Switched With My Secretary

Bodyswap, Gender Swap

Lucas Reed just got a big promotion and his future is looking bright. So why isn't he happy? It might have something to do with the fact that the project that got him the promotion was primarily done by a generous coworker named Martha who was passed over for the very same position. Martha is angry that yet another man has scrambled past her on the corporate ladder and she's ready to do something about it. With the help of a secret spell, Martha gets Lucas to switch bodies with his buxom and vivacious secretary, Zelda. Lucas is going to find out exactly what it's like to be a woman in the office, and just how far you have to go to get ahead.

Perfect little story

Has all the tropes you want. Glad there was an actual gender swap/body swap
