[SUMMARY] Slipstream and Windblade meet on the battlefield once again. When their clashing leads them to be alone together, Slipstream finds refuge away from it all with Windblade.
Read this fic on AO3, or below the cut.
Blasts streamed across the darkened sky above the snowy landscape, creating an array of colors that brought artificiality to the mountains’ dull barrenness. Autobots and Decepticons, both diminished in numbers compared to their magnitude back on the war-torn Cybertron, clashing once again on the backdrop of Earth.
Naturally, that meant that Slipstream and her nemesis were also fighting each other. She held out her arms straight in front of herself, firing at Windblade with the null rays mounted on her arms. Windblade used her sword’s pink blade to deflect the blasts, quick as usual.
Too often their encounters ended with Windblade managing to take the upper hand from her at the last moment, snatching victory from her when it was just in reach. Anger coiled in her spinal strut as she remembered the latest disparaging remarks made by her superiors. Never was she worthy of their respect, perpetually beneath them with every failed mission validating their scorn.
This time she would not be defeated.
“Give up, Autobot. The Decepticons will soon have the AllSpark in our hands,” she spoke in her measured, authoritative voice.
“Not a chance, Decepticon,” Windblade gained on her and slashed at her with her sword, “I’ll do everything in my power to stop that from happening.”
Slipstream dodged the slashes. “So noble, aren’t you? But you’re just a puny little Autobot against the might of the Decepticons.”
Windblade whirled around Slipstream’s incoming kick, sending her another slash, “Is that why you can’t defeat me? Need the rest of the Decepticons’ strength just to take me down?”
Slipstream leaped back, aided by her heel thrusters. “You’ve just been lucky so far!” she hissed. Transforming into jet mode, she rammed straight into Windblade and took her clutching form into the air.
Windblade swung herself to get on top of her, fingers digging into her metal to get a grip and not be thrown off. But Slipstream would give no free flights today. She rolled in the air until she was completely upside down, forcing Windblade to hazardously dangle until she lost her grip and was swallowed up by the snowy abyss beneath them.
Slipstream descended and transformed back into bot mode on the ground. The sound of their comrades’ blasters echoed distantly, muffled by the weather. “Come out, Windblade,” she held her arms out ready, “admit defeat by my hands.”
“Not a chance.” A voice sounded behind her, but before she could whip around she was thrust onto the ground by Windblade’s annoying rogue fans.
A foot stepped on her back, as though assuming victory over her.
“This isn’t over!” Slipstream snarled, twisting around and shoving Windblade’s foot off of her. “Not until I say it is, with you at my feet.” She lacked the time to get to her feet, so she sat up and readied her null rays and—
Windblade’s sword had came down and cut through her null rays.
“No!” Slipstream, spurred on by rage, sprung to her feet and grabbed Windblade’s arms, charging into her. Her blue eyes shone clearly, unobstructed by the falling snow, and Slipstream saw them widen when she realized that the ground beneath them had vanished.
Windblade kicked out of her grip and swiftly transformed, but flew within the gorge they had fallen into. Slipstream transformed and trailed her, sending missiles her way. Her target dodged by ascending higher. The missiles flew past and struck a stony arch loaded with snow. Slipstream attempted to speed up to avoid being caught, but heavy snow descended upon her.
She was able to transform back into bot mode before getting buried, but the weight of the snow pinned her entire frame in place.
Another failed mission.
She wished she could harness the heat of her anger and use it to melt away the snow. How inglorious was this defeat: not dealt out by the hands of her enemy, but by nature! The captain of the seekers, waiting to be rescued by her seekers.
Soon, much sooner than she thought possible, she heard from without what sounded like digging and scooping through the snow.
“I’m here!” she called from within. Maybe one of her seekers had been tailing her? She had been too focused on Windblade to notice anything or anyone else. As evidenced by her sorry situation at present.
Dark fingers poked through the snow. Thrust, maybe? But she was surprised to look out and meet the gaze of Windblade!
“Yeah,” Windblade scooped more snow out, “I couldn’t get a signal out of this gorge. So I thought I’d spare you the possibility of your comrades just leaving you here.”
Slipstream hauled herself out and stood up with a scoff. “Generous. Like I’d need your help, Autobot.”
Windblade folded her arms. “Just because you’re embarrassed doesn’t mean I’m wrong.”
