K'rra wasted no time stripping out of the sodden jumpsuit. She rolled it into a ball as she went to the fresher, followed closely by Bev. She placed the wet clothing on the floor in a corner. Bent down her ass was the perfect target. Bev slapped her hard, then put a hand on K'rra's back, preventing the slave from standing straight.
"Spread your legs, slut."
K'rra complied. She couldn't remember the last time she'd been spanked, in either punishment or for another's pleasure. As the blows rained down K'rra relaxed, letting the heat and stings ripple through her ass and thighs. She exclaimed loudly, knowing Bev would enjoy hearing the results of her handiwork.
When the blows shifted from K'rra's burning cheeks to her exposed pussy lips, she begged, "Please miss!"
Ignored, K'rra received many more slaps. She reached out with shaking arms, bracing herself against the walls. "Mercy, miss. Please..." Bev seemed to enjoy making the slave dance in the corner.
Finally, the blows subsided. "Get in the fresher. Now."
K'rra complied, propelled to hurry with another slap to her ass as she entered the stall. She was still damp and clammy from the wet clothes, her flesh rippling in goosebumps. A hot shower would feel exquisite. Touching the controls, she dialed scalding water while her mind was still numb from the spanking.
"Stop water," barked Bev. The shower ended nearly as soon as it started. "I didn't tell you to waste my water, you cow."
"My apologies, miss. I thought you wanted..."
The slap across the face stung. "You don't need to think. You only need to do what you are told. Understand?"
"Yes, miss," K'rra replied. Looking down at her feet, she tried to clear her mind. She didn't need to think, only do exactly as told. It was a blissful state, a state of complete surrender. K'rra felt herself slipping into a sedate high.
"Kneel."
K'rra's body moved, lowering her to knees. Her hands reflexively went to the back of her neck. She stared at the floor, watching in her peripheral view as Bev stripped out of her nurse uniform. Even without looking directly at the Human woman, K'rra could see that Bev was in good shape for a woman a little older than herself. Where K'rra was a little plump, enough to add a layer of softness to her slave body, Bev was thin with ribs and bones showing easily under taut skin. K'rra noticed she was also unshaven with a tangle of blonde going grey hair between her legs.
"You want a shower, slut?" Bev asked, stepping into the fresher with K'rra.
"Whatever you desire, miss." K'rra answered. Knowing what was coming she kept her eyes focused on the floor, hooding them to slits and closing her mouth.
Bev placed a foot outside K'rra's spread thighs. The other foot went to rest on a thigh. Her hairy pussy just inches from K'rra's face. "Oh no, slut. Look up at me and open that whore mouth."
"Yes, miss." K'rra complied, looking up past the Human's small breasts to piercing eyes. The smirk on Bev's face said it all. She was enjoying this. Enjoying it sexually.
Without warning, Bev released onto K'rra. Warm fluids rained down, covering K'rra's chest and neck. Bev rotated her hips and pressed closer to K'rra, forcing her stream across the blue slave's face and into her mouth. K'rra clenched her throat, collecting what she could in her mouth and letting her mind go blank. Errant thoughts of being marked, covered in the pheromones of another, of being claimed, flitted through her mind. In those terms, the act was one of ownership, making K'rra squirm.
When Bev finished, she pressed forward, rubbing herself against K'rra's face. K'rra held her mouth open, feeling the warm fluids slosh around.
"Good girl," Bev cooed, "show me what you got."
K'rra blinked and held her face up, mouth open for inspection.
Bev leaned down, looking not at K'rra but in her mouth. She seemed satisfied and demanded, "Swallow it."
Closing her mouth, K'rra forced the fluids down, feeling its warmth crawl down her throat. She blinked and opened her mouth again to show it was all gone.
"You are a disgusting piss drinker. Did you like that?"
"My wants don't matter, miss. I exist to please you."
"You're a well-trained piss-drinking whore then." Bev leered down at her, then turned to the fresher controls, "Shower, water, scalding hot."
The fresher erupted to life, raining down a stream of hot water. Bev soaped herself while K'rra knelt. The heat from the water felt so good as it washed away the tart odor of urine.
