Before taking your faggot sex slave remember to insist on trying out the merchandise first.
First and foremost, test to see how much, if any, of a gag-reflex the slave has. Face fuck it as deep and hard as possible.
Does it seem to like on being used like a hole and having your Cum flood its throat? If so, that’s a good sign.
Then pound it’s cunt mercilessly, Bareback. Does it submit without protest, questions, or resistance? If so, that’s another good sign.
Finally, order it on its knees, piss on it and down it’s throat. Does it quickly obey, immediately open it’s mouth, and obediently swallow all of your piss? If so, this is another good sign.
You can now be pretty confident that you have a worthy slave. One that knows it’s place and duty to serve you, its Master, completely.
