Just let her continue?

Miley continues to sing the song. She's singing it slowly, with a slightly different tune, drawing out the scene. She leans back and looks you in the eyes as she strokes your cock and sings for you. She smiles slightly and then leans far back, arching her back so her titties are sticking straight up into the air.

She sits up again and begins to rub your cock against her crotch, over her panties. You look down and can see that her panties are wet; partly from sweat, but also partly from her excitement.
