When they first head that every calorie they ate would go straight to their asses, they either scoffed or cheered. Surely not every single calorie would go right to one place and even if it did, who would complain about a little more junk in the trunk?
That was before they found out how many calories were in a single large milkshake.
Pleasure clouded over Ruby's eyes. The sweetness on her tongue was overwhelming and there was nothing she could do but chug and chug and chug. Each loud swallow seemed to ripple through her body, making her tits jiggle and her belly slosh, until it reached her lower half. Her thick thighs and wide hips and plump ass didn't just wobble, they shook, each swallow forcing them to move and to plump up even bigger. Melted ice cream ran down her chin and dripped onto her tits as she pulled the glass away. She hadn't been breathing as she drank and so now she gasped for air. Her heart thundered in her chest. Her tongue darted out to clean up the dribbles on her chin only for her to bite her lip as she examined herself. A chubby hand reached out, fingers splayed, and sank into the softness of her thigh. A moan burst from her, taking even her by surprise, trying to suppress it a moment too late by biting her lip. She was so fucking big...
The now empty glass joined three others beside her bed and Ruby cringed at what she had done. Sheepishly, she turned towards you. "I know... I know I shouldn't have... But, fuck, I'm so big now! I'm fucking gigantic! I'm taking up half the fucking couch and my ass is lifting me way up in the air! I should have stopped after the first one. I shouldn't have had any more. I was so upset when my ass started ballooning; I was sure I wouldn't dare have another one. Then it started to feel good. Fuck, babe, it feels so sooooo fucking good. I've never been this sensitive before and I finally have an ass! I have an ass bigger than anyone who ever made me feel self-conscious about my body! Bigger than all of them combined! Plus my hips and these thick, plush thighs..."
Ruby gave them a wobble and bit her lip again, this time ready for the intense sensations that jolted her body. Her cheeks flushed with arousal as her gaze returned to you, breathing heavy and ragged. "You could have said 'No,' you know. I would have stopped—might have stopped—but you kept getting me milkshake after milkshake. Even when I ripped clean out of my jeans, you kept them coming. You know what that tells me?" Flexing her thighs and shaking her knees made her colossal thighs ripple against each other. Arousal struck her, but she never looked away from you. "That tells me you wanted this, too. You want to see how big I can get. You want what I want. So let's do it, baby. Go get me another one, I—" Ruby's stomach gurgled. Her hands flew to it just in time to let out a large belch. As it faded, she let out a giggle, rubbing her tummy. "I've got plenty of room for more~"
