"Awwwww, come on, pleeeeeease?"
"No."
"Just one little sip?"
"No; it's not ready yet."

That riveting conversation took place in my living room; amidst a bubbling mini-alchemy set and some random TV show going on in the background.  Myself; a large, green & feral Tyranitar sat on a couch whilst Seindrache, my curious blue dragon friend (and test subject) curiously sniffed and toyed with the carefully calibrated artifacts on the table.  I was working on a little side project - a potion that would instill the imbiber with youthfulness.  A simple mixture, but it took a long time to brew!  Upwards of eight hours had gone by by now, and the dragon; albeit cute, was getting impatient.

"It smells good!"
"That it does, Sein."
"Like... cherry?"
"That's just the flavoring.  It would taste like ass should you drink it straight right now."

In truth, I was waiting for the mixture to turn a very specific shade of green.  Right now it was orange, but the chemicals needed at least another hour or so to finish up.  I planned to have Sein drink the whole beakerful - two cups of the stuff!  I didn't know how well shi'd receive it, but that's part of being an alchemist~  In the meanwhile, Sein's butt looked pretty inviting as shi leaned over the living room's coffee table; a welcome distraction from monitoring the heat on the hot plate making the mix steam a little bit.

"Hey Sein; do you wanna keep my lap warm while this keeps brewing?"
"Yes I do; but may I?"
"Of course~"

I couldn't say no; Sein did make for a good lap warmer since I was a little chilly sitting all by my lonesome.  The blue dragon scooted from the side of the couch and plopped hir butt right between my legs and nestled in.  Shi was warm, cuddly, and rather big; but I had plans to change at least one of those things by the end of the day.  

"What's in this beaker, anyway? "
"A mixture of Koolaid and some water."
"Sounds tasty!"

The stand finally finished brewing up what I'd been concocting; a deep, vivid shade of green clouded the beaker, and I quickly removed it from its heat as well.  (Google's great for getting things jumpstarted like this.)  The mixture steamed for a little bit while Sein used hir butt to keep my lap warm.  Shi was a keen little dragon, wearing a frilly black and white dress adorned with a couple bows on hir horns, arms and tail.  Shi also wore some dark pantyhose that hugged the curves of hir legs as well; a proper maid shi made!  Up until now, the dragon had just been helping around the house - cleaning up dishes after mealtime, vacuuming up, dusting off the TV; typical maid duties.  Shi loved it, and I loved the upskirt shots from time to time.  Ah, memories.  I'm digressing though; the matter at hand was to get Sein to test my newly brewed drink!  It was getting to the perfect temperature, so I asked hir to grab a couple of teacups to pour it into.  Shi sauntered into the attached kitchen, worming her way through the tall china cabinet and grabbing two very adorable pink-enameled teacups to use, along with a set of red fabric placemats, matching teacup dishes and a set of spoons as well.  With a pair of tongs, I removed a small stirring rod that lay at the bottom of the dark liquid (it's a choking hazard; not for children under 12) and set it aside.  The liquid was a little less viscous than Jello, but not quite as thick as molasses; for comparison.  It smelled sweet, despite basically being cooked for half a day!  I poured Sein's cup carefully as shi went to sit at the opposite side of the coffee table; taking a little pillow to kneel on the floor with.

"Oh; I forgot!  You just wanted normal tea, Vector~"
"Uh, yeah?  I'm not drinking this right now; at least not the first batch!  That's YOUR job!"
"Heehee~ Okay, one moment."

Sein made some bangin' good iced tea the other day, so I asked hir to make a whole pitcher of the stuff.  Shi went to grab it out of the fridge and returned to me, pouring out a cupful of the stuff before setting the pitcher onto the table.  As we prepared to drink our respective 'teas', I teased Sein a little that hir cleavage was showing.  It was kind of hard not to; what with her D-sized boobs and all.  The blue dragon looked a little surprised, but it wasn't anything out of the ordinary!  Shi started to drink hir 'tea' shortly afterward.

