“There’s nine hours before we get to Obeza,” Kaster said. “Slave, go warm my bed.”
“Yes, Sir.” K’rra said from across the room.
Kae touched Kaster’s arm. “I’d like to join.”
“Why?” Kaster asked.
“I could watch through Focus from my own room, but I’d like to see it with my own eyes.”
“You said that if I trained you, I could enjoy the same services,” Kaster replied.
“Are you taking me up on that? I was hoping the two of us could use your slave girl,” Kae said. 
K’rra stopped in her tracks next to the two. This direction of the conversation was making her anxious. She’d been delighted her Master wanted to use her. She also found Kae attractive and commanding in softer ways than Kaster. The thought of the two of them using her at once, however, made the breath catch deep in her chest.
“It’s been a while since I fucked a free woman,” Kaster said.
“It’s been a while since I fucked a man,” Kae mirrored his reply then nodded to K’raa. “Still want her to warm the bed?”
“Think of her as a marital aid,” Kaster said.
K’rra was crestfallen. Instead of spending time with her Master, she’d be a third wheel, helping them enjoy each other while she assisted as needed. She fought the feelings down. The thoughts were inappropriate. A slave should be happy to be of any use at all.
“I don’t have implants,” Kae teased, “you up to the challenge of working without those marital aids?”
“I may not have your persuasion techniques, but I think I can manage,” he said.
Kae smacked K’rra hard on the bare ass. “You heard your master, go get that bed ready for some fucking.”
With a yelp, K’rra went to Kaster’s room. As she entered, she stole a glance back to see the two embracing in a hard kiss. Kaster’s hands were all over Kae’s back. Kae, though, had a hand buried in his hair, forcing him down and stealing hard kisses from him. Something about the way Kaster yielded to the woman bothered Kae. She didn’t like the dynamic of Kaster showing any sign of weakness to another.
K’rra quickly pulled the blanket and cover sheet down to the foot of the bed. She considered placing them on the floor, but some masters were particular. She didn’t imagine Kaster was, but she was unsure of Kae. She left it as is and kneeled at the foot of the bed facing the door. Even with her eyes downcast, she wanted to watch when they came in.
They entered the bedroom as one, their arms still entwined, still pressing their lips to each other hard. K’rra’s breath caught. She knew exactly how it felt to have Kaster’s lips crushing hers. Kae ripped at his shirt, tearing it free. Kaster reciprocated by yanking Kae’s tight top off over her head.
The two stood smashed into each other. Their lean, muscular bodies pressed tight together topless. K’rra admired the muscles on each from years of training. She also envied Kae’s smaller, firmer breasts. The younger woman’s nipples were sharp and hard, her areolae much smaller and more distinct than K’rra’s. Kae was also thinner, more muscular, and boyish than the older slave had ever been. K’rra wondered which body Kaster truly appreciated more and didn’t like her initial feelings.
They moved past the prostrate slave, still stroking and deep in their kiss. Kae pushed Kaster back, and when he sat hard on the bed, she was at his fastens unbuckling him quickly. He laughed as Kae ripped his billowing trousers off and flung them across the room. He was hard, pointing to the ceiling. Kae didn’t notice she was too busy tearing her own leggings off to join him in nudity.
“Get over here,” Kae demanded. K’raa scrawled on hands and knees to the standing woman. One of Kae’s hands was wrapped around his cock, stroking him slowly. Her other hand went to K’rra’s hair, pulling the slave girl’s face up into her master’s crotch. “Get it wet.”
K’rra opened her mouth to be shoved on Kaster’s cock. The hand in her hair shoved her up and down the shaft, sending it to the back of her throat. K’rra’s gag reflex had been removed, so she swallowed, letting her Master feel the muscles that had been added as a replacement. He groaned loudly. 
Fire burned across K’rra’s scalp as her head was yanked backward off her Master’s cock. 
“I said get it wet,” Kae said with a slap across K’rra’s face. “I’m going to get that cock off.”
K’rra was then shoved down again, her Master’s cock filling her mouth. She opened her mouth and let saliva flow, coating him quickly. The fist in her hair jerked her back and forth, ensuring Kaster was well lubricated. Finally she was yanked back free, her face covered in her own saliva.
“Get up on the bed,” Kae demanded, “And guide him into me.”
K’raa climbed up onto the bed. She didn’t relish the thought of Kaster fucking Kae. That was supposed to be K’rra’s duty. The idea of using her own hands to guide him into another woman was even less desirable. She’d done this many times for Hol Vydon’s guests, but this was the first master she was giving away. 
Kae climbed up atop Kaster, her hands on his broad chest, her lips hungry on his. K’rra moved to the side, a delicate blue hand slipping between their pink bodies to grab her Master’s beautiful cock. She wanted to slip it back in her mouth, to feel him climax in her and know that he was hers just as she was his. She gripped the base and guided it up as Kae pushed herself down. It took a couple of attempts, but finally, K’rra felt the head of Kaster’s cock nestle in between the younger woman’s lips, then slide in.
