Chapter 9: **My Baby Sis Is Bad**

She held her hands in the air eyes locked on Nini.

“I understand, Gaffney,” she said, her gaze dropping to my sister’s full breasts. “Because your sister is so fucking hot.”

My breath hitched.

“Yes, girl,” Nini purred excitedly, arching her back. “Come join us.”

My eyes stayed fixed on Jess while my stupid cock kept pounding deep into Nini’s tight, slippery pussy.

“I want you, Nini,” Jess breathed.

I furrowed my brow.

“I’m tired of your prick, Gaffney. I want your sister’s body.” Her voice dropped. “And nobody will ever hear about what just happened here.”

“I’m not a lesbian, Jess… I can’t —”

Jess reached out and squeezed Nini’s breast. My sister moaned loudly, hips rolling against me. “Fuck, Jessica… ride me.”

Jess stripped with hungry urgency, clothes hitting the floor. She climbed onto the bed and dropped onto all fours over Nini, ass raised, pussy already glistening.

“Give it to me from behind,” she said, looking back at my cock, thick and shiny with my sister’s juices. “Don’t waste that cum. Shove it in me while it’s still dripping from her.”

I pulled out of Nini with a wet sound. My sister whimpered at the sudden emptiness. Jess reached back, spread herself open, and I slammed into her in one hard thrust. She was tight, hot, and greedy, clenching around me like she was trying to milk me dry.

Nini watched, eyes glassy, lips parted. Jess didn’t waste a second. She leaned down and sucked one of my sister’s nipples into her mouth, biting just enough to make Nini gasp.

“Fuck… Jess…” Nini moaned, hands sliding into Jess’s hair. “That feels so dirty.”

“You like it,” Jess mumbled around the soft flesh, then switched to the other breast. “Your brother’s cock is still stretching me and I’m already tasting you, You're so sweet”

I gripped Jess’s hips and started pounding her hard, the wet slap of skin filling the room. Every thrust shoved her deeper against Nini. My sister’s legs were still spread, her pussy puffy and slick from me, and Jess’s hand drifted down between them.

Two fingers pushed into Nini. My sister’s back arched off the bed.

“Oh god… yes —”

“Listen to her,” Jess panted, looking back at me over her shoulder while I fucked her. “Get your cock busy and fuck me harder.”

Nini’s eyes locked on mine. There was no shame left in them — only heat and something darker.

“Harder,” she whispered. “Fuck her harder, Gaffney. I want to feel it through her.”

I obeyed. My hips snapped forward, burying myself to the hilt again and again. Jess moaned around Nini’s nipple, fingers working faster inside my sister. The wet sounds mixed — my cock sliding in and out of Jess, Jess’s fingers pumping into Nini.

“You’re both so fucked up,” Jess gasped, pulling off the nipple with a wet pop. “Brother and sister sharing a bed like this… and I’m right in the middle of it. Now this feels like sex.” She turned her head and kissed Nini full on the mouth, deep and filthy. Tongues sliding, saliva mixing.

Nini kissed her back without hesitation.

I felt my orgasm building, heavy and inevitable. Jess must have felt it too — she clenched around me deliberately.

“Don’t you dare pull out,” she ordered. 

Nini reached up and grabbed my wrist, eyes locked on mine while Jess’s tongue was still in her mouth.

“Do it,” my sister whispered against Jess’s lips. “Fill her up. Then I want to taste it.”

That broke me. I slammed deep and came hard, pulsing thick ropes into Jess while she kept fingering my sister. Jess moaned into the kiss, grinding back against me, milking every drop. When I finally slowed, she pulled off my cock with a filthy wet sound. Cum immediately started leaking out of her and dripping onto Nini’s stomach.

Jess didn’t hesitate. She crawled lower, spread Nini’s thighs wider, and licked a long stripe up my sister’s cunt, gathering the mess that had dripped down. Then she pushed her tongue inside Nini and fucked her with it while two fingers stayed buried deep.

Nini’s hands flew to Jess’s hair, hips rolling up.

“Fuck… Jess… don’t stop.”

I sat back on my heels, still half-hard, watching my sister get eaten out by the girl who’d just taken my load. Jess’s face was buried between Nini’s legs, making filthy wet noises, clearly enjoying every second of the taboo she’d walked into.

Nini’s eyes found mine again over Jess’s head. Her voice came out rough, almost breathless.

“Come here,” she said. “I want your cock in my mouth while she finishes me.”

I moved up the bed. Nini opened her mouth and took me in, tasting herself mixed with Jess on my skin. She sucked slowly, eyes never leaving mine, while Jess kept working her tongue and fingers between her thighs.

The three of us were tangled, sweaty, and completely past the point of pretending this was anything but wrong.

“Nini…” Jesz finally spoke. “I've taught you enough, time to give me pleasure. And like that, we switched places.
