Twins Weight Gain

Round Two

Jade and Jason were once again sat at their kitchen table with Ryan between them. In front of them was dozens of shakes, Ryan wouldn't say of what. Jason's stomach still ached from earlier and Jade was looking a little green as she glanced over the shakes. Jason was beginning to wonder how far this was really going to go.

When he woke up from his nap he expected his stomach to have mostly deflated and for his abs to be somewhat visible but they weren't. His lean figure was already average again after the first round. Jade had also noticed some immediate changes after she woke up. She was always a little pudgy but she had worked hard to lose fifteen pounds in a healthy way over the last year. Now, she felt like she had already pilled them all back on. Which wasn't possible surely. But her whole figure was definitely softer.

"You guys had one of these already at breakfast, it's a weight gain shake that farmers use for livestock."

Both the twins turned to him with their eyebrows raised and Ryan instantly rushed to defend himself, "It's the quickest way to gain weight and it also means the quicker way to find a winner to this challenge. Agreed?"

Both twins nodded their heads.

"You both have roughly two gallons of that shake in front of you. I don't expect you both to finish it though because I'm giving twenty minutes to drink as much as you can. Winner is whoever drank the most, spills will affect that though. You guys ready to chug?"

Jade and Jason nodded their head and ready told them to go. Jason was quick to chug his drink while Jade took sips. It seemed to be working well for Jason at first but he was quickly starting to struggle as he got about a third of the way through his first gallon. 

He felt like the liquid was just resting on all the food he ate earlier and he was quickly full. He panted more and more, only able to take short swigs from the gallon before he had to rest. Across the table Jade was moving at a far more consistent pace and at the halfway mark she was nearly finished her first gallon.

Ryan shifted uncomfortably in his own seat as his dick got hard, watching the more dramatic effects this had on the twins bodies. By the time the twenty minutes was up, Jade was the clear winner. She had first her whole first gallon and made a decent chunk in the second one. Jason had just about finished his first.

Jade's shirt had fully ridden up this time, looking more like a crop top than a t-shirt. Her stomach was extremely distended on her smaller frame and rock hard. The shake was dripping down her chin and Ryan swore it looked like she was already forming a double chin. On the far side of the table, Jason's shirt had also started to rise up this time, making it look like he had a beer belly.

Ryan scooted his chair over to Jade and gently rubbed her belly, "looks like the score is even at the end of the first day."

Jade's eyes were half closed and she just offered a weak smile in return. Ryan leaned forward, "What would you like your prize to be?"

Jade thought for a moment at how nice the rubbing on her stomach was but then she caught a glimpse of her brother looking completely defeated across the table and had an idea.

"I want Jason to drink the rest."

Both Jason and Ryan shot up and stared at her in disbelief. Jade had decided that it wasn't who gained the most weight but whoever dropped out first lost. Her brother looked like he was ready to throw up, maybe this would push him to quit before they did any serious damage to their figures.

"Me?" He asked and she just nodded.

"I'm going to go to sleep and hope this gut goes down, and you can drink the rest." She smiled cheekily as she slowly rose to her feet and left the room, but not without winking at Ryan who by then had worked out what Jade was trying to do.

Ryan sighed and pushed Jade's over half full bottle down to Ryan alongside his basically full one. He then grabbed a funnel and tube from a bag he had brought with him and kept in the kitchen.

"Open wide," Ryan said as he pushed one end of the tube into Jason's mouth. Jason wanted to protest, now realizing what his sister was doing but he was tired. Plus, he grew warm at the idea of Ryan stuffing him.

Jason closed his eyes for the next thirty minutes as he drank the gallon and a half extra of the weight gain shake. His stomach was crying in pain but he just kept swallowing and swallowing, trying to think of where he was going to take Ryan out but also at how he could get back at his sister for this.

Jason could feel the cool kitchen air on his stomach but he tried to ignore the sensation the best he could. Ryan on the other hand was drooling as he watched Jason's body expand and change with the effects on the shake. Like Jade, Jason's top was practically cropped as he forced down the last few drops of the shake.

Ryan however also noticed his body already seemed softer all over. Jason's thighs were nearly touching in the chair already, not to mention it looked like his once firm pecs were beginning to soften under the t-shirt. And it was undeniable that he had a slight double chin where he once had a sharp and chiseled jawline.

Ryan took out the tube and if Jason noticed the changes, he didn't say. Instead he just waddled out of the room and upstairs without even saying goodnight to Ryan.

Ryan had held a tiny detail from the twins however, that the shake wouldn't going through them like ordinary food, rather get absorbed with the rest of their fat as they slept. But, they would realize that soon enough once they woke up...
