“Gah, she’s such a tease!” Fumed an angry Twilight as she pounded her hoof against the wooden frame of her bed, only to recoil a moment later by the unexpected outburst of pain caused by smashing one hard object against another.

Rubbing at her sore hoof, Twilight looked around her empty bedroom with agitation. Now that Rainbow was gone, she found herself with a burning desire to spread her legs open; slowly forcing her newly acquired black toy into her quivering pussy, in hopes of calming the raging fire that her brashful friend ignited within her.

Twilight started to make her way toward the dresser, of which she kept a number of toys, including the big bad black dragon dildo of which her mind and soul currently desired.

After reaching into the drawer, she managed to find what she seeked within a short amount of time. This dildo was fairly large, coming in at just under eighteen inches, so it was logical for her to find it with little to no real effort.

Her mind trailed, and she envisioned herself being stretched to her very limits by the large dildo that was soon to be within her walls. The very thought of potentially being torn apart by something so large, so foreign, so monstrous, forced her pussy to wink in undying anticipation. She was wet, and could feel the heat rising up, engulfing her mind with perverted passion.

With the toy tightly held within her magical grasp, Twilight slowly returned to her empty bed, allowing her tail to swish lightly against her burning marehood with every swaying step. She moaned under her breath as the soft satin sheets rubbed up against her overly sensitive fur.

Once she was in a comfortable position, she spread her hind legs to the open air, and moved the toy to rest just before her glistening entrance, which was winking in sheer anticipation of what was to come.

Looking down at the sight before her, she realized just how large the black dildo truly was in comparison to her rather small and unused slit. The head of the artificial cock was nearly twice the size of her opening, and while this would discourage most normal mares, Twilight was certain that she could accommodate the invader. She was knowledgeable when it came to the anatomy of a mare. She was aware that her body would adjust, no matter how large the object, or penile intrusion.

With this knowledge in mind, she rubbed the head of the cock against her labia until the toy glistened with her natural lubrication, and proceeded to shove the toy into her in one quick movement, spreading her wide, and causing a moan to escape her.

With the head of the toy now firmly resting within her inner walls, she allowed for her inexperienced body to adjust to the large intruder. Every muscle squeezed at the object inside her, forcing tiny shivers of both pain and pleasure throughout her body.

Looking down through teary eyes of lust, Twilight noticed a slight bulge in her belly. With a free hoof, she reached for the bulge with idle fascination, and was instantly rewarded by the most pleasurable pain imaginable. While she wasn’t typically into S&M pain play, she couldn’t deny that the pain she felt increased the amount of pleasure. The simple act of touching the dildo through a thin layer of skin that separated her womb from the outside world caused her to jerk her head back in orgasm almost instantly. This added movement, and uncontrollable pulsating, forced her muscles to contract against the foreign object, increasing the feeling of being stretched to entirely new levels, once again forcing her over the top and into a second orgasm.

Her heart was pounding heavily, and her breathing was short and rapid. She felt the world slipping away as her vision blurred. She had never felt so much pain and pleasure, and she began to question if what she was doing was right. It almost felt criminal to be able to inflict so much pain and pleasure upon oneself, and it had gotten to the point where she could no longer tell the two apart. She loved the feeling of being stretched to her absolute physical limits. She felt dirty, like this was something she shouldn’t be doing… but she didn’t care.

Her mind and body were fighting over right and wrong. She knew what she was doing was morally unacceptable by society, but it just felt so darn good! How could she not do this to herself?

And just like that, she knew for certain what she had become. She knew she would continue to push her very limits until somepony forced her to stop, or until she found herself with more pain than pleasure. Yet, she didn’t care. She loved the idea of mixing pain with pleasure. She loved being filled to the brim. She loved seeing the bulge in her stomach. She loved…

“...being a whorse.”

Author's Note

I was going to take this chapter seriously at first, until I realized that I'm a horrible author that can't write clop to save my life.
So, I did what any failed author does when he can't write; I turned Twilight into a masochist.

Now, let the downvotes rain! This story deserves it...
