Andy woke with that uneasy feeling that something wasn’t right. He heard the movement beside him too late to react. All he saw was a shadowy figure and the flash of the blade as it entered his chest. The figure moved quickly and slide the blade down Sam’s back before she could stir from her sleep. Sam and Andy lay flat on the bed as the figure moved to switch on the bedside light. He wore a dark hoody, his face still hidden in the shadows of the hood. Two more figures came into the bedroom. They were small and slender, but again wearing hoodies pulled over their heads.

“You can have the man, I’m taking the woman. It has been too long since I felt the pleasure of a female form” said the taller figure as he pulled back the hood to reveal a sweaty, pale bald head with sunken eyes like bottomless wells. This man’s soul has been lost a long time ago.

The smaller creatures moaned as they drew back their hoods to reveal two very strange looking creatures. Probably men, but their sharp faces could have been described as elven if they weren’t so mean looking. They wasted no time in stripping off their clothes and taking Andys skin off the bed. The first one jumped into the hole in Andy’s chest and disappeared down into his legs, his head no longer visible. The second one jumped onto the bed and stepped into Andy’s chest apparently riding on the shoulders of the first one as he slid the rest of Andy over him and manoeuvred his arms into Andy’s. With Andy’s head pulled into place the skin sealed itself and Andy screamed at the intruders inside his head.

“Who the fuck are you and what are you doing?”

“He’s not happy” said Andy’s voice to the bald man. Their accomplice was almost fully undressed, but stopped while he adjusted the handle on the knife and touched the blade to Andy’s head. There was a brief flash of light and Andy fell silent inside his own body.

“That’s better” said Andy’s voice as he stretched and turned towards the mirror to admire his new form.

The bald man finished removing his clothes and picked up Sam. He stepped into the skin and pulled her legs up over his muscular thighs. Once his lower half was completely settled into Sam he sat on the edge of the bed and moved his rough hands slowly up and down her legs. As if satisfied by his new soft skin, he pulled her body up to his chest and slid one arm after the other into Sam. Again, he stopped to caress his new arms and feel Sam’s skin as it wrapped around him. Finally, he pulled her head over his and the skin closed down his new back. He stood and started to reach up to feel his new breasts as Sam spoke calmly inside her head.

“You’re the man form the alley, aren’t you?” said Sam

“I guessed you would be the smart one” said Sam’s voice. “No. Silly me, I am the smart one. I mean look at me, I’m gorgeous.” Sam’s hands felt her breasts and slid down to her pussy where her left hand lingered and explored a little before she stretched out both arms and spun round.

“How did you find us?” said Sam.

“The knife. It gives off a kind of hum when it is used that my little friends can hear if they are close enough. We have been combing the city, street by street each night to find it. We got lucky. I’ve had to look for months at a time for it. You clearly use it a lot, but you haven’t begun to tap into its potential. I’m sure you were aware enough to realise the blade can silence you and leave me to your body in peace. But as you seem rational, I quite like the feeling of your consciousness. As long as you don’t disturb me, I will let you watch”.

Sam thought her best move was to keep quiet and just see what she could learn from this man – he clearly knew the knife’s abilities.

“Now, where was I?” said Sam’s voice.

“You were about to find the sexiest clothes this human has and put them on, so I can rip them off you!” said Andy, almost drooling at the thought.

“Why Andy! What has come over you, my darling!” trilled Sam’s voice. “Alright, as it’s you, I’ll go and find something suitable.”

“Now let me see, where to look? This would be easier if I knew where I kept things. Hmmm, as your one of my better behaved passengers, I think I’ll take your memories”.

Sam’s hands picked up the knife from the dresser and twisted the handle a few times. She touched the knife to her temple and she felt an odd dizziness as her voice said;

“Ooohh. I like being a girl, I do have a fabulous imagination, don’t I. Oh and yes, I think I know exactly what I’m going to wear!”

Sam’s hands opened her lingerie draw and she selected a pair of blue satin briefs, her hands hovering over the matching bra. Her left-hand cupped underneath her boobs as if weighing them. She circled around her right breast and left the bra where it was.

“No, I don’t think I’ll be needing that. My breasts are perfect! Mmmm, that feels so good.”

Next Sam’s hands settled on a satin slip dress and she quickly put it on. Smoothing down the dress and feeling the soft silky fabric beneath his new slender fingers the man came up behind Andy’s body and slid Sam’s hands around his waist and down onto his rapidly growing cock.

