Alina, the naughty stepsister, catches Rose masturbating in the bathroom. She joins in, their fingers dancing over their clits as they watch each other's bodies respond. Soon, they're naked, their hands exploring each other's wet, throbbing pussies. Rose's thick, straight cock stands erect, and Alina can't resist. She straddles him, sinking down onto his massive dick with a moan. They fuck hard and fast, their bodies slapping together, Alina's big ass jiggling. Just as they're about to come, someone enters, forcing them to stop abruptly, leaving them both breathless and unsatisfied.
