Kairi was impressed. She was painfully aware that Sven had money, indeed her life had become his in an attempt to liberate some of it from him. But seeing the yacht moored in the upscale marina really brought it home. The floating palace of white metal, chrome and glass was right through millionaire playboy and nearer bond villain to her uneducated eye. 

Admiring the boat at least took her mind off her current predicament. When Sven had first announced she would be accompanying him and Beth on their holidays Kairi she had been worried that she would be making the trip as a floor cleaner. So she had been more than a little relieved to have the cleaner paraphernalia removed from her leaving her back to her more familiar truncated form. Kairi really had not been keen on that particular part of her adventure. Given the continued absence of her poor little clit she had long since given up any hope of genuine sexual relief for herself but it had taken a stint as a janitorial assistant to realise just how much she had compensated for this by taking a totally disproportionate degree of pride in being able to satisfy others, her users. It was clear to her now that whatever the deprivation that lay ahead she craved being the source of sexual pleasure. It was a sobering thought as Kairi had no idea whether the feeling, need even, was down to the magic or something more deep seated. How would she feel at the end of the year ?

Beth picked Kairi up and carried her onboard, through a lavish salon and down some steps. Kairi felt a shiver of delight as she was set on a bed in a luxurious cabin and arranged carefully amongst the other pillows. Finally she was to be Sven's bed companion again. 

"I am flying on to Havana so Sven will need you to keep him satisfied till the yacht gets there."

Kairi nodded and settled down to wait, excited to be back to her accustomed role. She nodded in and out of sleep listening to the sounds of the boat being prepared to depart. Finally as the sky outside the small porthole windows dimmed the door to the room burst open and Sven stormed in. 

"No no this won't do at all. Beth... Beth Beth Beth. Sorry K . Beth is testing me. We are getting married next month and she thinks that I can't give you up. Silly isn't it, she's on the edge of being jealous of a dumb ass sex slave. So we had better arrange for something else for you to do for the voyage ... "

Sven dragged Kairi to the centre of the bed. 

"It does mean that your final month with us will be a bit different than I had imagined, but Beth... Oh fuck t, its just a couple more days.."

Sven pulled his clothes off impatiently and jumped onto the bed. Kairi beamed with pride at the thought of being used as she should be once more, and couldn't wait to remind Sven of exactly what he had been missing out on. She grinned even wider as he popped one of his little blue pills and as the yacht slipped its moorings Sven pulled Kairi closer and used each of her three holes thoroughly. Kairi was in heaven. She used every trick she had learned to make sure Sven appreciated every moment with her. Muscles she previously didn't know she had clamped and squeezed the passion out of him, her total lack  of gag reflex helped her drain him dry. Finally he was spent and he drifted into a deep sleep leaving Kairi sweaty, sticky and laying on her back at the foot of the bed.  Kairi dozed happily. A part of her knew that she should definitely not be enjoying her time with Sven this much. But she was living to be used. She guessed her experiences to date had served to conditioned her somehow. Regardless of the impossibility of true sexual satisfaction for herself, or indeed taking any leading role with Sven, she spent all her time thinking of him touching her, being inside her and how she could make sure he was as sated as possible.  

It was a scene they repeated several times during the trip, leaving  Kairi hoping they would never reach their destination. But one night as she watched the sun rise through the portholes while Sven snored softly she heard a flurry of activity and assumed the yacht was pulling into port. There was a loud clatter as the anchor dropped. Just a few minutes later the door to the stateroom burst open and Beth stormed in. 

"I knew it. I knew you couldn't leave the freaky little slut alone, even now..."Beth glanced down at the huge rock on her finger pointedly." I can't be sharing you with her... I can't compete with that. I am a real woman not some pathetic fuck slut!"

Kairi was terrified. Sven was struggling to shake the sleep away and not saying much, mumbling sorry over and over. Beth was raging though and Kairi was certain the balance of power in her fate had changed, for the worst. Beth vanished out of the room briefly. Sven scrambled to get some clothes on. When Beth returned she looked even more angry if that was possible. Beth picked Kairi up and headed off to the bow of the yacht so quickly Sven was stumbling and running to keep up.

"Beth, honey, my love , its not all her fault... I.."

"Its not a she it's an IT. And if you cant stop playing with IT then I will make sure that the temptation is removed.."

"Look, Beth. She goes in a couple of we... Beth... BETH!"

Sven watched seemingly paralysed by shock or guilt as Beth dumped Kairi on her back on a wooden crate at the bow of the boat. Two crew members had been fishing but one look from Beth had them scuttling for cover. 

"Beth. Love. Please honey.."

Kairi watched wide eyed and helpless. Beth's eyes had a wild look which told her she was beyond rational thought. Beth grabbed a wicked looking divers knife. Kairi shook her head no, wishing she could cry out. 

"Beth please, this isn't needed. You have known  about K from the start. Why now, you know she's almost at the end of her deal. It's just some fun. She doesn’t mea..."

"It. It's a fucking IT. Crazy little sex mad bitch. Willing to undergo anything to get a thrill. Well enough is enough."

Kairi flinched as Beth turned back to her, knife still in her hand. Her knuckles were white such was the grip.

"What does he see in you. Huh ? No free will? Freaky magic body? You had good legs I will give you that but you gave those up months ago. It can't be your pathetic flat little tits.."

Kairi flinched. Beth grabbed her left nipple pulling her small breast tight then hacked with the knife. There was a jolt of pain and a treacherous flash of excitement. When Kairi reopened her eyes Beth was holding her left breast in her hand. She had sliced it off!

"If you like her in pieces so much..." Beth raged as she dropped the disembodied cone of flesh and attacked Kairi's other breast just as fiercely. Kairi knew the magic was still protecting her somehow but it was still shocking. 

"Beth be reasonab...."

Sven winced as Beth began to saw at Kairi's neck. Kairi choked and gulped as she felt the serrated blade dragged over her throat through her windpipe  and into her neck bones. Beth shouted in triumph as she grabbed Kairi's severed head and planted onto a nearby post. Kairi could feel it in the back of her throat. But she hadn't finished. Still in a frenzy Beth hacked her way through Kairi's torso, cutting her in half at the waist. She brushed the chest part away and set about the lower half. Kairi had no choice but to watch as Beth set her hips part on its cut end then cut down between where her legs should be. She was sawing her pussy and ass in half !! The sensations were wild. A flood of pain, followed by a crescendo of the magical tingle that got her the closest she had been to climaxing for herself in forever. But then it was over and her lower parts were in two. 

"Lets see you fuck that! " Beth growled . She pushed the two remaining parts aside and Kairi could see that they landed in a bucket of bloody fish scraps the crew had been using as bait, along with the rest of her mutilated body. Beth picked the bucket up and with a triumphant cry tipped the whole lot over the side of the boat! Kairi was horrified. Beth dropped the bucket and slumped to the deck, sobbing gently. Sven ignored Kairi, and instead bent to to comfort Beth, helping her up and leading her back into the yacht, leaving Kairi alone on her pole, sobbing .
