Tsk Tsk, apparentlly no one ever told you what the word "slow" meant. What am I gonna do with you stroker boy. Can't even follow a simple order I see.
Take the head of your cock and slap it hard against the pal of your head 10 times. Let that be a reminder, punishments only get harder.
Now repeat after me, "I will never fuck up again mistress, I promise to stroke and ache for you!."
