You have to accept two things: 1) Your Mistress is just a needy restroom slut eager to please her superiors. 2) You're just her pathetic cuck, who can't stop dreaming about seeing her uncensored body. π½
I put her in chastity because sheβs being too slutty. Would you like to have her key and control when she gets fucked? Or leave her locked and just use her mouth?
