I'm of a masochistic nature and recognise the elation of serving as slave rather than sub, but sub would suffice. I have no issue what so ever about unconditional submission and becoming the property of a superior Mistress / Master and devote myself freely into life of servitude; for domestic, social and sexual service for their self gratification and desire and unfettered pleasure. I have few hard limits. With all that said Switching is not an issue and can become a 'mean' Master!
Desires and Fantasies
Oh, several interesting desires regardless of the role!
