Marco continued to look through the book. Although there were so many possibilities for things to try, he kept hunting for the spell that would bring his dick back
into proportion with the rest of his massive body. Then he saw it, and read it aloud:
Thy member's size may be increas'd
Just make the donkey your ideal
To accept that form of beast
Bray and you shall find it's real.
Nothing happened, so he read it out loud again. Still nothing, but then he thought, maybe this spell is THAT literal. Maybe I need to **bray like a donkey**.
Feeling somewhat foolish, he said "Heehaw" softly... and immediately felt a quiver in his groin. "Heehaw," again, this time a bit louder... and his dick twitched and
stirred. "Heehaw," firmly and loudly, and no question this time; he could feel that he was both thicker and longer. He looked down at himself and smiled. "Fucking
heeHAWsome!" he shouted. He was BIG. But still not big enough...
"Heehaw! Heehaw! Heehaw!" and NOW he was getting somewhere! Larger and larger he grew... He closed his eyes, revelling in the bliss of the exquisite
sensations, blissfully oblivious to the other changes taking place. The skin of his dick started to grow darker, and his foreskin began to grow larger, and then plied
itself to his abdomen. In short order, his dick rode in a sheath.
And if his clothes had not already been shredded, he would have felt the friction as a donkey tail emerged at the base of his spine. As is, he thought nothing of it; it
seemed perfectly natural as it grew larger and hung behind him, twitching and swinging gently.
He opened his eyes, and looked for a mirror to admire his new, improved form. He caught his reflection, but it was not quite all that he expected. (Or, more
accurately, it was more than he had expected.) "Whaaa...HAW! EEhaw! Heehaw!" he exclaimed. With the brays, his ears twitched and swivelled on their bases,
as they had started to become pointed, furry and elongated. With each additional bray, they became taller.
"What the EEHAW is going on here?!?" Marco exclaimed. He took another look at the book, and re-read the spell (generally something most usefully done
BEFORE invoking it). Then the realization set in: the donkey's form he had accepted was not just limited to the size of his dick. Desperately, Marco started looking
through the book for a counterspell with hands that seemed clumsier and more cramped than a few minutes ago. And then...
"AhaHEEHAW! he exclaimed, and his ears grew again. "I don't have to be a donKEYHAW! Heehaw!" and the hair on the top of his head started to look more
like a spiky mane, and grew down the back of his neck. He realized that he would have to invoke the counterspell soon, or he might not be able to. Even now, it
was ever more difficult to talk without braying, and with every bray, he took on more and more of the donkey's form. And who knows what effect braying during a
counterspell might have?
And as his hand (with fingers grown strangely stubby) wandered to his groin and he marvelled at what he found there, he wondered if he really wanted to read the
counterspell after all...
