I think it is some kind of ritual orgy. Everybody fuck, suck, lick, and do everything they want. There is no limits. The only rule is to get pleasure and to give pleasure. Forget about the morals, relax and fully give yourself to the great delight.

Man gets his huge cock sucked by a red-haired anime girl and his ass licked by cute brunette. The next moment redhead sits on him and rides his dick, while brunette wearing lead sits on his face and gets her pussy licked.
