Master really enjoys cumpolishing his Slaves cockhead but not well until he is edged up and his head has been polished until every swirly hand motion on his head makes him twitch and moan, and he begging for release. Master also throws in a little punishing ball torment during his slaves edging session to remind him it is not all fun and games for him but only for Master. After 15 denials he gets Masters wish and get that cum polished all over his super sensitive head. Sometimes it is a reward and sometimes it is punishment. It's all in the eyes of the Master.
