She almost wants to sob, because she knows that this is too good, too much and that she's not going to get what she wants. It would be too easy to be allowed to cum, and Rose is anything but easy. She has to fight, even as her body tighten reflexively around tge vibe. Its obscene the noises Rose pulls from the moans the slick noise of her sister fucking her with it and its too easy to imagine its her sister's cock instead, fucking her so vigorously.

Rose pulls the vibe out and Dove can't help the soft whine of disappointment that escapes her. But she then drops and she knows what's next and how its going to ruin her even as her sister presses bruises into her flesh. And she's right, Rose's mouth hot and her tongue working her open even more, both better and worse than the vibe had been.
