Grumbling to herself as she laid on her bed, Star Butterfly flipped through the large magical book that was spread open before her. Her mother had repeatedly reminded her to study magic more seriously and at this point she was looking through it just to make sure the next time they spoke she could say she read it. Not wanting to deal with another lecture about the importance of mastering her abilities. So here she was, turning the pages and looking for anything that might catch her interest. Some of the previous queens had chapters that were interesting but bland. Others were far too complicated and threatened to put her to sleep if she tried to focus on them for too long. She briefly considered learning something from her mother's chapter but it leaned too heavily into the technical side and she was after something a little more impulsive. Something that had some spark and instinct behind it.

As her fingers kept turning and her mind drifted to various thoughts she realized that one of the pages felt thicker than the others. Curious about this she actually paid attention to the motion of the pages this time. Noting that there was a clump of them stuck together. "Huh, what's this all about?" Star asked herself, noticing she wasn't anywhere near Eclipsa's chapters that were regularly seen as restricted spells. Though she didn't understand why that one was sealed either. After a few attempts to force the pages apart failed, Star decided to actually read the text on the paper to see what the problem was. "'The following content is not for princesses under the age of eighteen'. Wait... why not!?"

Her attempts to force the pages open continued to be met with failure. Not deterred, she went to her desk to get a nail file to try and wedge it between to see if she could unstick the paper. But to her dismay it was like jamming the file into a side of concrete. "Boy, they really sealed this up with some strong magic. Figures, I actually want to read a chapter in this book and now they won't let me! What do I gotta be eighteen for?" Star grumbled. She'd waited years to get her chance to use the wand and now she was going to have to wait even longer to read this whole book? Oh no, not if she had anything to say about it!

Unfortunately the book didn't seem to care what she had to say. It was still closed up tight on that particular section. "Hmm... so I can't open it myself. But someone over the age of eighteen can?" Realizing this loophole Star got a mischievous grin on her face as she grabbed hold of the book under her arm and exited her room. Racing down the hallway of the Diaz household Star stopped in front of her bestie's bedroom. Raising a hand up to knock on the door her hand came down on something hard but it wasn't made of wood.

"Ow! Star!" Marco groaned, backing up after getting whacked in the head by the Mewni Princess. "What was that for!?"

"Oops, sorry, was just about to knock on your door to ask you something."

"Well you got my attention. What's up? I was about to go out to meet up with the guys."

"I was wondering if you could do me a teensy weensy little favor?" Star asked hopefully.

"A favor huh, well, sure. What did you need?"

"Can you turn this page?" Star asked, opening up the magic book to the portion that had been sealed away from her ability to open it.

"Uh... yeah, I guess so? But why do you need me to do it?"

"It's got a magic lock on there that won't let me read it."

"But I can open it when you can't?" Marco asked. The text to him was all gibberish. Written in Mewni's language so he couldn't tell the reason why it would prevent Star from continuing.

"Well yeah, you aren't me." Star said confidently.

"Are you sure you weren't locked out for a good reason?"

"Marco, this is my magic education we're talking about. Everyone is always going on and on about how I need to study more seriously and then they won't let me read the good stuff. Besides, what could be in here that's any more dangerous than what I do on my own already?"

"...fair point." Marco said, turning the page and noting the pink sparkles that seemed to fly out of the book as he did. "Whoa! So uh... I had the magic touch, huh?"

"You sure did. Thank you bestie!" Star said, giving him a big hug with an extra snuggle against the cheek for good measure. "Okay, you're free, go have fun doing boy things with boys. I got serious studying to do!"

"Well, so long as you don't explode the house I guess it's alright. See you later Star." Marco said as he walked down the stairs and out the front door of the house. Grinning excitedly, Star returned to her room and took her position back on the bed, looking over the now revealed pages. Certainly Marco looked the same age as her but after his time in the Neverzone, he'd aged to around thirty due to some time shenanigans between the dimensions. Thankfully for her the magic took that into account.

