Just leave her behind like this

You reach over, avoid getting your fingers bit, and pull the gag back in her mouth. Sayza protests, and starts making angry incredulous noises.

"Thanks for your cooperation."

You grab one of her boobs and pinch it, then turn on your heel and walk away, followed by a smattering of muffled cursing, some of which you manage to identify as 'son of a bitch', 'bastard' and something that starts with 'fucking...'. You ignore it, only glancing once over your shoulder to see Sayza wriggle furiously against the wall trying to get up, until she loses her balance and keels over unto the ground. As you leave you watch her lying there, a topless girl in her panties with her pants down her ankles, squirming on the ground, until she passes out of sight behind the corner.

You wonder if she'll get free on her own or whether someone will have the good fortune of coming across her like a little wrapped present, but that's not your concern.
