'Tough Love'
Her heated little breaths came in sync with her downward motions onto his lap, the small feline seated comfortably upon the sitting canid. A shudder with every push, and a squirming sensation sent shivers along her legs, wriggling around his body. He pulled his head back slightly to slide his nose up against her own, and pushed it toward the bridge of her face, nuzzling affectionately. For a moment, she closed her eyes, forgetting where they were--in the engine room--and why they were there--because she needed the stress of command fucked out of her.
A quick little chuckle from his throat woke her out of the momentary haze. Her relaxation and enjoyment of the moment hummed as another wet, easy push up inside her sent another wriggle down her loins and tail. Her brows furrowed, and yet her panting mouth somehow gasped out words.
"Wh..what do you think y-you're doing..?"
He lifted her up slightly again, keeping the motions he was told to maintain. With one hand underneath her toned ass, he held her and moved her up and down his shaft. He dropped her back down with another distinguished mewl from her open mouth telling him nothing was wrong.
"Hrmn? Helping you unwind...I mean, you brought me here-"
"No. The..." she stammered, "Affection? Q-quit nuzzling me like... like..." She continued to sputter, once again losing her focus as his familiar, black-skinned cock found its way back up into her insides, nudging away at some tender fuse inside her mind. A singe of pleasure coursed through her belly and down her spine and tail, grasped in his large hand.
"Like what? Like you like me?" he teased, wearing a playful smirk.
She frowned, as much as she could with a slightly open, panting mouth, scowling mid-pleasure at him "I'm n..not into you!" she huffed madly. Her cheeks flushed, despite her truth. He was handsome, she'd admit, though only to herself in the back of her mind...but romantically? No. They bickered too often and had far too many differences to follow that path. However, this comfortable agreement to collaborate on sating their needs together in secret was the one thing she had no control over how much she liked; her body knew what it needed.
"You're holding me awfully close..." he chuckled, still nuzzling her face, his beath rolling against her forehead. He couldn't help it, teasing her was just too much fun.
Her will to quip back vanished as her body betrayed her. Quivers, shivers and all her small motions as she was man-handled upon his lap, gave him all the proof he needed. The blue and white-furred ass was sat back down on his thighs, her little legs apart and around his middle, giving him ample room to fit himself up inside. He wasn't some hung, breeding stock; she didn't want that kind of thing. That was for 'Princess Slut Puppy'. She had a surging ache that arose now and again, and it was his shape instead that did it for her. The slightly thicker mid-section, the length fit her comfortably full, and perhaps most of all, his willingness to keep quiet about it all. She couldn't deny or hide that she liked how he slung it to her, but...that smug, arrogant, smooth-talking stupid face of his wouldn't get to hear that, no sir.
"You're...s-so fucking lucky that I needed this." she barked out, finishing as he sat her back down on his pride, pushing her slick walls apart as it went up to the hilt. Her toes curled, her feet against his back. Biting her lip and trying to keep her eyes open to maintain some kind of control only worked against her, as it only showed how much she didn't have.
"Oh I know." he sighed, clearly enjoying both her body and the teasing he gave her. This wasn't one-sided, after all. There was no denying how attractive she was, especially to him. He admired her for plenty of other reasons though, and knew he was lucky that she needed someone who could keep a secret. Maybe she just didn't want to be viewed as subservient to anyone, maintaining that facade of control at all times. He'd always been a kind of people-person, eager to please, ready to help, and if that now required him to fuck the stress out of his tightly-wound friend then by gods, he wouldn't need to be told twice. "You brought me down here after all. The engine hall? You banking on the noise down here to drown out your moans?" he smirked, tilting his head and one large ear slightly to the side.
Vikna was red in the face, despite her blue coat. She stammered, but it was unclear if it was because she was trying to get the words, or if the next downward thrust her body took pushed his cock into her warmth at just the right angle. It pushed the air out of her lungs and she clung again to his body. Leaning into it, her muzzle planted in on his neck and lined up his mouth with her ear. Now amplified, his huffing breath joined the list of things she secretly liked about his love-making. It was rough, coarse, and scruffy like his mange. There was something about her refined, educated upbringing that demanded an equally refined mate. As so, there was something incredibly rousing to her senses that she chose to indulge in that instead, with a mangy hybrid canid in the back engine room of a starship, who filled her out just right, with his dirty paws grabbing her ass and tail as if she were a plaything to him.