"Alright secret book section, what are you hiding?" Star asked aloud, reading the pages with renewed interest. Weirdly though she didn't quite understand why these spells had been hidden from her. There was a spell to make the wand vibrate which she didn't see as all that useful. Another one was listed as a way to revitalize your king in a time of need which while that sounded good didn't seem all that forbidden. There was one spell that was listed as the "last resort" for a queen on the night of her coronation. That one seemed particularly interesting. "A spell that will give you the fire and energy to crush a thousand men's spears in a single night? This one of those combat spells? Sounds kinda cool though." Star admitted, reading the casting instructions. Weirdly it involved a lot of touching yourself with the wand but maybe that's how it transferred the power to you. "Guess I'll try this one first."

Standing up from her bed Star turned the book to face her so she could look at the listed diagram of movements, much of it involving saying Mewman words while trailing the wand up both her legs against her inner thighs and even between her legs. As she continued the chanting the wand was drug up against her chest and then her neck, ending with a kiss at the end. There was a small, heart shaped spark of light not unlike the ones on her cheeks as the spell finished. "Ooh, pretty. Guess that means it worked." Star asked herself, looking her body over. "I don't look any more powerful, though. I thought I might buff up like Mina Loveberry or something." As she stood there wondering when things were going to happen there was a ring of the door bell. Mr. and Mrs. Diaz were out and with Marco having left she figured it fell on her to take care of business while at home. "Guess the lessons will have to wait."

Heading down the hall Star leaped on the banister and rode it down like a slide. Hopping off at the last second. "Ooh... goose bumps!" Star said with a smile, that little slide feeling better than she expected. Walking over to the door she opened it to see a familiar but unexpected face on the doorstep. "Ferguson?"

"Hey Star, good to see you!" The chubby, red haired boy said loudly and proudly. "I was here to pick up Marco."

"Pick up Marco, but he already leEEEEEFFFT!" Star stuttered out, suddenly feeling very strange.

"What was that?" Feguson asked her, looking more than a little confused by her outburst.

"Ma... Marc... Marco... he..." Star said in heavy pants of breath, suddenly feeling very warm. It was a weird sensation, one she wasn't familiar with. The last time she remembered a sensation like this was when she had experienced the intense transformation of Mewburty. But something was different about it. It was stronger, hungrier, and hotter. She couldn't place what was causing it but her body was growing warmer by the second.

"Hey Star, are you okay? Maybe we should go get you some help?" Ferguson offered, putting a hand on her arm. The touch seemed to activate something in Star's mind as she suddenly knew immediately what it was that she wanted and exactly what would relieve her tension.

"No, we don't need to leave." Star said, grabbing hold of Ferguson's arm instead and pulling him into the house. "You wanted to see Marco, right? I'll take you to him!"

"Whoa, uh, are you sure? You're looking a little feverish." Ferguson asked her, seeming truly concerned for her health.

"I'm fine I'm fine, let's just go!" Star insisted, pulling him by the arm up the stairs. Ferguson was confused but decided it didn't help to fight her. Especially with how much stronger Star proved to be over every other person he'd ever met. Running up the stairs after her, Star opened Marco's door to his room and stood aside for Ferguson to walk in. When he did enter it only took a quick look around to realize the room was empty of any other person besides themselves.

"Uh, Star, are you sure he didn't leave already?" Ferguson asked, confused but when he heard the door close behind him he felt even more lost. Turning around to see the blonde girl smiling at him in a way he'd never seen a girl smile before. It was strange, beautiful and in a way predatory.

"Oops. Guess he did." Star said, still smirking at him in that hungry manner. "We can wait for him here though. Why don't you take a seat?"

"I mean... I could just go meet him. He's probably at Britta's Tacos alread-" Ferguson didn't make it far as Star pushed him onto Marco's bed for him to sit down. "Or I could take a seat, sure!" Ferguson agreed with her forceful actions.

"Now... I should be a good hostess... and entertain you." Star said with a seductive tone in her voice, reaching behind herself and pulling down the zipper of her blue dress. Ferguson watched in awe as she let it drop all the way down her back and carefully slipped the straps off of her shoulders.

"Are... are you..."

"Done? Not even a little bit." Star finished for him, turning her back to him and letting the loose dress fall around her lithe frame. Her back was almost covered completely by her long blonde hair and Star took care to kick off each boot from her feet. Then wordlessly her fingers hooked into her tights, pulling them down to her ankles and kicking those off as well. When she turned to face him again she was standing in white panties alone while her hands covered her breasts. "Are you feeling taken care of so far as a guest?"

