Chapter 2

“I am Inspector Phil McCracken, and I have a warrant to search EVERYTHING in this place,” my older brother Jeff abruptly opened the doorway to the bathroom that we shared with our brothers. He had a shit-eating grin on his face.

My little brothers flanked him on either side. Shaun and Bobby introduced themselves as Seymour Butz and Mike Huntz, respectively. They clearly thought their new names were really clever.

My older sister and I were down on our hands and knees cleaning the bathroom tile. It wasn’t a punishment. Cleaning the bathrooms was part of our weekly chores, but we were still in hot water with our parents and on restriction.

“We can’t afford to get in any more trouble with Mom and Dad, guys – truce, okay? Can you just let us finish cleaning the bathroom, and then we’ll play whatever weird game you want to play?” Lynda asked curtly. She is the oldest and used to be the one who could boss all of us around when Mom and Dad weren’t home.

However, since she got us both placed on restriction – my older brother Jeff has been put in charge, and he definitely enjoyed his new authority.

“No can do, Lynda,” Jeff shook his head from side to side. “This is an FBI matter, and lives are at stake. We have to search the entire premises from top to bottom, and we’ll start with your bottoms. Please stand up and pull your panties down to your ankles – don’t make this any harder than it needs to be,” he grinned wickedly.

My sister sighed in frustration. The guys had been teasing us relentlessly ever since Mom caught her sneaking her boyfriend into the house when she was supposed to be babysitting all of us.

“Don’t you ever get tired of sticking a thermometer in our butts?” she said as she stood up, faced away from the guys, lifted her skirt up, and started to pull her panties down. I joined my big sister.

“No medical emergency here, Lynda Foster – IF that is your real name,” Jeff pretended to be a wary lead investigator. “This is FBI business -Female Butt Inspectors, and we’ve got a hot tip that one of you is carrying around a bomb!”

“The only bomb they have in their asses is from eating one of Mom’s tacos,” Shaun quipped.

“We must take this potential threat seriously, Agent Seymour Butz,” Jeff was half-laughing about the time he said Seymour Butz out loud. The guys were tittering and joking as my sister, and I bent over.

“Skirts completely off, ladies!” my youngest brother Bobby insisted.

“C’mon guys, we have work to do – can’t you just play with Iris and let me finish cleaning the bathroom?” my older sister offered my bare behind like she was trying to make a deal. I glared at my older sister because I definitely didn’t want to be the only one humiliated.

“Nope, everything off,” Shaun confirmed that we’d have to undress completely.

“You just said skirts earlier,” my sister frowned, stood up straight, and began to remove her top. She didn’t wear a bra; she almost never did, but it was the 1970s, and most girls our age didn’t wear bras. I was too flat to need one, anyway.

“I am the lead investigator, and what Agent Mike Huntz MEANT was that this is a strip search – so strip!” Jeff confirmed as Shaun and Bobby emphatically agreed. The boys waited with arms crossed for us to remove our skirts and tops. Once we were naked, they still weren’t satisfied. They even wanted our socks off.

“All this to stick a thermometer up our butts?” Lynda turned around, shook her pretty brown hair, and spread her cheeks. I reluctantly did the same thing – preferring to let my sister do the talking for the two of us.

“I already told you that there is no medical emergency – it’s a strip search,” Jeff held up his finger as he approached us.

“Can you at least wash your hands?” Lynda looked over her shoulder at her little brothers and shot them a disgusted, condescending frown.

“Why? We are just going to get your poopy peanut butter on them,” Bobby giggled.

“I don’t have a poopy butt,” Lynda insisted angrily before seething as Jeff plunged his pointer finger all the way to the knuckle into her ass.

“We’ll see about that,” Jeff grinned.

“You could have at least put some K-Y on your finger,” Lynda frowned as she looked straight ahead and endured the humiliation of being naked and being drafted into our brother’s dirty games.

“What is K-Y?” Jeff giggled.

My sister didn’t have a chance to explain before Shaun plunged his finger into my tight asshole – just the tip. I cringed and made a face in anguish because the biggest thing anyone had ever put up my ass was my mom’s rectal thermometer and the occasional well-lubricated gloved finger of a nurse or doctor.

