Sango isn't one to let herself be taken off guard easily, but she does like being tied by people she trusts, so take the time to get to know her. If she's in her combat outfit, bind her with a rope shibari and give her a gag that accents her lips. If she's in her casual outfit, bind her with tape or something that works well on loose clothes while using a gag that covers her mouth and draws focus to her hair. No matter what she's wearing, don't be afraid to enjoy squeezing her butt for a good long time as Miroku has already proven that it gets the best reaction from her.
