Since moving out of the area, S had started to behave really outlandishly, she was also begining to show off, she was blonde, slim and if I say so myself, rather good looking, the trouble that led to the latest event occured one afternoon when she'd decided to visit the local shop, run by an older guy who was a bit of a pervert! Now it happened that also living in our street was a girl, a little older than S, not as attractive or well dressed, but with a fairly large pair of tits that she was not averse to using to her own advantage. She would regularly walk around in tight blouses with a couple of buttons undone giving a good view of her ample assets, one day much to the annoyance of S, who'd been queing in the local shop, this girl had walked in wearing a see-thru black blouse and a black bra beneath, the old perve had served her straight away so as to get a good look at her tits, S went mental! Over the next week or so she began to pay increasing visits to the shop, always wearing tight tops, often without a bra and always wearing really tight leggings or jodhpurs, quite often without panties, I knew she was up to something. One day I returned home from work and she said she had been shopping and bought some new leggings, well they looked like riding jodhpurs, beige and extremely tight, but also very thin a bit like those running tights that women wear today. She said she'd put them on so I could have a look and then went upstairs, not long after I heard her coming downstairs and she shouted to ask if I fancied a beer, I said I did so she said we'd walk to the local shop, when she entered the room she had done her make-up and was wearing the leggings and also her thighboots, I couldn't tell what top she had on as she was wearing her jacket. We walked down to the shop and she got several wolf whistles and admiring glances from several young lads that we passed, as we got to the shop doorway, S suddenly did a very strange thing, "here hold this" she said, taking off her jacket, god I nearly died on the spot! Beneath the jacket she was wearing a see-thru black chifon blouse, and nothing else, no bra, nothing, her pert 34B's proudly displayed for all the world to see! "lets see how he likes this" she giggled as she walked into the shop, the old perv noticed her instantly and went to serve her straight away despite other people already waiting, I've never seen anyone take so long to get a 4 pack of beer and some cigarettes, clearly the old perv liked what he saw. She never wore the top without a bra outside after that, but she did sometimes wear it to the shop beneath her jacket, just to keep him guessing, she was turning into one really sexy exhibitionist, and she was about to get kinky with it.
