Twilight sat in her old bedroom, furiously rubbing her slit. She had gone into heat two days ago, and nothing here was giving her any substantial amount of relief. Sure, grinding against a particularly thick hardback book felt good, but it did little to assuage the heat she felt in her nethers. Her magic was near useless, too. Every time she tried to form a magical dildo to fuck herself with, she’d lose concentration after a few thrusts and become even hornier than before. Her bed sheets were soaked through with her juices, but they’d been like that for the past couple of days.
Her mother was out for the week, visiting some old friend of hers all the way in Manehatten. Shining was still in the Crystal Empire, leaving her alone with her father. She had no idea what he was up to, but she was certain that he knew she was in heat.
Twilight looked around her room, searching for anything that she could use to sate her lust. Nothing in particular stood out, making her throw her head back into the pillows. Her wings throbbed beneath her, but they’d been doing that all day. She was so pent up from not cumming, and she had spent most of the day simply trying to get off. Nothing worked for her, and part of her begged for her to run out into the streets and take the first stallion she could find. Twilight toyed with the fantasy in her mind for a bit, but she knew that she’d never do that. It wasn’t fitting for a princess.
Her nethers burned with desire for cock, but she’d left all of her toys back home. Her heat cycle usually came a week or two later, but for some reason it had come earlier than she’d anticipated. Twilight relaxed and brought her sopping wet hoof up to her lips. Her slit dripped with her arousal and seeped into her tail as she licked her hoof clean. She thought about going down into the kitchen to try and find something fun to rut herself with, but she knew her mother wouldn’t like it if she used her precious kitchen to get off.
As her pussy leaked more of her arousal, Twilight thought back to what her father had said the last time she was here. “If you ever need help or if you’re in trouble, don’t hesitate to ask me,” Twilight whispered to herself, reciting her father’s words perfectly. “What if... what if I asked him for help? Maybe just this once?” She had to do something about her condition, otherwise she surely was going to go crazy.
Her heart racing, she slid from her bed and trotted down the hall. The moonlight outside cast a pale blue light, giving her just enough light to not bump into anything. She turned the corner and paused, shuddering as she felt more of her arousal drip down her inner thighs. Twilight knew that what she was about to propose was extremely naughty, but her lust-driven mind could think of no other option. Besides, who better to get fucked by than somepony who had unconditionally loved and cared for her ever since she was born?
Steeling her resolve, Twilight stepped forward until she stood outside her father’s office. She raised a hoof and pushed the door open, her hind legs trembling. Flicking her tail up, Twilight put a rather alluring sway in her step as she walked inside. She spotted him reading a book at the other side of the room, his chair facing away from her. Locking her eyes on the back of her father’s chair, Twilight stalked towards her prey, making sure her hoofsteps were loud enough to let Night Light know she was there.
As she neared him, she heard him close his book. She stepped up to his side and nuzzled him, lingering longer than a daughter should. Her breaths came in short pants and her ears were flicked back. Twilight felt Night Light grow tense, but he relaxed a moment later. He nuzzled her back, then scratched her ear with a hoof, just how she liked it.
Twilight snuck a look down at his crotch, but was let down when Night Light moved the book to cover himself up. She knew that he could smell her desire, for it was a rather pungent smell that hung in the air akin to a thick fog. She nuzzled him again and sat down beside him.
“You remember how you said that if I ever needed help, I should come to you?” Twilight asked softly, her voice soft but husky. Night Light nodded silently. “Well... I need your help right now, Daddy.” She slid herself in front of him, feeling a small twinge of disappointment in her heart as she watched him cross his legs, hiding his good bits from her view. Twilight whimpered and looked up into his eyes, silently pleading for which she so desired.
“I... This isn’t right, T-Twilight...” Night Light stammered. “I know what I said, but you’re in heat! What would happen if you got pregnant?”
Twilight rolled her eyes and smiled slyly. “That’d never happen, Daddy. I cast a spell on myself when my heat cycle began for that very reason. I’m pretty certain that it lasts for my whole cycle, and it’s worked for me in the past, so...” She looked up at him with pleading eyes. “Please, Daddy... I’m so horny it hurts...”
Night Light sighed and relaxed. He smiled softly and ran a hoof through his daughter’s mane. “If you promise to never tell anyone, I...” Twilight’s eyes went wide at her father’s words. Her heart raced within her chest and she felt a fresh trickle of her arousal slip out of her onto the carpet. “I suppose I could help you find some relief.” He set the book aside and uncrossed his legs to reveal his cock, already standing at half-mast.
Twilight licked her lips, and after a nod from her father telling her to go ahead, she gently pushed her father’s hind legs apart. Twilight smiled and nuzzled his balls, then kissed and licked each of them, his musky scent dancing within her nostrils. His smell sent a small shudder down her back, pushing her to get more. She licked her way up his shaft until she got to the tip. Popping it in her mouth, she let off a soft moan and let it slide all the way to the back of her mouth. Twilight bobbed her head back and forth until she had him twitching beneath her.
She pulled his cock from her mouth and stood up. Her mouth was full of his taste, and she absolutely loved it. Twilight swallowed what little precum she had in her mouth, and even though she desired to swallow his seed, she had a much greater need that she needed taken care of.
Twilight shot a lustful grin at her father as she watched him get up from the chair, his dick bobbing up and down beneath her. He motioned for her to bend over one of the arms of the chair, so that’s what she did. Laying on her stomach, her front half lay in the seat of the chair while her ass and hind legs dangled off the edge. She wiggled her butt at him and flicked her tail to the side.
She felt her heart beat faster and faster as she watched him step up to her. He leaned down and took a large whiff of her scent, then licked her slit from her clitoris all the way up to her rear opening. Twilight lit her horn and toyed with her labia, small tingles of pleasure running up and down her hind legs. “This is from thinking about you rutting me, Daddy,” she moaned as she looked over her shoulder.
