It was a dark and cold Halloween night at the Overwatch headquarters. Nearly every member of the international organization had shown up for the annual Halloween bash, and while dressing for the occasion certainly wasn’t mandatory, plenty of men and women had shown up in costume, ready to party away the usual stresses and worries of maintaining order in a chaotic world into the latest hours of the night. Most of the party was concentrated in the common area at the ground floor, where people gathered to socialize and participate in the seasonal festivities, but two notable individuals were conspicuously absent.

Several floors above, Mercy sat atop the commander's desk clad head to toe, except for her tiny shorts, in her witch's costume. The shorts lay discarded at the center of the office floor, tossed away carelessly in their frenzied haste to get down to business. Commander Jack Morrison stood firmly planted between her spread legs, the pants of his own costume lowered down to his ankles, as he drove into the moaning Overwatch medic. The flaps of her witch's dress were flipped upward and off to the side, which along with her missing shorts allowed her boss and superior officer complete access to her well-shaven and incredibly moistened pussy. The wet slapping of flesh against flesh filled the office room as they fucked with all the furious passion of two tipsy colleagues on the verge of being discovered in the middle of their scandalous tryst at any moment.

Of course, such a discovery would hardly be a surprise to anyone within the Overwatch team. Commander Morrison and Mercy were anything but an exclusive item, rather two adults in their prime who enjoyed the fruits of each other's bodies, and the insatiable libido of the svelte blonde doctor was the organization's worst kept secret. Indeed, by this point there was hardly a single virile male within Overwatch that Mercy hadn't burned through and come back to on several occasions whenever the mood struck her. Yet the doctor did have her favorites, and thus Mercy was in heaven that Halloween night as she was pounded into a blithering, writhing mess by one of the team's most skilled and well-endowed cocks. In her mind, there was no better way to get the night's festivities started.

"Yes, yes!" screamed Mercy heedlessly, her legs coiling around Jack's waist and crossing at her ankles, locking him in and encouraging him to go deeper. She tilted her head back, exposing her neck flushed red with heat, and the pointed hat atop her blonde head shifted askew, nearly ready to fall off. "Keep fucking me, you brute!"

Jack smiled behind his half-assed Halloween makeup. While the commander was more known by his subordinates as a stern, no-nonsense leader, he still enjoyed participating in the costumed revelry. However, he lacked the talent for the more convincing outfits, and from his poorly placed fuzzy fake eyebrows and scribbled brown makeup, the wolfman costume had initially been a huge dud. Still, Mercy seemed more than eager to indulge in the roleplay as they fucked like bunnies, and so he played along. "You've been a naughty witch, little girl. I'll have to teach you a lesson for trying to cast your vile spells on me."

Mercy ceased her moaning long enough to bite her bottom lip, but a deep thrust into her sodden pussy made her squeal aloud. "Oh no! What are you -- ah! -- going to -- mmhm! -- do to me?" she asked amid pleasured gasps.

He leaned in closer, his lips brushing against her ear as she panted and moaned into his. "Why, I'm going to fuck your brains out, of course." With a firm grasp on her hips, Jack yanked her forward, shifting her rear even closer to the edge of the desk and allowing himself a better angle of penetration into her deliciously tight pussy. Mercy threw her head back and screamed toward the ceiling, her witch hat finally toppling off to allow her blonde mane to flutter to the rhythm of Jack's thrusts. "What kind of witch dresses like such a slut? I bet you go around entrancing beasts just so they'll pin you down and have their way with your body."

"Yes! I want it so bad!" Mercy draped her arms over both of Jack's shoulders, her fingers digging through the shortly trimmed hair at the back of his head. "Bitte!" she begged through her delirious haze, "Give it to me! Fuck me!" Her crisscrossed boots bounced behind his back as Jack rutted into her with furious speed. Mercy leaned back over the desk and stretch herself out with feminine grace, jutting her chest upward. Her bountiful cleavage displayed prominently, both perky breasts straining to break free from the skimpy costume keeping them confined. 

Jack nipped at her ear, growling into it as he fully lost himself in their little fantasy. "I'm going to fill your slutty pussy with my cum. I'm going to claim you as my own, and then I'll drag you back to my lair where you'll spend the rest of your days being bred as nothing more than my little fucktoy." The force and pace of his relentless thrusts steadily increased, forcing her thighs to open wider as she bore the brunt of each blissful impact.

