Yeah, timecest. Having sex with time. Yeah, I'm making it a thing, just like Twilight banging a scroll.

Starlight needs a break from all the friendship lessons, so she does some exploring with her time spell. Turns out, you can do some kinky stuff with time...there's also self-cest.
Contains: self-cest, time-cest, using spells on private areas, vaginal shrinkage/aging (for months of anticipation purposes, not some freaky-ass Granny Smith stuff) and light BDSM self-cest.
Don't worry, it's the good kind of weird.

The Time Scroll

Starlight sits with a grumpy look on her face, as she gazes over the crystal table in Twilight's castle. She props her head up with one hoof and sighs.

"There has to be something to do around here, but I can't find a single thing that peaks my interest! I know I'm supposed to get involved with these ponies, but there's no way to have some me time without bumping into someone or being bored to tears in Twilight's castle!"

She lets out another annoyed sigh as her gaze bounces from random bookshelves to each tiny throne. Suddenly her eyes open up as her jaw hangs open eagerly.

"Maybe there isn't something to do right now, but perhaps I can find something to do with the future!" Starlight bits her bottom lip happily, and with a flash of her horn, the timescroll appears before her.

"I really hate lying to Twilight about how I destroyed this thing but..." Starlight's face contorts into a look of concern. She taps her hoofs anxiously on the table as the scroll and its sensual musty aroma calls to her. Her eyes wince as she finally gives in and casts magic on the scroll. A portal opens up above her and sucks her into it.

The portal exits above a tree. Starlight cries out as she starts falling. Before she can levitate herself, her flank gets smacked by one of its branches. She lands on the ground, her haunches trembling valiantly. She bits her bottom lip and looks back at her flank. She lets out a few quick gasps. She sticks her bottom high into the air, enjoying the wonderful sting on her cheeks. She buries her face into the ground, wiggling her haunches left and right, silently crying out for more. She levitates herself back up, and carefully drops herself, colliding once more with the branch. She lets out a ferocious howl of pleasure. She lands on all four legs, but the wonderful buzzing pain on her cheeks makes her wobble before collapsing. She lies there, panting wildly.

"Alright I...I need to...find an easier way..." She looks around and gets an idea. Her horn flares and she levitates above the tree. She squints her eyes in concentration. A portal forms above her, and several feet below the branch, exactly where she knows she'll fall.

"Okay...here it goes..." She lowers her shield and falls. The air comes alive with a sharp smack, as Starlight once again hits the branch. Her cheeks wiggle violently. Starlight opens her mouth and cries out with all her might. As she drops into the bottom portal, she falls back through the first portal she made. Over and over, the branch spanks her cheeks. Bark begins to fall off the branch, with Starlight crying out over and over. She gasps at both the wonderful sting on her bottom, as well as the delightful smack every time she gets thrown back through. After a minute, Starlight closes both portals and lies on the ground. She turns onto her stomach, once again waving her flank around, dying for anything to play with her moist interior.

She grits her teeth angrily.

"I'm...I'm too tired to keep going. If only there was some way..." Starlight gasps as she hears a few leaves crunch ahead of her. She looks up in embarrassment, only to stare confused at what was clearly herself. Her copy smirks as she casually trots over to the helpless mare who's overcome with exhausted lust. She can do nothing but gawk, as her duplicate casually trots over. Her haunches shakes as herself's eyes travel over her body.

The second Starlight walks around the mare, sticking out a hoof and dragging it across the mare's backside. She instinctively raises her cheeks higher into the air, unable to resist the urge to present herself.

"Looks like you could use some...help." Her counterpart teases aggressively. The unbearably aroused mare can do nothing but squeal quietly in response to being touched so provocatively.

Starlight raises an eyebrow and grins at her former self's backside. She raises her front hoof and spanks the helpless mare's moisture with the top of her hoof. The mare cries out repeatedly.

"Please...please...do something! I can't...I can't take this anymore!"

