 I'm so happy to hear that. I was hoping that when you came back home you'd be in the mood for some naughty fun... *slips out of my lingerie to reveal my ready body* What do you say?
 well then, maybe it's time for me to make it even greater. *smiles seductively* I've been thinking of some naughty things I could do to you...anything in particular you'd like me to do?
