I work as an IT consultant and do a part time shift on a Saturday morning. It's very dull but the pay is good so all I have to do is sit in an office the size of a broom cupboard all alone and fix problems online when they occur. Usually I have been out the night before so I use the time to try and recover. More often than not I get extremely horny and surf the web usually checking out Solo Touch and rubbing myself off. The office overlooks a small back yard and the windows have that reflective stuff on them to keep out the sun so it's really private inside.
Sometimes during the morning a girl would go into the yard and hang out, her mum probably worked somewhere. I watched her sometimes to break the boredom, she was a pretty blonde girl and had a fine pair of breasts. This particular morning I was feeling very randy and had already brought myself to the brink of an orgasm when the girl arrived in the back yard. Being a fine day she had on a vest and a pair of very tight towelling shorts, as she strolled about I couldn't help but admire her figure and young firm breasts, her nipples already hard and pointy no doubt caused by the hormones surging about her body and I smiled as I remembered discovering my developing breasts a few years earlier and with that I felt the urge to slip a finger under my bra and tease my own nipples.
As I squeezed and tugged away I looked out of my window and watched the girl who sat astride the metal railings either side of some steps right out side my office. As I continued to watch her I became aware she was riding the hard metal pole gripped tightly between her thighs. The horny cow was grinding and rubbing her sweet little pussy right onto the bar, her cheeks were flushed and I almost came on the spot as I watched her rocking her tight little bum. I just had to dip my fingers into my wet slit and I rubbed for all I was worth watching this girl getting off no more than six feet away, suddenly she closed her eyes and locked her thighs tightly around the pole and jerked against it as she came, my own pussy twitched and gripped my fingers as I had a small orgasm. For a moment she just sat astride the pole then she lifted one leg over giving me a view of her crotch, with that she picked her panties out of her bum and strolled off leaving me with a strange but nice smile on my face.
