Gag Talk and Restraints

Display thoughts and emotions. Emphasis how this affects you as a character. Go through fears and aspirations. Physical moves that your body can perform can help as well to create a good response to the actions of your oppressor. As for voice you usually mumble and moan and blink and cry and have wide eyes rather than speak of course

Exactly!
(The wide eyes you mentioned are some real good details)
When the story and action is just going on and moving forward details are harder to describe, but when you're stuck in such positions, your posts can be more about giving the picture more resolution.
Your surroundings, the weather and temperature, the feeling of whatever those restrains are against your skin and body and the way they limit you and how your emotions react to those limitations and physical traumas, your facial expressions and e.t.c

Like if I'm to be tied and gagged
I like my partner to use a Whitehead mouth gag (damn they're hot) they stretch the mouth all wide open to the very limit and give you this sweet little hard pain on the jaw and you'd most likely not be able to gulp

Whatever the position is, if you're tied all secured and tighr, the ropes will burn your skin a little and the longer you're locked the more they hurt against your muscles with your body stretched in a position your joints mist likely don't used to

I’m curious. How do you handle your character if they are restrained? Like if your opponent ties you up?

Also how do you handle being gagged? I like the idea of being gagged but I don’t have much experience writing gag talk.