The second Starlight laughs playfully and with a hint of cruelty, enjoying her new play toy. She walks around to her front and hunches to the ground.

"You're going to have to earn it you filthy mare." Starlight taps her hoof and grins.

"Suck it. And suck it hard or you're not getting anything slut!" Starlight stares at the horn, before opening her mouth and letting her tongue hang out. She raises her head from the ground just enough to carefully lift the horn into her mouth. She closes her eyes, letting the hard tip caress the roof of her pallet. She trembles as her lips slide across the smooth surface. She slides her mouth down to the tip of the horn, before slowly sliding her lips across it once again. She stops as her second self presses an angry hoof onto her head, forcing her face to the ground. She looks up in fear.

"Suck it harder!" Starlight trembles as she gets up, loving the sensation of being ordered about as some helpless slut before her master. She takes the horn in her mouth once again, bobbing her head back and forth as fast as she can. Her lips sting as they repeatedly grace the exterior of the horn over and over. Her second self lets her tongue hang out of her mouth as she pants. The vibration of her horn being sucked sends waves to her flank which begins bouncing up and down with anticipation. Starlight takes her lips off the horn, and drags her tongue eagerly across its firm exterior. Starlight tilts her head back and sticks her tongue in the mare's mouth. They massage each other, enjoying the warm, slippery sensations in their mouths. Starlight takes her tongue out of the mare's mouth and gives her a slow kiss before getting up. She trots over to her flank and runs her hoof up the mare's right cheek.

Starlight lowers her head, and slams her horn inside the mare. Starlight cries out. Leaves crinkle beneath her after every powerful thrust from her other self. She opens her mouth wide and lets out screams of erotic joy. The horn slides in and out of her, causing the mare to arch her back as to gain as much traction as possible. The horn makes a light smacking sound every time it enters. Starlight reaches up and massages the mare's rear with her hooves, loving the smooth, round figure in front of her. She pulls out her horn. Her cheeks glow red as she pants, dying for her turn. She gets up on her rear hooves and swings her right leg over the mare's bottom.

She crouches down and allows their opening to grind against one another. The surrounding hills echo back the mutual cries from the mares. Starlight grinds herself back and forth as if trying to dig into the mare. The shameless slut below her looks up and drools, loving the feeling of a leg grinding between her cheeks. She flexes her haunch muscles, letting her feel the leg bouncing between her cheeks even more than before. The silky fur of the leg makes the grinding nice and smooth, as her calf muscle flexes wildly against the mares backside. Liquid begins to slowly dribble down Starlight's leg, as she grinds against her captivated self. She closes her eyes and forces herself back and forth as fast as possible. Both mares almost scream over and over, letting out years of pent up tension. Starlight bends her head over and drags her tongue across the mares left cheek repeatedly. She drools, loving the feeling of a nice battered flank against her tongue.

She stops grinding and lifts her leg back to the ground. She gives the mare's flank a nasty smack with her hoof.

"Alright...my turn..." She says while panting. Starlight raises herself off the ground. Her legs tremble and barely allow her to stand. They swap places and Starlight raises an eyebrow.

"I...I have an...idea..." Starlight's horn lights up and a beam of magic hits her second self's clit. It vibrates violently and the mare tries to scream to her other self.

"Wh...what did you do!?" Starlight smirks at her handiwork.

"Technically, I made your nether regions three months older. That anticipation must be killing you hm?" The mare batters the ground with her hoof as she cries out desperately.

"Do...do something! Touch me, do anything! I can't take this!" Starlight chuckles to herself.

"Stay Starlight Glimmer is the best, smartest pony ever or no treat for you." Starlight grits her teeth and looks over her shoulder desperately.

"St...Starlight Glimmer is...is the best and smartest pony ever, oh sweet Celestia do something to me!" Starlight laughs as the eager mare attempts to slowly back her flank to her, in an attempt to get some form of gratification. She strokes the mare’s clit with her hoof, intentionally being too gentle.

