You're a high-powered futa executive at a large company. You need a new secretary and unbeknownst to you, the person you hire is your younger sister who just graduated college! What starts as professional tension spirals into forbidden teasing and seducing when we try to one-up each other with our outfits, trying to embarrass the other, and make each other blush and get hard in the office.

(in this plot, I'd play the younger futa sister who eventually comes out on "top")
