This True story happened when I was twenty. I was working as a handyman for a local builder and was sent to a borstal/home on the edge of our town to replace a broken mirror, I arrived and went to the office and was told to go to block D and ask for Carol and she would show me where it was
This I did and was shown by Carol, an attractive dark haired woman of about 35 ,to a utility room on the second floor, it had two toilet cubicles on the right and two large china sinks on the left hand wall Carol left saying she would be back soon as she had some washing to do ,I thought no more of it  put the new mirror on a small stool that was just a little bit in front of the sinks and got on with taking down the old mirror which was on the wall between the two toilet  doors  . It was about ten in the morning so all the borstal boys were at lesson's so we were the only ones in block D.

A short while later Carol came back in with another arm full of washing. I couldn’t believe my luck the mirror was still in the same place and Carol made a joke about me dragging the job out a bit

She then carried on with her washing  still splashing and chatting away, I tried to answer her as best as I could but was not really listening, as I tried to get into a good position again, this time when I looked down at the mirror  I nearly let out a long moan as when she has gone out she had taken off her knickers and I could now see  both her beautiful dark pussy lips, although they were covered with  dark curly hair they hang down and sort of parted back a little bit to show a lighter pink colour .
 My cock was out and rock hard in no time with me wanking it for all I was worth , Carol’s  legs were further apart now and she was really bending over the sink pounding on the washing but not talking , her ass was moving slightly from side to side as she did her washing, and I was right behind her, just as well she was splashing a lot as I’m sure she would of heard my juicy foreskin rapidly going back and forth,  I didn’t last long as I thought iwas about to cum I slowed down my wanking to enjoy the sight of her loverly round ass and pussy for a little longer but it was just to nice and  my cock shot its load across the room and onto the toilet door about two feet away it was all over the mirror on the stool  and a large white blob landed on Carols skirt .

I was quite cold in the untility room and as I looked down it looked like steam was coming from my still swollen helmet I quickly put my still solid cock back in my jeans cleared my throat and tried to get on with my work hoping she wouldn’t turn around and see all the cum everywhere . Soon Carol again said she had finished her washing and asked if I wanted a cup of tea I said yes , And without turning round she took her washing and went.

I quickly wiped up the cum that was running down the door and then cleaned the mirror. As I was washing the last of the cum from my hands in the sink I looked down at the mirror and realised that she must have been able to see every thing I had been doing as she lent over the sink, I  blushed bright red and finished putting the new mirror up as quick as I could ,just as I was about to creep out  Carol came back with my cup of tea. I again went bright red ,But she just turned round and started cleaning up the sink still chatting away,  The blob of cum that had landed on the back  her skirt had now soaked in and made a a dark damp  mark on her light grey skirt ,
I said my good byes left ,but as soon as I got home I had to have another wank, well I was only twenty.

I’ll Never know if she was watching me or not ,but if not why did she take off her knickers off .

Since then I’ve  had many  fantasies and wanks  about all the things I should have done  but was to scared to do at the time , To this day its still one of the sexiest things ive ever seen;. thanks Carole
