After over a year in the making, the 11th installment of the popular series "Premium Farting" is finally here! This time, Rei Mizuna takes on the series' first-ever "forced fart sniffing machine," wearing a mask connected via a tube directly to her anus. She is shown reacting realistically to the stench of her own farts, tearing up, sobbing repeatedly, and nearly losing consciousness. The video delivers an immersive experience, making viewers feel as if they can smell the farts, complete with extreme close-ups of her hairless anus.
