Reeder sucked in a breath through his teeth as his penis twitched and squirted thin strands of cub cum on the back of Emily’s nightgown as she slept. He stroked himself harder with his paw, squeezing as much out of himself as he could, his retractable footclaws digging into the carpet while his orgasm quaked through his body. He wiped the last drops from his spent erection with his paw, coating his fingers, then licking them clean. The salty tang of his own cum made him shiver. He turned back from the sleeping girls then tucked himself away back into his undies and crept back to the stairs, where Alex was waiting. The two boys returned upstairs.
"I did it!" he announced as he entered his bedroom. "I did your dare, now it's my turn!" He looked around the circle of four other boys, as Alex returned behind Reeder to join them on the floor. They were all about his age with the oldest, Tommy, being nine. Four of the boys, including himself and Alex, were clad in nothing but their undies, and the other two were nude and both sporting erections. 
"I dare you, Jimmy…" pointing at a small seven-year-old Wolf who was still in his undies, "...to...umm...go downstairs into the girls' slumber party...and put your peepee into one of the girls' paws...and keep it there for ten whole seconds!"
"Okay, I can do that!" replied Jimmy, amidst the gasps from the other boys. 
"You gonna come time me?"
"Yep."
"Okay, let's go."
The two boys left the bedroom and crept back down the stairs. Jimmy stood at the foot of the stairs and surveyed the living room where the girls were sleeping. Two girls were sleeping on either side of the couch, another in a reclining chair, and two more were sleeping on a mattress made from blankets on the floor in front of the couch. Emily—who was on the left side of the couch—was closest, but her paws were hidden under her blankets. Reeder had already "used" her in his last dare anyway, and the stain of his drying jizz was already fading, even to the boys’ powerful eyesight. The two cubs ducked behind the wall dividing the living room from the stairs. As they watched, one of the girls who was sleeping on the floor rolled onto her side to face the boys, and her paw moved out from under the blankets.
"I pick her," Jimmy whispered, pointing to the girl who he thought was named Tass. "Get ready to start counting."
Jimmy sneaked over to the girl, while Reeder watched from the foot of the stairs.
Jimmy took one last look around the dark room before pulling his slight boyhood from the opening in the front of his briefs. Right away, it began to poke out from his fuzzy sheath, growing out bright pink. Jimmy gulped and oh-so carefully lifted Tass’s delicate paw by the wrist and eased it home. Then with a quiet sigh, he wrapped her fingers around his fully-grown erection, wincing as it twitched in her paw. Then Reeder moved up closer to see, and started to count.
"One...Two...Three..."
Jimmy studied the girl's face for any sign of movement.
"Four...Five...Six..."
Jimmy's heart was beating fast and loud in his chest, so loud he worried the very sound would alert the girl to their dare.
"Seven...Eight...Nine..."
A big clench in his nethers sent clear boy-nectar to bubble up at the pointed tip of his doggy cock, threatening to dribble down the girl's paw with any slight movement.
"Nine and a quarter...nine and a half...nine and three-quarters..."
Jimmy threw Reeder an angry look while Reeder just grinned back.
"Ten!"
The moment he won, Jimmy placed the girl's paw back and fled back up the stairs with Reeder, not even bothering to stuff his dripping boyhood back into his undies.
Jimmy re-entered the boys' bedroom victorious and boys cheered and congratulated him when Reeder confirmed he completed the dare without incident.
"What was it like having her paw on your peepee?" asked Alex, one of the boys that had earlier foregone wearing clothes.
"It felt really nice; her paws are a lot softer than mine." The room giggled at this and Jimmy joined them. Jimmy realized that he was still poking out of his undies, so with a shrug he pulled himself back in and dropped them completely and threw them into the pile with the other two boys' and joined them in their nudity.
This time it was Jimmy's turn to pose a dare to one of the other boys. 
"Let's see...I dare...Alex!" He announced pointing to the naked Rabbit that asked about his dare earlier.
"I want you to...squirt into your own mouth!" and the room erupted in giggles again, except for Alex who just looked taken aback by Jimmy's request.
"H—How? I can't reach it..." He then struggled to bend his head between his legs, rolling himself over in a somersault.
"I can't do it!"
