I'm not sure how the community here feels about Healslut fiction, but I tried my hand at one. It's not as explicitly sub/dommy as some of the stuff I've seen, but... enjoy? x3

"Ich bin da!"

The subtle thrum of the Valkyrie suit kicked in as Mercy took off, the engines in her elegantly designed wings carrying her far into the skies to meet her target. Up here, the wind tore at her face and buffeted her, but the slender woman had had a lot of practice in staying aloft by now, and the gale did not bother her as it once had. Resolved, Mercy gripped her staff and directed the beam at the figure above her, the blue power armor reflecting the bright sunlight with every movement.

"Clearing the area!"
Mercy's companion let loose a bright missile of pure energy that pushed down and erupted with concussive force, sending foes scrambling for cover below. Pharah laughed gleefully and followed up with a volley of rockets, and Mercy saw the fat grin on the Nubian woman's face as the rigors of combat sent her into blissful ecstasy. With the healer's caduceus staff sending a wave of energy through the other woman's powerful Raptora suit, the rockets rained down and cleared a solid path. Far below, the rest of the team pushed in, battle cries and confident taunts echoing up to the flying duo.

"Let's get on the payload," Mercy called, looking up to where Pharah was hovering, a series of rapid jets from the jump pack keeping them both aloft. Pharah looked down and smiled at her companion, but shook her head.
"No. Head them off. Flank and clear-- they'll never see it coming."

Mercy's brow furrowed, but she did not object. Presently, Pharah activated the jump pack and shot into the skies, and Mercy obeyed the unspoken command, her Valkyrie suit's power surging to allow the blonde woman to follow suit. Soon enough, they were far from the front lines, hovering along a cliff's edge until Pharah brought them down in a small alcove, out of sight. She waited until Mercy's heels touched the ground before dragging the healer forcefully against the wall, a strong arm across the blonde doctor's belly.

"They won't find us here." Pharah grinned and reached up to pull off her helmet, exposing her dark skin and black hair to the bright sunlight. The alcove was a dozen feet across, and a soft breeze crept through the warrior's hair. Otherwise, all was still. The din of combat was either too far off to be heard, or battle had yet to be rejoined. Mercy opened her mouth to speak, but Pharah put a gloved finger across the healer's lips.

"Quiet. They won't miss us yet. What is it you always say-- 'A moment to enjoy some peace and quiet'?"
Mercy nodded and smiled. She understood, and Pharah returned the smile as she clutched her helmet under her arm. But rather than remove her finger, the woman let it travel down to Mercy's jaw, then up to caress her ear. Goose bumps accompanied the cold metal tracing over her skin, and Pharah grinned as Mercy shuddered softly.

"These enemies are no match for us... the team won't miss us for a while yet. It's just you and me... and you know what I want, don't you?"

Mercy blinked, then nodded. A soft smile crept across her fine lips as she whispered: "Yes, of course. Allow me..."
She was about to kneel when Pharah's hand came to her forehead and stopped her. Mercy looked up questioningly, blue eyes meeting brown ones. A soft smirk curled the Egyptian's lips, and with a deft movement of her hand she pulled Mercy into a hard, hungry kiss. The blonde woman gasped against the lips and tongue seeking hers, but after a second she allowed herself to melt into the arms of the stronger woman, armor meeting armor with a soft clink as Pharah pressed herself closer to her healer.

"Good girl," Pharah murmured as their lips parted, Mercy's breath coming out as soft pants. "Turn around now." The healer obeyed, and she felt Pharah reach down to tug away the cloth covering the healer's backside. Then a strong hand pressed between her shoulder blades, forcing the doctor to bend forward, her arms bracing her against the raw cliff as Pharah knelt down and pushed the blonde's slender legs apart.

Slowly, fingers began to creep up along her inner thigh, caressing the skin through the fabric of the Valkyrie's undergarment. Though designed to withstand attack, the fabric was easily penetrated by a softer touch, and Mercy suddenly felt cool, fresh air waft against her leg as Pharah sliced a fine incision into the fabric, leaving the milky skin underneath intact. The sharp edge of the Raptora suit's glove parted Mercy's futuristic garb like so much pantyhose, and in seconds, her entire nether region was laid bare. She shivered with the sensation of the chill mountain air against her lower lips, already damp from Pharah's assertive, aggressive kiss, and heard the woman chuckle behind her.

