office strip, to hotel dare - nude under coat
 

Send your partner a set of selfies throughout the day, in various states of undress.. May need to take several pics in one go, to avoid suspicion as to why you are nipping to the loos every few minutes!

Depending on where you sit, maybe even risk a boob peek / upskirt, while at your desk- make sure the camera flash is off!

If possible, get partner to book a hotel day room nearby, for a lunchtime frolic- strip off and go over wearing just a long coat, and shoes. If really daring, leave all other clothes at work!

Get room service arranged before you arrive, to avoid any disturbances. If the doors have peepholes, give him/her a flash, before being let in.
