Chemical Gases

Saori is studying the subject of gases in chemistry, when Tay and Rebecca see the perfect opportunity to relieve their intestines and help Saori know the gases better, in practice... Farting on the girl's face! These two start farting 1ncessantly, and take off their shorts to make the holes of their asses even more free. The gases are rotten, loud and long-lasting, and Tay and Rebecca insist on farting on Saori's open mouth and tongue, so that she not only smells, but tastes of their gases. Saori gets completely disgusted with the situation and with the putrid asses on her face, and the worst happens when these two decide to fart together! Yuck!
