Use you as a fart filter at the gym

She grabs you and shoves you deep into her panties, and you realize you’re in her panties when you see her naked asshole right in front of you. She says it’s gym day today, and she’d rather not stink up the gym. She then lets out a fart that rings your ears, and burns your nose with a rank smell. She arrived at the gym, and started working out leg day. Every time she squats, you’re pressed against her asshole, and your point blank blasted with a rancid sweaty fart. She stretched and bends, runs and sits, and any rep she did in a set, she made sure you got a fart to the face. She finished after 3 hours.
