Wait after school and sally ( warning)

You decided sally would be the best bet, her family is basically your family. And you've always been attracted to your cousin. You walk home with her talking about school and such. Trying to hide your excitement. Once your there. You guys play some games and hangout till it gets late. Luckily her brothers are out of the house and her parents start work late. "I think you should head home or spend the night here" you decide to say you'll head home. "Alright love you!" You head out of her room and hide in the house. After half an hour. You hear the shower turn on. Perfect! It would be best to use the fog in a similar environment right? You barge into the bathroom scaring sally to ****. "HOLLY HELL, WHOS THERE" "oh, sorry sally. I needed to ask you something" you start to twist the jar "cant it wait till after im done?" you unscrew the lid and the fog slowly raises out of the jar. It seems to gravitate towards the heat. You place the flask on the rim of the bathtub. "So what was it you wanted to ask me?" You cant tell if its working or not. Or maybe it takes time. Better think fast though or she might think your trying to be a pervert
