she drooled, tongue hanging half-way out from her mouth as Lucky’s size grew. Every piece of his mind’s presence knew the unicorn preparing to straddle him was delirious, obviously not in her right mind, and the proper thing to do was to resist her advances and get her the help she very clearly needed – but his body’s reaction was involuntary, and he could feel his head spinning from its collision with the coffee table. He tried to scramble upward again, but his hoof faltered, sending him flat onto his back as Twilight continued to rub his cock hungrily. He was almost at full size now, and Twilight’s earlier estimation proved correct – Lucky was an exemplary stallion, in both length and girth. Twilight licked her lips as the member between her hooves grew. She could feel her wetness leaking down her legs and onto the head of Lucky’s cock beneath her. No more waiting. Now, she needed it now, needed it more than anything, she’d die without it-

                    “Aaah!” Twilight squealed as she lowered herself onto Lucky’s stiffness. For the first time since she’d taken someone’s cock, Twilight felt herself struggling with the size. Her pussy was eager to accommodate the colt’s full length, but as she pressed her body down, she could feel her inner walls stretching. Despite his relatively modest frame and stature, Lucky’s package was mammoth in size. It was perfect.

                    “Unnngh, yes, good, so good, more, need it, more,” Twilight babbled, sinking herself onto Lucky’s erection, now coated in the copious deluge of fluid flowing from Twilight’s cunt. She paused three quarters of the way down, her face clenched in concentration as she struggled to fit the rest of the colt’s sizable girth inside. Slowly, in fractions of an inch, she could feel Lucky’s dick slipping into her, until finally she felt his head pressing against something, an inner wall that meant he had bottomed out. Twilight looked down to her pussy to find at least half an inch of Lucky’s cock still outside. The sight made her eyes roll back in her head, and she shuddered. Every time had been better than the last, and her mind was beginning to fail at it attempts to compare the sensation. If the night before had been earth-shattering, the feeling coursing through her body was the end of existence, and she had ascended to another plane of being, full and complete with Lucky’s gargantuan girth filling her to her limits. She shifted her hips in an attempt to readjust and begin riding Lucky’s cock the same way she had dreamed, but in doing so pressed her clit against the colt’s skin. The tiniest contact was enough to push her over the edge, and for the first time before she was finished, Twilight came intensely, soaking Lucky’s beautiful white coat with her arousal. She buried her face in his chest, screaming into his fur as her hindquarters twitched on the stallion’s dick.

                    Lucky was in a daze. Twilight, the pleasant librarian he’d taken misdelivered letters to several days ago, was riding on his cock, and cumming furiously besides. He knew he should stop her, that she wasn’t in her right state of mind, but the clenching on his dick felt unbelievable. Twilight’s spasms made his cock twitch inside her, and the response only seemed to spur on Twilight’s orgasm, sending her into convulsions as she rode out the end of her climax. Finally, panting, Twilight lifted her head from Lucky’s chest, looking at the colt with her eyes have open. Her irises looked glazed, as though she was on some kind of diabolical drug, and Lucky almost managed to open his mouth to protest before Twilight lifted herself up for a moment before slamming her flank back down, taking his whole length in one smooth motion. Lucky couldn’t help but groan as he bottomed out, the bottom of his shaft just peeking out from Twilight’s leaking cunt.

                    Twilight continued her up and down motion, tapering the sudden and ferocious thrusts to a more sultry motion, grinding her side to side with each motion. She leaned forward with her mouth next to Lucky’s ear as she did so, pressing her mound against the base of Lucky’s shaft and arching her body against his stomach for several seconds as she continued grinding.

                    “Do you… like fucking me? You feel so good, so good, you made me cum so hard,” Twilight murmured seductively, giving a nibble on Lucky’s earlobe as she spoke, all the while grinding herself while Lucky filled her up completely. Lucky struggled to protest, but the impulses overwhelming his body were becoming too much to struggle against, especially when combined with the light-head feeling left over from his collision with the table. Instead, he kept silent, groaning involuntarily as Twilight pressed her clit against his stomach and gyrated her hips wildly. The extra pleasure was noticeable, and Twilight bit Lucky’s ear hard as she moaned loudly, shutting her eyes as her body surged with ecstasy.

