Part 2

“What’s wrong Vi?” Dash asked his sister during one of their now frequent ‘training’ sessions.

“Nothing,” Violet said distracted.

Dash didn’t believe that but let it go for the moment. He was having too much fun with Violet’s new trick to stop and pry into her life.

Violet had realized her power didn’t just have an on and off setting, but it could be partially activated. Violet had gotten so good at the trick she barely needed to concentrate on it. She just turned her lower body partially transparent as Dash trained her ass while she thought about what she could do about the Jana problem.

Dash inserted his cock slowly again for the umpteenth time, never getting tired of literally seeing his cock traveling through Violet’s ass, her walls hugging him tightly and his cock straightening her insides out. He ran his fingers over her partially visible skin wondering why he hadn’t been the one to think of this first. Every thrust let him see how his cock pushed through her meat as her body gave way to him.

But part way through the training, Dash’s curiosity got the better of him and he started wondering why Vi was so distracted; it was like she was hardly paying him any attention. So Dash tried his own trick. He started concentrating his speed in only part of his body and made his cock begin vibrating. But even with her pussy lips quivering from the vibration, Vi didn’t say anything. So Dash turned it up more and more until he was practically like a vibrator or two on the highest setting inside Vi’s asshole. Like that, it usually didn’t take long before Violet was screaming and cumming on him.

Violet bit her lip and began masturbating, but it was unenthusiastic and lifeless and she soon pushed Dash away and asked him to stop.

“Seriously what’s wrong? You love it when I go Hitachi mode.”

“Not today Dash. If you’re gonna train my ass, then no vibrating. I’ve got too much on my mind.”

Dash shrugged and speared himself back into her. “Like what? I’m all ears.”

“You wouldn’t care.”

“OK, you got me there. But you’re acting weird so I promise to this time.”

Violet gave him a measuring look as he kept pumping into her, her body and tits bouncing with every thrust. She sighed and explained. “So there’s this guy at school that I like. Mom gave me some great advice so everything was going great with him right?”

Dash was starting to regret listening, but soldiered through.

“But, there’s this other girl in my class, Jana, that’s started getting interested in him too even though I was interested way before her and she knew that. Now she’s spending all this time with him and I don’t know what to do. I think he might be liking her more than me now.”

Dash made some noises to show he was listening but otherwise didn’t add anything.

“Ugh,” Violet groaned. “I’d give anything to see her mess it up with him.”

And that’s when Dash got an idea.

“Hey Vi, maybe I could actually help.”

Violet eyed her brother. “How?” she asked.

“Iunno, maybe I could embarrass her in public or something? I could make her wear something stupid, or ruin her makeup, whatever you wanted.”

Violet smiled at the idea, it definitely appealed to her. With Dash’s help, there was no end to the things she could do to Jana. “We can’t though,” she eventually said deflating. “We’re not supposed to use our powers in public. If mom finds out, she’ll kill us.”

“Mom doesn’t need to find out though,” Dash said. “I’d do it so fast no one would even notice a thing. They’d never be able to figure out it was me. Seriously, don’t you wanna screw with this Jana girl?”

Violet chewed on her lip, thinking about it and weighing things up. It was risky and could get them in trouble, but if it meant ruining Jana’s chances, then maybe that was worth it. Violet nodded to herself. “Fine, let’s do it.”

Dash smiled. “Yes! That’s what I’m talking about it. Now, about your end of the deal,” Dash said still smiling. “I was thinking you could help me convince mom to do some stuff.”

“Wait what? I thought you were just offering to help me!” Violet cried indignantly.

“Hey, you said and I quote, ‘I’d give anything to see her mess it up with him.’”

“That’s just a saying though.”

Dash threw up his hands. “Then deal with Jana yourself.”

Violet mulled it over a second before giving in. “Fine, what do you want?” Violet asked, narrowing her eyes at Dash.

“Weeeeell, I was kiiiiinda hoping to watch you eat stuff from mom’s asshole.”

