A favorite fantasy of mine is the 'guilty Dom', a wife or a girlfriend who really loves me, but just can't keep herself from torturing me. In the fantasy, she tricks me or drugs me or otherwise gets me helpless, and spends hours teasing and tormenting me, apologizing for it and adding extra humiliations all at once, and I endure it out of love, and when it's over she's horribly guilty and very loving and kind and sweet, caring for the damage and promising never to do it again, but we both know sooner or later she'll give in to the desire again.
