Spike helps cure Starlight Glimmer's unbearable heat.

Starlight Glimmer was having a horrible day. Each shift of her hind legs, every insistent wink, and even the twitches of her dock felt like molten lead was being poured between her thighs. And it was getting worse. In short, she was in heat.

Just when she felt like she would snap at the thought of going through an entire week of Tartarus, her cries for relief were granted by the most unlikely of sources: Spike.

Fetishes: Estrus (heat), anatomically correct, hemipenes (double penis), inter-species, underage, first time, vaginal sex.

Sweet, Sweet Relief

“Why—” *Wink* “—won’t—” *Wink* “—it—” *Wink* *Wink* *Wink*

“Stop! Why won’t it stop?!” Starlight Glimmer shrieked in frustration, her voice echoing throughout the castle’s empty library. She thought that reading might have been enough to keep her mind off of her aroused state, but her rapidly winking clit seemed had other ideas. It unfolded and retracted each second, further kindling the fire deep within her nethers, and botched any concentration that she might otherwise have had.

With a snort of anger, Starlight gave up trying to read and threw her book across the room. Subsequently, she used her magic to spread her folds with an audible squish, allowing cool air to rush within her burning flesh. Fluids dribbled from between her parted labia, and pooled under her tail, the sticky mess no doubt staining the soft cushion she sat on. She sighed in relief. Sadly, that relief was temporary as the heat between her legs ignited with new intensity, making her whine as she felt her desire increase three-fold.

She leaned forward in her seat, causing her plot to stick out slightly, and waved her tail from side-to-side in a desperate attempt to fan herself off. It wasn’t helping, and it was only going to get worse from here. There was a whole week of estrus to look forward to, after all.

Starlight’s ears folded back in a mix of distress and frustration.

She needed a stallion.

Now.

But how? She didn’t know any of the stallions in town, and even if she did, she didn’t want to get pregnant! The only stallion she knew was Sunburst, but he was all the way back in the Crystal Empire. Besides, she doubted he liked her more than a friend, anyways.

It was times like this where she missed her old society. Obligatory heat services were the best idea she ever had! No pony had to worry about suffering, because only in an unequal society would one sex suffer more than another! It was perfect!

She threw her head back and groaned loudly. Who could possibly help her with—

“Hey Glimmer, are you alright? I thought I heard you scream!” Spike’s worried voice came from behind her, causing her to freeze in place. Her plot was still sticking up, tail raised high to the sky; revealing everything to anybody who bothered to look. Which meant Spike had full view of her glistening nethers.

However, instead of turning around and pretending she was fine like a normal pony, she leaned even further, flagging her tail ever higher. Showing off her aroused flesh to the young dragon. ‘What are you doing?!’ Her mind screamed at her.

“I don’t know, Spike, do I look fine?” She asked sarcastically, glancing over her shoulder at the young dragon, and swishing her tail back and forth in obvious need.

Spike’s eyes widened at the sight, unable to look away from Starlight’s rear. Her lavender slit was absolutely soaked, with fluids dribbling down the seam of her labia and dripping onto the cushion just beneath. Each unfolding of her rapidly winking clit flicked a small spurt of lubricant into the air, the needy gesture causing a stir in his own loins, one of his two tips peeking out from his genital slit, causing him to blush with embarrassment.

She locked eyes with him, the desperation conveyed through the look alone caused his heart to clench with sympathy. There was no doubt in his mind that she was in heat, and he knew from how often Twilight complained about it how bad it could be. And as he looked under her raised tail, he knew it was pretty bad. She was a friend, and friends helped friends in need, right?

“I’ll help you if you want me to… I promise I won’t tell Twilight,” Spike offered, staring into her suddenly wide eyes with a smile. He may have had a crush on Rarity, but Glimmer was so much more. She was always nice to him, treating him as an equal, and was really fun to hang out with as well! There was also the fact that she was a super villain at one point, which if he were being honest was kind of cool. Her flank was also incredibly sexy…

Her eyes lit up in gratitude. “You will? Oh thank you, Spike! You have no idea how bad this feels!”

“You’re a very good friend to me, Glimmer, and I can’t stand watching you suffer.” He broke eye contact, twiddling his thumbs in nervousness. “I-I don’t know if I can please you, but I’ll try my best.”

“At this point, I think you’d have to try to not please me. It’s not like my vagina is very picky at the moment, “ she said with a chuckle, trying to ignore the insistent winking under her tail, as well as the small amount of guilt building up in the back of her mind. ‘He’s only a teenager. You’re taking advantage of him. Twilight will find out.’ Her mind insisted.

However, she’s had plenty of practice at justifying herself, so all it took was three simple rebuttals; ‘He offered. He’s going to love it! He promised not to tell Twilight.’

