Replying...
Intro. You wake up one morning with your girlfriend sitting next to you, angry, and a metal chastity cage on your cock. She found your captioned porn and is upset to discover that you wank to other girls behind her back. She's doubly upset that some of the captions are things you didn't want to try with her in bed. She's wants to slowly make you less appealing to other women, and to become the only person who ever touches your penis, as she feels it is hers, and you've been cheating on her by masturbating behind her back.
