She was already on her hands and knees on the living room rug when I walked in, her shorts yanked down to her knees and her bare ass pushed up high. "Daddy, come on," my oldest daughter hissed, looking back over her shoulder. "You said you'd fuck me like this today. Don't make me wait."
I didn't waste time talking. I dropped my jeans, stepped behind her, and shoved my cock straight into her wet cunt in one hard thrust. She grunted and pushed back, taking every inch. Her sister was on the couch watching, legs spread, two fingers already working her own pussy while she waited her turn.
"Fuck, your ass looks good like this," I growled, gripping her hips and slamming into her. The sound was loud and wet every time my balls slapped her. She moaned and dropped her chest lower so her ass stayed up, exactly the way I liked it. Doggy style always made her feel tighter, and she knew it.
I reached under her and grabbed her tits, squeezing hard while I pounded her. "Tell me whose cunt this is."
"Yours, Daddy. Always yours." Her voice was already shaking. I fucked her faster, the slap of skin on skin filling the room. Her sister on the couch whimpered and rubbed her clit quicker, eyes locked on where my cock disappeared into her sister's hole.
When I pulled out she whined, but only until I shoved back in even deeper. I spit on her asshole and rubbed it with my thumb while I kept driving into her pussy. "You want it in your ass next?" I asked.
"Yes," she panted. "After you cum in me first. Fill me up."
I gave her exactly what she asked for. I hammered her until my balls tightened and I unloaded deep inside her, thick ropes of cum pumping into her cunt while she pushed back and took it all. She stayed on her knees, shaking, cum already starting to leak out around my cock.
Her sister didn't wait. She crawled off the couch, got on all fours right beside her, and wiggled her ass. "My turn, Daddy. Put it in me the same way."
I pulled out of the first one, my cock still hard and shiny with cum and her juices, and moved behind the second daughter. She reached back and spread her cheeks for me. "Shove it in," she said. "I want to feel how sloppy you made her."
I sank into her in one stroke. She was even tighter. I grabbed a fistful of her hair and yanked her head back while I fucked her hard and fast. The wet sounds were filthier now with my cum mixing in. Her sister watched from the side, still on her knees, fingering the load I'd left in her.
"Harder," the one I was inside begged. "Use me like a fucktoy."
I did. I drove into her with everything I had, hips snapping, her ass rippling every time I bottomed out. When she started to cum I reached around and rubbed her clit rough and fast until she screamed and clamped down on my cock. I kept fucking her straight through it, chasing my own second load.
By the time I filled her too, both daughters were dripping.

I pulled out and watched my cum run down their thighs while they stayed on all fours, asses up, waiting to see what I'd do next.
"Clean each other up," I told them. "Then get back in position. I'm not done with either of you yet."
They turned to each other without hesitation, tongues out, licking my cum off each other's thighs and cunts while I stroked myself hard again. The night was just getting started.
