Part Four

By the time Casey’s experimental hormone pills started to kick in, Tina had grown all the way to an R–cup. She spent her weeks focussed on classes but came over to their apartment every weekend. It was lucky for all three of them that Casey’s photo sets and videos were selling so well, because they spent a small fortune keeping the greedy blonde fed.

“Hey Tina, is that a new blouse?” Casey watched Tina cross the living room to the couch where she sat editing photos on her laptop.

“Yeah, do you like it?”

It was a simple button up shirt in pale blue that complemented Tina’s eyes. Casey wondered where the blonde had even found the garment; it managed to cover her watermelon boobs only snugly, while the short sleeves weren’t too big for her thin arms.

“I do, it’s super cute.”

“I had to get new jeans too…” Tina turned to show Casey her bottoms, which clung to a set of ass cheeks like two volleyball halves.

’I guess it was inevitable that a few pounds would make their way down there…’ Casey would have to expand her list of potential cosplays to include characters with a little more curves than just tits.

“Those are nice too.” She said brightly.

“It seems like I’m outgrowing my clothes every few weeks. It’s a good thing our photos are selling so well.”

“Believe me babe, your photos do even better the bigger you get.”

Casey hopped up from the couch and put her hands on Tina’s soft waist.

“That Chifusa set already has more sales than our Witcher photos. We’re moving into a more specific niche, but that just means people will pay even more to see these babies get bigger and bigger.” Casey pressed Tina’s breasts together, making the buttons down the front of her top strain, fabric puckering and soft thread creaking.

Tina leaned in to kiss Casey, grabbing the Latina’s above–average chest in her own hands. Then she pulled back with a surprised expression.

“Are you getting bigger too?”

Casey grinned broadly. “I wondered if you’d notice. It’s just one cup size, but yeah…” Casey found Tina’s nipples through her shirt and industrial–strength bra. “I couldn’t let you have all the fun.”

Weeks became months as the semester rolled on. Casey had to upgrade all her bras and tops before fall break, and then again after the holidays. She made it a point not to make or order costumes too far in advance, just in case either of the two women outgrew them before the shoots.

Casey stood in the small studio space checking herself in the mirror. She brushed her fingers through the long blonde wig and straightened the set of horns curving out from the headband the wig covered. She wore a lace headdress with a dark blue and white maid’s outfit. Tina emerged from the bathroom in a short black wig with purple tips. Her outfit was an ‘office lady’ skirt and jacket, with a white shirt under a blue–grey sweater.

“This –uh– this blazer won’t close, Case…”

“Sure it will, come here.”

Casey tugged the jacket around Tina’s narrow waist and closed one of the three buttons. Tina’s enormous breasts stretched the sweater tight and pushed the sides of the jacket open around their girth. Tina appraised herself in the mirror.

“I look ridiculous!”

“Trust me babe, it’s perfect.” Casey pulled her phone out of a pocket in her wide skirt and pulled up an image. “See?”

Tina looked at the fan art of Elma from Miss Kobayashi’s Dragon Maid, then looked at her reflection again.

“Oh, wait!” Casey exclaimed, crossing to the props table. She grabbed a pair of wire frame non–prescription glasses and returned to Tina. “Here you go. Now it’s perfect.”

“I’m –uh– a little bigger than she is.” Tina put a hand on the underside of each sweater clad breast, straining to lift a set of tits the size of small exercise balls.

“Yeah you are.” Casey said suggestively, putting her hands over Tina’s and helping the blonde lift her overgrown breasts. Tina let out an aroused whimper and her face flushed pink.

“Oh that’s great! Let’s do the first pose…”

The two women stood face to face glaring at each other. They stood back to back grinning smugly at the camera. They didn’t do any full ‘shipping’ poses like some of their previous shoots, but they did stand close enough together to show Casey’s H–cups pressed against Tina’s T’s.

“Okay, I want to do one quick costume change, and then a set with just you, okay?”

Tina stood at the nearby table, resting her chest on the surface. “Okay…”

Casey stepped up to Tina and lightly massaged her massive breasts as they rested on the table.

“Just a little longer, okay? Then we can eat! We gotta keep the photo sales coming in so we can keep these babies well–fed, right?”

Casey’s own stomach grumbled hungrily.

“And mine too for that matter…”

Tina reached over to fondle one of Casey’s breasts through her maid outfit, and the girl cosplaying Tohru leaned in to explore Elma’s mouth with her tongue.

Tina’s second outfit turned out to be blue sweatpants and a white shirt that said “EAT” in light blue outlined letters. Casey helped Tina out of her office lady clothes and into the sweats, which hugged the blonde’s slightly wider hips and more than bubble butt perfectly. The shirt proved to be a problem. Tina popped her head through the collar easily, but when she tried to pull it down, it got stuck just above the apex of her vast bosom.

“I don’t think this is gonna fit, Casey…”

“Sure it will, let me help you.”

With four hands, the two women were able to inch the white tee over Tina’s massive chest, being careful not to rip it. Under her bust it just barely reached her torso again, leaving her entire midriff exposed.

“This thing is seriously crushing me.” Tina protested.

“Trust me babe, it’s perfect. Your fans are gonna eat it up. Actually, that gives me an idea!”

Tina waited with annoyance while Casey ran to the kitchen, returning with a brown paper bag.

“Here, hold this in one arm.”

Tina looked in the bag and saw it was full of donuts.

“Casey, what—“

“Hold this in your arm, then eat the donuts while I take the pictures.”

“Won’t that be kinda weird?”

“Just trust me.”

Casey took a few hundred photos while Tina ate, then a dozen or so more without the donuts. By the time they were done and Tina was able to change back into her own clothes, the blonde was almost too exhausted to eat their actual lunch. Almost.