"Hey, this turned out pretty good!  Tastes sorta like... apple juice~"
"Good; I'm glad it turned out like that.  You should only need a -"

Sein suddenly BELCHED something fierce as I only closed my eyes for a second to revel in the fact that I did something right for once!  Shi'd drained the beaker and teacup before I could even finish my sentence, hiccupping once and giggling to hirself.  The blue dragon wiped her lips politely with a napkin afterward, apologizing profusely for being so rude.  (Even though I didn't mind it at all; shi had quite the tummy capacity to drink roughly four cupfuls of syrup in a handful of seconds~) The dragon herm suddenly went wide eyed with a big smile creeping over hir face.  Sein curled hir toes a little bit and felt hir tummy gurgling as it slowly began to digest the youthful potion inside hir belly.  It wasn't a very loud gurgle, but it'd easily turn up on some audio recorder if it was the only thing going in the room at the time!  I just sat and watched as the potion quickly got to work on the girl's brain.  
The blue and green-haired dragon started to drool as she looked around the room.  In hir head, things quickly took on a much more simplistic, childish view.  Shi rocked on hir tush a couple times while her thumb inadvertently began to gravitate towards hir muzzle, rocking just a bit too hard and falling back onto hir feathery white wings!  I thought it was hilarious, but simultaneously I was concerned - the recipe only called to drink one cup at a time, and Sein drank four... the blue dragon then in short order began to shrink in height, gaining weight instead!  The poor big dragon was quickly becoming a very little, fat one instead!  Sein burped again as shi started looking more like a blob in those clothes; not very ladylike anymore, but more babylike by the second.

"Feeeeeeed meeeeee--!"
"You're hungry?"
"Feeeeeed me."
"Okay okay.  First though, we need to get you out of those clothes before you ruin them -"

Sein idly suckled on hir thumb and twisted hir horn with her free left hand as the potion continued to work, removing hir continence rather quickly.  The dragon started emitting a number of wet, gassy blasts from the opposite end now, as well as a lot of grimy, greasy sweat as hir body began to overheat, too.  I couldn't have hir shitting on the carpet; I didn't wanna have to do work it all out again later!  I picked up the three-foot, five-hundred-pound reptile with a good bit of effort and carried hir upstairs to the nursery room in my house.  
Unfortunately, hir dress was fairly difficult to get off since hir curves and such were much more... bulbous by now.  I sat hir on a changing table and looked through some of the clothes I had that might fit - a little black and white polka dot leotard with frilly pink adornments caught my eye.  (I personally didn't wear it; someone got me it as a gift a while ago, but a feral Tyranitar in that? No way.)  It was big enough to carry the proportions of the large dragon girl on the table, and I even had some matching diapers left!  (They were also a gift; don't judge me!)  I walked the dress back over to the blubbery dragon that was keen on sucking that thumb raw; so a single pacifier took its place in short order after I padded the poor girl up and got the dressy garment over hir body.

"That's better.  NOW we can have lunch.  What do you want?"
"FOOD."

Sein was very good at articulating what shi wanted to eat, and as little as shi was, all I could think of was baby food!  Y'know; the kind they keep in cans and such; maybe some formula to go with it too.  (I may have prepared a little bit too well for such a thing; the tutorial on Google said you should probably prepare for a big cleanup...)  Either way, I did get the big fatty back downstairs and into the kitchen, sitting hir tush and tail on the kitchen's marble island for a bit while I set up a high chair for hir to sit in.  I spun back around and set hir in the metal-barred chair,  making it creak a little bit under the dragon's weight.  It held hir weight (for now) while I turned to the cupboards for some food jars.  Sein apparently couldn't wait to put on some more weight, and as such the next fart shi released gave off a much stronger odor; making a rather stinky present inside that lifted hir tush out of the chair at least an inch or two!

"Sein, you're supposed to go potty AFTER you eat..."
"NUH."
"Hmph.  Well, you better eat all your bananas then since you're SOOOOOO hungry..."

I teased the blue dragon as the familiar *crack* of a food jar opening made hir eyes light up!  Shi opened hir craw wide to a silver, plastic-coated spoon I dipped into the jar - jar-sized spoon, that is.  In one quick chomp, Sein closed hir lips over the spoon, drawing back and swallowing the whole jar's contents at once!  Shi ate so fast shi didn't notice that hir weenus was starting to prick the front of hir padding and let loose a subtle hiss into it, and I couldn't help but stifle a giggle while the dragon demanded more food.  The potion coursing through hir system made hir digest that jar of mushy bananas extremely quickly; ten ounces of fruit became ten pounds of fat!  The dragon's folds grew thicker and thicker while jar after jar of cherries, applesauce and other assorted baby food went directly to thighs, gut and boobs (shi still had those!)  I think she went through about thirty or so jars before the chair finally gave way and thunked on the floor backwards, sending the poopy baby girl reeling out of the kitchen and backwards into the living room.  Shi thudded against the coffee table, seemingly unhurt due to all the blubber protecting hir tush from harm (in addition to the stretchy, feral-sized diaper holding all hir dookie in tight against hir butt)!

