'Wait, ask for permission? When the fuck have I ever needed permission to gift a slave the honour of taking my cock? It's a warning, a warning that I'll cum and damn that was one satisfying load... I should make him pray for my cock again, that was so hot!'

In the end, Hertha confirmed her new sex slave was surprisingly sturdy. He might be weak but not only was he tough, but he was also flexible and could stretch to fit any cock and any position she wanted.

She got over-excited and accidentally pulled August's shoulder out of its socket by contorting his arm back but his shoulders seemed like rubber and snapped back in place when she let go. Even his oesophagus had no problem when she rammed her curved cock into it when inserted halfway down his throat, his cartilage was just as flexible as his joints; it was to the point she could clearly see her cockhead pushing up.

He was by far the best slave she had ever seen, the part that really got her going was that he was clearly enjoying it. She never was a fan of slaves because they were usually people who resigned themselves. It was only in certain situations they would be happy to serve someone, whether it was loyalty, love, awe or something else.

But August just loved to be fucked and even better, he just got tighter the more she abused him, a sex slave this talented and proactive was a first for her. Let's not forget that with her status and ability, she had some of the best out there.

Sex slaves were a Special class that could also have some combat ability so it wasn't looked down on as one might imagine. A sex slave was considered a display of status, wealth, connections and strength. They were hard to find and just as difficult to keep since so many people want them.

There were some hidden reasons for that too but the point was, she had already decided to make him her 'pet slave'.

A 'pet slave' was a slave that followed its master around just like a real pet, each master has a unique collar and leash that has their symbol on it for a 'pet slave'. In a way, a 'pet slave' was sort of like a fuckable secretary that dealt with all sorts of minor things. They weren't important but they were the face of their master.

Unbeknownst to August, who was currently panting in a daze with cum sloshing in his rectum with each breath, he had already been promoted to a position with a decent amount of power that many slaves would consider the peak of their life.

Oddly, despite Hertha having ownership over him, their relationship was similar to allies or sex friends with affection for each other. Neither commented on it, not even her aunt, but Hertha was surprisingly okay with it despite her sadistic and dominant nature.

"Your first task if you want to be my cocksleeve is to take my full-powered thrusts. All of your growth should be for increasing your toughness and toughness only, what kind of cocksleeve needs its owner to be careful when using it? You're flexible enough so even a sharp rise in toughness won't make your movements too stiff. Got it, slut?"

"Yes, *Burp*. Yes, mistress!" The full and satisfied look on his pretty little face with throat juices and leftover cum on his chin was making her balls throb.

'Control yourself Hertha, we need to get back soon to deal with those treacherous bastards first. I can always use him afterwards.' She quickly put her clothes back on and send out a unique magic wave. 

This was a special signal to call her khal-kaan, they were very sensitive to mana waves and attributes so each person who owned a khal-kaan would design their own signal, kind of like how fingerprints were never the same.

Soon enough the strange, muscular horse with antlers arrived from deeper in the woods, August was surprised since he expected it to appear from the sky's again but it also made sense that it didn't fly all the time. August tried to stand but his knees were still weak and he had so much semen inside that he couldn't stand.

"I'm going to need a little help here..." A groan escaped his lips when he sat up, he almost fell back down but propped himself with his elbows, he used one hand to massage his aching balls; he let out so much semen and even squirted out clear liquid in the end so his testicles were starting to ache badly.

Breina laughed a little and picked him up in a princess carry, he was so small it was both easier and harder than she thought. She was sure that a tenth of his weight was actually just the cum in him which was why he was heavier than she expected but still very light. "I've cleared the camp so let's depart. I've also made sure to get all of your things ready, this should go back in it's place♥!"

August squeaked tiredly when the plug was yet again inserted into his plump butt, "I can't believe I felt something was missing and now I don't... I'm adapting to this way too quickly."

The sadistic mistress chuckled as she mounted her magical steed, her refreshed look was even more ravishing than before, "It's all part of the job, slut."
