Mike and his stepsister Selina rent the coolest place to spend some time chilling under the sun. When they arrive, they are greeted by Lucy and Jimmy, the owners’ adopted son and daughter, and their hosts during their holiday. While showing them around, the girls end up doing the unthinkable: fooling around with each other’s stepbrother in the kinkiest ways. When the misunderstanding is finally out in the open, an awkward confrontation between the two pairs of step-siblings in the living room arises. The hosts, Lucy and Jimmy, eager to maintain a perfect image for a glowing online review, insist that bonding over sex will make the vacation unforgettable. Meanwhile, Selina and Mike reluctantly agree, unsure how to handle the awkwardness of seeing their sibling being sexual with someone else. What starts as a quirky fucks ends up in a horny foursome with no boundaries and a lot of stepbrother-to-stepdaughter interactions.