"Please! Please! I'll do whatever you want!" Starlight chuckles again before tracing the mare's right cheek with her hoof. She stares at the mare's opening, before tracing its ridges with her tongue. Her victim cries out as her clit throbs a few times. Starlight slowly drags her tongue across the opening, getting more and more firm with every lick. The mare lets out high-pitched squeals, enjoying the pleasure, but knowing it's no substitute for a good horn pounding.

Starlight pulls her tongue back, before drilling it deep inside the mare, who lets out a deep moan. She digs her face into the ground, letting out long grateful bellows, as she feels Starlight's tongue twist and turn inside her. Starlight has to hold onto the mare's flank to stop her from shaking loose. The mare's cries are almost muffled by the ground. She howls as Starlight widens her tongue inside the mare. She wiggles it up and down, occasionally slapping the mare's ass with her hoof. She forces her tongue as far as it will go, as the mare before her goes wild with grateful screams. Starlight wraps her forelegs around the mare's waist, and lifts her off the ground by a few inches. She makes the mare's head roll behind her, before lowering her to the ground again.

The mare now stares up at her own opening, as Starlight looks down at her. She traces the mare’s bedazzled face with her hoof while grinning.

"I want you to watch..." Starlight says with a satisfied smirk. The mare holds up a helpless hoof.

"W...wait...I...I have an idea..." The mare's horn glows briefly, before her clit is consumed by magic. Starlight cocks an eyebrow and watches. The mare's clit slowly shrinks, even looking quite a bit younger. Starlight looks down at the mare.

"And just what exactly was that?" The mare lets out a few week chuckles.

"Just turned time back is all, so I'm nice and tight for you." Starlight stares at the mare bewildered before biting her lip mischievously. Starlight looks down at herself one more time, before slowly sliding her horn into the mare. She grunts a bit, having to put more effort into it. The mare's mouth hangs open, almost choking on her own words. Her eyes grow wide and her body begins to convulse. Starlight squints her eyes in concentration, trying to force her horn into the mare. The mare’s legs twitch a few times as she does her best to ignore her instincts to pull away.

Starlight finally gets her entire horn inside the mare who screams in a mix of both pain and satisfaction. Her legs kick wildly above the pair.

Her eyes close a bit and her tongue hangs out of her mouth, flopping up and down with every vigorous thrust from Starlight bits her lip, enjoying the wondrous sound of her tight clit being almost forced outside of its normal limits. The mare tosses her head back and forth, her tongue slapping the side of her cheek. Starlight stares down at her, and manages to grab the mare’s tongue in her mouth. She sucks on it eagerly while continuing to pound the flailing mare. She begins tossing herself back and forth, before clamping on to Starlight with her hooves. Her quiet cries get louder and louder. Starlight slams her horn in and twirls it around in big circles.

The mare’s cries are almost ear shattering. She clamps onto Starlight, as moisture from her clit slowly makes its way down Starlight’s muzzle, onto the chin of the enthralled mare. She lets out one final long cry as her muscles sense and her body shakes violently. Starlight lets go of the mare’s lower body, which collapses to the ground in a hot, wet mess. She lies on her back panting heavily. The mare stares up at Starlight, who has heavy breathing of her own.

“Until next time?” she says with a seductive raise of her eyebrow. The mare shakes her head.

“You forgot, I’ve already done all this. You still need to go back in time and...help yourself remember?” Starlight narrows her eyes in confusion before chuckling to herself. She gives the mare a long, deep farewell kiss.
Her horn flashes and a portal forms above her head. Starlight is sucked in and immediately lands on the ground. She glances around at the same familiar tree as before. She takes a few steps forward, watching a copy of herself on the ground, ass sticking eagerly in the air. Her other self looks up at the sound of crunching leaves. Starlight cocks an eyebrow.

"Looks like you could use some...help." She teases aggressively.
