Overwatch: Cloud Nine (Patreon)

“What is this?” Sombra demanded as soon as she woke up. She was strapped down to a bed, totally naked, and she didn’t feel nearly good enough for that to be explicable for her. It wasn’t even a normal bed, more some kind of padded bench that reminded her of a… a doctor’s table.

“I think you know what it is,” Mercy said, her wings close to her back as she swept through the lab. “You snuck into my lab, I caught you—“

“I remember,” Sombra said quickly. “I remember!” The one thing that wouldn’t improve her mood was reliving how Mercy had overcome her. “Tell me, what will it be now? Drag me off to prison? Or kill me outright, puta?”

“Actually, I had thought of something a bit more interesting.”

“Oh?” Sombra asked, glancing down at her naked body with a leading kind of interest.

“Your cybernetic enhancements,” Mercy continued, her graceful voice lilting utterly above Sombra’s innuendo. “I’d very much like to do research on your physical responses.”

“And if I refuse?” Sombra asked.

Mercy just smiled at her. “Does a needle ask blood whether or not it wants to be drawn?”

Sombra smiled back fearlessly. She was actually a bit gratified to find some darkness in Mercy. It was the ones who were seemingly all sunshine and flowers that really worried her. Mercy being a bit of a bitch meant that they had something in common.

"How did you sleep last night?" Mercy asked quietly.

Sombra leaned back on the bench. "Fine," she smiled with mocking insincerity. "Except for all the thoughts of those I’d wronged."

Mercy scanned her smile as if charmed by her. "Did you need anything?"

Sombra flushed. "I don't know what you mean."

"Yes, you do," Mercy persisted. "Did you play with yourself before you went to sleep?"

The color in her cheeks deepened. "Yes," she whispered, "What’s it to you, blondie? Looking for tips?"

"It's all right, Sombra," Mercy said, her voice warm and understanding. "You don't need to be shy with me. It's quite natural and normal—especially for a very highly sexual girl like you."

Sombra narrowed her eyes. "Highly sexual?"

She nodded. "Very. You feel very passionate sometimes, don't you Sombra? You feel that you need some form of sexual outlet?"

"Oh, you don’t?” Sombra retorted.

"Of course. That's why I'm going to examine you—find out your sexual threshold."

"W-what!" Her face was shocked, eyes frightened. "Why?"

"I'm doing research. I'm very interested in the extent and intensity of orgasms."

Sombra’s mouth dropped open, then she gave a nervous laugh. "Interested in orgasms..." She laughed again. "Who isn’t?!"

"Scientifically," Mercy said.

"Of course." Her voice was dry.

"Nothing to be frightened about, Sombra. I won't hurt you and you'll find it a very pleasant examination--very satisfying, too, I think."

Her words beat a little thrill through Sombra’s body. Just what will she do? Is she actually going to make me orgasm? A sensuous ball of expectancy formed in the pit of her stomach.

"Are you..." she paused, swallowed, then: "Are you going to eat me out? Finger me? Or just pick up a dildo and go to town? Pinche pendeja!"

Mercy stared at the sheen of dampness on her legs: she was sweating and excited. "No," she told her. "There are other ways--very enjoyable ways--of gathering information on your responsiveness."

Sombra leaned back, flattened herself on the table, and closed her eyes.

She nodded, smiled reassuringly, then drew her fingertip across the nipple of a breast very gently. Sombra stiffened, then the nipple protruded and hardened.

Sombra’s eyes opened and her color deepened. "Why'd you do that?" she asked in a whisper.

"Testing," she said softly. Mercy moved down the table. "Open your legs," she urged gently. "Part your thighs for me. I’m sure you already want to."

Sombra closed her eyes as her legs and thighs parted widely inside the strap that held them down. Mercy reached down and thumbed the dark triangle of hair at the base of her belly, opening it up at the streak of violet dye that ran through it. She let her eyes rest on the foliage for a moment, then her gaze went down to the inverted tip of the triangle and the slight mound with its thin slit down the center and the pouting vaginal lips on either side.

She placed a finger on either side of the slit then stretched it open. The lips curled open, showing pink, wet tissue within; at the top of the slit, the pea-size clitoris was visible. She touched it... Sombra drew in her breath with a hiss and tiny quivers ran across her belly.

Mercy undid the strap holding her lower body. "Lift up your knees," said Mercy softly, "and let them fall apart."

Sombra did as she told her and she watched her sex ooze open. Bending her head, Mercy stared up into her vulva then moved her hand lower, opened the cheeks of her bottom and exposed the anal opening.

