You're just about to start fucking her when you notice that she's still got her bra on. Time to use that to your advantage, gripping on it and using it for leverage to fuck her that little bit harder.
In quite the show of strength and dominance, you not only manage to sweep her off her feet, but also hold her upside-down in a standing 69. This gives you freedom between her legs while she has to choose between working between yours or trying to escape.
