Etna was repulsed, at first. But it seemed like she wouldn't be stopping anytime soon, with the pressure still building up in her gut. She cringed, and doubled over in pain at the intense growling in her bowels, before letting out another thundering storm of flatulence. The demon could only grit her teeth and moan at the minute long release of gas, that exploded out of her with a loud, trumpeting sound.
The room was almost becomming foggy with the noxious fumes, and she had no choice but to begin inhaling them as she sat in gastronomic distress. Her nose wrinkle at first, at the afwul aroma of demoness gas, which had a thick, overpowering odor of rotten eggs and brimstone, a rare combination that could only be expelled from the ass of a demon. She cringed with every sniff, but, somehow, it was becoming more alluring. Her stomach growled again, and Etna lifted one leg off her bed, and released a loud, burbling fart from her but, actually smiling with the release. And the moment she was through, she began inhaling again, deeper this time. The aroma was becoming intoxicating and she couldn't resist polluting the air even futher with her "Personal Perfume"
Etna jumped off the bed, letting out a small poot just from moving, before leaning down and touching her toes. Her tail pointed straight up, and she couldn't help but laugh and yell,
"Fire in the hole!"
A long, groaning fart leaked out of her butt, bubbling and sputtering as the foul gas poured out of her tight little pucker into the air around her, making it downright impossible for anyone with a nose to breathe. Anyone but Etna of course, it may have been the potion, but she couldn't get enough of this gas, and fell on her bed, sniffing deeper and deeper. She was almost drowning in her own butt fumes, and she loved it. She even peeled her tight, little black panties off her butt(Which were nearly stuck to her from the constant farting and sweating she was doing) and sniffed them. She was thrilled to find that they were saturated with her gas, and reeked something ungodly.
Suddenly, Etna had a realization. Why should she be the only one to enjoy all this demonic flatulence? It smelled so devilishly delicious, someone else needed to indulge in it with her. She grabbed her cell phone from her nightstand, and thought for a moment who she would call.
"Laharl's out on some war campaign," she remembered, "And the prinnies don't deserve such demonic scents. AH! I know, that love freak will simply adore this."
She dialed the number, and of course Flonne, the fallen angel, picked up on the other side,
"Hello, Etna? What's going on, why did you have to call me, you know I'm in the castle too."
"No reason in particular*Sniff*" Etna lied. She was so in love with her odor that she was still huffing it while on the phone, "C'mere, to my room. *Sniiiiiff*. Quickly, I gotta *Sniff* tell you something."
"Do you have a cold or something?"
"I'm fine, *Sniffsniff*, just c'mere, while the stuff's still fresh!" And with that, Etna hung up. Leaving Flonne a little more than confused. But she didn't argue, and walked to Etna's room. The fallen angel couldn't prepare for what happened next, when she was hit with a wall of stench a foot thick, that nearly knocked her on her ass. She gagged and wheezed at the afwul odor, and walked inside if only to see if Etna was still alive, a major mistake. Enta, who had been hiding behind the door, came from behind and tied her filthy panties around Flonne's mouth, forming an malodorous "Gas Mask" that choked her senses. Flonne's vision danced at the odor penetrated her very being, and soon she fell flat on her back, looking up at the ceiling. Before she passed out on the smell, though, she saw Etna, standing over her, wearing no panties under her leather skirt. Flonne reached out to her for help, but Etna smiled deviously, and squatted over Flonne, cutting one last, atrocious fart that finished the little angel off, knocking her unconscious.
Now Etna can proceed with part two of her plan, in which she
