Harmony loves to cum. She loves it even more when she can torture a slaves balls while she is being licked! Straddling the slaves face, she takes her rightful pleasure from his tongue, smacking his balls hard totally at random in the process. Her moans of pleasure are such a delight to hear, interrupted only by the muffled screams of the slave when his balls take a hit. 'Lick it!' she demands when she detects a slowdown in pleasure, and the slave redoubles his efforts. He knows he will not escape ball pain today, but he still tries his best to orally please his owner. After all, you don't want to get on Harmony's bad side!
