Your father was rumored to have become cursed to become a fierce 8 feet high werelynx with claws that could rip through flesh, fangs that could tear apart bone, and an overwhelming sense of smell that could detect blood from miles away. Your mother on the other hand became a fox-like creature with long white hair that she kept tied behind her head, sharp ears that pointed forward, and amber colored eyes that seemed to glow in the darkness. She also possessed incredible strength, agility, and speed which made her seem almost inhumanly beautiful.
But most importantly, both your parents had been marked with a witch's curse. Unlike many others who simply became mindless carnal beasts, unable to do anything but submit to their waning desires. Your family was cursed with forms that changed genders according to their fucker's whims. Your mother was cursed to watch as men came and took pleasure in her husband for hours upon end, while he struggled against his urges, alternating between man, shebeast, and herm, until finally giving up and succumbing to their lustful cravings... While she herself found herself sprouting cocks and becoming aroused whenever someone looked at her, no matter how much time passed since they last saw eachother. And your father was cursed to feel their body modify it's sexual form of whatever beast pleased them best, whether it was a horse cock, a wolf knot, or a veiny hybrid knotted pucker.
But far from being received as a blessing... the witch had full control over artificially induced heats and lusts and was able to use this power to force people to do things based on those feelings. If you disobeyed her commands, you'd find yourself transformed into whatever animal you displeased her with next. So basically, she could turn you into any animal you disrespected her with, and make you obey her every whim!
But that wasn't all, transforming so much caused latent hormones to continue triggering somewhat permanent transformations or form locks, making you either grow bigger than normal, gain more muscle mass, get longer legs, larger breasts, or even lose fat and become taller, thinner, stronger, faster, etcetera.
As a result, everyone knew better than to cross the witch. Everyone feared her. But that fear was justified. It was seen as better to be cursed to become a powerful sexpet than be cursed to become a newt, So your family tolerated it. Though sometimes they wondered if it was really out of ill or good will...
After all, you still had your life on your side, but all this over your parents once picking a basket of strawberries from a witch's garden. It seemed a bizarre explanation, but at least it beat the tales you heard next door of someone who was cursed into a beast for refusing to buy a overpriced rose. Or the tale where a girl refused to give her lover a kiss because she thought she might catch a cold, and ended up turning into a frog.
It was enough to drive anyone mad.
And yet despite everything, there was nothing you could do to change your fate. They say the curse awoke on your 18th birthday and would only just get stronger since. Every day now, you began to notice changes within your own body. A little bit of fur growing here, a few extra pounds added there. Your waistline started expanding, and soon after, your hips. As well as the size of your breasts. At first you tried to keep it hidden under loose clothing, but eventually you gave in and accepted that you wouldn't be able to hide it forever. You had to accept the truth, and live with it. No matter how hard it may be to bear...
