ok so I  got a hard on at work after I was cleaning under a table  an a female colleague sat on my back an blamed it on the chair being moved.we giggled about it, but all i could think was "will you order me about." I was so excited I went to the toilet and masturbated.

so as punishment i took my punishment swimsuit, it's a onepiece swimsuit age 10-13, and i have glued pins in the crotch, buttocks and breast area (there are pics of it in my profile).

I then went for a ride on my mountain bike for about an hour. it was very painful, and i could barley sit down for longer than a few seconds at a time. every time i peddled it rubbed them against my whole crotch area, balls and against my rock hard cock. 

 I deem this a suitable punishment , but if you have any other ideas pleases inform me.
