A Few Days in my Sister's Body

Two things became immediately clear upon waking, the first was that doing first time anal with a long cock and minimal lube while drunk and with no preparation leaves your ass hurting like a motherfucker once the drink wears off. The second and much more urgent thing was that I felt like I was suffocating.

My eyes shot open but I could see nothing but a flesh coloured blur and a weight crushing my chest and head and with a bit of difficulty I was able to extricate myself from what turned out to be Mike's arm. At some stage in the night he had either made his way into bed himself or the guys had put him into bed before leaving, now that I could see again and looking at his naked belly rise and fall with the roars of his snoring I would guess the former, I couldn't picture his two friends stripping him for bed.

I stretched my limbs with a yawn and could feel dried cum flaking off my ass and inner thighs, another reminder of last night, and used the blanket to lazily brush myself clean. I could tell when I'd gotten most of it from the light streaming into the bedroom from around the curtains and all too slowly it dawned on me what that meant, I had fucked up. It was morning already and that means I've wasted my time to delete the blackmail by sleeping in. I had to think quick, my own phone wasn't beside the bed to check the time I must have left it downstairs somewhere but I could see Mike's on the other side of his pillow, if I could reach it I could delete the video and any pictures and be home free. That was easier said than done, Mike's bed was against the wall on his side and he was on his back beside it, the only way I was getting that phone was by reaching over him.

I got up onto my knees and steeled myself, holding my breath and stretched for the phone. Despite nearly putting an entire tit in his mouth and silently cursing my huge breasts and short arms I was able to reach the phone without Mike and thankfully he had face unlock turned on so within seconds I was in. The first thing I noticed was Mike had two unread messages, both from the guys describing how much fun they had, what a good hostess I was and asking for another invite real soon, Ryan's being much less subtle and was full of innuendo which made me grin. Next scrolling through his camera roll and for a man who was usually so unkempt and messy his pictures and videos were immaculately organised, he had all of his photos separated into folders based on their subject. There was obviously one named 'Kim', I scrolled through and confirmed that the video and all of the hidden camera pics were in there but I also found a couple of years worth of creep-shots of Kim sunbathing or working out in the garden, clearly taken from an upstairs window overlooking our yard or what looked like a gap in the fence. I deleted the entire album but scrolled through the others out of morbid curiosity to see who else he had been creeping on, there was a folder called 'In the wild' that seemed to be pictures of women's asses and cleavage that he had seen out and about in stores or on transit. There was another folder dedicated to my mom which was mostly pictures of her in sunbathing, in the pool, in our hot tub but in a couple of the more recent ones it looked like she was posing. There were a couple where she was staring straight at the camera as if she had known he was watching through the fence, peeling down her bikini to expose her breasts to him and a couple from only a week or so ago where he was clearly in our house with her, mom bending over a table or sink and flashing a thong. The image of Mike standing over my own mother with his cock in her mouth flashed into my mind and I shuddered, quickly swiping away and deleting that folder too.

Mike began to stir as I kneeled beside him in the bed and my heart stopped, I was running out of time. Fumbling for the settings I checked if the pictures were backed up anywhere and...jackpot! iCloud backup was turned off, I'm in the clear! Just need to get the phone back into place so he doesn't suspect anything until I'm safely at home with the doors locked, if he tries anything then I can call the cops and once I get my body back and Kim is away at college I can deal with him properly. I reached to put the phone back in place but this time I was rushing, I lost my balance and landed sideways across Mike's chest.

"Huh what the fuck." He mumbled, half asleep and with a dry throat, no doubt hungover to boot.

I scrambled for an excuse and quickly defaulted back into girlfriend mode.

"Hey sleepy head, good morning how do you feel?"

"Like ten pounds'a shit in a two-pound bag, what are you doing?"

He was starting to wake a bit more and was looking right at me confused and a bit suspicious, I needed a distraction before his thoughts could catch up with the situation and did the first thing that came to mind. I grabbed his morning wood and started gently stroking.

"I just felt lonely waiting for you to get up, you know?" His cock was rock solid now and he reclosed his eyes, the hand job seemed to be working to keep him off balance. "Last night was a lot of fun, I think your friends liked me."

