What would be your favorite way of being tied up (or tying her up)? With what are you using? (rope, zip ties, etc)
Same goes for the gags: any favorites? Just your hand?
My preference is paralysing her with fear and using any brutality necessary to tame any notions of fighting back. But I love a fighter. Some of that is a small fetish for masochism, as I can enjoy being hurt, but it's also no small amount of sadism as I want to manhandle and intimidate her.
My first rape of her will be all about isolating and controlling her, but as I decide to enjoy her again (and again) I may resort to a rape kit containing something to restrain her so my hands can be free to explore, though her own clothing may suffice in a pinch. Zip ties and handcuffs are quick and dirty, so more utilitarian than preference. Rope is more personal and artful, but I've got to either frighten her into letting me bind her, or knock her senseless enough that I'll have time to secure the ropes. Duct tape is somewhere in between.
As for a gag, wadding her panties into her mouth and securing that with duct tape or a more secure gag is always fun, though a bit dodgy if you don't want her accidentally suffocating. My preference is to have my bare hand over her mouth, so I can feel the vibrations of her screams (and possibly the pain of her bite).
One of the more creative 'restraints' I've encountered via resident puppygirl Ingenue is a muzzle for a gag, puppy gloves which prevent her from using her hands, and ankle-thigh restraints that prevent her from fully extending her legs. You ladies may not be into pet play, but you must admit that the particular restraint system can leave you VERY vulnerable - and perhaps wet!
