My fingers were buried deep inside my soaked pussy when my sister's voice cut through the door like a knife.
I gasped hard and bit my lip to stay quiet. My back pressed against the cool bathroom tiles as I sat on the edge of the tub with my legs spread wide. My baggy sleep shirt was pushed up over my heavy tits and my shorts lay crumpled on the floor. I had two fingers pumping fast in and out of my dripping cunt while my thumb rubbed tight circles on my swollen clit.
"Fuck... Jax," I whispered under my breath. In my head he had me bent over the sink, his strong hands gripping my hips while he slammed into me from behind. I pictured his tattooed arms flexing and his deep voice growling my name instead of hers. My pussy clenched hard around my fingers as I added a third one, stretching myself open.
The fantasy felt so real. I could almost feel his thick cock filling me up, pounding me until I could not think straight. My juices ran down my thighs onto the tub edge. I rubbed my clit faster, pinching my hard nipple with my free hand. My body trembled. The pressure built so fast I knew I was close.
"Harley! You in there? Hurry up or I'm leaving without you!" Ruby shouted from the hallway. Her heels clicked on the wooden floor right outside the door.
Shit. I froze for half a second but my body did not want to stop. I kept rubbing my clit in quick desperate circles. "Almost done!" I called back, my voice shaky. "Give me two minutes."
I closed my eyes again and went harder. In my mind Jax had me on my knees sucking his cock while Ruby was out somewhere. I imagined his hand in my hair and his rough groan as he came down my throat. That dirty thought pushed me over. My pussy spasmed hard around my fingers. I came so strong my legs shook and a tiny moan slipped out before I could catch it.
I sat there breathing fast for a few seconds, my fingers still inside me feeling the aftershocks. My juices glistened on my hand. I quickly wiped myself clean with some toilet paper and washed my hands. My face was flushed pink in the mirror. I looked at my messy blonde hair and plain face behind my glasses. Nobody would guess what I had just done.
"Harley Quinn, I swear if you make me late again," Ruby yelled.
"I'm coming!" I yanked my baggy hoodie and loose jeans from the hook and pulled them on fast. The clothes hid every curve I actually had. No makeup. Just my glasses and my usual plain self. I took one last look in the mirror then opened the door.
Ruby stood right there in a tight red dress that hugged her body perfectly. Her bright red hair fell in sexy waves down her back. She looked hot as hell and she knew it. Jax leaned against the wall beside her checking his phone.
"Took you long enough," Ruby said rolling her eyes. "What were you doing in there, dying?"
"Sorry," I mumbled. "Just... morning stuff."
Jax glanced up and gave me a small polite smile. "Morning, Harley."
His voice hit me right in the stomach. Deep and smooth. I felt fresh heat between my legs even though I just came. "Morning, Jax," I said trying to sound normal.
Ruby grabbed his shirt and pulled him into a quick kiss right in front of me. I should have looked away but I could not. Her body pressed tight against his. His hand slid down to squeeze her ass as their mouths moved together. The kiss was wet and hungry. Ruby made a little moan and rubbed herself against him like they were alone.
I stood there frozen watching. My twin sister kissed the man I fantasized about every single night. Jax's fingers dug into her dress the same way I imagined he would touch me. When they finally broke apart Ruby smirked at him.
"Missed you last night, baby," she said in that flirty voice she used on everyone. "You better come over after work. I need you."
Jax chuckled low. "Yeah? You gonna wear that dress for me?"
"Maybe. Or maybe nothing at all." She winked and ran her hand down his chest.
I cleared my throat and looked at the floor. My cheeks burned. "We should probably get going. Traffic gets bad."
Ruby laughed. "Always so responsible, Harley. What would I do without my boring little twin?"
She said it like a joke but the words stung. I forced a small smile. "Guess you would be late every day."
Jax glanced between us. "You two ready? I can drop you both off if you want."
"That would be great," Ruby said grabbing his arm. "Harley, you coming or what?"
We walked outside together. Ruby kept talking the whole time. "So Jax and I went to that new club last weekend. You should have seen it. Everyone kept buying us drinks. This one guy would not stop staring at me. Right babe?"
Jax nodded. "Yeah it was packed."
I stayed quiet mostly listening to them. Every laugh Ruby let out and every time she touched Jax made my stomach twist. I kept remembering how she sounded on the phone yesterday when I overheard her talking to her friends.
"Harley is so weird sometimes," she had said. "Always hiding in her room. I swear she is jealous but too scared to do anything about it. Poor thing will never get laid looking like a walking laundry basket."
Her friends had laughed. I had stood outside her door feeling sick.
Now watching her press against Jax in the front seat of his car I felt that anger rise again. She had everything. The body, the confidence, the man. And she still talked shit about me.
"You okay back there?" Jax asked looking at me in the rearview mirror.
I met his eyes for a second. "Yeah. Just tired."
Ruby turned around. "You should come out with us sometime. Maybe put on real clothes for once. I could do your makeup. Bet you would look decent if you tried."
"Thanks," I said keeping my voice even. "Maybe."
Inside my head the fantasy played again. Me in Ruby's red dress with my hair dyed. Jax looking at me like he wanted to devour me. My pussy throbbed at the thought. The urge was already building again even after what I did in the bathroom.
We pulled up to my office building first. Ruby leaned over and kissed Jax again. This time longer and deeper. I could hear the soft sounds of their mouths and her happy sigh.
"See you later, handsome," she whispered loud enough for me to hear.
"Later," he answered.
I grabbed my bag and stepped out. "Thanks for the ride, Jax."
"Anytime, Harley."
Ruby waved from the car. "Don't work too hard, sis!"
As they drove off I stood on the sidewalk for a moment. My heart pounded hard. The anger mixed with that deep hungry ache between my legs. I had spent years hiding and touching myself while thinking about him.
Today something felt different. The idea that started forming in the bathroom would not leave me alone. Dye my hair red. Wear her clothes. Take what I wanted for one night.
I walked into the building with my head down but my mind racing. For the first time I wondered what it would feel like to be the sister everyone wanted. To have Jax look at me the way he looked at her. To finally let my dirty urges out instead of locking them away.
The day dragged but every spare second I thought about it. By lunch I had already searched how long temporary red hair dye lasts. By the time I got home that evening the plan felt less crazy and more necessary.
Ruby was out when I got back. Her room door stood open showing all her sexy outfits hanging up. I stood in the doorway staring at them. My fingers itched to touch the soft fabrics.
I stepped inside and picked up a tight black dress she wore last week. It smelled like her perfume. My pulse quickened. I held it against my body in front of her mirror. The girl looking back had the same face but hidden under baggy clothes and fear.
Tonight I would not be her anymore. Not in my fantasies at least.
I locked myself in my room and lay on the bed. My hand slipped under my waistband again as I pictured Jax's face. This time I did not feel guilty. This time the fantasy had a plan.
"Ruby is out with friends," I whispered to myself as my fingers found my wet pussy again. "And I'm going to borrow her boyfriend."
I came hard thinking about it. Faster and stronger than the bathroom orgasm. My whole body shook with need. When I finished I stared at the ceiling breathing heavy.
Tomorrow I would dye my hair.
Tomorrow I would become her for one night.
And I would finally fuck the man I had wanted for so long.
The thought made me smile in the dark. For once I did not feel shy. I felt powerful. Hungry. Ready.
I got up and started planning every detail. The dress. The makeup. The way I would kiss him first. The way I would moan his name when he finally pushed inside me.
My twin had no idea what was coming. And neither did Jax.
But I could not wait.
