The Naughty Royal Sisters

With her hands securely bound behind her, Luna felt Celestia’s magic brush against her side once more, keeping her legs spread apart. As she watched on with bated breath, Celestia watched as a few droplets of arousal slipped from her folds. “Now, you are not allowed to use magic unless I ask you to. If I see your horn light up, I will make it so that you would not dare to defy me again. Is that understood?”

“Yes, mistress,” Luna panted softly.

“Perfect. I am going to go slip into something more suitable for tonight’s events, though I am not going to leave you here without giving you something to do.” Lighting her horn, Celestia grinned as she grabbed Luna’s vibrator from her nightstand. She placed its tip right up against her clitoris, then used another spell to duplicate the toy twice. “We are going to do this the old school way...” Celestia said, making three short strips of duct tape appear out of thin air. She taped the other two vibrators onto the bottom of Luna’s feet, then turned them on low with her fingers as she secured the last vibrator on her sister’s pussy. With a quick spell, Celestia put that vibrator on its third fastest setting, making her sister tense up and moan into the pillow. “Perfect! I shall be back soon. Be a good sub and have as many orgasms as you want. If I do not see these sheets soaked by the time I get back, I promise that you will not get to cum for the whole night.”

Once Celestia had teleported away, Luna let loose a throaty moan, long and loud. Part of her felt a little naughty, knowing that the guards outside could hear her, and that same part of her wondered if they were fighting to control their cocks from peeking out from between their legs. She pushed herself forward, the tips of her nipples brushing against the sheets, making a shiver run down her back.

She let a sly grin appear on her face, for she was going to turn the tables on her sister.

Luna bucked her hips back and forth, but found that she was unable to get any sort of additional stimulation. With a roll of her eyes, she rolled over onto her back just in time to see Celestia teleporting back into the room, wearing a full set of black lingerie, complete with a set of high-heels.

“Now, my cute little sub...” Celestia stalked forward, her eyes locked on her prey. She turned the vibrator on Luna’s pussy up a couple of notches, then sat down on top of her sister’s face. “Do you like my crotchless panties? I bought them for exactly this kind of situation...” she murmured, running a couple of fingers through Luna’s hair.

Luna nodded, her lips less than an inch from her sister’s softly-throbbing pussy. Celestia’s panties were the definition of perfection, for two small strings ran on either side of her engorged labia, making them just a little bit more puffier than usual. Luna felt heat radiating from her sister’s pussy, and as she stared at it, her gaze locked on her cute little love button of a clitoris, a single drop of her sister’s sweet arousal slipped from her opening and landed right between her lips.

“Now... eat...” Celestia whispered in a commanding tone as she ran the tips of her fingers across her sister’s face, spreading her legs further apart. As soon as her folds brushed against Luna’s lips, she felt her tongue slither right inside of her, sending a small tremble up her back. Her breasts threatened to slip from her shelf bra as she leaned over, forcing herself to keep herself in place as she felt her clitoris brush against her sister’s nose over and over again.

Luna absolutely loved the taste of her sister’s juices, and part of her wanted to be given such a blessing every single day. Although, if they got careless about such a thing, then all of Equestria would most likely know by next week.

Luna felt her pussy leak more of her juices at that thought.

She pulled her tongue out of Celestia’s now sopping wet pussy, noticing that her bonds felt a little looser. With her heart racing in her chest, she smirked and wrapped her lips around Celestia’s clitoris, praying for a lapse in her sister’s magical grasp on her that she could switch the roles around and have a little fun. When Celestia let loose a soft moan, Luna felt her sister’s magical strength wavering, as if she was getting close to squirting all over her face.

With one final lick along Celestia’s pussy, Luna opened her wings and pushed herself up, knocking Celestia onto her back. She lit her horn and took advantage of her lapse in concentration, then secured Celestia’s hands behind her back with a spell even more complex than the one Celestia had used on her, just as an extra precaution.

Celestia let out a soft squeak as her eyes went wide, watching her sister as she stood up, ripping the vibrators from her feet and pussy. She noticed a sly glint in her eye and came to the realization that she was no longer in control. “Now, Luna, I forbid you to-mmmph?!”

