Struggle

You gripped Hana's ass, eliciting a yelp from her. "Ah! S-Stop that!" She gasped, struggling to keep her weight on top of your face. "You. I'll fart on you! Just give up!" You began to overtake her, her weight slowly coming off of your face. With just a little more effort, you'd be able to push her off and reverse the situation, maybe give you a bit of your own stink.

PFFFFFFFFFFFFFFFFFFFFFFFFFFFFT!

A massive, roaring fart exploded from Hana's butt. You fell back, coughing from the smell. Hana sat on top of your face now, sneering. "T-take that! Told you I'd gas you if you tried to get me off. I warned you!" A ripe, eggy smell filled your senses. Hana trapped you beneath her butt, holding you down as more of the gas spilled out of her.

PFFFT!

PrRrRRRrRrt!

"Heh. Like my farts dummy? Told you to give up! But you stupid boys act so stubborn in the ring. Now to just finish you with my gas~" Hana slapped her ass, coating you in the gross smell of her farts. It all boiled down to how she finished you now.
