Slave survived the prep session without cumming so now Master will allow Slave to be allowed to cum on drop at a time. But not until Slave is well edged and denied permission another 9 times beforehand. Slave does not obey very well as he does deliver one drop only twice but fails twice also. Master will not allow any of the cum to be waisted as it is very useful for cum eating obedience and behavioral reinforcement, and feeds slave every drop. Master punishes Slave at the end with Master's signature cockhead cum polishing after orgasm tormenting finish.
