I was eighteen and in high school when it happened, my brother was twenty and still living at home. I had to borrow my brother's computer one day to do some work for school and I guess maybe I let my curiosity get the better of me a little as I found myself instead of writing the essay I was supposed to be working on, looking through what files he had saved on his computer. I was pretty interested in particular by a very full folder hidden away in a place that you would not expect to find it. Now, I'd been a teenage boy for long enough to know that I had probably just stumbled across my brother's stash of porn saved from online. Now, it's perfectly natural in such a situation to check out what's available, when there's an opportunity to look at porn it's not common for an eighteen year old guy to turn down that opportunity. And besides, I was finding myself slightly curious about just what my brother was into. We had never been that close, he was big, sporty and laddish and I was small and introverted, and didn't really share things like other brothers might so I really didn't know, did he prefer blondes or brunettes? Curvy or skinny girls? I really couldn't tell you.
Whatever I might have assumed about my brother's tastes, I could not have expected what greeted me when I started opening the files in that folder. Because what I found was a huge number of picture and movie files showing beautiful women of all kinds, white and black, fair haired and dark, busty and flat chested, but all sharing one very obvious feature, a very unfeminine cock between their legs. Yes, it turns out my brother had a little bit of a thing for girls that were a little more than they seemed. Well, more than a little bit of a thing, he was completely obsessed. There were images of gorgeous, convincing, feminine crossdressers and shemales posing in sexy lingerie, getting their cocks out and stroking them and then more hardcore stuff, shemales sucking off guys or being sucked off, getting fucked and fucking. It was an amazing collection and it showed that this wasn't a passing fancy for Darren, this was something he had invested a lot of his time in exploring, I wondered which were his favourites and how many times he had sat there in front of his computer wanking himself to these images.
After my initial reaction of shock and surprise, I didn't know quite what to think about this discovery about my macho brother. It seemed so weird and disturbing to get a window into the kinky things that turned him on and it was certainly something that I had never really thought about too much before, these men who could pass successfully as hot and sexy women yet beneath their skirts still held onto that one strong aspect of masculinity. Although it started out just seeming weird, I was finding I couldn't stop looking at this stuff, I kept opening the files, playing the videos, I was engrossed, completely fascinated by these strange but beautiful creatures. It began to be an incredible turn on for me watching a hot girl fucked hard in her tight arse while she stroked her own hard cock.
I was beginning to see what Darren saw in these shemales, they were something special and watching them I began to wonder what had made them want to become like women in the first place, what had attracted them to cladding their bodies in those soft and sexy clothes and acting like dirty sluts, giving it up to anyone who wanted it. By now, what had seemed weird and unnatural was starting to sound exciting and alluring and I realised I wasn't just fantasising about these beautiful heshe girls on the screen but fantasising about what it would be like to be like them, to be a hot slut chick with a dick dressed in sexy lace lingerie.
I knew I had to find out and I knew just how, after all there was someone very close to me who I was pretty sure shared some of my new fantasies and could probably be persuaded to explore them with me. I wondered whether Darren had ever been with a real tranny girl before, I mean he was pretty popular and especially with the girls, he was tall, muscular and handsome, but I couldn't imagine where he would meet a girl who could show him just what he wanted and anyway he had a reputation to keep up, he couldn't let people know just the kind of women he really would go for or that reputation would be ruined. I kind of hoped he hadn't lived out his internet fantasy in real life, it would make it a lot easier for me to seduce him. Yes, that was my plan, to give my brother a taste of what he longed for and get to fuck a girl who wasn't quite all woman and to let me try out a bit more of my feminine side, I decided to seduce him. I knew it was going to be tough, even though he lusted after transvestite and transsexual girls would he be able to get over his macho exterior and actually let himself fuck one? And not only that but I was his brother and that would be a pretty big hurdle to get over for anyone. Still, I was pretty confident that as long as I could transform myself into a sexy and convincing enough woman then he couldn't help but give in to his lustful side and given an effective enough transformation then I could almost become like a separate person, I hoped he would stop seeing me as his geeky younger brother and instead just fall head over heels in lust with the sexy Cynthia, that was the girly name I had picked for the person I was to become.
