Author's note:

This story involves themes of incest (brother/sister) and light dominance / spanking. Please skip if these things don't float your boat.

For those that rate women on the traditional 10-point scale, my younger sister, Rachel, is a solid 8.

I've told her this many times over the years. Never in a leering way or with any ulterior motive, but because she's always had a crippling insecurity about her looks and is extremely body-conscious.

Her low self-esteem and anxiety has been the major reason that most of her previous relationships have failed. She's making a go of it now with Aiden, but she's been left with the scars of various broken hearts, including a failed marriage from nearly two decades ago, that lumbered on stubbornly for 4 years, but had at least given Rachel a child, Mica.

She'd worked hard on building her resilience and her mental health had improved, but her anxieties still reared their head now and again. She's 39 now, some 6 years younger than me, and has been in a happy relationship with Aiden for 3 years. Though both of them refuse to consider marriage - "been there, done that" - they welcomed little Alice into the world a couple of years ago. She's Aiden's only child, but Rachel's second, with Mica having just turned 19 - a fact I still struggle to get my head around.

I've always been close with Rachel and it bothers me that she can't see herself the way I do. That's why I'm happy telling her, truthfully, that I think she's beautiful.

Again, there's no 'angle'. I just tell her that everyone apart from her can see she is very pretty. And in a world where 'tens' don't really exist outside of photoshopped magazine pictures or airbrushed Hollywood movies, the most desirable women are somewhere in the 8 - 9 region. And she's easily up there, with the potential to go higher with the right outfit and make-up.

She just blushes profusely and tells me I have to say that, as her older brother. And no amount of reassurance ever makes any difference so eventually I stopped trying, letting her brush me off whenever I gave her a compliment.

There was a time for a couple of years, when we'd become so busy with our own lives, working and raising kids, that we didn't see each other outside of birthdays and Christmas. That had eventually seen us getting all soppy after drinking too much at a Christmas house party, and we vowed that we wouldn't let 'being busy' get in the way of us spending time together. So began our fortnightly Sunday fun-days, where we could do family stuff. They became monthly affairs and then bi-monthly, but in their place, we started up our weekly Friday night curry nights, where Rachel, Aiden and I would stay up late - at theirs' so little Alice could be in bed at a reasonable hour - and we'd eat curry and talk about grown up stuff.

In short order, these Friday nights had become the highlight of my week. I'd log-off from work, jump in the shower and make my way to Rachel's for about 7pm. I'd play with Alice for about an hour before she went off to bed and this would usually coincide with Mica heading off for whatever Friday night fun she had planned with the girls.

I'd see her whizz past in a blur of make-up, coiffed hair and exposed flesh, as she dashed out the door with a belated, "Hi Uncle Seth; by Uncle Seth".

Then we'd order three-times more food than we needed and put the world to rights over a few bottles of wine.

It wasn't unusual for us to nod-off and wake up in the early hours of the morning, often being roused by a returning Mica, trying to sneak off drunkenly to bed.

Our bodies would be aching from awkward, upright sleeping positions on the settee, and inevitably, Aiden would start cleaning up, no matter what the time was. I think there was a touch of OCD hiding under the surface but as far as I knew, he'd never had any type of diagnosis.

It became clear that Aiden didn't enjoy the late nights and we could sense his frustrations. He was stuck between not wanting to call an early halt to proceedings, but not wanting to leave us to it and risk waking up to a messy house in the morning.

After a few weeks of this awkwardness, I bit the bullet and told him that if he wanted to get off to bed, I'd make sure I tidied things up before calling my taxi. He'd made a half-hearted attempt to tell me it wasn't necessary, but sure enough, that's the routine we settled in to and it soon became the norm for Aiden to head up to bed at about 11 pm-ish, and for Rachel and I to polish off another bottle of wine between us before eventually calling it a night somewhere between midnight and 1am. Obviously, after making a semi-concerted effort to clean up after ourselves.

It was one particular evening that changed everything. Aiden was in an unusually talkative mood and midnight had come and gone before he decided to surrender to the comfort of his bed. No problem there... other than the fact that we'd already gone through all the wine - including the bottle that Rachel and I normally shared between us after Aiden had left us to it. Rachel was far from ready to call it a night and wasn't in the mood for my warnings that she'd probably already had enough.

