Chapter 2

Minoru scratched his ear, staring at the geometry problem, and then he scribbled down a line of figures on the margin of the page, calculating the unknown angle by adding up the corners of the triangle and subtracting them from the total. Just as Minoru got to the last step in the solution, adding up the numbers in his head, his left shorts pocket vibrated, and then a small blip came from it. He looked around the quiet classroom, every one of his classmates engrossed in the math quiz. He carefully slipped his phone from his pocket and flipped the red lid open.
One new e-mail message from a contact. Minoru pulled up his inbox. The new message was from Moe. The kitten opened the message, noticing there was an attachment. The message itself, was brief.
Wanna come over after school, cutie? This was me at lunch today, thinking of you. Minoru bit his lip, penis stirring in his pants. Hanging out with Moe after school only meant one thing, as Minoru was quickly learning. Since he first visited, he'd been over twice, and he now could claim the dubious honour of having had sex with Moe in every room of her apartment, including her parents' bed, plus the hallway outside her apartment door, at the head of the stairs, and even a quickie in the train station ladies' bathroom when his train home was delayed. He opened the attached picture, and his screen was suddenly filled with a full-colour close-up of Moe's spread labia, now-familiar vaginal opening pink and shiny for the camera flash. The fifth-grader's ears flushed, bright red, along with his cheeks, and he looked closely, pinching his erection through his shorts. After a moment, he noticed the shiny drop of what had to be Moe's juices, frozen in mid-air after dripping from her vagina.
"Hey, Takahashi, what's that?" Minoru's stomach leapt into his throat, and he closed his phone over, catching the lid on his thumb, before looking at the mouse boy leaning sideways out of the seat to his right. Yuuki, the white mouse in the desk next to him, was grinning at him.
"Nothing, Sugitani," Minoru hissed, trying to whisper and avoid attracting attention from the other students. The mouse leaned over further.
"C'mon, show me. Someone mailed you, didn't they?" Minoru gave his shorts another squeeze, and then he grabbed Yuuki's ear, pulling the mouse over.
"Don't tell anyone about this," Minoru said, holding his phone against his chest. The mouse just grinned, whiskers twitching. "Got it?" Yuuki nodded.
Minoru carefully opened his phone up and turned the screen towards his neighbour, paw cupping it to prevent stray peeks for other classmates scratching away at their papers. "Whoa!"
"Shh!" Minoru pushed his phone shut and tucked it under his desk, cheeks burning. A damp spot began to form on his shorts, unseen. Yuuki's cheeks flushed a little.
"That's Moe, isn't it," the mouse whispered. Minoru blinked, muzzle dropping, all shame of having cellporn falling away for the moment. "I know her. She tutors me in English every Monday. Why'd she mail you?"
"She wants me to come over after school," Minoru admitted, face flushed. Yuuki grinned.
"Ask if I can come, Takahashi. I had to skip this week because of the class play."
"But..."
"C'mon," the mouse begged, voice quiet. Minoru pulled out his phone, and without a word he quickly sent a reply, asking if his classmate Yuuki could come along. Moe's response was almost immediate, audio blip going off in less than thirty seconds as Yuuki hung onto the far edge of his desk, counterbalancing his head as he looked right over Minoru's. Totally! Just then, the door slid open as the teacher returned, and Minoru managed to hide his phone in his shirt pocket before the teacher actually stepped into the room. Before the end of the test, he got it into his pants pocket, out of sight, but he could do nothing to help the erection that just would not go away.

