Transforming Commission

Author shifts into the fat bunny character in a story he was commissioned to wright each time he takes a break to fap to the story he's writing. A: is what's happening to the author, S: is the story he's writing

A: Intro, took anon commission, scene seems oddly arousing
S: Fat bunny at club, enjoying music, thin folf catches his eye, they dance some, grinding is involved
A: Author has confused boner but is used to it. Sneaks off to bathroom to fap, roommate didn't notice, authors toned belly gets pudgy
S: Bunny led upstairs to private room, candles are lit, suddenly feeling submissive, Folf orders him to strip, slowly, bunny undoes his shirt, Folf stops him, nuzzling the bunny's ears and fondling the rabbit's moobs
A: Author moans softly, pudge packing on, almost 100lbs heavier, stroking his cock, questioning why this turns him on. When done, tries to redo his pants but they don't fit so well so he doesn't bother. His tail has formed, and some fuzz on his body.
S: Bunny is now naked and collared, starts to lick the folf's sack, subscene ends at taste of the cock
A: Feet sell out to paws, ears stretch up. Body continues to swell, chair creaking somewhat. He's stopped worrying about roommate catching him, he's bout some 300lbs
S: Bunny gives a blowjob, there is tugging and rubbing of the ears (snesitve) pulls out for the money shot, bunny is completely subby
A: Needs whines, full 400lbs growth, muzzle forms, panting, rubs his neck like there's smoething missing and an odd feeling from under his rump, wiggling his tail
S: Bunny is mounted and properly bred by the folf, who claims him as his
A: Fully the fat bunny, whining nd unable to get himself off again, it really does feel like there's something missing from his needy rump, a fuzzy arm is pulled across his chest and neck as he feels a collar put on, turns and races his roomate - now master folf, who pulls him onto the bed and fucks the author hard, the cock inthe rump the missing feeling. 

Last line: Roommate says "That was the best commission ever."
