My Black Sheep Ch. 02

"You know what the worst part is? I'm not surprised. I'm really, really not." She grabbed Shelby's face, thumb and index fingers split wide to grab her between her jaws, and the pressure of it forced her mouth open. She turned Shelby's head this way and that, inspecting God only knew what. "Disappointed, but not surprised. Kinda wondering why I bothered to fight it."

Shelby looked down at the bottles as Amelia unscrewed them from the suction cups. Then her little sister pried the cups from her breast. Her nipples were enormous, bulbous, and colored an angry red. Amelia smiled at them, but otherwise left them alone.

The relief was intense. Shelby sighed slightly and closed her eyes. The sudden release of weight from her breasts was worth savoring.

She heard the sounds of pouring liquid and opened her eyes to see Amelia pouring the milk from the smaller containers into ones that were twice the size. They had the same threaded fitting at the top. She'd looked at a similar product in the stores and guessed that the set was designed to be interchangeable. The larger bottles weren't designed to attach to the pump, but the lids were designed to be able to be used on any of the bottles. Some of them even came with lids that could be used for feeding directly.

"Careful with that," Shelby said, hoarsely, and was amazed at how dry her throat was.

"You sound parched. Something to drink?" Amelia asked, offering Shelby the large bottle. It was around half-full.

Shelby winced away, unable to hide her disgust. "No, that's for—"

"Kelsi," Amelia said, dismissively. "Right. I almost forgot."

"What are you doing?" Shelby asked. She watched as Amelia set both huge bottles down and affixed a bell-shaped cup to the top of it, and then said, "Those don't go—"

Amelia made a shushing sound, and said, "I'm making improvements. It's part of the process."

She smeared a little lube around the inside lip of the bell, and then started playing with tubing behind and underneath her.

"Ames?" Shelby said, twisting this way and that to look around her arms and tits.

"You've only experienced a third of what this can do."

"Amelia?"

"The buyer wasvery specific about the suction levels he wanted. Took me a while to figure out, because these cheap ones max out much lower and I'm not exactly an engineer, but yeah. Some relief valves, some connective tubing, a couple extra pumps, and there you have it."

"What do you meana couple extra pumps?"

"I thought you weren't scared?" Amelia turned those cold, dark eyes on her, and Shelby quivered.

"What do you mean, a—" Shelby's protests were cut short when Amelia reached around from behind and pressed one of the huge suction cups, complete with its enormous bottle of breast milk to her right breast. A fist-sized amount of her right breast was violently drawn into the cup, morphing a cylinder's worth of her breast flesh. It was distorted and only recognisable by the nipple that was being pulled in and out by the alternating vacuum, now running double speed, and Shelby cursed violently.

Satisfied it was in place, Amelia stopped supporting the weight of the bottle, and the sum total of what she'd already pumped was instantly stretching her breast again.

"Oh god," she whimpered.

"God can't help you now, Shel. I think he'll have turned his back on you when you decided to seduce your sister."

"Ames, Ames, it's too heavy. I'm...Fuck! It's too strong! Turn it—fuck, Ames! Turn it off!!" Shelby panted, closing her eyes tightly against the stimulation and gritting her teeth.

Her little sister affixed a clamp to the frame below her, and then fastened it tightly around the cup, so that it wasn't just that the pump applied suction, it pulled her breast down. It hurt like an absolute bitch.

"It's a shame I don't have my camera. The contrast here is marvellous." Amelia said, distractedly, as she gently lifted Shelby's free left breast. "Oh well."

Her little sister then repeated the move with Shelby's left breast. She cried out, and thought for a moment that she was gonna pass out. Barring that, she was sure she was going to throw up, but she focused. Concentrated on her breathing. Fought to keep herself under control. Little by little, as she focused on the pain, her depravity set in. The creeping sensation that she not only deserved this but had earned it with her shitty behavior sent her libido into overdrive.

Shelby had almost managed it when Amelia pulled her panties to one side. She felt Amelia's fingers gently trace over her labia then pull one of them out.

"Fuck Shel," Amelia said. "You gave birth to two of the tiniest babies I've ever seen, one of them two months premature, and they still ruined you."

