She had recently moved back home after getting herself into financial difficulties. It was only supposed to be for a few weeks, but that was nearly 4 months ago. I was 19 years old and bored with nothing to do, as I wandered around the house aimlessly. Making my way upstairs, I noticed the door to Julie's bedroom was ajar. I knew she was not home so being a curious type of guy I decided to have a nosey. Julie's room looked like a bomb had hit it, with clothes and shoes scattered everywhere, left where she had dropped them. Even her bed was still unmade with her quilt half discarded on the floor with her nightdress. The air was heavy with a mixture of her perfumes reminding me of the smells you found at the perfume counter in a department store, just like a tart's boudoir. I sat on Julie's bed looking around her room, taking in the atmosphere before lying down on her bed slowly breathing my sister's scent. After five or ten minutes I moved to her dressing table, and examined all her little trinkets in the little pots that she kept, before I found myself drawn to a drawer which had been left half open. This was where she kept her bras, panties, and all other items of underwear; it was full to bursting... I felt like a small child in a sweet shop as I rummaged through her drawers. I had always had an unusual interest in women's underwear particularly in the lacy and see-through variety which made women look pretty and feminine. Lacy wired bras and bustiers were a particular favourite of mine together with stockings, suspenders and of course the matching g-strings and thongs. Julie was obviously of the same mind as myself, for her drawers were crammed full of beautiful underwear in an array of different colours. As I searched I pulled one of her black lacy under-wired bras out. It felt so stiff and uncomfortable and I wondered whether it hurt the soft skin of her breasts. I thought that even if they were uncomfortable, it was still worth wearing as they looked so sexy. Holding it to my nose, I breathed in, deeply savouring the pleasant aroma of Julie. It was beautiful and my mind fantasized just how Julie looked when she wore this bra. I daydreamed about myself dressed in her sexy underwear and how it would feel wearing such pretty underwear and concluded that girls were so lucky. I replaced the bra and continued to rummage through her drawer, when I found a pair of black see-through skimpy panties. I nervously held them to my nose as I'd done earlier with the bra, inhaling deeply any smell there might have been of Julie. At the same time as I was rummaging through her underwear, I became aware of the huge bulge beneath my jeans as my cock had slowly become aroused, and was now straining to be released from the confines of my jeans. Without thinking I quickly threw off my sweatshirt, and in two swift movements I had unzipped my jeans and pulled them down until they had settled around my ankles. I stepped out, kicking them aside before removing my socks. I stood in front of her mirror totally naked aroused and excited. I began to fondle myself as my huge swollen erection stood upright like a huge stiff flag pole. I wasn't particularly large, probably only six inches, but quite thick around the girth, and my purple swollen, shiny head felt like it was going to explode. I went back to Julie's knicker drawer and rummaging through I selected a black lace bustier with a tiny matching lace g-string, and a pair of black stockings before sitting on her dresser chair; I had decided that while no-one was about, now would be a good a time as any to live out a fantasy I had been keeping for years. I began to fasten the bustier around my body. I struggled to fasten the tiny hooks and eyes, before adjusting the bustier making sure it was positioned properly. Then, stepping into the tiny g-string I pulled it up around my hips and positioned it comfortably between my cheeks before trying to cover my swollen cock with the tiny patch of lace. It only managed to cover my balls with my swollen erection completely exposed. Once I had slipped the stockings on, I stood in front of her mirror and admired myself but couldn't help but smile... I looked ridiculous with my balls hanging out at either side of the g-string and my swollen cock standing tall and erect. I felt so horny, so sexy and so naughty! Here I was dressed in my sister's sexy underwear alone in her room. I moved over to Julie's bed propping myself up on her pillow, before wrapping my fingers around my thick cock, and slowly but deliberately I began to masturbate. Up and down I moved my hand in a slow twisting motion, paying particular attention to the top of my swollen head, then slowly speeding up until I was furiously masturbating my erection. After a few minutes, my body stiffened, and I closed my eyes as I let out a loud howl before thrusting my pelvis high off the bed and releasing three large jets of thick creamy cum. I continued to masturbate my erection, trying to extract any remaining globules of semen from the bowels of my balls, but only managing to encourage two small further globules before my swollen erection finally began to die on me. I looked down at my spent cock and the small pool of semen that had landed on Julie's bustier and thoughtfully dragged my finger through my sticky mess. It was thick and warm. Without thinking I raised my finger to my mouth licking and sucking it clean before helping myself to more. This time I used both fingers to wipe my cum off Julie's bustier before placing it back in my mouth and sucking it clean. I felt horny and randy like the dirty slut I was while half asleep on Julie's bed, exhausted and spent. I hadn't noticed in my excitement that someone else