“Embarrassed?” Slipstream repeated with scorn. She was hot with rage, not embarrassment! She would be a fool to waste this opportunity Windblade had handed her on words, so she suddenly charged at her when she noticed that her sword was no longer drawn.
“Again?!” Windblade said, exasperation clear in her voice.
“As many times as it takes.” Slipstream shoved her against the nearby wall of the gorge. “Without my null rays, I can still take you down.”
Windblade dodged her incoming punch, ducking out of the way. Slipstream shoved her again before she could produce her sword. She fell, again, and plummeted into some cave. Slipstream followed her into it.
Windblade, recovering herself, took her detachable fans and threw them up at her. Descending into the cave, Slipstream kicked the projectiles out of her way and came down onto Windblade, knocking her to the ground.
“This ends now.” Slipstream glared down at her, hands resting on her pauldron-like shoulders.
“You’re right,” Windblade laid back against the cold ground. “It does.”
“Finally tired of your futile fighting?” Slipstream gave a smirk. But something about this felt peculiar. If she knew her nemesis like she thought she did, she wouldn’t just give up like this. Her fans couldn’t move on their own, right? She threw a cautious glance over her shoulder and saw them laying on the ground, unmoving.
Click.
Slipstream whipped her head back around to see that Windblade had, in the absence of her attention, successfully cuffed one of her hands. “What?! Unlock that this instant!” Slipstream barked down at her, yanking her hand from her grip.
“Not just yet.” Windblade brought her knees to her chest and kicked up, throwing Slipstream off of her. Instead of maintaining her distance, she grabbed Slipstream’s cuffed hand and brought it around her back to secure it to her other hand.
“Hey!” Slipstream jerked away from her, hands now cuffed behind her back. She quickly used her heel thrusters to get to higher ground and landed on a boulder that overlooked her opponent.
Windblade gave her that self-satisfied, infuriating smirk that Slipstream had grown familiar to as she looked up at her. “Looks like I win this round. You’re not getting out of those.”
Slipstream sat down on the edge of the boulder with her legs dangling off and watched Windblade recover her fans. She scoffed. “This is ridiculous.”
She could not admit defeat. It was easy to imagine the scolding her superiors would give her for letting an Autobot defeat her. But, she remembered, there were more than just the seekers present in this battle. Right now she was helping by distracting one of the Autobots.
Windblade looked up at her. Slipstream leaned back to hide her face from her view. Losing was not totally without benefits. Not with Windblade, at least. They had a private agreement between them, though rather loose on the frequency it was enacted, that when one of them lost that the other could…
Slipstream’s face was overcome with blush. If her superiors found out, then she would really be in for it! But they only ever did it when they were sure they were alone. Neither of them wanted to be found out by their comrades.
Windblade must have been thinking of their agreement to have thought to bring handcuffs with her to battle. And she, smart as she always is, was able to successfully capture her. The embarrassment brought on by being captured by an Autobot as captain of the seekers was immense.
Slipstream collected herself. No! This still wasn’t over. She looked down at Windblade and assumed a more comfortable and arrogant position where she sat. She projected her measured voice down to her, “I admit, it is cute that you thought of me, your nemesis, before coming into battle, Windblade. But such foresight won’t determine how this ends.”
Windblade crossed her arms, smirking. “Is that so?”
“It is,” Slipstream shot a glare down at her. She just had to think of what to do. With her hands bound behind her like this, it was impossible to transform. On top of that, she couldn’t shoot thanks to Windblade chopping off her null rays, not to mention how stupid of a position she would have to be in to try were it possible.
“Then let’s decide on the outcome.” Windblade suddenly shot up to her place on the boulder.
Slipstream, surprised at this sudden move, was unable to do anything when Windblade took hold of her and brought them both back down to lower ground. She fell flat on her rear with a thud. When she looked back up at Windblade who stood before her, the Stormfall sword was drawn and pointed at her. The moonlight that shone from the gap above silhouetted her frame.
The awesome picture in front of her left her slack-jawed and speechless. The blade emitted a soft pink glow.
Windblade brought the sword to rest upon her purple shoulder. “Have I won now?”
Slipstream’s gaze met the bright blue gaze that pinned her. “I suppose I can’t do much while like this,” she conceded before glancing down.
The flat of the sword pressed against her cheek. When she lifted her head the sword tip slid across her jawline then underneath her chin to lift it. Windblade cupped Slipstream’s burning face with her free hand and leaned down to her.
