"Well, sounds to me like you're having a little crush on mistress Stella."
"No mistress, of course not!"
"Based on the way you're talking about her.. Are you sure?"
"Yes mistress.. My only crush is right infront of me mistress"
"Aww..aren't you a sweetheart?. Stroke faster now, show me something. Grab your balls with your other hand. You know I like it when you do that"
(You do as she says)
"You mentioned that mistress Stella made you hold an edge. For how long excatly did you manage to do so slave??"
"A..a..about 3 minutes maybe mistress..fuck"
"That long?. You wouldn't lie to me, would you?
"N..n..no mistress"
"Very interesting slave.. Go on, stroke it even more intensely and you may also use the other hand again.. Tight long strokes up and down your whole shaft"
(You follow her orders)
"Ok then. let's talk about the elephant in the room here slave.. So if you'd be so kind to answer my next question.. How long did you hold your edge for ME during our last session?. I can't remember darling.. Could you refresh my memory real quick?"
(You lower you head.. hoping that Tess would drop the issue.)
