Len, sighing happily as he relaxes next to his sister, reflects upon the events that led him to his own personal paradise.
TWELVE HOURS AGO
Len was poking around in Rin's room, as usual, searching through her laundry. Her clothes still carry her wonderful smell, and her pants harbor even more wonderful odours. Her ass must smell so good~
He always waits until she's busy, either shopping or recording a new song, when he'll have as much time as he needs to satisfy his urges...
"Oh, Rin... I wish you were mine..."
Len does the same thing as he always does, taking out his penis, by now usually erect, and starts masturbating over Rin's laundry.
He sometimes wears her clothes, he sometimes smells them, he sometimes even tastes the more pungent parts, all while obsessing over his sister and her various smells. But there is one thing he's always wanted to smell, and never got the chance...
"Len, what the FUCK are you doing!?"
There's something new...
"R-RIN! I C-CAN EXPLAIN!" stutters Len, panicking, red and sweaty, sticky cock in his hand.
Rin, looking like she's about to explode, pushes him out of her room.
"Just stay out of my room you pervert!" she screams, slamming her door shut.
Len run's into his own room and closes his own door, taking his still erect penis out and finishing what he started. "Ah! Rin...!" he moans to himself as he ejaculates, his sticky white substance covering his belly.
Meanwhile, Rin starts satisfying herself too... but in her case...
"Mmh! C-Come on!!! Hnngh...!" she pushes and groans as she begins filling 'her' underpants. She stole a pair from Len months ago and she always uses it for her special secret...
The underwear squelches, the hot, soft scat coming out the top and legs, leaving Rin with a horny smile on her face.
She throws herself onto the ground, landing on the back of the underpants, squishing the shit into her crotch area.
"Oh my god, why don't I take laxatives more often? I've never felt something so good!" she says to herself, shifting her weight around while fingering her dirty pussy, already dripping wet.
The door opens. "...Rin, I... came to..."
Len stops in his tracks. He smells shit. He sees his sister. His sister is sitting down in her own shit. His own sister is sitting down in her own shit, masturbating... in his underpants.
Rin is visibly shocked, one hand down the pants, other hand under her ass. Her face is red, and her eyes watering. "Len... I..."
But Len was already gone. His heart was pounding. Is it possible!? It must be!
TWO HOURS AGO
Len stares at his sister's door, face red and chest fluttering. He steps inside.
"Rin? Are you okay?" Len asks, searching the room for his sister.
"Go away, dispshit! I don't deserve your concern!" she yells from under her bed covers, clearly having recently been crying.
Len sighs. Now's his chance. He lays beside Rin and hugs her. "It's okay, Rin... I know exactly how you feel...".
Rin uncovers her head and faces her brother. "You do...? You don't love me... not like that..."
"Actually, Rin..." Len takes a deep breath and presses his lips to Rin's.
Rin is taken aback. Her biggest crush, her best friend, her own brother is kissing her. On the lips. And all she can do is deepen it. She slides her tongue inside. She tastes her brother. She caresses the inside of his mouth with her tongue.
Len eventually breaks the kiss, and after catching his breath, asks; "Why were you shitting yourself, Rin?"
She instantly starts freaking out. "It's not... It's... I..."
She's silenced after a loud farting sound...
Len smiles. "Me too."
Rin brightens immediately, and hugs her brother tightly, while pushing fresh scat into her pants. "Len, please! Nngh..."
"Anything for you, sister!" he says, locking her under his legs. "Ready!?"
She nods.
Len grunts and a loud wet fart resonates throughout the bedroom. He smiles happily, and his sister takes in the odours, hypnotized by the awful awesome smell from his ass.
Len pushes, and a very soft, sloppy shit slides into his pants, causing them to bulge outwards. Rin presses her face into his pants, the shit soaking through and sticking to her face. She licks her lips, tasting the rotten scat and moaning.
Len knew that this would be a good night.
PRESENT
Len stands up, getting dressed, when he feels Rin's arms around him. A distinct smell and sound follows...
"My brother... my lover..."
