When little cupcake loses a dare and is made to spend the night in the Haunted Nursery, she's a little afraid...but she's more afraid of being teased by her friends if she refuses! She tries to doze but sometime during the night... the Cummy Monster strikes! It pulls down her blanket. It unsnaps her onesie, revealing her thick pink diapers. And then... it possess little Cupcake, making her body the host for out of this world orgasms! She can't control her body and is just a puppet as she's made to hump and ride the magic vibrator until she makes cummies in her diaper! She pleads with the monster, what if her friends hear? What if she gets in trouble for making a grown up mess?? But the Cummy Monster doesn't care. Cupcake cums again and again, another victim of the Haunted Nursery's need for bad little girls!
