Choose Your Own Adventure Sparklecest

It was high spring and Twilight Sparkle lay in bed, shaking with sickness. Her head was throbbing, she was covered in sweat, and her marehood felt at least as hot as Celestia’s rising sun, if not hotter. She was in the middle of a particularly strong heat, and it was completely unbearable. She had been through estrus many times since her fillyhood, but this was far more intense. Countless mares had warned that the longer she held out without a stallion the worse her heat would get, with the implication being that she should meet up with a young buck as soon as possible, to avert the worst. She had even heard a few horror stories of mares who held out for one too many years and literally died of heat, she had once discounted such rumours as hyperbolic exaggerations, now facing it herself she had no trouble believing such stories.

Her whole marehood was puffy and swollen, emitting a strong heat that could rival the fires Tartarus, not to mention the smell of a young fertile mare in the height of her season that wafted out from her enlarged folds. She had also heard a few rumours, and to her slight embarrassment, read a few erotic novels about heat-crazed mares tackling stallions in broad daylight and mounting their stiff members for everypony to see, or young bucks driven to insanity by the smell of so many young fertile mares, and simarly mounting the first pice of fresh meat they came across, these she had discounted as silly (but undoubtedly exciting) fantasies, dreamt up by heat riddled mares, but once again, she began to rethink that assumption.
