Rescia, João's adopted sister, has always been a temptation he couldn't resist. Today, she's pushed him to the brink. Wearing nothing but a thin, see-through nightgown, she struts around their shared room, her nipples hard, pussy wet. João, trying to study, can't ignore her. She climbs onto his lap, grinding against his bulge, her breath hot on his ear. "I know you want me, João," she purrs. He freezes, torn between desire and duty. But Rescia isn't taking 'no' for an answer. She unzips his pants, pulling out his enormous cock, and begins to suck him off, her hunger for his cum insatiable.