She lingered for a moment looking at her, not yet moving in for the kiss that Slipstream had grown to anticipate. “But this is right where I want you.”
Was it traitorous to lean into the praise of an enemy? The timbre of her voice, exuding a calmness Slipstream didn’t think she could receive anywhere else. Her superiors seemed unimportant, peripheral, now. The blaster shots outside became more like distant white noise than the sounds of a battle she was partaking in.
“So I’ve fallen into your trap, is that what’s happened?” Slipstream spoke while her cheek rested in Windblade’s hand.
“Not quite,” Windblade replied. “A ‘trap’ sounds nefarious, and this isn’t something nefarious.”
Noble nonsense. Of course she would say that. “Then stop your staring and kiss me already. I know that’s what you’re going to do.”
Windblade chuckled, brushing Slipstream’s warm cheek with her thumb. “I think you’re getting to know me really well, then.”
Slipstream parted her lips when Windblade brought her face down to meet hers, tilting her head slightly. Windblade was also warm, despite their chilly surroundings. When Windblade stood up to her full height, lips retreating from hers, Slipstream wanted to grab onto her to hold her in place. She remained with her.
In a languid manner, Windblade dragged the tip of her blade down Slipstream’s body. Its pressure was just enough to feel it slide across her metal but without seeking to inflict damage upon her frame. Slipstream couldn’t resist from leaning back regardless.
The energy sword’s soft pink glow in the dim light was all she could look at. She could so clearly feel the way the blade dragged across her metal, then to the glass of her cockpit, and then to her purple pelvic armor. The tip lingered right on her groin for a moment, as if waiting, then slid down her thigh.
She clenched her hands behind herself when her internal fans activated unbidden. Her gaze clung to the sword, as though she were mesmerized by it. The heat within her ached for the tender touch of her nemesis. But she could not disturb the silence.
The blade slid back to her groin, across her closed panel, then to her other thigh. Slipstream bit her lip. She looked up at Windblade whose gaze was on her groin, then it lifted to meet her red eyes. Windblade’s blue eyes glowed in the darkness, and were just as enrapturing themselves.
“You look so cute like that,” Windblade said, regarding her face.
Slipstream ducked her head, face overcome with blush. None of the Decepticons would ever dare to use language like that with her. Windblade looked down again to resume ghosting the blade across her. Slipstream could resist this teasing no longer.
Her panel opened with a click, revealing her valve.
“Pretty,” Windblade said, carefully spreading a lip with the tip of her sword. Slipstream was visibly wet with arousal.
Slipstream gritted her teeth. “Stop teasing me. Stick it in already!”
“Huh?” Windblade’s gaze jerked up to meet hers. “Slipstream, I wouldn’t—”
“What? I thought you were going to slide the sword into me!” her face overheated. There was no way Windblade could tease her like this and not deliver! Oh, what kind of Decepticon begged for something like this?!
“It’s an energy sword, so I worry about that prospect interacting with your systems,” Windblade explained.
Slipstream scoffed. “I could handle it.”
Windblade was silent for a moment, thoughtful. “Here’s an idea. If you can grind against it without issue, then—”
“Then let’s do that,” Slipstream got to her knees immediately, straddling the lowered sword. “After I overload, put your sword in me.” If she wasn’t wet enough now, she would be then.
Windblade was the one with blush upon her cheeks now, watching Slipstream grind against the flat of her sword. With her free hand she held Slipstream’s face so she would keep looking up at her. “Don’t be so quiet, I want to hear you.”
“It gets you wet hearing your nemesis moan for you, doesn’t it?”
Windblade leaned down to her face. “Do you think of me as your enemy every time we do this?”
“My nemesis,” Slipstream corrected.
Windblade smiled then captured her lips in a kiss.
Slipstream ground against the sword with more vigor, letting herself moan into Windblade’s mouth. The warmth of the blade felt good against her node and her lips.
Windblade held the back of Slipstream’s helm while they locked gazes with each other, “I see. You’re my nemesis too.”
Slipstream’s little node throbbed at those words, tender and intimate in their effect. She continued to eagerly grind herself against the blade, sliding against her own lubricant on it. Windblade dove her head down to kiss along her neck, earning more moans from her.
