A Tale of Two Sisters [MfF][Oral][Anal][Incest][Mdom][Mast][Fictional]

**Ok so this is a long one. Please let me know if this would be better presented in multiple parts**

It was rather generous of my friend to let me crash at her place while I visited, more than I imagined she would allow me, especially given our history. Last time she visited me, she begged me to fuck her, and was met with my rejection of her advances, followed by me stroking my cock over her face, and leaving a mess all over, without even giving her a taste. It was a strange period of my life during which that encounter had occurred, and the weeks following were not much better. I enjoyed turning her into my own personal submissive little cock hungry slut, getting her to send me lewds whenever I pleased, and degrading her, making her watch whilst I stroked my cock to pictures of her sisters instead. Suffice it to say, I was surprised she still wanted anything to do with me.

The first evening I stayed was civil, and she was a lovely host. She cooked me a delicious dinner, and we sat by her heater in the lounge and chatted for a while. I laughed off her flirtatious comments initially, until she, now a little intoxicated, became a little aggressive about why I masturbated to her sisters instead of her. Trying to a polite house guest, I attempted to de-escalate the tension, however her detailed recounts of how I had made her watch me stroke my cock and cum on pictures of her sisters, had awoken the beast within. Feeling my cock swell and stretch my underwear, I stood up, and told her I was not in the mood for this fight with her, but that I was going to the room she had made for me, to jerk off to her sisters. Closing the door behind me, I jumped into bed, with a jolt of guilt now kicking in. She had been such a gracious host, and I wasn’t sure if she was just drunk, or actually upset at me. The guilt had killed my erection, so I decided to get changed and sleep it off.

Morning came, and given I was on holidays, I decided to sleep in. The weather being so hot however, and the window facing the morning sun, I was soon too warm to stay asleep. Being such a comfortable bed, and laying under the sheets in just my sleeping shorts, and the vague memories of what had occurred the night before had me feeling a little dirty. I checked my phone and saw it was nearly 11am; it had been quite a sleep in. I wasn’t sure whether my friend was still home or not, but I definitely felt in the mood to just laze in bed and jerk off for a while. I thought I’d be a bit adventurous, and opened the door and walked out into the hallway wearing just my shorts, now quite tented with my morning wood. The house felt quiet, and I could see her bedroom door was slightly ajar down the hall, her bed made, and with no signs of movement beyond. I walked to the kitchen and found a note she had let me, “Gone to lectures, be back later. There’s food in the fridge. Have a nice day!” Once again, this reminded me of what a gracious host she was being, but also perhaps indicated she wasn’t hung up on our argument the previous evening.

I made my way back into bed, making sure to leave my door open, whipped off my shorts, and opened up my laptop. I made sure to position myself in a way that anyone walking past the door wouldn’t miss the mischief I was up to. I wanted her to catch me jerking off in her house when she got home from her lectures. After scrolling through lewd subreddits and stroking myself for about half an hour, I had worked myself up into quite the filthy mood. I decided to open up videos saved on my laptop, of me making a mess on my friends face, whilst also having a tab open with her younger sisters Instagram page. I found a picture of her 18 year old sister in a dark blue polka dot bikini top, barely holding in her huge tits, tongue out, ready for my cock. I stroked furiously, feeling filthy at watching my video of giving my friend a facial, whilst having a thirst trap picture of her little sister, laying naked in her bed, thrusting my throbbing cock up into my hand, grunting and moaning loudly, all with the door open, ready for her to walk in on me.

Suddenly, there was a noise at the door; my fantasy was coming true. I went quiet at this, wanting to pretend I hadn’t heard her get back home, but continuing to stroke my cock, and making sure me and also the laptop screen was in clear view from the hallway. The clinking of keys was followed by an audible thud of the closing door behind her, and then by footsteps heading towards her room, past my open door. My heart was thumping with excitement, ready to be caught being the filthy perve that I am. The footsteps neared my door, and slowed to a halt, followed by a voice mumbling, “That’s weird. Hello..?” I was a little confused myself, as I didn’t recognise the voice, subconsciously slowing my stroking, and feeling my cock twitch in my grip at the reduced attention, waiting in anticipation as to what was about to happen. The footsteps shuffled forward, as I noticed the cautious movements at the door, followed by a young girls face peeking around the door. I froze, as my eyes met with the gaze of a young curious blonde with curly shoulder length hair; it was her younger sister, Izzy.

