You swallowed the jellybean, and the flavour of peaches filled your mouth, followed by a bite of cinnamon and an odd coffee aftertaste. After rejoining your friends and buying a few more jellybeans, including two Brown-AB and two Red-SH, you went home, unknowingly making your changes permanent.
----------------------------------------------------------
When you got home, your girlfriend Kelsey was sitting on the couch. You held up the small bag. "I brought some weird jellybeans! Wanna try them together?" Kelsey, with her sweet tooth, gladly obliged.
The first jellybean was an odd shade of grey. It tasted like leafy greens, followed by an overwhelming sourness. Little did you know, it held back the changes for the two of you until intense pleasure.
The next was a deep maroon, with a flavour like pennies. Then a brown one that tasted like avocado and plums, and a yellowish white that tasted like cough syrup and pickles. You kept trying until you'd eaten the rest of them. Kelsey preferred the silver one that tasted like candy and an unexplainable flavour she described as 'like stardust'. You enjoyed the brown one.

Later that night...
Kelsey moaned as you drove your cock into her soaking pussy, as it clenched tightly around your stiff rod. You groaned as she kneaded your length. "Oh god, Tyler, your dick feels so good... I'm gonna..."
She was interrupted by her own scream as she came, and with one final thrust you climaxed deep inside her. You didn't shoot cum like normal, but instead, small growths begin filling her womb as they traveled out of your cock. You both came for many long minutes as the eggs poured from your cock.
Then, as your dual climax finally ended, you began to change. Your bodies changed to those of wolves, with great wings on your back. Your fur was white and hers was black. You were rippling with muscle, and determined the two of you were dire wolves, and didn't fully realize your changes in the afterglow of your orgasm. A slit formed on you, and your penis pulled back into a sheath which pulled back further into a small pocket, which Kelsey now had. Your fangs were long and pointed, and you both had striking violet eyes. Kelsey's pussy was full of your eggs, and soon more hermaphroditic direwolves would roam the town. You had a thought, and tried changing back to human. Your human form now had white hair, purple eyes, and fangs, and both of your parts, with a sheath and pocket for your cock. Kelsey's human form now had black hair, her own purple eyes and fangs, and yes, her new cock. Exchanging silent commands, the both of you left to transform the town.
