Elwyn knows how to avoid people if she knows that they're tracking her, so don't expect to easily take her by surprise. On the other hand, she can be quite willing to be tied by those she likes or by those who will pay her enough of a commission, so bring a full wallet. She doesn't hide the fact that her chest is both the nicest part of her to view and touch, but don't discount the rest of her either, so be sure to bind her in ways to offer nice views of as much of her as possible. The same goes for giving her a gag since it's hard to decide between her eyes, hair and even ears. Double team squeezing her chest with stroking her ear to get the best reaction.
