The Spaned Step-Sister

I think my soul must have left my body. My brain certainly did. I walked like an automaton to the sink, my hands at my side, my face flushed and blank.

He looked me up and down and said, "Take your pants down."

My hand went to the button on my jeans shorts before I even knew what I was doing. I undid them and let them fall with a soft fwoosh to the floor.

He smirked. "Underwear too."

I hesitated.

He shrugged his shoulders. "It was alright for you to see me naked, apparently."

And he had a point.

So I peeled off my panties and brought them down to join my shorts in a small pile at my ankles. I stepped out of the leg holes like I was cautiously dismounting a gymnastics vault. Without a word, Jason motioned his head towards the sink, and I leaned over it, placed my hands flat on the counter, and looked at my reflection in the mirror. My eyes were drawn back to him as he adjusted his towel, then met my eyes in the reflection and said this:

"I've been watching you for a while, Lindsey. And you know what I think? Your dad's a good guy...but he's too good to you." He scoffs. "And that boyfriend of yours -- he lets you walk all over him. Well." Here his voice drops, and he speaks directly into my ear. "I don't let those sorts of things slide. You want to come in here and snoop around? Hm? You wanna see my cock?" The hard c of the word reverberates in my head, which I think had gone completely empty since I leaned over the counter with my bare ass sticking out. "Is that what you wanted? Well, how about this?"

I hear the crack before I even realize which butt cheek he's hit -- my right one. The pain flushes through me slowly. I feel as though I'm watching from outside of myself as my eyes in the reflection go wide, my eyebrows rise, and a stinging mark blossoms on my bottom.

The second swat lands in the same spot, and this time is choke out a little gasp: "Ngah!"

"Does that hurt?" he says, looking at my eyes in the mirror. He holds my gaze with such incredible intensity I have to look away. When he's silent for a while, I realize he wants me to answer. That wasn't rhetorical? I think. I nod, biting my bottom lip, trying not to look at the pathetic expression on my reflection's face.

He nods too, satisfied. "Good. But we have a long way to go."

Another resounding clap against my backside sends alarm bells ringing in my ears. I gasp as pain spreads through my left ass cheek and down my thigh. I fall forward onto my elbows, my nose just a few inches from the mirror so I can see the flecks of toothpaste. Another brisk swat lands, and my leg jerks up at the knee. My head is absolutely spinning, and my ass is starting to smart between swats. How is his hand so fucking hard?

I feel him press against the small of my back, and I obediently stick my butt out, arching myself forward and glancing over my shoulder.

Big mistake.

"Keep your eyes forward," he grows, grabbing me by my jaw and redirecting my face to the mirror. My eyes are wide with fear and something else, and my cheeks are flushed. Then, with a small smile in his voice, he adds: "This is only the warm-up."

Warm up?

One thing was for sure: the warm part. He started laying into me, his cupped hand striking my naked ass over and over, spending five or six hard swats on each cheek before alternating to the other, spreading around so as not to leave any of my now hot-pink ass unmarked. I began to realize he was timing the spanks with me: each time I started to squeal and shiver, he knew it was time to switch to the other cheek. Pretty soon, though, I wasn't just squealing: I was crying out loud. A part of me felt freed by it: my wailing echoed around the bathroom, and each time I unclenched my eyes I could see my reflection and feel what she was feeling. I could feel tears welling up in my eyes, and by now each time his hand came down I was screaming, and he was switching between my dancing ass cheeks with the agility of a sushi chef. "Omigosh!" I cried. "Omigosh Jason I'm so OW! So sorry, I really fucked up I OWWWW please, it hurts!"

He laughs -- actually throws his head back and laughs. I hazard a glance over my shoulder, feeling the hot sting in my butt and the even hotter sting of embarrassment in my face as he says. "If you think getting spanked with my hand hurts, you're in for a treat. See my folded clothes over there?" He gestures to a pile of his clothes on a footstool beside the sink. "I want you to give me my belt from that."

My blood ran cold. Like a person in a dream, I stood up straight and went to the footstool. I bent my knees to put it up, rather than bending over, and I relished the cool air between my seared thighs. I took his belt from the pile -- a thick, leather black belt, something that only a guy as tall as Jason could pull off -- and placed it in his expected hand.

"Good girl," he says, and a grin flashes across his face. My stomach is doing cartwheels at this point. "Now bend over and stick your ass out. You're going to count out ten of these for me."

I leaned over the sink and met my reflections eyes. She seemed to be telling me: Oh my GOD did you fuck up now...

The first swat lands like a thunderclap, and the lightning follows soon after. I yelp and kick up my feet, falling forward almost into the sink -- the sting is so intense that I almost for to add, panting and whimpering, "One!"

His arm rises and falls, a hard thwack rings out, and I can hear myself cursing violently, see my face contorted in the mirror, feel the awful belt, still, where's it's cut across my bare ass.

"Gaahaha! Two!"

A third stroke falls, and now I can feel tears welling up at the sides of my eyes. "Th-three!"

And another, faster now, the strap clacking together on its arc: "Ffffuck! Four!"

"Am I going to have to wash your mouth out?" Jason says, leaning over my shoulder to whisper in my ear. He cups my blistered ass with one hand and I squeal. His fingers explore between my thighs and come away wet. "Hm," he says, lifting his fingers to his face. I watch him in the mirror, my embarrassment flaring again, and at the same time the unbearable longing builds. He says, in a low voice: "Seems like you might be enjoying this almost as much as me."

That voice -- soft and gravely with lust. My ass aching, my face flushed, and my pussy wet -- I swear, I almost came right there and then.

"Five more," he says. He places a firm, steadying hand on my back. "Are you going to be a good girl for me?"

My eyes meet his in the mirror again, and I can see, now, in that handsome face, a sort of pride. He's proud of me. My heart swells. I nod, silently, and he smiles.

The last five spanks bring me to my limit and over it. Tears stream down my face as I cry out the final count between hiccupping sobs, my ass bright crimson red and hot enough to bake cookies on, my pussy dripping and my knees weak. When, at last, the spanking is over, he tells me to stand up in a gentle voice. My vision is blurry from the tears, and as I blink my eyes clear, he opens his arms to me. I have never accepted a hug so readily. I wiped my face on his chest, felt the warmth of the bare skin of his back. I closed my eyes, and felt happier than I had in months.

And then, we heard the door open downstairs.

It was my dad and mom, back with take-out food that they wanted us to have with them. They called to us from downstairs, and Jason and I looked at each other wide eyed. We sprang into action, dressing rapidly and silently -- Jason gave me a smirk as he pulled his belt through the loops. I managed to clean up okay: I splashed water on my face and gingerly pulled my panties and shorts over my sore bottom. We went downstairs together, and no one was the wiser -- even when I winced with pain sitting down, I managed to only do it when my parents were looking away.

What were more conspicuous were the glances Jason and I kept giving each other from across my table. Jason -- my stepbrother. Keeping me in line. I had to suppress a smile. As I met his eyes over the platters of Thai food, I knew that this incident wouldn't be the last of its kind, and maybe not even the last spanking. He still lived in my house. He still was my stepbrother. Who knows when we'd be...inappropriate together again?

I squeezed my legs together and bit my lip.

Because I couldn't wait.
