Nicky's breasts are rising above the walls of the bathroom stalls even as they knock them down. She is standing at their top, thrusting furiously, her enlarged ass aloft and basketball-sized nuts swinging behind her. A geyser of cum is jetting from the front of her cleavage, steadily flooding the room. The bottom panel is a close-up of her face, drooling and eyes rolling back as neon hearts gush from her irises. The word MORE echoes more and more boldly across the page as she gasps and moans.

part 11 ✨
#breastexpansion #dick #cum #nicky #sbtart

Nicky props herself up atop her massive boobs, raising her hips high. The words cum, grow, more, more, MORE repeat about her. Her clothes are beginning to shred. In the bottom panel, she thrusts forward with force, reeling her head back as the word MORE repeats feverishly in the background. Her irises are a vibrant pink and leave a trail of hearts.

Her massive dick emerges from a wall of cleavage, breaking down the door of the bathroom stall. A firehose of cum splashes against the sinks and mirrors on the far wall as the sides of the stall give way to breast pressure, white splashing everywhere.

parts 9-10!

the same girl is blushing and flustered, her now massive chest and backside fully escaping her uniform.

"Ggh- AH"
"Did you JUST make another wish?"
"I w... I wished that I w-wasn't as big as I was..."
"Wow, you are just wildly bad at syntax."

a server with an exagerrated hourglass figure, boobs and ass practically spilling out of her waitress outfit, is kneeling before a milkshake spilled on the tile floor. she has a grumpy pout as she ineffectually adjusts the strap digging into her huge tits

"What exactly did you wish for again?"
"I wished... that I would get big tips from all the tables I wait on..."
"And how many tables have you successfully waddled your ridiculous body to?"
"HEY, I made it to one!"

nophica ffxiv is readying a cast titled Overabundance. she's leaned forward showing off her deific cleavage, holding her scythe, flower petals blowing around her

no one interrupted the cast bar, so everyone got hit with the Overabundant debuff, slowing them and dropping their defense as their fat tits rip their armor. except the Lalafell, that bust slider is purely decorative. i'm also going to say fun words like miqote miqo'te viera au'ra breast expansion boobs ahegao, for the search function.

a blonde cheerleader and a nerdy redhead with glasses are exploring a haunted house. the redhead is holding a flashlight and looking back at her companion. the blonde has a hand on her friend's shoulder, and her figure appears to be filling out into an exaggerated hourglass as her shirt and skirt shrink. her gaze is flustered and vacant and her eyes are glowing a supernatural blue.

same as the first image, but a mischievous ghost is visible passing through the cheerleader and poking playfully at her ballooning boob.

the cheerleader's curves are even more exaggerated.

the cheerleader's curves are starting to occlude her as her tits grow past the nerd's shoulder. the redhead looks down nervously as her own chest seems to be getting larger.

"Pray tell, our dear stalwart WARRIOR OF LIGHT. Might you know of any strong -emotional urges- that could be affecting the dynamis on this little excursion?"

her ballooning boobs are lying on the ground in front of her, spraying milk pooling around them. her composure is broken. "A-ah, please, I'm gonna- I'm gonna- f-FROTH AND FOAM"

nicky is in the bathroom stall grasping at her massive boobs, her torso and giant dick sandwiched between them. she has painted the front of the stall white with jizz. the narration reads, "As surely as she filled her space, the week-ending release emptied her mind. Her panic from just moments ago was replaced with one word, echoing with feverish certainty." in the second panel her expression is zoomed and feverish, as the word MORE occludes her.

nicky feverishly wraps around her dripping, tree-like erection. hearts are emitting from her irises as if pure horny was replacing reason. she is struggling to stroke the appendage due to its size. the narration reads, "She couldn't imagine why she would deny herself that feeling, that state, for an entire week. For a day, for a moment. Why would she ever want to not feel this way? To stop GROWING, and FEELING GOOD"

She has planted her feet against the wall behind her as her breasts fill the entire confined of the stall, her veiny dick stuffed between them. her attempts to grap it at all seem futile as it rises above the stall's door. the narration simply reads, "And GROWING, And FEELING GOOD, and GROWING, and CUMMING, CUMMING, GROWING," swiftly devolving into the words CUMMING and GROWING littered with hearts.

a blue-haired girl is obscured by a pile of her own boobs, belly, ass, and thighs, each dwarfing her original mass. she seems to be lost in pleasure while repeatedly clicking a button in one hand

a flashback to the same blue haired woman with very modest curves immediately before the procedure. she's furrowing her brow indignantly at a huge white bikini she's holding. "What do you mean put this on? Is this a joke?! You're just supposed to give me a couple cup sizes!" "Well you see ma'am, for liability reasons the procedure is self-regulated..." "What's that supposed to mean?! I'm not some sort of tit-crazed bimbo!" "...Of course ma'am."

Yeah yeah, everyone's a bastion of self-control until they're holding the plump button

Lily is sweating nervously in a crowd of people, hunched over in a futile effort to hide her growing boobs behind her puffy jacket. she's clutching her white button-up shirt above and below her cleavage with either hand, seemingly having given up on getting the buttons to meet at the bustline's equator. she's imagining a tube of pillsbury biscuits bursting open in a thought bubble.

Lily is fine and everything is under control 👍✨ (for @wolfafterhours.bsky.social)

cute doggirl vtuber mocha is lifting her desk as her boobs grow underneath it. her gaming chair is shattered and the seat is clinging to one cheek by its armrests. she's holding her mouse aloft, her breasts are spraying milk against the wall, and several rectangular "size up" point redeems are scattered on the floor. Tomi the bull is in a cutaway panel, wiggling his raised hands from behind two beachball boobs. the dialogue reads, sfx: CRACK CRASH "Uh, what was that?" "Nothing. Don't worry about it." "Mocha. Did you check you chair's weight limit for your new model like we talked about?" "It's fine. Nothing happened. Tomiii, can you send me to the brb screen? I can't see my keyboard..." "Yeah about that"

first panel, tomi is lookin like a gremlin saying "yeah chat, just wait. her new model's got them bean bag chair tiddies". mocha holds a hand up to he face smugly, responding with "what, that small?" second panel, text reads "one hubris later". "size up +" redeems costing 1,250 points fill the air around mocha. her shirt is hanging on by threads with beach ball sized leaking titties barely contained in it. she's wailing to the heavens, blushing and sweating nervously, "chuh... chaAat. i was kiddiiiing". her butt is visibly constrained by the armrests of her chair.

Tomi the tomboy model bull is reduced to about 4 heads tall. Sleeves are too long for arms, thighs are breaching stockings. Boobs are spilling out from under his white t-shirt. In another panel, Mocha's hand is rapidly mashing a button labelled "shortstack togglizer". He insists, "Okay, shortstack toggle definitely works! You can uh, give me back the button now." "Mmm, no I think I like this clicker."

"Eep", he says as he becomes even shorter somehow. He is mostly curves. You can see some nipple peeking past a clearly visible cowprint bikini modesty top. Mocha is grinning in a cutaway panel, holding the remote. "Say 5 foot 6 is tall"

yomi the blueberry-esque glad scientist tiefling vtuber is becoming more of a pear. she's holding a steaming, sparkling flask that is clearly peach-flavored, compounding the complexity of the fruit metaphors. her thigh-high stockings are holding on for their life, mourning the loss of their skirt friend. she looks downward at the potion's effects. "Potion for improving gamer chair comfort during long streams has yielded... unexpected results. Formula could definitely have marketing applications..." She grins. "This requires further testing~" A narration box is in the corner. "Alas, she was unable to bypass the padlocks on the agency water coolers."
