Endurance

Black Wisp woke up to the feeling of a much larger stallion lying next to her, one that had apparently moved its' forelegs around her while she slept. While the changeling knew that ponies could consider it romantic, she frankly didn't care, and just enjoyed the warmth it provided.

Incidentally, she could feel the gentle hum of dreams coming from her 'prisoner' over her mental link - for a very loose definition of the word prisoner, anyway.

While she would have absolutely loved to spend the morning messing around with his dreams, she didn't even have the knowledge she needed to cast the spell, much less interact with his dreams. And so that split-second fantasy of hers was out the figurative window. Well, at least until she acquired said spell. Which would probably be never.

She snuggled further into the stallion, content to rest for most of the morning. After all, she had nothing important to do, and no responsibilities. The only thing she had to do was sort through all of the stallion's personal belongings... Which Wisp realized she could do lying down.

The changeling levitated his saddlebags over using her telekinesis, opening them with a thought and leaning it towards her.

The first thing she saw was a ration pack. While changelings were perfectly capable of eating and digesting normal food, and could even survive off of it alone for a while, there was no point in doing so while she could use them to feed her own source of energy. The second item she pulled out was... A magazine.

Wisp smiled.

She looked through the rest of the contents, finding nothing but a hygiene kit, more rations, a blanket, and a sharpening stone, before turning her attention back to the magazine. Wisp idly flipped through it out of boredom. Although she could count some of the more risqué pictures inside as being good, overall it was a bunch of standard crap.

"Where do they even make these things?" Wisp mumbled as she flipped to another page. "A drone could be more arousing than this, and they're barely smart enough to spell that, much less put it into practice."

"Wha-?" The stallion next to her slurred, awakening from his rest.

"Oh, you're awake." The changeling said, startling the stallion, who has unable to move much due to what she had hardwired into his mind last night.

"Y- You were real!" The unicorn blurted, panicking and attempting to move further away.

"Don't worry, you won't be able to move much." Wisp replied, moving even further into the stallion's unwilling embrace, and turning her head to look into his eyes, and levitating the magazine into view. "And what, do tell, is this?"

"A- a... Er... Wh-.... What?" The stallion stammered.

"Don't worry, I don't mind... Too much." She said, giggling. "However, I don't think you have very good taste. The stuff in here is pretty weak."

"Why am I hugging you?!" The unicorn shouted, his face turning a shade of red on top of his orange fur. "And why are you looking through my stuff?! You're a changeling! You can't do that!"

"Are you trying to make me cease?" Black Wisp asked, turning another page. "Because if you are, you are forgetting that I do not care."

The changeling mentally noted his attempt to use telekinesis to rip it out of her own, a shock spell to set it on fire, and even an incineration spell to destroy it. She felt her own mental commands reverberate through his mind, stopping each and every attempt at destroying it.

"Are you feeling frustrated this morning?" Wisp asked as his face flushed an even deeper shade of red. "Is something bothering you? Do you need me to... Relieve you of stress?"

"W- what did you do to my magic?" The stallion managed to ask. Wisp made a mental note to keep him flustered - it was far too cute to resist, especially when a mere day before he had been a blustering Royal Guard. The reversal of fortunes was rich.

"Oh, this and that." She cheekily replied. "Don't worry, I'm sure that it won't last forever."

"You!" The stallion said accusingly, before letting out a wordless groan of frustration.

"Speaking of which, what is THIS doing in here?" She asked, turning the magazine so he could see the full-page, highly-detailed... Drawing... Of Princess Celestia, who was in a very inviting pose.

There was no response from the stallion, and the moment Wisp looked back she could see why. The unicorn was speechless, with his mouth open and his face flushing a brilliant shade of red. In addition, she could feel his 'little stallion' starting to poke out.

To compound the thoughts she felt moving in his mind, Wisp darted her head forward and locked lips with him. The changeling enjoyed the sudden switch in his thoughts from mild lust and confusion to panic and horror. The stallion was unable, however, to resist her thanks to the mental locks she had put up.

After an enjoyably brief period of violating his mouth with her tongue, the changeling withdrew and gave the stallion a coy look of innocence, along with one of her winning smiles. The stallion's eyes were wide, and his mouth was still open in shock.

