Mummy & Daddy’s Naughty Diary (Erotica)

Training His Little Sister Slave

Kristen’s always on the look out for a new story.

The Monday after the prom, she smiles, seeing Ben heading into Ms. August’s class during lunch. In Kristen’s imagination (and in reality thanks to her naughty diary), Ben is getting a private lap dance from Ms. August. Kristen has no idea that she gave Ms. August a stripper alter-ego named Ms. July because of her stories.

The girl is oblivious to how she’s rewriting reality around her, just lost in her head.

“Kristen!”

Someone shouting her name is a shock to Kristen. She hardly speaks to anyone anymore. Her best friend Natalie is completely involved with dating Kristen’s older brother. The rest of the family is busy with their lives. At school, she often sneaks off to masturbate and think of new stories.

She frowns at the young man rushing up to her. He’s her age, nineteen. She knows him. “It’s… Derrick, right?”

“Yeah,” he said. He smiled just the way he had when they were kids. He moved away like seven or eight years ago. “My family just moved back. It’s great to see you.”

“Yeah,” she says, smiling at him.

He clears his throat. “Why, you’re looking cute. As cute as I remember you.”

“That’s, um.” She squirms in place. Is he interested in me? That idea is too much for her to handle. “Great seeing you again!”

She darts for the bathroom. She crashes through the door as memories of the past rush through her. He has a little sister. She thinks his sister would be eighteen. Such a perfect age. And Derrick also has a father and mother. Now that Kristen recalls, his mom was always super conservative.

Like she’s too prim and proper, the girl thought. What if she’s hiding something?NôvelDrama.Org holds © this.

What if his mom’s a sex slave to his dad? That idea sizzled in her mind as she slipped into her favorite masturbation stall. And what if Derrick is being trained by his dad to make his little sister into a sex slave because… His parents are secretly brother and sister. Yes, yes. A family tradition of incest.

Kristen has to pen this story.

I sighed as Kristen ran off. I had been so looking forward to reconnecting with her. I had such a crush on her. Now we were back, and what did I say? I called her cute and scared her off. When did Kristen get so skittish?

She was cute, though.

My phone vibrated. I pulled it out and found a text from my mom. “Did you see her? How did she react?”

Mom knew about my crush. She was the only one in the family. If my bratty little sister found out, she would be even more of a tease than normal. I could not stand her. I couldn’t wait to graduate and move out of the house just to get away from Amanda.

“She was very surprised,” I sent carefully.

“It went that bad, huh?” Mom texted. “Just be patient. Don’t stick your foot in your mouth.”

I winced. Too late for that.

Derrick gets a text from his Mom. She’s dressed in her sex slave outfit, a leather corset that lifts her big breasts into a pair of lovely mounds. She has a collar around her neck and a pair of handcuffs around her wrists. It’s clear to Derrick his dad too the picture.

“This is what you have to buy for your sister,” his mom texts him. “It’s time you broke her in. She’s eighteen and needs her big brother to be her Master.”

I smiled at the picture of Mom in her bondage gear. I hadn’t seen her in it in person. I wasn’t allowed in the basement dungeon. Dad was glad to be back in our old house. It had a better dungeon space. He had been busy installing the various hooks in the ceiling.

My sister was such a brat. She needed to be dominated by me. I had been waiting for this moment. For Mom and Dad to agree with it. I had such a crush on my little sister. It was nice seeing Kristen. I didn’t mean for her to misinterpret my words.

Why would I be into such a mousy, nerdy, Plain Jane of a bookworm? No guy could find her attractive. I was all in on my little sister. She was the one who made my dick so hard. I throbbed with the need to just bend her over and fuck her hard.

I would make her squeal in delight. It would be so much fun to do that to her. I would fuck her hard and make her howl out in delight. I would whip her ass. Cuff her. Pierce her nipples. My little sister would be my fucktoy.

“I’ll just tell my teachers I wasn’t feeling well,” I said. “Leaving campus now.”

“Wonderful,” Mom said.

I whistled as I headed for the door, my dick so hard to head to the sex shop and get the supplies I needed to dominate my little sister. I couldn’t wait for the brat to squeal on my big dick and cry out in ecstasy like the whore she was.

I loved our family tradition.