She touched the small red star with her fingertip. Sombra flinched, drew in her breath loudly but said nothing.

"Have you ever had anything in there?" Mercy asked her.

"No!" she shot out the word.

"A man never put himself in your anus?" she persisted.

"No, no!" Sombra said, sounding angry. "I'd never let a guy stick his cock in me like that! Maybe you would, but I—"

"But you yourself," Mercy interrupted intently, "didn't you ever touch that little hole—when you were playing with yourself perhaps?"

Sombra twisted her head to one side. "Everybody touches it a little…"

"Just put your fingertip in very gently?"

"Yes," she whispered.

"And pull it in and out?"

"Is that a crime?"

"And you enjoyed it?" Mercy asked.

"I-I..." she broke off.

"It increased the thrills," she went on, "while you were teasing your clitoris with one hand you pushed your finger in and out of your anus and it heightened the sensation?"

"Yes! Fine!" she breathed, lifting her knees higher as she spoke. "Maybe you don’t know anything about it. Maybe you don’t know what you’re missing!”

"You get a thrill at your anus, too?"

"Ohh," she sighed, "all inside my asshole--it feels like on fire--the thrills run from my pussy to my clit, then all the way inside me--it shatters right through me, I come like crazy!"

Mercy inserted her fingertip inside her anus, felt the wet, warm walls hugging it and was aware of the throbbing inside the aroused flesh.

"You'll like this test," she promised Sombra, withdrawing her finger completely then lightly touching her clitoris. "I'm going to run a very mild current--a mild electrical current--from your clitoris to your anus."

Sombra tensed her body, opened her mouth to voice a protest. Mercy leaned over her face, speaking softly, persuasively. "You're going to orgasm with more intensity than you ever imagined, Sombra. You're going to cloud nine and you'll love every sensual second I give you there!"

"You’re crazy! You’re fucking insane!" Her voice was frightened.

"It won’t hurt," Mercy promised her. “Anything but...”

She wheeled a small cart beside the table, and Sombra lay still, her head turned, watching. That black box with things attached to it, Sombra asked herself, what will it do to my pussy?

There were two cables with small suction cups at the end; Mercy attached them to each of Sombra’s nipples. The cups fitted over her breasts, holding them with their own suction, and a spongy pad inside them pressed lightly on her nipples. The slight contact made her nipples stiffen and Sombra breathed hard with excitement, making her breasts rise and fall, but the movements did not dislodge the rubber cups.

Mercy took another cable from the box on top of the wheeled table; the cable had a slim electrode attached to the end of it. She stretched the electric cord until it was between Sombra’s thighs, then, telling her to raise her knees and part them, she eased open her anus and slid the electrode inside.

"Does it hurt?" she asked solicitously.

"No..." Sombra murmured. “When I get out of this—“

“You’ll thank me,” Mercy assured her. "I put cream on it before I inserted it. Can you feel it inside you?"

She moved herself a little. "Yes," Sombra told her, "but only just. Crazy bitch…"

"Wriggle your bottom," Mercy told her.

She squirmed herself, then nodded. "Crazy, crazy bitch!"

"You can feel it," Mercy nodded, moved beside the table, put her hand on a black knob. "Good. Tell me what you feel--if anything." She turned the knob very slightly. “Boop.”

Sombra lay still for a moment, then her belly contracted and she half-lifted her buttocks.

"You’re such a freak, you know that, completely loco! They oughta lock you up!" she said, breathlessly.

"What do you feel?" Mercy asked, eagerly.

"In-in my ass--it's warm--jerky an' warm!" Her voice was rushed, short of breath.

"Does it hurt?" Mercy asked quickly.

She shook her head. "Oh no--it's like nice… all warm an' nice!"

Mercy nodded, turned the mild current off.

"That’s… that’s better!" said Sombra. She sounded almost completely unsure of herself, like she was repeating words that had long since lost their meaning. “Don’t you dare do that again. I should skin you alive for even thinking—“

"You'll have it again, later," Mercy promised, smiling at her and reaching to another control. "Tell me what you feel."

Sombra shook her head, she wriggled her breasts from side to side. "My-my nipples are getting hard," she whispered. “Pendeja!”

"Yes?" Mercy turned the control again.

"They're ho - it's like little stabs running through my breasts an' they're warm. The-the cups are sucking my breasts, pulling them out, an' I can feel the nipples--they're getting harder and harder..." She shook her breasts, licked at her lips, opened and closed her eyes. She was drooling.

“You’re getting excited, aren’t you?” Mercy turned off the current. "You'll have more of that later, Sombra. Are you enjoying this test?"

