*****

It was morning. Thursday. My alarm was going off. I turned it off and rolled over. My erection was throbbing. I listened for my sister. Nothing. I lay for several minutes before getting up. I was naked, I was sleeping in the nude now. I couldn't tear the images of yesterday out of my mind. My member wouldn't retreat. I headed toward the bathroom. Still no sounds. I was about to knock but figured she might be sleeping in. Yesterday was a... tiring day. I was a bit disappointed but figured she might need time. I headed in for my shower.

-------------

The door to the shower closed and I heard the water start. I was soaking myself already. I wanted this moment to be perfect. I had texted Mom just after she left for work asking if I could use her white heels today. At first my Mother was shocked I would ask to borrow heels. I never wore heels, but then repeatedly told me she didn't mind and I should have fun. Today would indeed be fun.

With his shower running I darted downstairs in my tiny summer dress. I flew into our parent's room and began hunting for through her shoes. Bingo, found them. Our Mother and I had nearly identical sized and proportioned bodies. Mom was very pretty, her waist a bit thicker than mine due to her age but not by much. Her breasts were fuller and larger than mine, but overall she had weathered the storm of two children pretty well.

With the 5 inch heels in hand I was about to run up and paused. I had debated this all night, I had barely slept. Her dresser was next to me. I finally decided to do it. I opened her top drawer, the personal one. She had so many beautiful lace panties, boy shorts, thongs, G-strings... I was jealous. I grabbed a beautiful mesh white thong to match my dress. The mesh went very low into the crotch, it was devilishly sexual in design.

I ran back upstairs, he wouldn't be much longer. I slipped my panties off and slid on the thong. It felt amazing. I felt so slutty. The cheeks of my ass constantly felt the sway of the dress. I felt very exposed and I loved it. I slipped the heels on and tossed my wet panties on my bed. I stepped out, unsteady on these high heels. This would take some practice. I sat down at my desk and put my glasses on, then my headset. I turned up some slow music and crossed my legs. The water turned off...

-------------

She was sitting cross legged at her desk as I walked out of the shower. She wasn't there before I went into my shower but now she sat there. What was she wearing? Her glasses adorned over her face, her wireless headset over her head. She swung her naked leg, exposed up to her hip, to the tune of an unheard song.

She was wearing a summer dress that was entirely too short. I could see her milky white thighs from the side and her breasts bulging from the top of something so tiny. She wore heels, not short heels but tall sexual heels as she danced her leg to the sound of the music. I couldn't move, I couldn't believe what I was seeing, I couldn't believe this was my sister. I was wearing nothing but a towel.

"Hey Joe"

She looked over as if nothing was special, as if nothing was out of the ordinary. She said it like the thousand times it has happened in the past but today was not ordinary. She was not dressed like any other day I had seen her in my entire life. Her legs, my God, they were incredible. My jaw was on the floor.

"Hey... ummm... April..."

I barely choked it out. She was swaying her leg back and forth looking something that was more angelic than my sister. My member began to harden at the sight of her sexy legs. Our relationship was changing so fast I could barely comprehend it. Now she sat here, not like the conservative girl I grew up with, but a very sexy woman whom my loins could not deny.

She swung her chair over to face me. Her legs seemed to be endless at the length only terminating at the sexy heels she wore. She slowly took off her headset which was streaming music. Her breasts strained against the thin material, her tiny nipples very discernable. I couldn't restrain myself, I was hard in a very bad way but she pretended not to notice as I stood there with nothing but a towel and a tent protruding from my towel aimed directly at her.

"Can you take me to the mall today? I was hoping we could go shopping..."

Her voice was deeper than usual, sexier than usual. She trailed off seeming much different than the usual request. I had a car but she didn't. We always went everywhere together so one car was more than sufficient. I couldn't say no. I wouldn't say no, how could I deny her?

"Yeah... ummm, sure... when do you...?"

She smiled, that beautiful smile that I had come to know so well as her legs swayed with a music she no longer listened too.

"Whenever you're ready big brother..."

