He had planned out his attack all afternoon along with getting things ready to go.  Today was the day that he was going to get a little payback on his sister for the atrocities that she had committed against him in their little summer prank war.  This would be the perfect payback for changing the language on his phone, it took him a long time figuring out how to fix it.  He had spent the afternoon filling water balloons and then carrying them up to the tree house, not to mention the  water gun that he had filled with ice water.

Sitting there, peeking out of the window of the tree house, smiling as he saw his sister’s friend’s car coming down the road, his que to get ready.  “Payback is coming.”  He said as he watched the car coming to a stop and the passenger door opening.  Out stepped a tall, slender cat, kangaroo hybrid got out, his mark.  He waited for her to get to the right spot, holding the water balloon in his hand.  

“Payback!”  He yelled out as he started throwing water balloons at his sister who let out a squeak of her own as the first one hit close enough to splash her.  Before the next one was thrown she was starting to the tree house, yelling that she was going to make him eat a water balloon.  The next one missed, but the third and fourth hit her and did a fair job of soaking her.  

“You’re so dead.”  She hissed out as she got to the base of the tree, starting to climb up the ladder.

“I wouldn’t do that.”  He warned, “it won’t end well for you.”  He said with a giggle as he picked up the water gun and started pumping it a few times to get it ready, aiming it at the door.  It only took his sister a moment to get to the top of the tree and across the small ‘porch’ of the tree house to stand in the doorway.  “I warned you.”

“I’m already soaked, do you really think a water gun is going to stop me?”  She said smiling as she took a step closer.

“What if…  It was more than a water gun?”  He asked, giving it one more pump for dramatic show.

“If it’s filled with something gross and you spray me with it, I will legit kill you.”  She hissed out in warning as she took another step, waiting to see just what her little brother was up to.

“Oh it’s nothing like that, but it’s something that’s going to make you regret what you’re about to do.”  He said with a little giggle as he took aim. 

He didn’t give his sister a chance to get any closer before he pulled the trigger and started spraying her down with the icy water.  The sound that she made was something akin to a hiss, a yowl and several curses all at once.  The frigid blast of water caught her off guard but only for a moment and she was rushing at her brother, pouncing and pinning him down.

The two rolled and struggled with one another as they fought over control of the water gun, the big sister being the one that got the upper hand.  “One day, you’re going to learn that you just can’t beat your sister.”  She said holding the water gun, opening the tank and smiling as she turned it, pouring cold water on her brother.

“Th….that’s not fair.”  He whined out as he was splashed, shivering a little as the water cooled him.  “You cheated.”  He said looking up to her, his eyes wandering a little lower to her chest for just a second or two, getting a good look at her budding chest and the effect of the cold water on her nipples.

“I hate to tell you, all is fair in brother and sister war.”  She said smiling and poking her tongue out, tilting her head a little at the sight of her brother blushing and looking at her.  “Josh, why are you looking at me like that?”  The female hybrid said with a little squeak as it dawned on her, the water gun hitting floor and her arms coming up to cover her chest.

“It’s um…  Nothing, I wasn’t looking at your boobs and the nipples.”  Josh squeaked out, covering his face in a failing attempt to hide his blush.  “I’m so sorry Britney…  I didn’t mean to look that much…  I mean I didn’t mean to look at all.”

“God, boys are so gross.”  She said leaning back off of her brother, letting out a little squeak as she felt something poking the underside of her thick tail.  “Oh god.”  Britney said as she got up and looked down at her brother, starting to blush at the sight of his tented shorts.

“I’m sorry I don’t have any control over it…  It just happens sometimes, specially when I see really pretty girls…  And, and, I’m sorry.”  He whimpered out, worried that his sister was going to kill him or tell him, maybe even something worse if that was possible.

“Wait, you think I’m pretty?”  She was caught off guard by the compliment coming from her brother, thinking to herself for a moment or two before shaking her head a little, remembering something that a friend told her about the brothers and sisters should and shouldn’t be and act.  “You shouldn’t think things like that, I’m your sister.”

“But I think that you are, you’re like one of the prettiest girls that I know, you and mom.”  Josh said blushing a little as he sat up, trying to hide his arousal, not too sure why he felt the way that he did about his sister, he didn’t think that he was attracted to her like that.

“You’re so sweet.”  She said falling to her knees and wrapping her arms around him.  “If only there were more boys like you out there, I might be able to find one worth dating.”  She said with a little giggle, the two of them sitting back against the wall of the tree house.

“Wiat…  You would date me?”  Josh asked tilting his head a little as he turned to look at his sister.  “I would date you.”

