Marvin soon found himself tucked away in a room which lacked much of the luxury he'd had inside the main house. His lack of such luxury was not his most pressing concern, for now he was becoming a valued part of Sunrise Research Farm.
A holding cell just 12 x 12 made of poured concrete in walls, floor, and ceiling. His only luxury that made this concrete stall something a little more habitable was a steel frame, and plank board bed. His only other item which functioned as a toilet, was a round drain set in the center of his cell.
The joyful feelings of acceptence in the workplace was dwaining fast. He sat there stock naked his changing body in total view by all. It was less comfortable to be seated as a man might, his large piggy' balls jutting out past rounding out buttocks. His tail too would often become caught by the slats making his bed. Instult and injury he had only to sit and fondle his changing maleness, feeling his bulk growing over what was a human body.
It was for Marv the touching of his meaty sheath which began to bring on erotic waves of sensual sensation. Not long after he was in his cell did he begin to rub himself making an odd looking red shaft inch its way out into the light. Bit by bit and with each time he coaxed the organ out it was changing and becoming more typical that of a Berkshire boar. Pointed and tapering down to the base it had ridges making it look like a corkscrew.
Marvin's ridges made his sexual desire ruffle up and bring on strange bestial demanding waves of passion to mate in animal style.
It was well near the next morning when Marv having not slept the entire night was seen practice humping his shaft into the air. He was then making bestial sounds, grunting with hog like vocal cords and a mouth which by then was as if he'd been born a hog.
Caught in mid stride as he humped his thirty third imaginary sow, a guard opened his cell door. In a quick move the man set inside a five gallon bucket of soupy hash. Greens galore, soggy bread, and from the smell a fair amount of goat's milk which made the morning's brew.
Passion for sows ceased only long enough for Marv to dip his head into the bucket and slurp, chew, and drink the slurry.
A return to practice which makes one perfect as Marv continued wanting relief from his maddening sexual lust. His was a morning breakfast of unique body building and enhancing protiens made up to help his body gain muscle and mass.
So his time and day went onward, lunch was the same as breakfast, and dinner the same again. every four hour through the entire night he was given yet more buckets of the slurry. Days passed and Marvin was rapidly being merged into animal tissue and his human self being lost within a beastly body.
The afternoon of his eleventh day had the Professor coming to greet Marvin in his cell. As the door to the cell opened Marvin strained to look upward from his four legged stance. Cloven trotters now were his feet. Bristles covered his thick hide. A face only a sow could love was now what Marvin saw the world and they looked on him.
Oinks, squeals, and grunting, Marvin moved in primal circles about his cell. Small heeps of piggy stuff littered his cell, the stench was how it smelled to the guards, but for Marv the stuff reminded him of his home.
"I congratulate Marvin our new sire boar now ready to go to work and build us a fine herd!" said the Professor as if showing his gratitude for a job and change well done.
True hog sounds echoed the hallway as a guard armed with a cattle prod urged a six hundred and forty pound boar along to meet his friends. Marv went willingly but the closer he came to the open pens his meaty cock drooped out and skidded along the cement.
