On Strong Desires

On Strong Desires.

Izzy Moonbow was a curious girl. Ever since she could remember, she wanted to know everything. Why was the sky blue? Why was the grass green? How did the chocolate chip cookies appear in the cookie jar every week?

Her parents had always encouraged her to ask and learn. Her grades at school had always been great because of her curious nature; not the best, mind you, since she always forgot to do homework, but at least she aced her exams. Still, her teachers seemed equally pleased with her every time she asked to clarify a subject and dig deeper into the pits of knowledge.

There was just one thing everyone always avoided to properly explain. Something that the adults always seemed hesitant and uncomfortable to talk about. Even just bringing up the subject was met with dismissals. But that only made Izzy keep insisting. Why were they concealing this information? Was it too complex or did they not trust Izzy with it?

Her teachers told her to ask her parents, and her parents told her that she was too young.

Years passed, and Izzy’s curiosity about sex only grew stronger. She only knew what it was called because her classmates talked about it in hushed tones. They were every bit as curious as Izzy, so she would always join them whenever they speculated. And when one of them brought a naughty magazine to school, they had their very first answers to exactly what sex entailed.

And it only raised more questions.

Unfortunately, when Izzy suggested they try it out, her friends gave her odd looks, and little by little they stopped talking about it… At least, they stopped talking about it with her. Izzy tried to get more magazines of the like, but no one would sell her or lend her one. Her inquiries started giving her a negative stigma within her hometown.

Once an avid student, now a strange kid. Izzy felt betrayed. Her pursuit of knowledge had always met smiles and encouragement, but now it only gave her a negative tag and alienation.

That is why, when she was old enough, she left. She had always been hesitant about it, scared of what lay beyond, but she couldn’t stay. If she wanted to learn about everything, about sex, she’d have to go to a place where she could find the answers. It didn’t matter where that could be, it didn’t matter if she had to go to Tartarus itself!

Some time later, she met a bubbly earth pony named Sunny Starscout. Although their initial meeting had been rocky, and Izzy had ended up almost being imprisoned for espionage, infiltration and many other crimes she had definitely not commited, she and Sunny had become good friends.

Sunny was really friendly and brave and admittedly cute. Izzy liked her pink mane and tail, her orange coat that turned a beautiful white at the hooves. She liked her green eyes and how they shone like bright turquoises under the sun. Sunny was also very physical, playfully whipping her tail at her, or bumping her rear with hers. As their adventure to save Equestria took them to many and various places, Izzy found herself liking Sunny in ways she had never felt. She always caught herself staring at Sunny’s shapely flanks and toned legs. She always tried to sneak glances to Sunny’s bright eyes and softly rounded muzzle.

Izzy wanted to know why this was happening to her, why she was feeling all these feelings. But she didn’t dare tell Sunny about it. She appreciated her friend, and she was fond of her many quips and quirks. She didn’t want to lose her like she had lost her friends all those years ago. So she stayed silent.

A few weeks into their adventure, they had managed to get a very cheap room at an inn in Seamare Shores. The city was one of the largest in Equestria, the kingdom’s trade hub. They had spent most of the day just browsing the market that extended for miles through the wide streets and plazas. They walked and talked, they bought souvenirs and discussed their plans.

By the end of the day, Izzy’s legs hurt so much she let herself fall on the bed.

“Whew,” Sunny said, setting her saddlebags next to the door. “I haven’t walked this much in my life.” She leaned her neck to the side and Izzy heard it pop. “I think we should go to sleep.”

Izzy only groaned as a response. She barely registered the words as her eyes slowly closed.

Her dream, as always, was pretty wild. She was levitating a large piano over her head while riding a changeling on the sea. Her quest for the enchanted treasure had taken her to Tartarus, where the blue and purple fires sang a song of lollipops while surrounding her. Izzy could feel the heat in her fur, but it wasn’t painful. It was more like being wrapped in a thick blanket on a summer day.

One of the fires sneaked between her hind legs, heating up her thighs and tail and-

She woke up with a silent gasp, feeling her body so hot it was almost unbearable. Looking down, she noticed she was wrapped in a thin blanket. She didn’t remember tucking herself in. Stiffing a groan, she levitated the blanket off. The cold night air immediately bit at her coat, but she endured it. Cold was better than heat.

But even though her sweaty body was cooling down, there was a spot between her legs that was still very warm. Izzy sat up and leaned over, spreading her hind legs to see if there was something wrong. The only thing she could see under the moonlight was a dark stain on the mattress.

Izzy breathed out, feeling her breath hot against her nose. She reached out with a hoof to touch her crotch and see what was going on. She gasped loudly, surprised at how incredibly sensitive it was. She looked to her side and saw Sunny’s back; the mare was sleeping soundly on her own bed. Good.

