The dressingroom mirror was fogged with their breath.
Laura's back pressed against the glass, latex peeled open like a wound, breasts red and swollen from Alex's brutal grip. Her pussy glistened under the pink lights: slick, swollen, begging.
Alex's control was gone.
He grabbed her jaw: hard: forcing her mouth open. Two fingers shoved inside her pussy without warning: deep, rough.
Laura's eyes rolled back.
A sharp, broken gasp tore from her throat as her walls clenched around the sudden invasion. "Fuck....Alex...."
He didn't speak.
He pumped: fast, merciless, curling his fingers to hit that spot inside her that made her knees buckle. The wet, obscene sounds of her pussy filled the tiny room: schlickschlickschlick. Her juices coated his hand, dripping down his wrist, pooling on the bench. Laura's hands clawed at his shoulders, nails digging through his shirt.
Her hips bucked wildly, chasing his fingers. "Yes....yes....harder....don't stop...."
Alex added a third finger: stretching her.
Her pussy sucked him in, fluttering, desperate. He twisted his wrist, thumb grinding her clit in brutal circles.
Laura's moans turned to sobs: "I'm....gonna....Alex....please...."
He didn't let up.
He fucked her with his fingers like he wanted to ruin her. Her thighs trembled. Her back arched off the mirror.
Then she broke.
A guttural cry ripped from her as she came: hard. Her pussy gushed around his fingers: hot, wet, pulsing. Juices squirted down his forearm, splattering the latex, the bench, the floor. Her whole body convulsed, legs giving out: only his hand inside her and his grip on her jaw holding her up.
Alex pulled his fingers out slowly: slick, shining.
Laura's knees buckled. She collapsed forward into his chest, panting, shaking.
He released her mouth.
Laura attacked his lips.
No hesitation.
She kissed him like she was starving: tongue shoving into his mouth, teeth clashing, sucking his lower lip until it bruised. Her hands fisted his hair, yanking him down to her level.
She tasted like sex and desperation: moaning into his mouth with every breath, grinding her soaked pussy against his thigh like she wanted to climb inside him.
Alex kissed back: brutal.
One hand tangled in her hair, the other smearing her cum across her lower back as he pulled her closer. Their tongues fought for dominance: wet, messy, filthy. She bit his tongue. He growled and bit her lip harder.
Laura broke the kiss with a gasp, eyes wild.
She dropped to her knees: instantly.
Her hands tore at his belt, zipper: desperate. His cock sprang free: huge, rockhard, veins pulsing, precum dripping from the slit.
Laura's breath hitched. "Fuck....Alex....it's...."
She didn't finish.
She licked: one long, slow stripe from balls to tip, tongue swirling around the head, collecting his precum like it was candy.
Then she sucked: lips stretching wide, taking the head into her hot, wet mouth. She couldn't take it all: gagging when he hit the back of her throat: but she tried, eyes watering, mascara running.
Alex's pleasure was whitehot.
Her mouth was heaven: tight, wet, eager. Every suck sent lightning up his spine. Her tongue swirled under the head, teasing the sensitive spot until his thighs shook. She hummed: vibrations shooting through his cock, making his balls tighten.
He couldn't take it.
Alex grabbed her head: both hands: and fucked her mouth. Slow at first: then harder. He used her like a toy: hips snapping, cock sliding in and out of her stretched lips. Laura moaned around him: gagging, drooling, loving it. Tears streamed down her cheeks, but her hands gripped his thighs, pulling him deeper.
He pressed her head flush against his pelvis: buried. His cock pulsed down her throat. He came with a guttural roar: thick, hot, endless. Rope after rope shot straight into her stomach.
Laura swallowed frantically: throat working around him, milking every drop.
When he finished, he pulled out slowly. His cock slipped from her lips with a wet pop.
Laura gasped for air: coughing, drooling, cum and saliva dripping down her chin onto her exposed tits.
Alex came to his senses like a slap.
He stumbled back, dick still hard, horror flooding his veins. "I'm sorry....Laura....sorry....that was wrong....that was so fucking wrong...."
Laura wiped her mouth with the back of her hand, voice hoarse. "It's not, Alex. Alex!"
He shoved his cock back into his pants, zipping up with shaking hands.
He couldn't look at her.
He bolted out of the dressing room: leaving her on her knees, cumstreaked, wrecked.
They bought the four dresses in silence. Alex paid with Mark's card like a robot.
Laura didn't speak. Didn't look at him.
In the car, the silence was deafening.
Laura finally broke it: voice small, cracked. "What happened back there, Alex? We just had fun. And you…"
"That wasn't fun, Laura!" His voice cracked like glass. "It was wrong. You're my sister."
"Stepsister!"
"YES! A SISTER! We shouldn't....fuck....we can't do that!"
Laura laughed: bitter, broken. "Ah. Postnut clarity."
"Laura, what is wrong is wrong. I'm sorry. I wasn't in my senses. From now on: keep a distance from me."
Her eyes flashed. "So it was wrong, and you forced your sister into a sexual act, huh?"
"Laura....I'm sorry, Laura. I really am. It was wrong. We should keep distance from each other."
Laura's voice filled with tears: shaking, raw. "What about me, Alex? What about my feelings? I'm not a slut, you know! I don't go around seducing men! I've never had a boyfriend before. This is the first time I've fallen for someone. I fell for you, Alex! And you used me: then tossed me like I'm some whore! Why did you care for me? If you didn't, I would've fallen for some loser like you!"
Alex reached for her: voice breaking. "Laura, I...."
"You what? What do you want to say, huh? You're my brother? Who the fuck are you, Alex? How the fuck are you my brother?!"
"Our parents...."
"Your dad and my mom married each other. What's that got to do with me? I didn't wish for you to be my brother so I could fuck you!"
Alex tried to touch her shoulder. "Laura, calm down...."
"Don't touch me! tell me: if I'm your sister and all this is wrong to you, then why the fuck do you get aroused because of me?! You want to fuck your sister that badly, huh?!"
"Laura, listen...."
"Shut the fuck up. Don't touch me."
She threw the door open, grabbed her bags, and stormed out.
Hailed a taxi. Got in.
Alex followed the taxi the whole way home: heart in his throat, knuckles white on the wheel.
The taxi stopped in front of their house. Laura paid, slammed the door, and disappeared inside without looking back.
Alex sat in the driveway, engine running.
He punched the steering wheel: once, twice, three times. Blood smeared the leather.
He whispered to the empty car: "What the fuck have I done?"
