Description: Protein shakes have aided in making Silvia Rubi’s body really healthy, and this also means her gas has gusto! The whey in her shakes makes her butt blasts delightfully daunting! Once she has worked out for a while, I decide training her isn’t half as fun as sniffing up her rancid farts. Silvia’s embarrassment lessens as I have my nose up against her bikini bottom, sniffing up those protein-induced gassers so she doesn’t have to. I’m a doting trainer, aren’t I?
