A Few Days in my Sister's Body

I had every intention of making this day three but the more I added the more I felt it needed it's own entry to finish the night and set up the next day, sorry! I promise the next entry is day three and it shouldn't be as long a wait.

----------------------------------------------------------------------------------------------------------------------------

I'm making a habit of waking up outside of bed disoriented. The fact that both times I've had one of those mind-blowing orgasms it's knocked me out cold is becoming a serious problem, so far it's only happened at home but if it was to happen somewhere else or god forbid in public...

The thought made me shudder.

Time to take stock of the situation. Opening my eyes and peeking through the open curtains at the sun starting to get a bit lower, it seems like I've been asleep for a few hours. My phone confirms it's already nearly 7 o'clock so I've lost most of the day.

As I'm stretching out my back and yawning I can feel and see flakes falling from my face and tits, dried cum crumbling off me like dandruff. That piece of shit didn't even clean me off.

A thought occurred to me then, Mike finished in my mouth just before I passed out but so far that hot horny feeling isn't occupying my brain. There must be a sort of cooling off period, I guess it makes sense since you could end up getting trapped in some sort of a fuck-loop. Small miracles I guess, maybe I can still salvage Kim's reputation and deal with Mike before she gets home.

Now that I think of it, Mike was waiting for me when I got home and talked to me like we were a couple, what the hell is going on in his head? He's always been a perv and not the brightest but surely he doesn't think us fucking when I was desperately horny makes us an item? The idea of playing happy families with Mike in his filthy hoarder's house, servicing his cock while he gets wasted makes my skin crawl.

I got up and crossed the room to close the curtains, noticing Mike's beat up car wasn't in the driveway next door with relief but didn't notice Mr and Mrs Jones from up the street on an evening run. Still in a bit of a stupor from the sleep I forgot I was standing naked in the window until Mrs Jones realised what her husband was staring at and smacked the back of his head so hard he nearly fell. I grabbed the curtain to hide myself giving an apologetic smile to Mrs Jones' angry glare and then yanked them closed. I sighed walking back to the couch and grabbed my cum stained gym wear from the floor on the way by. It smelled musty but there was an enticing sweetness behind it that must be from the bodyswap side-effect. I could start to smell it on myself and decided a bath was more than necessary, making my way into the laundry room to throw the clothes in on the way upstairs.

While the bath filled I had a look through Kim's room for some clothes, after the past two days I desperately need some comfort and it's a pretty humid night, I decided on a loose pair of shorts and heading to my own room I grabbed my favourite Smashing Pumpkins T-shirt. It wasn't exactly tight on my own body but it looks comically oversized on Kim's. Mom and Kim have the bathtub lined with products that I just didn't have the energy to examine too closely but I recognised a bath bomb I had given mom as a present for her birthday a few months ago and I guess if she hasn't used it by now she probably won't miss it. Once the hissing of the bath bomb was done and the water was now a strong lavender-scented purple I climbed in and let the bath work it's magic.

I didn't realise how tense and sore my muscles had gotten, I guess I'd overworked my new body a bit and dropping weights on myself was a contributor. The relaxing salts of the bath bomb soaked into my skin like a dream and after a while I realised I should probably wash. I took face cloth from the shelf beside the bath and started rubbing it into my perky breasts, removing flakes and globs of cum that had rehydrated in the water. Thankfully it looks like the bite marks around my nipples from Mike was already fading and the slaps from Chet hadn't left a lasting imprint.

I wonder why it is that when I'm in a horny frenzy like that I actually enjoy the pain, it's not something I like in my own body. Maybe it's Kim's body responding like it does with her sensitive nipples, maybe the longer I'm in her body the more her own kinks are starting to affect me...Maybe I shouldn't be thinking about my own sister's sexual kinks. As if to wash the thoughts away I dunked my head under the water to wash my face. Holding my breath under water reminded me of Chet forcing his cock as deep into my throat as he could go, blocking my nose and choking me until I saw stars. As I felt my body start to panic I realised I had snaked one hand down between my legs and was slowly rubbing circles around my clit.

