Lately, the mistress finds the slave really annoying. She's not really in the mood to play with him, but still generous enough to give him a handjob. She massages his tiny dick with her experienced, gloved hands. The slave gets aroused in an instant, but his happiness doesn't last long.
The mistress lets go of his member right at the moment when he's about to come. The mistress then laughs at the unsatisfied slave, leaving him behind with the words 'maybe next time'.
