One really naughty experience I had was when I was a college student. I had skived off my lectures one summer's day due to a hangover. By lunchtime I was feeling much better, but tired (and when I'm tired I usually get horny too). In the end I decided to lie on the lawn behind the house for some sun on my legs. I had the house to myself so I was thinking of going topless too, but I didn't get chance to go that far...
I had pulled my beige skirt up to the very top of my thighs, catching as much sun as I could, then pulled the straps of my top over my shoulders – maximum exposure. The heat was beating down without mercy and the hot air was making me a bit horny. I was led on a blanket, on my front, and my crotch was against a summer-hardened mound on the lawn. I remember I rocked my hips slightly against it through the skirt and the thick woollen blanket. It felt so good I started to really get into it. I opened my legs a little and shifted ever so slightly so my clit was getting a good rub against the hard mound of earth beneath me
I had subconsciously let my right hand venture down the front of my skirt and I used my fingers to press against the clit as I rocked. I decided to get out of my knickers so that I had more room for manoeuvre, kicking them away behind me on the grass. I squeezed and rubbed my clit underneath me in the blazing sun, my face buried in the blanket. It felt so good, before I knew it I was up on my knees, legs teased apart. If anyone had been in the garden next door and looked over the fence they would have seen my curvy rear in full view, with a set of fingers rubbing between my legs. Then there was a noise distracting me. It was the doorbell.
I remembered the landlord said he would be round for the rent some time before tonight. Shit, never mind I'll finish off after he's gone. I ran on tip-toes through the hall, opened the door. "Read your electricity meter love?" came the greeting. "Um, yeah..." I turned and let him in, knowing this wouldn't take long. I led him back to the cupboard under the stairs where the meter was - as I opened the door to the cupboard, I remembered all the crap that had been shoved under there for last week's party and realised I'd have to move most of it for him to see the meter.
I was bent over double, reaching in to move various bags from in front of the meter, which was fine – I wasn't averse to gratuitous flirting in those days. The guy behind seemed to make a noise, like a gasp, which was nice, so I tried to move the junk further into the cupboard, bending over further, honestly forgetting about my lack of underwear, forgetting about the length of my skirt. I suddenly realised how far in the air my arse was and paused before reversing out of the cupboard. The meter-reader had a visible hard-on. I was horny. Suddenly he seemed cute. He wasn't old or obese, he had a cock and I was hot. Simple.
I went into the dining room to breath deeply. Being on show like that and getting that kind of obvious reaction had made me even hotter. I pulled down the skirt and sorted my top out. He walked in: "That's all sorted." I thought impulsively. "Erm... while you're here... can you look at this and tell me what you think." I bent over again, this time into the corner of the dining room where the plug sockets where, and slowly cleared a space around the sockets while putting myself on show once more. "The one on the right doesn't work you see... can you just give an idea what it might cost to fix?" I was pointing my rear towards him, legs apart, stood on toes, thighs tensed. "Um, yeah, sure," he said. "Sorry, what's your name?" I asked as I pushed myself up. "Will," he replied.