The room fell silent, with Izzy standing at the doorway, frozen still and what she had walked into, and me, frozen with my engorged cock in my hand, pointed at her, laying on her sisters bed. I watched as her gaze moved down slowly from my face, down to what has happening below, her expression of shock deepening, and her mouth opening wider. It wasn’t until her eyes then moved towards my laptop screen, with a looping video of her sisters face getting plastered with the stranger’s cock that was now throbbing right in front of her, next to which was an image of her in a bikini, that she let out a yelp to express her shock at the scene in front of her.

“Whaaa, Whoo, Huuhh-”
“I’m your sister’s friend, she’s letting me stay!” I yelled out urgently, to try and calm her down and not freak out and think her sister’s house had been broken into.
“Oh..,” she replied, somewhat reassured by this. I had never met Izzy before, only masturbated to her Instagram pictures, and whatever her sister would send me. She was wearing a striped pale blue clop top, and a short high waisted tight white skirt. From the way her big breasts sat in her top, I could tell she wasn’t wearing a bra. Having her stand in front of me like this, as unexpected as it was, was proving to be quite exhilarating, resulting in my cock twitching again in my grip. This seemed to be a reality check for her, as if to bring her back from her daze to what was happening, as she yelled, “What the fuck are you doing dude?? Gross! And what are you watching? Oh my god!”
“Fuck, I’m sorry! I didn’t think anyone was coming home,” I replied sheepishly, but still holding onto my cock, and making no attempts to put it away.
“Why do you have a picture of me up? I don’t even know you! And is that.. oh my god, is that my sister? What the fuck, you’re disgusting!”
“Look I’m sorry ok, I didn’t expect to be walked in on!”
Izzy looked at me skeptically. “Really? Then why was the door open? You did this on purpose didn’t you? Fucking perve!”
“Yeah, but, I thought it’d be your sister coming home, and it wouldn’t have been that weird for her ok, just stop judging!” I replied, a little annoyed now.
“Not that weird? You’ve got a picture of me there too you weirdo! How fucking old are you anyway? Gross!”
My annoyance grew. “I’m 30,” I replied, now actively stroking my cock again whilst looking straight at her. “If it’s weird, you could just leave.”
Izzy paused and fumbled her words for a moment.

“I’m not gonna stop, I’m way too hard, so if you’re grossed out, just leave,” I pushed, looking to gauge her reaction. Her brattiness had sparked my renewed vigour as I slowly stroked up and down my length. I watched her face as I stroked, her eyes fixated on my hand moving over my cock. “You can’t seem to take your eyes off it anyway.”
“I.. I.. No, you should stop!” Izzy mumbled, still staring.
“You like watching this old man stroke his cock in front of you don’t you?” I growled, now more aroused, at her staying.
“No! Gross! Stop..” Her words trailed off as she had to lick her lips to clear the involuntary mouth watering response she was having whilst watching. I had been edging myself too long and had worked myself up into a bit of a mood, and her responses were driving my over the edge of being able to restrain my primal urges.

