You explore the castle thoroughly, searching high and low. It's surprisingly empty for such a large building, but then again Twilight doesn't seem the type to feel comfortable having servants. You're just about to give up when you spy a pale purple thing in the corner of your eye. It dips away as you notice it and you realise it's a pony.

Approaching the mysterious shy figure, you soon break into a run as she begins feeling. Through each twist and turn she's gaining distance from you and you almost feel dizzy. The filly then skids down the stairs, her horn lighting up too late. She crashes into the wall comically and sits there, dazed, giving you long enough to get a good look at her. A pale purple unicorn with her purple mane streaked with aqua and styled in two cute pigtails with a matching fringe. It's clearly Starlight Glimmer, and you can't help but feel your heart flutter at how sweet she looks.

As you stand there admiring her, Starlight stands up and pouts at you. Wait, is she blaming you for her crashing? She rubs one foreleg against the other awkwardly then takes a deep breath and says what's on her mind.

"I didn't expect you to come back, big sis!" her eyes begin to water. Wait what? She's getting so emotional so suddenly. She gallops towards you and wraps her hooves around you in a hug, sniffling, "Sunburst never came back... But you did!"

It all makes sense now. Since the ponies here believe you to be their sister who was gone for so long, Starlight must feel even more betrayed than she already did. You stroke her soft mane comfortingly and she looks up at you warmly, wiping her tears. It's a calm and happy moment, but you know you were sent here for a reason, and it wasn't to be wholesome with the fillies.

You push Starlight down onto her back and she squeaks in surprise. You can tell she has a bratty nature and needs to be taught a lesson via a good fucking. You begin hoofing her pussy hard and she squirms and wriggles uncomfortably.

"Bog sis you're too rough!" she tells you angrily but you know this is the right way. The tip of your hoof is angled and dipping between her folds everytime you thrust it forward. Starlight puffs her cheeks at you, face red, but she's becoming just the tiniest bit damp.

While Twilight was a good filly and you did your best to keep her comfortable, you feel the need to punish Starlight for her selfish behaviour. You force your hoof against her opening as hard as you can, and continue to push back and forth despite her struggles until finally you're inside of her. If you couldn't fit your hoof inside of yourself, it's definitely hurting Starlight, but if she can endure it surely she'll become a better pony later on. At least, that's how it goes in those weird fanfics you read.

Starlight is sobbing but you can feel her clit twitching against your foreleg. She's enjoying this even if it hurts, and some of her weeping sounds more like soft moaning. You keep working your hoof while also reaching down to lap at her clit gently. She lets out the most adorable squeak as she begins to tremble, and this coaxes you on to lick more.

The gentle squishing sound as your hoof pounds Starlight's impossibly tight insides is like music. Her flesh is stretching so much each time it pulls out a little, and then when it goes back in her pussy folds crumple up. Starlight is moaning away too, clearly far sluttier than Twilight even if she'd never admit it.

"A-Ah big sis! That feels so weird~" Starlight groans confusedly as you get deep enough to rub against her cervix. Realising, you instead bend your hoof to hook her g-spot instead and continue on in a nice rhythm. You begin to rapidly pick up speed as Starlight's voice raises in pitch and she starts kicking her legs.

You lick and suckle her clit like a teat, seeing her belly protrude as you push upwards and inwards with your hoof, finally pushing Starlight over the edge as her insides become like a vice around your hoof, fluid coating it as she shakes violently and cums hard.

You stand up to leave but Starlight grabs your leg and looks you straight in the eyes. She pauses then says, "Big sis you're not gonna leave without feeling good too?"

You did just cum twice with Twilight, but hentai protagonists never get tired and you want to make sure Starlight does all she needs, so you oblige by rising up onto two legs and pulling one pussy lip to the side. Starlight gets the idea and cups her mouth over your mare parts, reaching her tongue in deep right away. You place a hoof on the back of her head to keep her steady.

Starlight wiggles her behind just to make the situation better, and you show your appreciation by pushing her head against you harder. It feels do good to have an adorable little filly being so submissive when you know she has a far bolder personality underneath.

Your hips are rocking back and forth and you feel that familiar tingle beginning to stir in your belly. You push Starlight even harder with both of your hooves against her head, grinding your hips against her muzzle as she licks every angle of your pussy. Finally you arch your back and cum hard, legs shaking. You get back down onto all fours as Starlight flops to the floor.

Exhausted, Starlight lies there, her chest heaving. She's definitely satisfied now, thus your work is done. She does look cute when tired out like this, though, so before leaving you take her back into the room with Twilight and lay her down with a blanket.

Now it's about time you explored outside of the castle, so you rush to to the entrance with anticipation.

Smol Starlight has twintails and that makes her too epic
