After awhile Shining had clearly more than cleaned his sister’s back, leaving it practically sparkling. Now he cringed at having to give her hindquarters a good, thorough clean. “Umm, Twily, how exactly am I supposed to do this?” He said with apprehension.

“Don’t worry Shiny just start at my rump and make your way down my hindlegs. We’re grown ponies, this doesn’t have to be weird.” Twilight said reassuringly.

Shining blushed, his erection instantly feeling tighter the second his little sister talked about him groping her curvaceous little rump. “Alright, as long you’re okay with it you know I’d anything for my LSBFF.” He said, trying to be reassuring, but failing miserably to hide the massive blush on his face and semi erect boner, sticking out from under his little sister abdomen.

“Whatever you say lovercolt , just try not to get too carried away back there.” She said teasingly, flicking her tail at him, deliberately just missing his stiff member by a single hair.

“I’ll try, but I don’t know how well that’s going to go with you teasing me like that.” He laughed back as he began to shift over to his little sister’s backside.

Shining Armour got right up behind Twilight as he began to straddle her and run his hoof over her soft curvaceous rump. He leaned into her small fragile body with his heavier frame, pressing his warm body against hers while making sure to not be too rough with his little sister, at least not right now. He managed to elicit quite a few moans and other guttural noises from the young mare under him as he kneaded and massaged at her copious little backside, running his soapy hooves over ever curve on his little sister’s ass, unconsciously giving the mare a small hooffull of light thrusts, reward by Twilight unconsciously bending just a few inches over for him.

Having just finished washing his little sister’s rump and then some Shining sighed to himself. “Well Twilly, it looks like we’re done here. You ready to go to bed.” Shining said, disappointment clear in his voice as he climbed off his little sister’s back.

Twilight smiled smugly to herself, feeling quite bold, or more accurately horny as she made one of the most courageous decisions of her life. This was a once in a lifetime opportunity, and she wasn’t ready to just give that up. “I don’t know about that, I made quite the mess of myself back there, as you saw. Do you really expect me to go to bed like that? You wouldn’t do that to your little sister, would you?” Twilight said, a slight hit of seduction clear in her voice.

“What do you mean by that Twily?” Shining replied, his blush revealing that he knew exactly what she was talking about.

Twilight’s smile grew wider, not needing to even peak back at her big brother to tell the expression plastered over his face. “This.” She said, raising her tail, clearly revealing exactly what she wanted Shining to ‘clean’ for her. Her pussy was an absolute mess, matted in thick sticky mare cum, as it winked at the stallion behind it, cover it in yet more of the alluringly messy liquid.

Twilight’s smile grew wider as she looked back her brother’s hard blush. “Again, I see no reason to make this weird Shiny. It should be no different than you washing any other part of my body. Why would it be?” Twilight said teasingly.

Despite his bright blush Shining managed to force out a response. “So you’re really okay this Twily?” He said, eagerly anticipating her response.

Twilight simply flicked her tail at the stallion, allowing her pheromones to do the talking for her as she mentally and physically prepared herself. She had no idea what she was doing, this was mad, she must have had an extremely early heat coming on she thought, how else could she justify this to herself.

With a blush bright on his muzzle Shining approach his little sister’s hot sex. “Well, if you say so Twily. I’ll treat it differently than I did your flank, which is to say that I’ll give it a good thorough clean.” Shining said sensually as he reached his hoof between the mares hot thighs, in complete disbelief at how things were playing out.

He lay his hoof at the top her vulva, just below her other tight hole, as he pressed his hoof gradually into the soft puffy flesh, slowly gliding it down the rest of her glistening slit, before rubbing her sweet little nub and gliding his hoof back up the mares tight puffy pussy to repeat the process over again. As a reward he got an overly enthusiastic moan from his little sister, who was currently leaning against the showers back wall in anticipation of things to come. Twilight didn’t attempt to hide even the slightest notice of her clear arousal, more than happy to moan loud for her stallion, for her handsome big brother.

Shining continued to play with his sister’s pussy, becoming all the more adventurous each time he reached her sensitive clit and prepared to travel once more up that beautifully tight slit of hers. He had moved on from gentle playing and prodding to something a little rougher, his hoof now pressing right into the mares hot pussy, going past her siky folds to explore the outer depths of the mares vagina and then back out, to once again tease and massage the puffy outer lips of the mares vulva as his hoof traversd the last inch or so of her marehood, before rubbing just her tail hole, and once again descending within her depths to repeat the whole process over again.