Groaning, Kae sank down on Kaster, crushing the slave's hands in between the two. K’rra released him and tried to pull her hand free, but Kae barked, “No! Keep holding his cock in me.”
With a pained sigh and wanting to touch her own burning cunt, K’rra wrapped her fingers back around her Master, feeling the free woman’s sopping cunt glide against her hand. 
“Are you going to open your Focus?” Kaster grunted as Kae slid up and down him.
Kae only grunted back in return as she rode him. Her tempo quickened and K’rra could feel her soaking.
Something shifted. K’rra didn’t the words to describe how her consciousness was suddenly changed. She felt as if she had a cock, and it was buried in something tight and wet. She was fucking a painfully tight little cunt, or, the painfully tight cunt was fucking her. The thrill of it made K’rra gush with need, she wanted to feel that cock, achingly hard, buried in her.
She also felt herself getting filled. It was deep and satisfying, filling and stretching her, but it wasn’t her. She could feel Kae getting fucked as she thrust her cunt down to take all of Kaster. It felt good and lovely, but it didn’t tickle her right. She wanted something softer caressing her, sucking at her, wanting to feel huge squishy tits against her own smaller ones.
Underneath that, however, was a wicked thrill. Something dark and dangerous. A sick, haughty need to hurt and relish how the one thing the poor little slave girl wanted was all hers to take. She enjoyed feeling the hurt, the anguish, the selfish refusal to give to another. Kae was delighting in using Kaster, not for her own gratification, but as an implement of torture. She got a wicked thrill hurting K’rra. Feeling it herself, K’rra felt both aroused and horrified at once. She delighted in the torment and enjoyed the humiliating pain that came with it.
Unable to stop herself K’rra reached back and touched herself. Her orgasm was immediate. She came to thoughts of torturing herself and enjoying the torture. She loved and hated the way Kaster felt fucking someone else. He was hers, and he was free to do as he wished, she loved that she could do nothing but accept his joy in having the choices she did not.
As K’rra cried out, Kae rolled off of Kaster. “She’s such a needy little bitch. You should fuck her.”
K’rra lost and quivering on hands and knees, felt Kaster move behind her. She felt his hands on her hips, and relished how much he owned her. She basked in the feel of owning her and being owned at once. When his cock touched the hand working her pussy she grabbed him and slid him in with one thrust back. She was filled and could feel how he felt to be engulfed at once. The dual sensations made her want to cum again.
“Don’t you dare!” Kae commanded. The free woman repositioned herself, then pulled K’rra’s face into her moist fragrant cunt. K’rra could smell both Kae and Kaster mingled there together. She opened her mouth and pressed it hungrily to her mistress. She felt her mouth on the younger woman’s pussy from two angles. She was being devoured and devoured at the same time.
With a climax threatening K’rra screamed into Kae’s tight box. One of her hands slid fingers inside, while behind her, she stroked herself as Kaster drove into her. The pain of the incoming climax was unbearable, threatening to break her in two. She cried, begging muffled and incoherently for release as she was used violently by the others. They both enjoyed fucking her, and she could feel it through both their senses at once. And she, the tool of their lust, delighted that she was such a good girl.
“Oh, stars! Fuck yeah. I’m cumming,” Kae hissed. “Kaster, fill this little cunt.”
He grunted and flooded K’rra with burning heat. Wet slopping noises filled the cabin
“Cum for us,” Kae blurted out between her own climactic cries. And K’rra did.
She felt each of the orgasms separately, together, uniquely, and at once. It shook her to the core. One washing into the next. Crashing waves of pure pleasure that erased all other senses. She could neither see nor think, the whole of her being torn asunder in blankets of unending bliss. She was the lightning rod of all their lusts. A smothering white ecstasy washed her from existence.
Her body danced, floating on sensation. She could feel both Kast and Kae touching her, fucking her, kissing her, and flooding her with all the sensations they felt as they did so. Time distorted, and K’rra rode an endless series of orgasms and blinding white.
When K’rra came too, still quivering and shaking, two sets of hands stroked her body.
“Drink this,” Kaster said, pressing a flask to her mouth. K’rra sucked eagerly, her dry mouth needing the cool soothing water.
“She could have taken more,” Kae said. They were each lying on opposite sides of her, their faces hovering over her as they spoke and stroked her. When Kae’s fingers stroked pussy lips or nipples, it would cause an involuntary rack of quakes.
“Let her sleep,” Kaster said, reaching down to cup her sodden cunt. She wanted to melt into his hand, all of her heat pouring through her hole into his loving touch.
“Sleep then, little slave…” was the last thing K’rra heard Kea say as she fell into oblivion.
