Upon a suggestion from one of the users in the subreddit. Hope you enjoy this story!

\------------- Characters:

\-**Anon**: He's a guy in his early 20s, dark hair, very tall, almost two meters and very fit although a bit goofy and clumsy. Especially when around his step-sister at home. His biggest hobbies are hitting the gym and annoying his step-sis when she's at home by picking on her because of her body.

\-**Liz**: Anon's step-sister, she's 19 and she's a natural blondie with hazel eyes. She's the complete opposite of her step-brother as she's really short, about 150cm and very petite body. She tries to avoid Anon at all cost, even by staying in her room the entire day if necessary.

\-**Veronica**: Liz's mother and Anon's step-mother. Like her daughter she's also a natural blonde with hazel eyes, you could say she's the carbon copy of her although a bit older as she's in her late forties. She manages the household and will soon find out that her past will be needed to help Liz.

\-------------------------

Life was average for Liz, except for her goofy step-brother pulling all sorts of weird pranks on her. Like that one time he hid all her clothes while she was showering and she had to run through the house chasing him with just a small towel covering her privates.

Sadly for her, today Anon had in mind another one of his silly pranks. He knew she was getting ready to go a party that night and he knew she'd need her high heels. Liz planned the outfit very well and Anon knew, so he had the brilliant idea of hiding one of the shoes in an unthinkable place. The cellar downstairs behind the wine bottles they had. A place Liz would never think of.

As she was getting dressed to go out, Liz noticed that there was only one of her shoes in the place she prepared them. She immediately yelled for Anon's name and started shouting "WHERE DID YOU HIDE MY SHOE YOU PRICK". Anon was already snickering in his room, locked in and just playing videogames and having a laugh with the boys.

Liz ended up having to wear a different pair of shoes for the party, some that didn't match her outfit at all, of course she was unhappy with that and the day after decided it was time for revenge. She didn't know what kind of revenge to get as he was already the master of pranks so they wouldn't work on him, so she figured out and thought to herself "Mother knows best."

Later that day, she walked in the living room where her mother was sitting down watching TV. She didn't know how or what to ask and just called Veronica to attention with a simple "Mom, can I ask you something?" to which Veronica just smiled and replied "Sure honey, how can mom help you?"

Liz started explaining that for the last couple days Anon's pranks have been really annoying and she'd like to get some sort of revenge on him, but she doesn't want to play jokes on him as she wants him to learn his lesson and hopefully stop bullying her with his dumb pranks.

Veronica smiled and just told her "Aww Lizzie, I know how you feel and I know just the perfect solution for it" and as she said that, she raised her right hand and with a swift movement of her fingers she flicked the air. "Just like that." she then added. Liz was unsure of what that meant.

"What is that supposed to mean?" She asked. To which her mother simply replied "His balls, honey. Lure him into something and flick his testicles, that will teach him a lesson." Liz was pretty shocked at her mother's words but somehow she was kind of sold on the idea and curious of what would happen.

That night, she was getting ready again for a shower and decided that it could be a good bait for Anon, he'd try to steal and hide her clothes again. She'd catch him red handed and in a perfect position to act out her plan. So she smiled and just proceeded as usual. She undressed and left the dirty clothes outside the bathroom.

Liz got into the bathroom, and left the door slightly open to hear her step-bro's footsteps. Anon was waiting in his room for the water to be open for a minute or so, that was usually a sign of Liz being under the water and unable to stop him. Liz knew this and opened the water but didn't get in the shower.

Anon slowly walked to the bathroom door and opened it, only to find his topless step-sister waiting for him. Liz quickly bent down and with her hands ***flick*** ***flick*** with an incredible accuracy she hit both his left and right ball, causing him to wince in pain and almost fall over. He quickly got up, with his hands still covering his sore testicles and ran back to his room. Liz knew he won that time.

She was pretty proud of herself and then she proceeded with the shower, this time without having to worry about clothes or anything as Anon was mending his jewels in his room. She then got dressed and went to sleep.