“Now, now, enough of that...” Luna whispered seductively. “I am the one in control now.” She lit her horn and pulled a riding crop out from under her bed. “Be a good girl and show me your cute slit.”

“Like this?” Celestia asked, rolling over with just a little bit of difficulty she pushed her ass into the air, still a little peeved that she had allowed Luna to take control like this.

“Perfect...” Luna purred as she whipped her sister’s butt with the riding crop, three hits on each cheek. She lowered the leather tip to her own pussy and coated it in her sweet nectar, then ran it through Celestia’s feathers until it was dry. “Since you’re now marked with my scent, I want you to moan like the slut you are, and when I am satisfied that you’re a bigger slut than I am, only then will I give you release. Oh, and by the way...” She reached around and unclasped her sister’s bra, letting it fall to the sheets. “There’s no need for that anymore,” she said, grabbing her sister’s breasts with her magic, kneading the soft tissue and teasing her rock-hard nipples with the slightest of touches from her magic. “On second thought... maybe I should give you a reason to moan for me...”

Luna tossed the riding crop aside and used her magic to pull out a thick pink double dildo from beneath her bed. She lubed it up with some lube she had in her nightstand, then while she held the dildo up in the air with a small spell, she worked a few fingers inside of her sister’s ass, spreading it apart so that she could squirt no small amount of lube inside. Once she was sure her sister’s rear entrance was properly lubed up, she did the same to herself, letting out a soft moan as she rubbed the dildo between her lower lips, ensuring that Celestia’s end was coated in her arousal.

She got on her hands and knees, then backed up until her butt bumped against her sister’s. “Now be a good slut and moan as loud as you possibly can as I make you feel fuller than ever before.” With that being said, Luna used her magic to gently work the double dildo inside the two of them, her eyes going wide as its tapered tip finally slipped inside of her. After using this toy at least a few times a week, she found that she was able to push herself all the way down to the middle of the toy with little hindrance. With her ass stuffed full, she clenched down and pushed back, making Celestia squeal out in pleasure as she bottomed out on the toy as well.

Luna smirked again as she wove her tail around her sister’s. Eyeing the many candles around her room, she used her magic to grab one, levitating it over her sister’s back. With another spell, she formed a life-like tongue that incessantly licked her sister’s clitoris, knowing that each lick would push her closer to her inevitable orgasm. As an afterthought, she did the same to herself, immediately feeling her nectar drip from her folds.

Slipping a few fingers inside of her wet slit, Luna fingered herself as she bounced back and forth on her favorite toy, Celestia’s moans sweet music to her ears. Her vision blurred as she felt her orgasm rise to the forefront of her core, and as she slipped over the edge, she felt the backs of her legs grow wet with her cum. With a sigh of content, she collapsed, the dildo slipping from her rear.

Celestia trembled, doing her best to hold onto the dildo with her butt’s muscles, though it was a losing battle. It slipped out of her, inch by painfully slow inch, before Luna’s magic pushed it back inside of her. She felt it speed up until it plateaued at a fast pace, fucking her in deep, long strokes. Celestia felt her orgasm grow, faster than ever before, when suddenly her sister’s magic faded away. “Ugh, s-sister!” She shot a glare over her shoulder.

“Oh, relax, I was simply teasing you!” Luna said with a giggle. She added more lube to the toy, then let it keep fucking her like before. She leaned in and lay down behind her, pulling her sister’s ass down until she could reach her wet pussy. Luna plunged her tongue into Celestia’s pussy as deep as she could possibly go, then moments later, she came.

Luna sat up, leaving her sister’s cum on her face. Not bothering to clean her lower regions, she used her magic to blow all of the candles out, then snuggled up beside her sister, wrapping her in her arms and wings. She pulled a couple of pillows over for them to share, but Luna discovered that Celestia was already out cold. “Heh... must have been one heck of an orgasm...”

As the morning’s light streamed in through her bedroom windows, Luna stirred awake, her sister still sleeping away in her arms. She folded her wings back to her side, then lit her horn, using her magic to rub Celestia’s clitoris in small, tight circles. Celestia stirred awake with a soft smile on her face which Luna quickly interrupted, stealing a tender kiss from her soft lips. “Ready for round two?’ she asked with a mischievous smile.
