In a cramped closet, a religious yet curious novinha and her brother explore their forbidden desires. She tentatively reaches out, tracing the outline of his cock through his pants before he springs it free. Her eyes widen at the size, but her curiosity wins out. She strokes and licks it, amazed at how it grows harder in her hands. He tells her to take it all, and she tries, gagging slightly as it hits the back of her throat. She pulls back, spitting and gasping, before taking it deep again, determined to make him cum. He does, grunting and filling her mouth with his load. She swallows it all, wiping her chin, and they both collapse, panting and guilty, yet satisfied.
