A culture festival filled with chaos! As each participant's desires clash, they are possessed by reality-altering markers, causing their bodies to transform into various forms of sexual fantasies. Mass orgies ensue, featuring futanari, rubber suits, and more. One girl experiences a gender swap, becoming a boy while her former self enjoys anal penetration and piston riding. Everyone seems to be having fun, but please remember not to get too carried away by the pleasure of others.