“What? Ew, Dash!”

“I don’t mean anything gross, just a little bit of my cum and maybe some food?”

“Still ew.”

“Well if you won’t-“

“I didn’t say I won’t, I’m just complaining OK? I’m allowed to complain.” Violet sighed. “Fine, we’ve got a deal. But you have to deliver on your end first before I do anything alright?”

“Just give me the word,” Dash said grinning ear from ear.

~

After some malicious planning and no little cackling, Violet sicced her brother on Jana and the results were better than she could’ve hoped. Violet came home that day practically skipping in. She twirled around and pumped both fists into the air before she fell back onto her bed, giggling into the pillow. She was interrupted from her happy memories of Jana being humiliated when her brother suddenly appeared in her room with a gust of wind.

Violet threw her pillow at Dash. “Can’t you just let me enjoy this for a moment?”

“Hey, enjoy it as much as you want in your own time. Now it’s time to help me.”

Violet groaned as she lifted herself up. “Fine, a deal’s a deal. What did you want to see me do with mom? Besides eating your cum from her butt.”

Dash couldn’t stop smiling. “Well lots of ass to mouth obviously.”

“Obviously,” Violet repeated sarcastically.

“Well, besides those, I was thinking you would eat breakfast from her ass. I know mom can change her body’s shape, so I really wanted to see her reshape her asshole into a bowl or something you can pour milk into. But you know how she is with using her powers around us. If I asked, she’d never agree.”

Violet listened to the request with growing confusion. “Such a weirdo. Where do you even get these ideas?” Violet asked, shaking her head.

Dash ignored her and just pressed on. “So, how are you gonna help me convince her?”

Violet shrugged. “I’ll try just asking her first.”

“What?” Dash said annoyed. “I told you, that’s not gonna work.”

Violet scoffed. “Maybe not for you; but I’ve never bugged mom for anything and I’m a straight A student. I’ve got like a million brownie points saved up. Maybe if you didn’t get in so much trouble, you could try just asking too?”

“Whatever, but if that doesn’t work, and it probably won’t, you still have to keep trying.”

“Yeah, yeah,” Violet said, brushing him off.

~

Dash was caught between wanting to be annoyed it was so easy for Violet and just happy she had convinced mom at all.

“Dash, I’ve got no idea what you said to convince your sister to help with this little stunt, but you better show her some appreciation mister,” Helen said as she pulled down her pants.

“I already did! I helped her with some school stuff first.”

Helen sounded surprised. “You helped her with some school stuff? That’s what that was?”

“Yeah, he did,” Violet said unsteadily, not having gone into the details with her mom. She got down onto her knees next to Dash.

“Who are you two and what have you done with my children?” Helen said as she laid her body over the arm of the couch, presenting Dash with her ass. Violet then laid her face against her mom’s cheek and stuck out her tongue, letting the saliva drip from the tip onto Helen’s ass, obeying the directions Dash had given her. He’d given her so many instructions, she felt like he was definitely getting the better end of the deal.

The sight of Helen’s ass and his sister’s face resting against it, mouth wet, open and inviting was enough to get him instantly hard. Dash quickly worked himself inside Helen’s asshole and began vibrating with his power. He usually loved doing it with Violet and Helen since it made everything feel better, but it came with a big downside; his cock would spasm around inside them so wildly that they’d loosen up too much, too fast.

That wouldn’t have been an issue with Helen, if it weren’t for the fact she was so intent on using her powers as rarely as possible around the kids. But today was different, today Violet had convinced her mom to use her powers for Dash.

As Dash started vibrating, he felt something entirely new. Helen started using her powers too to constantly tighten herself around him, contouring her asshole to perfectly accept his cock, sculpting her own insides to hug and squeeze Dash in just the right ways and even changing her own texture constantly so that every pump into her felt like he was fucking something different and delicious. She was too good to be new at this Dash thought suspiciously. With Helen finally using her powers with him, no matter what he did, he wouldn’t wear her out. So he took advantage of that as much as he could.