She opened her eyes and they were blazing. "I will kill you! I will!" Her lower lip trembled. "Don’t you dare do any more to me!”

"You have a very contrary personality," Mercy said, stretching another cable from the black box.

"Muh-my pussy--you're gonna do something in my pussy?"

There was another electrode attached to the end of this cable, too, held in place by a thick rubber strap which had suction cups at either end.

"Yes," said Mercy, "it's time for your pussy!"

She clamped a suction cup on either hipbone so that the rubber strap stretched over the top of Sombra’s slit. She adjusted the position of the electrode so that it was directly above her clitoris, then tightened the strap so that the end of the electrode was pressing on her clit like a claiming flag.

"Feel that?" she asked.

"Bitch," Sombra whispered. “Goddamn bitch…”

"What's it touching?"

"M-my pussy..."

"But what part of your pussy?"

"My… my… you know what part!”

"Yes," she said, "your clitoris." She turned the dial of an indicator at the top of the box, watching Sombra’s face as she slowly increased the vibrations.

"Oooh, that!" Sombra squealed suddenly, lifting and lowering her pelvis. "Right into me--right through my clit!"

"Hurt?" Mercy asked.

Sombra squirmed. "No, oh no--do it again!"

"I thought as much. Later," she promised, turning the dial back to zero.

Sombra turned her head, swiveled her eyes as Mercy picked up a slim rubber sheath.

"What's that?" she whispered.

Mercy smiled. "Something to keep your pussy warm."

"You-you're gonna put it in inside--push it into me?"

"Yes."

Sombra looked puzzled. "It-it's kinda small, isn't it, Doctor?"

Mercy laughed. "You like big cocks?"

Sombra flushed, closed her eyes.

She leaned close, asked: "You like big cocks in you?"

"I’m not a whore like you!" she protested, trying to sound tough.

"Sombra, you like big cocks up your pussy. I know you do."

"I-I haven't had so many cocks in me..." she opened her eyes, stared at Mercy, indignantly, "an' none of them big, I mean, real big."

Mercy held up the sheath, pressed a button at the end of it and the sheath expanded, becoming longer and thicker. "I can make this as thick as you like, Sombra." Her voice sounded excited for the first time. "I'm pushing it in your pussy then making it get bigger--you tell me when it's the size you like."

Sombra blinked rapidly. "Is-is it hard? Will it hurt me?"

"It's pliable but hard enough. It won't hurt but it'll expand until it's pressing against all sides of your pussy, filling you completely, and it'll touch every sensitive spot inside you as I pull it out and push it in."

"I won’t like it. I won’t!"

Mercy took a tube of salve, squeezed some onto her hand then smeared it on the sheath. "I'll make it soft and lubricated so that it'll slide in and out smoothly; it'll adapt itself to the contours inside your vulva, pressing evenly all over, touching everything, pleasing you quite completely."

She held her breath, bent over her as she opened her thighs and lifted her buttocks with trembling eagerness, then inserted the end of the sheath between the shivering lips of her sex.

"I'm pushing it in, Sombra," Mercy whispered, "and when it's all inside, I'll press the button, make it get bigger and bigger until you tell me to stop."

"You don’t have to enjoy it so much!" Sombra’s voice was high with excited anticipation. “I can tell you enjoy it!”

The sheath slid through the curled open lips, piercing its path into the shivering tissue until its rounded end was flush with the top of Sombra’s vulva.

"It-it's at the back of my pussy..." she said, quaveringly, "I know you’re going to make it thicker!" She lifted her hips, slowly rotated her pelvis as Mercy touched the button and made the sheath expand.

“Yes,” Mercy said. “Because I know you want it to be thicker.”

Sombra closed her eyes, held her breath as the thickness increased; every now and then she'd make a wet, sensuous sound as a fresh part of her sensitive vulva was titillated by the expanding sheath.

Mercy watched the slit stretch open; the soft labia lips curled outward, showing wet, pink tissue until it seemed that the opening could not possibly get wider.

"Is that enough?" she asked, her finger ready to press the button and halt the expansion.

"Just-just a little bit more, Doctor. It's like-like nothing I ever imagined. I've never been so filled before!" Sombra’s voice was dreamy and breathless.

"All right," she said at last, and Mercy pressed the button, then slid the sheath, sluggishly, tissue clinging to its sides, down the quivering vulva before pressing it upward again.

"Oh that, Doctor, oh yes!" Sombra raised her pelvis, tightened her belly into stiff ridges of tension as the sheath penetrated her.