Upon reaching the mares delicate little nub rather than simply massage it as he had before he pressed down upon it, hard. Pressing his hoof hard against his little sister’s swollen clit Shining kneaded it roughly in a tight circular manner, causing the mare before him to buck her hips sporadically as she screamed out in pleasure, exciting Shining to only presse hardly against the mares sensitive nub of nerve endings.

She bucked her hips violently at her brother’s powerful kneading right up until the point where he’d pull his hoof away from her hungry little nub and instead try his best to get it far past her puffy folds and into her intame depths. She’d start to buck and scream out unashamedly the moment her brother’s hoof began to once again descend her quivering sex, heading directly for her painfully swollen clit. Despite Twilight’s loudly proclaimed delight and violent bucking driving the stallion over the edge, he just about managed to keep enough composure to keep the teasing going, taking noticeably longer upon his descent than ascent, clearly teasing the desperate little mare further. Needless to say Twilight was now moaning far louder than she ever was in the state he had initially found him, and she looked like wild animal as she desperately grasped onto the wall in support of her violent bucking and heaving. She was a complete mess.

This lasted for a good 5 minutes until Twilight just couldn’t take it anymore. Not only was it physically too arousing, the fact that her big brother of all stallions was the one with his hoof firmly in her little honeypot made the situation far, far more arousing, giving a good hint of perversity. Needless to say Twilight came for her big brother, she came hard, her marehood violently spasming as it shot wave after wave off hot mare cum right at her big brother, coming from her deepest most intimate depths, and at that moment there was no stallion in Equestria she’d rather share something so intimate with.

Shining’s hoof was thoroughly lathered in his sister’s hot mare cum. It shot right up his forehoof covering his lower leg, and dripped from the tip of his hoof. Immediately after Twilight’s orgasam began to calm down he removed his hoof from in between her hind legs, which were now physically hotter than Tartarus, as he looked into his sister’s bright, beautiful, purple eyes and began to lick her sticky mare cum off his hoof, showing her just how much he appreciated her sharing something so intimate with him.

After cleaning his hoof off he continued to look longingly into his little sister’s, his sister looking back at him as she panted. “I warned you that this was a bad idea, didn’t I? All I’ve done is make the situation far worse. Everything from your thighs to your tail hole is completely filthy.” He said, a hint of mischief in his voice.

“Oh yeah, and what is big brother going to do about that? Leaving me in such a state would have been bad enough, but causing such a mess and not cleaning it up would be completely unthinkable. You’d be quite the filthy stallion yourself if you we to do such a thing to an innocent young mare, but being my caring big brother, I know that you’ll be more than happy to thoroughly solve my little problem.” Twilight said between pants, still hanging onto the shower wall for support.

Shining merely smiled as approached his little sister’s haunches. “You know how much I’d love to help clean your little mess.” He said, bending his muzzle down between the mares fiery hot rump. He began to lick at the mares inner thighs as soon as he became in reach, gaining a content sigh of relief from his little sister as his tongue explored everywhere between her fiery haunches in slow sensual licks, he desperately lapped up all of his little sister’s tasty mare cum within his hungry maw, giving off a few of his own moans as she did so, the vibrations of which sent shivers up Twilight’s weak knees.

This continued for a few short minutes, Shining making sure to thoroughly clean absolutely everywhere around his sister’s now swollen marehood as he moaned contently into her wonderful haunches. Shortly after lapping up everything around little sister’s haunches he got a bit more bold, placing his tongue a few short inches under his little sister’s swollen clit. He then drew his rough wet tongue up the mares backside with great pressure, and at a painfully slow speed. Licking up every drop of the mares delicious nectar directly from the source as his tongue mercilessly stroked the mares sensitive little clit, paying no mind to its extremely sensitivity as it absolutely assaulted the swollen nub as hard and for as long as it possible could, taking painfully long to travel up its small mound.

Needless to say, Twilight was now absolutely screaming with pleasure as she struggled to stay on all four legs, now wholly reliant on the wall and her brother’s aggressive touch to hold her still. Another loud moan of ecstasy escape her lips every time big brother’s wonderful tongue ran over a particularly delicate part of her now painfully swollen clit, or pressed down harder against her. Her hoof had assaulted her most precious and sensitive of areas countless times, but she never had a stallion lick her back there before, Tartarus, she never had a stallion, let alone her big brother back there at all. Everything about the experience was new and exciting to her, and she loved it, she loved her big brother for giving it to her.

After a good few seconds of pleasuring Twilight’s tasty little clit he moved on to do the same to the rest of her marehood, with no less enthusiasm than he had just showed her aforementioned black pearl, although first he wanted to savour the moment, it wasn’t everyday that you got to eat out your little sister after all, and she deserved all the affection she could get. With this in mind he pulled his tongue away from her clit for just a moment, kissing it lightly before moving onto her beautiful pussy.