Every so often when he felt like it, Dash would pull out and plunge directly down Violet’s mouth and throat, straight from Helen’s asshole. With her face resting against Helen’s ass, the two holes were so close Dash could easily double dip constantly. Dash slowed down and savored the sight of leisurely pulling his wet cock out of Helen’s ass - ropes of spit and juice still dangling from his cockhead to her ass - before aiming it at Violet and sliding the dirty cock over her tongue and into her throat. A few seconds of throat fucking was all it took to completely drench his cock in her spit. Pulling out, Dash wiped his soaking cock over Violet’s face. She looked annoyed and like she wanted to say something, but she remembered her instructions and just kept her mouth open no matter what.

When he went back to Helen’s ass, Dash was vibrating and pumping her so fast it made one cock feel like three for Helen. But compared to what Bob usually did to her, she managed to relax enough to focus on a book she’d brought to keep herself busy while Dash and Violet used her. She did briefly wonder what Dash had done to get Violet onboard with this since it didn’t seem like Violet’s type of thing, but she was just glad the two were getting along, even if it meant they were bonding over her ass.

Much later when Dash was almost finished with her, he felt his mom go the extra mile and do something he struggled to understand. As he was nearing the edge, he felt the textures and motions inside Helen’s asshole shift again, but this time it almost felt like he was fucking a mouth instead of her ass. Dash knew she was just using her powers but it was the strangest sensation looking down, seeing he was still in her ass but feeling like he was in her throat. What felt like several tongues licked Dash’s shaft up and down even as Helen’s asshole sucked him off. The completely novel and alien sensations were too much. He gripped Helen’s hips and pounded in as he poured his nut into her ass, her asshole literally sucking the cum out of his cock.

Dash held on for dear life as he went through with his final surprise. He wanted to give Violet much more than she bargained for since he had found out he could speed up his bodily functions to produce cum faster. His pushed his powers to the limit and dumped a couple weeks’ worth of cum into Helen’s asshole in the space of a minute. The minute long orgasm was as long as he could manage; any more and he was afraid he’d pass out.

Dash collapsed on Helen’s back, panting hard. “Mom, why didn’t you do that the whole time?” Was the first thing he said dreamily when he finally recovered enough from the ball draining orgasm.

“Hmm?” Helen asked as she looked up from her book. “What thing?”

“You know, making your ass feel like a mouth with tongues and stuff.”

Helen blushed as she realized what Dash was talking about. She’d been so relaxed and engrossed with her book, she’d completely forgotten who was using her ass and just did what she usually did for Bob on muscle memory. It certainly wasn’t a treat she planned on giving Dash since she didn’t want the kids finding out she used her powers at home all the time.

“Oh, that, uhm, I’m not sure honey. Hey Vi, what was that other thing you wanted?” Helen asked, trying to change the subject.

“Mom, it wasn’t my idea,” Violet said defensively, her face still sticky with spit. “It was his, and if he doesn’t get out of the way then I don’t have to do it.”

“I’m moving, I’m moving,” Dash said tiredly. He sluggishly pulled out of Helen and gave Violet some space to work while he watched from the front row.

“This is so unfair,” Violet complained. “You helped me with Jana, one time and now I’ve gotta do all this.”

“Whose Jana?” Helen asked.

“You agreed! You can’t back out now!” Dash said.

Violet grumbled a bit but pulled Helen’s cheeks apart anyway. She reached in four fingers, two on each hand and pulled her mother’s asshole open. Violet’s eyes widened when she saw the enormous anal creampie her brother had dumped there.

“Wh-What? Why is there so much?”

“Is there a lot in there? It felt like a lot,” Helen remarked.

“Yes there’s a lot!” Violet said. “This is like half a cup!”

“What can I say? I’m just that amazing,” Dash said looking smug.

Violet rolled her eyes and buried her face into her mom’s ass, if only to escape that look. She stuck her tongue into the gaping hole and tried to lap up the cum, but only got tiny dribbles doing that.