had entered the house while I was slowly recovering. When to my sheer horror the door opened and Julie appeared at the door. In a split second, I rolled off the bed and landed in a heap on the floor cowering behind Julie's bed, while she glared at me. I looked up from behind the bed to see my older sister, Julie stood in the doorway glaring down on me. She tossed her long auburn hair out of her face as a big smile crept up on her face as she realised my predicament. She took one look at me hiding behind her bed then, looking in her mirrored doors she saw I was dressed in her underwear, and laughed. I begged her not to come any further in the room, but all my pleading was in vain. She strode straight in and standing directly above her bed, glared down at me. "What the fuck are you up to, Steve? What are you doing hiding behind my bed wearing my undies?" I desperately pleaded once more for her to leave her bedroom. I was almost in tears as I pleaded, "Please Julie... just leave the room for a minute..." Instead of leaving the room she walked around her bed and stared down at me with a huge grin on her face before telling me to get up. By now I was almost in tears, caught out in the most private of acts. How could I have been so careless? Whatever made me do this in my own sister's bedroom? I slowly stood up, holding my hands in front of my by now very flaccid cock, waiting for Julie's abuse but instead of abuse, she ordered me "Move your hands and let me see my little brother in my underwear. Why have you been wearing my underwear Steve? Does it turn you on?" She teased. Sheer horror engulfed me. "Please Julie...don't say anything to anyone. I didn't mean any harm I... just couldn't resist having a look, and you know one thing just led to another... I just couldn't resist trying them on." "Well that's not all you've done with my undies, have you?" she sneered, pointing at the wet patch that was quite visible on the bustier. "I'll get them cleaned Julie but... please don't tell," I pleaded. Julie smiled and with and evil glint in her eye she ordered me to parade up and down the room modelling her underwear. She enjoyed watching me squirm and began to milk it for all it was worth; every now and again she would order me to stop and give a twirl before ordering me to continue. "Swing your hips from side to side and try to look sexy darling... I'm not going to bite so please stop looking so scared!" I gave her a sarcastic smile before continuing to strut back and forth before her. I exaggerated the swinging off my hips like the models do on a catwalk, and as I brushed past Julie she slapped me on my backside causing me to wince. "You're good at this," she giggled. Patting the bed beside her she motioned for me to come and sit. "Now why don't you come and sit with me? I want to watch you jerk yourself off." She ordered with a big smile on her face. "Please, please... don't make me do this Julie." I pleaded desperately. "If you don't show me, then as soon as mum and dad come home I'm going to tell them what you've been up to!" Julie replied tersely. I looked Julie in the eye, only to see her determination. "Please Julie don't..." "Start jerking Steve!" Her voice a little more threatening now. I reluctantly reached for my flaccid penis and slowly began to squeeze and massage it until it slowly came back to life. Bit by bit it began to jerk and twitch as it came to life. As it slowly became erect I began to slide my hand backwards and forwards in a slow gentle movement until it was fully erect, with its shiny purple swollen head as large as it had ever been. I spat on my hand and lubricated my swollen cock while increasing my tempo, faster and faster as Julie urged me on. "Come on, I want to see you cum for me little brother," She teased. My breathing was becoming heavy and laboured as my moans, grunts and gasps became louder and louder; no longer was I scared or nervous. I was excited and horny and with Julie urging me on it was a huge turn on. "Ah, ah... fuck, fuck, I'm going to cum..." I spluttered. Julie was smiling, enjoying my performance while at the same time taunting me with her raunchy comments. "I want to see you cum, Steve... Let's see how far you can shoot your load." I was now furiously stroking my cock as fast as I could. The bed was creaking and squeaking as I thrust my hips up and down, bouncing on the bed. "Oh, oh...fuck, fuck...oh, oh...ah, ah..." I eventually reached the point of no return, before clenching my teeth, shutting my eyes, and grunting. Two small thick spurts of cum shot out from my swollen cock and once again I'd managed to soil Julie's bustier with my thick white sticky cum. She let out a shrill gasp of delight as my cock erupted before her eyes and reaching out she quickly scooped a globule of my warm sticky cum off her bustier before slowly slipping her finger inside her mouth. Looking me straight in the eye she sucked it clean before withdrawing her finger, then licking her lips. I sat there exhausted and motionless, waiting for Julie's response; she had a huge smile on her face. "Hmm... tasty." She congratulated me on my display, before leaning over again and wiping the last globule of cum off her bustier Julie then returned for another helping, but instead of slipping her finger back into her mouth, she offered it to me. I opened my mouth and let her finger enter before sucking it clean. "Lovely!" I declared with a big grin on my face. We sat and talked for what seemed like an age before I undressed and returned her underwear. I asked whether this would go any further, but she assured me that she wouldn't breathe a word, and with that I left her room. Once in my room I sat and pondered just what I had done...