Shining set his lips at the centre of his little sister’s marehood, deeply inhaling her wonderful scent before he got prepared to go to the work. He then pressed his lips firmly against his little sister’s deliciously tight marehood, kissing and licking lightly at it, in worship of her beautiful sex. It wasn’t all that exciting, but nonetheless Shining became deeply enthralled within his little sister’s tantalising sex, making out with it as he would with her other lips, occasionally even biting lightly at the mares puffy folds before slipping his tounge into those same lips, playing her tight vagnial walls like a violln. He let out stifled moans, his whole muzzle pressed firmly against his little sister’s sex. The only other sounds that could be heard were the loud lapping of his wet tongue and countless moans satisfaction that escaped his sister’s other lips.

After a good few minutes of Shining’s little make out session Twilight decided to tease her big brother, desperate for him to go just a little further. “Hmmm, Shiny, not that I don’t appreciate your affection, but if you wanted some kissing practice for the prom I think you’d have had better practice using my other lips for your little make out session. How about you give me a deeper clean instead? I think you could probably see your reflection in my marehood by now.” Twilight said, moaning all throughout as she nonetheless pressed her marehood firmly against her brother’s firm tongue despite her complaint.

At this Shining took one long lick up Twilight’s marehood before giving her beautiful little nub one last kiss, pulling his face out of her glistening marehood. “Yeah, I think I know where you’re coming from Twily. If anything it’s more important to clean what we can’t see, and no doubt the deeper you, or rather I get the messier you’ll become, and I certainly wouldn’t won’t to leave one inch of you, no matter how deep, untouched.” Shining said as he began to climb onto the mares back, resting his behemoth of a 14 inch stallionhood firmly on the mares back as he whispered the last few lines sensually into her ear, sending shivers down her spine.

Hardly believing what her big brother was doing, was about to do to her, Twilight simply let a out moan and bent slightly forwards, pushing her rump an inch or two more upwards. “Hhmmm, if only we had something that could do the job.” Twilight said, her eyes superinfixed on her big brother’s massive cock.

Shining merely smiled down at her, his cock standing at full attention, like a large hot metal beam that had been held over a furnace for a good few minutes. “Oh, I think I might have something in mind.” Shining responded, taking his cock away from his little sister’s back as he began to line it up with her marehood.

Twilight could feel the immense heat and weight of her brother’s stallionhood as it left her back and began to line up to her convulsing sex. She was already so hot and aroused, she felt like she was going to cum right there and then and he hadn’t even touched her with it. The immense size, heat, and hardness of the thing alone were enough to make any mare faint with arousal, that fact that it was her big brother lovingly, no lustfully holding over her hungry marehood made it so, so much more arousing. It was naughty, it was filthy, it was dirty, it was perverted, but Twilight loved it, Twilight loved her big brother’s cock.

So, it was to noponies surprise that Twilight bent, face to the floor with her rump pointing directly towards Celestia’s sun and began moaning like her life depended on it as soon as her Brother’s hard member merely brushed against her desperate sex. The sheer size and weight of his cock imposed itself violently onto her helpless marehood, the immense heat of the thing almost burning her marehood from her clit, over her winking stantch, to her other puckered entrance, the heat racing across her nethers, setting what was already unbearable hot ablaze. She felt totally oppressed and at his mercy as her big brother’s cock aggressively imposed itself over her most delicate of places.

Needless to say, despite its immense size Shining’s cock gilded seamlessly into his little sister’s begging marehood with ease. Her pussy was thoroughly wet from both her brother’s saliva and her own lubricant, as it invited, or rather desperately begged for her handsome big brother’s cock to set itself deep within her womb. It gapped shamelessly like the hungry maw of a dog, it just needed to be filled, by him, by his cock, by his seed, she’d take anything he was willing to give her, she’d go all the way for her big brother if he only filled that hole with some, preferably a lot of himself.

Shining’s cock inch by inch slide slowly down his little sister’s tight marehood, it’s veins, bumps, and ridges scraping against her increasingly convulsing walls, playing them like a delicate little instrument. With each inch of his member that disappeared into his little sister’s irresistibly hot pussy she got a little tighter, squeezing in desperately on her big brother’s thick stallionhood. She let out low long moans as her pussy tighten around her big brother’s cock, pronouncing each ridge and veins as it scraped past her puffy black vulva and against her soft vaginal walls, playing her like an instrument.