“I don’t think that it works like that.  You date someone cause you really like or love them…  And when you date people that leads to other things…  And boys change when their dating a girl.”  She said, letting out a little huff, thinking about the boy that she was dating.

“I don’t see why it wouldn’t work…  I mean I really like you, and you know that I love you too.”  The male hybrid said smiling at his sister.  “And I wouldn’t change or anything like that, I would keep being your little brother and pain in your butt.”  He said snickering a little at the face that his sister was making, apparently realizing that he had heard her saying that to a friend.

“I don’t know, I still don’t think that it would work out.  I don’t think that brothers and sisters are supposed to date.”  Britney said shaking her head a little, thinking about something as she did.  “I mean…  Like I said, I bet that you would be a nice boy to date…  I know that you would be a lot better than Jimmy.”

“We don’t have to tell anyone or anything like that…  And I mean…  You could give me just one chance and we can try it out and then if it doesn't work out or something, we can go back to being just brother and sisters.”  He said with a little huff, sure that he could be a lot better than Jimmy.

“I don’t know, I’m a lot of work, and a lot to deal with at times, I mean you should know that, you live with me.”  Britney said, blushing as she actually thought about dating her brother and the different things something like that would entail.  “I mean…  I don’t even think that Jimmy can handle me sometimes.” 

“Well didn’t you say something about you thought that I would be a better boyfriend than him?  That should be prof right there.”  He said poking out his tongue a little.  “I’ve never really dated someone before, but I’m a fast learner…  And like you said I live with you so I know lots about you and all of your weird and gross habits.”

“I don’t have any gross habits.”  The older sister said with a huff.  “I’m not some gross little boy like you.”  She teased as she reached over and booped his nose, getting a little mewl out of him.

“I don’t know, you spend a lot of time in the bathroom doing who knows what in there.  I mean you are a girl after all.”  Josh said licking at the finger that had just booped his nose, causing his sister to make a face, pretending to be disgusted.

“I spend a lot of time in there getting ready, it takes a lot of work to look this good, and if we dated, or you ever date any girl out there, that's something that you would have to get used to.”  She said blushing a little, “and not matter what, or who you end up dating, I’m sure that you would make a good boyfriend.”  She said turning and planting a little kiss on his cheek.

“And I know that you would make a good girlfriend and Jimmy is so lucky to have you.”  Josh said blushing from the kiss that he had gotten, looking down at his paws as he twiddled his thumbs a little.  He knew he wanted to say something or something, but he wasn’t sure what to say or what to do.

He turned his head in time to see his sister opening her muzzle to say something, this was when that voice in the back of his head told him to make his move, to do something, to show her that he could be her boyfriend.  In a fluid motion he practically jumped into her lap and pressed his muzzle against hers.  He would admit that he didn’t know what he was doing, but he just went with felt right.  Letting his tongue slipped into his sisters muzzle, dancing and feeling around like in some of the videos that he had seen on the internet.

His sister was caught off guard by the kiss, she started to push him away, but her arms ended up wrapping around him and holding him close as she let her tongue dance around with his.  Britney’s paws wern’t the only ones that were moving around and getting a feel for someone else, Josh’s paws were busy playing, tenderly rubbing and playing with his sister’s chest.  They both knew, somewhere in the backs of their minds that this was wrong, that this was something that they shouldn’t be doing, but it felt too good for them to stop.

Britney was the one that broke this kiss, leaning back and panting a little as she looked at her brother who was blushing just as much as she was.  “I don’t know where you learned to do something like that, but you are a good little kisser.”  She said, glancing around the room before looking back to her brother.

“That felt really good…  I really liked it…  I hope you did too.”  He said fidgeting a little with his paws as he looked down at the tent in his shorts that had never really left.  “I just wanted to do something for you that makes you feel as nice as you make me feel when your nice to me and stuff.”

“I don’t think that brothers are supposed to show their sister love like that.”  She said, clearly caught off guard by the sweet things that he was saying to her, something that no other boy had really said to her, not even Jimmy, most of them just wanted to watch stuff on netflix, and not to mention the fact that they always wanted to get into her pants or something like that.  “You know…  That you can’t tell anyone that we did that, or anything that we do…  So if we dated, we would have to keep it totally on the DL.”  She said trying to think about the severity of something like this, to really think about anything that might get her mind off of the fire that her little brother seemed to have lit deep in her.

“I know…  It would be hard to keep it secret, I mean having a girlfriend like you would be hard not to brag about.”  He said happily, laying against his sister, a lot like he did when they were younger and she would babysit him.  “And…  If you don’t want to date or anything like that, I would be fine…  It would suck, but you would still be my sister and that’s the best too.”  He said, smiling at her and how she was blushing even darker.

