I Punish My Panty-sniffing Stepbro

By Unknown

I [f22] came home early from the gym and headed straight to the laundry room to grab my stuff out of the dryer. The house was supposed to be empty. My stepbrother Ryan is four years older than me, 26, usually out with his friends or at the gym himself. But when I pushed the door open, he was there standing right in front of the dryer with my favorite black lace panties wrapped around his cock, stroking fast like his life depended on it.

I froze for a second, then pure disgust hit me. “Ryan, what the actual fuck?!”

He jumped, eyes wide, but he didn’t let go of my panties or stop moving his hand. His face went bright red and he started mumbling, “Emmy… shit, I’m sorry, I didn’t think you’d be home…” But his cock stayed rock hard, twitching in his fist like it was enjoying the fact that I caught him.

Something twisted in my stomach. Not just anger — this weird mix of shock and power. I stepped closer, still in my sports bra and tiny gym shorts, and glared at him. “You’re jerking off to my dirty panties? That’s so fucking nasty.”

Before I even thought about it, my leg swung up and I kicked him right in the balls. Not super hard, but firm enough that my bare foot connected solidly with his sack. Ryan gasped, his whole body jerking, but instead of doubling over or yelling at me to stop… his cock throbbed even harder. A thick drop of precum leaked out onto my panties.

I stared, mouth open. “Wait… you’re getting harder? What the hell?”

He was breathing fast, still slowly stroking, voice all shaky and apologetic. “I’m sorry, Emmy… I know it’s wrong… I just… fuck, I couldn’t help it.”

The way he said it, all pathetic and desperate while his dick kept pulsing, made something click in my head. I smirked, feeling this sudden rush. “Do you actually like that? Getting caught and kicked in the balls by your fucking stepsister?”

Ryan bit his lip, nodding before he could even think. “Yeah… a little. God, I’m so sorry.”

I laughed softly, shaking my head. “You’re such a freak.” Then I kicked him again, a little harder this time, my foot smacking his balls with a dull thud. His knees buckled slightly but he stayed standing, stroking faster for a second before he forced his hand to slow down like he was trying to behave.

“Ow… fuck… Emmy, I’m really sorry,” he groaned, but his cock was leaking nonstop now, shiny and swollen, veins standing out. He looked so pathetic and turned on at the same time.

I stepped even closer, tilting my head. “Stop stroking for a second. Hands behind your back.”

He obeyed instantly, letting go of his dick. It bobbed there in the air, angry red and dripping. I watched his face as I pulled my leg back and kicked him again…harder. The sound was sharper this time. Ryan moaned loud, his hips jerking forward like he was chasing the pain. No hands, just pure ball-busting.

“Jesus… you really do like this,” I said, half laughing, half fascinated. “Look at you. No touching yourself and you’re still leaking like crazy.”

“I can’t help it,” he whimpered, eyes glassy. “It hurts so good when you do it… please, Emmy…”

That “please” did something to me. I felt this crazy confidence take over. I started kicking him rhythmically Not full force, but steady, deliberate kicks right to his poor swollen balls. Left foot, right foot, alternating while he stood there with his hands behind his back like a good boy, moaning and apologizing between every hit.

“Sorry… fuck… I’m so sorry, Emmy… I know it’s gross… ahh!”

Every kick made his cock jump and leak more. His balls were turning a nice shade of red, tightening up against his body. I kept going, watching his face twist in pain and pleasure, his voice getting higher and more desperate.

“You’re not even allowed to stroke anymore,” I told him sweetly, landing another solid kick that made him groan deep in his throat. “You’re just gonna cum from your little sister busting your balls, aren’t you? That’s how pathetic you are.”

Ryan nodded frantically and tears were pricking the corners of his eyes. “Yes… yes, Emmy… I’m gonna cum… please don’t stop…”

I didn’t. I kicked a little faster, a little sharper, focusing right on that sensitive spot. His whole body started shaking. His cock twitched wildly, untouched, bouncing with every impact. Then suddenly he cried out a broken, humiliated moan and started shooting thick ropes of cum all over the laundry room floor without ever touching himself again. Spurt after spurt while I kept lightly kicking through his orgasm, milking every drop out with my feet.

When he finally stopped cumming, he was panting and his legs were trembling, balls bright red and sore. I lowered my foot and just looked at the mess he made, then back up at his flushed, embarrassed face.

I smiled, wiping a tiny bit of sweat from my forehead. “Well… that was interesting. Guess I know your dirty little secret now, Ryan.”

He could barely speak, still catching his breath. “Emmy… I’m so fucking sorry… but… thank you.”

I laughed softly and turned to finally grab my clothes from the dryer. “Don’t thank me yet. Next time I catch you sniffing my panties, I’m not stopping until you’re crying and begging. Got it?”

He nodded weakly, a shy, satisfied little smile creeping onto his face.

This house just got a whole lot more interesting.

God, I still can’t believe how fast things escalated after that laundry room thing last week.

It had been exactly seven days since I caught Ryan with my panties and ended up kicking him until he came hands-free like the pathetic little freak he is. We hadn’t really talked about it since just awkward glances at dinner and him blushing every time I walked past in shorts. But I could tell he was thinking about it nonstop. And honestly? So was I.

The way he got harder with every kick, the way he apologized but kept leaking… it did something to me. I wanted to see how far I could push it.