"Nonsense," she said, slurring slightly. "You're my brother, not my dad... just grab something out of the cupborad will you?"

She gestured to where she kept the hard liquor. I was in no rush to get back, so I duly acquiesced, grabbing a bottle of Jack Daniels that was still around a third full.

We chatted about the usual stuff, moaning about the price of everything, lamenting the latest political scandal and swapping Netflix recommendations. Noticing she was empty, I poured the last of the bottle into Rachel's glass.

"You'd better be quick with that, you know." I told her.

She looked at me quizzically.

"You still need to clean up. There's cold curry all over the place and all these bottles and glasses to wash up before the morning."

She huffed. "Don't worry about it."

For a split-second a look of anger flashed across her face.

"He'll only be on your back about it in the morning if we don't sort it out tonight," I said.

Again, she huffed. There was an uncomfortable pause.

"If only!" she said, after a moment.

"What does that mean?" I asked.

She shook her head and looked away.

"Rachel?" I asked.

She took a swallow of her whiskey. "I wish he would get on my back about it," she said.

She read the confusion on my face and gave an awkward smile, before continuing.

"He won't be happy.. but he won't shout. He'll just sulk." She paused for a moment.

"He's just so... limp!" she said.

"I'm not following you Rach," I told her.

She swirled the whiskey in her glass, deftly grasping the rim between her fingers. Exhaling in a deep sigh, I could tell she was fighting to find the right words. Her tone was a mixture of frustration and annoyance and the 'old No.7', combined with the wine, was loosening her tongue and freeing her inhibitions to allow this out of character confession.

"Sometimes..." she hesitated a little. "I wish he would just take me by the shoulders and TELL me what to do."

My face flushed and I glanced at my glass, wanting the liquor to be the reason for the sudden temperature increase.

"Is that weird?" Rachel asked. "Do you think I'm some kind of freak?"

I couldn't think of the right response, so I shook my head softly.

"I'd like it," she continued. "You know... if he... took charge." She was blushing too now.

"What?" I asked, finding my voice. "You want him to start bossing you around in the kitchen?

"Not just the kitchen!" she shouted. She took a moment to compose herself.

"In the bedroom too!" Her eyes had glazed and it was if she were talking to herself, not me.

"God!" she trilled. "I'd love him to boss me around in there, but he hasn't got it in him."

I didn't know how to respond. I just watched her squirming a little in her seat with a distant look on her face.

We'd never talked about relationships or about sex, so this was completely new ground for us. Plus, I didn't really know how to contribute appropriately. To be honest, I was used to being pretty dominant sexually, and Julie, my wife, loved it when I was a bit rough. Pulling hair, scratching, giving her 'sexy instructions' was all pretty vanilla for us at home. But sharing that with Rachel might be seen as rubbing it in a little.

"Tell him." I said eventually. It was the best response I could manage.

"I have done," she said. "At first, it was just hints. Then I'd wait for him to ask me to do something, nothing in particular... like 'pass me the salt' or whatever. And I'd say... "make me". He just looked at me like I had two heads. Eventually, I just plain told him what I wanted him to do. But that didn't help either. He just said he felt daft. I was utterly embarrassed by the whole thing and we've never discussed it since."

I opened and closed my mouth a couple of times, trying to find the right thing to say. She saw me floundering.

"Don't worry about it," she assured me. "It's my problem not yours."

She eyed my glass after noticing she'd drained her own.

"Are you gonna finish that?", she asked.

"Knock yourself out," I said. "Looks like you need it more than me."

I gave her a reassuring wink.

"Definitely!" she said, standing up and reaching across for the glass. Holding it to her lips tentatively, she sat back down a little too heavily, losing her grip. The liquid splashed down the sweater she was wearing and the glass itself bounced agonisingly on the settee cushion, before rolling slowly off the edge and breaking into several pieces on the hardwood floor.

"Fuck!" she said in a half whisper, listening to see if anyone had been woken by the noise.

She pulled the alcohol-soaked sweater off in an easy movement. Without any noticeable embarrassment or self-cosciousness, she'd revealed her body to me, in nothing more than a skin-tight vest. I couldn't help but stare. Thankfully, her attention was on the broken glass.

