First, I would pin her arms down between my fingers on the hand she would currently be in. Then taste her all over, spend a little time sucking on her breasts, then fit as much of my tongue inside of her crotch as possible.
Then, when she has been tongue-fucked beyond the capacity for rational thought, I would start pleasing myself with the hand she was in. Feeling her mindlessly lick and kiss at my massive manhood as she is pressed into it hard, and smeared up and down it. The noises she would make would be rather cute as I go faster and faster.
And after I finish, I would check her over to make sure I didn’t hurt her accidentally, then give her a little kiss, thank her for doing such a good job, and let her recover in a nice tea bath.