"I know how," said Jimmy. "Grab his legs Alei."
The second naked boy, a black Cat, stood up and crossed through the circle to hold Alex's ankles. With Jimmy's instructions, and Alex's protests, Alei held Alex's lower body while he was doubled up over himself, and with some flexibility, they managed to get his fuzzy white sheath within a few inches of his mouth.
Alex groaned. "This is very uncomfortable, guys," he muttered into his boy-parts.
"It'll feel good soon, just wait," said Jimmy as he moved beside Alex, and Jimmy squeezed Alex's sheath between his thumb and forefinger and began to slide it over his soft, pink flesh.
Abashed, Alex cried out, "I can do it myself!"
"I gotta do it 'cuz I gotta make sure it goes in your mouth remember?"
Alex squirmed and squeaked from Jimmy's ministrations. Alex's boyhood swelled and became harder between Jimmy's fingers, the tip extending further out, reaching ever closer to Alex's mouth. At maximum girth, Alex went for a lick and let out a surprised squeal as his tongue flicked against the tip of his own sex. Alex groaned again as Alei bent his lower body further over himself, but got over his discomfort as his lips latched onto the tip of his penis.

All the boys were amazed at the sight in front of them and cheered him on as he suckled himself. Jimmy continued to rub the shaft while the tip was in Alex's own mouth. The Rabbit boy moaned and squealed up until his inevitable climax. His curled body writhed and jolted but he kept himself in his mouth the whole time, eyes squeezed shut as he came. His throat bobbed, swallowing his load of bunny seed then dropping his head and falling over sideways to the floor, spent and breathing hard.
Alex sat up with a groan, licking his lips and grimacing at the taste in his mouth.
"Uh...I guess I did it," he said.
"That was awesome!"
"Are you okay?"
"What did it taste like?"
Alex ran his tongue around the inside of his mouth, analyzing the taste and texture. "Kinda like...salty milk..." All the boys laughed at this. "It's my turn to dare someone now, right?" Then a sudden, single knock at the door made the boys start and hasten to cover themselves.
"Hello?" Reeder, this being his house and also one of the few boys still wearing clothes, asked the door. No answer. Reeder approached the door and opened a crack and peeked out. An indiscernible shadow bolted down the stairs at the corner of his vision.
"Umm, I think we need to make downstairs off-limits," he said, closing the door with a soft click. "I think one of the girls woke up."
"Awww," went the room, disappointed that their game got ruined.
"I'll sneak down and have a look." And Reeder slipped out of his bedroom.
He padded with feline grace down the short hall and around the corner to the stairs—WAM!
Someone coming up the stairs sent him sprawling onto his back. When his vision focused he could make out a face staring down at him in the dim light.
"Lily?? What are you doing up here?" Reeder whispered to his sister, exasperated.
She scoffed. "It's my house too, you don't own the second floor," she snapped. "...And I need to use the bathroom."
"Um...what for?"
She gave him an annoyed look. "To pee, doofus, girls need to pee just as much as boys do, y'know." She rolled off of her brother and stood back up.
It was Reeder's turn to scoff now. "Yes, I know that...But...I mean why can't you just use the one downstairs?"
"Um...you really don't want to know, trust me..."
He climbed back up to his paws and adjusted his underwear more securely, prompting another annoyed look.
"Do you really need to run around half-naked like that? It's so juvenile..."
"Is not! You used to too, y'know, 'member? You're only saying that now 'cuz you gotta cover your chest 'cuz of your boobies!" Reeder laughed at his sister.
Lily made an indignant squeak and crossed her arms over her chest. "Sh—shut up! You're just a dumb boy, I wouldn't expect you to understand!" She stormed into the bathroom with a huff.
Still giggling, Reeder spoke into the door, "And 'sides, be lucky that I put on undies at all when I left my room; the rest of us boys are nakie!" A soft crash came from the other side of the door sending the boy into another giggle fit.
Giving his sister some privacy to pee, Reeder re-entered his bedroom. "Don't worry guys, it was just my sis—" he stopped mid-sentence at the sight of Jimmy and Alei bending Jeremy over double in imitation of Alex's trick before, while Tommy and Alex watched, the latter sporting an erection. "—ter..."
"C'mon it's so close!" said Alei.
