Rope, kind of

You pull at the tabs on the top and the box opens easily. At first you think it's just filled with an ordinary red woven rope. And then you nearly jump out of your skin as it moves. Sure you've just opened a package full of snakes you retreat and ask Cerve to investigate. She walks up to the box, laying motionless on the floor.

Cerve : "It's just smart rope honey, it's harmless. Well, mostly harmless."

She picks up a length of it that immediately starts coiling around her forearm like a vine in search of sunlight. Cerve looks at it and then looks at you with a predatory smirk.

Cerve : "This might be more fun than I initially thought sweety."

You gulp as she approaches you. Half of you is scared and the other half is turned on by the idea. Your clitty is filling up your spacious cage.. You had given up control and left yourself in the mercy of the SFC folks in a way already but this would make the matter even more explicit.

Your inner turmoil robs you of any meager chance you had to resist. Cerve closes the gap swiftly and gives the rope a quick wrap around your torso and then lets it do the rest. You struggle at first, there is something very primal and impossible to rationalize about something that moves distressingly like a snake coiling itself around you. You knew that this wouldn't hurt you, but your monkey brain knew that the monkeys that let the snake constrict them didn't survive to pass their genes on to the next generation. It ultimately didn't matter either way. Once it had a grip on you with it's advanced synthetic muscles the game was already over. Your arms were quickly bound behind your back and bits broke off to bind your feet to your thighs.

You continued to strain at the rope for a few more moments before settling down. Cerve helped position you in a way that you realized was to give the SFC "team" access to your caged crotch. Now that you had calmed down you find the position surprisingly comfortable and the helplessness of it was a real turn on. Anyone could come in and do whatever they wanted with you.
