He didn't figure out how to escape

Gallarth squirmed for hours until it got dark but it was useless all she managed to do was hurt her ankles and wrists, by the time Concha came back with the slaver she was planing to seel her previous master too, she was still laying there in the basement, tired from her useless struggle and crying and sobbing pitifully in despair as he was about to lose everything including his freedom.

"Alright, let's see what we have here" the slaver commented as he picked up the goblin bitch like nothing so he could check her out, the slaver was a human man with an obese body, terrible theeth and only one eye, his second one had apparently been cut and he cover the eyehole with a patch and a nasty scar that cover half his face, he moved her all around as he lifted her so he could observe every detail of her so he could measure her value, he didn't left any degree of privacy even looking into the inside of her pussy, Gallarth felt disgusted at the treatment but he didn't fight back, he knew he would just end up hurt if he did "She seems to be healthy, no scars or other unpleasant marks on her greenskin and surprisingly she's even a virgin, you got a great catch here miss Concha, well at least for a goblin, even a decent goblin **** like this one usually doesn't sell by much, I could give you 5 copper coins for her" the low price hurt his pride even more than the molestation that was the body inspection, his life now was considered not worth more than a few pieces of copper, it couldn't even be silver."

"Sure I can accept that, I honestly just want to get rid of this green whore, I don't care if you don't pay me that much for her" Concha said heartlessly as she pull her arms forward to receive her payment, the slaver took the coins from a pouch on his pants and right before he was about to give them to Miss Concha, he suddenly pulled away.

"You know now that I think about it, what's stopping me from tying you up and taking you both as slaves for free" he said making a creepy sinister smile.

Concha didn't consider this possibility and was now backing off a couple steps in fear "You wouldn't dare, unlike green bitches like the one I'm selling my kind has rights, you can't enslave me unless I'm a criminal or if I conceded my liberty" she tried to point out, what she was saying was legally true but there were slavers that didn't care about the legality of how they practice their work.