"I'm just not...flexible enough!" Jeremy groaned from the strain, his face turned red from the blood rushing to his head from his upside-down position.
“You’re a Cat like me, we’re supposed to be flexible!” Alei teased.
"I think the problem is that his peepee is too small," Jimmy pointed out as he reached to stroke it, making Jeremy squeal.
"H—hey! That's no fair, I'm a year older than you!" Jeremy protested.
"So, Reeder, what did your sis want?" asked Tommy, breaking Reeder's stare at the boys' unusual game.
"O—oh! She just had to pee, I guess."
"You have a bathroom downstairs right? Why couldn't she have just used that one?"
"That's what I asked too, but all she said was 'You really don't want to know', whatever that means."
A mischievous glint appeared in Tommy's eyes. "Oh? Sounds like we should investigate! Whaddaya say?"
"I dunno...The bathroom is across the living room where all the girls are, we'd get caught for sure." 
"We'll just make somethin' up, 'sides it's YOUR house, you have every right to walk through it right?"
"I guess so..." Reeder said still not convinced, and turned his attention back to the other boys in the middle.
Jeremy was fully hard now, but still just an inch short of reaching his lips. Jimmy was undeterred by this and continued to stroke Jeremy's cock with vigor, as if trying to stretch it longer with just his paw. Jeremy’s squirming became more urgent under Jimmy's grip and began mewling in distress, but before he could get any real words out his cock twitched in Jimmy's paw and coated Jeremy’s lips and chin with his own milky white cum. Alex and Alei cheered and Jimmy squeezed, coaxing every drop out of the Cat-cub's young body. Jeremy moaned and trembled through his orgasm. Alei let Jeremy's legs go and, with a thump, Jeremy fell flat, breathing fast and wiping his face with his paws and licking them off, grimacing at the taste of his own seed.
"C'mon Reeder, put some clothes on and let's go downstairs to investigate." Tommy had already put his shirt and shorts back on and was offering Reeder his own.
"Fine, fine, okay." Reeder took his clothing and dressed. "What about them?" he asked, indicating the rest of the boys.
"Psh don't worry about them, they can entertain themselves without us, now come on, before the girls stop doing whatever it is they're doing!"
Reeder and Tommy slipped out of the bedroom and started for the stairs but paused when they saw the light shining from the bathroom door. Reeder approached the door and whispered into it. 
"Sis, you still in there?" He pressed his ear up to the door but still no sound came through. Just as his paw took the doorknob to open it, Lily's voice hissed through.
"D—Don't come in here!"
"Are you okay in there sis?" Reeder asked, starting to sound worried.
"Yes I'm fine! Get out of here!"
"Okay okay, I'm going..." And the two boys went.
"What d'you s'pose that was about?" asked Tommy as they creeped down the stairs.
"I dunno but if it's 'girl trouble' I don't think I want to know."
Tommy grinned. "Agreed."
They reached the bottom landing of the stairs and peeked around the corner, and sure enough, the downstairs bathroom light was on and three of the girls were missing, one of them being Lily, of course. They watched Emily, who was sleeping on the couch, for any sign of alertness. The other sleeping girl, Tass, was just below her on the floor. When they were satisfied that both of them were asleep they moved into the room as silent as they could manage towards the bathroom door. When they were within a few feet they could hear the girls whispering and giggling. Tommy gave Reeder a curious look. Reeder just shrugged at him, then his ears perked up as if he heard his name.
'I think they're talking about me’, he mouthed and pointed at the door then at himself. He stepped right up to the door with care and pressed his ear against it. 
"—der should be off-limits, it's not right," one girl said.
"She didn't say that, she just left," another replied. "Where did she go anyway?" 
Reeder held up a 'two' and pointed at the door. Tommy nodded.
"She better not have told the boys what we're gonna—hold on shh!" Reeder blinked, confused. Then, a second too late, stepped back from the door as it was yanked open and paws grabbed him and hauled him inside.
Blinded by the sudden brightness of the bathroom, he was unable to see his assailants, then a towel was tied around his eyes. A paw pressed against his mouth as he was jostled through the large bathroom and placed on what must be the toilet seat. Another paw grabbed his crotch and the tips of claws poked through his shorts. More paws on his shoulders spun him around and bound his handpaws together with what felt like some kind of silky ribbon.
