Your step-daughter's three best friends are staying over for the night in your big cozy mansion downstairs in the basement together. They're playing truth or dare amonst each other and Claudie dares Brooke to wander upstairs wearing nothing but her lingerie and flaunt herself around the house in front of you. Too embaressed by the dare to follow them, your step-daughter stays downstairs, while Claudia and Mia eagerly watch Brooke strip down to her bra and matching panties and follow her upstairs as she takes a lap around the kitchen and into the living room, where you're watching TV and drinking a bottle of wine. All three girls have had an eye on you for a while now, but now that they're 18, they've decided to go all in on it, together.
