Being useful

there’s so many different dynamic styles and roles that appeal to me as a sub (ex: punching bag, pet, jester, advisor, sex toy, servant) but above all I love feeling useful to women and I can’t remember a time where I wasn’t preoccupied with this goal, to the point where I have learned specific skills in order to be more useful. It just comes natural to me and it makes me happy. Now that I know this about myself, I can’t wait to be able to explore it in a more healthy way! I think what I’m most excited about is being a form of stress relief. subs, what’s your favorite way to be useful? Dommes, what’s your favorite way to use your sub?