"What the fuck? Slave, get up here and wash me. Why am I doing all the work?"
"Yes, miss." K'rra stood and squirted ample handfuls of gel into her hands. She then worked it across Bev's skin, washing the Human woman who turned this way and that. With gestures, she showed where and what she wanted washed.
"Ymm, use your big cow tits to lather me up, slave."
"Yes, miss." K'rra could finally lather herself up, then pressed herself against the Human. She kept her hands free as she soaped Bev up using nothing but her breasts. The implants in her nipples buzzed happily, felt by both women as K'rra pressed herself to the nurse. One of Bev's hands reached down between K'rra's legs, finding and squeezing the clit piercing there.
"This one is buzzing too," Bev said as the slave gasped. "Filthy fucking slut, why should you get diddled when my needs aren't being tended to?"
"I'm sorry, miss. It's not something I control." K'rra said while pressing her larger breasts to the Human's smaller ones. The vibrating nipple piercings were having an effect on Bev's tits with each pass, and the Human grabbed K'raa and began forcing the slave's tits across her own deliberately.
"Fuck. I can barely feel your piercings. I left the wand in the other room. Should make you go get it."
"Yes, miss," K'rra said, moving to break away from Bev.
The nurse grabbed K'rra and held her in place, "I said should. Rinse your piss drinker out."
K'rra turned her head and opened her mouth, letting shower water fill it. She rinsed and spat while Bev continued stroking her cunt. With both fingers and implants working inside her, K'rra was in a sexual daze. She turned her face back to Bev, mouth opened wide.
Bev tilted her head, looking down into K'rra's mouth. Her other hand came up and grabbed the slave by the chin. Fingers traced K'rra's mouth, then penetrated her, pushing back and trying to gag her. K'raa squeezed her back throat muscles against the Human's fingers. Bev looked surprised for a moment, then pressed her two middle fingers deep into K'rra's mouth. K'rra squeezed them and began breathing through her secondary esophageal airway.
Try as she might, Bev could not force K'rra to gag or gasp for air. Even with her fingers buried deep in the slave's throat, K'rra was able to suck air in through her nose and use the secondary passage for breathing.
"You've been augmented," Bev said, withdrawing her fingers.
"Yes, miss."
"Turned into a perfect fuck toy, haven't you?"
"As my owner pleases, miss."
"How many men have fucked you?"
"I couldn't tell you, miss. I was a public concubine in my master's harem. Available to any guest who pleased."
Bev curled her fingers inside K'rra's pussy, forcing a gasp out of the slave. It was too much. Having been unlocked by the doctor K'rra felt an orgasm building. She tried to fight it, but the fingers in both her throat and cunt made it impossible. She shuddered as Bev angrily thrust in and out of her at both ends.
"You didn't?"
"I'm sorry miss."
"You fucking came without permission. And still so fucking tight. Augmented there too?"
"Yes, miss."
"Anywhere else?"
"Yes, miss. My ass as well. And my palms, and fingertips."
"Fingertips?"
"Yes, miss. Muscles that, when clenched, vibrate."
"Of course. To get men off. What about women?"
"My augments were designed to please all." K'rra specifically did not talk about the additional glands and hormone secretions, especially to a medical professional.
"But nothing for the tongue?"
"I underwent extensive training in tongue manipulations, miss."
"Oh?" Bev asked, "prove it."
K'rra tipped her head back and parted her lips. Bev grabbed a fistful of hair at the back of K'rra's head and pulled the slave to her mouth. Their lips locked, and Bev forced her way into K'rra's mouth. The kiss, invasion, and piercings buzzing furiously made K'rra weak in the knees. She sighed a long exhale and wanted to melt into the naked Human woman. K'rra's tongue wrapped around Bev's. The slave then began to flick her tongue muscles, creating a wave of flesh against Bev's entwined tongue.
Bev stiffened and pushed K'rra away from her, "Stars... that is... something."
"I hope you enjoyed, miss."
"We'll find out. Right now. Stop shower. Dry twenty seconds."
