Time for some hands on restraint training. In fact, more like hands off and strapped to a chair just like every other limb.

The best Mistresses know restraints in and out, literally. Emerald wanted to learn more about how to trap someone, and somehow we don't think she'll forget after an experience like this. Her job is to study the straps for how to best recreate it on her next helpless submissive. Looks like she's enjoying it too much to focus, which might just mean we have to keep tying her up.
