My step cousin lets me pull down her pants and she has no underwear

I went into a teens fashion shop and came across a nice skirt that gave me an idea. It’s definitely a summer skirt, short, porn very light, patterned cotton and very A-line. My thought was that it would be excellent to wear on a windy day and hopefully flash my bare butt and pussy to some people couple thus achieving another item from my list. I took it to the changing room and quickly took my clothes off. I put the skirt on and it felt like I just had a thin belt just above my hips. I did a twirl in front of the mirror and the material rose up and out so that even from where my head was, I could just see my slit in the mirror. People in front of me would get a great view. Changing back into my my own clothes I went and browsed until I found a top that was also very light, baggy, low cut and short with just spaghetti straps stopping it from falling down. Satisfied that it had potential, I took it to the changing room, stripped teen and put on the new skirt and the new top on. I pulled the top down as far as it would got and saw that I had about 15 centimetres of flesh showing. Doing another twirl I smiled at what I could see and noted that the amateur straps on the top were in real danger of slipping off my shoulders. I decided to to go out of the cubicle and look at myself in the mirror at the other end of the changing room to get a ‘distant’ look at myself. I did another twirl and was satisfied that anyone more than a couple of metres from me would get a great view if / when the skirt blew up. I was so busy looking at the skirt that I hadn’t realised that one of the straps of the top was down near my elbow and an older man with a young girl walking in gave me a funny look as he looked at my chest. I looked down Fucking and saw my exposed right tit. “Oops, sorry.” I said and quickly pulled the top back into its proper place. Back in the cubicle I took the new clothes off and looked at myself in the mirror. I liked what I saw and started dreaming about the skirt blowing up while I was out in public. Before I knew it, my right hand was rubbing my pussy. When I realised what I was doing I stopped, said “no, not here,” and got dressed. I was a happy girl as I went and paid for the items and left. "First, she's not my property, she's my friend," teen Morgan said, caressing his strong jaw. "More?" He pulls it out and amateur couple both of us falls on the bed. They all just looked so relaxed, shaking hands with other patrons, and waving to others. I followed him and watched as he unlocked a small door and opened it. "Ohhhhh Fuck . . Fucking . Vic’s face got red. Mom.. “They need to be porn sucked.” She hissed at them. Taking a quick bday shot with them all, we started to walk outside.
