This story happened almost fifteen years ago, but it still makes me unbelievably horny when I think about it. I have used the memory to make me cum ever since.
When my daughter was a baby, I would sometimes have a fifteen year old girl from the neighborhood babysit while I ran errands during the day or went to work out. One hot, sunny summer day Megan was babysitting for me and I was supposed to meet a friend for lunch after the gym, but she called and left a message for me that she couldn't make it. I thought about going out shopping, but money was a little bit tight for us at that time and decided that if I went home instead, I would save money on babysitting as well.
I pulled my car into the garage and entered the house. It was very quiet and I called out to say hello. No response. so I went upstairs to the baby's room where I found her fast asleep. I checked her in the crib and as I turned to walk away, I glanced out of the window and there below me, lying on a chaise on the patio was Megan sunbathing. Her headphones were over her ears, her bikini top pushed up over her tiny breasts and her bottoms hanging from one ankle. Her eyes were closed and her hand was in-between her legs playing with her downy pussy.
I should have been angry. If my daughter had woken, she would not have heard her, but looking at that teenaged girl caught me unawares and I felt an instant tingling in my own crotch. Without thinking, I lifted my short summer skirt and put my hand in my panties and rubbed my sudden wetness as I watched her.
I had masturbated a few times with a friend when I was in high school and this brought back the memories of those innocent times. Megan was lost in pleasuring herself and I mirrored her movements as I stood and rubbed my clit. When her hips began to really thrust up and down and she started writhing I knew that she was close to orgasm and I rubbed myself even faster and harder trying to cum with her. Unfortunately, it has never been easy for me to orgasm standing up and so I watched her have an intense orgasm and then quickly pull her swimsuit back in place and come back into the house.
She was obviously coming to check up on the baby because she started to come uspstairs right away. Quickly, I kicked my discarded panties under a dresser, smoothed my skirt out and stepped into the hallway. 'Oh, there you are,' I said. 'I came home and couldn't find you. Where were you?'
She told me that she had been sunbathing out on the patio and checking on the baby every few minutes. I don't know if she ever had any idea that she had been watched, but I got her out of there as quickly as I could, lay naked on my bed gave myself a huge orgasm as I closed my eyes and reran the movie of Megan over and over again in my head.
A few years later, Megan got married and my daughter was her flower girl. That night, I told my husband the story for the first time ever and he obviously liked it because he fucked me harder and longer than he had done for a long time.
I came twice while I wrote this. It thrills me to think that someone else may masturbate to my story.
