A young woman named Yara with a beautiful face covered by a heavy gas mask looks calmly into the dark room. The situation seems bizarre. Not least because she is squatting on a transparent glass plate.Under the plate, Cosmo observes the spectacle that now presents itself to him. Yara begins to press on the glass plate and then to shit on it. From below, one can see how the poop comes out and how it is even smeared afterwards.Cosmo follows the spectacle for a while and then joins in. The butt is soiled with the creamy poop and it needs no prompting. Greedily he continues to smear the poop on the dirty butt.Yara, meanwhile, lies almost impassively on her back. Only the wet shimmering between her thighs betrays her. Cosmo is focused on the brown mass and also starts to lick the ass with his tongue. In the process, his mouth gets very dirty. Finally he gets up to stimulate his cock with his dirty hands and experience a satisfying orgasm.