"Eager, eager..." A soft hiss told Mercy that Pharah had dislodged the glove of her Raptora suit. Another, and the sound of metal on stone, and then Pharah's hands came up to slide underneath the ruined garment and squeeze Mercy's ass with demanding force. The Raptora suit buzzed softly as Pharah repositioned herself, sliding farther in between the pale, inviting cheeks which she slowly spread apart with her thumbs. Already, the scent of the healer's arousal was thick in the air, and the Egyptian woman amused herself with the sight the moisture glistening on the healer's cleanly shaven lips. Then, with one hand reaching up to keep Mercy well bent forward, the soldier dived in and pushed her tongue against her partner's sex.

The instant Mercy felt the tongue snake its way between her legs, she bit her lower lip and forced a moan back down her throat. Silence, secrecy-- they were hidden out of sight, but anyone walking by above would hear them, could peer down and see her bent over, submissively offering herself up. The wings of her suit twitched slightly as the healer arched her back, and despite her best efforts, a soft groan escaped her lips as she felt the tip of Pharah's tongue slide over her clit. Another noise, this time a gasp of pleasure, and Mercy began to panic, realizing how expertly the other woman was working her over. The tongue slid like a heat-seeking missile from the top of her lips past the sensitive nub and down to lap at the wellspring of her juices, before sliding back up and zeroing in on a slow and steady circular motion around the bead, which drove the healer wild. Desperately, she pressed two fingers against her teeth and bit down, hoping to stifle her groans as Pharah relentlessly attacked her slit.

Over and over, the Egyptian soldier pushed Mercy to the brink of orgasm, only to move away from her clit at the last second to suck and kiss the outer lips, down her thighs and rug her nose against the fragrant sex. All the while, Pharah's fingers worked over Mercy's cheeks, massaging and molding them, thumbs sliding down to spread the lips wide for her tongue. The soft, white skin and delicate pink pussy spread so willingly to her fingers, and Pharah began to understand why the male members of Overwatch were so keen on receiving Mercy's private consultations. After the third time of nearly bringing the Swiss beauty to climax, she moved one hand down and poised two fingers against the opening, which slid in without any resistance. Mercy gasped and whimpered, and Pharah barked a soft laugh.

"We ought to get back," she whispered, her fingers sliding out at a glacial pace, dragging the slick wetness along to the sound of Mercy's soft moans. "They'll be breaching the castle soon... wouldn't want to miss the entire party."
Slowly, Pharah pushed her fingers back inside the healer, observing the way the soft flesh molded and sunk down with the pressure. Mercy was panting down, still trying but failing to keep quiet. With another show of teasing effort, Pharah dragged her fingers back out and left them lingering at the wet lips, the touch just light enough that Mercy could feel the digits, felt them waiting, poised to grant her even more pleasure.

"Please," she muttered, and arched herself to try and capture the fingers inside her. But Pharah pulled them back, chuckling against the soft, white skin.
"Say it again."
"Please..!" Mercy heard the lustful whine in her voice, but could do nothing to stop it.
"Again." Pharah's voice, although muffled between the healer's legs, had a commanding tone, one tinged with sly amusement. Her fingers hovered against the opening, unmoving, taunting.

"Please, Fareeha..!"
"Mmh." Pharah smirked and digged her fingers back into the healer's supple body, curling the digits towards the G-spot and dragging slowly back, which made Mercy gasp with sudden, blissful sensation. The blonde doctor began to mewl softly and bump her hips back, and Pharah reached in, ducking beneath her own, pumping fingers to dig her tongue against the healer's clit. The full frontal assault lasted only a few seconds before the Egyptian felt Mercy shudder, the muffled cries belying a powerful orgasm rolling through her entire frame. Mercilessly, Pharah kept the pad of her tongue grinding against the sensitive nub, her fingers caught deep in the pulsing, clenching grip of Mercy's sex. And then, finally, the healer slumped, a soft sigh dripping from her lips.

Pharah pulled herself from the healer's incredible wetness and patted her on the ass, the smell and taste of her conquest still fresh and smeared liberally across her face. She picked up her gloves and began strapping them back on while Mercy got to her feet, reaching back to try and cover up the glaring hole in her garment. Despite the long, flowing cloth draped down from the back of the Valkyrie, Mercy knew that it was only too obvious to anyone who paid attention to her backside, and with the prospect of flying ahead of her, it would only take someone looking up to see her exposed, glistening slit. But Pharah merely grinned and put her helmet back on, the rocket launcher securely back in her hand. Mercy grasped her staff.

"Well, then... I think I hear the team engaging. Shall we?"
Mercy, legs trembling with the aftershocks of her orgasm, simply nodded.
"Good! We'll show them no mercy." Pharah looked down at Mercy's crotch, smirked, and shrugged. "Well... maybe a little Mercy."
The healer blushed.

And then they were off.