“Yeah? You smell so sweet, Twilight...” He slapped her ass, eliciting a soft moan from his daughter. “And you’re soaking wet, too! You should have come to me earlier...”
“Just fuck me already, Daddy!” Twilight thrust her hips back as she felt his cock land between her butt cheeks. “Please, I need to feel you inside me!” She whimpered again.
Night Light smiled down at her as he lined himself up with her entrance. Twilight smiled back and lit her horn, spreading her labia for him. She stretched her left lip first then moved to her right lip, tugging it aside so that her father could see inside of her. His cock twitched and leaked more of his precum, mixing with her arousal to slip down her legs. “You ready, Twilight?”
Twilight nodded fervently, and before she knew it, pure bliss spread throughout her as her father slid into her. She groaned and bucked her hips backwards, forcing another few inches inside of her. Twilight’s pussy clamped down on her father’s cock as it tried to keep it inside her. She wiggled her hips as he sunk his length further into her. Twilight let loose a soft grunt as she felt his medial ring bump up against her opening. She felt him pause, but she looked over her shoulder and nodded, too horny to talk.
Thankfully her message got across. As he applied more pressure to push his medial ring inside her, Twilight lit her horn and pulled her lips apart for him, then grunted as it popped inside her.
Night light paused again. “You need a minute, dear?”
“No!” Twilight gasped beneath him. “Keep going!” He needed no further coaxing from her as he continued to go deeper. Twilight bucked her hips back and felt their groins meet. She looked behind her and realized that she had taken her father’s entire length. That sight alone sent another shudder down her spine. “Fuck me, Daddy! Fuck me so hard I’ll be tripping over my hooves for a week!” She pushed a hoof underneath her and started rubbing her clitoris in circles, pushing herself to greater heights.
Twilight felt Night Light pull back, leaving her with the worst of feelings when one was in heat: emptiness. Even though it was only for a moment, Twilight whimpered and wiggled her hips, praying that he’d start fucking her like she needed. Her wish was granted soon enough, though. Night Light grabbed her by the hips and shoved himself back inside of her, eliciting a moan of approval from between her lips.
Twilight closed her eyes and bit down on her hoof as her father started fucking her. This was so much better than any other toy she’d ever used in her life. The warmth from his cock, the feeling of his balls slapping against her clitoris, it all piled up and pushed her to heights she would never have achieved back in her bedroom.
“I’m so close, Twi...” Night Light grunted, pistoning in and out of her like a fucking machine. “You want me to pull out, or—”
“Cum inside me, Daddy!” Twilight moaned, her pussy clamping down on his shaft over and over, desperately milking him for his precious seed. She was so close to cumming too, so she played with her clitoris faster and applied more pressure on it. Little bursts of pleasure ran up and down her legs as she neared her peak. “Cum for me, Daddy! Fill me up with your cum!” she yelled, her voice muffled by her hoof.
“You’re so beautiful, Twilight...” Night Light murmured as he too neared his peak. He leaned over and laid on top of Twilight, propping himself up with his front hooves. “You know Daddy loves you... never forget that!” And with a grunt, he slammed himself all the way inside of his daughter and slipped over the edge.
His words were just what Twilight needed to hear. His weight on top of her, pinning her to the chair, made her feel so helpless beneath him. She loved that feeling and bucked against him, his balls twitching against her clitoris. Twilight felt Night Light’s cock flare deep inside of her, then it began filling her with his seed. Her pussy milked him for everything he had, and she knew he was more than happy to give it to her.
She felt a mixture of their cum slip past the tight seal that his flare made to drip down her legs and onto the chair. Twilight bucked her hips back as his warmth filled her velvety pussy, then pushed up into her father’s chest only to be pushed back down. Wondering what he was doing, all thoughts were purged from her mind when she felt his lips wrap around one of her ears. He nibbled on it for a few seconds then switched to the other one as they came together.
As both of their orgasms finally died away, Night Light collapsed on top of her, the two of them panting heavily. “I love you... so, so much, Daddy...” Twilight whispered.
“Trust me, it was... my pleasure, dear.” Night Light picked himself up off of his daughter and pulled his softening cock from her pussy. “Feel any better?”
Twilight cherished the warmth that his seed provided her. “Mhm... a lot better, thanks to you.” She nuzzled him then let loose a small yawn.
“Getting tired, kiddo?”
“Yeah, kinda...” Twilight kissed him on the cheek, then turned to leave.
“Heh, alright then. Lemme know if you need anymore ‘help’, okay?” Night Light asked with a wink.
“Oh, trust me, you’ll be the first to know!” Twilight chuckled and made her way from the room. Her pussy trickled a mixture of their cum down her legs, but she didn’t care. Her mind felt fuzzy from cumming so hard, and even though she wanted to simply fall onto her bed and fall asleep, part of her wanted to double check the spell book she had used concerning anti-pregnancy spells.
Walking into her room, Twilight trotted over to her desk, her pussy still tingling. She flipped to the appropriate page, then scanned through the paragraphs until she found the right one.
“Anti-pregnancy spell, version one point one,” she whispered to herself. Twilight skipped over the technical details that concerned performing the spells, then started reading again. “This spell is highly effective and has a one hundred perfect success rate when used properly. When in heat, one must cast this spell every twelve hours—”
Twilight’s heart stopped beating in her chest as she stared at those words in the page. As worry filled her, she continued reading. “Or else the spell will wear off and become ineffective...”
Twilight sat back in shock, her eyes glazing over. She looked down at her leaking pussy, her right hind leg twitching like it usually did when she was a nervous wreck. Her father’s cum seeped out of her, forming a pool of their cum beneath her.
“Oh, fuck me...”