Minoru stretched his arms out, shoulders lifting his backpack off his lower back. Yuuki's tail flicked as he walked beside him through the streets of Fujidana Town between Inaridai Elementary and Nishi-Yokohama Station. On their right, after several identical residential lots, the boys encountered a sports equipment shop. Yuuki stopped and darted over to the window, looking at the racks of soccer balls stored immediately past the other side of the front window. "Hey, they got the World Cup balls early!"
Minoru stopped, setting his arms down, and he walked over. "Really? The guy told us they weren't going to be in stock until next month."
"I know! I'm definitely coming here on Saturday to buy one. I get my allowance on Friday." Yuuki grinned. Unlike Minoru, the mouse was a big soccer fan, but he rooted for foreign teams on the international level. He wasn't the best soccer player, himself, but ever since he joined the student body at Inaridai in second grade every teacher who ever had him had failed to break him of the habit of hogging the ball and trying to do head bounces and chest traps with it. A lesser-known fact was that the young mouse did require corrective lenses, as he was near-sighted, but he wore contacts so he could properly head the ball.
Minoru pulled out his phone and checked the clock. "Come on," he said, tugging at Yuuki's black backpack. "We're going to be late for the train to Moe's."

Minoru's ears folded back as Moe's labia slipped against his crotch, and he mewled, feeling that hot, snug grip on his whole shaft as the over-sexed teenager sat on his shaft. A face full of perky breasts muffled his cries, his partner hilting him inside for their fourth mating of the afternoon. Yuuki stood over them, caressing his large fuzzy testicles, pink shaft fully erect. The mouse boy certainly had a quick trigger when it came to getting stiff after orgasm. Moe continued to bob over Minoru, tail wagging over her back end.
"Yuu, why don't you take care of that, cutie?" The mouse squeaked and crawled back behind the shiba, rubbing his penis against her asscheeks as they bobbed over Minoru's crotch. Minoru just moaned into Moe's breasts, fairly delirious from the whole experience. "No, Yuu, put it in big sister right here," Moe said, going still. Minoru humped, instinctively trying to keep up the pace, but suddenly something felt different. His penis inside of Moe's vaginal passage suddenly got pushed against her frontal wall by an intruder as Yuuki squeaked, gripping Moe's hips. Minoru tried to open his eyes, but he only got boob against his muzzle. He shivered, holding still, as he felt what had to be Yuuki's penis press in against his. The feeling was different, tighter, and he couldn't help but try and pull out. However, as he did, he moaned, pleasure even more intense, as Yuuki hilted inside their shared bitch. Minoru's hips lifted, pushing himself in all the way, just as Yuuki pulled back with a jerk, and Moe growled.
"Mmmf, I'm so wet for you boys!" The boys didn't speak, aside from grunts and sucked-in breaths, and they kept that pace, a jerky, unskilled pistoning, one boy pushing in as the other slipped back. The feeling of another boy's penis rubbing against Minoru's  was strange, but he tried not to think about it, worried that it might turn him gay. However, he kept forgetting about it, briefly, giving in to the feelings of a much-tighter-than-usual Moe. Yuuki was squeaking, close to orgasm behind Moe, and she was simply in a state of bliss. Suddenly, as Minoru was close to orgasm, hanging onto Moe's back, he thrust in just as Yuuki pulled back, and the slick stroke over the sensitive underside of his penis was too much for him to resist. Yuuki didn't last much longer, hips pushing against Moe's ass a moment later, pumping thick globs of pubescent mouse seed deep into the slutty girl, washing over Minoru's penis during his still-dry orgasm.

Yuuki slid back first, letting Moe get off of Minoru, the boy still supine on the floor after his first double-male penetration with a girl. Minoru groaned, stretching, and he picked himself up, completely naked. He noticed his classmate staring at his flaccid penis. Yuuki was better-endowed than him, but not nearly as big as Kazuo, and Minoru looked away, cheeks blushing, when he realized he was checking out another boy.
"Hey, Takahashi. Um... you ever do stuff with guys?" The mouse was talking to him. Moe was bent over at the fridge, vagina leaking mouse semen into her thighs while she stole a cold beer from her father's stash. Minoru's ears flicked.
"Er, uh..."
"You never tried it? With another guy?"
"N-no..."
"Yuu-cutie, Kazuo's his big brother." Yuuki's cheeks flushed.
"O-oh." Minoru blinked, looking between his recent sex partners. Moe was grinning as she sipped at her drink. Yuuki just masturbated, slowly.

