Choose Your Own Adventure Sparklecest

...his unopened issue of Playcolt Weekly. His parents were out shopping for the day, his sister no doubt hidden behind a colossal tower of books, and he had nothing but a warm shower and a vast assortment of fertile young mares from his magazine to keep himself company. He subconsciously licked his lips and sped up his pace at the thought.

He only slowed his carefree pace upon coming within a few inches of the bathroom door, eagerly reaching for the handle with his magic as he gripped his magazine affectionately, until all of a sudden he heard a loud prolonged, very painful sounding moan coming from inside the bathroom. Half panicking, thinking somepony may have injured themselves, but conscious of how inappropriate it would be to invade somepony’s privacy otherwise he reached for the lock, thanking Celestia that it wasn’t magically sealed.

He turned the lock slowly, evermore nervous at the prospect of potentially making a mistake, or worse, being caught doing so. After unlocking the door he gave it a slight nudge with his forehoof, making sure to make as little sound as possible before peeking around the corner.

His face instantly lit up in a thousand different shades of red at what he saw. Far more explicit than anything in his relatively tame magazines, and moreover far more real, his sister stood there, her whole body sensually dripping with hot steamy shower water and sweat, bent over with knobbly knees as her hoof aggressively assaulted her own wet, hot, puffy pussy, from the top of her outer folds, to the bottom of her clit, everywhere in between, and everywhere in between, her hoof relentlessly pressed and prodded at her poor marehood.

Shining just stood there as his brain tried to process exactly what he was seeing. He had never directly seen a mares private parts before, not including brief glimpses behind the occasion mares tail, but this was something entirely different. Rather than a brief glimpse stolen from a cheerleader at his school, rather than the altogether vanilla shoots from any magazine he had ever dirtied, he was being fully present to a young fertile mare, bent over, weak kneed, and begging with her ferocious hoof and painfully swollen marehood to be taken, to be taken by any stallion available, to be taken by him if necessary. The sight, the smell, practically even the taste of a young mare in her prime hitting him for merely a few hoof steps away, the sight, smell, taste, and fertility of his little sister…

’Wait’ his mind thought, slamming into a brick wall of reality as it did so. ‘This is my sister, my Twily, this is wrong! What am I doing.’ He thought hurriedly, although never taking his eyes off that same sister for a second. ‘Oh come on, as if you’ve never thought about it, as I’ve you never stroked yourself silly after catching the briefest glimpse of that pussy when you were younger, or your mothers for that matter.’ A slightly more perverted part of his mind shot back. ‘But this is different, this is my sister, and here I am, drooling over her like predator.’ He shot back, defensively, although noticeably quieter and with more indesion. ‘Really, accidentally peaking is worse than intentionally squinting your eyes to catch the extra quarter inch, the extra millisecond of sweet incestuous pussy, on her birthday as she leans over to blow on her candles, after Heartswarming as she climbs up the last step take the final decorations down from the tree, on a particularly windy day as a brezze lifts her tail ever so slightly and brushes against that sweet little marehood of hers, at…’ ’okay, okay, I get it I’m a sicko! You happy?’ He admitted to himself. ‘But she doesn’t need to know about it, no pony bu…’

Just before he could reassure himself that he still had that shred of dignity that came in the form of the ignorance of others, the distinct sound of a mare ferociously pleasuring herself was replaced with a ferocious scream, followed by a loud painful crash.