                    “Oh, fuck,” she mumbled, still grinding herself back and forth on the whole of Lucky’s shaft. “Please, I need you… tell me how good it feels, to have me… on top of you, grinding on top of you like this.” Twilight’s only coherence now seemed to be in the throes of her sultry whisperings, assembling syllables solely for the purpose of encouraging her partner. She didn’t just want to talk dirty to him, her body needed it.  Every word made the heat coursing through her body burn a little hotter, every filthy sentence caused her to arch her back with pleasure. It was bliss on top of bliss, if only he would say the same things to her.

                    A light bulb seemed to go off in Twilight’s head in that moment, a combination of the sudden headache dissipating all at once and the ever-waking sensation that had followed. It was as though a key had turned, unlocking a door that had been bursting at the hinges until that moment, sending a cascade of understanding through her mind.

                    What had the pegasus called her the other night?

                    “Let’s leave this crazy slut…”

                    That was what she wanted.

                    She was a slut, and she’d never felt happier.

                    “Tell me,” she drawled in Lucky’s ear as she rode him, revelling in the sensation of his cock twitching inside her.  “Tell me how good it feels.” She could tell he was enjoying it now, as much as he might have struggled. She wanted to make him cum, for him to fill her up with his sperm, every last drop. She needed it because… no, first, she had to hear him say it.

                    “Tell me… call me a slut,” she said, drawing a intake of breath in a hiss as she said the word for the first time. That was it. The thing she’d been searching for. No answer in research or understanding before. That was what she wanted.

                    “What?” The request seemed to pierce Lucky’s veil of weariness, enough to make him blink his eyes and shake his head, trying to regain his consciousness properly. The sudden realization of a particularly sharp grind of Twilight’s hips made him groan and loll his head back, and Twilight leaned in towards his ear, whispering the words to him again.

                    “Please. Call me a slut. I need to hear it, please, I need you to tell me.” Twilight traced her hooves over Lucky’s chest as she spoke, running them in circles around his nipples while drawling languidly into his ear.

                    “Twilight, you-“ Lucky’s sentence faded into a groan as Twilight bobbed her ass up and down with sudden intensity, burying Lucky’s cock inside her over and over again, the head disappearing inside her every second as she hammered her hips downward.

                    “Tell me!” she yelled, her voice burning with insistence. Lucky was leaning his head back fully now, and on the side Twilight could see where he had hit the table, a patch of blood dripping down his scalp.

                    “You…”

                    Twilight grasped Lucky’s head in her hooves and threw it sideways into the table next to him, his skull hitting the wood with an unpleasant crack. Lucky made no sound, simply falling back as Twilight continued to bounce furiously on his cock. Wearily, he raised his head again, more blood now pouring from the now enlarged point of impact. “You… Twilight…”

                    “Tell me!” Twilight screamed, grabbing Lucky’s head again and pulling back to throw it towards the table.

                    “Slut! You’re a slut, Twilight,” He stammered, his words partially garbled through the haze of his cognition now jarred through multiple impacts with the table. Twilight released his head, letting it fall the ground where it landed against the wood floor unpleasantly.

                    She came as she heard the words, her vagina clenching around Lucky’s shaft and soaking him in another spray of liquid. It was more than he could take, and with a feeble groan his balls emptied themselves, spewing a load of hot thick semen into Twilight’s pulsing insides.

                    The feeling of being filled up with Lucky’s exploding cock, as well as a full geyser of his cum sent Twilight reeling. Her head thrashed back and forth wildly as she rode out her orgasm, moaning and screaming and grasping at her own body with her hooves in an insane display of pleasure, howling loudly as her pussy twitched again and again. Lucky’s cum mingled with her juices as it leaked out, coating the colt’s stomach with its volume.

                    The orgasm was the last thing Lucky’s mind could keep him awake for, and as his cock deflated he faded into unconsciousness. Twilight sat atop him for a moment, her hips still shaking, strands of semen leaking out of her slit. Lucky had been hitting her so deep, most of it remained in side, but due to the size of the deposit, there was only so much her body could contain.

                    Gasping for air as the remnants of her orgasm subsided, Twilight waited only a moment before repositioning herself, turning her body about completely and bringing her mouth to Lucky’s cock, licking around the base of the shaft and gobbling up the pool of semen and her own juices that had been left behind. Her hoof found its place between her legs, and she began rubbing her clit frantically as she licked up the sticky mess.

                    “Slut, I’m a slut, such a good slut,” she mumbled to herself through mouthfuls of cum, frigging herself frantically on the way to another orgasm as Lucky lay unconscious beneath her. She came twice more before finally leaving, staggering out the door to the colt’s house and leaving him unconscious beside the coffee table.
