Kate takes it slow, wanting him to enjoy the feeling of her soft nipple encompassing his legs as much as she did. She lowers her hand very slowly, her nipple inching up Marcellus's body until just his head remains outside. She places a finger on the top of his head. "Have fun in there, dear!" she tells him, then thrusts him deep inside. She pulls her finger back out with a pop, and sucks the milk off of it. Inside her breast the flesh is incredibly soft and pillowy, and there is a shallow pool of milk in the centre.
