You've been out with your friend to Karen's flat to collect some things she thought you might like to use on your new possession! You arrive in good spirits laughing with your friend (talking aside as before) saying "this is great! I can't wait to see his face!" You arrive wearing an overcoat that covers everything and black stiletto boots.
The coat is to increase the shock factor, because you open it to reveal a sexy satin look corset that pushes your breasts up (I'm thinking red, blue or purple) and the shock is because it's what Karen used to like wearing for his punishment sessions!
You love the dread and look of fear in his eyes and say to friend " OMG he's actually quivering!" He has backed into the corner on his knees but you shout to him " come here! I didnt tell you to kneel, come right up close, so I can put this on you" then you produce a collar from the bag and do it up tight, then use a hand mirror so he can see what he looks like " look at yourself boy! See what you are now? You'll wear this constantly to remind you of your place, I'll send pictures to my friends too, you'll only not wear it in public" Then you attach a leash and laugh as you tug him about left and right up and down, accompanied with face slaps, then pull him up really close, perhaps blowing smoke in his face if you fancy a cigarette and say "do you remember I said things were going to get worse for you? This is just the start, you have no idea what I and my friends have in store for you! Now open that mouth - wider! ashtray!"
You could say asides to your friend things like "the girls are going to love this" and "I must ring Karen and thank her - I had no idea how much this was going to turn me on!
