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

"Get here ASAP! Need you!!"

I read the text from my older sister Sandy. I was intrigued by the commanding tone. This wasn't her asking she was telling me to go and see her! After our two previous incestuous encounters and especially the last time it was pretty clear that Sandy had a bit of a kinky side to her that she wanted to explore. I decided to tease her a little.

"What for? Laptop fucked again?" I replied. A moment or two passed.

"Just do as you are told little brother" she replied.

"What if I don't?" I teased further.

"Yeah like you won't! Pls cum soon ;)" she texted back. I smiled. I wanted to fuck Sandy again as much as she wanted me. So I made my excuses to my wife Liz once more and made my way to Sandy's flat the next evening.

When I arrived outside her flat she was standing waiting for me at her door as before. This time she was wearing a black, loose fitting, silk dressing gown that stopped short just above her knees. Her feet were bare and the gown was low around her bosom revealing her beautiful, freckled mature cleavage which seemed much larger and prominent than it had before. Her hair was immaculate as ever and she smiled at me from under that long wave of blonde hair that hung over the left side of her face as always. She looked stunning.

"Hi!" I said smiling back at her.

She didn't answer but just stood aside to let me in and then closed the door and locked it. She turned and looked at me a second and then stood in front of me so close that her breasts were touching my body ever so slightly. She looked up into my eyes and I looked into hers as she pulled her hair from her face. We held each other's gaze for a few seconds before she quietly said;

"Hi."

I couldn't resist her closeness and quickly kissed her full on the lips. She responded just as keenly and slipped her tongue between my lips which I sucked in gently. I reached around to embrace her but she caught my arms and pulled away gently breaking the kiss.

"Tim take a shower and then come to my bedroom." She said looking away from me and then walked past me into her room. I stood there a moment aching to follow her as my cock was already swollen. But I did what she asked and entered her bathroom to take a quick shower. I turned on the water and stripped off my clothes. My now semi erect penis was oozing precum from the delicious excitement of what was to come. I duly showered myself down quickly taking extra time to clean my genital area and between my buttocks to ensure I was clean and fresh everywhere that mattered. When done I turned off the shower and dried myself down quickly. I took another dry, white towel that was hanging on the rail and wrapped it around my waist and then left the bathroom for Sandy's bedroom. Sandy was sitting on her bed waiting still in her silk gown. She smiled at as I came in and then stood up and came towards me.

"Tim...um....look I want to do something. Or rather behave in a certain way with you but I'm not sure you would like it."

"I said I'd do whatever you want sis. I'm up for anything kinky you know that so don't feel weird or anything. Just let yourself go. Be what you want to be and do what you want to do. I'm here for you for anything you want OK?" I said smiling and put a hand on Sandy's shoulder.

Sandy smiled back and stepped closer and put her hands on my bare chest. "Just understand that I've never really done this sort of thing.."

"Hey me neither!" I said clasping her upper arms. "Well...you know..not um....me and Liz have done some weird stuff you know but......crud I don't even know what you've got in mind Sandy. But it's fine. Really. Just be what you want to be!"

Sandy looked into my eyes and smiled with a twinkle in her eyes. She took two steps back from me and slowly pulled her gown down over her shoulders and let it drop. I gawped as I took in the sight of her. She was wearing a black leather lace up underbust corset that lifted her tits up making the bulging cleavage I'd noticed when I arrived and a pair of black lace panties that were very transparent. Her bush clearly showed beneath it. She stood there a minute with her hands on her ample hips accentuated by her tightly laced corset. I stared at her a minute then took a step towards her.

"Stay still!" she said sternly. "Don't fucking move!"

I stood there as motionless as I could. My heart was beginning to really thump and parts of me were beginning to quiver with expectations.

"First we get rid of this!" Sandy said as she reached out and yanked the towel from around my waist revealing my now erect cock. She stood closer to me and her right hand reached out and touched my chest. I started to raise my hands to her but she grabbed them tightly and pushed them away making my stumble a little to one side.

"I said don't fucking move!!" she said even more sternly than before. I dropped my hands but started to turn to towards her but she grabbed my shoulders and turned me around so I was facing away from her.

"Stay!!" she commanded and then giggled quietly.

I felt her hand softly caress my left buttock and then a finger trace up and down the line of my crack. She ran her finger up and down between my buttocks several times before running her fingers gently all the way up my spine and then around my neck and up to my ear which she suddenly grabbed and pulled firmly. I almost cried out but her left hand reached up and covered my mouth and I felt her soft hair against the left side of my face.

"Now are you going to be a good little brother and do what you are told for your big sister? She half whispered in my ear.

I nodded. I was partly highly aroused, partly amused and partly wondering just how far Sandy was going with this.

"Well you better you little shit!" she spat and shoved me forward onto the bed. I turned as I tumbled onto the bed and looked up at her. She was standing there with a hand over her mouth trying not to giggle.

"Sorry Tim. This is hard to take seriously!"

"It's OK!" I said. "Please I like it. Honest!"

"You sure?" she said stepping up close to the bed.