“Now, then. Let’s deal with your little problem, shall we?” said Sam’s sultry voice.

“We can’t help it!” whined Andy’s voice. “To be fair there are two highly charged libidos in here, so it should be no surprise we go off like a rocket the first time we are in a new body.”

“I know. Now tuck your arms out of the way and turn to face the mirror. That’s it. I’ll be your arms and hands for the first time and give this cock a nice gentle workout.”

Sam’s slender fingers enveloped Andy’s cock and began to move slowly up and down. Andy’s voice gave a low moan as the creatures inside were brought to the edge of a volcanic release of cum.

Sam’s hands relaxed their hold and eased off to prolong the feeling for the little creatures. Sam thought that this must be a well-worn routine for these three. She felt her left hand move behind her to gently caress her satin covered arse while her right hand re-started the hand-job.

It wasn’t long before Andy’s voice cried out as his cock spurted cum out all over the bedroom floor.

“Oh. You did need to get that out of your system, didn’t you, gorgeous?” teased Sam’s voice.

Sam felt herself being taken over to the bed. As she lay there, fighting the urge to ask questions until this man had enjoyed her body to the full, she wished she could stop her mind racing with wild ideas about what he would do with her. She felt her hands slide down the dress and lift up the hem to explore her now moist pussy. The fingers of her right hand slid inside, and she gasped without being able to stop herself.

“Mmm. That does feel good, doesn’t it?” she heard her voice say.

With a jolt, Andy’s body was on top of her, his cock searching for her pussy. A hand guided it the last few inches and then she felt Andy thrusting deep into her body. The creatures inside Andy managed to coordinate his body well enough to make it seem like he was normal, but occasionally the arms tried to move before the rest of the body was ready and he pitched forward on top of Sam.

The two bodies pounded on each other for hours. Sam was **** to ride one ecstatic wave after another until her body lay flat on the bed, dripping in sweat. Andy’s body fell face down alongside her and immediately began snoring.

Sam fought the tiredness. It must be dawn soon. She had no idea of the time, but she had to stay awake. If there was a chance she could get out of this, it would be when this man fell asleep.

To Sam’s dismay, her body rose from the bed and moved towards the shower. The man took great delight in showering her body, running his hands all over her body as the hot water soaked away the sweat. They moved back into the bedroom. He picked out a silky nightdress and put it on. With a theatrical swirl, he smiled at the vison in the mirror and gave a contented sigh. At last Sam felt herself climbing into bed and settling down to sleep.

Sam waited what felt like an eternity before trying to move her own fingers. She nearly shrieked when they moved to her command. This was it, her only chance. She had to move fast and hope that Andy would pick up where she would have to leave off. She knew the knife was on the dresser, so she slowly and carefully eased her body out of the bed. She reached out her senses to see if the man inside her was waking.

Nothing.

She reached the knife, turned and slid it down Andy’s back. The creatures inside started to wake, but not fast enough as the knife struck twice more deflating them inside Andy. Running on instinct and panicking at the thought of the man waking at this crucial moment, Sam touched the knife to Andy’s back to re-inflate him with the little creature skinsuits still inside, gambling that they wouldn’t be able to do any harm to Andy. As Andy re-inflated she pressed the knife into his hand and drew it down her front revealing the bloated stomach of the bald man. Just before her strength left her, she managed to start to pull the knife back in towards the man who was now waking to the horror of his dream ending so abruptly.

Andy took in the scene and continued the knife thrust into the fat belly. Sam and the man’s skinsuits fell to the floor, one still inside the other. Andy looked around quickly to check if there was anyone else in the room. Satisfied they were alone, he started to untangle the man’s skin from his girlfriend. Once Sam was back to normal she gave Andy a massive hug and slumped down on the bed, exhausted.

“Oh my God! What happened?” cried Andy.

“It’s him, from the alley. It’s his knife! And he has a couple of little friends that are currently inside you. Here, give me the knife and we can get them out of you.”

Andy stared at the skins of the little creatures that were, until a few minutes ago, inside him.

“I had no idea you could just leave stuff inside people. That a bit freaky…..” said Andy

“After everything we’ve done, you find that freaky?” joked Sam. “Alright. What are we going to do with this guy? I didn’t find out his name or anything about him, but I learned a couple more tricks the knife has. If we bring him back, we are going to have to be so careful though.”