"Maybe a little too much, Ryan especially seemed to have his...Jesus girl go easy I'm fragile today." I didn't like the route his mind was going down, I needed to keep him in a good mood to float the idea of letting me go home for a while so I gave his balls a little tug to derail his train of thought. "What was I saying? My head is fried, I don't remember a damn thing from last night."

"Well you were winning a lot of money at poker, I was very impressed." I let a string of drool fall from my lips onto the head of his dick in as sexy a way as I could manage and used it for lube, he responded with a groan of pleasure. "Then the guys had to leave so we showed them out, then you fucked my brains out again." I gave him a tighter squeeze which made him jump a little. "Then we came to bed."

"Hmm I remember winning at poker alright, some other stuff is coming in flashes." He absentmindedly grabbed and started kneading my ass which caused me to wince. "What's the matter with you?" he said, eyeing me. I scrambled for an excuse.

"Umm I'm just a bit fragile myself, you don't remember fucking my ass all night? You were amazing but I'm feeling it today."

"I remember hearing you screaming to fuck your ass but the memory sounds distant, and you said we went to bed afterwards? So why did I wake up in the hallway in the middle of the night?"

Fuck I'm losing control of the situation, time for a different tactic.

I started crying.

Well I tried anyway, I turned my head away hiding my face with my hair and made my best attempt at a fake cry. He was a middle-aged divorcee borderline alcoholic not the Oscars judging panel so it didn't need to be award-worthy but I found the more I drew from thinking over my current situation, being used and abused for pleasure by multiple men over the last few days as much as I enjoyed it in the moment and the literal pain in my ass as a result of last night the more real the emotion became and actual tears soon started streaming.

"Ah shit don't start-" he began, his face showing annoyance and awkwardness before I cut him off.

"I knew this would happen you're just like the rest of them! You started off nice, taking care of me when I had a horrible day then you blackmailed me. Then you treat me nice again, you bought me a nice costume and I had fun with you and your friends and just as I'm starting to enjoy your company and think this could turn into something real you start looking for reasons to be mean again!" The tears might have been real but the rest way grade-A bullshit and I was just throwing out the first nonsense that came to mind, I was hoping the emotion would put him off balance enough not to read too deeply into the words. His face turned from annoyed confusion into worry at that last part.

"What do you mean real?" He was sitting up now and watching me over his gut with a look of concern, it was now or never time to see if I could stick the landing.

"I might not be very bright. I know most men only want me for my body," I cupped my breasts to emphasise my point and distract him, "and I know we started off under strange circumstances but you make me feel good and you treated me nice yesterday and I thought I could get used to a life like that but I guess you're not different after all..." I looked down and away, letting the hair fall over my face and trying to look meek and small. Inside I was cringing at the crap falling out of my mouth, surely he wasn't this gullible. I felt him shifting in the bed and then he was pulling me into a hug, kissing my hair and using one of his huge hands to wipe the tears from my eyes.

"I do wanna treat you right baby I didn't know you felt that way, please gimme another chance. I only tricked you because I needed to have you, I haven't felt this way about a lady since my ex-wife." This was it, I looked up at him trying to make my eyes big.

"You really mean it? We can try this the right way?"

"Damn straight, I wanna make you my lady."

"Oh Mike!" I exclaimed as I threw my arms around him.

Aaaaand scene, I'd like to thank the academy, etc. Turns out when a sexy teenager with big tits that you've been blackmailing says she wants to be with you logic takes a back seat, now I can see why guys fall in love with prostitutes who tell you what you want to hear. His penis was still hard somehow and was now pressing into my belly trapped between us and my train of thought completely surprised me. Now that I had him where I wanted him I just needed to make an excuse to get home and then I was free, no blackmail means no leverage I could lock the doors and wait for my family to get home and if he tried anything the cops were a call away and if he went to jail it would solve all my problems, I wouldn't have to figure out what to tell Kim. Maybe I was in this body too long but I was starting to feel an emptiness inside and the thought of one more fuck was tugging at the back of my mind. He was no model by any means but I can't deny the feeling of fullness whenever he was inside me, like his cock was perfectly sculpted for my pleasure. My nipples hardened against his chest in response and I could feel him shift the weight of his cock against me and the precum drag across my belly as he did. It didn't take much to turn me on these last few days, I wonder if this is how Kim feels all the time. I reached between us and ran a finger along my slit, it didn't need any warmup it was ready to receive. I looked up at Mike and ran my tongue along his jaw to his lips which he eagerly received.