I stood up, lifting on leg up onto the bed, and slowly stroked the length of my shaft, as Izzy stared, mouth open, as if transfixed.
“Come here,” I instructed, directing her towards my cock. She froze and nodded no hesitantly, Her brattiness had subsided, almost as if mesmerised by what she was watching. “Come here so I can fuck your throat,” I growled.
She walked slowly towards me, and as she neared my reach, I grabbed her arm and threw her over the edge of the bed, bent over it, and her letting out a little yelp of surprise in the process.
“You never post pictures of your ass on insta, so you’re gonna let me stroke to your ass now. Take off that skirt,” I instructed.
“Ew! No! You gross old perve! AH-” Her being bratty again was met with a firm slant to her ass over her tight skirt. I continued to stroke as I spanked her again. “AH! Ok ok! Stop! I’ll take it off!”
I stepped back and watched as she slowly unzipped and pulled down her tight little skirt, revealing her pink lacey panties, scrunched up between her round cheeks.
“So that’s what you’ve been hiding from me huh?” I asked as I stroked more vigorously over her exposed ass, spanking her as I did. “You like having and old man stroke his cock over your young slutty little ass?”
“Noo, I want you to stop..,” she moaned softly into the mattress, as I hovered over her ass, groping and spanking it whilst furiously masturbating over her.

“Turn around,” I instructed. Izzy slowly obeyed, looking a little nervous as she did. I moved closer to have my throbbing veiny erection right over her face. “Open your mouth”
She looked away hesitantly. I was now acting purely on primal instinct, and couldn’t hold back any longer, so I grabbed her by her hair, and made her look up at the veiny monstrosity terrorising her. As she looked up at that thick veiny cock nervously, I slapped her face with it, on one cheek, then the next, making sure to get some precum on her face.
“Eww! My god! Gross! It’s so hard and warm! And gooey!” She moaned.
“Yeah, you like that don’t you? You’re gonna be a good little slut for me just like your sister aren’t you?”, and before she could answer, I shoved my cock into her mouth, muffling her answers with my throbbing cock, moaning out loud as I did. I began to thrust into her mouth slowly, deeper with each push, easing her into taking more of me in her. Her reluctant moans eased into submissive unexpected sounds of pleasure as she eased her throat into being filled by me.

“Good girl,” I encouraged, “I knew you’d like choking on this old man’s cock.”
I thrust deeper still, and hearing her choking and gagging on my length encouraged me to thrust faster and harder. I took a moment to relish what was happening, beyond my wildest fantasies. There I stood, completely naked, with the door still open, in my friends spare room, her younger sister kneeling beside the bed in front of me, my hand holding her by her curly blonde hair, guiding her as she stroked my cock with her throat. I moaned and grunted as I continued to thrust, encouraging her by telling her what good little slut she was being for my cock. I was so lost in the pleasures of fucking Izzy’s throat, that I didn’t hear the door opening once again.

“What the fuck are you doing?!?”
I suddenly opened my eyes, my cock still down Izzy’s throat, but pausing from thrusting. The sudden yell had taken me by surprise. Standing there naked, with my bare ass to the door, I could feel a glaring presence. Slowly turning my neck, I glanced back over my shoulder, to see my friend had returned from her lectures, and stood at the bedroom door, witnessing her younger sister’s throat being fucked by her house guest. To my surprise, I could feel Izzy’s tongue swirling around in her mouth, teasing the head of cock whilst I was looking back at her sister. This turned me on beyond where I was already at, so without breaking eye contact, I turned myself, and Izzy, to the side, to give her sister a better view, and proceeded to thrust into Izzy’s throat while her sister watched in shock. I looked at my friend and smiled, “you know what to do!”

She had watched mer jerk of to pictures of her sisters many a time, and had lead to her outburst the previous night. And now here I was, fucking her 18 year old sister’s throat, in her house, while she was forced to watch, yet again. I grabbed Izzy’s hair and started to fuck her throat as forcefully as I could, with the renewed vigour of being watched by her sister. The room was filled with noises of Izzy’s moans, mixed with the wet noises of my cock thrusting into the back of her throat, while she gagged and secreted even more saliva, and my pleasure marked by my grunts and moans as I thrust. All of this had me in a frenzy of primal lustful decadence, and I wanted to indulge that impulse even more.
“Come here, and get on your knees to,” I instructed my friend. “But kneel behind my ass. You’re going to eat my asshole as I fuck your little sister’s slutty little mouth.”