"Dwaggie full.  Mmmh..."
"Already?  But you didn't have your milk yet!"
"Dwaggie full.  No want milky."
"Trust me Sein; you're gonna want milky when that potion wears off..."

Foreshadowing aside, I'd been in the kitchen preparing a special formula mix (again, provided by the good folks at Google) that would help the dragon back to normalcy.  At least with time it should; this was like some of those herbal remedies that you could find online that aren't always 100% effective.  I just needed the powder, some water and a blender to whirr it up into a bottle to feed the constantly-dookying dragon in the living room.  I'd give hir a change later; all this hard work was tiring me out.  A few minutes later after blending it up, I brought the blue-colored plastic bottle over to hir in the living room.  I needed all my strength to heft the dragon back up onto the couch into my lap again, so the bottle sat on the coffee table while I did that.  With the blue dragon securely in my lap again, NOW I could feed the poor beast; simultaneously stopping hir from pottying as easily!  I didn't necessarily wanna with hir stinky butt as close to my crotch as shi was, but I knew in that primitive mind of hirs, shi was somehow gonna get off to it.  

Sein reclined into my chest while I tilted the bottle upwards, and hir farting grew less intense as the stool hardener in the formula instantly began to counteract the potion from earlier.  In fact; I could feel it working as it felt more bulgy when shi tried to push; harder still, like a fiber-rich log again after a couple more poots!  The bottle wasn't even half empty yet, and I could feel hir starting to get a bit lighter with time in my lap. She cooed and thought happy thoughts while the formula continued to work throughout hir body, molding the turd steaming out of hir butt into a big, fat poopy buttplug as it struggled to exit hir bowels!  The food in hir gut continued to digest like 'normal', adding to the load slowly but surely.  I just giggled while shi made a couple faces and strained to dump, but sitting down and pooping isn't the best position to do it in!  Hir formula finished draining out of the bottle, and that turd was gonna be lodged in there for a while.  Besides, I still had one more thing to do with my new little 'pet' - get hir to spooge.

The pervert in me took over immediately as I dug my green claw into the front of hir dress, making the blue dragon squeak all of a sudden!  The squeaking turned into moaning as I went in deeper, pushing around hir right side and mashing the mess around in hir diaper a little bit to make hir butthole feel a little less trapped in there.  I could feel hir dong throbbing intently as shi began to pant, and I took it one step further, hefting the heavy dragon up onto my leg and bounce-squishing hir loaf on it!  That did it 100% - the dragon screeched a little bit and held onto it while shi ground hir poopy butt against the meaty part of my leg!  I just snickered while shi rode out thirty seconds of bliss and collapsed against my chest again, stinking fiercely now as the plug stayed firm and would stay firm until all that fat turned it soft again!  The formula made hir digest the beefiness as the potion continued to wear thin on strength, and the fattening effects started to wear off too.  The smell of dragon dookie didn't go away, though; as Sein grew back to hir normal proportions; packed full of digested fatty poop and a big, fat plug keeping hir five-foot-four tush nice and packed (until I decided to pull it out, that is!).

"Ugh... Vec...?"
"Yeah, Sein?"
"Why am I sitting in your poop?  *sniff*"
"Wasn't me, stinky girl.~"
"Oh."

Sein giggled a little bit as the diaper and clothes had gotten rather big around hir more light, lithe form; sitting halfway in a pile of hir own shit!  I just chuckled as shi suddenly spun around and planted hir dirty paws on my chest; a mushy load in the dragon's paws trailing upward to my own craw shortly after.  I didn't have a choice; the horny dragon was gonna make me eat something too, apparently (not that I'd mind)!  I swallowed the pawfuls of poop that Sein shoved in my green-brown mouth before shi leaned up and smooched me right on the lips.  We shared a little kiss as I had a spot of an orgasm as well (albeit hidden within my crotch pocket; but hey, an orgasm's an orgasm in my book~

"You should eat the rest of it too, Veccy~  It felt good being a fat baby for a while..."
"Maybe later, stinker.  We should get you cleaned up."

Sein shook hir head and pulled up from under the couch a collar I'd never seen before - it was leather-bound and laced with a hot pink feathery ring around both sides of it.  Shi flicked it up and over hir head, bonking off my chest and resting between hir boobies.

"How about we do this instead?  I'll be your pet for a while and you can whip up more 'formula' for me later... 'Master'."

I couldn't resist.