Spike glanced at her muscular flank, before looking into her eyes again. “O-okay. So, uh, I’ve never actually done anything like this before. I just stick them into you, right?”

She was about to nod, but then his wording caught up with her. “Wait, ‘them’? What are you talking about?

Spike nervously twiddled his claws. “Uh, my penises? That’s like, basic stuff.”

Starlight Glimmer swiveled on her seat, and looked at him with wide eyes. “You have two penises?! That’s an actual thing? I didn’t know that.”

“Yeah. Twilight told me all dragons do. It was an… awkward conversation to say the least. I guess that wouldn’t be common knowledge.”

Starlight mulled that over for a second, before deciding to just go with it. It was strange, but very interesting as well. She was still extremely aroused, but she waited this long; she could wait another minute in order to sate her curiosity. “But how do you, you know, orgasm? Does it come out of one or both?”

His face grew red. “O-only one at a time. I’ve tried j-jerking both of them at the same time, and while it felt good, only one of them actually climaxed. I’m not sure why…”

“As long as they work, they’ll do.” The frequency between winks increased by twenty percent, and the burning grew even more uncomfortable. She shifted her butt, consequently rubbing her clit across the soft fabric of her seat. “So, do you know where there’s a good, isolated room nearby we could use?”

“Well, there is a private reading room just down the—”

She stood up and cut him off, “Lead the way!”

“Alright, follow me!” Spike turned and started off, Starlight followed closely behind. Her tail was hiked up as far as it could go, and she was leaking all over the ground. She followed him all the way to a curtain, and they both made it inside.

There was a single circular table made of crystal just barely raised off the ground, and about six very soft looking cushions. No books were in here, but there was a single lit candle on the wall softly illuminating the small room.

Starlight Glimmer didn’t waste any time in jumping up on the table, and right onto her stomach, her hind legs and butt hanging off the edge. She looked behind her, and smirked at Spike’s wide eyed expression. “Like what you see, Spike?” She teased him, waving her tail in his face.

His mouth went dry at seeing her bottom half dangling off the tabletop, her thighs shifting ever so slightly as she got comfortable. Her ass rippled with each movement she made, and the fur around her plump vulva gleamed with lubricant. Heck, even the anus tucked under her dock was glistening with fluids, no doubt the result of her shuffling around while sitting. And it was all for him.

Spike’s hemipenes rapidly grew from the arousing site, the twin organs thin at the base and ending with a rough bulbous mass full of nerve endings. He walked right up to Starlight’s rear and grasped her upper thighs with his claws, feeling the powerful muscles tense up. A single claw from his right limb brushed against her flushed vulva, and Starlight’s tail hiked even further up.

In curiosity, he squeezed one of her lips between his thumb and index claw, the squishy folds easily compressing between his digits, resulting in a twitch from one of her hind legs. He snaked his left hand across her thighs, and rested his palm against her entire pussy, the moist heat radiating into one of his only areas that lack scales. Her clit unfolded against him rapidly, each wet kiss smearing lube against his hand. “Wow, you feel really weird!

Her ears flicked in annoyance, and she snapped, “Weird?! It’s not weird, it’s perfectly normal! Just as equal as every other mare!”

Spike felt her tense against him, and her tail flicked hard against his chin. He wasn’t sure where this attitude came from, but he needed to reassure her quickly! “Sorry! I-I didn’t mean it like that! I’ve just never felt a mares’ privates before, I wasn’t calling you weird or anything!”

She deflated, mushing her vulva against his palm in an attempt to alleviate some heat, and maybe to calm herself down. “Sorry, I guess I’m just a bit tense. Just hurry up with your examination. I know this is your first time and you’re curious, but I really do need it badly.”

Deciding to give her what she wanted, he moved his now wet claws to the sides of her flank and stepped onto the cushion in front of him. Then he pushed his hips forward, and gasped as one of his dicks squished against Starlight’s winking clit, the soft flesh caressing him with every lewd beckon, while the other parted the opening to her unbelievably warm slit just above.

“I-I’m really going to do this. I’m going to have sex!” Spike uttered in awe, the implications hitting him all at once as he rubbed his dragon cocks along the base of Starlight’s slick cunt, gripping her thighs even tighter.

The feel of her flesh unfolding against Spike’s dick was driving her mad, and she needed more. “F-fuck me, please!” She begged, her tail swishing against Spike’s belly in anticipation.

Spike was at full mast at this point, and pushed upwards, one of his dicks just barely spreading the lips of her moist entrance with his bulbous tip. Starlight panted hard at that, and Spike just let out a shuttering breath. He then leaned against her back, trapping her twitching dock against his belly, and thrust forward, her outer folds giving way with relative ease.