Reached over again, she carefully placed her hoof on her marehood and bit her lip to suppress another gasp. It was hot and damp. She pressed a little, and a spike of pleasure shot through her spine. She moaned, and immediately covered her mouth with her free hoof. She looked at Sunny again, who was still sleeping.

Another slight press, another spike of pleasure, another moan. Izzy kept looking at Sunny, just in case her friend woke up. She wouldn’t like her to think her a freak. Izzy moved her hoof a little, sliding it over her marehood. It felt so good. Why did it feel so good? She knew her crotch was sensitive, but not like this. Every motion sent shivers down her body, and she could barely control her moans and gasps.

And suddenly, she found herself not only looking at Sunny’s back, but straight of staring. Her friend had such a delicate figure, and her unbraided main flowed down nicely. Izzy didn’t increase her pace for fear of being unable to control herself, but she did not stop either. Why was looking at her friend giving her an extra level of pleasure? Was it because she had feelings for her? Izzy wanted to know.

So, making an effort to stop touching herself, Izzy quietly rolled on her bed and carefully got off. Her hooves were treacherously loud on the wooden floor, thundering in her ears as she made her way right next to Sunny’s bed. With a gulp so loud it felt like an explosion, Izzy activated her magic and carefully levitated Sunny’s blanked, ever so slowly uncovering the rest of her friend’s body.

She wasn’t looking at anything she hadn’t seen before. But somehow, this simple act of taking the blanket away felt both wrong and so, oh so right. Izzy sat down on her haunches and took her hoof back to her crotch, drawing small circles on her pussy. She was so close to Sunny’s shapely butt, she could almost smell her.

Feeling brave, with her heart beating so fast in her chest, Izzy carefully levitated Sunny’s tail. She wanted to, nay, she needed to see what hid behind. For weeks she had been wondering what it would look like, if it would be any similar to her own, if it smelled similar… If it tasted similar…

“So you finally dared.”

Izzy froze, painful cold washing over her body. She slowly turned her head to look at Sunny, and saw her looking back. She tried to come up with an excuse, a way to get herself out of this mess, but there was no denying what she had been doing, not with her hoof on her crotch and her magic still levitating some strands of Sunny’s tail.

“I was wondering when you’d do something like this,” Sunny said with a low voice. “Or if you’d do it at all.”

“I…” Izzy felt her mouth dry. “I’m so sorry! I didn’t- I wasn’t… I’m sorry!”

Sunny chuckled softly. “It’s ok, Izzy... “ She rolled her body over and rested her head on her left hoof. “I’m only mad at the fact you took so long.”

“I…” Izzy repeated. “What?”

“I noticed how you look at me,” Sunny said. “And I started looking at you the same way.”

Izzy moved her mouth silently for a while. “I… what?”

Sunny snickered. “You’re really cute, Izzy. But, you know, I would rather you’d started off with a declaration, instead of…” she lowered her eyes towards Izzy’s hoof, which was frozen on her aching crotch. “But I won’t complain… I’ll just ask you a little favor. You know, to make up for this little stunt of yours.”

Izzy nodded slowly. “I don’t know what came over me. I’m sorry. I’ll do anything to make it up to you.”

“I’m counting on it,” Sunny replied, then slowly sat up on her bed, never taking her eyes off of Izzy. “Are you familiar with the term ‘giving head’?” When Izzy shook her head, Sunny giggled. “Then find out,” she said as she spread her hind legs.

Looking down, Izzy felt her heart flutter at the idea of finally seeing Sunny’s pussy. Except that there wasn’t a pussy there. Izzy only recognized the growing protuberance from her memories of the naughty magazine from so long ago. It was a dick, she remembered, slowly coming out from its sheath of a darker shade. Beneath were what she assumed to be a pair of balls, hidden behind Sunny’s pink tail.

But why was it there? Sunny was a girl, wasn’t she? Or had Izzy just assumed her to be a mare because of her body and voice?

“I am a girl,” Sunny said, as if she had read Izzy’s mind. Izzy looked up at her and found her smiling. “Only I’m a very special kinda girl.”

Izzy had to agree. She had read and reread her anatomy books from school. Definitely not because she liked the simplistic illustrations of colts and fillies’ private bits. Only colts were supposed to have dicks, the books claimed. But there she was, one of the most beautiful mares she had ever seen, sporting an ever hardening dick.

“Go ahead,” Sunny said with a nod. “Satisfy your curiosity, Izzy. Do whatever you want with it..”

Those words were like keys to the chains that had been holding Izzy back. She breathed in as she returned her gaze down to Sunny’s crotch. She gasped, surprised to see the dick standing at full attention. It was… She wasn’t sure why, but she knew it was rather large. As long as her foreleg but not nearly as thick. The flat head was decorated with little bumps all around, leaking a strange transparent liquid in small droplets from its hole.