“Whatever it is, you don’t need it- we are already in,” Shaun decided as he slowly applied pressure to my anus to push the tip of his finger slightly past my anus.

“If you three virgins ever score with a girl other than your sister, you’ll have to learn about K-Y, it’s sex lube. You can buy it at a Pharmacy when you pick up condoms – maybe you will get lucky and meet a girl who can show you how to apply it.”

“What does it do? Burn like Ben-Gay?” Jeff theorized. I quivered at the very thought of the guys lubing me up with Ben-Gay.

“Maybe it fizzles like Alka-Seltzer,” Shaun guessed. I couldn’t imagine my ass fizzing like my butthole had rabies – but it made me blush even harder with shame.

“It probably makes it easier to slide your dick in their ass,” Bobby’s guess was crass but correct.

“I can’t believe little Bobby knows what K-Y is for, and you two dummies think that girls would want you to make their ass burn or fizz,” Lynda said sourly. She clearly wasn’t enjoying what my older brother was doing to her ass. “Stop twisting your finger, please – that hurts!”

“I am searching for the bomb! Lives hang in the balance, Lynda,” my older brother joked. He smacked her butt cheek playfully.

“How come I have to wait to get a turn? It’s not fair,” Bobby whined.

“Unless these two fart sniffers grow an extra turd hole – or you want to ask Mom to play FBI with us – you have to wait, Bobby,” Shaun chuckled. He was slowly penetrating my asshole, and the worst part about it was that I was getting wet. I couldn’t help it – it was an automatic reaction to the situation and the pressure he was exerting.

“Gross, Mom!!” Bobby dramatically acted like he would rather die than even think about it. “The name is Agent Mike Huntz! And don’t mention Mom again!”

“Sorry, Bobby!” Shaun laughed, clearly not taking this game as seriously as his brothers. “There are only two butts and three of us – you are the youngest brother – so you get last dibs!”

I felt like a Pinball machine that the boys were arguing overusing and not a human being – my spine tingled as a fresh wave of humiliation washed over me -while my younger brother tickled my butthole and wormed his finger further into my clenched asshole.

“Let me get Iris warmed up for you – it’s like trying to stick a candle through a hole designed for a match stick. How do turds even pass out of your asshole, Iris?”

Once again, a second wave of humiliation washed over me as the guys theorized that my ass was so tight I must be constipated all the time.

“Iris doesn’t poop any turds; that’s why she always looks so constipated,” Jeff laughed at me. Everyone had a good laugh – even my older sister. We were largely in this predicament together, but my older sister still seemed to enjoy my humiliation at times. She said that I brought it on myself and seemed like a glutton for humiliation, but I disagreed.

“If you want to watch me go poop, all you have to do is ask,” I frowned as I attempted to stand up for myself.

“We don’t have to ask. Mom said we can come to the bathroom anytime we like,” Bobby countered. That much was true.

One of these days, you’re going to push us too far, and Dad is going to smack you back into next week, Jeff. Have your fun,” my sister surrendered her asshole to my brother and let him play.

I did my best to relax my sphincter and do the same thing.

“Dad knows that Mom said we can walk in and check on you,” Jeff reminded her, slapping her butt lightly and adding that was just how the cookie crumbled for us. “and call me Inspector Phil McCracken!”

A few days earlier:

“You got my seat all wet with your pussy drool,” my older brother Jeff pointed a finger angrily at me. I was mortified. He was able to get away with talking to me like that at the dining room table in front of my parents because my sister and I were on restriction, and my mom doted on my brothers. She always favored them over the girls of the family.

Even before we were on restriction, If they teased us and we complained, she’d tell us to grow thicker skin and just suck it up.

“No, I didn’t,” I blushed and pouted – my face red with humiliation. I was wet, and I couldn’t help it. It was like my pussy had a mind of its own, and it wanted to betray me and make me look like a horny little girl whenever it had the chance.

“Jeff, I put you in charge of the others to REDUCE the drama and stress, not to add to it,” My mother sighed as she turned around from the stove to scold both of us. “I am trying to make breakfast, and I really can’t play referee while you and your sisters have disagreements.”