Tina came over on December 23rd so the trio could celebrate the holidays before going home to see their respective families. When Joseph opened the door for her, she was weighed down with two overstuffed grocery bags (and a good fifty pounds of tit flesh).

“What’s all this?” Joseph asked.

“Well, –hrng– you two buy so much food for me, –haa– I figured I’d contribute my fair share for once.”

Tina bent slightly forward, nearly toppling to the floor from the weight of her massive chest; she swung the grocery bags up to drop on the kitchen table with a thud.

“You don’t have to do that, babe.” Casey said, wandering out from the office area.

“Meh, it’s the holidays.” Tina fished a hand into one bag and pulled out a quart carton. “I hope you like egg nog…”

“Oh Dios mío, I’ve been craving dairy like you wouldn’t believe since I started taking these pills.”

Casey flounced over to snatch the carton from Tina’s hand, volleyball size breasts bouncing in her tight ‘ugly sweater.’ She unscrewed the top and lifted it to her lips.

“Don’t drink from the carton, mija…” Joseph protested.

Casey ignored him, throat pulsing as she chugged the thick, sweet liquid. She drained a third of the carton before coming up for air.

“Aahhhh that’s the stuff! What else did you bring? Our DoorDash won’t be here for another half hour.”

“Oh, just some cookies…” Tina said coyly, grabbing the bottom edges of the plastic bag. A small mountain of Oreos, Chips Ahoy, and Keebler Fudge Stripes spilled onto the table.

“There’s also four more things of eggnog in this one.” She tapped the second bag proudly.

“You did good, babe.” Casey stepped up to Tina from the side — there was too much tit between them to reach her directly — and planted a wet, eggnog flavored kiss on the shorter girl’s lips.

The trio watched the latest cheesy Netflix Christmas rom–com and the two young women snacked. Joseph produced a bottle of white rum and the eggnog became an adult beverage. By the time the proper food arrived — so much Chinese food the poor delivery boy could barely carry it all — they were all well–buzzed and the girls were comfortably full. That of course didn’t stop them from going to town on potstickers, spring rolls, and an endless parade of sugary golden lumps of fried chicken.

When the movie ended and Joseph was queuing up the next one, the girls undid the buttons on their pants, letting their stuffed tummies stretch out so they could keep eating. Halfway through the second movie, Casey shook the few remaining drops of the last carton of eggnog onto her tongue. Tina sat in the middle of the couch, so the couple leaned on each side of her when the food was gone. Casey and Tina both rested hands on their stuffed bellies, warm to the touch and rumbling with the effort of digestion.

Some time during the third act of the second movie, Tina glanced down at Casey’s oversized — though still much smaller than her own — chest and noticed dark patches spreading across the front of her green and blue striped sweater.

“Uh, Case…”

“Hmm?”

“I think you got something on you.”

“Huh?”

Tina pointed at the Latina’s chest, and Casey craned her neck to check herself.

“What the hell?”

“What’s the matter, mija?” Joseph asked.

“I… I think I’m leaking!”

“What?” Tina blurted. “Like… leaking milk?”

“Yeah!” Casey hurriedly pulled the sweater off her head, revealing a pair of breasts swollen to nearly basketball size. The flesh was spilling over the edges of her bra cups and surface of her skin was shiny and taut. Blue veins laced across the swollen orbs, and white liquid dripped from the soaked bra.

“Are you –um– pregnant?” Tina asked.

“No! I had a scare a few months ago, but I switch to a new birth control just before…” Her eyes widened in realization. “It must be the pills!”

“Your… your boob pills?”

“Don’t call them that, but yeah! Help me get this off…” Casey leaned forward so Tina could unhook her bra.

With the release of her overtaxed bra, Casey’s breasts dropped down just slightly on her torso. They were fat and full, much more firm than usual. Joseph stood and was hovering near the two women, wishing there was something he could do. Tina slid up to the edge of the couch and stared at Casey’s exposed nipples. They were dark brown, darker than normal, and her areola were puffed up. As the blonde watched, a drop of milk crept out of the thumb size nub, dripping into Casey’s lap.

“Yeah… you’re definitely lactating.”

“Dios mío…”

“Can… can I…”

Casey nodded with a wince. “I didn’t notice it before now, but they’re actually super tight. I think I need to get this milk out of me.”

Tina knelt on the floor and rested her massive breasts in Casey’s lap. She took one of Casey’s light brown boobs in both hands and touched her tongue to the erect nipple.

“Haaa!”

“Sorry!”

“No it’s okay, they’re just really sensitive. Keep going…”

Tina pressed her open mouth to the surface of Casey’s areola, closed her lips around the engorged nipple and gave a tentative suckle. She was rewarded with a thick stream of warm, sweet milk. Casey let out a sound that was half moan, half sigh.

When Casey’s eyes opened again she looked up to see Joseph watching them. She glanced down at her unoccupied breast meaningfully. Joseph shook his head.

“You know I’m sensitive to dairy…” he muttered.

Casey sighed and ran her fingers through Tina’s blonde hair. The outrageously busty girl was gulping greedily now, but Casey pushed her away and guided her to the other breast.

“I guess it’s all for you, mija… I hope you’re still hungry.”

Tina licked milk from her lips and leaned in eagerly to drink from Casey’s other breast. The Latina beckoned her boyfriend to join her so they could make out. Joseph worked one arm under Tina’s breasts to reach his girlfriend’s damp sex. As his fingers worked their magic, Casey could feel Tina’s still–packed tummy pressing against her legs as it filled up tighter and fuller with milk from her own body. When she came, her unoccupied breast released milk in a spray that soaked Tina’s sweater as well.

Casey wondered how much bigger the blonde would get from her ‘nutrients.’