Big brother? She never called me that. She sat there swinging her leg seductively as my erection pressed against my towel. In a fog, I walked to my room and threw on some shorts and a shirt. I don't know why but I skipped the boxers. My urges becoming more powerful than I could control. With an erection pressing against my shorts, I loaded my pockets with my wallet and keys. Time to go...

-------------

He opened the door for me. He never does that. He led me to the right side of his vehicle and opened the door. I stepped in making a show of my legs. I stepped in, one leg at a time. The spread of my legs lifted my dress as planned. I wanted him to see as much as possible and the show didn't disappoint. He even caught a glimpse of my Mom's white mesh thong barely covering my sex. I could see his visual discomfort as he sat down in the driver's seat. He was hard, very hard. I knew he would be happy but now was not the time to give in. We had to stay mostly focused.

During the ride, I caught him stealing looks at my legs. It made me feel good to know my brother thought my body was attractive. I felt myself moistening to his looks. I was wearing my Mother's panties without her knowledge so my crime added to my arousal. I was quickly soaking the thin cloth covering my womanhood. I looked over at him, we were stopped at a light. He was obviously staring at the generous display of my legs.

"Do you... like them... my legs?"

I asked sultry and seductive. Our car ride had be silent up until now. He turned red. In response to his silence I spread my legs and lifted my dress. He could now see Mom's panties.

"I don't mind... that you like... my body... anytime you want to look..."

He groaned. His erection pressing painfully against his shorts.

For all my strength I was still weak. I wanted him to be happy but when it came to finalizing our relationship I was powerless. I wanted him to want me so bad. His desire for me fueled my actions. The light changed to green and we started moving again. He was hard. I could see his shorts straining to keep his member in. We arrived at the mall shortly after. I told him to park in the parking garage. It was early and the mall hadn't even opened yet. The garage was empty, he parked on the second floor in the back. The car stopped, the engine went silent. He looked over at me expectantly.

I shifted in my seat so my back was to the door. I lifted my left leg onto the seat fully exposing my panties to him. He groaned.

"You know... you can masturbate to me, anytime..."

He could only groan my name as I he looked at the material, soaked between my legs.

"I was hoping... maybe... you would... if you don't mind..."

My voice had dropped and was sultry. He was silent as he nodded. He gaze locked onto my crotch and legs.

"Would you... take it out...?"

He dropped his hands to his lap and unzipped his shorts. His cock, looking painful, sprung into view. The head of his member deep purple, circumcised and thick. He reached his hand to his member. I begged...

"Please don't... wait... I promise, it's worth it..."

He paused. Leaving his member bobbing to the pace of his heartrate.

"I can... cum... without touching myself... down there... my nipples..."

I was softly kneading my breasts, stroking my nipples. His gaze shifted to my chest as a cupped and pulled on my tits through the material. My fingers stroked my nipples which pressed visibly against the thin dress. His cock seemed to grow even larger as he watched me masturbate to the sight of his member.

"Take off your shirt..."

I was begging. I wanted to touch him. My orgasm was approaching as I stimulated my nipples. He didn't hesitate. His shirt flew off in one swift motion. I kept my right hand on my right breast and reached out to his chest.

"Some guys have... sensitive nipples..."

I began teasing his right nipple with my left hand. Touching him, listening to him groan in pleasure. His hips were thrusting upwards and I was getting very close. I reached down with my left hand and coated my fingers with the sticky white fluids flowing from me.

"Oh God, April, I might..."

My fingers, slick with my fluids began rubbing his nipple. He loved it. His thrusting quickened and my orgasm was about to strike. I stopped stimulating him, staring at his bobbing cock as it thrust wildly into the air. I began to cum. The fluids flowed freely from my shaved sex into my Mother's panties. The feel of the mesh against me as I stroked my nipples overwhelmed me. I began to spasm as wave after wave hit me. I began flooding my Mother's panties. The mesh oozed my juices through onto my legs and the car seat.

His eyes were begging for release, he stayed faithful and kept his hands by his side. Precum soaking his member as he watched me complete my orgasm and sit there, exposed to his view. The panties were nearly transparent now, soaked in my desire.

I slowly began to recover and remembered my plan. The clock read 10:02. The mall had just opened. It was time.

