Sylphiel is a gal of many magical talents, but most people don't know that, so trying to take her off guard will prove that she knows black magic and she knows it well. Fortunately, it's much easier to get her to agree to be tied willingly as she's often too nice to turn the invitation down. Her regular outfit draws attention to her legs, but they hide her best features: her chest and hips, so feel free to CCR her into something that allows for easier access to both. Almost any kind of gag works well for her, but it's best to stick with ones tied under her hair to allow it to flow freely when she moves. She doesn't mind her squeezable spots being touched, so long as things don't go too far.
