In my office with my hand.

I once saw a brilliant game played with two lesbian women. Here it is: You strip the slave naked (or even better, make her strip naked herself, and gag her so she can't speak. Bend her over a table, or something fairly low, and tie one leg up by the side of her. This basically exposes all of the anus, the butt-cheeks, and some of the vagina. When she is tied up and helpless, you can fuck her - with a dildo or your real cock if you are male. Alternatively, you can fist her. The real aim of the first part of this game is to get your slave to be screaming with pleasure. Hear them moaning their little socks off as you fuck them senseless. The next part of the game relates more to the question: still naked, tie her up with her hands above her. Put spreader bars between her feet as well, so she has absolutely nothing to protect her ass and pussy. Then tell her that she has two options - one is a vibrating dildo, the other is a whip. Tell her that if she cums, she will get punished. So what you do is this: plunge the dildo into her vagina and watch her wriggle about for ages until she is practically forced to cum. Then get the whip, and flog whatever part of the body you like - ass, clit, midriff (a personal favourite) or tits. You can repeat this until your slve apologises for being disobedient or offers to lick your ass clean. You can make up your own rules... Note: this should only be done between consenting partners, not maliciously. I would like feedback on this please. Thanks

if I were a guy I'd imagine on my dick her pussy best place to flog..