Mercy reached to the controls, switched on the power for the breast-pads.

Sombra gave a low squeal of ecstasy when she felt the vibrations on her nipples.

"Feel it?" Mercy whispered.

"Oh yes, on my breasts--my tits are all hard!" She shook herself, making her breasts swing from side to side, but the pads stayed in place.

Mercy increased the power. Sombra squealed again, more loudly this time. "This is insane! Oh, Doc--you're driving me crazy. My nipples are on fire! Ardiente!" She twitched and jerked her whole body.

Mercy manipulated the sheath, squeezing it in high, dragging it down slowly with sensual twists.

"Inside my pussy--ooooh, all over it, every wet part!" Sombra lifted her pelvis, undulated it and moaned. Saliva was trickling from her mouth and running down her chin until it dripped onto her neck.

Mercy reached to the control for the anal electrode, turned it on.

Sombra’s buttocks jerked, and Mercy, still holding the sheath in her vulva, let her hand move with her body.

"Inside my ass. Eeeeh! It's all hot!" She bounced her buttocks up and down on the table but the electrode was not dislodged.

Mercy reached down and under her, pressed the electrode more deeply into her anus; Sombra’s squeals became shriller.

"My ass, Doc—I’m shaking like jelly--oooh, up inside me, right up the wet hole. The jabs are shooting right into me!" Sombra’s voice was a breathless torrent of sound.

Mercy reached for the control for the electrode on her clitoris, gradually increased the power.

A new note came into Sombra’s voice; a pulse in her forehead started flickering wildly. The saliva that ran from her mouth became thicker. She lifted her knees high, then pulled them back into her belly. Mercy changed her grip on the sheath, reaching under her drawn-up legs, squeezing the length of the rubber tube to the top of her womanhood.

"My clit!" Sombra screamed. "It's outta control!"

Mercy glanced at it; the electrode was bobbing wildly on Sombra’s jerking peak. Each time the electrode touched and sent a sharp stab of current into the tiny muscle, Sombra’s face twitched, her knees pressed into her belly and the contraction of her muscles in her vaginal walls forced the sheath downward with intense pressure.

Each time the sheath was forced down, Mercy jammed it back up, and a fresh squeal of pleasure and pain would spew from Sombra’s lips.

She rolled herself upward and backward and Mercy saw her anus stretching open with the electrode projecting; she placed her finger on the end of it, pressed it in to the limit. Sombra shrieked and her buttocks became a mass of quivering jelly.

Mercy reached to the box, increased the power in the anal electrode. Sombra’s shrieks changed into a babbling stream of obscenity.

"It's shooting up my ass! I'm coming inside it! My ass's on fire; that Goddamned fire in my ass is making me--Eeeeh, Doc!--I'm coming in my ass! It's fuckin' me inside my ass an' I'm creamin'! Madre de dios!"

Mercy swung over the dial, and the current in the clitoral electrode went up to near its limit.

Sombra’s belly became a shivering mass of vibrating muscles and nerves. She saw the clitoris quivering madly on the end of its stem, then Mercy reached out to the second strap and undid it. Now freed, Sombra reached down, pressed her fingers into the base of her belly and pushed upward with her pelvis. 

"Fuck," she screamed, pressing her clitoris against the electrode. "Fuck my clit, you little metal cabron, fuck an' fuck an' fuck!" She writhed in a sexual frenzy. "Doc!" she screamed, "fuck my pussy with that rubber--make it get big an' bigger, all inside me--all over my Goddamned pussy--I'm orgasming all over. Oh Doc--I'm coming in every fuckin' part of me!"

Suddenly, Mercy released her grasp of the rubber sheath; leaving it thrust inside Sombra’s pussy, pressing against the utmost end, and stood beside the couch. Her eyes were excited as she watched the squealing, writhing and orgasming girl--then she turned to the controls, switched them all full on.

Sombra’s gyrations became even more frenetic. Her arms waved in the air wildly, then she reached to her crotch, scratched at her clitoris, squeezing it, pressing it against the electrode with maniacal strength. Her ass bounced up and down, and each time it squashed onto the couch, the electrode up her anus went in more deeply.

"Eeeeh, Doc," she screamed. "Up my fuckin' ass, it's creaming me. I'm comin' all over, Doc, I'm goin' crazy!"

Mercy watched the trickle of lubricant seeping from Sombra’s anus as she writhed in sexual agony. Her breath came more quickly, then she reached to her own crotch and unfastened her pants.

Sombra’s eyes rolled wildly; she was unaware of the doctor standing beside her, totally nude from the waist down.

