The stepbrothers' dildos defeat the heartless dildo of two girls.

Curious friends climb into a box that is clearly hidden for a reason in Phoebe's stepmother's bedroom and find a large rubber dildo inside. Their excitement grows exponentially, and the girls start fondling each other's pussies and using the dildo for its intended purpose... when their stepbrothers come into the room. They are shocked by what they see, but the girls are so horny that they drag their stepbrothers into a group incest orgy.
