With Julie knocked out, Sophie, still clad in her bra and panties, helped herself to the flatscreeen TV and sweets in her friend's house. She waited until darkness fell. Then, while viewing a interesting movie on demand -- what was it, Invasion of the Fatty Eaters or something...? -- she glanced at the readout on the cable box. "Oh!" she exclaimed, dropping a bag of Mallomars. "I better go up there before she breaks the bed." Uncrossing her fat legs, she bolted up and hurried her jiggling body upstairs.
Sophie's thudding footsteps grew quiet as she approached Julie's bedroom. Standing on tiptoe, she crept through the door and peeked inside. Upon seeing her handiwork tied to the bed, Sophie covered her mouth to stifle a gasp.
Julie lay sprawled on top of it, her arms carelessly flopped out beside her head, and all corners of her body fattening like a blimp in all directions. Julie's panties, unable to cope with her expanding ass, had rolled down to her thighs, pulling into a tighter and tighter band as her fat insisted on growing. The rolls on Julie's distended belly now looked like a pair of lips, quivering their sides together with each strenuous breath. As Sophie drew nearer, she could glimpse past Julie's prodigious belly to her tits, which had also grown scarily huge. Somehow, the calorie drink fattened them from a size C into enormous mounds, barely held in check by her straining top.
* C-C-CRRREAK.... *
"Uh oh." murmured Sophie. Maybe she should have come back sooner?
The ropes tying down Julie's arms and legs had begun to wince loudly. The biggest crackling was coming mostly from the bedposts, which looked like they were buckling inward.
Sophie had never felt a urge like this before. Licking her lips, she stared at the dark outline of Julie's nipple poking through the fabric. She reached a cautious hand over to Julie's slumped-over breast, fondling the flattened nub with her finger. Julie responded sleepily, moaning as her fat body writhed from her fingers down to her toes.
"Better do something quick...." Sophie responded. "I think these ropes are gonna blow." The knots continued to twist slowly against Julie's blubber, digging deeper as her weight continued its climb. Julie wiggled her fat toes, unaware. She smacked her icing-smeared lips pleasurably and shifted around in her sleep, causing the ropes to creak even louder.
Quickly, Sophie bent over and dug out a knife from under the corner of the mattress. She plucked at the ropes connected to Julie's ankles and wrists, causing them to fall back with a crash. Gingerly, she then snipped away the remainder of her friend's clothes. "Mmm, Julie, you're looking so yummy." sighed Sophie. She laid her hand on Julie's dense belly and felt it vibrate.
Sophie's mouth watered; she couldn't wait any longer. Huddled at the end of the bed, she took Julie's ankle and put her lips around her toes, feeling them wriggle. Suddenly, she felt the pillowy sides of her friend's foot sliding into her mouth. This was followed by Julie's heel, which fit effortlessly in Sophie's mouth, then the ankle, and before long, Sophie felt her mouth stretching to accommodate her calf. The sensation of Sophie's warm tongue caused Julie to burp, and she teasingly slid the other foot forward. Sophie pounced, sloppily stuffing Julie's toes into her already-crammed mouth. The porcine skin of Julie's ass and thighs offered no resistance and Sophie effortlessly devoured them, her lips sliding over each roll of fat like a speed bump.
