Fuck her in the ass (smell fetish)

Aang’s about to step forward when his eye catches on his discarded underwear. Smiling, he leans down to scoop them up.

Meanwhile, Toph quivers quietly while suspended in the air. Between being cut off from her earthbending senses, her sore ass, her aching cunt, and the humiliation from Aang’s words, Toph’s body and head are a hot mess. Unable to form a response to Aang’s taunts, Toph vaguely tries to wriggle her way out of the ropes when she jerks in surprise.

Without warning, a damp, bag-like cloth is pulled around her head. Before she can make a sound, a head-spinning, musky smell reaches her sensitive nose. Unbidden, the shortstack moans while rapidly inhaling the sweaty, cloying odor. Her big breasts and jiggling ass shake wildly as she twists in her bondage while huffing in the cloth’s scent. As she finally realizes what was pulled over her head, Toph blushes in renewed shame even while her pussy gushes even further. Unable to help herself, the powerful scent from Aang’s underwear arouses her even as tears of humiliation form.

“Figured if you enjoy being a smelly, little Pig-bitch so much, you might as well enjoy the smell of my sweaty crotch and ass.” Aang laughs wildly.

Swinging back behind her helpless body, Aang finally plants both hands on the earthbender's fat, red ass, spreading it open.

The horny girl jerks in surprise but a small whine quickly escapes as she realizes her needy pussy might finally be getting railed. Despite her expectation though, Aang doesn’t bother with his teacher’s wet pussy.

Still intent on getting back on his obnoxious friend, Aang slams his throbbing dick into Toph’s spread asshole without hesitation. Ignoring her pained squeal, Aang groans in pleasure as the tight hole gives way for his dick. With a hungry gleam in his eyes, Aang wastes no time thrusting back and forth into her asshole. Each hard thrust sent his pelvis slapping against Toph’s sore ass. The feel of her soft, jiggling meat clapping against him each time excites him even as Toph squeals.

“Wait! Ohh! Too big. Ahh! Ohhh!”

“Too big? Show some backbone Pig-bitch.” Aang laughs while slapping remonstratively on her drum-like ass. As he pumps back and forth, he alternates between each thick ass cheeks with either hand, enjoying how she tightens with each blow.

Even as Toph feels like she is being split apart from the large dick jamming into her ass and her ass burns with heat, she can’t help but moan with pleasure. Each penetrating thrust causes her to forcibly inhale, bombarding her more and more with Aang’s musky scent. The cloying odor sends her head spinning while lighting up her body with arousal. Despite not being stimulated at all; her cunt is now gushing with desire. Even while assaulted with humiliation, Toph feels herself climbing to a climax under Aang’s butt-pounding.

Finally, as Aang releases into her stretched asshole with a shout, Toph’s own orgasm surges through her, causing her to cry out in pleasure through Aang’s sweaty underwear. Hanging in the air, Toph shakes as her orgasm continues to wrack her body while Aang delivers a few more hard thrusts to her ass. Her squirting pussy coats him with slick juices. He finally pulls out as her orgasm subsides. Satisfied with his taken reward, Aang gives Toph one more sharp spank before moving away.

“A-huh, you’re much better like this Pig-bitch. Good work.”

Not hearing his soft footsteps, Toph hangs listlessly for almost a minute before realizing that Aang has left her there, disheveled with cum running down her spanked ass and men’s used underwear pulled tight over her head. Recovering lightly now that she is alone, Toph calls out nervously.

“Aang? Hey! Is anyone there? Somebody get me down from here!”

After several minutes of calling, Toph finally breathes a sigh of relief as she hears footsteps approaching.