“O-oh jeez, you’re really, really warm, Glimmer.” Spike stuttered out as he sunk into the tight, squeezing flesh of her cunt. He was practically swallowed by her softness, and her clit winked harder than ever against his other penis, the wet nub sloppily kissing his sensitive tip in the only way it could.

She let out a pleased sigh as she felt Spike penetrate her depths, however her dock was being bent upwards, and it was started to cramp. “Could you hold my tail to the side? It kind of hurts,” She told him, her ears folded back in discomfort.

“O-of course, Starlight!” Spike readily agreed, and wrapped his claws around the base of her dock, moving it aside and relieving the pressure in her tail bone. She pushed back in delight, which caused his thumb to squish against her anus, the donut-shaped muscle clenching at the contact. In response, he rubbed the outer ring in circles, liking how the taut flesh spasmed in sync with each flex of her dock.

Starlight had never felt such a strange feeling before. His claws fit perfectly around her dock, and one of his digits tickled her butthole in such a way that it sent tingles up her tail. A grin spread across a face, and she looked into his dilated pupils. “Wow, now that feels strange. You like my ass, Spike? Well, maybe after you cure my heat, I’ll let you slip into that tight ring. Do you think you’d like that?” She felt him twitch within her, and his grip around her tail increased. “I’ll take that as a yes.”

He pulled out, her walls gripping him tightly, the friction causing them both to gasp in delight. His dick rested against her slick outer lips for a couple seconds, and then he wrapped one of his claws around her lower waist and grabbed hold of her small teats, cupping her breasts to her immense glee. And with one hand around her tail, and one hand around her small mounds, he proceeded to sink deep, deep inside the unicorn, her slick passage offering little resistance.

“Ah, that feels so good!” Starlight moaned, her left leg twitching as she was filled once more. He slowly humped back and forth, and she pushed her rear back in earnest, biting her bottom lip as she shut her eyes in delight.

He started a steady pace, pushing deeply inside until his tip softly brushed up against her cervix, and then pulled out until he was barely held between the seams of her labia. He snorted as he gripped her breasts even tighter, thrusting deeper and harder into her eager cunny. Each time their hips collided, he yanked her tail, causing Starlight to whinny in surprise, her anus twitching against his thumb as she squeezed his dick tightly in response.

Spike could hardly believe what was happening, even as he felt Starlight’s flesh clenching around him in earnest. He was fucking a mare. His dick was inside somepony! It felt incredible, and the pressure within his gut was very close to bursting.

“F-fuck me!” Starlight demanded, her voice hitching each time she was spread. “Cure my heat, please! I’m so close!” She gyrated her hips against his own, feeling her climax approaching as his shaft rubbed against her insides oh-so-wonderfully. Each thrust resulted in his other penis jabbing her clit, and that contributed to her pleasure more than anything else.

Faster his small body went, until he finally felt the pressure release, and his cock exploded with sensation. “S-Starlight!” He almost growed, holding onto her lower waist tighter than ever before as ropes of cum splattered against Starlight’s cervix.

Spike’s semen was practically an inferno, the scorching hot liquid almost feeling like it would boil her insides. “Oh, Celestia, that burns!” She yelped out, a bit louder than she meant to. However, it still felt bucking amazing, almost like a balm that simultaneously cooled her heat and burned her insides. Which combined with his second dick hitting her clit, caused her mind to go blank, and her vision to swim with stars, her pleasure reaching its peak in a crescendo of sensation.

She breathed hard and fast as her cunt rapidly squeezed and clenched around Spike’s cock, pulling his tip right against her cervix, and causing his next few loads to fill her womb with liquid fire.

He pumped his seed deep within her rapidly orgasming pussy, the undulating passage swallowing his shaft whole as it milked him for everything he had. The soft walls were holding him in a vice grip, rippling around him as Starlight moaned with immense relief.

“Oh thank you spike, I needed this so badly!” Starlight said, her body shaking in delight as orgasmic waves traveled through her. Spike’s claws dug into her breasts as he held onto her barrel, just soft enough that he didn’t hurt her, but hard enough to hold himself steady. The embrace felt kind of nice, actually, and perfectly complimented the heat that cooled her nethers from the inside out.

Spike just held himself deep within her involuntarily clenching snatch as he came, jerking his hips slightly in order to feel her soft insides slide against his tip. The frequency between each of his spurts decreased, until with one final gyration of his hips, his orgasm ended.

Starlight’s powerful muscles held him in place as Spike's hemipenis softened, the rough surface of his tip feeling wonderful within her contracting walls. The pressure as she gripped him was immense, until with a wet plop he slipped out of her, and she felt a rush of his fluids spilling between her vulva. Her walls closed up tightly in reflex as her pussy was vacated, and her lips quivered at the empty feeling.

