A seemingly innocent game of Ouija leads to an explosive taboo orgy among stepsiblings and their partners. The supernatural force drives Serena, the insatiable stepsister, to initiate a swap, pushing her stepbrother Nicky and his girlfriend Leana to explore their hidden desires with Leana's friend Berry. The room transforms into a writhing mass of limbs and moans as they swap partners and positions at Serena's command. The ouija board's eerie glow illuminates their debauchery, from missionary and cowgirl to intense doggystyle, until they're left breathless and fully satisfied, their secret taboo tryst forever bound by the power of the board.
