Twinsest!

Holly

I know Molly is thinking back and I wonder just what episode from our long and creative past she is replaying in her mind as she waits to torment me again. The first time that she spanked me? When I had angered her by refusing to take the blame for something she had done? It had been useless telling her that the teacher had already informed our mother that it had been Molly and not me who had been flaunting her half naked body in front of one of the older boys in the little grove of trees in the school playground.

"I was in cookery club, Molly!" I had hissed as she had kept on nagging me to confess to the crime. "Mum knows that as does the teacher!"

"Just say we swapped, Holly. It won't be the first time we have done that!"

For once obdurate, I had stuck to my guns and how I had been made to suffer after Mum had given Molly a lecture then put her over her knee and spanked her soundly. I think it was the sheer embarrassment of the latter that made her get her own back on me the next day when we were out in the woods near our home. I had been ordered over a rotting tree stump and then Molly had sat on my back and pulled my skirt up before pulling my knickers up hard so they wedged in the crack of my arse. Then she had begun spanking me, bringing her hand down hard and fast and sending stinging shards of pain into my arse cheeks.

"I hope you don't soil those knickers with your excitement," my twin had stated with a smile on her pretty face as she had smacked my bare bottom furiously. "Mum might find out and give you another spanking for being a dirty girl if you do!"

I could not prevent my body responding though as it was programmed to do. Even when Mum smacked me, I grew aroused, my quim moistening in response to the welcome waves of pain but now I was being punished by myself as it were. My twin, a carbon copy of me, whipping her hand down and sending echoes of pain flowing round the woods. She concentrated on my left cheek while her spare hand pulled at my knickers, making them saw painfully against my labia, splitting the lips in two so that my clit was excited too and I came instantly, squirting mess into the material. Her mocking laughter only inflamed my arousal as her hand spanked the back of my thighs, reddening the tender flesh there swiftly before she removed my knickers altogether and thrust them into my mouth, gagging me effectively. A gag that was needed as her hard hand started to rain down blows upon my exposed pussy instead. I was in agony yet in ecstasy and I came almost continually, juices gleaming on my spread and bruised labia as they grew puffy and purple.

Afterwards, she made me walk home with my knickers still in my mouth while snail trails of my sweet essence leaked down my thighs and glistened in the sunlight. In our room, I had obediently lain down on the floor despite the harsh twinges in my still burning buttocks and then licked fervently at her wetness as she had straddled me. As Molly had grown increasingly aroused, she had ground her soft flesh into my chin and lips, using me for her pleasure until squirt after squirt of wetness had soaked my face. Then, to add to my humiliation and usefulness as her slave, she had made me lick her crinkled furrow for the first time and I had sobbed with delight and degradation whilst eagerly tasting her darkness.

The glass top of the coffee table is cold on my flesh as I lean on it, bottom now bared and my nerves jangling. I can feel the subtle, sensual throbbing of my little clitoris and the tight restriction of the chastity belt that my twin makes me wear whenever I am out of her sight while I wait, throat dry as I wonder how harsh Molly intends to be with me tonight. Will I be going into work in the morning almost unable to walk and certainly not able to sit down comfortably? I long for that and wonder if she knows that and will therefore just be gentle instead. Sometimes it is as if she can read my mind and vice versa so close is our bond as identical twins. The sudden harsh crack of the tawse ripping through the air and down onto my naked arse answers my question and I stifle a squeal as I realise that it is going to be a long and painful evening.

Molly

The supple leather of the tawse is wrapping round the curves of my sister's beautiful arse with a pleasing sound that echoes round the room. As do Holly's little squeals and moans as I warm up her bottom, making it turn pink then red within a few strokes. I carry on, enjoying the sensation that reverberates back up through the strip of leather every time that it touches her soft flesh. A polished glow appears at last and I stop and place my hand on her arse, soaking the heat up into my palm while I marvel at her resilience and bravery. Would I be able to lie there and be struck like that? I shake my head and smile, knowing that I would be fighting back, trying to escape from my tormentor just as I always did when Mum or Dad chastised me. It is peculiar how the pair of us are identical physically and yet our minds are complete opposites. Holly soaks up the pain and it soaks her. Even now, I can see the moisture glistening beautifully on her slit in the light. I need to be in control to get aroused, relishing in having others do exactly what I want when I want them to...which is why I am finding it so difficult to put up with my stupid boss!

Still, I can take out my frustration on my sister, can't I? I snap at her to turn over and remove her clothing completely and she obeys with alacrity, lying back down on the table afterwards while I dangle the tip of the tawse against her pert breasts and the erect nipples. She groans at the first stroke as the tawse almost lazily swirls through the air until the length whips across her chest, crushing her soft tits down. A broad band of red remains afterwards and I add to it slowly but remorselessly until it looks like she is wearing a bright red bikini top.

A dozen strokes across the front of her thighs and then I lay the leather down on the floor and straddle her, hoicking my skirt up above my waist. My wetness slithers down on top of her mouth and she begins to lick automatically so well have I trained her but I don't want her to get too much pleasure tonight.

"You don't deserve that honour, sister!" I snap and I can almost feel the sulkiness slide through her body. "Open that mouth up though because I need a toilet slave!"

As my golden essence flows out into her waiting mouth, I remember making her lie beneath me in the shower, soaking her with my offering time and time again over several days of training. Firstly, I had covered her feet and legs then moved up slowly to shower her pussy and hips on the second day before her breasts had been the recipient. Her face was on the fourth day and then I had used a funnel on the fifth, channelling all my pee down into her, making her swallow it down and then thank me afterwards. Even then, she had been a natural and now she was perfect, drinking down all my flow without spilling a drop.

