Since the transformation scenes were so popular, I'm going to do ONE more. This time, it's specifically the BOOBIES! That's right you lactose-thirsty loons, BREAST EXPANSION!

"Whoopsie! I Was just waiting in line at the bank and my GIANT TITS began to GROW!" BREAST EXPANSION!

"How am I supposed to reach the steering wheel?" BREAST EXPANSION!

"This recipe calls for several gallons of milk?! Where will I get it all from?" BREAST EXPANSION!!!

Rules are simple. 1 idea per person. ONLY Milky Way Spacers and Milky Way Spacer PLUS members can submit ideas, and ONLY they will see the fully finished art at the end of the month.

Character Rules: 2 character max if you are suggesting a single pinup image. If your idea has multiple stages of growth, like the Transformation scenes from March, then keep it to ONE character.

No outside links. Submit your ideas by Wednesday of next week.

Ess as a warlock sucking on Penny's breasts, that look a tad bit bigger than usual. She sitting on Ess's lap. Milk overflowing everywhere, all over Ess's face, falling to the floor, flooding the room. Penny is suspicious about her breast size and thinks Ess's obsession with black magic and the occult gave her powers to make changes on all aspects of the physical world. Ess is denying it, with a mouthful of creamy milk, the Penny brand.

How about a page from Karmagik's Thrills of Victory #4. The drones that were made by Dr. Purvis bimboifie two women that have hyper lactate syndrome. What happens when two lactating women become bimbos?

Almalu breasts suddenly grew and she needs Pumpkins help! Pumpkin needs to suck the excess milk from her breasts before AlmaLu's breasts crush her petite body!

Let’s go nuts Penny’s Mom has finally found the time to come visit her daughter. She’s all happy and completely oblivious her breasts are ballooning to a size bigger than Penny’s already swollen breasts Penny asks her Mom, did she drink from the red milk carton in the fridge or the blue carton and Mom says, “I drank both of them, why?” And Penny goes, “oh, no reason.” As Mom’s boobs keep growing and gallons of milk are now pouring out.

A mysterious illness has swept through Medowlyn farm: The swelling sickness! The only symptom is an intense swelling of the mammaries . AlmaLu doesn't seem to fit through doors now, and it's hit Heifelia even harder...

Karmagik

Aunt Sharon is standing out the top of a sun roof, flashing her breasts to everyone, when suddenly her boobs start to grow so large that she can't fit back inside.

Curiousonlooker

Before i make my suggestion, does the comic you posted happen before or after her most recent canon growth?

Personally I love the idea that milk is needed for waffles or pancakes and that's when things get out of hand. 💜

Veronica Stevens, still stranded on the Planet of the Amazons, has been taken in by the tribe that found her. While on a trek through the jungle to learn about her new home, Veronica gets stung by the thorn of an odd plant. What she wasn't expecting was for the plant's toxin to cause a sensation of drunken pleasure... and localized swelling. Her bust grows to Amazonian proportion, making her just as big up top as the giant busty ladies that occupy this strange world. [Lore: young Amazon women sometimes seek out this plant for its euphoric chemical properties - and for its semi-permanent figure boost.] Veronica's experience bestows her with absolutely titanic titties - and when the swelling eventually comes down, maybe she's left a little bustier than before?

Adventuress puts on magic amulet she found, and discovers it's the cursed Cowgirl Amulet, turning her into a silly, busty hucow.

Connie Edogawa

a cow girl of your choice (either a character you already have, or a new design, as you see fit) is holding her already rather large breasts, milk streaming slightly from her nipples as she bemoans (or be-moo-ns if you will) that she needs to be drained, but there's no one around. she happens upon an abandoned machine that appears to have a collection tank hooked up to hoses that end in cups that can stretch to fit over her breasts, with a large, dusty sign on the machine reading "Professor Lactatia's DE- *conspicuous space covered by dust* -MILKIFIER! guaranteed" with the DE- and MILKIFIER! appearing shifted onto two separate text lines. she assumes some manner of old timey logo must've been between the words. the machine doesn't inspire confidence, but it appears to have electricity powering it, and she's desperate to get milked, so she slips them on and flips the switch. the machine rapidly powering on makes it shudder a bit, the dust falling away to reveal the sign actually said "Professor Lactatia's DE-LUXE EN-MILKIFIER! guaranteed to triple your tanks!" as the cups stretch to stay around her breasts, as they suddenly and rapidly begin to balloon in size to more than 4 times what they were, milk spewing forth into the hoses and collection tank, the cow girl bemoaning (or again be-moo-ning if you will) how this is the opposite of what she wanted, yet can't deny she likes how it feels.

Axel Lamperouge

If you don't mind a sequel idea to a previous pitch. While working on the spell to reverse Penny's fertility goddess state Mrs. B interrupts her daughter, getting hit with an even more powerful spell. Mrs. B's boobs grow so large they replace the earth with people now living on her twin mounds and worshipping their milf fertility goddess

Curiousonlooker

(I think the idea I had got disappeared, so I'll rewrite it) The Harlot Knight's adventures continue, but there has been a curious new development; between all the traveling, daring athletes and acrobatics, fighting, intense fucking, and Drainings of milk to sell for room and board, Sofia is growing bustier, lustier, milkier, and perhaps even curvier (if you wanna include some booty/hips/thighs into the mix). Others would be dismayed if not crippled by this, but this is the nymphomaniac Harlot Knight; as her hyper productive and often leaking breasts swell further before her and down past her now perpetually sopping pussy towards her knees, when not stuffed haphazhardly into her far too small armour, her might and power rises to match it, allowing her to fight and move just as easily as before. What's more, all the movement and stimulation, not to mention all the attention her ever more luird form garners her makes her all the more lustful, and this lust, along with the lengths she goes to satiate it, creates a cycle of depravity that often leaves her feeling larger and heavier with each passing day, and she couldn't be happier. This is a new Sofia; a bigger, sluttier, stronger Sofia, and the evils of the world better be ready for her.