Izzy leaned in and gave the head a sniff. It was a thick aroma, earthy, pungent, moist, but not at all disgusting. Her crotch itched with more urgency, so she resumed her movements with her hoof, estimulating it as she gave a tentative lick to Sunny’s dick, spooning the liquid with her tongue.

She couldn’t begin to describe the taste. It was completely different from the liquid she produced in her pussy. But it wasn’t bad at all. There just was too little of it, though. If it worked in any way similar to her pussy, then it should be able to produce a large amount of the same liquid. And Izzy wanted it; she wanted to taste all Sunny had to give.

So, without thinking and just following her instincts, she opened her mouth around Sunny’s dickhead. Sunny moaned softly, and it was all Izzy needed to feel encouraged to continue. She made her way down, taking more dick into her waiting mouth. Soon enough, the dick touched the entrance of her throat. She gagged, but didn’t retrieve her head. There was something about having a dick in her mouth that she just… loved. Why? It was getting uncomfortable feeling it poke at her throat, but instead of backing out, she pushed herself down, doing her best to relax her throat muscles to allow the large dick invade it.

It was getting painful, and yet she continued. Izzy wanted all of Sunny, and she was going to get it.

Her lips met an obstacle on her journey down. Opening her eyes -when had she closed them?- she saw she had reached the medial ring. She tried to open her mouth wider, but no matter how much she tried, she just couldn’t. It was with a defeated sigh through her nose that she lifted her head, dislodging the dick from her throat.

Another moan from Sunny made her shiver. Or was it her own ministrations in her pussy? Izzy decided to find out, and as soon as the back of Sunny’s dick head reached her teeth, she pushed down again, swiftly getting to the medial ring again. Another moan, another shiver. Yes, she loved hearing Sunny moan, so she repeated the process again, and again, and again.

The taste was getting stronger as she kept bobbing her head, and she found herself liking it, actually liking it. She wanted more of it, so, like she would a lollipop, Izzy began sucking whenever she lifted her head. Her reward was immediate in the form of louder moans and more of that liquid. And her own pleasure was building up. Her hoof was drenched in her own pussy juice, and she knew she was close to releasing it all.

That’s when Sunny, with a loud moan, grabbed her head and forced her down, past her medial ring and all the way to the sheath. Izzy groaned at the sudden intrusion and the pain of having something so big so deep in her esophagus. Not soon after, though, she felt how Sunny’s dick flared, stretching her throat and completely blocking her air flow.

Izzy was overwhelmed. The smell of Sunny’s crotch, the taste of her dick, the discomfort and the pain and the pleasure. And when Sunny’s dick pulsed and sent a powerful torrent of that liquid almost directly to her stomach, it sent her over the edge, and she felt her pussy convulse and spray her juices all over the floor.

But it wasn’t just one squirt what Sunny offered. A second followed soon after, then a third and a fourth. With how much the dick pulsed in her throat, Izzy felt like she was indeed swallowing a very large amount of Sunny’s liquid. But how much more was there? She already felt full by the time of the eighth and last spurt. For some reason, despite the incredible amount of pleasure she was feeling, Izzy felt disappointed that she hadn’t been able to actually taste it.

Sunny released her, and Izzy immediately lifted her head, getting the dick out of her as fast as she could. She gasped and breathed deeply, finally tasting the air, and began coughing.

“Oh, crap, I’m so sorry, Izzy!” Sunny said as she placed her hooves on Izzy’s shoulders. “It just felt so good I couldn’t control myself! I didn’t hurt you, did I?”

Izzy took a good ten seconds to calm down after her coughing fit. Taking deep breaths, Izzy looked straight at Izzy’s eyes. Her crotch was still itching, and she knew, not because she had read it, but because her instincts screamed it at her, what she wanted.

“Mount me,” she whispered with a hoarse voice.

Then, without waiting for a response, she stood up and turned around, lifting her tail and allowing Sunny to have a full view of her drenched, aching, winking marehood. “I need you,” she said, and her hindlegs began giving little steps on their own. She couldn’t control them, nor did she want to. She didn’t know what she was doing, what she was asking Sunny to do, but she didn’t care. Her body was screaming, pleading for her to be mounted.

So, when Sunny stood up and stepped behind her, she instinctively waved her flank and fanned it with her tail. What made her do that, she didn’t know, but it seemed to work, only not in the way she expected.

Sunny dove in and buried her snout into Izzy’s snatch. Izzy let out a throaty moan as she felt Sunny’s tongue sneak inside her, going in and moving at random. Izzy had never had anything inside her pussy, so she had not been expecting something as tiny as Sunny’s tongue to feel so incredibly good.