My father was quiet, as he often was – drinking his coffee and reading his morning paper. He saw everything but said nothing. He delegated the small stuff to my mother, and my mother delegated it to my older brother Jeff.

Mom frowned at us and told us to stand up and face her – I did as instructed and placed my hands behind my back, and so did Lynda.

Lynda is the eldest of all of my siblings, and she used to be mom’s enforcer. She was the undisputed person in charge when my parents went out and had been since we were all little. However, she had recently fallen from grace.

My mom hadn’t established an official pecking order or designated Jeff as in charge. She didn’t have any posted house rules, but she expected certain things, and one of them was that we girls wore panties under their skirts.

“Just because you sprouted titties and pubes last year, you started acting like you are an adult, Lynda. I have news for you, you aren’t!” Mom lectured my sister about being too big for her britches. It was a lecture we heard almost every morning since my sister, and she had a falling out. “You started inviting boys over to the house, smoking pot, and running around without panties, and now I can’t trust you.”

“I am sorry, Mom! I’ll do whatever it takes to make it up,” Lynda assured my mother.

“I’ve heard that one before,” my mom scoffed. “Jeff, you are the next oldest in the house, and your older sister Lynda just can’t be trusted to watch over you. I don’t mind if you tease each other, but show me how you are performing their panty check?”

My mother had initially started panty checks a few weeks ago. She would make us quickly flip up our skirts to ensure we had on panties before school. She’d sometimes do it after school, but she was rarely home when we got off the bus. It was mostly a once-a-day thing that only took a second. It was humiliating, but it wasn’t degrading and drawn out.

About a week ago, Lynda decided to get cute and had her panties pulled up in her ass-crack under a very short skirt. I am not sure if she was testing my mom’s patience or if she did it by accident, but after that, Mom made us turn around and show her front and back.

It went from a few seconds to a good long look and a warning to behave ourselves and not be dirty girls at school.

“It’s the same way you are doing it,” Jeff made us pull up our skirts and hold them up – to expose our white cotton panties to everyone in the kitchen. “I just make them pull their panties down so we can see if they are shaving their pussies.”

That was another recent humiliation. My mom had insisted that I shave up to my waist when she noticed that I had sprouted pubic hair a few weeks ago. Lynda laughed it off and told me that when I finally grew boobs and sprouted into a woman, our Mother would let me groom myself however I wanted.

After Mom caught my sister fucking around with her boyfriend, Billy Parker, while she was supposed to be watching me, I guess the two of them got into an argument. My sister said some choice words to her – practically daring our Mom to put her on restriction.

Lynda learned that it’s best not to try to bluff my mother into backing down when she got herself placed on restriction. She was usually the one in charge when my parents were gone – but that was over. Mom insisted that Lynda stay home and ask permission to go anywhere. Lynda’s foul-mouthed escalations only made it worse, and Mom made her start shaving everything below the waist – even her pussy.

She said she wanted me to shave because I was too young to have so much pubic hair, but for Lynda, it was obviously a humiliating punishment. The fact that my brothers knew I had to shave my pussy bald made it feel like a humiliating punishment to me as well.

So now, Lynda and I have to shave our pussies daily, and Mom started checking to make sure that we were smooth and hairless – but she got busy, and somehow, Jeff talked her into letting him be the one to make sure we had panties on. I don’t think he ever asked if he should be the one to check if we shaved or not. He just started doing it, but Mom didn’t stop him.

“Okay, I am fine with you doing a little panty inspection at the table. The girls seem intent on showing everyone else what they have under their skirts – so they may as well show their brothers. I am just asking why can’t the girls just flip their panties down quickly. Why do you make them take their panties all the way down to their ankles and sit down at the table?” my mom asked Jeff. She arched her eyebrows because even she felt that was excessive.

“You wanted them shaved, and they could miss a spot. We look them over and make sure there isn’t any stubble or stray hairs sticking out of the sides of their little clams!” Jeff fired back – like it was an imposition for him to admire our pussies every morning.