I shifted in my seat back to a normal position. His eyes never leaving my breasts. A thin bead of sweat had formed on me from my public display of masturbation. I pulled the handle on the door to release it, as the door swung wide I made a very slow display of stepping out, bent over. His view locked onto the fluids coating my crotch with thin trails dripping down my legs.

He was breathing heavy as I stepped over to his side of the car. I opened his door, his member still standing tall, needing release. My left hand reached down towards his member.

"April, no... you shouldn't touch it..."

I gave him a lover's smile as I took it in my hand. It was incredibly hard, solid and warm. My small hands wrapped around his shaft, careful to avoid touching the sensitive head. He groaned feeling my hands wrap around his length. I slowly tucked it into his shorts and zipped him up. He looked confused. He took my hand and left the car. His shorts painfully holding in his erection he put his shirt back on. I pressed my body tightly against him, feeling his rock solid cock against me, and spoke directly in his ear.

"I promise, you won't be disappointed..."

He groaned and locked the car...

I led him into the department store hand-in-hand with a vague idea of what I was looking for. I wanted a dress, a slutty dress, something I never owned before. The department store was empty at this time in the morning but specifically offered very petite clothing for size 00 women.

Everything was tiny, we traveled rack to rack as I looked for the perfect item. I often bent over with him behind me, his member never getting a break. With no one around, I would rub my ass against his bulge to keep the tension on his member. More than once, he watched my bare ass press against him and slide side-to-side. Each time I felt his shorts renew the wetness from the tip of his dick. As we sorted through the options, a small black dress struck my interest.

It was short but not too short. It had spaghetti straps deep down the back and was very low cut in the front. My cleavage would be well displayed, the cut in the dress ended just above the waist. I lifted this dress from the rack and pressed it against my chest. He was staring at me lustfully. This was it, I knew it. Hand-in-hand I brought him to the dressing room.

"Wait here... trust me..."

I kissed him on the cheek.

"It'll be worth the wait..."

He looked at me wanton, I disappeared into the changing room. Once inside I quickly removed my dress and dropped my Mom's panties. They were already soaked from my earlier orgasm. I put on the black dress which cut so deeply in the back, the top of my ass was on full display. The front's deep cut allowed my perky breast to display considerable side boob. This was it... I stepped out and approached my brother. He was doing the normal guy thing and pretending to look at random clothes around the dressing room entrance.

When he looked up and saw me, his mouth dropped to the floor. The low cut up front exposed my breasts in a way he'd never seen. The shortness of the dress exposed my long legs which were extenuated by the heels I wore. I turned around, the top of my ass exposed, the part in my cheeks proof of my nudity underneath. I approached him, his erection still pressing against his shorts. My steps were slow and meticulous, I swayed my hips and pressed my chest out to the point I could bare breath.

"Oh April..."

He couldn't tear his eyes off me. I was incredibly excited now. My womanly liquids began consolidating and dripping down my legs. This was the plan, I had executed perfectly. Hesitation filled me for some unknown reason, was this too much? Would he take the bait? I embraced him, my right leg between his, pressing against his manhood. I leaned in, my nipples straining against the material. My breath, rapid on his neck, I look up and spoke just inches from his ear.

"I... need your help..."

It was barely more than a whisper. My anxiety consuming me. My closed hand meeting his, he opened his hand instinctively. My Mother's panties, soaked with my juices, lay between our hands now. It was confirmation that I was wearing nothing under this tiny dress.

His eye widened. Slowly I led him by the hand into the dressing room. We said nothing as we closed the door behind us. The room was tiny. I turned to him, our bodies pressed against one another. His hand wandering the skin of my back through the straps of the dress.

My hands reached down, his erection straining. I unbuckled his belt and ever so slowly lowered his fly. His erection still constrained I reached in, the heat emanating from his member guided me. I released the steel between his legs. It jumped up and slapped up, raising the dress and contacting my wet slit. I kept it there for several minutes letting him feel the moisture dripping down, directly onto his cock. We stayed like this for several minutes, my moisture coating his sensitive head. Finally I back away...

"Could you... put them on... for me...?"

