First, you recall from the book that, judging by the size and, now you notice, color of the hearts that she'll be under your sway for several days... if commanded she could carry out normally like she does until given a new command, or you could have her literally only do what you told her...
As for the spell... you are able to do it, and it's quite amusing. One of the choir girls is nearly passed out on the floor of a super market, one hand up her dress and is pumping her fingers in and out... she as no hearts but her eyes are certainly glazed over and she is thus unaware of the scene she is causing.
The other girl is at home, and had been in the middle of a shower... now she was groping her breasts and moanign like a whore as hot water cascaded down on her.