Izzy gave little kicks with her hindlegs as pleasure overtook her. It was incredible, feeling Sunny’s tongue slither inside, licking her juices straight from the source. Izzy was lost in bliss, feeling her second climax building closer by the second, moaning and wheezing loudly.

Then, Sunny stopped.

The sudden lack of stimulation was almost painful. She looked back, intent of asking why Sunny had stopped, to beg her to continue. But her complaints died in her throat when Sunny gave a little jump and placed her forehooves on her flanks. She wasn’t a stranger to carrying heavy stuff, but for some reason, the added weight of Sunny’s body sent a strong spike of pleasure throughout Izzy’s body.

Sunny pulled her back, and Izzy complied, feeling a bit more weight being deposited on her back. She had been so lost in the new sensation that she failed to notice Sunny’s mouth was right beside her ear until Sunny spoke.

“You don’t know how much I want this,” Sunny whispered into Izzy’s ear. “I’ve been dreaming of mounting you ever since I met you.”

Izzy felt chills running up and down her body. She was about to reply, but then she felt Sunny’s dick rubbing her pussy, and she could only groan at the pleasure. She shuddered when Sunny moved back a bit and pressed the tip of her dick onto her waiting marehood.

“You’re beautiful,” Sunny said as she pressed her dick against Izzy’s pussy. “I, nng, I can’t believe I’m finally-” she cut herself off as her dick finally popped inside. She moaned while Izzy gave out a little shout at the intrusion.

Being penetrated was everything Izzy needed to reach her second climax, and she felt her own pussy close down and hug Sunny’s dick tight as her juices sprayed Sunny’s legs. She worried Sunny would be disgusted by this, but her worries disappeared when Sunny pulled her back, getting half her dick inside her in one thrust.

Izzy half screamed half moaned, but Sunny didn’t give her time to adjust and kept pushing her dick inside until the medial ring stopped her progress. Izzy found the sensation to be incredibly confusing. On one hoof, it was painful having something so big so deep inside her, but on the other hoof, it felt just so friggin’ good! She just couldn’t do anything more than moan with her tongue lolling out, dripping spit on the floor, and simply take it.

Sunny pulled back just a little and thrust again, sending a wave of pleasure all through Izzy’s body. She repeated the motion again, but thrusting a bit harder. Despite her foggy mind, Izzy realized that Sunny’s movements felt frustrated. Somehow, Izzy knew what it was, so she bent her forelegs and lowered her upper body, sticking her butt just a bit higher, and spreading her hind legs a bit more.

That did it, and with another powerful thrust, Sunny’s medial ring made her way inside along with the rest of her dick. Izzy howled in ecstasy, feeling so, so full. Once again, Sunny didn’t let her rest a single second, and immediately began pounding her hard. Their hips made loud, wet slapping sounds every time Sunny hilted herself inside Izzy.

Amazingly, despite having thought she could not feel any more pleasure than this, Izzy let out a long loud moan the moment Sunny bit her nape. It was so much, just too much, and Izzy felt her pussy contract violently around Sunny’s dick right before she, once again, reached her climax.

Sunny groaned at this and picked up the pace, making Izzy’s climax last longer than she thought possible. Izzy let her head fall limp, held only by Sunny’s teeth. Sunny hugged her closed as she kept going in and out of her.

Just how much longer could Izzy experience this overwhelming pleasure? The answer came in the form of Sunny’s thrusts getting erratic, and after a while, with one last powerful thrust and a loud whiny, Sunny unloaded her juices right into Izzy’s womb. Feeling the flaring head inside her pussy was not painful, unlike having it in her throat, so Izzy reached a new peak of pleasure, especially when Sunny shot her loads inside her.

They stood there in relative silence, except for their dragged out moans, as Sunny shot rope after rope. For a moment, Izzy thought they would be there forever, with Sunny lodged deep inside her, filling her up with that warm, sticky juice of hers. And she didn’t mind the idea.

But, all great things had to end, and with Sunny’s dick softening, she stepped back and away from Izzy. Now, being emptied like that was almost as much of a shock as being filled, so Izzy immediately fell to the floor. Her legs would not obey her any longer. It was with a sigh of odd satisfaction that she felt Sunny’s thick juices leaking out of her.

“That,” Sunny said, completely out of breath. “That was… so good…”

Izzy could only hum an agreement as her vision became blurry. She faintly felt Sunny lift her up and carry her to her bed. Then, as if it couldn’t get any better, Sunny laid down right beside her, on the same bed. This closeness, somehow, felt even better. She snuggled against Sunny as tiredness overtook her.

“I’m so happy I met you,” was the last thing Izzy heard from Sunny before she drifted off to sleep.

She agreed wholeheartedly.
