Becoming Daddy’s Good Girl 9: Bratty Sister Transformed by mypenname3000

“Sluts,” Daddy growled. “Enough. None of you have permission to cum. Downstairs, now. It’s time to play.”

“Yes, Sir,” moaned Mommy, her eyes glossy with lust.

“Play?” mouthed Alice.

“In the dungeon,” I grinned.

“Dungeon?”

“The secret room in the basement we’re not allowed in.” I beamed. “I’ve been in there, and it is naughty.”

Daddy had played with Sun and me in that room when she slept over. I lost my anal cherry in there. Oh, that was so hot.

“Come along, sluts,” Mommy purred, “your father and I have waited eighteen years to play with you both.”

Alice’s eyes widened and I winked at her. I would explain later, but Mommy was raised to be her daddy’s sex slave, and then she met our daddy, fell in love, and grandpa sold her as part of the wedding ceremony. When she gave birth to twin girls, she was eager for our daddy to have the same experience.

She was such a wicked Mommy.

The three of us trailed after Daddy. He held Mommy’s braid like a leash, pulling her along while Alice and I walked behind her holding hands. My sister beamed. The stairs were two narrow for us to walk side-by-side. I let her go first.

I wanted to stare at her red ass. Ooh, Daddy spanked her hard.

Alice gasped when we entered the dungeon. The walls were black cork—to muffle sound, though that wasn’t needed any longer since we all were Daddy’s slaves now—and there was a spanking bench, a St. Anthony’s cross, hooks in the ceiling for suspension play, shelfs full of sex toys and BDSM delights, an assortment of paddles, whips, and canes on the walls, a chest full of rope.

“Wow,” Alice said, turning around in the room, her toes digging into the soft, black carpet. “I can’t believe this is in our house.”

I pulled her down so we knelt before Daddy, both of us staring up at him, trembling. He was so handsome, especially with the barbwire tattoos crossing his muscular torso and fire sleeve-tattoos. He stared at us, eyes intense.

“Believe it, dear,” Mommy said, kneeling beside Daddy. “Sir, how do you want your daughters prepared?”

“Nipples and clits clamped,” Daddy ordered. “And butt plugs.”

“Yes, sir,” Mommy said. She rose swiftly and moved to the cabinets.

Alice swallowed but didn’t look away.

Mommy returned swiftly, knowing just where to go, her hands full of supplies. She knelt beside Daddy. “Sir, do you want to apply them or shall I?”

“I think their mother should do it,” Daddy said, his dick thrusting hard before him.

“Yes, Sir,” purred Mommy. I saw the twinkle in her eye—Daddy rewarded her for birthing him two submissive daughters.

She crawled forward, kneeling before us. “Melody first,” she said, “since she’s such a good slut for Daddy.”

“Thank you, Mommy,” I smiled.

Mommy winked at me. I knew why I went first. I had to be an example for Alice. I kept my back straight, my round breasts thrust before me. My nipples were so hard. But that didn’t stop Mommy from leaning over and sucking on my right nipple. I gasped, the pleasure shooting right down to my pussy. I squirmed, my hands behind my back aching to clasp together.

Then Mommy’s lips popped off my nipple and she replaced it with the clamp in a heartbeat. I sucked in a breath at the sharp pain flaring in my nipple. The alligator clamp bit into my nipple. The weight pulled it down. In moments, my nipple throbbed with a painful ache.

Daddy’s eyes smiled as he watched, pleased.

“Wow, Melody,” Alice said, staring at my clamped nipple in awe. “Does that hurt?”

“Uh-huh,” I said, my voice strained by the pain. “But that’s what makes it wonderful.”

“You’re not the only pain-slut in the family, Alice,” Mommy purred before she sucked on my other nipple.

I groaned. The duel sensations of pleasurable nursing and painful clamping shuddered though me. The conflicting inputs from my two nipples made me squirm and moan. I groaned as Mommy sucked so hard on my nipple. It made the other one throb even harder, the pleasure reminding me of the pain.

Then Mommy’s lip popped off and the clamp snapped on. I groaned, shuddering. The pain was exquisite. Agony throbbed along both my nipples while Mommy kissed down my stomach. I rose up on my knees, giving her access to my pussy.

“Mommy,” I moaned as her fingers parted my silt and her lips sucked on my clit. “Oh, Mommy, yes.”

Alice’s eyes were wide with awe as she stared at both my clamped nipples. As my breasts jiggled, the nipple clamps waved, stretching and pulling on my nipples. Pleasure rippled through my body, crashing into the agony. I grit my teeth, the two sensations so wonderful. Her lips so soft, the clamps so hard.

And then true agony shot through me.

I screamed and threw back my head as she clamped my clit. My pussy convulsed. I came so close to cumming as my poor, aching clitoris throbbed in the padded grip of the smaller clamp. Even with the felt padding on the clamp, it hurt so badly.

So wonderfully.

“That’s my good girl,” Daddy growled, watching us submit to him.

“T-thank you, Daddy,” I answered, squirming. Every movement made the clit clamp pull on my nub.

“Mmm, you are such a good girl for Daddy,” Mommy moaned. “You make me so proud.”

“Thank you, Mommy,” I said, tears beading in the corners of my eyes.

I hardly felt her insert the lubed butt-plug. It wasn’t the largest I had taken. I groaned, shuddering and twisting as it settled into my bowels. The intrusion paled compared to the agony throbbing my clit and nipples.

I took deep breaths, controlling the pain and the excitement it generated. I fought against my wet pussy’s desire to be frigged as Mommy moved onto Alice. I looked at my sister, and gave her a tight, encouraging smile. She nodded back, resolved to submit.

“Alice,” Daddy said. “If at any point this is too much for you, say red light and it stops. I’m not here to harm you, only hurt you.” He smiled. “Give you the pain you crave. Don’t be afraid to say it.”

That was the safe word. Well, Mommy and I didn’t need the safe word. We were Daddy’s true slaves, but Alice hadn’t gotten there, yet. She would.

“I won’t, Daddy,” Alice said. “I’ll be your good girl.”

“I know you will.” His smile faded, growing stern, the dominating Master again. “June, clamp our daughter-slut.”

“Yes, Sir.”

Mommy leaned down and sucked on Alice’s nipple. Mine throbbed again, in remembrance of the pleasure my sore nubs had forgotten. Alice’s face twisted. Her eyes fluttered. A low moan escaped her lips that choked off into a gasp as Mommy clamped her small nipple. She used the padded clamps, not the alligator teeth.

But Alice still winced and grit her teeth. She squirmed as Mommy kissed over to her other nipple. I stared at the pink nipple clamped, loving how the teeth squeezed it and how she squirmed, experiencing the duel delights.

“You love it, don’t you, slut?” I smiled.

“I do. I really…doooo!” Mommy clamped her other nipple, transforming her words into a pain-filled moan. “Oh, thank you, Daddy, for showing me this.”

“You’re welcome, slave.”

“And you’re…going to take my cherry, Daddy?” she asked while Mommy kissed and nuzzled her way down to my sister’s cunt.

“What do you think, whore?” answered Daddy, staring at Alice.
