My sexy sub doing as told and making sure to ask permission

Yep.

Oh!

May I come, sir?

I didn't hear you.

May I come, sir?

A little bit louder.

May I come, sir?

Yes, you may.

Say it, I can't hear you.

One more time, louder.

Yes you may.

Keep going, that's how you start.

Whoa, I can't hear you.

May I come in?

Yes you may.

Oh, thank you sir.

Good?
