Sabrina, the alluring blonde prima, can't help but feel a thrill of the forbidden as she masturbates in her room, her fingers sliding in and out of her wet, untouched pussy. Her cousin, drawn by her moans, enters and finds her in the throes of pleasure. Instead of leaving, he joins her, his massive cock straining against his clothes. Sabrina, her heart pounding, takes him in her mouth, savoring his size before she straddles him, impaling herself on his length. They fuck frantically, their taboo lust consuming them, until a noise outside her room brings them back to reality, leaving them breathless and guilty, but yearning for more.
