"Of course!" Vanille shouted, and tried against the laws of physics to drag Fang along at her running pace. Realizing that wasn't oging to work, Vanille skipped ahead anyway out of enthusiasm. Fang raised an eyebrow with a small smile when she saw Vanille's already short skirt flapping against her new, rather flabby rear end.

Vanille was out of breath and a little sweaty from the 15 seconds of jogging, and leaned against one of the attraction's gates, panting, as she waited for Fang to truck her gargantuan rear end over to the ride. Vanille's spirits dampened briefly. "I love your new diet, Fang, but we'll never fit in the same boat!" Fang brought a finger to her lip. "Damn, you've got a point...wait a second, take a look at that!" Fang's eyes lit up as a boat floated placidly over to the landing the girls were waiting on. It had the typical rowboat-shaped design with a large heart design making up the back, only the heart seemed to be painted to look like it was made of chocolate, and the boat looked like it could have fit the thin versions of Fang and Vanille five times over. Still, on the side it had a very bold, very clear message: "NO MORE THAN TWO TO A BOAT; STRICT WEIGHT LIMIT ENFORCED!"

The girls boarded, and found that their overweight selves barely took up half the bench. Fang smiled. "I feel so thin!" scooting up and down the bench a little for emphasis. Vanille hopped slightly from where she was sitting to bring her butt down next to Fang's as close as possible, to the point where their love handles were rubbing. When Vanille landed next to Fang the boat rocked rather severely for a moment. Fang grinned. "Watch yourself, don't forget your little tackles are starting to count as heavy ordinance!" She slid a hand over Vanille's chunky thigh and gave it a squeeze, prompting a wave of giggles and farts from Vanille. Fang took a deep breath and let herself relax. Fang kicked off her shoes and let her toes sink into the water around the boat, which had begun to move. The water was thick and sewage-like; it looked like the park just dumped its garbage into the water park; there were pieces of trash bobbing in the dark green water as far as the eye could see.

As they entered the first tunnel, the girls gave a shout; something was sprayed all over them! As they entered a lighted portion of the tunnel, they realized it was chocolate. Vanile got the hint first, and shoved her face into Fang's chest, licking up the calorie-laden fudge that had drenched them both. Soon it was Fang's turn, and Vanille realized why Fang was getting so fat; she ate like a starved piglet! She lapped up the chocolate covering her flabby stomach, cleaning every roll and even her belly button to spotlessness with a deft tongue, release a steady stream of flatulence all the while, rocking the boat. She spent longer on Vanille's breasts, which had become rather hefty for the normally waif-ish redhead. Vanille gave a sharp tug at Fang's potbelly to try and get her to ease up a little. Fang came up from Vanille's chest with a grin. "You've gotten pretty chesty there! I always loved milk chocolate." She gave Vanille a wink. Vanille smiled, blushing. "If it didn't feel so good to take a little pressure off my chest I'd call you a pervert!" Fang laughed, then sniffed the air, bemused.

"Smells like old gym socks!" The lighting of the tunnel had turned a deep scarlet, and the temperature was rising rapidly. Little heart designs and silhouettes of curvy ladies coyly fanning their armpits played across the walls. Fang got the picture fast and was soon basking in the heat like a cow on a summer's day. Vanille hadn't sweat much since she arrived, and at first was a little taken aback by the stench that was emanating from Fang. Pinching her nose, she asked Fang if she was going to shower when they got out. Fang smiled and put her hand around Vanille's waist, playfully poking a finger into Vanille's belly button. "Take a whiff of yourself, then talk!" Vanille raised her arm and took an experimental sniff; she could detect a vaguely sour-sweet odor beginning to develop. "Let yourself sweat it out, believe me, you'll love it!"

Once the girls had passed the sauna tunnel, several dozen boxes of chocolate were dumped into the massive boat from a hatch in the top of a tunnel. Fang sighed at Vanille, who was unwrapping one for her. "No no, silly girl! Watch this!" Fang got up, grabbed an armful of boxes, placed them in her seat, and brought her heft down upon them with a grunt. Her rear end, massive and still slick with sweat, compacted the chocolates and send them flying out of their containers in a thick, taffy-like consistency. Fang got up and waved a chocolate-caramel-nougat-cardboard coated ass in front of Vanille, who was still experimentally sniffing at her armpit, a little more confidently this time. Fang let out a fart, sending Vanille's hair into a dance for a moment. The burst of gas got Vanille's attention however, and the delicious looking snack in front of her kept it.

Fang and Vanille emerged from the tunnel of love with chocolate stained mouths, reeking to high heaven . <BLuuuuurap!> Vanille belched into Fang's mouth as she was about to bite down on one of her last pieces of chocolate. "How much chocolate did you think we ate?" Fang shrugged, fanning herself. "How many saunas did we go through?" Vanille cringed. "We definitely got fatter on this ride! My skirt feels so much tighter!" <Frrrrt!> Fang sighed. "Well we did decide to ride it over and over again for five hours, what did you expect? C'mon, lets go park our fat asses someplace new!" She planted a slobby kiss on Vanille's cheek and gave her pasty, banana-rolled rear end a peppy slap.
