Good- job

Scene 1:

(Lip opened and closed, head move back and forward.)

Sir: Do you like it?

Slave: Hmm... Yes...

(Tongue lick up and down.)

Sir: Tasty?

Slave: ...Yum...Yummy!

(Tongue tip turning round and round, lick from bottom to the top.)

Sir: How much do you love it?

Slave: ...so...so...so much.

(Ejaculate, mouth sucking loose and tight.)

Sir: Hmm.. good job. Why do you love it?

Slave: Because it's yours, my dear SIR.