"Y-yeah..." Ferguson gulped, having never seen a girl this naked before. Sure he'd seen women in swimsuits but never someone with their top completely off. Letting her hands drop from her chest her breasts came into view, approaching him Star got on her knees where he sat. "I can see you're getting excited here. Guess you like girls with wings?"

"Heh... maybe I do have a thing for them." Ferguson said, trying not to panic as her soft hand was rubbing over his crotch teasingly. "There was that pixie queen I almost married but uh... she wasn't quite as... full figured as you."

"Oh I can do all sorts of things she couldn't have." Star said confidently, licking her lips. "Let me show you." Reaching up she unbuckled Ferguson's belt and undid his pants. Even though it embarrassed him a little, Ferguson leaned back and lifted his gut to allow her easier access, though Star didn't seem to mind at all. In fact she was grateful as it allowed her to pull his pants down that much faster. Leaning back on Marco's bed, Ferguson looked down his body to see Star pulling away at his underwear to reveal his erect cock underneath. "Found you! Looks like you're eager to see me, aren't you?" Star said teasingly, her soft fingers gripping around his cock and stroking it gently.

He'd never felt something so amazing as a girl's hand on his dick before and the stroking she did with it was incredible. It being such a beautiful girl too made it a dream come true for any boy looking to have such an experience. Though Star didn't stop there as her mouth opened wide to lean down over his cock and suck it into her lips. Her head moved up and down slowly as she let her tongue trace over the length of him and taste his skin. She moaned against him as her nose took in a breath of air and her head moved down again, sucking him hungrily into her lips over and over.

"Star... this is... amazing!" Ferguson exclaimed, not understanding why she was doing all of this but he was far too excited to refuse it. Star giggled a little around his cock and pulled her lips off of it with a wet pop. Stroking his member that was soaked in her saliva.

"You've got the good stuff for me, don't you?" Star asked him, sounding even more aroused than he was. "Don't hold it back okay, I want to... to taste it! I've never tasted it before but I know I want to taste it now!" Before he could even answer Star's head dipped back on to his cock. Her head bobbing up and down on his erect member repeatedly. The pressure was far too much for Ferguson to be able to resist and he gasped as he came inside of her lips.

"S-Star... I can't stop it!" Ferguson said as he continued to ejaculate into her mouth. Star's head was not lifting up as she let it fill her cheeks and closed her eyes tightly. Pulling her head back and keeping her lips sealed, Star swallowed the large load in her mouth and let out a sigh.

"So good... tasty... Mmm... but I'm still so hot." Star gasped, getting to her feet. "Wait... Wait here... just wait!" Stumbling towards the door, Star swung it open and disappeared out of the room. Giving Ferguson a second to catch his breath. He still had no idea why this was happening, was Star secretly in love with him? If so, was this going to make things weird between him and Marco? He sure hoped not. Before he could dwell on it any further Star came back into the room, wand in hand with a pink glow surrounding it.

"What's that for!?" Ferguson asked worriedly, Star having shown she had a talent for destruction when it came to magic.

"I learned a great new spell!" Star said, swinging the wand upward and smacking Ferguson right between the legs.

"Uurk!" Ferguson gasped, body recoiling up on to the bed with the sudden shock of the hit and the pain that came with it. Though funny enough it had passed soon after and Ferguson could see that his cock was completely erect again. "Wha... what was that?"

"A way to revitalize your king in a time of need, and it is definitely my time of need." Star explained, dropping her wand on the floor and pulling her panties down as quickly as she could. Ferguson only had a few moments to admire what she looked like completely naked before Star was already climbing over top of him.

"Hey, is it... is it okay for us to be doing this?" Ferguson asked, but Star was already taking hold of his cock in one hand and spreading her pussy lips apart with the other.

