Choose Your Own Adventure Sparklecest

Twilight had been caught in the most compromising position possible, all the more so considering it being right in front of her big brother. Needless to say the shock caused her to lose her balance in the extremely soapy shower, leading to her banging her head against the showerhead, and once again against the hard tiled floor as she went down. Her injuries weren’t serious, but they’d leave her completely knock out black for at least a good hour or two, and dizzy and prone to memory loss and confusion for a good few hours afterwards. To add to the embarrassment she left, sprawled across the shower floor, tail raised and legs spread wide to either side, leaving absolutely nothing to the imagination as she lay there, her little marehood still dripping and swollen, pressed against the bathroom tiles.

Shining just stood there, shocked, worried, but for whatever strange reason all the more aroused, as he felt a physical stirring in his loins, his cock practically pulsating at the sight of his little sister, lying there, completely unconscious, completely vulnerable. He felt a pang of guilt, but the other side of him couldn’t deny how he felt.

Shining then trotted over slowly to Twilight’s limp body, tracing his eyes between her hind legs and finally over her rump as he passed by, before coming to a stop right in front of the unconscious mare’s face. He bent down to inspect his little, making sure on one hoof that she didn’t need any immediate medical attention and on the other that she was truly out of the count and not just disoriented.

‘What am I doing?’ The stallion thought grimly to himself. ‘You know exactly what you’re doing, you little pervert. Just as I told you, you have the hots for your little sister.’ He replied back to himself. ‘Could you stop doing that!’ He demanded. ‘Uh, why the hell am I talking to myself? Did I hit my head as well or something?’ The stallion thought. ‘No you didn’t, you’re just now being given an opportunity to prove what kind of stallion you are. You’re perverted fantasies are no different here, the only difference is that now you can try them out for real, and poor little Twily would be none the wiser.’ He replied to himself. ‘What, no! How could yo...I even think of something like that. Twily’s my innocent little sister, and furthermore, she’s seriously hurt herself.’ Shining contemplated his predicament for a few long minutes, one side shamefully turned on by his sister’s unconscious body, the other chastising himself for doing so.

After a few minutes of trying to get his little sister to wake up the voice at the back of his head returned. ‘Looks like she really is completely out of it. Maybe you could use the opportunity to get a better sneak peak? It’s something you’ve always fantasised about, and it’s not like this’ll be your first attempt, this’ll just be a little more direct.’ He tried to convince himself. Naturally it took him quite awhile to come back with a proper response, all too busy surveying his little sister’s body, and all the dirty scenarios he could possibly get himself into with it. ‘This is wrong, but I suppose a little fun couldn’t hurt. Twilly isn’t seriously injured, and she won’t remember a thing.’ He thought, coming into broad agreement with himself.

Shining then shifted into view behind his little sister’s rump, his erection getting noticeably more excited as he did so. And there it was, his sister’s perfect little marehood, tight, plump like the rest of her behind, and of course wet, not to mention the irresistible sent or heat it was giving, or the swollen little nub that lay at the bottom of her outer lips. The stallion practically drooled as he examined his little sister’s pussy all the closer, increasingly losing any willpower and sense of discretion he may have once had.

Instinctively Shining put his forehoof out to inspect the fertile young mare before him, lightly prodding at her vulva in search for any response. The mares outer lips were squishy and soft to the touch, indeed he imagined that they’d feel great wrapped around his cock, like a nice warm sleeping bag, only cock sized and reflexive to the touch. He continued to lightly prod at his sister’s marehood for what felt like hours, but was likely less than 5 minutes, all the while the little voice at the back of his head telling him how perverted he was acting became increasingly silent. Again, it’s not as if anypony, least of all twilight would ever know, it would be as if it never even happened, to everypony but him.

As these thoughts raced through the stallions head he became evermore adventurous, turning his light prodding into caressing and massaging, which went affectionately from the bottom of the mares sensitive little nub, up her puffy lips, all the way to her irresistibly tight anus, gaining a few quiet moans and the odd kick as a reward for his efforts.

After fully acclimatising himself to his sister’s private parts Shining pulled his forehoof back, his cock now painfully throbbing, begging to go down on the beautiful young mare before him. ‘Am I really doing this?’ He thought to himself. ‘Come on, you’ve already overstepped your line, there’s no harm in going a little further. Besides, no one will know.’ He replied to himself in an all too convincing voice. ‘Yeah, and hopefully this will help relieve some of my tension. If anything this will only be closure that’ll help me get over this perverted fetish of mine.’ His mind, twisted by unrelenting lust reasoned.

How does Shining choose to relieve his tension?

He eats her out followed by sensually fucking her newly clean marehood. (Slow, sensual)

He lubes up his cock with some shampoo before going in hard on his sister’s irresistibly tight ass. (Rough anal, short)