“You’re just too sweet.”  Britney said with a smile as she kissed Josh on the forehead.  It was her turn to make a move, though her’s would be a little more bolder than Josh’s had been.  

She pulled him closer, pressing her lips against his again, their tongues going right back to dancing around.  Though this time her paws went from just holding her brother close to moving a little lower.  They started at his shoulders and traced down his sides, one stopping on his hips, the other moving along the band of shorts before slipping in to find his tip poking well out of it’s sheath.

“Br…  Britney…  Are you sure about that?  I mean…  Isn’t this moving a little fast?”  He asked tilting his head before letting out a moan as he felt his sister’s soft, almost silky paw pads teasing his tip before moving a little more to stroke him through his sheath a little.

“I’m sure.”  Was all that she said as she kept stroking him a little, feeling him quickly becoming fully hard.  “I know that I want this…  And I’m sure that you want it too…  But we can stop if you want to.”  She said pulling her paw from his pants, giving him that warm, loving, big sister smile.

“I want it too…”  

That was all that needed to be said between the two, and from there the real show was starting.  With a little coaching from Britney, Josh was out of his shirt as she did the same, and they were back to kissing.  They took their time and enjoyed each other’s tongue and tender embrace before Josh took over, following a mix of instincts and things that he had seen in different videos on the internet.

He broke the kiss and started kissing a trail down her neck, giving it a playful little nip as he kept going lower.  He kept moving his muzzle lower and lower until it found one of her nipples and started licking and suckling on it.  Letting his tongue do most if not all of the work of teasing and playing with the fleshy nub that started hardening under his ministrations.

Britney let out a little moan as she felt the tongue and muzzle teasing and playing with her nipples, looking down and watching him as he would play with one before moving to the other and back forth.  All the while that he was doing this, his paws were making short work of her belt and the button on her pants.

“God Josh, I don’t know were or how you learned to do something like this, but you’re doing great.”  Britney panted out, reaching out to stroke his cheek as he sat up to work on helping her wiggling out of her pants and soaked panties.

“Well when you have a phone…  That’s in a language you can understand…  You can learn a lot of things from videos.”  He said blushing a little as he tossed the pants and panties to the side as he went back to kissing his way down between his sister’s legs.

Once he was between her legs, he got a good whiff of her scent.  The smell teasing him and inspiring his instincts to spur him on.  His tongue lashing out and starting to lap at Britney’s soaked lips, starting at the bottom of her opening, his tongue slipping in a little before sliding up and giving her little love nub a flick as he finished the stroke.  It didn’t take more than one or two licks for her to start moaning out as she felt his tongue working her over.  She was still a little surprised that her little brother knew how to do things like this, not to mention doing them so well.  He would even switch up his tactics, a few licks would be focusing on her clit, others would be dipping his tongue into her honey pot, even lapping against and teasing that sweet spot that most people couldn’t find with a map.

“Josh, stop.”  She panted out as she looked down at her brother who was looking up to her with a confused look on his face, even tilting his head a little.

“Was I doing something wrong?”  He asked, licking his lips a little, purring softly at the lingering taste of his sister.

“Oh no, you were doing just fine…  I was just getting a little too worked up, I didn’t want to get off to fast…  Not without giving you a little fun.”  She said giving him a little wink, “lets change places and I will do something nice for you.”  She said, getting up and making sure not to get too near the windows or anything like that, she didn’t think that people would see, but better safe than anything.

“Like this?”  He asked, sitting on the floor of the tree house, leaning against the wall.  “Should I be naked too?”  He asked, his paws moving down to his tented shorts.

“Well yeah, you not being naked would make things a bit harder for me.”  She said with a little giggle as she reached out and started pulling his shorts down for him.  “Not that it looks like you need things to get any harder.”

With that joke she reached out and started stroking her brother’s cock, getting cute little moans out of him as she did.  She stroked him a few times like this before pushing his sheath back and getting a look as his cock for the first time.  This wasn’t the first time that she had seen one, just the first time that she had seen her brother’s.  She was a little surprised at how big it was, it looked bigger than some of the photos that some of the random boys that flirted with her had sent her.  She looked it over for a moment, it was long and slender with a bit of a curve to it like kangaroo boys had, but it also sported little nubs on it like the feline side of the family had.