"Make any noise and I'll squeeze, understand?" Reeder nodded quickly, and the paw on his mouth was removed.
"What do you want!? Urgh—" Reeder groaned as the girl acted on her promise and squeezed the boy’s fragile bits, the tips of her needle-sharp claws piercing through to his skin. He gulped and tried again. "W—what do you want...?" He whispered to his captors.
"Much better." Her grip relaxed, but her paw remained in place. "Don't worry little guy, we just wanna play," the girl said, making it sound like a threat.
"No Moon, we can't! That's Reeder, Lily won't—"
"Lily isn't here, and she never said he was off-limits."
"I didn't think she had to, he's her brother!”
"Okay fine Ritsu, leave if you want, I won't stop you."
There was a long pause. She sighed and said, "I'll stay, but don't hurt him!" Reeder gulped again.
"Fine, I won't “hurt” him," Moonblossom let go of Reeder's crotch. "Happy? Now let's see what Lily's li'l bro has to work with." Moon giggled with equal parts sweetness and malevolence. "And remember, any loud noises and..." she brushed a clawtip over where the boy's fragile bits would be.
"Stop teasing the poor thing Moon, and get this over with," Ritsuka said.
Moon shrugged off the chastisement and began to undress their prisoner.
Moonblossom wasted no time in divesting Reeder of his clothing, and he didn't try to resist; he even scooted forward on the toilet so she could unfasten the tailslot of his shorts and underwear, and raised his arms when Ritsuka took off his shirt. Moon didn't hesitate to pull his pants right off, leaving Reeder sitting exposed to the fur for the first time to a pair of girls he didn't even know. The boy tried to cover himself with his paws but Moon’s got there first. She rubbed and fondled his fuzzy white-furred boyparts, making Reeder squirm and wince in pain when her claws scratched against his testes.
"Awh, what a cutie!" Moon giggled, bringing heat to Reeder's face. "But we need to get you stiff, you can get stiff can't you?" Reeder nodded.
"Good! Now let's see..." Reeder jumped as a finger touched the base of his pouch and moved up along the seam, up to his little pink tip that poked just inside his fuzzy sheath. He shivered as it popped out into the cooler air.
"Thatta boy, come on out," she cooed, tickling the base of his penis. Reeder squirmed and gasped as he grew in front of the two girls, and within a minute he was at his full two-and-a-half inches.
Two fingers slid up and down Reeder's exposed pink flesh.
"Oh Ritsu look! He's got little nubs! I bet those'll make a girl feel good, huh?" Moon pointed out, brushing a finger over the spines making it throb.
"It's a Cat thing, I knew they had them but I've never seen them in person." Ritsuka touched his spines also, adding to his pleasure.
Ritsuka saw the enjoyment in his face. "How are you doing, Reeder? Starting to feel good, hm?" Reeder nodded. 
"That’s good. Don't mind Moon, she gets carried away sometimes, we really do just want to play a little bit. Sorry if we scared you, we wouldn't really do anything bad to our best friend's little brother." And she kissed his cheek, making Reeder's heart flutter and anxiety melt. 
"Y—You could have just asked," said Reeder, and Ritsuka giggled.
"Maybe next time, cutie."
"Shh, enough chatter; I'm going in…" Then something warm and wet wrapped around Reeder's spiny member, the feeling of her tongue and lips making it obvious what she was doing. His whole cock was engulfed in Moonblossom’s muzzle. Reeder let out a pleasured moan before he could stop himself. 
This feels incredible! Her tongue is so hot! I wish they removed this stupid towel over my eyes so I could see though! He wriggled his handpaws against the ribbon that tied them together, but he couldn’t reach it with one of his claws to sever it. Surrendering to the delightful ministrations of the girls, he let his head loll back against the tank of the toilet.
Ritsuka giggled. "I think he likes it!"
The warmth was removed with a wet slurp, and Reeder shivered again, but this time from the cold open air. 
"Of course he does! What guy wouldn't like getting his dick sucked? Even if he is still a little kid. Have a taste, Ritsu." 
He didn't have to wait long until another mouth enveloped his throbbing cock. Reeder moaned again, never wanting this feeling to end.
