Summer was an exciting time for Leksi. The squirrel girl had always liked the carefree days of warmth away from school but this year things were different. She had started getting curious about boys and peeking at her brother at every opportune moment was just not doing enough for her any more. Thus she had hatched a plan to invite some of her friends over to go swimming by the lake. Three of the boys had agreed to come, everyone deciding to meet by the lake in the afternoon when the water was the warmest. Oh her way there, Leksi could already feel herself getting worked up. She had neglected to tell the boys that her plan wasn't just swimming, but skinny dipping. By the time she got there, all three were already in the process of undressing. One, the mouse who had gotten there first, was already in his swimming trunks. Leksi gave the trio a happy wave and tossed her bag under a tree, quickly pulling her shirt off, eager to get going. As her budding chest came into view, she kept a close eye on the boys to see how they reacted. Clearly enough, all three were watching her, though they tried to be a little subtle about it. With only some tight swimming trunks to hide it, the mouse's growing erection was the easiest to spot, though all of them were starting to pitch small tents from the display. Not willing to lose momentum now that she had gotten this far, Leksi quickly turned around and moved on to pulling down her shorts and panties in one quick pull, bending over as she did to give the boys an unhindered look from behind. Glancing back behind her, the tents had only gotten more obvious, the mouse now needing to cover himself with his hands as he blushed in embarrassment, unable to take his eyes off her. Feeling everything was going according to plan, Leksi swiftly stuffed her clothes into the bag and stood back up, pointing at the lake.
"Alright, lets get going." she said, standing naked before the gawking trio.
"But... what about your...?" stammered out one of the boys, to which she simply replied
"Lets go skinny dipping! C'mon!"

Faced with this sudden proposal along with the naked girl in front of them, the boys felt a bit trapped. There was no way any of them could every allow an opportunity like this to pass, but they were all pretty shy about just letting a girl see them naked like that. However, curiosity soon overpowered caution, and the mouse boy pushed his thumbs into his swimming trunks, yanking them down as his face got redder, his excited little erection popping out and bouncing around as he stood up. Now it was Leksi's turn to stare, her eyes locking on to the boy's crotch, examining every inch of it as she could feel herself drooling from both her mouth and her pussy. It was all the harder to contain herself as the other two joined in, finally taking off their remaining clothes to reveal another two sets of goods for the squirrel to oggle. While none of them were extremely big, she was already comparing all three, trying to eyeball whose stuff was the biggest, the longest, the best looking... at least until she got shaken back to reality by the three heading for the lake, laughing and joking to try and relieve the mood a bit. Not wishing to lag behind Leksi rushed after them, inner thighs already slick and wet before they even hit the water. All four quickly got into the lake, laughing and splashing as the initial awkwardness wore off. However everyone kept an eye on each other, Leksi eagerly watching the boys doing a back stroke with their dicks in the air, the boys diving under to get a closer look at her pussy as she tread water and so on. 

It took a long time in the water for fatigue to finally set in, but the mouse was the first to get tired enough to finally climb back onto shore. Still hard from having spent all that time next to a naked girl, he cast one more look down at his friends in the water before sneaking off past some trees, hoping to quickly get a chance to jerk off and calm down. He leaned back against a tree and sighed, grasping his wiener as he thought back to the squirrel stripping off, half closing his eyes he started stroking. However he hadn't gone unnoticed. Leksi's keen eye spotted him sneaking off and she went looking for him, arriving through the bushes to come face to face with him stroking himself. They shared a stunned silence, simply staring at each other while Leksi's hand subconsciously moved between her legs, eagerly starting to rub away as she watched the boy. He watched her go for a moment, then gathered up his courage and asked if he could touch her too. Already hornier than she remembered ever being from having spent all afternoon surrounded by naked boys, the squirrel eagerly nodded, moving her slick fingers away to let the mouse feel her up. The boy approached with a bit of hesitation, then gently placed his hand between her legs, stroking her pussy as he tried to make sense of it. He ran a finger across her lips, then slowly parted them before running another between them, amazed by the warmth he felt. She let out a little squeak as his palm rubbed over her clit, prompting him to rub it harder, making her legs shudder. She closed her eyes and swallowed a moan and as she opened them again, the mouse was on his knees, about to press his face between her legs. Before she could protest or even ask what he was planning, he started eagerly licking away. The sudden, intense pleasure hit her like a small heart attack. Her chest felt heavy and her breath stopped as if her body was focused on nothing except enjoying this new intoxicating sensation. Even at her peak it took her a couple of minutes to finish when masturbating but the sheer intensity of how good it felt to be eaten out made her come in seconds. Her eyesight went a bit fuzzy and her breath was still strained, but she managed to stammer out a request, if not demand for more. The boy happily complied, eagerly licking away as he used his hands to part her lips for better access, stopping momentarily to suck on her sensitive nub before returning to licking and back again. Leksi felt she could die at any moment and not even mind, it was the best thing she had ever felt, sending orgasms through her one after the other until the mouse finally stopped, wiping his mouth with the back of his hand as she tried to regain any composure at all, her pussy dripping all over the ground as she braced herself on a tree.
His needily twitching dick pointed right at her, the mouse asked if she's be willing to repay the favor and suck him off too. It was something he had heard about, even if he had little idea what it really entailed beyond well, a girl sucking on his peen. That was about as much Leksi knew as well, but she felt now if ever was the time to be brave and go for it. She lowered herself down onto her knees and grabbed his shaft, closing her eyes as she wrapped her mouth around it, amazed at how hot it felt on her tongue. She tried moving around to fit it in better, her tongue licking at the salty tip as her hands curiously moved to feel up the boy's nuts. Before she even realised it, he suddenly let out a muffled moan as he blew his load in her unexpecting mouth, causing her to recoil back in surprise and swallow the glob of cum, panting from the surprise. 

Before either of them had much time to recover, the two others arrived on the scene, having come looking for their friends. Stumbling upon the sight of what was going on, they couldn't help but feel jealous at the lucky mouse, their own boners still painfully untended to. Leksi was quick to grab the opportunity presented to her, very literally. She moved over to the two others, reaching out to touch their privates, examining them closely. They were both a bit bigger than the mouse, but just as warm to the touch as she ran her fingers along their shafts, watching them shiver as she got to the tip. She then moved her hands down, wrapping her fingers around both pairs of testicles, weighing them in her palms before squeezing her hands shut, making the boys squirm as she gripped their most sensitive parts a bit harder than they liked. This did nothing to dampen their excitement though, as their members remained rock hard, twitching in desperate anticipation. Still holding her grip on their nuts, Leksi moved in closer, drinking in the sight of the shivering boys and their expressions of excitement before letting go and grabbing their awaiting dicks once more, almost instinctively jerking both off still on her knees in front of them. It did not take long for her touch to become too much to bear as both boys, panting and shivering, came a small load onto their friend's arms and chest.
After a moment of recovery, all four sat there in awkward silence, not sure what to think or say. Finally, Leksi broke the ice
"Guess I should get back in the water to get this off. Last one in the lake is a slimy toad!"
It was enough to bring the carefree mood back, and the four of them headed back into the lake, leaving behind no evidence of what had happened, even though all four of them would remember it as one of the best days of summer ever.
