Looking down at his sister’s cute little rump there was one thing in particular he couldn’t keep his eyes off, that of course being the mares plump little tailhole. Twilight’s had a perfectly round, puffy dark purple rim that shimmered beautifully under the reflective water of the shower, and her hole itself was perfectly cute and puckered. Indeed, it already looked well prepared for a stallion, and he could hardly imagine the owner of such a delectable tush minding too much if he were to just admire it.

Smiling with a slight hint of mischievous excitement Shining floated over a clear bottle of shampoo as he continued to keep his eyes firmly fixated on his little sister’s curvaceous rump, and the deliciously puckered entrance that lay tantalisingly between her two cheeks. Taking the shampoo he squirted out a good dod of the stuff onto his forehooves, leaning against the side of the shower wall for support as he began to slowly coat his thick shaft with the slippery liquid. He felt his whole stallionhood quiver and throb in his own two forehooves as he slowly began to stroke his hard length, occasionally letting out a soft grunt as he strained his to get a better look as his sisters back entrance.

Having fully lathered his cock in shampoo Shining grinned widely, trotting casually over to the mare before he grabbed her rump in his hooves with a loud soapy ‘slap.’ He didn’t waste much time in pulling Twilight’s rump up and positioning her face towards the ground, as he too got himself into the proper position, towering over the mares limp body as he lined up his stallionhood, pressing the head against her puckered tailhole as he prepared to take what was most likely his little sister’s virginity. ‘I can hardly believe that I’m actually going to do this, but she just looks so tight and cute, and it’s not like I’m going to hurt her, she’ll love this.’ Shining pointlessly tried to relieve himself of any moral doubt, knowing that he had already gone way too far to pull back at this point.

He gave his little sister’s rump a quick squeeze with his hooves before grunting as pushed the first few inches of his cock within her tailhole. He was surprised at how easily Twilight’s ass managed to accommodate his thick length, he struggled a bit at first, initially trying to get his flare into her tight backside entrance, but after that it was most smooth sailing, as the shampoo allowed his cock to sink deep into the mare with only a little coaxing. ‘Well, either you’ve had some practice at this or your unconscious body is just far too relaxed for your cute little tailholes own good.’ He thought to himself as he began to thrust into the mare, groaning as his medial flare slid past the mares rim and into her warm entrance.

He continued puffing and panting, heaving irregularly as his pace increasingly became more, and more erratic. “Oh fuck, Twily! Your ass is perfect!” He shouted rhetorically as he took a firm grip of the mares little squishable rump and began pounding away at her ass, as hard as he possibly could. Increasingly as he began to slam away at the mare, roughly bottoming out within her every two seconds or so, her arousal became known, as the walls of her tailhole began to close in on the stallions cock, becoming all the more tight as he tried to pull back out, and appreciatively massaging his cock inwards as he prepared to slam back into her.

Throughout their, or rather his little fuck secession only three sounds could be heard throughout the entire bathroom, the sound of Shining panting erratically as he desperately pounded away at his little sister’s tight ass, the sound of him screaming out as he began to thrust into her, and the sound of his heavy balls slapping against the mares sensitive pussy as he bottom out in her hard, often sending her a good half inch forward, until her limp body was being firmly pounded away against the bathroom wall.

Shining gripped onto his little sister’s ass tightly as he felt his cock begin to tighten and his balls swell. Screaming out loudly Shining moaned as he pounded into his little sister’s tailhole for the last time, his heaving balls slamming painfully against the mares delicate little marehood as his flare began to swell up and wave after wave of the stallion’s thick cum pulsed through his shaft, filling his little sister’s tight ass up to the brim as he held her body down hard against the ground with his powerful frame, determined to fill her tailhole until his little sister’s stomach burst with his hot seed.

Letting out one last frustrated moan as he forced the rest of his seed into her Shining immediately dropped his little sister’s body the second he finished, gravity pulling his cock out from her pulverised tailhole as his shaft slowly slipped out of her. Twilight fell, once again spread across the floor like a pathetic mess, albeit this time the work of a virile stallion was clear on her unconscious body. Small pools of the stallion’s seed leaked out from the mares tailhole, her cute little belly slightly swollen with Shining’s impressive work.

Smiling down at his little sister as he rode his afterglow before slowly trotting back over to her unconscious body. Leaning down towards her Shining kissed Twilight behind the ear, whispering soothingly into it. “You won’t remember this Twily, but know that your big brother loves you, and you have an amazing little rump.” He said, before running his hoof over his little sister’s soft curvaceous little rump and leaving silently.