Shining then came to an abrupt stop inside of her, sitting a good halfway inside the mare at an impressive 7 inches. He simply lay there towering over the mare for a few brief seconds as she moaned in frustration, his stallionhood almost painfully stretching the mare open, although clearly for Twilight not enough. He then tried to pull back in preparation for a deeper thrust, only to be meat by aggressive resistance as Twilight’s marehood clamped down like a hot anvil around Shining’s stallionhood, trapping it inside, and furthermore trying to lure it in deeper, as it massaged and squeezed his thick choicel, the mare on the other end of that pussy making her intentions more than clear as she let out a series of desperate animalistic moans, so extremely hungry for her big brother’s cock. Not being one to upset a mare, least of all his sister, Shining bucked hardl.

Twilight was instantly taken aback in both shock, quickly followed by ecstasy as her big brother gave her a good few extra inches with one powerful buck of his hips, sending his cock far past the medial ring and close to the hilt. His cock now sat at a good 10 to 11 inches inside the mare and its impressive outline could be seen across the mares lower abdomen, as it made a noticeable bulge from inside the mare. Twilight simply panted, finding it increasingly hard to stay on all four legs with such an immense weight pushing down on her, but regardless, she loved it, and with an almost masochistic enthusiasm she begged for more, her marehood only tightening around her brother’s stallionhood all the more as she moaned and begged audibly for her “big brother’s cock.”

Her desperate calls were answered as Shining once again, with greater force and some struggle, pulled his stallion out from most of the mares womb, thrusting back in the second he left, each time giving her a little more and going a little harder than before. At first he found the process of pulling back to rear up for the next thrust quite daunting, but with each thrust his cock massaged and weakened the mares hungry marehood, beating down its defenses both literally and figuratively as he pounded her sweet plot over and over again, each time increasingly turning her vaginal walls into nothing more than melting putty, as his little sister’s delicate pussy proved pathetically weak under the power of his immense, hot stallionhood.

This continued for a good 5 minutes, the mare under him becoming an increasingly hysterical mess as her pussy was ground down to silly putty coated in his hot pre-cum and overwhelming pheromones, claiming what was left of it as his own, while he continued to pound into the mare, much to her audible and physical delight. As his excitement came to ahead Shining took one long draw out from the mare, leaving only the tip of his hot, rock hard pulsating cock within his little sister’s marehood, before giving her one last powerful thrust, taking her to the absolute hilt at breakneck speeds, before resting his cock deep within her womb as it swelled up rapidly and coated every inch of his little sister’s womb in his hot sticky seed, filling her to the brim with his seed, as he claimed the mare under him as his own. Naturally Twilight responded back with her own equally impassioned orgasam, as she cried out in delicate as her delicious mare cun plastered her brother’s cock. It became so bad that both his and his sister’s cum began to completely rush past his own cock and gush of the mares pulverised entrance while he still lay deep inside of her womb, she was too full of her big brother’s cum, so the only place it had to go was out, as it plastered her insides, before gushing in streams down her ruined marehood.

The two simply lay there exhausted for a few minutes as they regained their breath, Shining with his cock still firmly nestled within the deepest regions of his little sister’s womb. After awhile Twilight collapsed and fell sound asleep, resisting under her big brother’s cock contently, like a little filly. Shining watched his adorably sexy little sister for awhile before eventually getting up and pulling his now flaccid member from the mare, hearing a loud slicking sound as he pulled his cock out from the mares womb.

Looking down at his little he smiled in satisfaction. Her stomach was swollen to nearly twice its usual size, completely full of his own seed and nothing but, as a small trickle of both his own and his beautiful little sister’s love juices still leaked out of mares decimated entrance. She looked so beautiful.

After a few seconds of admiring his mare, his little sister, his Twily Shining trotted over to her face, giving her a loving peak on the cheek before removing her leg caste, picking her up with his magical aura and lifting her out from the room quietly as he made his way towards her bedroom, not forgetting to quickly dispose of his magazine, not that he’d need it anymore after that. Once the adrenaline calmed down she’d probably be in quite a bit of pain, but he highly doubted that she’d mind.

Upon arriving at her door Shining contently trotted through, gently laying his little sister on the floor as he fixed her bed sheets, before lifting her back up with equally as much care and resting her exhausted body on the newly prepared bed. Once again looking down at his wonderful little sister Shining kissed behind her ear before simply whispering in it. “I love you Twily.” He whispered sweetly, smiling down affectionately at his beautiful little sister as he did so.

What does Shining do next?

He leaves Twilight with a little reminder of what happened the previous night. (Short ending)

He gets in bed with his little sister, slipping his half erect cock back into her marehood as he wraps his forehoofs around her and falls asleep. (Act two: Caught by parents and taught how to have safe sex)