With her mouth hung open in endless gasping breaths, the young doctor was in no position to resist him. "Take me!" she cried aloud as her lithe body undulated beneath him. Long strands of blonde hair fell across her lovely, pleasure-stricken face as she gazed up at the man plundering her depths, her eyes swimming with lust. "I'll be your pet forever, just don't stop fucking me!" Her legs inched higher up his body, and briefly Mercy hoped that Jack would throw caution to the wind, push her ankles up over her head, and fuck her good and hard into his desk, but the familiar tingle of her oncoming orgasm quickly drove all other thoughts from her mind.

Mercy's vision blurred as the mind-numbing ecstasy reached its crescendo toward an explosive orgasm. She continued to moan and scream like the slutty witch he claimed she was, and Mercy loved every second of being fucked sinfully atop her boss's desk. Her legs tightened around him, signaling her oncoming climax, but the swelling cock buried within her slick cunt beat her to it. Making good on his promise, Jack groaned fiercely as he pumped the blonde doctor to the brim with rich, thick cream. Immediately upon feeling his hot cum spraying her inner walls, Mercy's eyes shot wide open and she released a throat-ruining scream that had to have been heard by everyone within the building. Her hips bucked lewdly against Jack's as she rode out her pleasure impaled upon his endlessly spurting cock.

As their bodies crashed down from their immense highs, Mercy fell backward onto the desk, scattering papers about as she lay fully splayed for his viewing pleasure. Her chest rose and fell steadily with each labored breath, and Mercy languidly licked her lips seductively as she felt his warm seed sloshing within her innermost depths. Jack slowly pulled himself free from her vice-like pussy, leaving her legs fully spread and draped over the desk's edge with her pussy, now battered raw and red, leaking his overabundant cum onto the clean floor. Mercy looked an absolute mess, so freshly and contently fucked, and she glowed with her flushed skin and coy smile. She giggled up at him, trailing a hand over the tops of her breasts. "You really are an animal, Jack."

"Guess so," he said with his own sheepish smile. His cock hung limply between his legs, still dripping with their combined fluids, but the sight of her so delectably offered across his desk caused it to stir and twitch back to life once more. "You ready for round two?"

"Mmm, as much as I would love that, Jack, I think we should probably rejoin the others downstairs before they begin to wonder where we've disappeared." She winked slyly at him as she brought herself to sit upright once more. "It wouldn't do for the others to discover the head of medical research is sleeping with their commander."

"Sleeping with?" asked Jack with a brief yet respectful chuckle as he pulled up his pants. "Is that what you're calling it?"

"Alright," said Mercy with her own devious grin. "A torrid love affair of baseless sex and mind-blowing orgasms."

The commander laughed more fully and nodded in agreement. "That sounds more like it to me."

"Good." Mercy stood up, elegant as an angel if one were to ignore the obscene sight of her cum-drooling snatch. She stepped toward Jack, swaying her hips wide for emphasis, and pressed herself up against his toned, muscled body. "You know just how to treat a girl right," she said before leaning in and capturing his lips in a passionate kiss. Their lips locked for several long seconds, savoring the taste of each other's flesh and basking in the afterglow of their tryst. Mercy pulled away at last, gazing up longingly into his deep blue eyes. "And how to reduce a girl into a quivering, cummy mess."

Jack winked back at her. "Any time, Dr. Ziegler. My office always has an open-door policy." He turned and left, leaving Mercy alone in the empty office. With a long, drawn-out sigh, Mercy seated herself back onto the desk where just moments ago she was screaming like a whore. With eyes closed and head leaned back, Mercy spent several minutes recalling their passionate lovemaking as she idly fingered her sopping pussy. She pushed two slender digits inside and slowly worked them in and out, wagging the fingertips to swirl about the cum her commander had deposited within. Soft moans came from pursed lips as Mercy worked herself back into a heated frenzy, all the better to jump the next hapless man she ran into that night. 

Satisfied with her reawakened libido, Mercy pulled her fingers free and slowly cleaned them, her tongue flicking out with cat-like grace to lick each finger like the world's most delicious treat. She hurriedly recovered her black shorts, placed the pointed hat back atop her pretty blonde head, and readjusted the witch's dress so as to less obviously appear as though she had just been fucked in it. With a confident and hungry smile, Mercy strolled out the office and began prowling the corridors of Overwatch headquarters, seeking her next prey.
