“It won’t stop!” Akane screamed in her head. Everyone and everything seemed to be out to make her feel as horny as possible, whether it was Ranma and Shampoo doing it inside of her or Kasumi handing her with such expertise. Her sister was eating her so well while also never keeping her hands out of the action. She was rubbing her thighs and squeezing at her belly as much as she could. Feeling her nails scratch and dig into her fat or the sensual touch around her often wide spread legs along with the gentle but precise lapping she was receiving, it was like Kasumi instinctively knew which buttons to press to make her baby sister go wild. Akane couldn’t resist wondering just how much experience she had with Nibiki, and that thought made her feel both like crying and want to smile at the same time. When was this going to end?

Almost every lap made Kasumi moan over how tasty it was. Akane had a very yummy pussy, and it was oozing so much cum that Kasumi couldn’t believe. More and more sweet nectar kept it oozing onto her tongue, keeping her slurping down constantly. Her wet sucking was growing louder, making Akane beg for ear plugs.

At one point, Kasumi felt her try to close her legs around her to force her out, but in Akane’s weakened state, she was able to push her legs even further apart than before. The fatter of the two wailed as her legs were spread so wide. She didn’t want to be a pervert!

“Give up Akane. Just enjoy yourself.” A vein throbbed in Kasumi’s head as she thought that about her sister. Pulling her tongue back momentarily, she wrapped her lips around her clit and sucked hard, getting an ear splitting scream from Akane, and yet with all that, still her sister refused to orgasm. If anything, Kasumi did have to give her sister credit for holding back her orgasm, but she was doing it for all the wrong reasons. As she continued to breathe so hard that it sounded like she was giving birth, Kasumi decided to really push up her game.

She actually nibbled on the clit, getting more wails from her whale of a sister, but all Kasumi focused on was the throbbing, hot, delicious cunt before. She buried her face deeply into the hole, sinking up to her nose and letting the weight of the belly keep her in place. Her lapping grew rougher and it sounded like she had a giant popsicle down there. Kasumi grunted and her head bobbed with every lap, making it look like she was humping her sister with her face. She wasn’t coming out until Akane started acting like a mature lady.

“NO!!!!” said immature lady now successfully got her legs wrapped around Kasumi, ready to pry her out with all the strength she had, but when Akane clenched so hard, Kasumi only felt a crushing pain for a second before she felt herself plunging into a much hotter and tighter spot.

The shriek could be heard several blocks down as Akane felt her pussy spreading over something even bigger than Ranma’s cock. Everything hit her so hard all at once, and the orgasm just shot through her like a jolt. Only some cum leaked out of her though, as the distraught land whale could feel plenty still rumbling and boiling inside her belly. “What’s happening???!!!!” she demanded to know, and a familiar slurping after several loud gulps clued her in. Suddenly, Akane knew that if she could see past her gut, it would still be hard to see all of Kasumi, and when her sister guzzled it all down vigorously and with a happy smile, a lap at the hyper sensitive birth canal caused it to throb and convulse harder than ever before. Suddenly acting like her big mouth, Akane’s second lips gulped Kasumi down to her chest in one gulp!

“NOOOO!!!!!!!” Akane’s massive gut quaked more with her new cries; the only good thing for her right now was that her super stretchy throat was impervious to getting sore. She could feel her wetly squelching and throbbing around her sister’s body, almost like it was chewing her all the way down. She wanted to push her out, but her body was practically immobilized from the hormone overload. She felt her sister’s chest squishing into the bottom of her birth canal as she slid in so effortlessly from all the slickness. If that wasn’t bad enough, this was the next thing Akane heard from inside her “WHEE!”

Kasumi laughed like a little girl at a carnival as she was taken on the sexiest ride of her life. Akane’s insides were like an amazing waterslide and the overwhelming aroma of cum all around her kept her feeling so good, and some even splashed up onto her, giving her more to drink. By the time she was done, she could be dealing with water weight, or in this case, cum weight. Still, as she let the cunt do all the work, she couldn’t help but wonder something, and called out “How does it look from your end Akane?”

“FAT!!!!” she barked with so much anger, watching her belly bloat out and become even more grossly huge. It made her absolutely sick, but someone inside was nice enough to point out “You already super fat.”

“SHUT UP!!!!” Akane’s rage was only quelled by feeling the biggest part of her sister starting to enter her. Those super wide hips were just the first indication for all that junk in her trunk that was coming in. Kasumi felt her journey starting to slow down, and she looked back, blushing with much embarrassment “Oh my, I hope I don’t get stuck.” Her face kept getting redder and redder; some days it was just a pain to have such a large bottom.

Akane panted harder and harder, unable to believe that her cunt was really doing it. She felt it slowly but surely wrap around Kasumi’s hips and knew that the fat ass was sure to follow. Was every hole of hers always willing to gorge? Was she doomed to get humongous from every orifice?!
