He couldn't take it all in, firstly he'd lost control of his body, then she let him touch her private place, and finally she did the same for him.  Only it wasn't that simple, there were such powerful feelings, he could tell Katie was having them too, and what she'd done to him that last time had felt so..  It was almost scary, the bottomless pit of pleasure he'd felt, an abyss almost like he'd lose himself in.

Finally, as if his head couldn't spin any faster, she wanted him to put his thing inside her, actually inside, where his fingers had been.  It wasn't the same, he knew that, something much more special was apparent. And then there were the dreams, something like that happened in the dreams, that part scared him the most.  Looking down, Tommy saw his erection had wilted enough to let him pee, and he did actually need to go a little.  This was much more familiar, a frequent morning curse in recent years, he aimed carefully and did his business, mind empty of all other concerns for a moment.

Finally he flushed, and immediately regretted it, she'd be waiting for him to come straight back now!  The leopard made a real job of washing his paws, pausing for a moment as he remembered his sister's exciting scent that had been on them, but it was too late.  He dried his paws and swallowed, padding quietly up to the locked door.  Tommy unbolted it as quietly as he could, as if he could somehow hide from her, then turned the handle and let himself back into their bedroom.  Panting again, he saw she was laying on her side, seemingly asleep, facing away from him.

Oddly, he hoped she wasn't as he padded quietly to their bed and then got in, climbing over her and crawling up his side of the bed.  He lay on his back panting as his head finally met the pillow, the cub didn't know what to think now.  Tommy stared at the ceiling and didn't dare look at his sister, if she was awake she'd say something.  It was still quite early and he was feeling sleepy, the cub's eyes began to close as he lay there.

"Tommy"

His eyes opened wide and he drew in a sharp breath as his sister spoke, it had been very soft but seemed quite loud.

"Tommy.." she repeated, in an 'are you awake?' tone of voice.

He couldn't stand it any more and looked over to her, to see she had rolled over onto her back too and was staring at the ceiling.  Her gaze dropped then, meeting his once more, smiling a little.

"When you gotta go you gotta go, hey Tommy?" she grinned, wanting to make this as least awkward as possible.  Katie rolled over onto her side again to face him, bringing herself quite near as she studied her brother's face.

"Huh?  Oh.."  Tommy blushed and nodded a bit, "Always bad in the mornings.."

Katie nodded, then a look of concentration passed over her face for a moment.  "Hmm.  Roll over."

"Why?"  Tommy looked at her with a puzzled expression.

She reached over and tousled his headfur in an affectionate gesture, "Because I don't want you getting a stiff neck, why do you think?"

The boy considered this for a moment, then shrugged his shoulders and rolled over onto his side to face her, unconsciously putting a discrete distance between them.  They were both still naked, but he wasn't really thinking about that right now, hanging on his sister's every word.

"Better."  She paused and swallowed before continuing, "I hope you liked what we did earlier, Tommy.  I know I-I did, very much." her voice faltered.

Tommy's eyes widened and he swallowed too, feeling a sudden surge in his groin.  He truthfully didn't know what to say, and eventually nodded, his face growing hotter.

Katie nodded too, seemingly satisfied with his reply.  She paused again to consider her words, "I'm sorry if I scared you afterwards, I didn't mean to."  Katie smiled, but then a flicker of some other emotion briefly flashed across her face and her voice faltered once more, "C-come a bit closer, I won't bite."

Tommy was going to ask why, till he saw her sidle closer to him and bring her free arm up for an embrace.  They'd never cuddled quite like this before, but he guessed he didn't mind.  Still blushing, he closed the gap between them and gave a soft sigh as their warm bodies met and their arms closed around each other.  He heard her exhale in a soft sound of pleasure and smiled with his muzzle next to hers, deciding this was quite special.  They stayed like that for some time, Tommy was embarrassed to feel more surges in his groin, but pressed together he wasn't sure if anything was happening that she might notice.