Shelby tried to look behind her in shock. What could Amelia possibly mean? She knew it was maybe different, but surely she'd recovered hadn't she? She must have! That is what vagina's were designed to do. It had been two months... hadn't it?

All rational thought vanished as Amelia plunged two fingers roughly between Shelby's labia, and straight into the heart of her. That was all it took for Shelby to cum. Hard.

Shelby gasped wordlessly as the orgasm ripped through her. She hadn't had any warning or been expecting it, which made its effects all the more devastating. She gripped the frame tightly, muscles up and down her arms flexing and surging underneath the skin. Her legs kicked out against the restraints, thighs and calves still impressive and defined despite the years of atrophy.

Then the first wave passed, and Shelby could gasp for air. She felt herself relax, and at the same time her torso lowered itself. The movement was just enough to start her tits swinging. That sudden movement and the sudden stretching pain that went with it wrenched her mind from what Amelia's fingers were doing to her. The pain, and the reminder of her stretched tits being milked sent her spiraling into another wave of pleasure.

"Oh," she just managed to say before she tensed up. "Oh!" Her back arched and there was the anticipation of a fresh round of pain the minute she relaxed. The second wave of pleasure that tore through her was just as devastating as the first, causing her muscles to run dangerously close to cramping.

"You're pathetic," came Amelia's voice from behind her. "That was absolutely pathetic."

"I... I know." Shelby barely managed to get out.

"We haven't even started yet."

There was a pause, and Shelby wished more than anything she could see her sister.

"And look at your cunt. I mean, your labia were big before, but now? I could tie these in a knot." There was a creaking in the frame, and suddenly Amelia's lips were just beside her ear. She whispered, "Shall I do that? Put 'em in a big double knot, so Davis stops knocking you up? Hang a Closed for Business sign on your cunt?"

The shadow in her peripheral vision retreated and Shelby groaned, but the pause was only momentary. She felt Amelia stretching her labia, but she wasn't sure how her sister was managing it with her fingers inside her as well.

"You just swallowed four fingers without me even trying. What the fuck." Amelia chuckled darkly. "Maybe, instead of a knot, I can make a tie these into a bow so your piece of shit husband can stand the sight of it."

"Oh god," Shelby moaned, biting her lip hard.

"I wonder..." Amelia folded her thumb against her palm and pushed. Her labia splayed willingly around the invading hand and, with a plop, they closed up like a sheath around Amelia's wrist.

Shelby's head flew back. Her lungs seemed to seize, and the halting motion sent her tits swaying ponderously. She saw starbursts on the insides of her eyelids. Every muscle in her body seized. Her sister said something behind her, but Shelby missed it.

She was not aware of how long she remained in the bright white light, but over what felt like hours she did become aware of a high-pitched screaming. It filled the room around her. It didn't seem possible that she could be making that sound. From behind her, it felt like Amelia was intentionally driving the sound, with twists and juts from her fist causing the shriek to ramp up in pitch or volume.

"Oh yes, fucking grindon it," Amelia snarled. "Youcan't stop screaming, but let's not let a little thing like that get in the way of another hard O. Fucking hell."

At some point during the whiteness Amelia had started twisting her fist further into Shelby's cunt, knuckles brushing against something much closer to her core, and Shelby wondered if that was why the orgasm lasted so long.

Deep breaths,Shelby told herself, as she fought to regain some level of control.Deep breaths.The only problem was that taking deep breaths was sheer agony for her chest. She tried letting her head hang forward, and that changed the angle that the pumps were pulling at her breasts from, but only by a minute degree.

"No you fucking don't," Amelia said, laughing.

There were a series of clicks behind her, like dials being turned. The suction cups on her tits started pulling harder, and she realized that Amelia must have increased the setting even further.

She watched her breasts pulled even deeper into the cylinders. The flesh looked shiny and swollen inside the plastic, spreading and stretching to fill the space. She just had time to appreciate the view before the pain hit her, and the pain was intense. Her eyes flicked closed, but she summoned her willpower to force them open. She wanted to see the effect. She wanted to watch it happen.

Sure enough, at the bottom of the cup the milk was flowing from her tits again, in tiny rivulets. She managed a half-smile then surrendered to the orgasm.

This time it was everything.

