I was in the kitchen nursing a beer when my daughter walked in with her friend. Both of them were eighteen, fresh out of high school, and they knew exactly what they were doing. My daughter, Emily, had that same smirk she got when she wanted something. Her friend, Kayla, was shorter, curvier, with big tits barely held by a tiny tank top.
"Daddy, we're home," Emily said, dropping her bag. She came straight over and hugged me from behind, pressing her perky tits against my back. "Missed you."
Kayla leaned on the counter, watching. "Your dad is hot, Em. Bet he gets lonely when you're gone."
I tried to play it cool, but my cock twitched. "You girls behave."
Emily laughed and slid her hand down my chest. "We don't want to behave tonight." She looked at Kayla. "Told you he'd be easy."
Kayla walked over and pressed against my side. Her hand went straight to my crotch, squeezing my growing hard-on through my jeans. "Fuck, he's already hard. Daddy likes us."
Emily didn't hesitate. She turned me around and kissed me hard, tongue pushing into my mouth. Kayla joined in, her lips on my neck while her fingers unzipped me. My cock sprang out and she wrapped her hand around it, stroking slow and tight.
"Jesus, girls," I groaned, but I didn't stop them. Emily dropped to her knees first, sucking the head of my dick into her warm mouth. Kayla joined her, licking the shaft, both of them looking up at me with dirty eyes.
Emily pulled off and stood, yanking her shorts down. "Fuck me first, Daddy. I've wanted this forever." She bent over the counter, ass up, pussy already wet and pink. I grabbed her hips and shoved my cock in deep. She moaned loud, pushing back against me.
Kayla stripped too, climbing onto the counter so Emily could eat her out while I fucked my daughter. The wet sounds filled the kitchen. Emily's tight cunt gripped me, her juices running down my balls. Kayla held Emily's head, grinding on her tongue. "That's it, make her cum while her daddy pounds her."
I slammed harder, watching my daughter's ass ripple. She came first, shaking and moaning into Kayla's pussy. I pulled out and switched, driving into Kayla next. She was tighter, screaming as I stretched her. Emily fingered herself while watching, then got on her knees again to suck me clean between switches.
We moved to the couch. I sat back and let them ride me in turns. Emily straddled me, bouncing on my cock while Kayla sat on my face, smothering me with her wet slit. I licked her clit until she squirted, then flipped Emily onto all fours and took her from behind again.
Kayla crawled underneath, licking my balls and Emily's clit at the same time. "Fill her up, Daddy.

Cum in your daughter's pussy." The dirty talk pushed me over. I buried deep in Emily and unloaded, thick ropes pumping into her. She came again, clenching around me.
We didn't stop there. They sucked me hard again and I fucked Kayla next, dumping another load in her while Emily kissed me and whispered how long she'd wanted this. By the end we were all sweaty, sticky, and satisfied on the living room floor. Emily curled against one side, Kayla on the other, both of them tracing fingers over my spent cock.
"Same time tomorrow, Daddy?" Emily asked, already stroking me back to life.
I just nodded, already thinking about round two.