Katie gently rubbed along his side, delicate pawtips brushing at his rosettes and whiter underbelly.  It was soothing and it took some time before he noticed her motions become more focussed.  She started to slip her paw inbetween where their bodies met, moving back and forth, slipping deeper near his sensitive tummy.  Tommy rumbled softly in pleasure and unconsciously rolled away slightly, opening up a gap where his sister's paw seemed to be seeking.  She took the opportunity and slid her paw deeper, barely pretending now, he gave a little shiver as small fingers caressed the fringes of his groin fur.  Finally there could be no more pretending, Tommy gasped as his sister's paw bumped his private parts, then delicately traced all around them.

"Shhh," Katie whispered, grasping her prize finally as her paw closed around Tommy's sheath.  It was furry, soft and moist, one end of it disclosing the tip of his penis, Tommy stiffened, "Relax, Tommy.  I just want to hold your willy again.  Please?"

He grunted his assent softly and held her tighter as his penis grew hard in her grip.  He shivered as she continued, sliding his sheath right down, then rubbing gently at his testicles.  The boy was under her spell again, no doubt about it.  Katie caused him to grunt again as she gripped his erection and began pointing it outwards, away from his body. She seemed to wiggle a little close also, like she was trying to get comfortable.  But that wasn't the reason, Tommy realised as the tip of his penis bumped against her soft, warm body, making him gasp.  His sister continued to hold him and pointed it lower still, grazing along her body, until suddenly he gasped as it met something moist and yielding.

Katie nuzzled against him affectionately, reassuringly, "Shhhh.." she whispered as she began to close the gap between them and held his penis as it started sinking into her.  He whimpered and she licked the side of his muzzle, huffing and panting, trying not to cry out herself.  "Shhh, that's it.."  Katie whispered as she felt him sink deeper and deeper, till at last she pulled her paw out of the way and their pubic bones met.  Sighing with pleasure, she brought her paw around his back and made their intimate embrace even tighter.

Tommy shivered, it was unbelievable, better than anything he'd ever imagined.  She was so tight and warm, so slick, grasping his stiff penis like it may never let go.  The shivering wouldn't stop, he groaned as feelings coursed through his young body, instincts firing.  They lay like that for sometime, but eventually and without thought, Tommy started to thrust against his sister.  Little movements at first, just pulling away from her and then pushing back.  But they grew, and soon he found himself pulling out an inch, his wet shaft suddenly cold in the air, then he was sheathed in her again.

Katie gurgled, pawwing at his back, "Oh yes..   Oh please, Tommy.." as her brother finally began mating her.

Tommy made a low rumble in his throat and increased his pace, hugging his sister tightly while his hips rutted against her.  It felt so good as his penis slid almost right out of her, then he thrust it back in again, each time making their groins meet with a bump.  Every sensation was magnified, he felt the bumpy texture of her vagina against his penis, her lips clinging to him as he pushed in and pulled out.  He felt his sheath sliding up, then being forced back down as he buried himself in his sister.  He felt his soft testes brush against Katie's body until he withdrew and they hung ready.

Boy next to girl, brother and sister, they were finally consummating their love.  The boy grew faster, thrusting his hips, making the bed wobble as he mated her.  The girl clutched his back and hooked one of her legs behind him, gasping as he slipped deeper into her.  Abruptly he stopped, she groaned, and then he held her as he rolled them both over until she was on her back.

"Oh Tommy.." she whimpered as she looked up at him now, his handsome muzzle above hers, so concentrated and determined on the job in hand.

Tommy looked down and smiled weakly at her, adjusting himself to the new position.  He was still deep inside her and this just felt right now, as he settled on his elbows.  Shivering, he started to thrust once more, spotted tail twitching behind him as his buttocks rose and fell.  His sister parted her legs and made a perfect space for him, drawing him deeper, clutching at his back again as she groaned.  Tommy almost growled with pleasure as he made love to her, everything so intense, so sweet.  And yet his feelings weren't running out of control, the two times he'd squirted that morning saw to that.

