Let's watch it throb and twitch for a bit. It's so cute, pet. It really does have a mind of it's own. Look at it, just begging you to finish the job.
Too bad it doesn't know that I am it's owner and it will only cum on my say so. Those are the rules, aren't they slave?
We're going to watch it twitch and bob in defiance for five whole minutes. During that time, it is going to keep HARD for it's owner, and keep bobbing. You will squeeze your PC muscle every few seconds to make it bob for my amusement, toy.
