Yes, fighting back is definitely part of the thrill. At first you don't know how far the captor(s) would go - are they really bad-meaning people or just a bit drunk, you try to find the safe way out and all of a sudden (as this is a consented scenario) you rasie your voice, your arms fling out, but the other guy's already there and yank your arms hard behind your back, lashing them tight, and then he juts his elbow into your belly. You get groggy with sudden pain and sweat, and try to fight back but you're no match for the thugs any longer.
When you come to fully, your arms are roped tight to your back, your feet stretched to the bedposts, one of the men is past your cuntlips, your mouth is sealed with your tangas and some tape, and you know that whatever they want to get to know from you, first they'll use you as their slave girl for some time.
Great, but if I did a really hardcore scenario IRL (like, being suspended upside down, whipped and fucked by two men at once) I'd talk over the security side of it a bit. I know I'd feel hot though.
