I have a remote vibrator and remote electric play unit. One day during work - I work from home - I attached both at the direction of my Dom. He would occasionally turn one or both on to mess with me. It was so hot to try and keep focus while being edged and shocked all day.
That's hot! It's funny to think what it'd look like in an office environment. Those around you keep hearing temporary vibrating sounds and you showing/trying to conceal pain/pleasure. In my head it'd be pretty evident pretty quickly, but I guess that'd depend on the kinkiness of one's coworkers :P
