Fran, haunted by religious guilt, struggles against her carnal urges. Carlos, her stepbrother, remains a temptation she can't resist. She tentatively reaches out, her fingers brushing against his hardness. Carlos gasps, his cock twitching in response. Fran, her resolve crumbling, takes him into her mouth, her tongue swirling around his sensitive tip. Carlos, his hands tangling in her hair, guides her, his hips bucking gently, as they both inch closer to the edge of their taboo pleasure.