I got home from the gym around 4 pm still dripping with sweat. Leg day had been brutal and my thighs were burning, my sports bra was soaked, and my tiny gym shorts were clinging to me in the grossest and yet kinda sexy way. My panties underneath? Absolutely drenched. I could smell myself the second I walked through the door, that warm, musky post-workout scent. Perfect.

Ryan’s door was cracked open. I could hear him playing some video game in there alone. I didn’t knock. I just pushed it open and stepped inside, still in my sweaty gym clothes, ponytail messy and my skin glistening.

He looked up from his desk and froze. “Emmy… hey. You’re back early.”

I closed the door behind me and locked it with a soft click. “Yeah. And I’m all sweaty from the gym. Figured it was time we picked up where we left off in the laundry room, don’t you think?”

His eyes went wide. He tried to play it cool but I could already see the bulge forming in his sweatpants. “I… uh… what do you mean?”

I smirked and walked right up to him, peeling my soaked gym shorts down my legs and stepping out of them. My black thong panties were stuck to my pussy, dark with sweat and a little wetter than just from working out. I dangled my ass right in front of his face.

“Sniff them, Ryan. Right now. I want you to smell how nasty I am after the gym. No touching yourself yet.”

He leaned forward like he couldn’t stop himself, nose pressing into the damp fabric. He inhaled deep, his eyes fluttering shut and let out this shaky little moan. “Fuck, Emmy… you smell so good.”

“Gross, right?” I laughed softly, but I was already getting wetter just watching him. “Your little stepsister’s sweaty gym panties and you’re sniffing them like a dog. Pathetic as always .”

I grabbed the back of his head and pushed his face harder into them, making him breathe me in while I kicked off my sneakers. Then I shoved him back onto his bed, climbed up, and straddled his chest.

“Hands behind your head,” I ordered. “You don’t get to stroke until I say so.”

He obeyed instantly, breathing fast. I slid forward until I was sitting right on his face, my sweaty, panty-covered pussy pressed against his mouth and nose. The heat from the gym was still radiating off me.

“Eat it,” I told him, grinding down slowly. “Lick your stepsister’s dirty, sweaty pussy through the panties first. Taste how worked up I got thinking about busting your balls again.”

Ryan groaned loud against me and started licking like he was starving. His tongue pressed flat against the soaked fabric, sucking the sweat and my juices right through it. I could feel him getting harder underneath me, his cock straining against his sweatpants.

I reached back with one hand, yanked his pants down just enough to free his dick, and gave it a couple slow, teasing strokes. “Mmm, already leaking again. Such a good boy.”

Then I started slapping his balls. Not too hard at first …just sharp little smacks with my palm while I rode his face. Each slap made his cock jump in my hand and his tongue work faster.

“Ow… fuck, Emmy,” he mumbled into my pussy, voice muffled. “I’m sorry… I know it’s weird…”

I laughed and slapped them harder, watching them turn pink. “Sorry for what? For getting rock hard while you eat your sweaty stepsister? Or for wanting me to hurt your balls again?”

I pulled my thong to the side and sat down fully, smothering him with my bare, slick pussy. His tongue dove straight in, licking deep and desperate, sucking on my clit while I kept slapping his swollen sack.

The sounds were so filthy. God…the wet lapping mixed with the sharp smack of my hand on his balls.

“Keep going,” I moaned, grinding harder. “And don’t you dare cum yet.”

I kept stroking him lightly, just enough to drive him crazy, while my other hand kept busting his balls in a steady rhythm. Slap… slap… slap. Sometimes I’d cup them and squeeze, sometimes I’d flick them with my fingers. Every time I hurt him he’d moan louder into my pussy and lick even more frantically.

“You like this, don’t you?” I teased with my voice breathy. “Getting your balls beaten while you tongue-fuck my sweaty pussy. You’re such a dirty little masochist.”

I slid one finger down between his cheeks, circling his tight little hole before pushing the tip inside. Ryan’s whole body jerked and he let out this broken whimper right against my clit.

“Oh my god,” I laughed, pushing my finger deeper. “You like that too? Finger in your ass while I slap your balls and ride your face? You’re even more fucked up than I thought.”

I started pumping my finger slowly, curling it just right while I kept slapping his balls harder and faster. His cock was throbbing in my other hand, leaking all over his stomach. I could feel him getting close.

“Don’t stop licking,” I ordered cause my thighs started to shake. “Make me cum and maybe I’ll let you finish.”

I rode his face harder, smothering him completely while my hand worked his balls and my finger fucked his ass.

The combination was too much for him. He started shaking, moaning desperately into my pussy and then he exploded. Thick ropes of cum shooting all over his chest and stomach without me even stroking him anymore. Just pure ball-busting, facesitting and prostate play pushing him over the edge.

I came right after, grinding down on his tongue and flooding his mouth with my juices while I gave his poor balls one last firm slap.

When I finally climbed off, he was a wrecked, panting mess. His face shiny with my sweat and cum, chest covered in his own load, balls bright red and sore.

I wiped my finger on his shirt and smiled down at him sweetly.

“Clean yourself up, loser. And next time I come back from the gym? I expect you to be waiting on your knees with your hands behind your back. Got it?”

Ryan nodded weakly, still catching his breath, that shy, satisfied little smile on his face again.

“Anything you want, Emmy.”