FurryBound

My OCs Scarlett & Rosemary essentially being bound and gagged by their own breasts— Scarlett caught between Rosemary’s massive mounds (and since they’re in a cramped space, Rosemary is effectively pinned to the wall by her own breasts), meanwhile Scarlett’s own bust has grown big enough to press against/stuff both their mouths!

Stevie J

It would be nice to see Penny's mom

D-Man

Sorry, I should probably know this, but Milky Way Spacers? What does that mean?

UDDERScomix

It's $3 tier that you are a member of. Basically, if you can see my full color comics, then you can submit. :D

UDDERScomix

It's like they are in a reverse Tardis! Not only is more cramped on the inside, it makes them grow!

UDDERScomix

This is fantastic! Love all the thought you put into this! Amanda will be pleased!

UDDERScomix

There would be not "Flat Earther" here! Great idea!

UDDERScomix

What I love is that I too had to press "Show More" to read the DE-LUXE EN-MILKIFIER" I think that the bimbo hucow version of Mrs. Boobalickski would be great for this!

UDDERScomix

WOW! This hits a lot of sexy buttons! Penny in a sexy space suit AND breast expansion! Nice! Talk about the GOOD kind of a Chest Burster!

UDDERScomix

Veronica is gonna end up getting her own comic series at this point! Great idea!

UDDERScomix

I love that too! Whenever I hear a recipe that requires milk, I'm like, "But you know what would make that even better?" ; )

UDDERScomix

I've been to Niagara! And seen the movie Niagara. So this would make for the perfect trifecta! Great idea! Also, Trifecta would make a great name for a three breasted character! XD

UDDERScomix

The best part is she is clearly drunk, strawberry champagne daiquiri in one hand! Too bad the simple syrup had more than sugar in it! XD Great idea!

UDDERScomix

Ishtar's Tits! Heifelia going super bosom! Medowlyn brace yourself! Great idea!

UDDERScomix

Very interesting idea! I do have an idea for what Mrs. Sweet Buxom is like, so if this wins, it would make for a VERY interesting introduction!

UDDERScomix

It's a race against the clock! Great idea!

UDDERScomix

This fits in really well! I can already see the cover of the half open Mammoire on the floor!

BodyMageBill

Hehe let me know if you ever need a world-building guy 😁

JayAury

An adventuress discovers a mystical amulet! But donning it turns her into a hugely busty, mooing holstaur.

Connie Edogawa

and I think the bimbo hucow Mrs. B would be great for sweeping off her feet and taking as my wife. ......I mean what? who said that? >.>

connmer

Penny places a bet with Ess to do a 30-day “No Milking” challenge. Massive expansion ensues as the pressure builds, but Penny won’t give up.

D-Man

Oooohhhhh... Guess I've been a member so long I forgot.😁😁

David Rudisill

Mrs. Boobalickski is at the Tiddy Dippers when her tiddies suddenly grow so large, they destroy that little bitty building. [The Tiddy Dippers owner built that thing to code, and if you believe that, I've got a bridge at Garcon Point near my hometown to sell you.] Of course, the toppings get smeared all over Mrs. B's honkers, so now it's FREE TIDDY LICKINGS DAY!

UDDERScomix

You can hear the sound of guys and gals from all over Heiferchester running to get some free samples! XD

UDDERScomix

HAHA! Nice! One tiny tap and SPLOOOOOOSH!

David Rudisill

I'm also curious to see how Penny's mom got it going on as well.

David Rudisill

Worst traffic jam in the history of the town! Really, everybody wants some. https://www.youtube.com/watch?v=4EI8JN-fSLo&list=RD4EI8JN-fSLo&start_radio=1 [Van Halen, "Everybody Wants Some"] The song is a total banger by itself, but when it was used in the burger claymation sequence in "Better Off Dead," I LMAO'ed so hard! The cherry on top?! The restaurant boss Rocko who unceremoniously fires John Cusack and interrupts the Van Halen sequence is played by Chuck Mitchell, who played the owner of the TIT-ular night club in "Porky's" and in the sequel "Porky's Revenge."

Mr. Semaj

I'd love to see Penny's mom ❤️

Chumlee99

personally at the moment, the vision I'm seeing is Penny's Mom could go in either one of 2 directions. Direction 1 is she's more like an Aunt Sharon type but like one of those BBW MILF wine moms who can still get all the guys and gals who's always got the perfect hair and teeth and clothes and all that (And obsessed with being the biggest bust around) or Direction 2 is she's like the perfect cartoon 1950s housewife who even now still has a libido to outmatch any of them, but she's a lady and still somewhat in the closet about how naughty she really is and yet she's also in denial that her sweet tooth has caused her figure to explode in size and she produces gallons upon gallons of milk she uses for her own cooking but never tells anyone what her secret ingredient is.
