This upskirt happened 20 years ago but is still something I think about when wanking.

So I was 18 and my sister in law would have been 28. We are in the UK and she was classic private school girl, from the south, very well spoken etc. she had been going out with my bro a few years and always worn very demure clothing- very rarely wore skirts or tops that would show cleavage etc. you could tell she had an amazing body though and very pretty face. About 5 foot 8 with long legs and porcelain skin.

I was back that summer from university and ended up staying with them for a bit. As the weather got warmer she did start to wear some skirts that showed a bit of leg. Nothing too short but short enough for me to catch a glimpse of thing when she sat down and crossed legs etc. Nothing close to an upskirt though.

However that all changed a little later that summer. She was putting stuff up in the loft and asked me to help. She had a loose fitting skirt that went a little above the knee. She also had a white top on that wasn’t quite long enough to cover the back and as we were getting boxes sorted etc I could see a pink thong at the back of her skirt peeking up. That alone would have been enough for me to wank over as the thought of her wearing thongs was exciting enough.

However as we started putting things up in the attic I realised what was going to happen. They were the type of metal stairs you have to pull down to access the attic and she said she would stand on the stairs and put things up as I passed them. As she climbed higher up the stairs I could see a full view up her skirt as it fanned out a little. This revealed her small pink thong and a full view of her arse and also a clear view from the front of her crotch area. This was repeated as she went up and down the stairs and I got so hard. Once we finished I went to the bathroom and wanked which took about 30 seconds to cum.

I always wondered a couple of things about this

1) She must have known I would be able to see up her skirt.
2) I was going through some personal stuff at the time and wondered if this was her way of taking pity
3) was it a way to try to seduce me- her and my bro always argued and in some way would ha e been her revenge.


They are still together- I have had the odd upskirt glimpse of her over the years but nothing like that summer and whilst I’ve seen up many skirts since nothing has compared!
