A stern mistress takes a bisexual sub under her wing, determined to teach them the art of pleasuring any cock. With a dominant hand, she grips the sub's chin, forcing them to look up at her, then at the two erect penises before them. "You'll please them both," she commands, pushing the sub's head towards the first cock. The sub hesitates, but the mistress' firm hand on their head guides them, encouraging them to take the throbbing member into their mouth. The sub struggles at first, but the mistress' patient tutelage has them bobbing enthusiastically between the two cocks, learning to take them deep and pleasure them both.
