“Mom, I'm leaving now!”

“Ok sweetie, behave!” 

10 year old Billy and his next door neighbors Sarah and Jack were inseparable since before they could remember. Sarah and Jack were twins, both 11 years old. While Billy and Sarah were usually the more outgoing of the three kits, Jack stuck to the two of them like glue when they were together. Despite being a year apart, you'd never guess the three bear cubs were so different. Finishing each other's sentences, collecting the same trinkets, even loving the same weird flavor combinations. Billy was basically the 3rd sibling for them. 

This afternoon was the day of their monthly sleepover, and the three were going to be in their basement for a marathon of the Captain Grizzly Adventure movies. Over the course of the afternoon, the three removed every cushion on the two giant L-shaped couches and turned the entertainment room into a complex fortress of pillows and blankets. A central “room” of sorts made for a cozy spot to watch the movies from, and two side rooms for sleeping were tucked away behind the couch. After setting everything up, the three were called up for dinner before the marathon began. 

Bellies full of pizza, a change into their pj's, and it was time for fun. With a tub of popcorn between the three of them, they all snuggled under one big blanket and the first movie began. One movie turned into two. Then two to three. Before the kits knew it the all but familiar call from the top of the staircase came. 

“Ok guys we're going to bed!” the twins' mom called from upstairs. “Make this your last movie and call it a night.”

“Ok mom!” Sarah and Jack called back. 

With the door's closing echoing downstairs, the three bears turned to each other and smiled. Little did their mom know that these sleepovers weren't just about movies. Billy, Sarah, and Jack had a secret. Reaching underneath the blanket, all three of them quickly took off their pj's, getting completely naked. Sarah, who was in between her brother and Billy, reached to her sides and grabbed both boys’ little dicks and began stroking them. The two were nearly identical which Sarah absolutely loved. Two 3 inch humanoid fuzzy boys for her to play with. As the quick pleasure jolted through them, the boys leaned behind Sarah's head and planted their muzzles together, sharing a sloppy kiss. Sarah giggled hearing her brother make out with Billy as their true sleepover fun began. 

For 2 years now the kits had been playing with each other like this as much as they could. Although they were young, they knew just how good touching their privates was, and how much better it was doing it together. Everything started one afternoon when Billy and Jack were relieving themselves behind a tree. Being caught by Sarah, the rambunctious girl pulled down her pants and joined them. While Jack had certainly seen his sister naked before and was mostly unphased, Billy was transfixed on her lack of boy parts. Being out of eye shot of their parents, Sarah invited Billy to touch her, followed by Jack as well. With a few feels and a returned favor from Sarah, the three of them had found a fun new game to play. It started small with touching and feeling, but the kits quickly learned to do more and more. Eventually it wasn't just touching. Within 6 months both boys had licked Sarah's tiny pussy, she had sucked them both, and the boys had even sucked each other. A few months ago things had escalated further and the three of them were penetrating each other and bringing themselves to full dry orgasms. 

This sleepover wasn't just about movies. Now that the twins’ parents were asleep it was time for a wild threesome. Once Sarah had gotten her boys nice and hard, she wiggled out of the blanket and crawled to one of their cushiony rooms. What the parents assumed was that it was a respectful girl's and boys’ side. In reality, one side for sleeping and the other for play. Watching Sarah crawl away from them, Billy and Jack stopped kissing and reached for each other's stiffies. Let out soft moans, they took a minute to enjoy each other before meeting up with Sarah. The three kits weren't prejudiced about playing with one another. It didn't matter if it was a boy or girl, or that they were siblings, it just felt good and that's all they cared about. 

“Come here, Billy,” Sarah said, spreading her legs wide as he crawled into the darker room. “Lick me.” 

Billy smiled and crawled between her legs. Wrapping his arms around her waist, he buried his muzzle in Sarah's pussy. Billy loved the taste of Sarah's special spot. It was so much different than Jack's dick. Not that he didn't like sucking on him though, too. Billy loved tasting both of them whenever he could. Starting with Sarah though was always a favorite for them both. Lapping his tongue across Sarah's pussy, Billy took turns licking across the whole thing and flicking his tongue on her tiny clit. Sarah bit her lip trying not to moan too loudly. Billy knew just how she liked it. Her toes curled as her little neighbor brought her to the edge over and over again. 

Meanwhile, Jack had sat down on Billy's butt and was humping his little dick in between the 10 year old's butt cheeks. Their short fuzzy fur causing a tickling warmth from the friction. Billy's fur was so soft and it felt amazing against his boyhood. Plus watching Billy eat his twin sister's pussy was a huge turn on. 

“Mmmmm, so sweet,” Billy giggled. “That feels awesome to Jack. You can try putting it in if you want.” 

“Oh cool, thanks!” Jack gasped. The kits were no stranger to a little penetration, but it was rare for Billy to offer so early in the night. Jack was already a little wet at his tip so positioning his dick was easier than if he was totally dry. He spent a few minutes rubbing his tip in circles around and around getting Billy wet enough. They had done it enough that he knew exactly how much was needed so he could slip inside. When enough of his minimal precum had built up, Jack grabbed Billy's hips and pushed forward.

“Ah!” Billy gasped, feeling the boy's dick slide inside him. He stopped licking Sarah and laid his head on its side getting used to Jack. 