Even after the kiss broke we didn't say anything, I just looked at him with lust-filled eyes and pressed my hands against his chest, pushing him onto his back and throwing a leg over to straddle his waist. I pulled my hair out of the way and kissed him again as he took the cheeks of my ass into his strong hands, the pain of last night forgotten for now as I ground my clit along his thick shaft. I couldn't wait anymore, I sat upright on him and raised myself up taking his cock in one hand and guiding it towards my waiting warmth. I took one last look at it, standing like a magnificent throne, and claimed my place.

If it was going to be my last taste I wanted to savour it, I lowered myself onto the head and felt it split my folds as I consumed it. Slowly squatting lower, clenching my walls down on the thick shaft and gasping as I felt the thighs against my ass as I bottomed out. Maybe it was because I was so much more present and wanted to make the most of the moment but it felt even bigger, the angle perfectly penetrating seemingly deeper than ever before. I put both hands on his stomach and started slowly moving up and down along his length, taking in the look of bliss on Mike's face for the last time, then grabbing his hands and raising them to my tits. He took them eagerly, mauling and pinching and slapping in that rough way that I'd become addicted to as I increased the pace, bouncing now as the slap of his balls and thighs against my ass was ringing out into the room.

"Feels like I'm still dreaming," he said in between ragged breaths, "you're like an angel."

I slowed right down at that, stopping at full mast and grinding down against him.

"Hey don't sto-"

"Save that sappy talk for later," I said sneering down at him, "call me your whore, treat me like a little slut old man."

He looked taken-aback by the change in attitude, for a few seconds he looked at me with surprise while I ground down against him and played with my clit, not breaking eye contact. Then it was like something switched in him, his eyes flashed with an animal lust, his mouth turning to a snarl. He reached up and grabbed both sides of my head, pulling me down towards him and wrapping a fist into the hair at the back of my head.

"Don't have a heart attack now big boy." I grinned.

"I can't keep up with these mood swings of yours," he growled into my ear in a playfully angry way, "but if I gotta fuck the attitude out of you I'm gonna enjoy breaking you in." He reached his free hand back and slapped my ass so hard the noise left a ringing in my ears.

"Punish me daddy." I whispered, an excited squeal bursting out as he cracked his hand against my ass-cheek again.

He didn't need any more encouragement, his hands moving to my hips and lifting them up along the length of his cock until the tip almost escaped before slamming me back down, the full length of it slamming deep and fast and nearly knocking the air from my lungs. He kept that pace for a few minutes, slamming me down into him as his breaths turned into animalistic grunts and his face was turning red from exertion. For me it felt incredible, he was hitting pleasure spots I didn't know existed at such speed that all I could do was gasp in air between thrusts that escaped each time I was slammed back down. It felt so good I could feel the now familiar white blankness covering my mind, a sign of the incoming orgasm that removed all possible intelligent thought. Through the haze I could hear myself whimpering, begging through noises for the finish. It was only seconds away and as the orgasm rolled in my whole body tensed up, the bliss removing any thought as my muscles twitched and vibrated through the incredible pleasure.

"Acting like a brat then cumming without daddies' permission? We'll have to make sure you're punished for that."

With my muscles spasming involuntarily, I couldn't react when he threw me off his dick face down into the bed and started mounting me. He quickly pushed his way back into my pussy and continued his assault, the force of his thrusts crushing me into the mattress. My mouth hung open and I could feel drool escaping alongside my moans with each pounding thrust.

"This ain't no punishment at all for a little slut like you is it?"

"No daddy, I want it, I need it."

"What do you need? Tell me." His pounding was relentless but his breath was starting to catch now as he spoke.