Just as Minoru got his shirt buttoned up, Moe handed him her phone. On the screen, a badly-lit video played, showing a white-furred ass on the left side of the frame. Whatever fur that ass belonged to, their tail was not fluffy at all. Suddenly, from behind the fur, a male moved into the frame, and the unknown male began to push his dick into the other fur's tailhole. The white-furred one didn't seem to resist at all. Minoru's cheeks flushed bright as he took in what was happening. The thirty-second video looped, showing the penetration again, and he looked up at Yuuki, facing away from him and bending over to pull his briefs up.
Moe nodded. "That's him, all right." She took her phone back, giggling. Yuuki's cheeks just flushed as he stood up and covered his ass with his underwear, turning to look at the other boy.
"If you're not into it, Takahashi, that's cool. But, you should try it." Minoru blinked. He was less concerned about his friends suggesting he try homosexual acts with another male; what bothered him is that his brain didn't immediately reject it.

Minoru leaned back against his seat as the train rolled past KM House B. He wasn't letting Yuuki's comments bother him, leaving them out of his head for now. More puzzling was Moe's suggestion as he went through the turnstile at Wadamachi Station. Moe told him to ask Kazuo to soap him up at bathtime.
Minoru's train came to a halt and he stepped onto the platform and made his way out of the station and up the road to home. When he got home, Kazuo was already in his room, doing homework while punk made his speakers jump. Minoru dropped his bag off in his room and changed into his newest River Crabs shirt and his pyjama bottoms, and he went to run the bath, before mother got home.
As he adjusted the temperature, filling the tub, his tail flicked. Kazuo already did soap him up--the boys washed each others' backs every night when they bathed together, except for when Kazuo was out with his friends or at his new weekly cram school session.

"Kazuo, bath time! Let's surprise mom by having it early!" Kazuo's music decreased in volume, and he turned to look at the door, chewing on a pen.
"I got the bath ready. Let's have it early and surprise mom so she doesn't have to rush us to finish so she can have one."
Kazuo turned his music off, tossed his pen on the desk, and spun his chair around. "Why not," he grunted. "Tired of History right now anyway."

