The best part of waking up, is a hoodlum in your arms.

Rarity woke up with a start in the middle of the night. She didn't usually wake up due to her being dead tired from a large amount of work making the most perfect dresses in Ponyville, to which she would usually just fall unconscious on her bed and sleep soundly until the morning. Luna's moon shone a brilliant light upon her room, casting vague silhouettes and shadows around objects in her room. Scattered tools of her trade and unraveled fabrics had littered the ground.

Perhaps the extra work she made herself go through would have been enough to  calm the raging intensity between her loins. She was in season, and rather than find a magic spell, a potion, or a stallion, she instead wanted nothing more than to work hard enough to forget the intensity that her crotch had burned throughout the day. Yet something was amiss; Rarity could feel it around her. Her stress-filled day and night before should have made her sleep soundly this night, but there was a small noise and a shuffle underneath her blankets that had disturbed her, Along with a more intense heat that wasn't in her loins, but rather wrapped around her waist. She felt something against her back, something cold and hard...

It was then that Rarity had lifted her blanket up with magic, and startled by the sensation of cold hooves on her back that drove a mild tingle up her spine and made her hips shake, she had roughly shoved the body off of her bed in fright. "W-What are you doing!? Unhand me ruffian!" she shouted, much to the loud squeak of surprise and grunt as whomever was wrapped around her had been roughly shoved off her bed.

"Aaaah!" shouted the small unicorn. "R-Rarity, Wait! It's me, Sweetie Belle!" she said, and not a moment too soon as Rarity had advanced on the little filly with a mannequin lifted above her head, glowing with a faint light blue of her magic.

"Sweetie?" Rarity said, lowering the mannequin down and looking at the filly who bathed in the moonlight. She let out a soft sigh as Sweetie came into view, and sat there and stared at her. "What were you doing, sneaking into my bed?" she asked while taking a few breaths from her nose to relax herself after the sudden burst of adrenaline.

"I came to sleep with you Rarity! I had a bad dream and I was too scared to sleep by myself."

Rarity could only sigh. 'What a big baby' she thought to herself. Almost as annoying as when she had lived with her in her parents house, before she bought the boutique. She absent mindly made the bed again with her magic and said to her little sister "Alright, I suppose you can... just... please ask next time, sweetie belle. You gave me quite a fright." Sweetie beamed with happiness as she dove right into the bed before her sister climbed in after her.

Rarity had gotten comfortable in her own bed and faced away from the little filly; Sweetie content with turning the other way and facing the wall too, as to not disturb her sister's comfort zone. Rarity, having not shared a bed with her little sister since forever ago when they shared a nightlight in their parents house, couldn't fall asleep. The burning sensation in her nethers did not help the situation any. With nothing to do to occupy her mind, and unable to fall asleep from the startle sweetie gave her, she resorted to tossing and turning, and biting down on her pillow and sheets.

Then a rather perverted idea came to Rarity's mind. There was a warm body next to her on her bed, and she hadn't been with a stallion in forever. Sweetie belle wasn't a stallion of course, but that minor detail didn't register in her heat filled mind. It was becoming unbearable and uncontrollable in her mind. she couldn't bear the heat any longer, and the little filly next to her was making the situation worse.

Slowly, the unicorn sighed deep, and slowly rolled over, her heart beating into her chest hard as she slipped her hooves under sweeties sides in a gentle hug. Sweetie giggled softly and cheerfully, unaware of her sister's intentions and liking her sudden affections towards her. Until rarity made her a little uncomfortable by holding her close, hugging the soft little filly close to her chest and giving the back of her neck a nice, long lick, sending hot breath down sweetie's neck. Rarity started to softly and slowly grind her hips against the little filly's legs, her tippy hoofsies being around the area of her pelvis which made her shudder all over her adult body.

Sweetie felt the hairs on her neck and all along her spine all stand outwards. "R...Rarity?" sweetie belle asked, her neck being licked and matted down, her tummy being clutched a little too hard for her liking, and the soft movements to her hoofies making a small tinge of fear enter the filly's mind. She smirked though. "I... I don't mind snuggling, But can you stop licking me? I'm not grass silly!"

Rarity halted all of her actions and froze. She kept frozen for what seemed like seconds, even minutes before sweetie belle got worried. Then very, very suddenly, Rarity had moved on top of sweetie belle and moved her hooves down on the tiny unicorn's own hooves, pinning them down as she kissed and licked at her soft little neck. Her hind hooves being kicked by the smaller filly's tiny ones in surprised struggling, and her tummy was pushed down into the soft bed with her hips.

"Stop." Rarity commanded, with sweetie asking what she was doing, and telling Rarity to let her go.

"I said STOP!" the unicorn shouted into the night, taking one hoof off Sweetie's hoof and slapping the childish face of her sister, so hard that a small horseshoe print had formed along her cheek. This made the little filly stop and look at her usually loving sister in tears.

"R...Ra..." Sweetie Belle started, before Rarity had moved down and forced her mouth on sweetie belle's, slipping her free hoof to her own heat filled nethers as she kissed her little sister on the mouth and danced tongues with the little filly's panicked tongue. She licked from the tip to along the sides and underneath and suckled the now sobbing filly's tongue-tip, trying to apply what little about kissing she had learned from her romance novels.

