Secret Fantasies

I'm a software engineer by day, but at night, I indulge in this secret Daddy fantasy with my submissive partner... It's been going on for a few months now, hidden from everyone... We have these elaborate play sessions... She calls me Daddy and listens to me... I discipline her when she misbehaves... it feels so intimate and powerful... yet shameful too... what if someone found out?... we're careful though... still, I worry about the secrecy...
