The house was quiet when I got home from work, but I knew they were waiting. Mom had texted earlier, just a simple "he's home soon" with a winking emoji that made my cock twitch in my jeans. My dick was already half-hard, thick and heavy, the kind of meat that stretched every hole it touched. At twenty-two, I was the man of the house now, and they both craved it.
I walked into the living room and found them on the couch. Mom, forty-five and still thick in all the right places, her big tits barely contained in a low-cut top. My sister Lisa, nineteen and slim but with an ass that jiggled when she walked, sat beside her in nothing but a tiny tank and panties. Both of them looked up with hungry eyes.
"Strip," I said, voice low and rough. "Show me those wet cunts."
They obeyed fast. Mom pulled her top off first, heavy tits spilling out, nipples dark and stiff. Lisa wiggled out of her panties, already glistening between her legs. I dropped my pants and my cock sprang free, long, veined, and thicker than either of them could wrap a hand around. It bobbed heavy, the head shiny with precum.
"Fuck, look at that big cock," Mom breathed, crawling forward on her knees. She grabbed the base with both hands and still had room to spare. Her tongue dragged up the underside, slow and wet, before she opened wide and sucked the head in. I groaned as she bobbed, taking more each time, gagging when it hit the back of her throat.
Lisa watched, rubbing her clit. "Mom, share. I need it too."
Mom pulled off with a wet pop and shoved my cock toward my sister. Lisa licked the spit-slick head, then tried to swallow as much as she could. Her lips stretched tight around the girth. I grabbed her hair and pushed deeper, fucking her mouth in short thrusts until tears ran down her cheeks.
"Both of you on the couch," I ordered. "Asses up."
They lined up side by side, knees on the cushions, faces down. Two perfect asses presented for me. I stepped behind Mom first, rubbing my fat cockhead through her soaked folds. She was dripping, ready.

I pushed in slow, watching her pussy lips stretch around me. Inch after thick inch sank into her until my balls pressed against her clit.
"Oh god, baby, you're splitting me open," she moaned, pushing back. I gripped her hips and started pounding, the wet slap of skin loud in the room. Her cunt clenched tight, milking every vein on my shaft. Lisa reached over and rubbed Mom's clit while I fucked her.
When Mom came, she screamed into the cushion, pussy pulsing around my cock. I pulled out, my dick shiny with her cream, and moved behind Lisa. She was tighter, younger, and she whimpered as I forced my way in.
"Too big," she gasped, but she rocked back anyway, taking more. I bottomed out and held there, letting her adjust before I started thrusting hard. Her ass rippled with every slam. Mom watched, fingering herself, telling us how hot it looked.
I switched between them for what felt like hours, pounding one then the other, making them taste each other's pussy on my cock. When I was close, I pulled them both to their knees in front of me. They pressed their faces together, tongues out, while I stroked my massive shaft.
"Open wide," I growled. Thick ropes of cum splattered across their tongues, their tits, their faces. They licked it up, sharing sloppy kisses, swallowing what they could.
Later, after we cleaned up, they curled against me on the couch, still naked. Mom stroked my softening cock lazily. "Same time tomorrow?" she asked.
Lisa kissed my chest. "I want it in my ass next."
I smiled, already feeling the blood rush back. This was our family now, raw and filthy and exactly what we all needed.