"Yeah, yeah definitely. Really...just go for it. Call me names.. anything it'll be fun!" I said leaning back onto the bed. My cock was standing to attention proudly.

Sandy re-asserted herself and put her hands back on her hips. She cleared her throat and managed to look serious as she said "OK you little prick get over on all fours and show me your arse!"

I did as I was told and got up onto all fours. I felt the bed give as Sandy knelt on it behind me and then felt her hands run slowly up the back of my thighs before gently caressing my buttocks.

"Now then!" Sandy said huskily. "Don't move!"

"OK!" I replied almost breathless with expectations.

"What? That won't do!" she said and smacked me quite hard across my bum cheeks. "You must say 'Yes Mistress!'...got that?"

"Yes Mistress!..Yes Mistress" I replied obediently.

"Good boy!" she retorted. "Now then you will be still."

"Yes Mistress!"

I felt her hands on my arse cheeks again but this time she gripped both buttocks firmly and I felt her spread them. I few seconds passed then I felt a cool air blowing on my anus. Sandy was blowing on my hole. I tried to look between my legs but my cock and balls blocked the view. I couldn't help a gasp as I suddenly felt the warm, wetness of her tongue gliding upwards over my anus and then down again. She then started circling her tongue around my ring which made me lift my head and gasp louder.

"Fucking hell Sandy!" I couldn't help but say.

"SMACK!" A shot of pain shot from my right thigh as she smacked her hand across it hard. "What did I fucking tell you? You fucking bastard what did I TELL YOU?" she almost shouted.

"Yes Mistress..Yes Mistress..I'm sorry Mistress!" I blurted out and buried my grinning face against into the bed.

"Don't move or else!" she said and I felt her move off the bed. I heard her fumbling with something from her bedside and then felt the bed give again as she returned.

"Don't move!" she said once again.

"Yes Mistress.." I mumbled from the bed. I then felt something very wet and cold being smeared on my hole with her fingers. I sucked in breath as she then pushed a wet, slippery finger fully up me in one single action. She wiggled it and gently pumped me a few times before removing her finger.

"OK. Now you stay still!" she said firmly and I then heard a soft buzzing noise before something hard and vibrating suddenly pushed against my anus.

"Yes that's right little brother I'm going to shove my vibrator up your arse. And I'm going to fuck you good and proper with it."

"Yes Mis...tress....uuhh." I replied as she pushed the vibrator firmly against my hole. I was no stranger to this sort of thing as my wife Liz often used a prostate massager on me. So I knew to relax and just let it happen. Sandy giggled slightly as the vibrator slowly started to make it's way into me. She wiggled it a little and pulled it out slightly before pushing it in again and this time my sphincter relaxed I felt the cool, smooth vibe slide into me. The feeling of the vibrations buzzing my hole was exquisite but the fact that this was my big sister doing this to me made it something very special. Sandy worked the vibe in and out of me gently for a bit. I moaned quietly with each inward thrust my sister gave me.

"OK little brother lie on your back!" Sandy commanded and pulled the vibe out of me. I did as I was asked and was relieved to be off my knees and able to see my sister. She knelt there smiling at me with her purple vibrator still buzzing away. She held it up in front of her face. "Just think. This has been up my cunt many times and even up my arse. Now it's been up yours!" she grinned. I grinned back and then watched fascinated as she stroked the vibrator against her cheek. There were still traces of lube on it but it otherwise looked clean despite where it had just been. But then to my amazement Sandy opened her mouth and then licked nearly the whole length of the vibrator. "Mmmm..." she moaned and then while still looking at me with a smile she opened her mouth again this time engulfed it around the vibrator. She pursed her lips around it then gently pumped it in and out of her mouth before pulling it out then licking it's length once more.

"Tell your Mistress what she is!" Sandy said as she took my cock in her hand now and started masturbating me.

"Umm....uh...She's wonderful!" I responded but that received a smack on my thigh and a sharp squeezing grip on my cock.

"No you prick! What am I? I just licked this thing that's been up your arse for fuck's sake so what does that make me?"

"A dirty slut!" I replied taking a bit of a gamble.

"Better." She said and started slowly masturbating me again. "Is that all? Tell me what I am you little pervert. Tell me what I am!"

Before I answered she put the vibrator to my anus again and pushed it into me. It slid in much more easily this time and I moaned as it did so. She started fucking my hole with the vibrator quite vigorously. "Tell me!"

I gulped before saying almost groaning..."You're..a ..dirty..fucking..bitch..dirty ..slut...dirty ..fucking ..slag"

"Yes that's right! What else am I?" she responded fucking my hole even faster and harder now.

"Fucking ..cock sucking.. .ass licking...cum whore!" I cried as she fucked my hole furiously now while yanking hard on my cock at the same time.

"You'd better believe it brother!" she gasped in response then suddenly stopped what she was doing and got off the bed. I lay their breathing heavily. The vibrator still stuck up me and buzzing away delightfully. I watched Sandy as she took off her corset revealing her large sagging breasts. She slipped off her panties and then climbed back on the bed.

