Jealousy simmers in the air as the younger sibling watches his elder sister entertaining another man. His eyes, green with envy, feast on her body, imagining her moans for him. As the man leaves, he seizes the opportunity, cornering her in the hallway. Her eyes, blue with desire, meet his, and she can't help but feel the bulge in his jeans. Their lips clash, teeth clanking, as they give in to their forbidden craving. His hands roam her body, cupping her generous breasts, while hers tug at his zipper, eager to release his yearning cock.
