The upper floor of their kinky haven transforms into a BDSM paradise. Christie, her massive tits encased in latex, commands Summer to kneel, her hands bound behind her back. Erik, in leather, feeds his thick cock into Summer's mouth, fucking her face as Christie whips her back. They flip Summer onto all fours, Erik's cock plunging into her tight ass while Christie teases her clit, making her writhe in pleasure-pain. They switch, Christie's strap-on replacing Erik's cock, filling Summer's ass. They fuck her together, Christie's tits bouncing, Erik's hands on her hips, until Summer collapses, spent and used, her body marked with their pleasure.
