Darkest Cravings (90 Types Of Lust)

Chapter 8: Baby Sis Is Bad

**New collection**

She spread my legs wide and climbed between them like she belonged there.

I turned my face away, jaw locked so tight it hurt.

“Gaffney… look how wet I am for you. Please.”

“I’m holding myself back, Nini. Don’t make it worse. Don’t f*****g make it worse.”

“Make it worse,” she breathed, and stripped.

Clothes hit the floor. Her heavy breasts swayed free, n*****s already tight. My eyes betrayed me — locked on them, then lower, to the slick shine between her thighs.

I’d been fighting this since the night she turned nineteen and walked in on me f*****g my girlfriend. She’d stood there staring, lips parted, hand between her legs like she couldn’t help it. After that she stopped pretending. Started leaving the door open when she showered. She started crawling into my bed at 3 a.m, “just to sleep.” Started whispering ‘brother’ against my neck while she rubbed herself on my thigh.

Now she was naked, kneeling over me, pulling my c**k free with zero hesitation.

“You’re leaking,” she whispered, almost reverent. “For your baby sister.”

“Nini…stop.”

She didn’t. She straddled me, guided the swollen head through her folds, and sank down in one slow, deliberate slide until I was buried to the root inside my own sister’s cunt.

The sound that left me was ugly. Broken.

She was so f*****g tight. Hot, and wet. Pulsing around me like she’d been made for this exact sin.

“Feel that?” she moaned, rolling her hips. “Does it still feel wrong when I’m this wet for you?”

I grabbed her hips hard enough to bruise and slammed up into her.

“Yes,” I snarled against her mouth. “It feels f*****g wrong. You’re my blood. I raised you. I shouldn’t be balls-deep in you right now…”

She kissed me filthy, tongue and teeth, riding me harder.

“But you are. And you’re going to come inside me. You’re going to fill your baby sister up until it leaks down my thighs. Then you’re going to do it again. And again. Because this is mine now.”

My c**k was a betrayal. I flipped her onto her back, pinned her wrists above her head, and drove into her like I was trying to punish us both. The bedframe slammed the wall. Her t**s bounced with every thrust.

“Brother …. Gaffney” She kept moaning

“Tell me you hate it,” she gasped, legs locked around my waist. “Tell me you hate how good your sister’s cunt feels.”

I couldn’t.

I buried my face in her neck, breathed in the scent of her skin, and f****d her deeper, harder, like the only way out of this was through her.

When I came it was with a broken groan against her throat, flooding her while she clenched and shook and whispered. “Good boy… give it all to me. Breed your baby sister.”

I stayed buried in her, c**k still twitching as the last pulses left me. Her cunt fluttered around me, milking every drop like it was starving for it. Sweat stuck our skin together. Her thighs trembled against my hips.

Nini’s fingers stroked through my hair, almost gentle.

I should have pulled out. Should have shoved her off, told her this was the last time, that we were both f****d in the head. Instead I stayed locked inside her, breathing hard against her throat, feeling my own c*m start to leak around the base of my c**k.

Then the front door opened downstairs.

Keys dropped and Footsteps echoed in the hall.

And a A familiar voice called up the stairs.

“Babe? I was bored at home, so I came earlier. You upstairs?”

My blood went ice-cold. It was Jessica…. My girlfriend.

I tried to move. Nini’s legs locked tighter around my waist. Her eyes were calm. Almost soft.

“Don’t,” she whispered against my mouth. “Stay inside me.”

I swallowed hard as even my c**k didn't want to let go.

Heavy steps on the stairs. The bedroom door wasn’t even closed…

Jessica pushed it open mid-sentence. “I brought ice cream, figured we could..”

Her voice trailed. She Took in the scene in one long, silent second: me still balls-deep in my naked sister, c*m leaking out of her around my c**k, Nini’s wrists still pinned above her head from when I’d held her down.

Jessica’s face didn’t collapse the way I expected.

My eyes traveled with her as she set the takeout bag on the dresser without looking away. Her voice came out quiet and controlled.

“So this is why you’ve been distant.”

Nini turned her head, cheek pressed to the pillow, and smiled at her without panicked, nor same.

“He came inside me,” she said, soft and almost proud. “He’s been fighting it for months. And I've satisfied him.”

I finally found my voice. “Jess…this isn’t..I didn’t mean —”

Jessica stepped closer to the bed. Her eyes dropped to where my c**k was still buried in Nini, the mess already smearing her sister’s thighs. Then she looked at me.

“How long?”

Nini answered for me. “Since the night I walked in on you two. I never stopped wanting it after that.”

Jessica’s throat moved as she swallowed. She reached out and touched Nini’s ankle, tracing upward. Not pushing her away.

Her gaze settled on me. “You're cheating on me with your sis?”

“Jess…”

She held her hands in the air…