Derrick only has his little sister in his mind. He has no attraction to a dweeby, mousy, Plain Jane bookworm like me. He rushes out and quickly arrives. The owner knows his parents so Derrick knows he’ll get a great deal.

It’s not long before he’s heading home to dominate. She’ll be in for a surprise. He’ll make the little brat squeal with all the fun things he bought. Not once does Kristen enter his mind. He’s focused on what matters.

His hot little sister.

All I could think about was my hot little sister as I walked home. I had the BDSM supplies in a large shopping bag. I hoped I bought the right size corset. Mom texted me the size that should work. I would just have to trust her.

I walked up to the front door and opened it to the sight of my mom kneeling on the floor, her hands cuffed behind her. I shuddered at the sight of her big breasts thrusting out before her, both her nipples properly pierced. She had a ring gag in her mouth, forcing her jaw open. Her shaved pussy dripped with juices. She acted prim and proper because she was a true submissive wife.

She lived that Stepford life.

Dad held the leash attached to Mom’s collar. He wore a pair of leather pants and nothing else. He was strong and in great shape for an accountant. He didn’t have his glasses on. He grinned at me. This was it. I felt his pride.

“She’s in her room,” he said and tugged on the leash. Mom crawled after him as he headed toward the locked basement door. “Tell her it’s time. Take her downstairs. If she’s like your mother, you’ll have to drag her. She’ll want to know you’re man enough to ignore her tears and protest.”

“Right,” I said. “I won’t let you down, Dad.”

He clapped a hand on my shoulder as he walked past me. “I know you won’t, son. Your mother and I believe in you.”

Mom moaned and nodded as she shuffled by on her knees, her big boobs jiggling. She looked so sexy with her hands cuffed behind her back. She looked just perfect moving like that. I groaned at how plump her ass looked. She had such a dimpled rump.

She was a sexy slut. I loved it.

My dick was so hard as I headed down to my sister’s room. I knocked on her door.

“Go away,” she shouted, the music turning up.

I twisted the doorknob. It was locked.

“Amanda,” I said, knocking again louder. “Open this door right now. It’s time for you to be a slut. Amanda. Open the door.”

I knocked again as the music grew louder. I drew in a deep breath. What did Dad say… Right, right, a Master never lost control. He didn’t grow angry with a brat. He stayed in charge and put her in her place. That was what I had to do here.

I knew how to open the door. Sure, they were locked, but there was a little hole that you could slip a small tool in. The tool rested on the top of each door frame. I doubted my sister even knew about this little brass rod with a triangular handle.

I snagged it, pressed it into the lock, and pushed. The lock clicked. With how loud the Taylor Swift song she played was, I doubted she heard it. I smiled as I replaced the key and decided to get naked. She had to see me in charge. I set down the bag and ripped off my shirt. I shoved off my jeans and underwear. My dick popped out hard. I peeled off my socks and tossed them all into my room.

Mom would be mad if I made a mess. She was Dad’s sex slave, but that didn’t stop her from being my mother and wanting the house to be clean. She would even give Dad a stern look if he forgot to use a coaster. Oh, he might spank her ass hard for it later, but she didn’t tolerate her perfect house being disrupted.

That done, I threw open the door to my sister’s room.

She jumped on her bed and screeched, “GET OUT OF HERE!”

Amanda threw her pillow at me. I knocked it aside, her brown hair swaying. Mom was a blonde. Dad had dark hair. My sister and I were in between them. She reached for another pillow and hurtled it, her face red.

“I’m not yours!” she screeched. “GET OUT OF HERE!”

She grabbed a book and threw it at me. The corner hit me in the stomach. I grunted and reached her bed. She glared at me with defiance, daring me to use her. She opened her mouth to screech at me again.

I lightly slapped her face. Not hard. Just a tap to let her know she was being a brat. “Stop that. Good girls don’t shout. They speak at a normal volume.”

She sucked in a deep breath.

I slapped her again.

She blinked at that, her cheek growing a touch pink. Her brow furrowed as I pointed to the doors and snapped my finger. She crossed her arms in defiance and shook her head, her blue eyes glaring at me. The pose stretched her t-shirt taut over her small breasts, her nipples hard.

She wasn’t wearing a bra.
