When their parents leave on a trip, adult childhood-friend role-play partner Mia suddenly begins spending every day at the narrator's house. She catches him staring at her exposed panties and orders him to lick her pussy, beginning ten straight days of cunnilingus. She sits on his face the moment he wakes and demands service until bedtime—during meals, in the bath, and even after using the toilet. She recruits his acquaintances for a contest to find the best pussy eater, then climaxes wildly across ten scenarios until her pubic hair is soaked with pussy juice, saliva, and constant oral attention.
