From a very young age I was fascinated by girl’s knickers, knowing that girls were different I longed to know what was inside their underwear. I loved getting a view up girl’s skirts even for the smallest glimpse of their knickers. As I grew older this fascination never went away, instead it became more of an obsession, I was always dropping my pencil in class to look up girl’s skirts, sitting in the playground watching them do handstands against the wall or watching them with skipping with ropes often gave me a good look at their knickers. The girls wore a large variety of colors, pastel shades, pink always being a popular color, my favorite ones to see were plain white cotton or the old-fashioned navy blue school knickers some girls still wore, I’d often have to conceal my erection in my pants from looking up a girl’s skirt, even seeing knickers on a washing line got me going, the underwear pages of my mum’s mail-order catalogue got some close scrutiny too.
When still at school my neighbors asked me to pop in and feed their cat while they went on holiday once, I agreed as they said they would pay me. The first day I fed the cat then decided to use the toilet, in the bathroom stood a laundry basket, my curiosity piqued I looked inside, to my delight the first item atop the pile was a pair of navy blue school knickers belonging to the daughter who was around the same age as me. We often played together and I had looked up her skirt on many occasions, I didn’t fancy her but she was not bad looking with nice long blond hair most often in tight plaits with bobbles at the ends. My hands trembled and my heart pounded as I picked her knickers out of the basket, lifting them to my face I inhaled the lovely scent left behind by her in the nylon school knickers, oh the first time I smelled a girl’s scent in her knickers, heady, musty with a tiny pee aroma. I got my cock was out and rubbed it on the gusset where her pussy had been, I came in no time careful not to get any spunk on the knickers, putting them back where I found them I felt happy but a bit ashamed about what I had just done, the shame quickly evaporated as I could not stop thinking about her lovely fragrant school knickers, I wanked in bed that night thinking about them.
Next day I fed the cat again then straight to the bathroom, the nylon knickers had felt so exciting rubbing my cock on them, I decided I would put them on this time, my first time ever putting on a pair of girl’s knickers, little did I realise where this would lead but that was not what was on my mind, I was imagining where these knickers had been as I slipped my feet into them and pulled them up over my stiff cock and smooth bum, I looked at my bum in them in the mirror, stroking it imagining it was hers, the front looked like a tent with my erect cock so stiff it ached, stretching the nylon material, they felt fantastic on, so sexy, I couldn’t stop myself cumming in them very quickly making a mess in the knickers, I quickly wiped them as best I could, returning them to the basket.
The next day was similar apart from trying her bra on too, the white cotton bra felt good on, her white school socks felt nice too as I pulled them up my calf, smoothing them and imagining it was her legs I was caressing, dare I go the full hog with her pleated navy blue skirt, white blouse and school tie? Of course I did, I loved it, pretending I was her in her lovely prim school uniform, oops I made a mess in her knickers again.
The following day I decided to look in her room, typically girly with lots of pink, ‘which draw contained her knickers’ was what was at the forefront of my mind, quickly located I felt like it was Christmas day, pastel colored ones, pink ones even some with Barbie on them, the age label on them was younger, ‘she must still like them too much to move on just yet’ I thought, then there was her school knickers, over a dozen pairs like the ones in the basket, she went to quite a strict school and I remember her telling me that they still had ‘knicker inspection’ and that girls were caned if they had on anything other than the regulation navy blue, I remember thinking ‘I want that job’ he he. She also told me that if caught with any other knickers on than the regulation ones the girl would be made to take them off and go knicker-less all day, I wasn’t sure wether to believe her or not but it sure got me horny, imagine the lucky teacher who got to keep the knickers! As I looked at the large number of school knickers I thought to myself ‘surely she won’t miss one pair?’ I took a clean pair and swapped them with the ones from the laundry basket, pocketing them for myself.
That night in bed I spent sniffing them, wearing them and imagining I was her in them, I must have cum loads of times.
Back in her bedroom the Barbie knickers were soon covering my cock, they were a tight fit but this just made my dick feel so good in them, her pink nightie also felt good on as I lay on her bed hugging her pillows with her smell on them, I even played with her Barbie dolls, their faces got wet with pre-cum.
By the end of the week there was hardly nothing of hers that I hadn’t tried on, dresses, skirts, tights and every pair of knickers she had, the first time I put her tights on was fantastic, I was amazed how the nylon stretched, feeling clingy on my skin, my legs felt lovely to stroke, I had never much liked tights but this experience changed my view on them, I couldn’t wait to stroke a girl’s legs in them now.
When I saw her next it would be so erotic knowing that my cock had been inside the knickers she’d had on.
No one ever knew what I got up to, I hid the school knickers away, wearing them as often as I could, I even wore them out to the park on occasions, wanking in the woods or the toilets in the park.
Over the years my love affair with knickers has never waned, I ‘acquired’ several more pairs and in my late teens I hardly wore underpants any more.
My collection numbers over 200 now, I still have the first pair I wore, several more school ones too, I love them.

Anyone want to hear about how I got into dressing and my first dressing experience?