Standing frozen at the door, she couldn’t believe what she had heard me say to her. She was still in shock of what she had walked in on, but could also see the fire in my eyes as I glared at her to do as she was told. Slowly, she hesitantly moved towards me, as I thrust into her little sister, and then kneeled, and crawled up behind my ass. I slowed my thrusting to allow her to get into position, growling at her in my impatience. As soon as I felt her tongue tease my hole, I let out an orgasmic guttural moan of please. Feeling my cock being milked by Izzy’s throat, whilst having her older sister lick my asshole had me in pure ecstasy. Moaning still, I started to slowly thrust into Izzy again. It seemed as if my expression of extreme pleasure was encouraging to Izzy, as she began to show some initiative by swirling her tongue over my frenulum, as her sister tickled my asshole with hers, together holding me on the edge of an intense orgasm. I couldn’t help but push Izzy down onto my cock and thrust into her as deep as she could take me, and hold her there, as I felt her sister enthusiastically clean my asshole with her tongue, until Izzy had to tap on my thigh to gasp for breath, and I needed a break so as not the drown her in my cum.

Both Izzy and I were panting heavily, her from being choked by my cock, and me from the intense sensation of being pleasured by the two sisters, exactly how I instructed. While Izzy tried to catch her breath, I proceeded to slap her face with my cock, now drenched in her saliva and my precum, making sure to leave a slobbery mess on her face. I had now developed a more ravenous appetite, and without much warning, I lifted Izzy, and threw her onto the bed, and turned her to have her ass facing me. In my building impatience, I ripped off her little pink panties, to expose her young, now deliciously soaking wet 18 year old pussy, my cock twitching with anticipation at the sight. I instructed her sister to get around to the other side of the bed for a better view, to watch me fuck her little sister. Positioning myself behind Izzy, I pushed my wet cock at her entrance, teasing her, and watching her twitch at the sensation, before slowly pushing myself into her, filling up her little hole. She was tight, very tight, and she moaned, half in pleasure, half in pain, as she felt me stretch out her little hole, reaching out a hand to hold her sister, as she took me inside her. I began to thrust, looking down at the tight little 18 year old slut I was fucking, holding the hand of her older sister for support as moaned with every deep thrust of my cock. I watched her round ass jiggle as my hips slapped against her with each thrust, begging to be groped and spanked, causing her to yelp, as I indulged myself.

“Do you like watching me fuck your little sister like this?” I asked my friend, provokingly.
“No,” she replied quietly, avoiding eye contact with me.
“Look at me,” I growled. She obeyed. “Tell me you like watching me fuck your little sister!”
“I like watching you fuck my little sister,” she mumbled quietly.
“I can’t hear you!”, I growled, as I spanked Izzy for my friends impudence.
“I like watching you fuck my little sister! I really do,” she yelled, as she heard her little sister yelp again as I spanked her ass yet again. There was a change in the tone of Izzy’s moans now, a rush almost. Her moans hastened, shorted, and were building rapidly with my thrusts.
“What’s going on with you?”
“I.. I think.. I’m gonna.. ahhh.. ahhh..,” Izzy moaned.
“What? Speak!”
“I think I’m gonna cum!”
I grabbed Izzy’s hips and pumped into her harder, and deeper, causing her to moan even louder.
“Don’t you dare cum unless I tell you to!”
“I.. I can’t help.. it..”
I continued to pump my cock into her faster. “Don’t you fucking dare!”
“Ahhh.. ughhhh! UGHH!” Her moans turned into grunts, her body spasming, her clenching grip on her sister tightening, her little pussy squeezing, strangling. I thrust my cock as deep into her and stood there, enjoying the spasms of her little pussy on my cock as she moaned through her seemingly intense orgasm, with gush of wetness forming, squeezing out her little hole, and onto my pelvis and thighs. I began to slowly thrust again as her orgasm eased and she continued to spasm intermittently wiht after shocks.
“You fucking little slut!”, I growled, as I spanked Izzy’s ass. “I told you not to cum!”
“AH- Sorry! I’m sorry,” she moaned and yelped as my spanks on her red ass caught her by surprise.
“I”m gonna have to punish you for this!”

