one week later

So about a week since my discovery of the app and our subsequent fun field trip has passed. You might be thinking that at this point I would have used this app to indulge in all manners of depravities. Not so. As tempting as it may be to mess with Ben all day every day I am a responsible big sister.

We did have a talk. I won't bore you with the contents of it, but basically it was concluded that I wouldn't use the app unless it was an emergency. Again, I had to consider what psychological effects all of this might have on Ben.

And so a remarkably ordinary week passed.

It wasn't until Friday when I got a call from the sisters. They wanted to meet up. Ben was really eager to see them, for some reason. But he didn't want to go out, again for some reason. So I just invited them for a casual get together at our home.

…

“Big Bro! I missed you!” Peggy laughed and hugged Ben.

Ben smiled and patted her head. “I guess I missed you too, for some reason.”

Peggy grinned. “Oh? So that's how you look when you wear normal clothes? I think I prefer you the other way.”

“Pardon the intrusion.”

And so we found ourselves in the living room discussing how my brother wet his pants at the zoo.

“It appears you have recovered quite favorably. If possible I would like to conduct an interview about your experience.” Alyssa said while whipping out a pen and notebook.

“Well, I suppose I have.” Ben smiled. “And no, I will not give you an interview.”

“That is most unfortunate. I would prefer to have a voluntarily subject.”

“Alyssa, please...” Angelica sighed. “We came here to apologize remember?”

Ben shook is head. “No, no its fine. This really was just all the fault of my dumb Sister.”

“Sister?” Alyssa cocked her head.

Ben, you idiot!

“Oh, you are in a roleplay right now?” Angelica coughed. “I suppose Ben is the bratty little brother, who needs to be punished by his older sister...”

Well, that's kinda our normal relationship, so I just rolled with it.

“uwaa..” Peggy grinned. “Does that mean you are about to punish him? He did just call you dumb, after all...”

“H-hey! Stop it. Nobody is going to punish me!”

“I assume the reason you invited us was so we could partake in all of this?” Alyssa began scribbling something. “We never witnessed you actually disciplining Ben at the Zoo. So this would be most illuminating.”

Ben gave me a look that was very clear: Don't you dare.

He really should know me better.

“Ben...get on my lap. Butt up.”

“No...i will not! Ugh..stop this.”

The Sisters looked on in astonishment as Ben crawled up and lay across my lap.

Jeans or no Jeans?

“Stop this! Dumb cunt! I'm not some small kid!”

Definitely no Jeans.

“Ben, you are forbidden to speak. I casually unzipped his Trousers and exposed his black Boxershorts. I gave them a little pat. “Since we are having guests over, I will allow you to keep them on this time.”

“MMMMMMmmmmmpffff...”

Since we are having 3 Guests, lets make it 30 Slaps. “I want you to count them loudly. You aren't allowed to say anything else. Is that understood?”

“Mmmmmpffff...”

My Hand rose and fell down with magnificent ****. Ben cried out.

“One!”

slap

“Two!”

slap

“Three!”

I must admit my technique was still quite good. Those three years spend as captain of the Volleyballclub certainly came in handy. Since it was only 30 slaps and Ben still had his Underwear on, I also didn't think it was necessary to hold back.

"I like you to thank me after each slap."

slap

"Eight! Thank you, sis!

slap

"agh.....Nine! Thank you, sis"

slap

"T-ten....thank you...sis..."

...

..

.

SLAP!

“Thirty...t..ugh....t-thank....you...big...sis” Ben finally proclaimed, barely able to withhold his tears.

“You may speak again. Have you learned your lesson?”

“Ughh....yes...” Ben rubbed his butt.

“Apologize properly!”

“I am sorry for calling you dumb, Sis.”

“Good” I nodded and allowed Ben to leave me lap.

As expected the Sisters where completely silent during the whole spectacle. At least Peggy's face was also just as red as Ben's backside.

“That was quite the display.” Angelica composed herself first. “This really has me convinced that we had the right idea after all.”

“I concur. I think this will serve quite nicely as an apology.”

Both Ben and me looked at each other in confusion. “What are you talking about?”

“Well, at the Zoo we really didn't act very professional and we didn't gave Ben the treatment he deserved. As such we would like a repeat.”

“Uh...what!”

“This time we do it properly Big Bro, oh this will be so much fun!”

“Like hell you will!” Ben cried out. “And what kind of crazy logic is that? Just give me a Cake or something!”

“Ben”, Angelica sighed. “There is nothing wrong with being honest with yourself. We did consider that Rina might just drag you along into her urges...”

“Oi, oi”

“But the way you are acting makes it very clear how much you enjoy...well humiliation. Even so, with Rina alone there is a limit what you can do right? Hence we offer our support.”

“I did plenty of calculations. I believe with proper methods I can increase your humiliation by 70%, hence greatly increasing your pleasure.”

“I don't really get it, but we will do more fun things with big bro, right? Yay!”

“Siiis.” Ben gave me another very clear look. “I think we are having a very big misunderstanding here. Would you be so kind to clear that up?”

I coughed. “Would you excuse us for a second? I need to discuss this with my boyfriend.”

I dragged Ben into the kitchen.

"Your butt feeling ok?"

"My butt is not the issue here!" Ben grumbled. "You have to clear this up."

“Ben...we kinda have to do this.”

“What no! That is out of the question!”

“How else are we going to explain your weird behavior?”

“M-my weird behavior! This is all your fault!”

“Well...lets not play the blame game here, ok? It is what it is.”

“Like hell it is!” Ben stubbornly crossed his arms. “There is a very easy way out of this. Just tell them about the App!”

“But Ben.” I sighed. “What I did to you was kinda criminal you know?”

“Uh...”

“Forcing my own brother to publicly humiliate himself. This would probably count as domestic ****. I could look at 5 years in prison. I do know my stuff here, I am a law student after all.”

“W-What kind of ass backwards logic is this?”

“You wouldn't send your own sister to jail, would you?” I looked at him with big, pleading eyes.

“You can't be serious...”

“Just play along for one last time, pleaaase? I am sure we can figure out something afterwards.”

Ben let out a deep sigh. “You are so doing this on purpose. But fine, just one last time.”

“Thank you Ben.” I hugged him.

…

Afterwards Ben was send to his room, so as not spoil the surprise for what we had in store for him.

“It took a lot of convincing, but he is on board now.”

“Excellent, I think this will be very exciting for all of us.”

“So, my ladies. I assume correctly you have already some sort of plan figured out?”

The sisters nodded eagerly.
