She did not resist, instead her thighs parted slightly to allow my hand to press between them as she encouraged me.
Pushing my hand up her skirt and under her knickers and tights, I found that she was pretty wet. But not simply through arousal. She was clearly having an issue holding herself in and had pee'd a little. I could smell her on my fingers. Anyway, I slid a finger into her slit and started to move it back and forth. Her legs parted further and I remember how large her lips were. They were quite loose and fleshy. And her clit was pretty large.
Her head had fallen to one side and she had parted her legs further for me as my hand worked on her slit. Rubbing it as I heard her moaning and encouraging me more. I remember her telling me how badly she needed this and had imagined something like this happening for some time.
She was becoming quite frenzied then and actually pushed her tights down around her knees. I recall looking at her standing there. Her tights stretched around her knees, pussy exposed as I rubbed her hard. I thought I would give her it even harder and forced two fingers into her cunt, lifting her suddenly to her toes. She gasped at this but hissed at me to do it harder. I pounded into her with some force and was a little worried about whether I would hurt her, but not this woman. She loved it.
As her breathing got harder and faster, I put more effort into fucking her cunt with my fingers. As she came, she clutched my head hard against her chest and pulled down the top of her sweater. Exposing a tit to make me bite her nipple. At this she shuddered really hard and ground her cunt into my hand. Soaking me in what was more than a little moisture. The drink was clearly affecting her bladder control.
Anyway, after that, I left the room and her and we never said anything more about it. She did look very sheepish for a few weeks afterwards.