Without warning, I pulled out of her little pussy, and pushed my soaking wet cock over her tight little asshole. This caught Izzy and her sister by shock and surprise, and she clenched, trying to stop me from entering, but I pushed, and with how wet her pussy had got from her orgasm, and me thrusting harder, slid into her tight little hole. Izzy’s leg began to shake as she felt me stretch out her asshole, and she blurted out, “fuck, fuck, fuck, fuck, FUCK!”
“Mmm you like that don’t you, you filthy little whore?”
“Yes, yes, yes, fuck, fuck, FUCK!”, she moaned.
“You cock hungry little slut, I’m gonna fuck you asshole”
“Yes, yes please, fuck! You’re gonna make me cum again!”
I thrust slowly deeper into her tight little hole, making her moan even louder as I filled her even more. Her legs began to shake more violently, and her moans again turned into grunts. Once again, I could feel a gush of wetness from her little pussy, now against my balls hanging at her entrance, as she came from her asshole being filled by my cock.

After her second orgasm eased, I slowly pulled out of Izzy’s ass, watching her lay there in her post orgasmic haze. I looked at her sister and instructed, “come taste your little sister’s asshole off my cock.”
Both her, and Izzy suddenly turned to look at me to see if I was serious. I smirked and growled and directed my friend to get down on her knees and clean my cock. She was slow with hesitance, but as soon as she was kneeling in front of me, I grabbed her dark hair, and pulled her head back, and slapped her face and rubbed my messy cock over her face, before directing it into her mouth. I didn’t allow her to feel me fuck her mouth, as she didn’t deserve it, but I instructed her to lick my cock clean.
“Taste your little sister’s asshole off my cock, and clean my cock!”
She obeyed, and her enthusiasm for finally getting to feel my cock was evident. I pulled her hair again to stop her from taking me too deep.
“Ah Ah! You don’t get to feel me down your throat. You’re just here to clean my cock with your slut tongue. And while you’re there, lick your little sister’s pussy juice off my balls too!”
I watched as she obeyed obligingly, and proceeded to stroke my cock over her face as she tasted her little sisters cum off my balls. I was getting close, and I was ready to make more of a mess now.

“Get down on your knees too Izzy, you’ve rested long enough. You’re gonna make me cum now,” I snarled. I then directed her sister back to my asshole whilst Izzy kneeled in front of me. I stroked my cock over her face and intermittently used her mouth to stroke me.
“Can I get your cum too please?” My friend paused from licking my asshole to beg me, but my snarling response directed her back to teasing my hole.
Looking down at the messy young face of the young sister I had jerked off to many a time, was getting me ready to explode. I wanted to make a mess on her, leave her drenched and soaked in my cum, and having been stroking and edging, initially by myself, and then with the sisters, I knew I was about to unleash a big load.
“I’m gonna cum!” I announced, “keep licking my asshole, and Izzy, open that slut mouth of yours and show me your tongue! Beg me for my cum you little slut!”
I grunted and growled and moaned as I stroked myself closer and closer. I was ready.

I unleashed onto Izzy’s young, hungry, messy little face, spurt after spurt, grunting and moaning in ecstasy with each. I watched as it sprayed all over her little face, into her curly blonde hair, into her left eye, on her tongue and into the back of her throat, causing her to gag, then down from her cheeks, to her shoulders, and her blue crop top she still had on. Izzy’s face was a beautiful mess, a painting with my cum as the paint, and her face as my canvas. I had covered many of her photos with my loads before, whilst her sister watched, but I had finally been able to unload onto the real thing, and I made sure there was no shortage of thick white sticky cum to cover her.

I collapsed onto the bed from the release, but I had one more thing I wanted to see.
“Lick my cum off your sister’s face and tongue, and share it with each other, like good little cumsluts.”
