No, he keeps his composure

"Thirty. Thank you, Master," croaked out 5088 as his body shuddered involuntary from the throbbing pain that emanated from his backside.

He'd done it.

Impressed but not all that surprised that 5088 held on against your rough spanking, you felt emboldened to push it further next time.

There was bound to be a point where slaves would crack, wasn't there?

Although there was much to be considered and experimented with, you've delayed yourself enough and decided that it was time for both of you to get your just rewards.

You slowly and softly run your palms against 5088's backside much to his discomfort.

"You've done great, boy," you praised him as you continued to play with his tender flesh, "I'm very proud of what you've done today so I think it's time for you to get your reward."

Not wasting any time, you grabbed the head of the butt plug and pulled it out of 5088 unceremoniously, revealing his gaping hole. Without warning and additional preparation, you lined up your length against his open hole and plunged in, forcibly burrowing yourself inside him in one stroke. Focused on just getting yourself off, you took very little time to savor the incredible tightness of what you knew to be a well-fucked hole. Instead, you used him like a fuck sleeve and just went at it, grabbing his hips and thrusting in and out of him as hard and as fast as you could.

Feeling the tell-tale signs of your upcoming orgasm, you slowed down your thrusts and started to spank his backside again, forcing him to tighten around you. Unable to resist the warmth and vibrations, you finally let yourself go and filled him with your second batch of seed today.

By instinct, you reached down to jerk him off and were reminded of his situation when you felt cold hard plastic where his cock was supposed to be. You laughed to yourself. He was a ****. You didn't need to care about his pleasure.

Still slightly hard, you continued to fuck his well-abused hole, milking as much as you could from the pleasurable feelings of your highly sensitized dick. Eventually, you softened enough to plop out of his anal cavity.
