I have quite a few fantasies but there are a couple that are really strong in my mind that I'm hoping to try...

1: Tie the woman down to a bed and pleasure her orally for hours without letting her go all the way, driving her mad with desire, making her beg for me to finish her off, until finally I take her all the way and the orgasm(s) she gets blacks her out.

2: Make the woman wear some of those underwear that vibrate, with me controlling the remote to them. That way I could turn her on whenever I wanted, but not letting her have an orgasm for a while until when she does have one, it's really obvious....(maybe in public, don't care or not)
