The house was quiet except for the low hum of the air conditioner and the occasional creak of floorboards as the night settled in. Mom had just turned forty-eight but still looked like she could make any man drop to his knees. Dad was out of town on business again, leaving the rest of us to our own devices. My sister Lisa, twenty-five and built like a wet dream with heavy tits and an ass that begged to be grabbed, was sprawled on the couch in nothing but a thin tank top and panties. Our cousin Jake, twenty-six and already hard just from looking at her, sat in the armchair pretending to scroll his phone.
I was twenty-four and done pretending. "Fuck this," I said, standing up and yanking my shorts down. My cock sprang free, thick and already leaking. "We've all been thinking it for years. Dad's gone. Let's stop dancing around it."
Lisa looked up, eyes locking on my dick. A slow smile spread across her face. "About fucking time you said it out loud, little brother." She hooked her thumbs in her panties and slid them off, spreading her legs so we could see her shaved pussy already glistening.
"Come eat this cunt if you're serious."
Jake didn't need more invitation. He crossed the room in two strides, dropped to his knees, and buried his face between her thighs. The wet sounds of his tongue lapping at her folds filled the room immediately. Lisa moaned, grabbing his hair. "Yeah, cousin, suck that clit. Make it sloppy."
I moved behind her on the couch, pulling her tank top up so her big tits spilled out. I squeezed them hard, pinching her nipples while I rubbed my cock against the back of her neck. "You always were the family slut, Lisa. Now you're our family slut."
She laughed breathlessly, pushing Jake's head deeper. "Damn right. Both of you fuck me tonight. Fill every hole."
Jake stood, cock out and throbbing. He flipped her onto her hands and knees on the couch cushions. Without warning he slammed into her pussy from behind, making her yelp and then groan. "Fuck yes, stretch me open." I climbed onto the couch in front of her, feeding my cock into her mouth. She sucked greedily, drool running down her chin as Jake pounded her.
The three of us moved like we'd been practicing this for years. Jake gripped her hips, driving deep with wet slaps. I fucked her throat, holding her head steady. Lisa moaned around my shaft, pushing back to meet every thrust. "Harder," she gasped when I pulled out for air. "Use me like the dirty incest whore I am."
We switched. I took her pussy next while Jake fed her his cock. Her walls gripped me tight and hot, slick with her juice and his spit. I slapped her ass red, watching it jiggle. "This is what family sex fun looks like," I growled. "Mom's probably upstairs listening and fingering herself."
As if on cue, Mom appeared in the doorway wearing only a silk robe that fell open. Her tits were full and her nipples stiff. "I was wondering when you kids would finally stop hiding it," she said, voice husky. She let the robe drop and walked over, climbing onto the couch. "Room for one more?"
Lisa pulled off Jake's cock long enough to grin. "Get that pussy on my face, Mom."
Mom straddled Lisa's head, lowering her wet cunt onto her daughter's tongue. The sounds got filthier—Lisa licking and sucking while I kept railing her from behind and Jake fucked her mouth again. Mom rode Lisa's face, moaning and pinching her own nipples. "That's it, baby girl. Eat Mommy's cunt while your brother and cousin wreck you."
We kept rotating positions for what felt like hours. I fucked Mom bent over the arm of the couch while Jake took Lisa on the floor. Then Lisa and Mom kissed deep, swapping spit and tasting each other's pussies while Jake and I took turns sliding into them. Cum started flowing early—Jake unloaded first, painting Lisa's tits and face. I followed, pumping a thick load into Mom's pussy, watching it drip out when I pulled free.
None of us stopped. Lisa climbed onto my lap facing me, sinking down on my still-hard cock while Mom sucked Jake back to life. "More," Lisa demanded, bouncing hard. "I want both of you in me at once."
We made it happen. Jake took her ass while I stayed in her pussy, the two of us stretching her between us on the couch. She screamed through it, coming so hard she shook. Mom watched, fingering herself and talking dirty. "Look at my daughter taking two family cocks. That's my good girl."
By the time we finished, the living room smelled like sex and sweat. Bodies tangled on the furniture, cum leaking from every hole, everyone breathing hard and smiling. Lisa licked a streak of Jake's load off Mom's thigh. "Same time tomorrow?" she asked.
Mom laughed low. "Every night Dad's away. This is our house now."
We cleaned up just enough to stumble to our rooms, already planning the next round. Family sex fun had officially begun, and none of us wanted it to end.
