In the small town of Camao, Heloisa, a married novinha, finds herself alone with her thoughts and desires. She slips into her bedroom, her heart pounding. She strips naked, her body glistening with sweat, and begins to touch herself. Her fingers dance over her clit, then delve into her tight, wet pussy. She's lost in the moment, her moans filling the room, when she hears a noise. Her husband is home, watching her from the doorway, his eyes filled with surprise and lust.