I slowly pulled my hand away and surfaced with a deep breath, pushing my hair away from my face. Even without a dose of cum, am I just a horny person or is Kim always this horny? She's never seemed like a slut or anything, only had a couple of boyfriends and seems like a perfectly normal late teen but maybe her hormones are going nuts after going on birth control. That reminds me I have to take another pill today before I forget.

I finished washing up, towelled off my hair and body and put on the comfy clothes I had laid out and took my pill. I didn't bother with a bra, I'd rather not waste time messing around with something that would feel uncomfortable after a while but did find a very silky pair of pink panties that felt amazing against my skin. I started down the stairs and the smell of Chinese food made my stomach rumble but my mind panic, who the fuck was in my house? I got to the bottom of the stairs and peered around the corner into the kitchen, it was empty of people but there was a bag of Chinese takeout sitting on the counter alongside some other bags from a clothing store at the mall. I inched closer into the room and but somehow didn't hear the steps behind me.

"Honey I'm home, I brought dinner."

Before I could react he had wrapped his arms around me at the waist trapping my own and nearly lifting me into the air to plant a kiss on my cheek.

"Jesus Mike are you trying to give me a heart attack, what are you doing?" I yelled, pulling down my shirt that had gotten messed up.

"Hey now, that's no way to greet your man, I was expecting something a little more like how you was earlier." He said it with a wiggle of his eyebrows that betrayed the mock hurt he put into his voice.

"Oh no hey listen Mike we really need to talk about that, that was just a mistake you see-"

"And I suppose yesterday was a mistake too, actually I think I remember making youmistaketwice." he interrupted, stepping forward with a wry grin.

"That was, look I...I wasn't..." I sputtered. I hadn't worked out a plan to get out of this yet and it looks like my brain wasn't gonna bail me out on the fly here. "Look we had a bit of fun and you fulfilled a need but this can't work, we can't be a thing you know that."

"Oh I know all about your needs." he said, stepping forward again. I tried to step back but found myself backed against the kitchen counter, his gut pressing against me and gently pinning me. "Come on now girly I've seen the couple of guys you've brought home, twiggy arms and little dicks. I'll admit I've peeked in your window a few times to get a good look at you at work and I ain't never heard you make noises with them like you did with me." he reached down and grabbed the hem of my shirt, toying with it a raising it slightly.

"I'm sorry ok but no, this can never happen again." I said, ducking away from him. He initially didn't let go of the shirt and it lifted up exposing my midriff for a second until it slipped from his fingers. My mind was reaching for anything that could finally convince him to leave me alone. "Besides, you're like 20 years older than me and if my dad found out he'd kill you."

Mike stopped and stared for a few seconds but the grin never left his face, he reached into his pocket and pulled out his phone. It was a bit marked and the screen was cracked in one place but when it unlocked it opened on a still frame of our sitting room.

"Well it's a damn shame, I thought we could have some good mutual fun with each other but I ain't stupid." he said, starting to scroll through what I know saw was a video. "I got me some insurance. At first I just wanted to get a confession, some proof that we fucked yesterday to hold it over you but I ain't never thought you'd come home hornier than a hellcat. Which one of us you think your daddy is gonna kill when he hears you got a new daddy?"

"-thers couldn't make me feel like this, only your cock can make me feel better. Please make me feel better daddy!"Mike had hit play and Kim's voice, my voice, was passionately crying for release."Fuck me daddy, yes daddy I'm so close!"

On the screen my ass was bouncing hard up and down in Mike's lap, the sounds of skin slapping, heavy breathing and my own desperate begging coming through the small speakers but in my mind it might as well have been booming through a loudspeaker. My mouth felt so dry, my knees were weak and I nearly buckled when Mike moved beside me and threw and arm over my shoulder, his meaty hand resting on my left breast.

"Don't you turn away now, this is my favorite part."

-cum for daddy."I watched as the agonisingly horny girl in the video, me, nearly collapsed off Mike's cock. My body vibrating in ecstasy as I snapped backwards, my head lolling back in perfect view of the camera which caught an upside-down shot of my eyes rolling into the back of my head, mouth agape whining through the orgasm. Then Mike lifted me off him and back against the couch where he covered my face top to bottom in his cum which dripped slowly off my contented smile.