Mercy reached to the black box and cut off the power in all the attachments. Sombra continued to writhe, jerk and moan with frenzy.

Mercy seized the dead electrode in her anus, yanked it out of the wet, squirming hole. Sombra’s ass still quivered, the cheeks opened and closed of their own accord.

She detached the electrode which had danced its dance of sexuality on her clitoris. The slender spire still jerked, writhed and bobbed. Mercy pulled the sheath from inside the palpitating pussy. Sombra’s vulva still quivered, the lips remained curled open even after the thick sheath was gone.

Mercy jerked the suction cups off her breasts; the nipples were black and iron-hard. She touched them--and Sombra jerked frantically. "Squeeze them, Doc--they're aching, please squeeze them!"

She took a nipple between a finger and thumb with either hand, squeezed with all her strength. Sombra drooled; the unbearable pressure thrilled her. She jerked out her legs, straightened them, but her belly still throbbed; the lips of her vulva still opened and closed, sucked in, pushed out with wet, squashing regularity.

Each time she lifted her legs in the air, Mercy could see the asshole squirming open, clenching shut, and she saw too, the thick lubricant that flowed out.

"Doc," Sombra gasped, her face drawn, "I'm still--urgh--orgasming, still coming. Make me stop, Doc--it's too much. I can't stand it any longer!" Her abdomen jerked up, crunched down onto the table.

Mercy licked her lips. "I've turned the machine off, Sombra--it'll take a little while for the effects to wear off your body."

"How long," Sombra panted, "how fuckin' long?"

Mercy watched her clitoris vibrate crazily; then she saw by Sombra’s expression that she was having a more voluptuous orgasm than ever; she reached down, inserted her finger in her vulva, felt the walls hug it, release it then hug it again with a sweet, sensuous need.

"Not too long," she said quietly; gripping her own sex as though she was holding it back.

"I'm coming again, Doc--I'm havin' another fuckin' orgasm!" Her voice was tortured. Her whole body jerked, then she seized her nipples with both hands, pulled and twisted them with frantic insistence.

"Watching you like this excites me," Mercy said slowly, her voice filled with restrained excitement. "I can see your pussy jerking and squeezing its walls together and I want to join in... you don't mind if I do, Sombra?"

"Turn, urgh--turn off the current, Doc, please!"

"It's already turned off, Sombra, like I told you. You'll keep orgasming for a little while longer. I can't stop it." Mercy watched her jerking body for another second, then added, "Your threshold is quite something, Sombra. You orgasm very intensely!"

Sombra’s eyes dilated. "I know! I know!" she gasped, starting to rock into another shattering orgasm. "What're you gonna do to stop me, Doc. Eeeeh, Doc--I'm coming again an' it's hurting my pussy now--watcha gonna do?"

“I’m going to give you something to bite down,” Mercy said, as she climbed up to straddle Sombra’s face.

***

Sombra was weak and trembling when the sensual spasms abated.

"Oh, Doc," she moaned, weakly, "it was so much, so fucking much, I feel half-dead."

Mercy got to her feet. "I'll get you a drink," she said. "You need one."

"Oh, my God--yes."

She poured her a stiff brandy and Sombra drank it straight, gagged, then blurted, "Why did you hafta do that?"

Mercy had fastened her pants, adjusted her clothing after her torrid sexual fun on top of the quivering girl and now she looked at her with raised eyebrows. "Didn't you want a drink?"

She gave a sarcastic laugh. "Puta… I didn't mean that... Why did you have to fuck me?"

“I didn’t want you to feel indebted to me afterward. After all your orgasms, one or two for me was the least you could do.

Despite herself, Sombra smiled. "That doesn't sound very professional, Doctor."

"I didn't mean it to sound professional--you were quite irresistible, Sombra." She gave her another smile, then sounded clinical when she asked: "And how do you feel now?"

She sighed. "Drained, all drained out. I-I never came so much in my life."

"But do you feel satisfied?" she asked.

She nodded, then gave a shaky laugh. "I oughta feel Goddamned satisfied! If I don't feel satisfied after all those orgasms then I never will be!" She shook her head in wonder. "I've never been flying so high in all my life." She wriggled herself. "My culo's sore--I even came inside my ass--and my pussy's still throbbing and twitching whenever I move." She fondled her still-naked breasts. "My nipples are still on fire. I've only got to touch them to feel… cojamos."

"It'll wear off," said Mercy.

Sombra was recovering fast. "I don't know whether I want it to wear off completely," she said, smiling. 

“Well, that’s the other possibility,” Mercy replied.

“What?”
