Great story - Katrina's is Derek's student but has wanted him for years. That old student teacher relationship thing. The problem is Derek's got the whole ethical dilema and refuses to rise to the bait. So what's a girl to do? A masquerade party provides the golden opportunity for Kat to get together with Derek but she's not sure about the BDSM part - she's willing to explore but doesn't really know how far she will go.