The next morning Liz went to her mother again to explain how it went. They were both in the kitchen having breakfast as Liz brought up the topic. "You know mom, the thing you told me yesterday, it worked very well". Veronica a bit confused asked "You mean the thing I told you about your step-brother?" to which Liz simply nodded and smirked.

Veronica was surprised but proud of her daughter at the same time. "I'm glad you still listen to your mother's advice. Good girl. Tell me now, how was it?" She then asked and Liz explained how she planned the whole thing. "...and just like that..." she flicked the air with her hands, mimicking what she did the previous night.

"I'm sure he won't be pulling any pranks on you anytime soon... now tell me... would you be down to get more revenge on Anon but with my help this time?" Veronica asked. Liz didn't know what to say about that and was just surprised to hear her mother ask about it. But then she thought about all the pranks that Anon pulled on her and told her mom "Yeah let's do it."

Liz and Veronica sat there for half an hour theorycrafting a plan and Veronica came up with a very simple yet very smart one. "Well, I'll just call him and tell I need some help down in the cellar, once he's there I'll tell him to fix a screw underneath that bench we have down there, as he lays down for it, I'll tie his ankles to the floor hooks. For his arms we'll figure out something. Sounds good?"

Liz agreed as she didn't have a better idea. Her mother then told her "Oh I forgot, make sure you wear the high heels he hid from you last time, I have something in mind." Liz nodded and went to prepare for that. Veronica also went to her bedroom to get ready for it, she had the chance to turn her daughter into a ballbuster and was not going to miss it. She got dressed and grabbed the ropes.

Later that day, Veronica met up in the cellar with her daughter and decided to proceed as planned. She started calling Anon, that was chilling in the living room. "Anon... Anon can you come down the cellar to help me with something?" She said, as she was waving Liz to hide in a corner.

Anon sighed and went to the cellar. "What is it?" he then asked. Veronica just explained that the bench that held the bottles had a loose screw at the bottom of it and she was not tall enough to reach it. "That's why I called you" she then added. Anon just nodded and laid down to check the screw.

Now that he was down, Veronica quickly tied his ankles to the floor hooks. Anon was caught by surprised "Hey what the hell is going on?" he tried to protest and buckle free, but sadly for him Veronica's knots were quite resilient and tight. "We're just gonna have some fun now." Veronica added, mocking Anon that was tied on the floor. "We??" asked Anon.

"Yes, me and Liz. I don't know if this will be fun for you" She added smirking. Shortly after Liz came out of the corner she was hiding in and turned on the big lights. "I know you've been pulling pranks on my daughter. She came to me for guidance and this is it."

Liz was standing there with a rope in her hands, looking devilishly at Anon. "Tie his hands honey" ordered her mother. Anon tried to protest but he was quickly interrupted by Veronica putting her boot on his crotch. "Shut up and don't try to fight back or you'll say goodbye to these" she said, sounding so commanding it almost made Liz feel threatened too.

Anon stopped talking and let Liz just tie his hands. "Good, now he's all ours. I'll tell you what to do now" Veronica said. Liz was standing at attention waiting for her mother's orders. "Pull down his shorts and underwear." She said. Liz didn't really want to and replied "Do I really have to?" Her mother quickly stopped her. "Yes, do as I say, trust me"

She didn't want to disobey her mother, after all she agreed to her plan. And proceeded like instructed. Liz pulled down her step-bro's shorts and underwear, revealing his penis but most importantly his testicles. Two big orbs that looked like perfect toys to Veronica.

Veronica then sat on a chair and started giving instructions to her daughter. "Now, start slapping his testicles, like you really mean it." Anon started to protest again but Liz proceeded as instructed. ***slap*** ***slap*** ***slap*** ***slap*** ***slap*** Slap after slap Anon's moans were getting louder and he was begging them to stop.