"I need your cock, I love it, I want to be used. Let me be your sex toy, I'm addicted. I'll do anything you want if you keep fucking me so good." I don't know how much of it will still be true in an hour but for now it made the sex feel even better, it felt so good to admit to being a slut right now and the more I admitted the closer I could feel a second orgasm approaching.

"I'd never let my girl go without," He put his hand on the back of my head and forced it into the mattress, "but now it's my turn." His thrusting got desperate and I could feel the muscles in his cock flexing.

"No wait baby I'm close again." I tried to say but it came out muffled.

He never changed his pace, if anything it got faster and a few thrusts later he was screaming out in pleasure. His dick flexed and pulsed as he emptied his load inside, it felt like a flood and I could feel it deep inside as each spurt fired. He kept me pressed down into the bed as he caught his breath, I could feel his balls twitching against my pussy as he drained the last few drops. I didn't get to cum a second time but it was almost as satisfying to feel his orgasm, his seed filling me up. He started to pull himself free and I could feel some of it starting to leak out of me, as far as last fucks go it was an enjoyable one with some room for improvement.

"You're a wildcat when you get in the mood darling." He had pulled out and collapsed down beside me on the bed, wiping the sweat from his forehead.

"I'm full of surprises." I winked, stretching my now stiff muscles.

He reached over to kiss me and for reasons completely unknown to me I let it happen. It wasn't as gross as it had previously been, in the moment it just felt appropriate and a little nice, like a tiny touch of aftercare I didn't know I was waiting for. We made out and held each other for a minute until the urge to pee became too strong.

"I gotta pee, do you have anything I can wear?" He reached over the side of the bed and threw me a tank top that was far too stretched, it was long enough to cover my bottom half but the straps hung down enough to barely cover my nipples if I wasn't careful.

"Make me a coffee while you're up will ya?" He turned back over and started scrolling through his phone, scratching his balls with his free hand.

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

I finished up with the toilet and did what I could with water and tissues to fix the mess that was my makeup and to clean up the mess that was still oozing out of me. As I was walking to the kitchen thinking about how desperately I'd need a shower later I passed a door left ajar that had some glowing lights coming from inside, curiosity got the better of me and I crept inside. It was a fairly small room that seems to have been skipped by the previous day's cleaners, there were old take-out containers and cans of beer strewn across the floor and on the desk which also contained the source of the glowing lights, Mike's computer. I was admiring the PC setup, I would have never pegged Mike for someone with a powerful home build, when I bumped against a plate that rocked the mouse bringing the screen out of it's sleep.

It hadn't been locked so it opened directly on the desktop and I was greeted with the sight of my own face, it was the snap of me smiling and exposing a tit to one of the hidden cameras yesterday when I was getting rid of them. My mouth fell open and I shrieked as I felt an arm wrap around me from behind grasping at my chest as Mike nuzzled into my neck, I hadn't heard him come in and it nearly made me jump out of my skin.

"That's one of my favourites." he said, pawing at my tits.

"I didn't know you kept these on your computer." I said, my voice came out much higher pitch than I expected.

"Good thing too, can't trust this damn phone a bit I can't find any of 'em this morning."

"Hey maybe we should get rid of them though right? We can take some new ones together we both like? I'll even model for you." I turned around towards him and he shifted his hands to my ass, continuing his assault on my neck and ear.

"No way I'm getting rid of these I'm keeping them just for us, they'll be a funny story to look back on in a few years."

"But I'd really like them gone baby, we don't want anybody else to see do we?"

"I said no," he pulled away from my neck and was suddenly looking at me with anger and suspicion, "you still think I'm gonna share this stuff of my own woman? You calling me a cuck?" His quick switch to anger scared me and his grip had gotten painful, I threw myself into him and started kissing his neck back.

"No of course not baby you're right I'm sorry, forgive me?" He looked down at me with suspicion still but the anger was starting to fade, he nodded and I went back to kissing his neck and cheek for a few moments before insisting on going to the kitchen to make him the coffee he wanted. As I left he sat down in the chair and watched me go, the anger mostly gone from stare.