She lost all track of herself and time, and just remained a quivering mess. Every muscle seemed to hurt, and at the same time every muscle felt pleasure. There was such a torrent of hormones, adrenaline, oxytocin, and dopamine surging through her. She couldn't hear, she couldn't see, and she couldn't taste. All she had was the euphoric sensation of the orgasm as it dragged her deeper and deeper into the warmth within. She couldn't tell if it was four or five orgasms strung together in rapid succession, but in the end it did not matter.

At some point she realized that Amelia was working her fist in and out, but Shelby had no idea how long that lasted, or when it started, or when it finished. Her body went with it, but her mind was absent.

Her next conscious thought, some indeterminate amount of time later, was noticing the lack of that very same fist.

Amelia walked around to face Shelby, and squatted in front of her with a dead expression on her face. She held up her hand. It was covered in fluid ranging from thin and cloudy to a thick, creamy white.

"That,dear sister, is all you," she said, twisting her hand this way and that and gazing at it in awe. "Your cunt is just as needy as you, Shel. Sucked me right in. It's ridiculous how easy that was. I'm not even sweating."

Amelia smirked, wiped her palm across Shelby's left cheek, and smeared then the back of her hand across Shelby's right cheek. It filled her nostrils. Filled her lungs.

"I don't remember you being this noisy. Do I need to shut you up before we start on your ass?"

"I... water?" Shelby croaked, and even that hurt.

"Oh don't worry," Amelia laughed. "I've got something for you to drink."

Then she turned and walked towards the opening.

"Amelia," Shelby croaked.

Her little sister didn't even look back. She just shut off the lights and moved the panel into place, plunging Shelby into complete darkness. Just her and the constant agony of the breast pump, emptying and stretching her tits at the same time.

The darkness robbed Shelby of her sense of sight, which instantly heightened all her other senses. She could smell the metalwork, her sweat, her milk and, most worryingly, her arousal. It was smeared all over her face, and quickly drying. The only sounds were her ragged breathing and the angry sucking sound of the pump. The only thing she could feel was the sucking and stretching on each of her tits. She had no way of knowing how full each of the containers now were, but she was pretty sure her breasts weren't empty yet.

She tried her best not to think of it, but there had been a time, a few months back, late at night, when she'd expressed in a brain dead, sleep-deprived frenzy, and she'd gone too far. She remembered how empty her tits had been. She remembered how loose the skin had been, like two used condoms with cum leaking out at the ends.

She hadn't emptied herself with such a powerful machine that day, and she hadn't kept all the milk hanging by suction at the end of her tits. She couldn't help but think of how that weight would stretch her skin with all of it concentrated on her nipples, the lowest part, and not evenly spread across that much skin.

It was not the first time Shelby had thought her tits would be ruined, and it wouldn't be the last, but there in the dark with nothing else to focus on, it was all consuming. That thought alone brought her to another orgasm, and left her sobbing like a little girl.

A few minutes later the door slid open abruptly, light streaming in around the silhouette of her little sister, and Shelby jerked. Amelia took one step inside the room, paused, sniffed twice...

...and chuckled.

"You know," she said, as she reached over to turn on the light. Her sister walked around behind Shelby and set something heavy on a metal table, and Shelby couldn't help but drool just a little at the way her sister walked. It was a gait that oozed confidence, and deep in the recesses of her brain she remembered that there had been other goals. Other ways to get what she wanted. "I gotta admit. I spend a lot of time trying to deny this, but it feels good."

Shelby wailed when, unexpectedly, Amelia slapped her left ass cheek with an open palm. Her whole body twitched and squirmed, rocking back and forth in the rig. Her sudden reaction caused her torso to pull forward, only her tits couldn't move with her. They were attached to the pumps that were attached to the bottles that were attached to the frame.

"Ahh, fuuuuuck," Shelby cried out as she felt the suction cups tear at her tits. She closed her eyes and fought hard to control the pain.

She reopened her eyes when she had control, then winced when Amelia dropped down to one knee next to her, smiling broadly.

"My hand," she whispered, reverently, holding up her right hand while her left held the wrist. "Do you feel that throbbing?"

Shelby nodded, glancing sideways without turning to face her sister. She opened her mouth to answer, but what came out was a mewling whimper.

"That good, huh?"