Minoru wiggled his toes, wondering when the appropriate time would be to say it. His fingers ran through Kazuo's soapy back fur, pushing the suds around and lathering everything up. The older boy just relaxed, used to the routine of bathing with his younger sibling. Minoru filled the stiff plastic bucket with water from the small tap at his side, making sure the water was warm enough, and then he dumped it over his brother's shoulders, quickly pushing his fingers through the mottled patches of fur to rinse out the soap. A second splash was enough for Kazuo's back to be free of suds, and Minoru spin around on his stool, facing away. "My turn."
Kazuo squirted a big dollop of soap onto his paws and lathered them up before massaging the suds into Minoru's shoulders, working quickly down his back. Minoru's shoulders rolled into the touch, the boy always enjoying the intimate touch of his brother. Despite how they might argue and fight like siblings do, the boys got along rather well. One reason was their almost-daily ritual of bathing together. Kazuo's fingers stopped at Minoru's waist, by unspoken agreement, and he lathered the kitten's back up, getting a good foam. Minoru turned his head, smiling.
"Hey, Kazuo, can you soap me up?" The older feline paused, his paw at his brother's side, covered in suds past his wrist.
"Who got you to ask me that?"
Minoru blinked. "Moe did."
Kazuo shrugged, rolling his eyes. "Yeah, I can do that." He scooted his stool a little closer, behind his little brother, and his paws slipped around, starting to soap up Minoru's chest. The kitten sat still, unsure of what to expect, but this would certainly be considered soaping up.
Kazuo squirted more soap onto his paw and lathered his palms up, and his touch moved to Minoru's belly, despite the kitten already having rinsed his own washing job out. Kazuo's fingers calmly descended, further, until two fingertips curled under Minoru's testicles, palm kneading his penis, and his ear got a good lick from behind. "H-hey, whoa." Kazuo just continued, with a little grunt, touching sensitive spots even Moe hadn't explored. His penis quickly rose to erection, and he mewled, rather unsure of what was happening. Kazuo's fingers curled around his penis and began to stroke, lubricated by the soap suds, while he fondled his brother's balls. "Wait, Kazuo, what're you doing?"
Kazuo's movements stopped, but he didn't let go, holding his brother's penis. "You asked me to soap you up."
"Then why're you... I mean, how come... what're you touching..."
Kazuo sat back, taking his paws off his flustered sibling. "Mino, did Moe explain why she wanted you to ask for a soap-up?" Minoru shook his head. "What'd she tell you about it?"
"Uh, nothing? Just that I should ask you?"
Kazuo laughed. "That girl's crazy," he said, shaking his head. Minoru scooted around on his stool, paws pressing his erection down, trying to hide it.
The taller boy grinned, rinsing his paws under the tap and then giving Minoru's ears a pet. "For boardies, soaping up is a code word for having sex in the bath. Because you're not likely to get caught if you're fast enough."
"O-oh..." Minoru's ears flattened, and he looked at his older brother, rather confused. Kazuo turned the tap on and filled up the rinse bucket. He then poked his brother's shoulder, holding the bucket over him. Minoru tilted back, paws still on his crotch, and Kazuo dumped the warm water over his brother's flat chest, rinsing all the suds away.
"Don't be scared, Mino. I wouldn't do anything you didn't want. Here. Have a seat." Kazuo slapped the raised rim of the tub. Minoru climbed up onto it, covering his erection. Kazuo stood up, naked, and kicked the stools aside. He knelt down in front of his little brother, smiling.
Minoru watched, as calm as he could in the situation, paws on his shaft. He looked away, realizing he was staring at his brother's endowments. Every other night, it'd been of no consequence, but tonight, sitting on the tub, looking down at his kneeling brother, that healthy teen dick stood out prominently, although Kazuo wasn't erect. 
"Close your eyes." When Minoru did, Kazuo very gently took Minoru's paws by his fingers and drew them away from the boy's eight-centimetre penis, exposing it to the air currents in the bathroom. Minoru whined, but Kazuo shushed him, voice soft. Suddenly, Minoru's eyes opened wide as something warm and slimy, quite unlike Moe's familiar openings, pushed around his penis. The alarmed kitten looked down, only to find his older brother's lips sliding down his penis. Minoru's toes curled, the tingling feelings in his penis quite pleasant even if his head was trying to tell him how weird and uncomfortable it was for his own brother to give him oral sex. The conflict between top and bottom left him helpless as lips touched his scrotum, his brother taking his whole shaft into his wet, warm muzzle.
Kazuo's paws slid to and rested on the younger kitten's thighs, quite near his rump, and Minoru's paws slowly found their way to his partner's head, kneading at his ears with kittenish affection. Kazuo's head began to bob, lips squeezing, and this left Minoru gasping as another argument started between north and south. Eleven-year-old toeclaws pressed against the tiled outer wall of the bathtub.
Minoru's head finally tilted back, and he let out a whimpering mewl of pleasure. "Mmmf, Kaz, it's good!" Just then, that warm, wet feeling left his shaft with a wet slurp, and Kazuo grinned up at him.
"Have you ever fooled around with another guy, Mino? I mean, besides now." Minoru's ears perked.
"Well, uh...no." Kazuo straightened up, crouching on his feet.  Minoru looked, noticing his brother now sported a sizeable erection, much like when he had been mating with Moe.
"Wanna mount me, then?" Kazuo chuckled, turning around, tail lifted. The older cat leant forward on all fours, showing off his trim ass, wrinkled pucker, and healthy pair hanging between his thighs.
"Wh-what? Ew!" Minoru shook his head, paws letting go of the tub to hold in front of his face, and he lost his balance and fell into the hot bathwater with a splash. Kazuo stood up and walked over as the kitten quickly stood up, drenched and dripping and sputtering for air. The older boy stroked his erection, just waiting for Minoru to recover his composure.
"It's not ew. It feels great. It's even better than with a girl sometimes." Minoru looked up at his brother, ears flopped down, water dripping from his whiskers. "Really. I went and hung out with Moe last Monday, and she was screwing this cute mouse, and he wanted to do it with me. I didn't want to tell her that he was tighter than she was."
Minoru blushed. "Really? And he could take it? In his butt?" Kazuo just nodded.
"I'm not gonna stick it in yours, though. I want you to stick it in mine. If you don't like it, you can stop, all right?" Minoru's erection bobbed, above the water surface, and the kitten's own fingers closed around it. 
"Uh... uh huh."

