Certainly - like I said, just a bonus and makes for lots of easy plot points.
Speaking of, what sort of plot do you have in mind, Nymph? What sort of sub are you thinking?
Do either of you have any particular kinks/scenes/ideas you'd like to incorporate?
My interest lately has lain with scenes that are sexy, but not pure sex: taking the pet to the company social, for instance, and torturing her a bit while we smile at clients and act outwardly proper, or have her employed as our secretary, or have her serve a romantic dinner.
Naturally, those would likely proceed to more carnal bits of fun, which I don't want to avoid at all.
