When Jade's invited to another party at her friend Madison's house, she knows she's in store for an exciting adventure. But when she arrives at her house and sees a four-sided curtain hanging from the living room wall with a one-foot diameter hole cut in each side, she squints her eyes, unsure what Maddie has planned.
After Madison divides the partygoers into four groups and positions each group on separate sides of the curtain, she chooses one random participant to go inside the box and strip down. A few moments later, Jade's eyes bulge when she sees a man's penis sticking through the hole. When Madison randomly chooses another guest to stimulate the man from the other side of the curtain, the room is soon filled with the sound of loud moans and groans while the stranger behind the curtain is sensually caressed.
Just when Jade thinks the game get any more erotic, Madison chooses another random guest to enter the cage, and this time, she sees a woman's naked butt pressing out of the hole. When Maddie asks Jade to take her turn stimulating the woman, she doesn't hesitate to get on her knees and begin to lick and caress her hidden partner. The fact that neither one knows the identity of their other person only adds to the mystique and excitement of the encounter.
While Madison systematically mixes and matches the unsuspecting partners with boy-girl, girl-girl, girl-boy, and boy-boy pairs, the guests become increasingly excited awaiting their turn behind the curtain. When Jade's turn finally arrives, she's thrilled when her partner turns out to be a transgender woman with both sets of fully functioning equipment. While everybody watches to the two lovers panting in escalating sexual pleasure, Jade soon learns that half the fun is guessing who's on the other side...
