Turn them into a second tier of slaves

As you looked upon the slaves whom had risked their lives to further your power, you started to realise how dedicated they were, and slowly began to appreciate the work they put in for you. It was time for a reward.

“Mera, you’re no longer the Queen of Atlantis, you’ll simply be joining the rest of your kind. I have a plan for them” you say with a smirk, stroking Mera’s head slowly as you thought.

"Yes my Master, your wish is our command" whimpered Mera submissively. Her eyes wide with devotion to you, as were all your slaves in the room.

"From hence forth the people of Atlantis will be giving their knowledge on magic and technology to the respective Mistresses, the knowledge of Atlantis will be used to serve my empire. As for the people themselves, they will become a symbol of my affection for the slaves whom distinguish themselves. They will serve as a **** to a one whom I choose to reward for their service" you explain.

"Of course Master, who do you believe is deserving of such a reward" she asks dutifully.

"Everyone part of this invasion is entitled to one such ****, as is my Order of Concubines. My inner council however shall be rewarded with as many as they wish for their exceptional service" you order, it wasn't as if you couldn't fuck the Atlantians anyway. Your slaves would always be glad to give anything up to you.

"You are too kind Master" answered Proudwhore "may I have the Queen?"

"Of couse, she's yours, go wild" you answered with a smirk.

"Your wish is my command Mistress" answered Mera crawling to Proudwhore's side.

"Hmm, you could be a bit better let's see... reggib stit" she muttered causing Mera's tits to balloon to twice their size "can't wait to show you to the rest of the magic order"