Kazuo's tail brushed against his brother's waist, and he looked over his shoulder, on his knees, leaning against the edge of the tub. He was holding his breath. Behind him, Minoru was kneeling, about to touch his penis to his older brother's anus. When the eleven-year-old made contact, a paw cupped his rump, encouraging him onward. "Just push. Won't hurt me. And, it's not gross. Pussy is slimier and weirder."
Minoru took a deep breath, and then he pulled on his only sibling's hips, pushing forward as he tried to stretch past that puckered bud. With the help of a tug on his ass, Minoru's glans pushed past his partner's sphincter muscle, and instinct propelled him forward all the way with a throaty, breathless moan, until his hips slapped against that ass. As Minoru started to roll his hips back, that strong ring of muscles clamped down hard, and he just shivered and held still, caught in the pleasure. When Kazuo relaxed his muscles, the kitten slowly pulled back, looking down with a timid mewl as his shaft slipped back from his brother's body--clean, aside from a very slight discolouration. When he looked up, he caught his brother looking at him.
"You're a wuss, Mino. Get busy." Minoru frowned, and pushed forward, as hard as he could, burying all eight centimetres back into his cheeky brother, producing only the slightest groan from the cat. "Just keep doin' that, bud."

Minoru felt a tingling in his belly, different from whenever he'd mounted Moe, which was a tingling in just his balls and shaft. The tingling spread, catching up to his tired hips. He gasped, trying to come inside his brother, trying to overcome his own anxiety about the situation and just orgasm to get it over with. Kazuo's paw moved against his belly, stroking his own shaft, and he panted. "Mmmf... close, Mino?"
Minoru's breath caught and he gulped. "K-kinda," he answered. Kazuo flicked his tail.
"I bet Moe showed you that video she took of me fucking that mouse without telling me. She's been showing it to everyone." Minoru's ears perked, thrusting slowing.
"Video... you fucking... it was you who did Sugitani?" Kazuo just nodded. Minoru's fingers curled in Kazuo's damp fur, and he started rutting his brother hard, as hard as he remembered the video was. Kazuo's sphincter gripped down, trying to bring the boy off.
"Then he... mmf, he had a turn with me, but he wasn't this good." Minoru's ears flattened, and he suddenly tensed up, shaft prodding against Kazuo's prostate gland, hammering it in short bursts until his orgasm overwhelmed him. For Kazuo, a mere pinch at the base of his scrotum, against his perineum, was enough from there, and he ejaculated onto the wet tile floor of the family bathroom.

After dinner, Minoru went to his room to do his homework while Kazuo finished the last of his History assignment and watched a movie with Father. After forty minutes, Minoru put his pencil down on the blank worksheet with a sigh. No matter what he tried, all he could think of was Kazuo. He'd penetrated his own brother. Everyone knows brothers aren't supposed to mess around like that. Kazuo seemed all right with it, but what was wrong with Kaz? The kitten could only conclude that both he and his brother were incurable perverts, and it was only a matter of time before Mother and Father would confront him. And what about Yuuki? He wasn't related to either Kazuo or Moe, but he was having sex with both. Was his classmate trying to hit on him for gay sex in Moe's apartment this afternoon?
Minoru shut his workbook and laid his head down on his arms. He pushed his math workbook into his backpack, turned out his desk light, then the room light, and climbed into bed, still dressed, disgusted with himself. As he drifted off, praying for no dreams instead of the filthy visions he'd been having of Moe's breasts, butt, and box, and would now likely include taboo gay sex, he pulled the covers over his head. All he could hope for is that Yuuki would not talk to him about it in class tomorrow.
