They proved to be beyond stubborn

Rayla gave herself a push and a spin. Pirouetting through the air, she brought down her right foot like an axe to the side of poor Fyn's head.
She felt the hit connect. It was a vicious blow, bone against bone, it should have knocked the boy out for good, yet he was barely staggered by it.
Before she could register the unexpected, Rayla felt her ankle being grabbed.

She looked down, suspended between the chain and Fynn who had blocked her leg on his shoulder and was overcome by a rush of adrenaline.
If she didn't move, the others would be on her in seconds and she would have been done for.
She hit Fynn with her left foot, she did it multiple times. On his chin, on his chest, she discharged a flurry of blows which soon turned the face of the farmboy in a puddle of blood and tears.

Yet he didn't let off the hold.
Noticing that Edrig was closing in from her side and that Tilor had got up from the ground, Rayla panicked, not the kind of panic that freezes you in place rather that kind that makes you struggle because your life depends on it.
Putting all her strength in another **** blow, she steeled her feet and jabbed the tip of her toes right under Fynn's chin. He gave a throaty yelp and staggered back with his eyes out, holding his neck.

Edrig tried to catch her as she swung back. Rayla felt his hands, his fingers, graze the right side of her hipbone.
Working against her momentum, she bent her legs as much as she could, doubling herself up, then brought them down to the sides and using the spin of the chain uncoiling itself, she kicked away the smith's apprentice with a quick one-two that left him with a sore red bruise on his cheek.

The last one to launch himself on her was Tilor. Rayla made quick work of him crushing his head between her feet and pushing him away. But despite the double hit to his temples, that still wasn't enough to put him out as well.

For what felt like hours - Rayla quickly lost track of time - the three Human prisoners continued to mindlessly throw themselves at her.
Sometimes they did it simultaneously, more often they went one by one in random order. There was no strategy behind their ****. Despite this, they kept trying and trying.

Rayla just reacted, she had no time to think because they needed no time to rest. All that she could think of was that their stamina appeared to be endless. She swung and twirled around like an ethereal, butt-naked puppet on strings, her kick flying in all directions, barely breaking a sweat through all this.

"Hey guys, it's not that I'm complaining, uff, uff, this is actually good leg training but, don't your faces hurt?" wheezed Rayla at some point.
The three Humans stared at her blankly through the slits of their swollen eyes. Edrig and Tilor noses were broken and bleeding. A couple of their teeth were on the ground, hard to tell who they belonged to at this point.
"Pussy," they moaned like a mantra.

Rayla winced uncomfortably. She had tried to go easy on them at first, just with jabs and pushes to keep them at bay, but hit after hit, she had started to get into the flow of battle and the damages has started to pile up and show.
Now the three Humans' faces were a sore, bloody mess. They had also more than a few bruises on their bodies, especially the torso, but the faces, those were really a mess.

Rayla felt bad, she kind of wondered if she had disfigured them forever. Those were three good, honest Human faces after all, even if a little dumb-looking.
But which of those was not, after all?
At this point though, there was no turning back, for how much pity she could feel for them.
They had turned into mindless, sex-crazed, drones, and she didn't want to think what they could do to her if they laid their hands on her.

The problem was, she had gone too soft on them when she could hit harder, now she was beginning to feel the fatigue. Her whole skin had grown of an intense shade of pink and was covered by a thin layer of perspiration. There were a few bruises on her legs, and her feet were starting to ache. It was only the adrenaline that was keeping her up.
It was really hard to tell if the guys were getting tired too either. Their bodies looked strained, but their minds didn't seem capable of acknowledging it.

Poor sods, the potion was pushing them beyond their limits.
The situation was dire, Rayla knew she had to end this now. She had to go for the kill if she wanted to get out of this.
