Mistress milking her slave to collect a huge load of cum

Yes.

Stand up straight.

Don't slouch.

Now let's see how this feels under your undercarriage.

Let's see if I can follow the line up here.

Cracked.

Stand up straight, what did I tell you before?

You are not allowed to come without my permission, do you understand?

Yes.

Maybe I should get a little lube.

You didn't answer me properly before.

Yes, Mistress.

That's better.

I got this little specimen cup to milk you into.

I'll just put that there.

Once again, before you come you have to ask permission, do you understand?

Yes, Mistress.

I feel like I'm milking a cow.

Oh God.

Whew.

That's quite a bit of a specimen.