Spike released his hold on her slightly sore dock and breasts, sliding his claws across her flank before giving them a small squeeze.

“You did great, Spike,” Starlight breathed out as she looked back, her fur glistening with sweat, and beamed as she noticed Spike’s expression. His serpentine tongue hung out of his maw, a goofy smile plastered across his face. His two members visibly retracted into a little slit just between his legs, and once they were gone she kind of thought it looked like he was female.

“Really? It wasn’t just because you were in heat, I-I was actually good?” He asked, feeling slightly self-conscious as his arousal died down, letting go of her firm butt in the process.

Carefully crawling down from the table, she landed on the ground with a hard clip-clop, her tail still raised high to the sky as she felt Spike’s still burning spunk drool out of her snatch. She sidled up to him and looked into his slitted eyes with a patient smile. “Really. You were pretty good for your first time! The double penis thing was a bit weird at first, but the way your second one slammed against my clit felt amazing, so I got used to it pretty fast. I also really like how you pulled my tail and squeezed my teats. Really nice.”

“I’m just glad I could help! Your insides felt awesome, but the fact that I was able to help a good friend like you was an even better feeling!” Spike stated with conviction, puffing up his chest.

She giggled at his bravado, but a sudden thought caused her laughter to cut off. What does this mean for them? She didn’t know if she liked him romantically, but even if she did it couldn’t work out. Her breath hitched; what if he had a crush on her? That would explain why he was so adamant about helping her. “Spike?” She started, feeling embarrassed for the first time today. “How do you feel about me?”

Spike grinned, his ear fins perking up as he ticked off with his claws. “Oh that’s easy! You’re fun to hang out with, you’re easy to talk to, you’re really nice, you’re the only adult who doesn’t treat me like a child, and uh,” he paused for a moment, his right claw scratching his chin in thought, and her fluids still gleamed on his claws. On a whim, his long tongue snaked out and licked his digits, Starlight’s tangy fluids electrifying his taste buds. He smacked his lips, the aftertaste akin to sapphires. “You also taste pretty good.”

Starlight found that a lot hotter than she expected, and she couldn’t help but wonder how that tongue would feel inside her. Her tail hiked up, and a single wink squeezed some more fluids out of her slit. “I’m glad you think that about me, but I meant, um, romantically, “ she said with an anxious grin, trying to ignore her lewd thoughts as she looked straight into his suddenly wide eyes.

He started sputtering. “I mean, you’re really pretty, and, uh, what we did was pretty fun, but, um, maybe?” He took a deep breath and calmed himself. “I kind of j-jerk off to the thought of you, if that counts?” 'Oh stars, was he trying to arouse me again?’ She thought as her clit gave two hard winks.

“Well, not necessarily. But back up; do you really clop to me? You find me that attractive? What about Rarity?”

He groaned into his claws. “How does everypony know about that?! Well, to be honest, I haven’t thought of Rarity that much lately. She’s beautiful and graceful, but compared to you she’s kind of, um, dull.” His eyes widened as he realized what he said. “D-don’t tell Rarity I called her dull!”

“It’s fine, Spike, I wouldn’t dream of ratting you out. Especially considering how much you helped me out.” He visibly relaxed. “However, you do realize that if you do have feelings for me, we can’t be together, right? Twilight would flip, among other reasons.”

“I-I understand,” Spike said as his entire body sagged. “But, could we at least just have sex sometimes? Maybe?” He asked, a slight sliver of hope in his eyes.

She wanted to nip this in the bud, but against her better judgement, the thought appealed to her. “Alright, -” Spike perked up immediately with a huge grin, and fist pumped “- but we have to be sneaky! And under no circumstances can we act like we screw each other when other ponies are around. Agreed?”

“Yes Ma’am!” He saluted, which caused her to giggle at the ridiculous gesture.

“Good. Now I just need to clean up, I’m dripping absolutely everywhere!” She said while lifting a hind leg, a mix of Spike’s and her own fluids squeezing out of her slightly parted folds. With a flash of her horn, all the fluids that covered them, as well as the floor and table in both this room and the other, vanished. As if the stains never existed. Which was exactly what happened. “Heh, time magic sure does have its mundane uses.”

“Aww, are we done already?” Spike whined.

That confused her. “But of course. It’s not like you’ll be ready for a few hours, so we might as well just call it quits.”

He tilted his head. “Why would I not be ready? I usually am able to orgasm twice in a row, so I can go for at least one more round!” His tongue flicked out, and he smacked his lips. “Besides, the taste of your fluids is getting stronger by the second. That means you’re still aroused, right?”

She clenched her thighs together in need, the thought that he seemed able to cum more than once in a small time scale opened up many possibilities. It was also pretty interesting that he could taste her through the air. She grinned. “You and I are going to have a wonderful time.”