They were building though, it wouldn't be long, again he picked up the pace, panting and shivering.  Looking down, Tommy saw his sister still gazing at him with affection, he bent his muzzle down and licked hers while he thrusted.  The licks soon turned into kisses, and before long their muzzles were joined like earlier.  Tommy's thrusts grew in speed, becoming urgent, he was making all sorts of growly noises of pleasure. Still kissing, the leopard's orbs were bouncing against Katie quite firmly, his penis making rhythmic wet sounds.

Katie gasped as her tongue met her brother's and he drove his stiff penis in and out of her so fast, he was much better awake.  Her chest hitched as she fought for air, clutching him, another explosion brewing in her crotch.

The young boy was losing control, his movements suddenly taking on a frantic pace as he begun rapidly pistoning in and out of Katie.  She gasped and couldn't help grunting as each thrust slammed against her, it was like he was possessed.  A low moan started in his chest, almost like a growl, rising in pitch as he mated his sister hard and fast.

Tommy started to look panicked, he broke the kiss and looked at her, still thrusting very fast and panting, "Sis, I..  I think I'm going to.."  His thrusts slowed down a bit and grew erratic, Tommy was nearly at the point of no return and fearful about squirting what he now knew came out of his penis, up into her.  Katie squealed as she felt him start trying to pull away, shaking her head and holding him to her.

"No, no, no," she whispered, "In me Tommy, you can put it all in me."

He looked confused and then hopeful as he gave a few more shuddering thrusts and then suddenly grew still, breathing in sharply.  She watched his face then, meeting his eyes as his tail came up high and started quivering.  Katie gasped as she saw it happen, his eyes grew wide, his muzzle dropped open and an expression of unbridled bliss washed over it. She felt his penis surge next, pulsing, and then it suddenly became wet inside as Tommy whimpered and started ejaculating.

Katie hissed and shook with pleasure as her brother finally delivered his sperm up inside her, jetting hard against her innermost depths.  It was too much and as he painted her vaginal walls, she suddenly went rigid under him.  Katie shuddered deeply and began to spasm all over, crying out as the intense pleasure consumed her.  She could feel the ever increasing wetness, the liquid heat from him, squirting again and again into her like lighter fluid on a barbecue.  He jerked and moaned loudly on top of her as her vagina rippled, waves of contractions now passing down his penis, milking him for every drop.

The boy's tail sawed back and forth with every twitch of his penis, each one signifying an extra squirt of seed he was putting into his sister. Eventually though, Tommy ran dry and kept twitching reflexively for some time with after-shocks, Katie doing nothing to help the situation as she too was still gripping him with the occasional squeeze.  The pair grew still after a time, both panting hard, Tommy growing heavy on top of his sister.  He rested his head next to hers and she nuzzled against it, grunting as she felt her brother's penis finally start to soften.  He murmured softly in the embrace while it happened, pressing firmly against her to prolong the moment as long as possible.

Eventually, regrettably, Tommy slipped out of his sister and he rolled off her, reclaiming his side of the bed.  Something unbelievable had just happened, he stared up at the ceiling and tried to process it. This whole encounter had just been one thing after the next after the next, each more surprising than the last, and now he'd put his penis up his sister and filled her with his stuff.  She didn't seem to mind, which was the most surprising thing, quite the opposite.  Tommy scratched his head and wondered about girls, it was almost like she was desperate for it.

Katie stared into space for a while, glowing, she felt radiant and suffused with her brother's wonderful essence, now given freely.  It pooled warmly inside her, she could feel its wetness slowly seeping out of her.  If she just tilted her hips back a little..  The cub murmured as she felt it running deeper inside again.  It was all just so naughty, forbidden (though she couldn't tell you why), Katie almost couldn't believe it was happening herself.  Her brother had proved quite willing to 'play' with her, given a little persuasion.  Would he do it again?

