When you are, well and properly, restrained, no movement will be possible. In my fantasy, not only will your wrists and ankles be secured, but your hips and shoulders and head will, too, so it won’t simply be that you can’t escape. You won’t be able to thrash, buck, or even writhe. Your entire body will be still, like it or not.
I need to go shopping.
I see ropes and cuffs in your shopping cart 😉
With ideas like in your head, you can have hours of fun wondering round a hardware store. Its even better if they’re with you to ‘”try things on”.
