Tiuzao, the burly stepfather, finds himself the object of his stepdaughter Rosita's desires. In a cramped, dimly lit room, Rosita, the branquinha, wraps her lips around Tiuzao's tiuzao, hungry for his leitinho. She gags and struggles, but the tight seal of her lips and throat around his girth sends electric shocks of pleasure down Tiuzao's spine. As Rosita eagerly swallows every drop of his hot, creamy load, the taboo of their act only serves to heighten their pleasure.
