Isabel is cleaning her domme's bathroom, and takes the opportunity to take some dirty papers from the trash and smell Manu's ass in each one. The domme catches her in the act, and decides to let the slave smell her ass truly, up close, but with a very unpleasant surprise... Farts! Didn't Isabel want to smell Manu's ass? Then now she will also feel the stench that comes from the domme's intestine! Each time Isabel sticks her nose in the hole, Manu takes the opportunity to push harder and release her putrid gases, one by one, leaving the bathroom stinking and imposing Isabel to fill her lungs with the stench. Isabel loves the smell of Manu, but she doesn't love the stink of her farts. Yuck!
