You're My son, who despite being a fully grown adult, I still treat like My little babyboy. It's the night before Christmas and I'm reading you a bedtime story. I notice that you're moving your hand up and down under the blanket and I rip it off you, only to find you masturbating under there! I tell you that this masturbation needs to stop. That if you aren't able to control your jerking habits, that I will have to lock your willy away! I secure a chastity cage on you, whilst My huge cleavage is dangling in your face. I notice you staring and start telling you about your long time obsession with your Mummy's breasts and how long you were breast fed for, humiliating you until I eventually give you a kiss goodnight!
