In a cramped bathroom, a feisty sister, bored with her cousin's visit, decides to spice things up. She strips and teases him, her curvy body glistening with sweat. Her cousin, initially hesitant, can't resist her advances. She straddles him, impaling herself on his throbbing cock, her tight pussy gripping him greedily. They fuck hard and fast, her big ass slapping against his thighs, their moans echoing in the small space. Just as they're about to climax, they hear someone approaching, forcing them to quickly clean up and act innocent.