I squeeze out the last few golden droplets and then allowed her to lick me dry before I stand and go off to find my favourite strapless strap on vibrator. An oxymoron I am sure and yet such a good description really of the toy. So much more advanced than the harness dildo I had first fucked my twin sister with several years ago and so much bigger too!

Our toy chest is crammed and I rummage through, smiling broadly as I come across the penis gag that I had used on her one day when I had decided it was time for me to lose my own maidenhead. No man was going to be given the honour of breaking me, I had thought, and so I had fitted Holly out with the gag, restrained her tightly on our bed and then teased my pussy, soaking from her tongue's skilful licking, down onto the broad bulb of the phallus sticking up. The pain had taken me by surprise as I had lowered myself further down and I had nearly given into it and stopped. But then I remembered how Holly had borne it and I steeled myself and sank down hard and fast, uttering a squeal as my hymen broke and blood dripped out, staining the tip of the penis red. Sore and aching, I had made my body move up and down on the impaling shaft, gradually feeling pleasure replace the sharp pangs of pain until I had gasped into my climax, body shuddering from head to toe. It had been delightful to be teased up to another orgasm afterwards by Holly's silken tongue slithering in and out of my quim, tasting my blood mixed with my excitement.

Holly

I lie on the table and wait patiently for Molly to return. I am praying that she is going to remove my belt and then fuck me...somewhere, anywhere! I love feeling her slide a dildo in and out of my slit, her hips pushing my thighs apart. I can still visualise the first time she had had my tight arsehole, making me beg for her to take me there as I had crouched down, head touching the floor so that my arse cheeks, beaten bright red, were raised upwards for her to play with.

She had oiled my virgin ring with my own lubrication, smoothing it into the crinkled furrow with her fingers and sending shivers running up and down my spine. Minutes of that sweet torment before she had knelt behind me, harness dildo bobbing up and down like a real cock until she had centred the head against my tiny pucker and pushed ever so slowly.

I smile at the memory as Molly strides back in. She raises an eyebrow at me then grins back as she shows me the large vibrator in her hand. I clench my teeth around the end that is going to slither up into me soon and watch in awed fascination as she settles her quim lips on the smaller bulb and starts to wiggle it up inside her sweetness. Her pink pussy lips part and the toy disappears inside her easily before she moves away from me, pulling the large end out of my mouth. The key to my chastity belt is round her neck on a gold chain and she slips it into the little lock and frees me at last. I sigh with delight as the constricting device is removed and placed on the floor.

Molly is between my spread thighs a moment later and I shiver with delight as the swollen knob presses into my wetness. She thumbs the button on the underneath and I am filled with delicious vibrations as is she and our bodies tingle together as she slides the toy in and out of me sensuously, fingers teasing over my beaten breasts and squeezing my erect nipples painfully. Harder strokes as she leans further forward over me, her tongue caressing my ears and then sliding down my cheek until our lips meet. We kiss, lips soft and gentle at first before she slithers her tongue inside and takes control of mine. I am in heaven as she teases me up towards my climax and then I am in hell as she stops when I am just short, sensing my imminent pleasure with her years of experience.

I utter a little groan of disappointment as the large head of the vibrating strap on slips out of my soaking slit and then she pushes my legs up and makes me clamp my arms around them tightly and I know she is going to take me in my little dark hole instead. The excitement is almost too much and my clit seems to throb in time with the rapid beating of my heart as she slithers the slick knob of the cock down my delicate perineum and positions it against my pucker.

"Ask for it, slave girl!" she snaps and I do, instantly disgracing myself just as I had during that first time, pleading with Mistress Molly to use me in my arse. Then I had been more fearful, thinking that I was going to be split apart by the dildo but now I know that my arsehole, tiny though it looks, will stretch to accommodate the fat knob that is just applying teasing pressure.

Just an inch slides in, splitting my ring and making me shudder with delight. I am so accustomed to being used there now and I relish the sheer subtlety of the shame that fills me up each time. The buzzing intensifies as Molly turns the vibrations up and I am already on the edge of exploding into rapture. Another fat inch of phallus slithers inside my darkness and then she is sliding under my arms as they hold my legs up, lips back on mine and strap on sinking in to the hilt. She giggles into my welcoming mouth as my body shudders underneath her, revealing that I am tiptoeing ever closer to the brink of nirvana. Just one long smooth stroke in and then out tips me over the edge and I scream out my pleasure into her capturing lips. I can sense my twin losing control now too and she shafts me harder and faster, suddenly uncaring of anything but her own climax, battering the rubbery cock up inside my anus and making me come again and again. Her own flesh flutters like a trapped butterfly on mine and she slumps down and rests her sweat-beaded forehead in my long blonde hair.

Molly

My sister exhausts me yet again. She remains insatiable and I know that she would happily stay there for another hour or two and let me plunge the strap on in and out of her anal tube. Instead, I let it slip out slowly then feed the end to her and make her clean the sticky knob up before I manage to wearily make it up the stairs to lie on the bed while she runs a bath for us both. A relaxing session soaking in the hot water for a while rejuvenates me just enough to push Holly's head down into my still needy pussy and let her tongue assuage my desire. She struggles as she runs out of breath under the water but I hold her down and only let her surface to snatch in a huge gulp of air before I push her back under, lying back and enjoying the frenetic fluttering of her tongue on my slit. Eventually, I raise enough strength in my weary limbs to clamber out of the bath and then have my devoted sister lick me dry all over, beginning at my toes and working her way slowly upwards until she presses soft dabs of her lips on mine. Bedtime, I declare, and she obediently crawls after me then under the duvet to sleep by my feet like the little pet she is.