"Good, now grab one with each hand, and start squeezing as if they were lemons." Veronica instructed. Liz simply obeyed and grabbed one testicle in each hand and started squeezing, she didn't know how much force to put in and started squeezing lightly. Veronica noticed "Harder Lizzie, we want to get some good juice out of those lemons, not just a few drops, squeeze as hard as you can"

Liz started squeezing with all her might, Anon started moaning and screaming in pain, his testicles were overfilling his step-sister's tiny hands but she causing him a lot of pain. She kept squeezing and pumping his balls for a good ten minutes, Anon was on the verge of crying.

"Stop squeezing now Lizzie." Veronica instructed before adding "You see Liz, I made you wear the high heels he hid from you to teach him a very important lesson, a girl's shoes are very important objects, some that silly men don't have to mess with. We want Anon to understand this now, don't we?" She asked. To which Liz nodded.

"Good, now then, stand up and put one of your pointy heels on one of his soft testicles." Liz got up, and proceeded as instructed. Then looked up at her mother waiting for the next order. "Now push down and make him understand how important your shoes are" Veronica said, smirking.

Liz smiled back and started putting her weight on her right heel, that was standing on Anon's right testicle. He begged her to stop but Veronica just said "Ignore him, keep going honey you're doing great". Liz kept adding more and more weight on her heel, feeling the testicle compressing under her pointy heel.

"Now the other one aswell, we don't want it to feel left out" Veronica said, mocking Anon. Liz proceeded as instructed and placed her right heel on his left testicle and did the same process as before. Slowly putting weight on the testicle, making it compress under her pointy heel but not enough to pierce it. Anon was feeling hell on earth.

"Enough Lizzie, don't want to ruin all the fun by breaking one just yet." Veronica stopped Liz and got up from her chair. She walked near her daughter and said "How about a challenge?" Liz was surprised and interested and said "I'm all ears". Veronica smiled and explained "We both start flicking one testicle each, I'll let you choose which one, first one to get tired and stop loses. Sounds good?" Anon was protesting again but they didn't care at all.

Liz smiled and agreed. She then said "If I can choose, I'll pick the left one, it's the bigger one of the two" Veronica smiled and added smirking "We'll see if it's still the bigger one of the couple after this". They then knelt down and started with the challenge.

***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick***

5 minutes had passed, Veronica said "Still not tired yet?" to which Liz replied with a simple "Nope." and they kept flicking. Anon was yelling in pain, and it was annoying Veronica, that got up quickly, took of her panties and stuffed them into his mouth. "This will keep the volume down for a bit." she said before getting back to the flicking game.

***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick***

15 minutes into it, Veronica still on the same pace but Liz was visibly more tired than her mother and was starting to slow down. "Getting tired honey?" her mother asked giggling "Yeah but that doesn't mean I'm quitting already" Liz admitted. Anon's muffled moans in the background were getting more and more pleading while his testicles were getting more and more red as time went on.

***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick***

20 minutes in and Liz decided to stop "Oh god my hands are so tired, I think I'm gonna need some ice" she said. Veronica just giggled and said "20 minutes for a first timer are not that bad honey, good job, I'm proud of you." But she didn't stop, she kept flicking and flicking Anon's right testicle.

***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick*** ***flick***

30 minutes into the flicking and Veronica's pace was still up, like a metronome. Liz was admiring her mother's skills almost unable to hear Anon's yelps and moans in the background. His right testicle was now a very bright red and with a few final flicks, Veronica declared her job done. "Now let's see who was right." she added.

Veronica gave a quick look at Anon's scrotum "See Lizzie, I told you now his right testicle is the bigger one of the two" she said, mocking both Anon and Liz. And she was right, Anon's right testicle was almost three times the size of his left one, swollen from all the extra flicks it took.

Liz was kind of shocked but somehow she really enjoyed this. She complimented her mother "You surely know what you're doing. I have a lot to learn I guess." Liz added. Veronica thanked her and smiled before adding "And I'll keep teaching you all the secrets honey" giving a final slap to Anon's testicles "We even have our plaything to practice on" she added.

Liz had found a new hobby and it was a shared thing with her mother, she couldn't be happier and couldn't wait for her next practice session with her mom.
