In her mouth

"Open your mouth" you say. She lets go of your cock and opens wide. You shove your cock in, jerking off. This submissive milf licks your head, and finally you erupt. Her mouth is filled your your thick, sticky cum.

"Swallow."

She looks at you, hesitatingly. Then she commits, swallowing your cum.

"Good girl." you touch her with your hand, softly stroking the side of her face.

"J-just trying to help you out." she says, shyly.

"You're one submissive slut, aren't you?"

"Excuse me?" she says, feigning shock.

"Aren't you?"

"Yes."

"You probably would have swallowed my cum even if I didn't have a medical condition, wouldn't you?"

She looks away.

"I don't know your husband, but he's a cuck now. He'll have the privilege of paying for my treatment. You'll visit me whenever you can, and when I'm out you can be my fuck toy."

"I-" she is too stunned to speak.

"What's a matter, can't afford it?"

"No, I'll do it. To help you get better."

You smile.

"Good."

You look down on your cock, realizing that there is still some cum on it.

"Clean this" you say. You give her your cock. She begins cleaning the head, licking every part of it. Sucking the last drops of cum from it. Enjoying this pleasure, your cock begins to stiffen to attention once more.

"I'm sorry, John".

You sigh.

"I don't want to wait for the next nurse. How do you intend to fix this?"

"I'm sorry, I'll.."
