In this lesbian BDSM masterpiece by Bound Heat, a strapon-clad slave is put to the test, ordered to bring her mistress to orgasm. The submissive, her body bound and gagged, is forced to watch as her mistress teasingly fingers herself, her pussy glistening with desire. The slave, her strapon throbbing, begins to thrust against her mistress's wet slit, the intense friction bringing the dominant woman to the brink. With a final, hard grind, the slave sends her mistress over the edge, her orgasm explosive and satisfying.
