At 17 Kasey thought she would have more boob. She was 5'5, 135 pounds, and still sporting an A-cup that she could stretch to a B if she felt determined. That was the conversation subject as she and her best friend Joyce sat in their PJs in Joyce's den. It was 1am and Joyce's parents had been asleep for hours. As they sat together on the couch, watching the TV on silent, they chatted about everything from boys, to schoolwork, and eventually got around to comparing their bodies. Kasey thought Joyce was magnificent. While Kasey was small and petite, Joyce had a few extra pounds on her. Thick thighs leading up to her round, soft butt cheeks which bulged out of her pink pajama pants. She had a D cup naturally.
Suddenly, in the middle of a sentence, Joyce let out a rumbling fart. Her face scrunched up and she squeezed out another loud fart, which sounded wet to Kasey.
"Oh my god! Joyce I think you just ruined those pants." Kasey said through giggles. Joyce was laughing but then stood up.
"I'm sorry but I've gotta run to the bathroom, I'll be right back hun". Joyce hopped up and jiggled her way to the bathroom. Kasey was left with the smell growing in the room. She giggled a little more but found her hand had started rubbing in between her legs. She started to sniff deeper and was basically humping her hand which had started to feel moisture soaking through her pajama pants. She had no underwear on so it felt like a slippery heat chamber all over her pussy and thighs.
The smell didn't linger and Kasey felt disappointed. She idly stroked her clit, still through her pants, finding herself imagining burying her face in Joyce's big fat cheeks and getting covered in her stinky gas. She looked over at the bathroom, carefully got up and crept to the closed door, seeing lines of light shining through the cracks.
Kasey, being careful to not make noise, put her nose up to the crack of the door and sniffed. It was an orgasmic smell, but just as she was about to get her hand into her pants she heard a flush, and just barely stood up in time for Joyce to swing the door open. She looked confused.
"Kasey? What're you doing?".
"Oh um," Kasey was nervous, and smelling the scent from the open door made her a little woosey. She hoped Joyce wouldn't look down and see the wet mark on her pajamas. "I have to go now too, I was just waiting. You took forever, ha."
"Okay..." Joyce went back to the den and sat on the couch. Kasey walked into the bathroom and shut the door behind her. She lost control. She, kicked her pajamas off, sunk down against the door, legs spread open, and basked in the stink that Joyce had left behind. She felt it all over her, such a hot, deviant smell. Her hand rapidly massaged her clit while she suppressed her moans. Knowing that she was masturbating to her best friend's shit smell, she didn't care. She lifted the toilet seat and sniffed as deep as she could; cum was flowing over her fingers and legs as she worked towards a giant orgasm.
Then, she couldn't help it. Kasey let out a soft moan when she saw, Joyce had been in such a hurry she didn't realize her first flush wasn't enough. There, sitting in the toilet, was a fresh log of shit. Kasey didn't even think about it. She reached in through the cold water and grabbed a fistful of her friend's nasty poop. She raised it to her face and inhaled deeply, finally cumming, and squirting her cum all over the bathroom floor.
Kasey panted as she sat in basically a puddle of her pussy cream. Exhausted, she didn't even react when the door swung open and Joyce saw her sitting there, panting, shit in hand, sitting in cum.
"Did I hear you moan? What the fu-" Joyce stopped as she took in the scene. Then a grin spread across her face. "I thought I heard you playing with yourself. Did my shit turn you on? What a filthy slut! I didn't know you liked it so dirty." Then Joyce stepped into the bathroom and shut the door behind her.
"What're you doing?" Kasey stammered, terrified that she just got caught doing something she never knew she would enjoy.
"I'm making your dreams come true. I left the bathroom too quick and needed another wipe. Luckily I have a friend who wants to be my toilet paper."
"You do?" Kasey asked dumbfounded, still a little dazed from her orgasm. Joyce pulled her pants down and let them drop to the floor. Her pussy was moist, with matted public hair pressed all over it. Then she turned around and bent over, spreading her ass cheeks for Kasey.
"Lick me clean Kasey, I want your face buried in my dirty cheeks." Kasey, got on her knees so her face lined up with Joyce's ass. Her crack was hairy as well, and Kasey saw clumps of shit tangled inside. She reached her hands to Joyce's cheeks and pulled them apart, hearing the moist opening sound of her cheeks spreading, she felt a heat coming from her best friend's ass, and the smell was intoxicating.
"Mmm," moaned Joyce, softly, "I've been dreaming of this Kasey, please lick me clean, I'm a nasty, dirty whore that wants to cover you in my brown stink." Kasey needed no further encouragement. She pressed her entire face into Joyce's filthy, hairy ass, and inhaled deeply. The scent made her pussy drip underneath her. Her mouth opened and she made a gutteral noise of pleasure as she tasted Joyce's ass slime for the first time.
"Oh fuck yea hunny." Joyce started grinding her ass back into her friend's face. Kasey had her mouth open, shoving her tongue in Joyce's asshole, covering it in her delicious shit. Her face writhed in between her cheeks, coating it in shit stains, getting some in her hair, but she didn't care. In fact, she wanted Joyce to cover her completely with this amazing brown stink from her ass.
"Joyce I want to be your toilet paper forever." Kasey moaned. She didn't know why it made her so horny, but she couldn't help herself. It was the greatest feeling she'd ever experienced. Kasey devoured every ounce of shit Joyce had left in her crack. When it was gone she didn't want to stop, she relentlessly sucked and licked at Joyce's asshole until there was nothing left. Her knees were sore on the ground, wet, in a puddle of her saliva, Joyce's ass juice, and both their cum which had been flowing consistently the whole time.
When she finished, Kasey collapsed to the ground, with Joyce dropping down with her. They hugged each other while laying in the smelly cocktail of their liquids on the floor. Joyce found Kasey's brown-stained lips with hers and they slowly made out as they came down from the high they both experienced. As they kissed they slid around and coated each other in the cum/spit/shit mixture.
They laid for a long time before getting up and showering clean together. They didn't say anything about it the next morning, but they both knew that was just the first of many fun adventures together.