Pulling away, The menacing unicorn started to compliment and hush her little sister, with an effort to calm her down by stroking her mane. "Shhh... good little Sweetie Belle. Just stay still for your sister..." she said, lighting up her horn and glowing that soothing light blue magic around the filly's young neck, only so she could force her down and keep her in place. She went down, skipping past all the foreplay and went right in, diving into the filly's nethers and roughly biting and licking her.

The poor filly could do nothing but sob and look to the ceiling, not able to look down with the forceful telekinesis pushing her down towards the bed. She squirmed uncomfortable as her nethers were poked and prodded at, and shouted in pain as she was bitten and roughly orally taken.

Enough was enough for rarity. Even her hoof couldn't do anything to sate her raging inferno of a heat, no matter what she did. She let go of sweetie belle's neck with her magic. Sweetie Belle thought of running away from her situation right now, but it would be difficult to outrun the power of the older unicorn. Rarity put a stop to any of Sweetie Belle's escape attempts by turning sweetie belle over roughly with her hooves and pulled her over to her hips, and as soon as sweetie belle was in place, Rarity shifted her weight on the bed over her.

Sweetie Belle was incredibly confused. What was she doing? Why was her sister doing this? "R..Rarity, Please stop! It hurts!" she said with a childish whine, but Rarity just bit down at sweetie's neck and started to comfortably slide in place over the young filly, using her magic to lift her soft little flank upwards.

"Shhh... It's okay Sweetie Belle." Rarity hushed into the small filly's ear with hot breaths, lining up into position as she spread the filly's legs apart and pushed her hips, and her crotch, up against the little white filly's own underdeveloped crotch. "B...Buck! You're so... So soft my little sister!" Rarity said with a shake in her voice, almost as if she had to force the words out.

The little filly let out a pained whine as her hips moved up and she was in a compromising position, but still she protested in the form of a small struggle as she was mounted like a stallion does with a mare. Rarity had pulled away much to sweetie belle's relief and suddenly sweetie had felt a small smack against her soft bottom. Then another. Rarity was soon humping against sweetie belle softly, then more roughly, slapping her hips against Sweetie's small filly nethers. The thrusts of Rarity's marehood was touching and grinding against the underdeveloped filly's marehood, making little sweetie belle's whines and whinnies release loudly into the uncomfortably empty room. The sounds of sex and heavy breathing now about as intensified as Rarity's heartbeat as she claimed her little sister, rubbing her sensitive little nub against sweetie's tiny one roughly, making the filly cry out more tears as emotions she'd never felt before came washing through her now tingling body. She sobbed, gripping ahold of the pillow in front of her and biting into it to stay quiet like her big sister had ordered.

Rarity had gone on and on trusting hard towards her own orgasm, building up to something that she's been wanting to do for the entire day, but never got around to. She panted and moaned into sweetie's ears, commenting on the smallest things to heighten her arousal as she turned them into dirty bedroom talk.

"Your ass is so F-Fucking soft, You little whorse! I bet you... I bet you love it when your sister mounts your stupid mule ass!" she says, trying to degrade her little sister. Sweetie's ass and nethers now hurt from hard, repeated tribbing against her sensitive areas, until Rarity put both hooves upon sweetie's head and started thrusting against her harder, and harder, dominating her against her bed.

Rarity bit sweetie belle hard against her soft little neck, feeling a wave of relief wash over her adult body as she ground and pushed sweetie belle into the bed, the noises the bed was making slamming against the wall fallen on deaf ears as she came all down her nethers and all on sweetie belles legs. Her ears had rung from a mind blowing orgasm as she finished raping her younger sister. Rarity slowly rolled off of the crying filly's body and laid on her back. The big unicorn started to pant from both sating her burning heat and from her own exertion. They were both covered in sweat, as well as both of their hair being frizzly and unkempt from the activity they indulged in.

Now with her heat out of her mind for the next few seconds... 'W-What have I done?' Rarity thought to herself, breathing in hard breaths as she felt the afterglow of her filthy act. A huge wave of guilt rushed throughout Rarity's body. Her eyes started to water at what she had done.

"S...Sweetie?" she asked, looking over towards her little sister. Sweetie had been in the same place with her now reddened bottom up in the air, still crying from having her trust betrayed by her sister. "Sweetie Belle I... I'm sorry."

Sweetie Belle said nothing, Just rolled over and faced the wall, back turned to rarity and curled up with her hooves to her little legs.

Rarity sighed and looked over to the little filly. She had tried for the next several minutes trying to figure out what to say. Nothing came out. She did the only thing she could think of. She brought the blanket over towards them both, and spooned her little sister and covered them. Sweetie Belle cried louder, her soft little sobs echoing in the quiet room, and shook in Rarity's hooves. Rarity apologized over and over, kissing at sweetie's mane and holding her. Rarity tried to comfort her with soft little strokes and a lullaby.

A few minutes later, Rarity fell asleep from her fatigue and Sweetie Belle had finally stopped crying. Her sister really hurt her, and she really did not know what to do in this kind of situation. She really wanted to rely on her sister for support, but the very pony she'd want to confide in betrayed her trust and hurt her. Despite all of this, and despite what happened, Sweetie Belle moved and turned around so she could face her sister, and buried her tear stained face right into Rarity's chest and tried to fall asleep, tears still quietly forming in her eyes as she drifted off in her arms.