"Nice, right? Best boy I’ve ever blown off. Hey, Ritsu, move over, I wanna try something else now," said Moon. Reeder heard the rustling of clothes and snaps being unfastened.
"Um, Moon? What do you think you're doing?" Ritsuka asked, removing herself from Reeder's shaft, leaving him out in the cold again.
"Don't worry I'm not gonna do..."that", I just wanna feel..." Moonblossom sat down on the boy’s lap, their bodies almost pressed together. Then something hot, even more so than her mouth, pressed up against his cock, rubbed and grinded up and down grating against his sensitive spines. He moaned in bliss and shuddered as his nose picked up a strange scent, both strong and musky, yet somehow feminine and right in a way he couldn't explain. Then he became aware of her panting and shuddering gasps.
"Ohh I was so right! His barbs are incredible! I wanna feel them inside!"
"No Moon, don't! You can't do that!"
"He's just a kid! It’s not like he’s going to hurt me with that little thing, I'll be fine!"
Moonblossom leaned forward and whispered in Reeder's ear, "Trust me kid, you're gonna enjoy this..." She shifted over top of Reeder’s lap, lining him up with her pussy, then sank down on his cock, taking him inside her body. Reeder moaned at the hot tightness, like nothing else he’d ever felt. Moon swore under her breath and rocked her hips, working Reeder’s cock in and out of her wet pussy. The two cubs were moaning, panting messes of horny fluff, and within minutes Reeder was cumming harder than he ever had in his life. Moon wasn't far behind him, the girl quaking in his lap, her inner muscles gripping the squirting cock inside of her. Her hips thrusting back and forth, desperate to extend their passion as long as possible. 
When the heat of their sex waned, Ritsuka helped Moonblossom up onto shaky legs, letting Reeder’s shrinking cock fall out of her. Moon cleaned herself up and Ritsuka went to help Reeder. He was as dazed and dizzy as Moonblossom was that he didn’t care when Ritsu used another towel to wipe down his wet, matted sex and crotchfur.
“By all Aberdeen, L’Sara, and…uh…whatever you Cats are called, Reeder…that was hot!” Ritsuka spoke up for the first time since her companions’ vigorous mating started.
“Hah…hah…Tannis!” Reeder added, his head resting against the toilet basin again, lungs sucking in air like a fish out of water.
“Yeah, them.”
“L’Sara, Ritsu! You look like you peed your pants! Were we that exciting for you?” Moonblossom said.
Moon cackled, presumably at a bit of non-verbal communication from the other girl. “Tell you what, since you’re my good friend, I’ll “help” you out with that, once we put the kid to bed, okay?”
“Hehe! Okay, deal.” Reeder didn’t know what the girls were talking about, but he was too exhausted to puzzle it out at the moment.
"Well, did you have fun little guy?" Ritsu asked him. He nodded back, unable to form words. "Let's get you back upstairs, okay?" He nodded again, gratefully accepting the girl's help in getting his clothes back on. The girl unbound his paws, and scooped him up into her arms before he collapsed, carrying him over her shoulder out of the bathroom.
She deposited him upstairs at his bedroom door and kissed him between the ears. 
“Have a good night, cutie. It’s my turn now, hehe.”
Reeder untied the makeshift blindfold and wanted to ask her what she meant, but all he saw was a bottlebrush Fox tail retreating around the corner as the girl dashed back downstairs.
I never even got to see what they look like…

Reeder took a deep breath then entered his bedroom. To his surprise, all his friends were clothed and listening intently to a story Lily was reading to them. Some of the boys were sleeping, or nearly there. Lily beckoned him to enter.
"It's time for bed. I thought it would be better if you came back to a quiet room, without any...questions." 
"Thanks sis, you're the best," he said, and leaned into a hug.
"You too, li'l bro." She hugged him back. "Off to bed now."
"'Kay,” Reeder felt about to pass out on his footpaws as she shuffled to his bed, stepping over the other boys sprawled on the floor.
"By the way, Ritsu just invited me and Moon to her home next week, and she wants you there as well. I’ll let her know you said yes," she quipped with a wink as she left, leaving Reeder standing blinking at the closed door with a funny fluttering feeling in his stomach.