The girl felt a sudden surge of naughtiness and sat up in bed.  She scooted backwards and leaned back against the headboard behind their bed, spreading her legs open.  Tommy was laying right next to her, but quite unashamedly she began pushing fingers into her vagina, spreading it, trying to open up the void her brother's penis had so recently left.

"Tommy, look!"

The boy turned to look up at his sister and meet her eyes, which then flicked down impatiently.  He could see her paws were in her lap, but nothing more from his post coital position.  Struggling to break out of his daze, Tommy struggled upright to a sitting position, then he looked at his sister again.  With a gasp he put his paws over his muzzle, looking as Katie tried to show him exactly what he'd just squirted up into her.

Her puffy slit was spread wide enough that he could see the opening inside her, and trickling along it, leaking out of her was his creamy white sperm.  He shivered as she pulled one paw out, his fluid clinging to her fingers and forming sticky ropes between them and her vagina. She was shivering too, giving a groan as she slid her fingers back in.

"Can you see it, T-tommy?"  Her voice trembled, "It's all yours, I can feel it inside."  She bit her lip, adding in a quiet voice, "It feels wet.."  As her brother watched with his maw wide open, she took out her other paw and began masturbating with just one, fingers slick with sibling sperm.  Her face flushed deeply and somehow this felt most intense of all, hot under Tommy's stare.  He couldn't look away and she couldn't stop, his eyes going from her face to her groin, but mostly on her groin, while she eased a third finger in.

The noise was very wet and terribly naughty as Katie thrust her fingers in and out.  She kept glancing at her brother and shivering, his stare was so earnest, so interested, then she saw his paw gently reach and touch an erection.  That was too much, she moaned, let out a little squeal, then arched her back suddenly.  Huffing, the girl started twitching, great spasms wracking her body, it was enough to make her slide down the bed and return to a flat position.  Still her release continued and she whimpered, rolling onto her side, gasping with her fingers buried deep in her slit.

After what felt like a long time, Katie finally lay still, curled up a little, panting softly.  The only sound was her own breath, and a very soft kind of slapping noise, repeating quite rapidly.  Before she could open her eyes, she heard her brother gasp, start grunting, and then she felt something very warm splash against her small breasts.  Her eyes flew open and she watched as, hunched over, Tommy ejaculated all over her chest, eyes squeezed tightly shut as he held his penis.  It was quite thin and watery compared to earlier, she guessed he was running out of his stuff for now, it had been quite a morning.

Groaning and shuddering, Tommy thrust his hips with every squirt, and even he after he was just shooting blanks, till at last the spasms of pleasure left his body.  He fell back onto his heels and was just squatting there, wilting penis in his paw, watching as his semen gently ran in rivulets down his sister's body.  Suddenly the situation hit him full force and he met Katie's eyes with a terrified expression.  Intense embarrassment overcame the young boy and he scrambled up off the bed, before walking hurriedly to the bathroom.  Only seconds after the door slammed, the familiar sound of the shower could be heard.

Katie chuckled softly to herself and murmured with deep satisfaction as she rolled onto her back and rubbed Tommy's semen into her chest.  It was sticky as always, sadly cooling, but one of the most exciting things that had happened to her.  She hadn't seen that one coming, and hoped Tommy was OK, he'd looked a little weirded out by it all in the end.  Once the glow faded and you realised just what you'd done with your sister.. Katie stuck her tongue out, she'd done all this stuff with her own brother!  But as icky as that seemed, there was no denying how good it had all felt, and how intoxicated she was by the whole thing.  There would have to be more, of that she was certain.

After 20 minutes, Tommy emerged in a cloud of steam, he didn't look quite as troubled but wouldn't meet Katie's friendly gaze as he made a bee-line for his clothes.  She shrugged and prised herself out of bed finally, headed straight for the bathroom and showered too, preparing for the day.