"Y-... You're crazy."  The unicorn stated after he finished gawking at her in shock.

"Am I?" The changeling asked, rolling over so her body was facing the stallion. She felt his member growing between them in response to his lust, and moved a hoof down to stroke it, tracing her chitin over the tip.

"Just s- stop!" The unicorn pleaded, panting. "Just let me go!"

"Hm..." The changeling pretended to ponder, before shaking her head and brushing some of her hair aside. "Nah."

She levitated the nearly-forgotten blanket out of the pack and unfolded it with her magic, laying it over the two of them in a manner that left only their heads uncovered. Wisp quickly changed that by going fully under the covers, moving lower and lower until her head was level with his length.

She gave the tip an experimental lick, and smirked at the sudden surge of lust into his emotions. The changeling began to gently tease the stallion, while lightly feeding on the lust that was practically dripping from him. The blanket still hid her from his eyes, which made it hard for the stallion to tell what she was going to do next.

Taking the next step, Wisp opened her mouth wider and put the flare into her mouth, lightly sucking on it. She ran her sharp teeth over him in a teasing manner, delighting in the shiver that went through his body. Wisp was thankful, however, that she didn't have the large fangs that most drones did. That would certainly put a stop to what she was doing.

After a short time of teasing the stallion and listening to his gasps and moans, Wisp decided it was time. The flare popped out of her mouth, and the changeling rolled the stallion on his back, pulling the covers off to reveal herself standing over him.

"Any words before I make you mine?" She purred.

The stallion below her blabbered something about not doing it, but Wisp was hardly listening. She slowly lowered herself onto his length, cooing in delight when the flare touched her moist folds, before pushing herself down onto his thick shaft. Inch by inch, it spread her tunnel open, stretching her out as it went.

Black Wisp was panting in pleasure when his medial ring finally touched her lips, and the changeling stopped. She would take the rest of his length eventually, but this was enough as it was. She used her hind legs to push herself up, the hard cock inside of her slowly withdrawing. When only the flare was left inside, she pushed down again, only stopping once she hit the medial ring.

The changeling took her time as she rode the stallion, enjoying the pleasure it was giving her. She placed her right foreleg on his chest for stability as she bobbed up and down, making sure to siphon some of the large amounts of lust the stallion under her thrall was putting out. As far as she had experienced, sex was always like this: It brought out the most filling of emotions, and weakened any resolve a being might have. Likewise, when she had wandered Equestria as part of her training, it was also her favorite pastime. It was the most pleasurable way - quite literally - to obtain her kind's food.

She pushed herself down harder, the medial ring of the stallion slipping inside and stretching Wisp to her limits. She continued to go down until the flare brushed against her cervix: Looking down, the changeling could see that she had, oh, only about two inches outside. She grinned at the stallion, her stallion, with a predatory smile. The unicorn was staring at her blankly, his mind mostly lost to the pleasure he was receiving.

Wisp could feel her moist tunnel clenching around his shaft. She pulled herself most of the way off of his member before shoving down again, gasping as his tool pushed into her. She put her left forehoof against her mouth, attempting to stifle her moans as she rode him. She failed.

Through her mental connection, she could feel his climax coming, and rode the stallion harder, wanting, no. needing him to finish. Her wet slit was stretched wide by his shaft, driving her onwards. With each downward thrust, Wisp could feel him growing closer, until he was right on the edge.

As she pushed down, an uncounted number of moments later, the changeling felt him flare inside of her. She held herself down on him as he climaxed, shivering in perverse delight as she felt more and more of his hot, thick seed push into her, filling her womb and what little space was left inside of her depths. She shuddered as her own climax arrived, washing over her and clearing her mind, leaving a dull - but pleasant - feeling that lingered on.

Panting, Black Wisp looked down on the stallion with half-lidded eyes, wanting nothing more but to keep riding him until he broke. But she could always do that later, save it for another time. The changeling collapsed onto the unicorn's chest, with his softening member still lodged inside of her, twitching as it put out a few last, small squirts of spunk.

She closed her eyes and nuzzled his chest, feeling some mild affection for the stallion - her stallion, at least until he was broken. She could always move on and find another one to sate her. In the absence of hope for her species, what better way to celebrate its' possible extinction?

And with that last thought, she drifted off to sleep.