She didn’t say anything as she leaned in and gave the tip a little lick, getting a cute little moan out of her brother, the sound made her smile as she started suckling on the tip of it.  She might not admit it, but she had picked up a few things from some movies that she had watched on the internet and like her brother, she was following them a little.  She would let her tongue circle and tease the head of his shaft before she would start sliding down a little more and then back up, before going down more each time.  She did this for just a little before she was swallowing his cock and getting a taste of the pre that he was starting to leak, a sign that he was starting to get closer like she had.

She pulled back, looking up to her brother, hearing him starting to say something.  “Britney, it feels funny, it feels all tingly.”

She finished pulling off of the cock with a little popping sound, “that means that you’re getting close to feeling really good.”  She said slipping her fingers into her pouch, looking for something.  “I want both of us to feel really good.”  She said pulling a condom from her pouch and opening it before starting to slip it onto her brother.  “Just have to make sure that we’re safe.”

He knew just what she meant when she said that, moaning a little as he felt her rolling the latex cover down his shaft.  Once she was done with that she climbed onto his lap, letting out a little squeak as she got things lined up and felt the tip of his member teasing her opening.  She took a deep breath before she started sliding down on the condom covered male hood.  She had used toys in the past, but there was something different about the real thing, it felt bigger than the toys that she had put in her in the past.  With the mix of how wet she was and help from the lubed condom she had fully taken her brother and was sitting in his lap.

“Britney…  It feels really hot and tight and good.”  Josh managed to squeak out a little at a loss for words.  His mind was racing a million miles an hour, thinking about what he was doing with his sister, that he was losing his virginity to her and how he would have it no other way.  For just a split second or two he did wonder why people say that doing something like this was wrong, but for him there was something about it that just felt so right, something about it that just felt so loving and tender, something so sweet and pure.

The two let out a moan as she started moving, she took her time at first.  She would start out lifting herself up, shivering and moaning at the feeling of her brother’s cock rubbing and teasing her walls, not to mention the little nubs that  were near the tip.  She would nearly lose control when she felt her brother’s nubs teasing that little spot in her before she would lower herself back down, feeling herself being stretched out.

“I know.  It feels really good to me.”  Britney panted out as she would slide down on the cock, sitting there for a moment before she would start moving again.  “You feel bigger than my toys, and a lot better than that vibrator that I have.”  She said, starting to bounce and roll her hips a little quicker.  “I don’t think I’m going to need it anymore if I have you around.”

There wasn’t a lot that was said between the two after that, save for a little bit of teasing about different things, some talk of sneaking into one another’s room and things like that.  It didn’t take much longer after that before the two had found their rhythm and the treehouse was filled with the sounds of the two going at it, thighs and butts smacking against one another along with the sounds of the two panting and moaning out, whispering teases and lots of I love yous and sweet words like that. 

Soon Britney came to a stop, sitting in her brother’s lap, panting a little.  “I…  Josh, I want you to really do it..  I mean I want you to do like in the movies.”  She said finally giving it away that she was just as guilty when it came to watching porn on the internet.  

“You mean…  With you on you hands and knees?”  He asked, his sister not answering in the form of talking, but getting up, shivering a little as he slid out of her before she had gotten on her hands and knees with her thick tail nice and high in the air.

The sight of his sister on her hands and knees and her butt wiggling in the air at him was more than enough to tell him what she wanted and what to do.  He slid up behind her and went right back to work, guiding his cock into his lover and slipping right back into her hot depths, getting a moan out of the two of them.  She gave him a little nod, that was the sign that he needed, in a flash his hips were bucking and thrusting against her.  He didn’t bother taking his time, slamming in, hard and fast.

She knew that she wasn’t going to last much longer with all of the teasing and playing around that they had already done, that along with the fact that he was breeding her like a rabbit in heat was quickly pushing her over the edge.  With little more than a warning in the for of a loud moan and pressing her hips back into him, she was cumming.  Her walls stated milking the cock that was pumping in and out of her, wanting all of the cum that she could get out of it, thought the condom would stop that from happening.  It was all of a few thrusts after that before Josh was moaning and panting just as loud as her, slamming in one last time before she could feel his cock twitching and a warmth trying to flood her, contained by the condom.

“I love you.”  He squeaked out, holding her tight as he came in her before the two collapsed into a heap on the floor of the tree house, snuggling close as they laid there enjoying the afterglow.

“I love you too.”  She panted out, reaching back to pet her brother’s cheek.  “I think I have a new boyfriend.”  She said with a little giggle.

The two laid there enjoying one another before a familiar voice called out to Josh.  It was his mother, yelling to him and asking if he had seen his sister, and that it was time for dinner.  He called back that she was in the tree house with him, and that they would be there in a minute, and with that the two scramble to get cleaned up, dressed and into the house for dinner, acting like it was any other day.
