giving you a good spanking...
There's only one thing for it - you're going to have to be punished.
I've given you every chance to behave, and yet still you insist on behaving like a dirty little girl, masturbating in here secretly, thinking I won't see you, thinking I won't know what you've been doing.
Such a little slut.
My little slut.
And you do know what a dirty little slut you are, don't you...?
I think it's time you admitted it.
Not that it'll save you from a spanking, of course. You still deserve to be punished.
But if you're prepared to admit to me what a dirty little slut you are, and if you bend over and take your spanking like a good girl, then I'll reward you afterwards. I'll slip my fingers deep inside you, and tease you, softly. If you're really good, if you tell me what a slut you are, and beg me to fuck you... then perhaps I'll allow you to touch me... maybe even let you take me into your mouth... we'll see ;)
If, however, you insist on being a brat, then you'll be spanked, hard. The particularly bratty ones amongst you will be tied up first, then spanked, and then made to stand in the corner and watch, as I deal with the other girls.
It's up to you.
Are you going to be a good girl?
Then pull down your panties and bend over the couch...
Spread your thighs for me, I want to see you...
Admit to me what a slut you really are...