"I can't wait! I can't wait another second!" Star exclaimed, dropping herself onto his cock. Her body shuddered and winced, taking him in so quickly but she slid on to him with little resistance. For Ferguson the experience was amazing, she was so tight and hot and the pressure of her squeezing around his cock was incredible. Groaning out, Star leaned forward and laid over his stomach, putting her arms around his body to hold on to him. "It's... so filled up." She moaned, her hips slowly starting to rock against him.

Ferguson laid on the bed watching Star's blissful face as she continued to roll her hips against his cock. Her pussy squeezing in delight around his member as she moaned into his skin. He wanted to do more for her but Star seemed determined to do exactly what she wanted and it wasn't like Ferguson was very experienced in this to begin with. So he kept still as her body thrusted more, eventually pushing herself up to sit on his lap and bounce on top of him. "This is amazing! I can't believe sex feels this good! I should have been doing this all the time!"

"I'm really loving it too!" Ferguson agreed with her, Star smiling down at him ravenously as she continued to drop onto his cock harder and harder. "St-Star I'm going to-!" He couldn't get the words out before the constant movement of her body made him cum again. This time pressing up into her pussy as he did. Star let out a cry of pleasure as she felt him shoot inside of her. Hot cum coating the walls of her pussy and giving her some relief from the desire that was plaguing her.

"M-more..." Star moaned, her body shaking. "Still not enough... you can give me more, right?" Star asked him, nearly pleading with him for it. Ferguson was catching his breath as he rarely put himself through this much physical effort but considering what was being offered he nodded his head in full agreement. Smiling brightly to his consent, Star pulled herself off of his cock with a moan, crawling off the bed to get her wand. Waving it around with the practiced motions from before that eventually made it glow with that pink aura again.

"Uh, Star!?" Ferguson said, interrupting her before she could do the final part of the spell. "Can you just... tap me with it instead of hitting me this time?"

"Oh! Uh, sure, sure, I can do it softly. Watch." Being extra careful with him, Star used the wand and gave Ferguson's dick a small tap. The pink energy flying from the wand into his body and causing his cock to shoot up fully erect again. The sensation was so sudden it made him gasp and grab his chest and how quickly the blood flow in him moved. "Is that good!?"

"Sure... sure it was." Ferguson agreed, gasping as he wasn't sure how many more of those his heart could take. "Uh, if we're going to... y'know, do it some more, can we try a different position?" He asked and Star was curious but nodded her head in agreement. Moving back on the bed he gave Star room to crawl on, directing her to turn away from him and get on all fours. As she did Star spread her legs apart and looked at him from between her legs, giving him a direct view of her ass and pussy.

"Like this!?" Star asked eagerly, shaking her behind at him as if to lure him closer.

"That's perfect!" Ferguson agreed, climbing up behind her and putting his hands on her hips. Star reached back with her own hand and guided his cock into her pussy, groaning loudly when she felt him plunge into her again.

"Oh wow! This is... a good position! It's even deeper than before!" Star moaned, Ferguson thrusting into her from behind as she held herself up. Her body rocking forward as the mass of his own collided into her each time. He was doing his best not to slam into her with too much of his weight but the eagerness to fuck her was overwhelming. I didn't help his restraint that Star was moaning loud with each push inside of her pussy. "Sex is so good! I should have done this a long time ago!" Laying her head down on the bed, Star focused on keeping herself held up for him, her long blonde hair brushing off to the side to reveal her small pink wings. Fluttering with each push inside.

"I like how your wings flap when I go in." Ferguson said genuinely, pulling her into him and pushing in as deep as he could go.

"Oh my Glossaryk! Do that again!" Star cried out, Ferguson obliging as he pulled back and shoved into her hard once more. Star's fingers digging into the bed sheets as her muscles squeezed around him tightly. "I'm c-cumming again!"

"Can I keep going?" Ferguson asked, not stopping regardless of her answer as he continued to push into her over and over. Eventually letting out a moan as he also came inside of her, Star let out a high pitched squeal of mixed delight and shock feeling her pussy filled once more with hot fluid. Ferguson pushed himself in deep as he unloaded into her pussy and pulled back, his cum dripping out of her onto her thighs and bed sheets below as her body rolled over and collapsed on her side. Both breathing hard after their passionate love making.

"It's still... it's still tingling. I'm still horny but I'm tired." Star groaned.

