You're all locked up and I've got the key on my necklace, I know my big tits make your little pecker so hard, and in that cage it hurts so bad when you get an erection and I love seeing you in agony as I tease you and taunt you with my big tits in your face. Teasing you with the key, it's so poetic to me, watching you ache for me as I tease you with the key to your cockcage sitting daintily above my fantastic cleavage. I have the key to your freedom casually situated on my chest, you want out my little cucky chastity slave? Give me $100 and I'll give it some consideration. $200 would make me give it more consideration, $300 would make me very seriously consider letting you out and letting you stroke till you cum... maybe.
