Trapped together during a rainstorm, stepsiblings Michelle and Lucas find themselves drawn to each other's bodies. Michelle's eyes linger on Lucas's growing bulge as she touches herself, her fingers dancing over her clit. Lucas, unable to resist, joins her, his hand stroking his thick cock. They argue, but the tension only builds. Finally, Michelle can't take it anymore. She straddles Lucas, impaling herself on his massive cock, riding him until they both come undone.