Instead, since she couldn't get her tongue to function, Shelby nodded weakly. Amelia clapped her on the shoulder and bounced to her feet with a manic grin. When she looked down, Shelby saw that although no more of her breasts had been pulled into the bell-like cups, what had been pulled in had swollen to fill the space. Her nipples were pulled down and funneled into the narrow opening where the cup met the lid of the bottle.

"Now," she said, pitching up her voice to fill the space, "let's see if we can't go one higher."

Two sharp clicks rang out, and Shelby squealed. Her breasts already felt like they were too small for the space, like they were already pushing out on the plastic so hard that they might crack it. Too much of her inside too little of it. The extra suction only really served to tug on the tips of her nipples that much harder, but that was excruciating enough.

Shelby hissed through her teeth as she tried to adapt, but it was so much. The dull ache of the swollen flesh contrasted against the acute sting of her nipples being forced down the narrow chute, and the resultant sensation left her dizzy and light headed. Gloriously, deliriously light headed. She could feel the pain filing down all her sharp edges.

"More," she groaned.

Behind her, Amelia just chuckled. "You know, Shel, you were right. I didn't want to say it, because"— she paused there to laugh, briefly but hysterically —"Ihave been thinking about this. Sometimes, it feels like I just can't stop."

She whipped her head around at a heavy metal clang right beside her, and saw Amelia shoving a metal pipe down into a hole in the side of the rig that seemed prepared for it. She followed the pipe with her eyes, down and then up, and her eyes got larger and larger as Amelia grabbed a fistful of her long, blonde hair and yanked back.

It stung like crazy. The pressure was dispersed across her entire scalp, but Amelia was more than strong enough for this. Shelby had to bow her back slightly, which was agony on her tits, as Amelia grabbed and grabbed and grabbed, working her hands back and over her scalp to scoop up every hair. There were a few more tugs, less severe, but her head was pulled back a tiny bit farther every time.

And then Amelia came to stand in front of her, with both hands held out, and her head was still stuck. Her eyes rolled wildly, trying in vain to look around behind her skull, but she knew what had happened; it didn't take a genius to work out that Amelia had knotted her hair around some hook, contorting her even further. The more she twitched, the more it hurt, and her natural reaction was to whine soundlessly.

Amelia spat on her, with most of it landing solidly within her mouth. On her tongue. A bit was on her lips and cheek, but that barely registered compared to the wad of it in her mouth. Shelby twitched hard at that, which hurt pretty much everywhere by that point. Her arms and legs were on fire, aching from so much pushing and pulling. As she fought to bring the twitching down to a shiver, she swallowed her sister's spit, and it was like mana. It nourished her, fed her, and reminded her exactly where she fit into the grand scheme of things. She was nothing, worth nothing, and that felt perfect.

In her melancholic ecstasy, Shelby lost track of her sister. There was about one second of cool wet something pushing between her cheeks, and then more, and then more. It was slow, but it was unyielding. Fingertips, coated in a thick, jelly lube, were pushing in against her ass.

"Ow," she whined. "Ow,ow ow! Ow! Ow!"

This wordless prayer did nothing to spare her. The tip of one finger, Amelia's middle finger she thought, had already penetrated her inner ring, with her index and ring fingers pressing harder and harder by the second. The pain was so sharp, and so sudden, that tears sprang from her eyes almost instantly. She tried to ask Amelia to slow down, but her vocal chords refused to listen to her brain and what came out instead was a long, warbling inhuman sound.

"I like that," Amelia commented distantly. "Feel free to do more of that."

Three fingers, with more coming. Shelby had worked this one out already; her sister was going right for the fist. The pinky was nudged in between the rings, but her asshole did not want to give.

Shelby was no stranger to anal sex. Over the years it had become a celebration treat for her husband; birthdays, christmas, anniversaries, a game victory. He always seemed to be harder, last longer, and cum far harder in her ass than any of her more suitable holes. Never in her wildest dreams had she imagined Amelia would target her ass, yet it was so obvious; what better way to punish her. But a fist in her ass? That would be far too much without a longer pause to relax. Her ass was still tight, but it wouldn't be after a fist. She didn't want a fist in her ass. At all. Not her sisters fist, not anyones fist. Her only hope was that Amelia might give up.

Except that Amelia never gave up on anything she started. Ever.