Well, it wasn't long before I got my chance, although it seemed an age with almost every waking minute cementing my desire to transform myself into a naughty girly slut making me unable to concentrate on anything but my fantasies. One evening, my parents were gone away for the weekend, leaving just me and Darren in the house. Darren had gone to a friend's house where they would probably drink beer and watch TV. Hopefully, when he got back a little drunk his inhibitions would be loosened up and he'd be more receptive to Cynthia.
With the house to myself, I ran a bath to get myself totally clean and shaved off all my body hair with my mother's leg razor, giving me silky smooth legs. Already I was starting to feel more feminine and loved the feel of running my hands up the soft smoothness of my hairless legs. I dried myself off and sprayed a little of my mother's perfume on to give me an alluringly sexy, womanly scent. Then it was time to raid my mum's closet for suitable seduction outfits.
Fortunately, my mum had been a pretty attractive woman in her day and remained so even now, I guess she's where I got my slight frame and long legs from, so she still had a pretty sexy wardrobe. I decided to keep it fairly simple so went for a dark suede knee length skirt and a white blouse with short puffy sleeves that was so thin it was basically see through. Now for the exciting part, the underwear. My mum had something of a treasure trove of sexy lingerie and I ended up opting for a pair of lacy bikini cut briefs and a matching bra. Stuffing the bra with tissues gave me what approximated my mum's C-cup and then sliding the panties up my newly smooth legs was something of an erotic feeling. In the underwear I felt totally girly and the soft feel of the lace on my cock and arse was delightful. I slid the skirt up my thighs and zipped it up, being taller than my mother it came to a little above my knees and showed off an impressive amount of my long bare legs (I hoped Darren was a leg man as mine were definitely my best feature as Cynthia, something that would be the envy of many real girls).
I was pleased to note on doing up the blouse that the outline and colour of my naughty red bra was clearly visible through the thin fabric but as I was using tonight to try and get off with a macho lad I decided to reveal a little more, leaving a couple of buttons undone so the scarlet lace around where my cleavage would be was well visible. I topped the outfit off with sexy shoes, red with four inch heels that were at first difficult to walk in but, after a little practice, gaving me a sexy sway to my walk and did not end of good to the curve of my calves and the sight of my pert little arse in the suede skirt.
All I needed now was hair and make up, I thanked my luck that I had recently been growing my brown hair long and it didn't take too much time with my mother's styling products to make some gorgeously feminine waves that fell over my shoulders and instantly made my face look more womanly. A little make up further enhanced that with blush to bring out my cheekbones, dark eyeshadow and scarlet lipstick the same colour as my bra and shoes. Looking in the mirror, I could tell that I would do pretty well. I had never considered quite how good a girl I would make even when planning this but the clothes, hair and make up completely transformed me. I was Cynthia, long legged beauty with the kind of slutty make up job that a guy like my brother was sure to go for. Now, all I had to do was wait.
After a drink to calm my nerves, I sat on the sofa and waited for my brother to return, all sorts of thoughts running through my head. If he doesn't go for it then what will he tell mum and dad? If he does then I'll not only be getting fucked for the first time but by my own brother. I just hoped I was ready to handle that. Well, I guess there was nothing for it, nothing I could do now as I heard the front door opening and my brother's footstep stumbling a little on the threshold. As I heard the door slam behind him I steeled myself for whatever was to come and went out into the hallway to meet him.
"What the fuck?" said a visibly slightly drunk Darren as he watched a hot girl saunter towards him in a short skirt and heels, only realising it was me when I was right beside him.
"Welcome home, big boy," I said in my best husky feminine tones, reaching up and running my hand along his arm, caressing his impressive bicep.
"Steve, what are you doing? Why are you dressed like that?" he sounded more confused than angry.
"Tonight it's Cynthia," I said, still rubbing his arm but now leaning to whisper in his ear, "And tonight I'm all for you."
"Come on Steve, what's going on?" he said, pushing me away.
"I know what you want," I continued in Cynthia's sexy accent, licking my scarlet lips saucily just in front of him, "You want a girl like me and tonight you can have her."
