She opens her mouth

She smiles up at you, "You've never tasted Queen's shit before, have you?" she says and hungrily licks it from your shaft.

She pauses before licking the underside of your cock, "Not one of my turds is ever wasted." she says and adds a culinary tip for your benefit, "It's especially tasty with mango chutney on toast, I think, but good by itself too."

She then enthusiastically licks the underside of your cock, shitty brown stuff collecting at the corners of her mouth.

"Here, try," she says, scooping some on her finger and offering it to you.