Sarah giggled and scooted back away from them, and pushed one finger inside her now dripping pussy. Seeing her brother humping Billy was super hot. There was something about when two boys did that stuff that she really liked. Fingering herself she imagined it was her getting dicked by her brother. She would only watch for about a minute before she told them to sit up. Jack sat on his heels, while Billy leaned on him so they could keep together. Now with Jack's boyhood returned inside Billy, Billy's own dick was fully accessible. Sarah giggled again and crawled over in front of Billy. Wiggling her butt at him as she crashed on all fours, she lowered her hips until Billy's dick touched her pussy. 
“All aboard the twin train,” Sarah said, and pushed back sliding Billy's dick inside. She and Billy let out a long moan, as their sensitive parts twitched together. Billy then grabbed Sarah's hips and the three of them bumped back and forth on each other. 

SHLICK PLAP SHLUCK PLAP 

The three kits wiggled and moaned as their tiny bodies all pushed closer and closer to climax. Billy and Jack were both too young to produce anything but precum, so even as they approached their peak, they could only shiver while their little dicks twitched wildly with delight. Sarah on the other hand was more of an early bloomer, and as she came along with the boys she squirted a bit of clear liquid over her legs. Voices muddled by the couch cushions, the kits shivered holding each other before collapsing to the floor to catch their breaths. 

“Oh wow!” Sarah gasped, feeling Billy's boyhood slip out of her tight pussy. 

“You said it,” Billy sighed. As he slipped out of Sarah, he felt Jack pull out of his butt too. 

“I love movie night,” Jack mumbled, reaching down and rubbing his sensitive member. “C…can I put it in you next sis?” 

“Hehe, ok.” Sarah replied, and she crawled over Billy. Without giving Jack any more time to rest, she sat on her brother’s dick taking it fully inside her. Jack gasped causing Sarah to giggle as she grinded her hips, pleasuring him into being fully erect again. 
Billy, feeling a little left out, crawled over and straddled Jack's head. Pointing his re-stiffening boyhood to the 11 year old's lips he wiggled it, slapping his chin. Jack didn't need more than that to open up, letting Billy slide it into his mouth. Jack hummed with delight as he could still taste Sarah's pussy juices on Billy. Once again the three of them became lost in the pleasures of their innocent sex. 

SLUUUURP PLAP SHLUCK SLUUUURP SHLUCK 

After just another 3 minutes the three kits were shivering one after another again. Little members throbbing, unable to produce even a single drop of cum. Tiny pussy squirting all over her twin brother. They were in heaven, giving each other waves of pleasure which after this second round was wearing out their tiny bodies. 

Relaxing briefly one more time, the kits this time returned to the movie viewing room of their cushiony cave. Turning off the TV, they snuggled together under the big blanket. 
“You guys are the best you know.” Sarah said, rubbing her paws over Jack and Billy's soft dicks. “I'll let you two have one more round alone, I think I'm ready for bed.”

“Are you sure?” Billy asked, surprised to see his friend calling it quits already. 

“Yeeeeeeah,” Sarah yawned and curled up in the blanket. “Sorry but I guess I filled up on too much popcorn. 

Billy smiled and leaned down kissing Sarah's forehead. 
“Ok then, goodnight. Thanks for inviting me over.” 

Sarah slowly put her pj's back on while Jack and Billy crawled back to their separate cushioned room. The two boys grabbed their pj's, but left them off for the time being. Sitting cross legged they spent a few minutes before just looking at each other. Though neither would ever tell Sarah, they both secretly felt a little closer than just friends. While the kits’ secret fun time was the highlight of their sleepovers, Billy and Jack did their best to be sure Sarah fell asleep first. They both had great stamina, so even as she fell asleep, they usually went another round or two without her. 

“That was pretty crazy, huh Billy? I didn't expect her to ride us that hard.”

“Same, but man does she feel good inside.” 

“Not as good as your butt though.”

Billy blushed and reached out holding Jack's paws. Scooting closer, they let their legs spread out and then up and over each other. Now locked together, the two boys could rub their dicks together just by gently rocking their hips. Leaning towards Billy and tilted his head, Jack slipped his tongue past Billy's lips for their second kiss of the night. 

“Mmmmmmh. Mmmmmph. Mmmmm.” The boys couldn't help, but love kissing each other. While they had both made out with Sarah, they liked kissing each other a lot more. Tongues dancing together as their forbidden prepubescent love continued to blossom. 

“You think we'll still be having sleepovers in high school?” Billy asked randomly.

“Huh? I don't see why not.” Jack replied. “I really like you Billy.”

“I like you too Jack.” 

“Mmmm. Hmmmmm. Mmmmmmh. Mwah!” Another long kiss and the kits knew they wanted more. Jack laid onto his side, pulling Billy down with him. Now side by side with their legs intertwined, they both began humping. Their soft little cocks grew stiff again, grinding and rubbing together. Their breaths became moans as their movements grew faster and faster. 

“Ah, ah, yes. More, Jack. More.”

“Oh yeah Billy, your dick feels so good.” 

“Ah, ah, I'm gonna, ah, Jack!” Billy gasped, the intense pleasure of rubbing with the other bear overwhelming his last remaining bit of restraint. Shivering with pleasure for one last time, Billy's little cock throbbed uncontrollably. Feeling Billy's twitching dick against his own, Jack couldn't help but start convulsing as well. Panting and moaning their bodies were wrecked with the pleasures of their third dry orgasm in less than an hour. 

With the clock striking 11, the two boys shared one last kiss before pulling their pj's back on. Snuggling side by side together in one sleeping bag, they slowly drifted off to sleep. 

For Sarah, Jack, and Billy, this was their secret. They were all way too young to be doing anything sexual, but that didn't stop them. For the three kits, this was just another part of their friendship. It wasn’t weird at all. For as long as they stayed neighbors, they would cease every opportunity to have fun together. Whether that being a movie marathon, or a wild secretive threesome.