He hit the power button to lock the phone as the smaller version of himself in the video started walking toward the camera and in the black mirror of the phone was my own pale face staring back. He gave my tit a rough squeeze which snapped me back to reality.

"Now this can go one of two ways. The first is you do me a few favours; we have some fun and play happy couple for a few days and I'll delete the video. The second option is you kick up a fuss and I send this directly to your daddy and we let him decide what to do with you." To punctuate he scrolled through his contacts until he hit "Next door future cuck" and started a new message with the video attached.

"No please dont!" I begged, reaching for the phone. He held it up out of reach but his finger hovered dangerously over the send button. "I'll do it, whatever it is just please don't send it."

"Now there's a good girl, have I told you before how pretty you are when you beg?" Triumph crossed his face, if his original plan was just to get me to admit we had sex on video then it's exceeded his wildest expectations. "I've got big plans for us Kimmy just you wait. Who knows, by the end of the week you might just find you like it too much to stop."

I sagged, defeated. "You promise you'll delete the video if I do what you ask?"

"Scouts honor!"

I have no reason at all to trust him but no other options either, I'll have to play the good girlfriend role until I can find an opportunity to delete the video.

"Well what sort of plans did you have in mind?"

"Plenty of time for that don't you worry, in the meantime let's get you some girlfriend practice. I got us dinner and it's getting cold, a good girlfriend would show some appreciation." He gestured at the Chinese takeout on the table.

"...thanks" I muttered.

"You don't sound very grateful?"

"Thank you." I spoke, a bit louder.

"Thank youhoney, or you can use baby or daddy or any other lovey nicknames you want."

"Thank you, honey." I said, the words dripping with insincerity.

"That's something we'll work on, a good girlfriend would also give her man a thank you kiss." he pursed his lips and made kissing noises at me.

Gross. Hesitantly I leaned forward, preparing mentally to give him a quick peck. As soon as I was in range his hand wrapped around my back and pulled me into him, his tongue penetrating my closed lips as his hand dipped down to get it's fill of my ass cheek. All I could do was squeeze my eyes shut and wait for it to be over. Briefly I realised that this is the first time I've kissed a man without being frenzied by cum. The scratchy stubble was a weird sensation and even being the fact I was towered over made me feel small and vulnerable.

He finally broke the kiss after what felt like an age, licking his lips as he backed up and reluctantly removing his hand but not before giving a few final squeezes.

"That's a bit more like it, could use some more enthusiasm but we'll work on that. Now be a good girlfriend and plate up my food, I'll take it in front of the tv." With that he took off to the couch, turned on the tv and left me standing there feeling stupid.

Ok breath, let's think for a second, take stock. Playing the dutiful girlfriend is humiliating and there's not a doubt in my mind he's going to want to keep this PG. On the other hand I have no choice, if he sends that video anywhere Kim is in big trouble and if mom and dad find out what I've gotten into I'll be dead meat. Maybe I should play along, try and trick him into thinking I'm enjoying it and then when his guard is down I can steal the phone. It's going to take some serious acting to seem like I'm not repulsed, I guess if worse comes to worst I could dose myself with cum. That would get rid of my inhibitions and get me through sleeping with him at least.

"Come on now Kimmy don't tell me you've changed your mind, I wanna eat with my favorite show." he drawled petulantly, didn't take him long to fit into the deadbeat husband role.

"I'm coming!"

"You're comingwhat?"

"I'm coming...dear." I said rolling my eyes.

He snorted and seemed to go back to his show. I grabbed a couple of plates and threw the food onto them haphazardly before bringing two inside and dropping them on the table in front of the couch. I moved to sit at the far end but felt myself held back by the back of my shirt.

"Come on now and snuggle up." he said, tugging my shirt back.

I fell backwards into the seat beside him as he reached forward and started tucking into his meal. He eats like an animal, grabbing fistfuls of food and forcing them into his mouth, often missing and having crumbs and pieces fall down the front of his shirt. It was almost enough to put me off my own food but my stomach rumbled and I hadn't eaten since breakfast. While I worked through my own plate I checked out the show Mike was watching, it seemed to be one of those budget Game of Thrones clones that all came out when it picked up popularity but they collectively decided not to copy the storytelling and instead the lesson they took was that sex and violence sells. On the screen a slave girl was trying to seduce some sort of high-level guard to steal some prison cell keys and beside me Mike had finished his plate and thrown it back down onto the table with a belch, his eyes fixed on the upcoming sex scene.

