Mary, arms full of bags of food, waddled into her house. A deep hunger to stuff herself silly was starting to become very powerful. Jess was laying on the couch, hands holding a her own large belly. She had developed further albeit slowly without the nourishment of food. Jess's flattened piglike ears perked up and she snorted.
"Bout time!" Jess squealed and with some difficulty, unused to her new weight pulled herself up off the couch and and speed surprising both of them lunged at a bag and ripped it open, spilling it contents all over the floor. Crackers, candies, and other goodies scattered everywhere. Jess, overcome by her own hunger dove for the nearest food stuff. A box of donuts. A greedy hand grabbed the nearest one and shoved it into her mouth.
Mary giggled, then snorted, her nose had grown larger and her nostrils were flared. "Save some for me!" She reached down and took a box of donuts for herself and flopped onto the couch, she took a couple and devoured them in just a couple of bites. "Oh my god! These taste sooo good." Two more went in, slacking her hunger just a bit. Enough to where she didn't feel the need to gorge as fast as possible.
The same couldn't be said of Jess. She'd been too long without food. She was eating as fast as she could and also changing just as fast. The food was fattening her up. It looked like she had been hooked up to a hose and was filling up like a balloon. Her blouse and pants started to strain against her massively rotund frame. She didn't care, she was stuffing donuts down her throat. It felt so good. It filled her hunger, the emptiness was being replaced by the feeling of pleasurable fullness.
"Jess!" Mary oinked. "Slow done, girl!" She reached down and put a three fingered hoofed-hand on her friend. Jess looked up from the donut box. Crumbs fell from her mouth. A mouth that had elongated into a small snout. The large nostrils of a pig sniffed the air. Jess grinned and burped. She was coming along nicely. Large and fat. Her limbs were shorter, but she still retained enough of her human self to be able to stand and move.
"Oh!" Jess snorted. "That was amazing." Jess pulled herself up off the floor and sat next to Mary. Her clothes still contained her frame, though her blouse was straining on the buttons. "I love this. Being a pig, being fat. God, such fun!" Mary grinned and fed her friend a donut from her box. Jess couldn't refuse.
"You're not done yet." Mary grinned, running a hand over her friends fat belly. She felt new breasts forming under Jess's original ones. Another donut and another were fed into her friend. "Let's get that shirt off." Mary said as the last donut was eagerly accepted by Jess. Each morsel adding fat to Jess's frame. Thread and fabric strained and started to break and rip. Mary caressed Jess's belly and ran a hoofed-hand over her mounded breasts, Jess moaned. A gallon of milk was opened and Mary began to pour it straight into Jess's mouth.
A loud pop and a button went flying. More milk and Jess swelled enough to break the reach of the blouse open. Her flesh flooded out constrained no more. Six breasts, each pair smaller than the one above greeted the two. Jess snorted, guzzling milk, some splashing around her and onto her ample pig frame. The gallon was gone and Jess was huge. She snorted in pleasure and contentment. Mary licked some of the milk off her friend and opened a package of cookies, munching on them herself this time.
The two pig girls let the food settle, their hunger, for now, slaked.
