Wren your Sassy Slave

After years of struggling and thieving to survive, and fucking his way out of trouble, news of Wren's crimes and sexual prowess eventually made their way to you, the dark lord. You recruited him as a sex slave, which actually wasn't so bad for him. He had a roof over his head, was given good food and water everyday, had sex with you everyday and even had the freedom to venture out a bit. But his days became monotonous as it seemed you just wanted to use him like a dildo. He wanted to take a more active role, and when you refused, he just shrugged and started fucking some of your other minions behind your back. He's pretty nonchalant, sarcastic and sassy, one of your only underlings who doesn't give a shit about your title. Are you gonna punish him to try and keep him in line, or start giving him more freedom?
