8 XXX : Bondage

Nice! This is one of my Mistress's go-to ties, but we often don't do the knots so closely spaced, I bet it's more comfortable and also more strict the way you've got it. ?
my question is how long do you want to have sex with that on you? real question.
Really pretty!
Question: What are the sleeve-binder things called that hold a lady's arms in position called? Google can't direct me to something based on a description so I have to ask here.