"Do you wanna go again?" Ferguson asked excitedly and after a few moments Star nodded her head. Pulling herself by her hands to the edge of the bed she reached down to grab hold of her wand. Performing the motions with her arm again, although in a much lazier fashion, eventually causing the wand to glow pink once more. Star searched for Ferguson behind herself without looking and to help Ferg grabbed hold of her wrist to guide the wand to touch is cock. The sudden rush hit his body once more as his cock swelled fully erect.

"I can't get up." Star groaned, still laying on her side on the bed.

"That's okay, I don't mind laying down too." Ferguson said, moving behind her to lay sideways on the bed with her from behind. It was a little difficult as he took up much more space than she did but thankfully Star's smaller frame allowed them both to fit. Reaching down to her thighs Ferguson pulled Star's leg up and tried to guide his cock inside of her. Star's hand reached down and helped it find her pussy entrance, still more than wet and ready to accept him as he slid in easily.

"Nnngh! It's still so thick."

"It goes a lot easier now though. There's barely any resistance at all." Ferguson said, slowly pushing up into her as they both laid on their sides. Star let him keep her leg held up as he pushed inside of her. Moaning from the penetration but unable to move her body as enthusiastically as before after going through two orgasms. Still something about the slow pace of fucking this way felt good too. Different from before but still pleasurable.

"Heh heh heh... I could fall asleep like this." She said, smiling dreamily as she let out soft moans each time Ferguson pushed his hips up into her.

"I could do this every day! Sex with you is the best, Star."

"Mmm, I could do this every day too. I don't ever want to stop doing it. Why don't we do it all the time?" Star groaned in pleasure. Letting go of her leg, Ferguson's hand moved over Star's waist to hold her closer to him. Pulling her down against his lap so he could push up into her with that much more force. "Uuugh! It's filling me up again."

"I can't go slow anymore." Ferguson said, gasping as he began pushing faster into Star's pussy. Her body was tired but she still wanted to feel his cum inside of her again. To feel that pleasure of an orgasm. Letting her free hand slip down between her legs, Star began to massage her clit in circles with two of her fingers as Ferguson's pace grew faster. "Star, I'm gonna do it again."

"Uh huh! Go ahead, I want you to!" Star moaned, lifting her own leg up now as she rubbed her clit hard. Eyes closed tightly as she felt each heavy thrust up inside of her body until finally Ferguson couldn't hold it back any longer. Shooting his third and final hot load into her pussy as it mixed and overflowed with the previous orgasms she enjoyed. Star's thighs closed down around him as he pumped into her, body reacting harder than she expected as he came inside of her and suddenly pulled out, rolling on to his back on the bed. She could feel his cum slathered between her legs from their fun and it was a warm and rewarding feeling. Maybe it was the spell she had cast or maybe she was really growing to love sex, but she could still go for more.

"Hey Ferguson." Star said in a sultry voice, rolling over to look at him. "What do you say to a round four?"

About all he had to say was a loud snore as he had fallen asleep on the bed right after releasing inside of her. Star sat up suddenly looking him over. "Hey! Did you just cum in me and fall asleep! That's rude you know! You can't just pass out on a girl after filling her up!" She complained, shoving him with her hands. Though all that managed to do was cause his body to shake as he continued to snore next to her. Pouting with a grumble, Star sat there on the bed looking annoyed. "Well great, now what am I supposed to do to take care of this problem!?"

"Hey Marco, you here?" A new voice called out, Star turning her head to see the door open and a familiar face walk in. "Heh, just messing, I know no one's… home?" Janna said, having seemingly let herself into the house while she thought it was empty. That really wasn't a surprise considering her reputation. However there was the rare moment where Star saw a look of shock on the girl's face as she noticed Star naked on the bed along with Ferguson passed out beside her. "Uh… um… I uh… is this a bad time?" Janna fumbled her words, not really sure what to make of everything she was seeing. Though Star only had one thought seeing another person and feeling that hungry drive inside her begin to grow again.

"Hmm... well, beggars can't be choosers I suppose." Star said with a predatory smile as she stood up off the bed and her wand began to glow pink. "You'll keep me company until Marco gets back, won't you Janna?"
