Twilight began to shift and moan under him, her body becoming all the more animated by the second, which was mostly ignored by the stallion above her who was far too enthralled within his little sister’s pussy to notice a thing. Upon finally noticing the reaction of the beautiful mare under her Shining only picked up the pace, his cum driven homing in on her moans of ‘approval,’ completely missing their implication.

After a few seconds of shifting about Twilight began to regain some of her consciousness, her mind still quite sore and groggy. ‘Huh, why does my head hurt so much?’ Twilight thought to herself as she rolled her head over to one side. ‘Hmm, it’s absolutely pounding. Wait! Since when was my head attached to my tail? How hard did I bang, Oh…!’ Twilight thought, interrupted by one specifically hard, and strangely pleasurable pound, as her ‘head’ began to throb harder.

‘Uhhh, what happened to my head, and why is starting to feel so good? hard, sore even, but strangely pleasurable.’ Twilight's dazed mind thought, trying desperately to fit the pieces together as her ‘head’ continued throb, feeling like it was being repeatedly pound by a strong, curiously hot jackhammer.

After a few seconds of gradually regaining consciousness Twilight’s mind slammed hard against a brick wall of realisation and her eyes shot open. Her head certainly didn’t feel great, but it was far from the hardest thing being pounded. In panic Twilight froze up, paralysed with shock and fear, her eyes staring directly forward, still and emotionless. There was a stallion under her tail, and a big stallion at that.

She simply lay there, still and unmoving, completely unsure of what to do or say next. On one hoof she could stay silent, hoping that her assailant would just finish and leave her be, on the other she hoped that simply asking him to stop would work, that somehow she had managed to bed a stallion and simply forget about it, and that this wasn’t what she thought it might be, that she wasn’t being ‘assaulted’ by a complete stranger in her own home. Her mind was made up for her as she lay there, and in complete disgust of the realisation hat in some dark primal part of herself she was beginning to enjoy her little hopefully not non-consensual affair, and the increasing fear of unwanted impregnation. Needless to say the type of stallion that would break into your house and knock you unconscious isn’t exactly the type to be fond of protection.

Gathering all her courage Twilight spoke, or rather whispered up, still paralysed with fear. “Who...who are you?” Twilight whispered, instantly regretting her decision.

Still in a haze of lust and sexual frustration Shining couldn’t help but get even more aroused when he should have been panicking. His mind washed in a deep fogg of his little sister’s powerful pheromones, the smell of a mare that wanted it. Keeping his pace Shining bent his head towards the mares ear, kissing just behind it before whispering sensually. “I don’t think you’d want to know that, but then again, maybe you would.” Shining said lustfully, as he picked up the pace of his deep thrusts, his heavy balls now audibly pounding against the mares backside.

Twilight’s eyes began to water, even more confused than before. By the tone of his voice she could tell that the stallion above her wasn’t going to budge, and there was no way that her weak body was going to move his strong athletic frame. But she couldn’t believe that this was him, this couldn’t be him, her BBBFF. That’s what really got to her, even the idea that he could even think of doing something like this traumatised her. This couldn’t be him, this had to be some kind of sick joke, her big brother would never dream of violating a mare, least of all her, his little sister. Looking up at the stallion above her Twilight’s eyes ran heavy. There he was, powerful chest, strong jawline, with a flowing blue mane and a pristine white coat, she couldn’t doubt the evidence before her eyes, but she had too, he loved her, he wouldn’t do this.

She hesitated as she opened her mouth to reask her question, but she couldn’t form the words. This was him, she didn’t know how or why, but she couldn’t deny it, no matter how much it hurt her. Her big brother was a good 14 inches deep into her tight marehood, his thick shaft pulsating and throbbing as her vaginal walls naturally lubricated and massaged it, her big brother was having his way with her, her Shiny was unrelentingly assaulting her and it didn’t look like he was going to stop.

Once again finding whatever shattered fragments of courage she had left, Twilight leaded with him. “Please, please tell me that this is some kind of misunderstanding. You have to get off of me now! Please, oh Celestia please just get off!” Twilight screamed in near hysteria, tears pouring down her cheeks as her body was rocked by her big brother’s powerful thrusts.

He hated to admit it, but he couldn’t deny how honry his little sister’s pleas for mercy increasingly made him, how hot the sound of her tears running down her delicate little face was. He grabbed ahold of her flank with his hoof, moaning loudly as he once again increased the speed of his thrusts, leaving his swollen balls quite sore as they rammed relentlessly against his little sister’s backside. “Sshh, Twily, it’s going okay….I’m just giving you a ‘deep cleaning.’ Uh yes….hmmng. somepony had to finish cleaning you off.” Shining said, moaning and panting roughly as he did so, blindly ramming into his little sister’s marehood, losing all coordination in his lust, as he continued to ravage her pussy.

With tears still running down her face Twilight began to scream hysterically, thrashing about under her big brother’s strong frame, failing pathetically to escape. Pinned down at one end by his powerful hooves, and the other by the sheer length and weight of her big brother’s thick cock. “Why…..why are you doing this to me? Please….S….Sh….Shining, you, you have to get off of me! I’m sorry, I’m so, so sorry! She screamed in panic, struggling to voice his name, as her mind still desperately doubted that this could be him.

Shining merely puffed and panted, biting down lightly on his little sister’s ear before whispering back into it. “Because I need you Twilly, I need my little sister’s tight pussyl! I have to breed her wonderful marehood, I need to be inside of her, I need to lay my hot seed in her hungry womb! Oh Twilly, if you knew of how I dreamt of breeding, of filling that tight little snatch of yours with my thick cock, coating your insides my seed, with your big brother’s seed!” He ranted, the only other sounds coming out of him being the occasional moan to emphasise his point, as his heavy balls, swollen painfully with oceans worth of his thick seed slammed loudly against her bruised rump.

Twilight let out several painful moans before desperately trying to plead with her brother once more, terrified by the prospect of what he was saying, of what he was demanding. “No, Shiny, please, you can’t do this! You’re, oh Celestia, you’re going to get my pregnant! I’ve never even been with a stallion before, you can’t, this can’t happen to me! You’re my big brother for Celestia’s sake! This is wrong! Please, please, just stop! I promise I won’t tell mum or dad! Just stop!!! You’re my big brother!” Twilight scream out desperately, full waterfalls of tears streaming out of the poor mares eyes as she lay there under his weight, shaking and terrified.

With each word Shining felt his cock grow tighter, as his flare grew in weight and size, making harder, both physically and physiologically, as every instinct within him screamed at him to bury himself, his stallionhood, his seed deep within his little sister’s womb. Shining’s cock throbbed hard as he felt his heavy balls relieve themselves, sending hot waves of the stallion’s thick seed through his cock and deep within his little sister’s womb, his cum painting the insides of the mare white. Moaning deeply, Shining wasn’t as surprised as one might think as he noticed his little sister’s own fluids wash over his stiff member, reaching her own climax involuntary right after her big brother’s.

What happened next?

Twilight passed out again after reaching her climax. (Short ending)

Shining rolls Twilight over, makes out with her, and then forces her to suck on his half erect member. (Open mouth kissing, blowjob)
