Edging my bound slave with oily latex gloves

Description: My slave has been a quiet and obedient boy while locked and bound in my basement. i decide to reward him for his obedience and persuade him to maintain good behavior by stroking his cock with my oiled latex gloves. i softly degrade him while his cock leaks more and more as i edge him. his fate is in my hands: will i ultimately gift him an orgasm, or will i deny him one to remind him of his place?
