A thick, veiny cock, glistening with lube, presses against a tightly puckered virgin hole. The friend, skilled and patient, grips the virgin's hips, applying steady pressure until the head of his cock pops inside. The virgin gasps, her body tensing as she adjusts to the initial intrusion. Her friend pauses, allowing her to acclimate before slowly inching deeper, filling her virgin ass completely. The virgin's moans grow louder, her body squirming as she experiences the intense pleasure and slight discomfort of her first anal penetration.
