Sébastien and Pauline's quiet night is disrupted by the arrival of alien invaders. Sébastien is captured and forced to watch as an alien shapeshifter takes his form to seduce and dominate Pauline, using powerful pheromones to turn her into a sexual frenzy. The aliens, with their dark, blue-black skin, long limbs, and prehensile tails, take turns dominating Pauline, making her experience intense pleasure and multiple orgasms. Sébastien, bound and helpless, is both horrified and aroused by the sight of his wife being gangbanged by the alien creatures, who cover her in their glittering, sweet-tasting blue cum.