I'd not seen my sister wear anything that could be described as form-fitting since she was about 18. Her body-consciousness meant she generally opted for chunky knitwear or hoodies. She had a large collection of loose cardigans and an equally impressive range of overshirts too. Anything that was shapeless, she'd opt for.

I was completely unprepared then, for the vision that greeted me now. It wasn't quite underwear, but it was the thinnest of vest tops, hugging her very impressive chest and being held up by the flimsiest of spaghetti straps. Her dark areolas were clearly visible through the stretched white cotton and my eyes were glued. She was stacked. I'd always had a sense that she had 'ample' boobs, but seeing them like this, well... they were huge. She had the body of a woman ten years younger, and I knew if she ever went out with Mica and dressed for the occasion, they'd look more like sisters than mother and daughter.

As this thought circled my mind, my eyes remained glued to Rachel's body - those tits, her exposed midriff - I could feel myself responding as a familiar ache started up in the crotch of my jeans. Feeling my growing erection came as a shock, and it roused me back to my senses. I shook my head a few times trying to clear the fog and reassert normality. I forced myself to make eye contact with Rachel and to keep my vision firmly above her neckline.

She hadn't noticed anything in particular. I breathed a sigh of relief.

I made a move toward the glass.

"Fuck it." She said.

"What?" I asked, not knowing what she meant.

"Leave it. It can keep till the morning," she replied.

I didn't know if it was embarrassment, frustration or anger speaking.

"You can't leave it," I told her. "What if..."

"I said 'FUCK IT!', are you deaf?" She was glaring at me.

Her face was a deep crimson, her breathing coming in fits and starts. For my part, I was dumbstruck. I'd never seen her like this and she rarely swore. Certainly never at me.

I was angry now too. I had no intention of leaving broken glass on the floor for someone to stumble on to. What if Mica came in and took a drunken fall? What if it was Alice in the morning? I wasn't going to risk that happening.

Rachel was still shouting, almost unintelligibly.

"Shut up, Rachel." I said coolly. She either didn't hear me, or was ignoring me.

"Rachel!" I shouted. "Shut the FUCK UP!"

She stopped and looked at me like I'd slapped her. Before she could respond, I continued.

"Go get the sweeping brush and clean this mess up!" I commanded. She looked defiant, like she wanted to argue about it.

"NOW, Rachel," I said, staring her in the eyes. Her resolve broke first and she looked away.

My eyes fleetingly went to her impressive tits again, and I noticed her nipples poking through.

I thought back to the conversation we'd had about Aiden and being told what to do. Was she aroused? No... more likely it was just the coolness of removing her sweater?

She scuttled off to the kitchen and I could hear things being moved around in the cupboard. She came back to the living room with a dustpan and brush. Dropping to her knees on the rug by the table, she swept up the glass shards onto the dustpan. I watched her chest swinging rhythmically with her movements. She'd pulled her hair into a messy ponytail and honestly, I couldn't recall a time she'd ever looked better. Her nipples had receded by now, leaving just the shadows of her areola.

"Sorry," she said softly, looking me deep in the eye.

I knew she wanted reassurance. A million thoughts fought for dominance in my mind right then. What she'd said... what I'd seen. The wine; the whiskey; that body; those tits...

I knew she wanted reassurance. But at that moment, I didn't want to give her what she wanted, I wanted to give her what she needed.

"Sorry," she said again.

"Save it," I said, firmly. She was shocked, and I noted the prickle of tears on the edges of her eyes.

Seizing the moment, I rose to my feet and stood in front of her. I offered my hands indicating I wanted her to stand up too. She did so, leaning into me for support. Standing a little over a foot shorter than me, I tilted her head by raising her chin with my index finger.

"I don't want to hear another word out of your mouth, until you've finished cleaning up." I said.

She was struggling with how to respond, the closeness of our bodies and the intimate way I'd moved her head to face mine. I didn't want her to overthink what was happening.

Slowly and deliberately, I began gathering her ponytail into my hand behind her head. She could feel it being pulled tight as it coiled around my wrist.

"Do you understand me?" I said, pulling her ponytail, not hard enough to hurt, but firm enough to get the point across.

She moaned instinctively, before mumbling hoarsely: "yes."