She was easily pushed into overload, her arousal inflamed by Windblade’s unrelenting affection. During any point of this she would have liked to grab onto her, but the handcuffs prevented this, reminding her who was in charge between them. Her hips rocked back and forth across the blade as overload surged through her systems. Windblade was still at her throat, kissing. Moans tumbled out of her, and Windblade could feel the vibrations against her lips.
Slipstream’s rocking hips stalled and her posture weakened. Windblade rose up and slid the sword out from between her, revealing the smear of lubricant Slipstream had left on it.
“Here, clean it up,” Windblade held the sword to Slipstream’s mouth expectantly.
Being without the liberty to use her hands, she could not manipulate the sword how she pleased. She could only angle herself in accordance to how Windblade held it. She opened her mouth and used her tongue to lave the sword while looking up at her.
After a time that satisfied Windblade, she said, “That’s good,” and withdrew the sword.
“At last.” Slipstream needed no instructions for the next part. She lay down on her back and spread her legs. Windblade followed suit by kneeling down between her legs. With her index and middle finger she spread Slipstream’s lips apart and carefully placed the tip of the sword between the spread fingers at her entrance. “Do it,” Slipstream’s eyes were glued to the tip touching her entrance.
“Eager are we? Alright, I’ll only push it in slowly. Don’t move.”
Gingerly and slowly, Windblade pushed the sword into Slipstream’s valve. It felt strange, being so thin and flat, but its sharpness provided an edge of tension. Slipstream had to remain still, or else it would cut her. Getting sent to the medbay from this would be worst than embarrassing, and she refused to imagine it.
Windblade’s eyes were focused on the task at hand. Each increment to the sword’s depth inside Slipstream felt indescribable. It was her nemesis doing this to her, at a time that they should be battling alongside their respective comrades and defeating each other. But they were fooling around instead. Slipstream liked to think that this was her own influence on Windblade. Selfishness and indulgence were Decepticon traits, right?
Throughout this she kept holding her internal fans in place, as if their spinning could unintentionally make her move too much while the blade was inside her. But they’d stutter to life every so often, working to dispel the heat within her.
“There,” Windblade said after a while, “This is as deep as it can go. Do you think you can remain still if I touch you?”
“Of course I can.” With difficulty, but she was going to make it possible. She needed Windblade to touch her, especially while under her mercy. The prospect was too hot not to indulge in.
Windblade kept her grip on the sword while she lowered her mouth to Slipstream’s node. Her tongue flitted across it to and fro. Slipstream had to resist the urge to buck into her warm mouth.
“K-keep going,” Slipstream urged her. She moaned under Windblade’s skilled tongue, clenching her fists underneath her as she fought the urge to rock her hips.
Already so aroused, it took little to make her overload again. Windblade licked her through the waves of pleasure that washed over her systems. Her valve throbbed against the blade inside. The danger only added to the depths of her overload.
Just as careful as she inserted it, Windblade slowly pulled the sword out of her valve. The blade was more slick with her lubricant now than it was before. She retracted the blade into the sword and set it aside so she could crawl atop her.
Slipstream threw her legs around Windblade’s waist, pulling her down. “Remove these cuffs.”
Windblade smirked. “Desperate to get your hands on me? I know what you’d try to do. But you should remember that I’m the one who won here.” She opened her panel and spread her glistening lips.
“Windblade…” Slipstream whined, unable to touch her with her hands.
Windblade positioned herself so that their valves met. She held Slipstream’s head and pressed their lips together in a kiss, capturing her moaning with her mouth. Her hips rocked against her, mashing their wet valves into each other and sliding across. Slipstream arched into her with desperation to feel all of her against her. Windblade knocked their nodes against each other, eliciting moaning from the both of them.
“Slipstream,” Windblade moaned into the crook of her neck.
Slipstream responded in kind, moaning.
“I think I’d prefer spending my cycles like this with you,” Windblade murmured .
“With me?” Slipstream’s voice was even quieter.
“Yeah,” Windblade’s valve felt so good against hers, “We connect well, don’t you think?”
They could not be in a more intimate position—tribbing while looking into each other’s eyes. It melted Slipstream. Overheated her systems. The thoughts of her superiors were so far away now, banished to the snowy mountaintops above and barred from this cave while she lay underneath her nemesis who loved her.
Windblade kissed her and continued rubbing her valve against hers as they overloaded together.