I dangled my right leg out for him. He dropped down, with my leg raised, he had a clean view, unobstructed to my newly shaved pussy. I lifted my dress so he could see everything. He was just staring up between my legs, watching the sticky white fluid ever so slowly ooze from my snatch. Cautiously he slid the first side of our Mom's panties over my Mom's heels onto my leg. I moved my right foot to his member and began rubbing it with her heels. His precum began coating the straps and my skin. He slowly worked the material up my leg, careful not to touch me.

"You can touch... my leg... if you want..."

He moaned loudly. His hand slowly began stroking my smooth shaved legs as our Mom's heels stroked up and down his member. Finally, I lowered my right leg and offered my left. He stroked my leg with his hand ever so softly as my left leg continued rubbing him from the other side. The coating of his precum on my feet and the straps of the heels was thick and sticky. I could feel his precum soaking my foot, the straps of the heels, his cock twitching as my foot slid up and down on the underside of his member. The material of the straps glistened with his juices. He placed my left leg into the panty and began working them up my body.

As the panties slowly slid up my legs, I lowered my left leg to give him full access. I wanted him to save his orgasm for the final act. He was close now.

His hands were soft when touching me. No part of my legs went untouched as his hands worked the panties up my legs. I couldn't help myself, my voice deeper than it had ever been in my life. "You like touching me don't you? Touching me while you look at pussy as it creams for your cock."

His moans became louder, just the touch of my body was about to throw him over the edge. He paused, his hand lifted the backside of the panties slowly over my ass. My flesh sliding against his bare touch.

"Grab my ass, feel me... big brother..."

He softly grabbed and kneaded my flesh as he rose to his feet. After what seemed like an eternity of his sexual touch, he hesitantly reached to the front of the panties and pulled them tight. I pulled him close, so that his member pressed tightly against the panties he just put on me. I could feel the head of his cock straining against my sex, lubricated by his precum and the fluids soaking the panties I wore. His hips began moving slowly, ready for his orgasm.

"Did you... like my... show...?"

He groaned and nodded barely able to contain himself. His hips slowly thrusting between my legs. I brought my legs together, enveloping his member between my thighs. They were slick with my juices and his rhythm indicated he was there, ready to spray his seed all over me. Not yet though, it wasn't time.

I opened my legs, releasing his member and stepped back. Slower than I ever moved, turned around with him behind me. I slipped the black dress over my head bending over and giving him a full display of the ass he just groped. I felt his member poke the flesh of my ass and the precum spilling from the tip of his cock. I kept him at the edge, ready to cum as I pulled my summer dress back on. Rubbing my ass against him as I squirmed back in to the tiny thing. I went slow and deliberate with my motions wanting to give him ample opportunity to rub his cock on my flesh without orgasm.

I kept my dress up and my panties exposed as I turned around and pressed against him. His member, literally spewing precum, pressed up against my stomach.

"You can... cum... here..."

He looked down, past my breasts to where I held my panties open from the top. He slowly aimed his member toward the gap I made between my stomach and the top of the panties. My thumb holding the interior of the material as his steel slipped between the panty and my stomach. My bare skin rubbing against him from both sides. I could see the fire in his eyes as he felt my stomach give way to my clitoris and further, my soaking wet vulva. My right hand held the panty in place until his member fully rested between the lips of my womanhood. With my entire hand, through the mesh material, I wrapped my fingers around his length.

"April... no... you shouldn't... touch it like that..." The head of his cock was now directly receiving the fluids leaking from my pussy. His words were betrayed by his lust. His cock never withdrew, it was time for my brother to cum. My hand slowly began stroking his member through the sexy mesh material.

"I want this... so bad..."

I was whispering in his ear. Our bodies pressed against one another. My hand moved up and down his cock slowly. I felt his cock begin to expand, his semen fully loaded. His was about to cum. I stopped stroking and leaned into his ear.

"Do you like these... panties?"

I asked barely more than a whisper. He nodded. I wanted the final act to be perfect. I was so horny. I had fantasized about this and it was about to happen. My brother's cock would spray his seed directly onto my wanton sex.