“I don’t like the idea of doing anything other than burying his flabby ass, so we never see it again.” Said Andy.

“I know what you mean, but he knows all the secrets of the knife. And while he was wearing me, he did a thing with the knife that gave him my memories.”

“What? So, did he “become” you?” said Andy, concern rising in his voice.

“No, he just knew what I knew. He was mostly interested in where my pants were, but I became aware that he knew everything. My memories were just open to him. Hmmm”

Andy knew that tone. “What are you thinking so I can tell you why I don’t like the idea..?” said Andy.

“Look, if I wear him and get his memories, then there will be no guessing about what it can do. We might even find out where it came from and who he is.”

“OK. But I’m gonna be standing there with this knife the whole time. And I want you sat in a chair or something. No, I’ll tie your hands and feet up before you seal up. And tie your body to the chair. I just don’t want to take any chances.”

“Deal. And we better just record what I say, once I get his memories, so we can write it down later.”

After they had prepared a heavy metal garden chair from outside by chaining it to the bedframe and had two rolls of tape ready to strap arms and feet to the chair, Sam moved the skin to the chair and began to climb in. As planned Andy bound the arms and feet to the chair before Sam sealed up the front. Andy still wasn’t happy until he had roped the body to the chair as well.

“I think you like this bondage stuff” said the man, with Sam wry grin on his face.

“You OK in there?” said Andy, ignoring the quip.

“Yes, he’s keeping quiet, aren’t you? Don’t like the boot being on the other foot, eh?”

“No. I don’t and I won’t tell you anything” said the man in Sam’s head.

“You don’t need to. I saw the memory setting for the knife when you did it to me. Andy. Touch it to my temple.”

“No!” cried the man in Sam’s head.

“Holy shit!” yelled the man’s voice.

“Sam! What’s wrong? What is it?” cried Andy, his hand poised with the knife over the man’s fat belly.

“It’s OK” came the gravelly reply. “This guy is 347 years old. His name is “Chr’Dak”. He stole this knife from a monastery high in the mountains somewhere in Asia. The name in his mind is not anything I’ve come across, he speaks a different language. No, no. I’ve got to focus. The knife. Is it that thing on? Are we recording?”

“Yes” said Andy. “Go for it”

Half an hour later they were done. They had detailed instructions of all the knife settings and there were dozens of them. But no closer to knowing exactly where the knife came from.

“Oh my God. This guy has seen some action around the world. It seems like he stops aging whenever he’s inside a skin, so he’s stolen other people’s lives to keep going. He was getting weak when he made that **** lunge at Beth – he doesn’t normally take on more than one person when he’s grabbing a body.”

“What about those creatures?” said Andy.

“They found him years ago. They can hear the knife and they built up a kind of mutually beneficial relationship. He doesn’t know where they came from. Hey. Do me a favour, please? I want to know if the memories persist outside the skin. Make a small gap in the neck in front, so I can get my head out.”

Andy did so and pulled the head backwards to reveal his girlfriend once more.

“Wow. Gone.” said Sam. “That’s a huge relief. I was beginning to worry that I’d be stuck with him in my head. Do the same under the arms would you?”

Andy hesitated. “This is you, right?”

“Yes. It is. I want to just mess with this body a bit before we bury it in a deep dark place.”

“Definitely you” said Andy as he undid one hand, made an incision under the armpit and pulled the sleeve so Sam’s arm could stick out. Once Andy was sure it was Sam, he did the other side and released her from the chair.

Sam grabbed the dangling arms of the man and tied them in a knot behind her. Her soft slender arms now poking out from a large fat man’s torso, her head perched on top like a doll.

Sam stood up on her muscular legs and looked at the overweight male body she inhabited. Andy kind of knew what was coming next and it wasn’t him. Sam grabbed hold of her junk and started to play with her rapidly hardening cock.

“Wanna try?” she said playfully to Andy.

“You are definitely on your own with that one.”

“Just want to see what another cock feels like. It’s kind of fun being this overweight and male.”

Sam started sliding her hand up and down her new cock with a far-away look on her face. She started to moan as her hand eased up and down the shaft. When the inevitable happened, she threw her had back and shouted “Yes! Oh yes! Oh, man that feels awesome!”

“Happy now?” said Andy who was still tidying up the chair and strappings.

“Mmmm. Yeah. That was good.”
