(Author's note : That idea of mine has been improved upon by Burst Jammer who made an alternate version of my chapter. Other than enhancing the transformations' descriptions, he has also modified the rule I had made that the duration of the transformation shall be left to the appreciation of the teachers or parents, for a duration of three weeks. Though his version of the story had a wider success than mine, I would like to have an equivalent for this version of the rule and as such, I'll be pasting the chapters he made for his version here.
Thus the merit for those chapters, should they be read is not mine to take.)
As the tingling feeling intensified throughout his body, almost feeling sensual, Edwin felt small hairs growing all over his body. Looking down at his arms, he was shocked to see the fur rapidly coming out, forming a black and white spotted pattern. He DID want to transform on his trip, but was he really willing to turn into a cow?
"Well, well, look at that!" Ms. Santos said cheerfully, as Edwin's body began to take on more body mass, especially around his waist and rear. "It looks like we're going to have another dairy cow, now won't we class?"
Realizing what would've had to happen for him to become a dairy cow, Edwin wanted to say something, a protest of sorts, but began to grow fixated with his latest changes, his hands and feet beginning to harden and fuse together, creating black hooves. Soon, his entire body was covered with fur, as he kept gaining weight.
"Wait, Mooooooo-" Edwin tried to say, before a deep lowing voice came out of his mouth, causing him to blush with embarrassment.
"Uh, uh, uh, no complaining Edwin!" Ms. Santos chided, shaking her finger gently. "You're going to make a fabulous dairy cow, just you wait and see!"
And the changes continued, the mass that Edwin was gaining seemed to be focusing particularly in one area, however, just above his groin. Edwin attempted to take off his shirt, but there was no need, as a large pink fleshy mass suddenly burst through, effectively shredding his clothes. It began to fill up with a white substance, filling Edwin up with pleasure. He let out a subconscious moo, his voice growing more feminine and sultry, as he was forced onto his knees, a tail sprouting from his enlarged ass.
His mouth began to push out, turning pink in color as a muzzle formed in front of his face, his nostrils enlarging as did his ears. Next the changes moved for his already erect manhood, a soft tugging causing it to recede into his body. Edwin began to panic at this, letting out distressed moos, but the process continued. What was a gentle tug quickly escalated into a strong pulling sensation on his penis. He couldn’t contain his feelings as his groin was pulled in torturously slow. It inverted with a wet POP and she had her first female orgasm as her new vagina finished forming.
The process was done, as Edwin looked her new body over. Ms. Santos, holding a cowbell, walked over to the new bovine, attaching the bell around her neck.
"That bell contains your name for the time being, okay?" Ms. Santos said, leading Edwin to the other cows, who were currently being watched by a farmer.
The farmer grinned as Edwin walked into the group, slapping her ass, causing her to let out a startled moo. "Well, well, welcome ladies." He said, grinning. "Name's Johnson and I'll be your caretaker for this little trip! First, let's get you to the stables, shall we?"
