Mistress performs medical exam and two hands fisting

Can I pet you sir?

Show me what you can do.

Good boy.

I should not be going. Who knows if the elbows are done for?

Yeah, I think we're really good at this thing.

Just one more finger.

Just the two fingers.

It's time for three fingers.

Maybe it's time for four fingers.

Yeah.

Open your mouth for me.

Good boy.

Yeah.

Oh dear, I bet that was large.

I don't know what I'm doing right now.

I'm putting two fists in your fucking mouth.

It's not painful.

It's not painful at all.

Such a cute **********.

I will stay here for a moment.

Why?

You can have two of my fists on your ass.

Maybe next time I should take another doctor and put three fists on your ass.

This is a good idea for you.

Tell me, is this a good idea to put three fists on your fucking ass?

Let me think about it.

It is a terrible idea.

You know why?

Because I have only good ideas.

And you must listen to me.

Let me talk something for you.

I'm not so gentle.

You know why?

Because you don't deserve to be gentle.

You don't deserve to be gentle at all.

You don't deserve for that.

I said, beg me.

Have mercy.

Good boy.
