I saw her standing at the bar waiting on a drink. She was wearing a short plaid skirt and a tight white shirt that showed a green lace bra underneath. She was leaning over the bar just enough that the I could see the bottom of her shapely ass and the beginnings of what appeared to be a green thong underneath although I couldn't tell.
She swung her head around and beckoned me to come over and join her, so I made my way through the crowded bar towards her.
When I managed to get close to her though the only place I could stand was right behind her at the bar. Although this wasn't the ideal position for conversation I did manage to stop the crowd from bumping into her.
I bent over to ask her if I could buy her a drink when I got pushed forward by the large crowd. As I went forward my cock pressed against her ass and I could feel a little pressure as she pushed back into me. When I reached forward for my drink she whispered "did you like that?" sensually in my ear while at the same time running her and over the crotch of my jeans.
I responded by pressing my now hard cock against her ass again.
As the night wore on the bar got more crowded and I was getting pushed into her tight ass every few seconds. I was hard as a rock at this point and she kept pushing back into me and grinding against me when it happened.
I decided to get my own back on her because she was driving me crazy, so the next time she pushed her ass back I let my hand drop to her pussy. To my delight her thong was soaked so I started rubbing her pussy through it. I could hear her letting out little gasps and moans as I rubbed her wet pussy and she pushed her ass against my cock.
At this stage I was being driven mad by her grinding so I leaned forward and whispered "Are you drunk enough to let me in?"
Her response was to unzip my jeans and grab my cock.
