When I was visiting relatives I used to roam around my Uncle & Aunt's house with my cousins playing hide & seek and other games. Once, when I was waiting to be found, I saw a catalogue in my Aunt's bedroom - I can't remember it's exact name but it had a large clothing section. I leafed through it, gawping at the lingerie section for a while, but then my eye caught the fitness clothing they had. There were a couple of pages full of women wearing the most amazing clothes I've ever seen. They looked like one piece swimsuits, but they had thong bottoms and the models wore them over tights. I was transfixed and when my cousin found me I quickly had to shut the catalogue and hide my erection which had mysteriously appeared!
I went back to that catalogue whenever I could and stared intently at the models wearing those super-tight thong leotards and tights. I loved the way the fabric clinged to every contour of their bodies. The high cut of the legs and the thong bottom turned me on especially. I also noticed how some of the leotards had high necks as well, which I admired nearly as much as how the thin material of the leotard disappeared between the models' ass cheeks! Sometimes I glanced back to the lingerie section of the catalogue and noticed that some of the outfits were similar to leotards. These bodies were more lacy and, instead of being worn over tights, they had suspenders attached to stockings.
Playing a later game of hide and seek I went and hid in my cousins room. I noticed that one of her clothes drawers was open so I had a quick look inside. To my surprise and intense delight I found a couple of one piece swimsuits. I picked each one up and felt the smooth fabric run through my fingers. I could see how the cut of each swimsuit was very similar to the leotards in the catalogue (sadly apart from the thong bottom and high neck). By sheer luck I heard my cousin giggling outside the door, so I just about had time to put the swimsuits back before she entered the room (although I couldn't move for a few minutes as I had to wait for my erection to go down!).
Once I had found those swimsuits then my curiousity grew and grew. We visited my Aunt & Uncle about once every other month. Every time we visited them, I suggested playing Hide & Seek and immediately went off to hide in my cousin's room. During those games I searched through all of her wardrobe and drawers. I found several pairs of leggings and, best of all, a drawer full of tights.
One afternoon, my family all decided to head out to the shops but I insisted on staying behind (making up some excuse about watching TV, even though nothing was on at all). Once I heard the car leave the drive I ran up to my cousin's room and grabbed her swimsuits and some tights. Just to be on the safe side I went to the bathroom and locked myself in. I rushed to strip my clothes off and then stood, completely naked, looking at the swimsuits and tights arranged on the floor. I had never worn tights before, so I spent a while looking at them, trying to work out which leg was which! I picked up a pair of white tights and began to put them on, one foot at a time.
My cousin was three years younger than me, so all her clothes were a bit too small for me. Luckily the lycra in them meant they stretched well and I was just about able to put her tights on! Once I had both feet in the tights, I began to pull them up my legs. I felt how snug the fabric was around my legs as I brought them up until eventually I pulled the waistband over my ass. I then realised why girls were always tugging at their legs - the tights weren't entirely comfortable just yet! I pulled the fabric higher and higher, working from my feet upwards until there were no loose bits and the waistband was high across my stomach. I also found that I had to point my erect penis directly upwards and let the tights press it flat against my belly!
Once I had the tights on, I selected a light blue swimsuit. It was a sporty style one, with high cut legs and the straps crossed over at the back. I put my feet through the leg holes and pulled the suit up to my ass. It was very tight and I could feel the pressure as it squeezed my cock and ass. I pulled the body of the suit up higher and put my arms through the straps. Again, the suit needed some pulling in different places so that it felt right, but then my dress-up was complete! It felt better than I had ever imagined: my legs looking and feeling slender and smooth, my body felt amazing too underneath the swimsuit.
There was a mirror in the bathroom, but it was small and I couldn't really check myself out in it properly! I sat still for a minute or two until I was sure that I couldn't hear anyone (although I knew everyone had left a while ago). I unlocked the bathroom door and ventured out into the hallway. At this point I realised that the windows were all open and the neighbours could easily look in and see me wearing my cousin's tights and swimsuit! The urge to see myself properly was overwhelming and I took my chances with the open windows and went into my Aunt and Uncle's bedroom where they had a large mirror. I was then able to see myself wearing tight lycra for the first time! I must've spent ages posing before that mirror: standing up, checking out the bulge in my crotch and then my tight ass and then kneeling on all fours on my Aunt & Uncle's bed, checking out my ass again.
I realised that time was flying by, so I withdrew back to the bathroom and reluctantly stripped off the swimsuit and tights. I was shocked to find that my cock had started dribbling cum and there was a small wet patch on both the tights and the swimsuit! I heard a car pull up onto the driveway so I had no time to do anything about it - I quickly put my clothes back on and put my cousin's amazing lycra back in her room, hoping that no one would ever spot the small cum stains!
From then on I was hooked and spent all of my time working out how I could wear tight lycra as often as I could!
