Sra. Orgastica, a devout woman, is tested when Carlos, her step-son, reveals his desire for her. He pulls out his massive, throbbing cock, and she's mesmerized by its size. She can't resist, and soon, she's on her knees, taking it deep into her throat. Their passion escalates, and they fuck wildly, his big cock stretching her tight pussy. As they grind, their wetness mixes, and he pounds her harder, revealing the truth of their forbidden lust, like the cobra's dance during the São João celebrations.