“I don’t even know how I’m supposed to drink all this,” Violet complained. “I can’t even get at it.”

Dash brightened up. “I know! Be right back!” true to his word, Dash was gone for less than a second before he was back with a straw. “Vi, you can use this,” he said as he dropped the drink straw into Helen’s gaping ass helpfully.

Violet stared at the slightly bobbing drink straw and felt it somehow just made the whole thing worse and even more demeaning. Violet sighed one last time. “Mom, I need a hand keeping you open.”

Helen shifted to holding her book in one hand and used the freed one to reach back and pull herself open. Working together with her mother, Violet pulled from the opposite side and used her spare hand to hold the straw. Wrapping her lips around it, she began sucking out the load of semen.

Dash watched from the sidelines as Violet slurped up his cum through the straw nosily, shifting it around every so often to vacuum up puddles of his cum from here and there. His favorite part was seeing Violet having to gulp down a mouthful of cum once in a while since it was too much to drink in one go. It took five minutes before Violet finished. She covered her mouth with one hand and held her stomach with the other, trying to steady herself.

“Happy?” she asked, clearly disgusted by having to drink so much cum.

Dash nodded rapidly. “Uh huh. You’re the best Vi.”

“So we’re done then?” Violet asked hopefully.

“Well, we’re half way there, but we can do the other stuff tomorrow,” Dash said, not wanting to push his luck.

“So unfair,” Violet repeated.

The next day, Violet had to finish off the other half of her deal; eating from her mom’s ass. At breakfast, the two waited for their mom to finish eating first before they got on with things. And as they waited, the two argued about the best way to position Helen. Dash wanted her to lie flat on her stomach across the breakfast table, but Violet argued that would make things difficult and preferred something like the previous day with Helen bent over something. In the end though, Helen said both ideas were bad and she would instead lie upside down on her shoulders and neck. It would be uncomfortable, but she told them that was how you were supposed to do it.

When asked how she knew that, Helen trailed off and went back to eating.

When she was done, Helen got in position, resting her back against Violet’s crotch, held up between her daughter’s legs as she put her weight against her neck and shoulders on the ground. Violet wrapped her arms around her mom’s thighs and pulled her up further since she didn’t want to lean too low to eat, not realizing it just put even more strain on her mom’s neck and shoulders.

Using her powers, Helen began stretching herself until her asshole became a cavernous space. When Violet tried spreading her mom open, she felt the meat give way softly, more easily than ever. The asshole wasn’t quite like a bowl, being more deep than it was wide, but it’d work.

Dash handed Violet the milk and cereal happily before taking his seat, his own food barely acknowledged. Violet opened up the milk carton and began pouring into her mom’s ass. Helen shifted from the sudden cold pouring into her insides but quickly adjusted. Next came the cereal flakes which didn’t bother her nearly as much.

With Helen’s asshole brimming with milk and cereal, Violet grabbed her spoon and started eating. At first, every spoonful made Violet’s cheek flush from embarrassment, but after a while, it felt less and less weird until it was nothing more than eating breakfast. Violet even got out her phone started browsing the web as she shoveled spoonful after spoonful of food into her mouth.

Dash got out his phone too, but he wasn’t interested in browsing the web. Instead, he recorded everything since he wasn’t sure when he’d ever get his mom and sister to do a repeat performance.

That wasn’t so bad Violet thought as she scooped up the last of the cereal and milk from the bottom of her mom’s asshole.

“You kids done yet?” Helen asked from the floor.

“Mmhmm,” Violet said.

Helen got up and stretched the kinks out of her neck. “Vi, I don’t think you finished your food,” Helen said with a strange expression.

“Hey mom, don’t you always say we shouldn’t waste food?”

“Nice try mister,” Helen said. “Now enough funny business, you guys need to get ready to go.”

~

“So we’re even now right?” Violet asked.

“100%”

Violet let out a breath.

“But if you ever need any other favors, I’m there for you.”

“I think I’m good,” Violet said.