"Fuck Tim I'm fucking soaking. Fuck me now as hard as you fucking can!" she begged and lay flat on the bed beside me. I sat up and the vibrator slipped from my hole. She grabbed it and spread her legs wide. "Fuck me you dirty bastard!" she commanded loudly.

I lay on top of her and guided my hard, dripping cock to her open, glistening gash. It slid in effortlessly with a single thrust with such a beautiful feeling for both of us that we both gasped at the same time. I was desperate to cum now and started fucking her hard.

"Yes..yes...fuck....harder...faster...faster..fuck..me..Tim..fuck..me!" she gasped in time with my quickening thrusts.

I fucked her as hard and fast while trying to last as long as I could. Sandy was moaning and panting along with me and then suddenly she lifted the vibrator in her left hand up to her mouth and sucked it in. She held it in her mouth and opened her eyes wide at me. I knew what she wanted and shifting my weight onto my left arm and took hold of the end of the vibrator buzzing in her mouth and started thrusting it in and out of her while still managing to fuck her at the same time.

"This what you want big sister?" I said sensing it was my turn to get dominant with her. "You want your mouth fucked by a vibrator that's just been up your brother's arse and cunt fucked with his cock?" I said feeling carefree now as I became closer to orgasm.

Sandy moaned and opened her mouth wide. Lapping her tongue around the vibrator. I pulled it out from her mouth and smeared it all over her face before sliding it back into her mouth which welcomed it with pursing lips. I let go of it and focused on fucking her now which I did as hard and fast as I physically could. Sandy grabbed my back and dug her fingers hard into me. I felt my orgasm coming and arched my back against her grip which only hurt more but that only seemed to intensify the incredible orgasm that swept up through me.

"Aaaaahhhhhhhhhhh" I cried out as my cock exploded with cum deep inside her. I rammed myself as hard as I possible could into her with each ejaculation it felt as if I was almost hosing her inside. I collapsed on top of her sweating, panting and exhausted as my orgasm subsided. Sandy spat out the vibrator that was still buzzing in her mouth and gently pushed me to one side making my still hard cock slide out of her. I rolled onto my back but Sandy sat up and then gently leant over me to hold my cock and then take it into her mouth. She lovingly caressed it with her lips and tongue. Gently sucking it clean of my cum and her juices while her beautiful blonde hair caressed my right thigh. She sat up again and then lay back beside me and started fingering herself furiously.

"Christ I need to cum so bad!" she moaned. "Get the vibe Tim and stick it up my bum!" I was exhausted but did as I was told. I lifted the vibe off the bed where it lay still buzzing away and knelt up beside Sandy who was now giving her soaking cunt and real workout with her middle and index fingers of her right hand. She was breathing heavily through her teeth as I poked the vibe into the dark cleft under her furiously working hand. But I was unsure exactly where her anus was so Sandy quickly took the vibe from me and quickly worked it into her own hole.

"There now fuck me hard with it you bastard" she grunted as she went back to work on her clit. I did as I was told and pumped her rectum as hard and as fast as I dared considering the vibe had little lubrication now but Sandy didn't seem to care. She was clearly in absolute ecstasy as I pumped the vibe in and out of her anus as she rubbed her clit with incredible speed. Eventually she went rigid and arched her back. Her eyes rolled and her mouth opened wide before finally letting out a scream that quickly became a long groan and ended with a long satisfied sigh.

I lay beside her on the bed and put my arm across her gently fondling her left breast. I nuzzled into her and locked my right leg between hers feeling her warm, wetness against the inside of my thigh. We lay motionless like this for a few moments before eventually Sandy sat up and then leant over me. Her breasts squashing against my chest and that beautiful wave of blonde hair hanging down and softly caressing my cheek.

"Well Tim we did it again!" she said smiling.

"Yeah. We did." I replied and she kissed me full on the lips. Our mouths opened and we explored each others mouths a little before breaking off.

"I fucking love you little brother!" she giggled.

"And I fucking love you big sis!" I replied and kissed the end of her nose.

"Should we do this regularly?" she asked stroking my cheek.

"As regularly as possible!" I replied stroking her hair.

"Want to get more kinky?" she whispered in my ear.

" I'll do whatever you want Mistress." I said sliding my hand down her back. "Whatever you want."

We kissed and started fondling and caressing each other. Eventually I became aroused again and we fucked once more this time Sandy on top. Her huge breasts and her beautiful hair bouncing as she gasped and grunted eventually bringing me to my second orgasm. We collapsed into each others arms once more and lay still again for a few moments before we eventually got up, showered and dressed. I was going to be late home but I didn't care.

Two months later my world was turned upside down when my wife Liz left me. It turned out she'd been fucking one of her friend's husbands and they had decided to get together. I was stunned. But had no cause to be angry given that I'd been screwing my own sister at the same time! So Liz and I broke up. She wanted to live with her new guy and I wished them luck. I even let him buy out my half of our house so they could live together there.

"Where will you stay?" Liz had asked me.

"Don't worry about me. Sandy will put me up!" I replied trying very hard not to smile.
