Jerk that dick until it is damaged and ruined.
The less you feel the happier I'll be. If you can't feel it you can't cum and then you are out of the gene pool. No breeding for you.
Your little damaged black-purple dick will never cum again.
Anything on your cock.. a chastity device would be a coffin for your dick.
I instruct you on how to go about desensitising your cock and preferring masturbation over sex then eventually unable to even enjoy and feel your own hand. Jerk it until you break it.