I released my grip and sat back down to watch as she wordlessly went about clearing up all the remaining mess. She was smiling and, as I expected, her nipples were once again standing proudly out in front.

A little over ten minutes later, she came back to me and asked if I was satisfied. I made a show of looking around and mumbling, before shaking my head. A look of disappointment flashed across her face, but she caught it and made an effort to smile down at me like a doting child.

Observing her from my seat on the sofa, standing in front of me, exposed and vulnerable, she looked adorable. All sense of right and wrong evaporated from me in an instant as I examined the vision in front of me. She was so eager for my approval. But more than that, she was desperate for submission. That's what she wanted more than anything, to be submissive to me. As much as Julie and I had roleplayed all sorts of these scenarios at home, seeing someone truly wanting to give themself to me... well, it awakened a primal desire.

Rachel had begun squeezing her thighs together, betraying her own arousal, but she hadn't moved, clearly waiting for me to make the next move.

"I'm somewhat satisfied with your work," I told her. "But not with your behaviour."

Without thinking, she immediately apologised again.

"Sorry... I don't know what..."

I cut her off.

"I don't want your apologies. Words are meaningless." I said.

I patted my knees suggestively, as I said: "Clearly, you need to be punished."

I patted my knees again, expecting her to call my bluff. Maybe even to throw me out. Instead, she took a slight sideways step, before pivoting on her heels and lowering herself over my lap.

I knew she could feel my erection poking into her.

I lifted my hand and with a firm swoop, spanked her bottom. Her breath left her in a muffled exhale. I lightly rubbed the spot I'd just spanked, taking a moment to caress my little sister's buttocks. I lifted my hand again, exaggerating the motion to allow Rachel time to prepare. I spanked her again, a little harder. Again, a muffled breath, followed by a very subtle mewl of appreciation. She wiggled a little in my lap, grinding our crotches together momentarily. I spanked her again a few more times before hooking a finger into one of the belt loops in her jeans and giving it a little tug.

I didn't say anything. She didn't move. I tugged the belt loop again, waiting to see if she'd take the hint. I was keen to see if she'd let me escalate. I waited, patiently. This had to be her choice. Her submission.

Maybe she was done now. Perhaps the initial, naughty, sexy flush of excitement had passed and she'd been given what she needed.

Apparently not.

After a moment, I felt her lift her belly and her hands were suddenly busy at the button of her jeans. Seconds later, they were being pulled down and I watched in delight as her ass, red from the spanking, was slowly revealed to me in a pair of delicate white cotton panties.

After another gentle rub, I spanked her again on her now near-naked bottom. This time she moaned. Another spank, another moan; deeper and more guttural. I tugged on her ponytail again as I gave her a third, violent smack. She shifted her weight slightly so that she could actively grind her pussy into my knee and my body tingled at her warmth.

She was now no longer waiting for the spanks. She was riding me hard, dry-humping my legs with fervor and I could feel an intensity building.

"Are you going to be a good girl, Rachel?" I asked in a whisper.

"No!" she said, grinding harder.

"Are you going to do what I tell you?" I asked, pulling her again.

"Yes... I will, I promise!" she said between breaths. "Oh, God yes!"

"Good.." I said. "Because I'm going to hit you again now."

"Oooh." She moaned gently.

"I'm going to spank you one last time..." She squirmed and riggled. "And when I do, you're going to cum".

I waited a beat and then I hit her hard.

She squealed. Her hands shot to cover her mouth. She clamped her legs around mine as a shuddering orgasm wracked her body. I sat, motionless, revelling in the afterglow and savouring the small erotic aftershocks that caused her body to shake and judder gently. As her breathing recovered, I gently ushered her off my lap and she rolled, clumsily, onto the rug.

I knelt beside her and kissed her gently and lovingly on the forehead. We lay together for a few moments before I had a horrible premonition of Mica coming home and finding her mother and uncle in such a compromising position.

I got to my feet and smoothed myself down. Rachel looked up at me dreamily and I was happy that there wasn't a hint of shame or regret in her eyes.

"Good girl," I said, kissing the tip of my finger before planting it on the end of her nose.

I made my way out of the house without another word, confident I'd find a taxi on the main road.