A tinge inside her loins fired up. Thinking about all that, at a time like this, sent a firm swell through her lap, clasping up around his girth as it hugged its way into her. She bit into his neck as she sometimes did, and he could sense her ribbed, slick walls buckle inwards around him. He grunted, eyes slightly aflutter, as the noise tickled her ear. Absolutely sure he couldn't see her face, she let her eyes roll back, brows up, and felt that fuse light up inside.
"H-hooh, atta girl..." he chipped, knowing she couldn't talk back. This wasn't their first rodeo; her high-stress levels made for pretty frequent de-stressing, and he knew the signals of her impending orgasms. He also knew he was ordered not to stop unless explicitly told to do so. Easier said than done. It wasn't easy sometimes, to hold on...the first few times almost ended the whole arrangement because he'd finished first, and that wasn't going to happen. Though sitting, Nytro angled his hips as best he could upwards into her, and let go of her tush as it sat firmly upon his thighs. He ground himself up in there, stirring his dark, hard muscle into her pink lips as they hugged immensely wet against his cock base.
"Hhh..nh, y-you!! FF-fucking..!" she sputtered. He knew that motion set her off like crazy. Her heartbeat pounded, breaths rapidly accelerating against his neck as that fuse inside her loins burned wildly down. There was no avoiding her peak now. Through gritted fangs, Vikna dragged her claws along his back. She kept them trimmed almost for this reason alone; Nytro had told her it was difficult to explain claw marks down his shoulderblades if she intended to keep it a secret. She readied herself for the first finish, undulating her lap point-blank against his own, when she felt his large, commanding paws on her hips.
"Sshhh..just let me--" he sighed with a heavy groan. 
He drew her back up, feeling a crazy amount of resistance from her aching, needy lips that seemed to almost 'suck' at his spire. Before she could even think of a protest, panicking at the thought of her losing her peak when so close and so needed, he dropped her back down. Her soft mound nicely squished with a slight give as it landed on his loins, her ass pressed by his hands pushing down from their grip on her sides. A roaring fire rolled through her inner walls. She dug in and pushed just as hard as he did, her lower body suddenly surging in rolling bucks, grinding around his buried cock. A loud, lustful mewl escaped her open throat, the feeling of a climax  perfectly coupled with a deep, primal thrust.
The refined, lady-like commander cut off the yelp burying her mouth into the scruffy, dark male's neck. Her nostrils flared hot, heavy huffs of air across the back of his head and ear as she muffled out a wild mix of moaning, grunting and whines. The inner rolling muscles and closing, warm walls around his swallowed cock almost pushed him right off. Nytro almost lost it all,  eyes unfocused and being pulled so near his end by her insides tugging and sliding all around him that he had to try and laugh it off.
"Hh-hah..haha, wh-what was -that-?" he panted, regaining himself somewhat.
Her face was an absolute mess when he saw it. Hair all over, ruffled cheek fur, her eyes were one-half some mix of anger at the fact that he acted like he could do whatever he wanted with her, and one-half liked that he did. She pursed her frown, still shivering with light rolling aftershocks, squirming still sat upon his dick. 
"Hff.. if you ever...nh...I am not y-your..." she sputtered, pausing, kind of half-hoping he'd just quip back with some snarky remark.
Instead, he just smiled with that same smug smirk, though now with more ruffled fur patches and a bit messier hair, and gripped the underside of her soft rump, raising her up. Any other thought in her head went out the window, the feeling of sudden emptiness in her pussy making her instinctively gasp, only to groan out as he put her back in her place. Sat down onto his cock again, the feline squirmed a bit, sitting herself upright. She latched her paws now onto his chest, and for once, smirked back at him with a huff.
"You're good at following orders." she stuck a tongue out. It was probably the nicest thing she'd said all day, but he knew the inner meaning. A bite of the air towards her face and he purred.
"I assume that means the part about not stopping until told to do so?" he mused.
Vikna wiggled her rump against his lap, feeling his sizable malehood still aching with a dull pulse, her heartbeat pounded up into her throat again. "Not until we're both de-stressed and ready to resume duties." she quipped, a short nod that Nytro responded to with one of his own, pulling her close and slowly back up again...