"You oughta watch what you eat Kim we don't want you getting fat, my ex-wife let herself go, you wanna keep your tight little body like hers." he said gesturing at the TV with one hand and scratching his own fat belly with the other.

On the screen the soldier had realised what the slave girl was trying to do, spun her around and was preparing to take her from behind as punishment. I put my plate down; I had mostly gotten my fill but being near Mike's slobbish actions was putting me off eating anyway. I settled back to watch the rest of this trashy show hoping it would end soon and I could try and kick him out for the night. As the guard shackled the slave's hands behind her and entered her roughly I looked over and Mike was idly toying with his growing erection through his pants, not taking his eyes off the action.

"I shouldn't be doing this myself no more, come on darling gimme a hand and I might have some desert for you." he put one hand around the back of my head and started pulling it over to his crotch, his other hand peeling down his pants as his almost fully erect cock sprung free.

I put my hands on his thigh to resist but he's a lot stronger than me. "Listen Mike, please I'm not really in the mood and I'm pretty full from dinn-"

"What kind of girlfriend denies her man's needs, I don't give a shit how you do it just get me off woman." he released my head and took my hand now, wrapping it around his shaft.

I had gotten turned around trying to resist putting my mouth on it and now I was lying sideways on the couch with my head against his right side dangerously close, my right hand starting to work up and down the head of his penis. He kept his eyes on the TV but his right hand grabbed a handful of my breast and he started kneading it with his fingers, letting out a satisfied grunt.

I kept my own eyes on the TV too, I'd rather watch the sex scene than stare into the cyclopean eye of Mike's massive cock as I pumped away at it slowly. The more I watched the more the scene actually started to turn me on, the raven-haired slave girl had incredibly huge tits that looked mesmerising rocking back and forth as she was being rammed from behind by a man whose body looked like it was sculpted by the gods. The show looked pornographic at this point, they showed a close up of the soldier's massive shaft sheath and unsheathe from the slave girls dripping pussy as his heavy balls slapped against her. Her moans and cries flooding from the speakers reminded me of my own from Mike's video as memories from yesterday of Mike fucking me from behind caused my own clit to throb.

Fuck it if I have to get him off anyway I might as well get something out of it. I slipped my free hand down between my legs and felt my own wetness, easily slipping my middle finger in and using my thumb to massage my clit. On screen the fucking was picking up speed, I matched that pace on Mike's shaft and could hear the difference in his breathing as he started letting out low grunts that signalled his fast-approaching orgasm. We were in a race to finish now and I was behind so I threw all subtlety out the window, I raised one leg giving myself easier access and started to fuck myself on my fingers faster. That finally pulled Mike's attention from the TV, from the corner of my eye I could see his head turn toward me but I kept my eyes on the show. That must have tipped him over the edge and I could feel from the pulsing of his shaft I was about to lose the race, his breathing became ragged and he started pumping his hips, fucking my hand. In his aching need to finish he inadvertently increased his grip on my breast causing me to gasp and in response I gripped his shaft tighter, furiously pumping it's length.

The grunting piqued and Mike let out a prolonged series of satisfied sounds as he continued to pump his hips through his orgasm, I took my eyes off the screen to see the first stream shoot wildly toward me and onto my shirt along with the second streaking across my waist and legs. I tried to control the direction but Mike's thrusting made it difficult and the last few strands fired across the table onto my food, across the couch cushions and finally onto the floor.

My own finger fucking slowed while I redirected his stream but once it had subsided, I went back in search of my own orgasm. Two of my own fingers curled inside while my other hand maintained its grip on Mike's cock, warm semen slowly running down my fingers as it pulsed. I closed my eyes and imagined myself in the slave girl's place, the guards long thick member giving me the full feeling I'd come to love over the last two days as his hips slapped against my plump ass.
