She was nineteen when she moved back in. I walked through the door after my shift and there she was on the couch, legs spread in those tiny shorts, no bra under her tank top. "Hey Daddy," she said, and the way she said it made my cock twitch right away.
I tried to play it cool at first. Told her she could stay as long as she needed. But the house felt different with her there. Every time she bent over to grab something from the fridge, I stared at that round ass. She knew. She started wearing less. One night she came out of the shower wrapped in a towel that barely covered her tits and asked if I wanted to watch a movie.
We sat on the couch. She scooted close. Her bare thigh pressed against mine. Halfway through the movie her hand landed on my leg, then slid higher until her fingers brushed the bulge in my jeans. "You're hard, Daddy," she whispered. No teasing, just straight talk.
I didn't stop her.

She unzipped me, pulled my cock out, and started stroking it slow and firm. "I always wanted to do this," she said. Then she leaned down and took me in her mouth. Hot, wet, sucking hard like she had been practicing. I grabbed her hair and fucked her throat while the movie played. She gagged but kept going, drooling down my shaft.
When I was close I pulled her up and bent her over the arm of the couch. Yanked those shorts down. Her pussy was shaved and dripping. I shoved two fingers in first, then lined up and slammed my cock balls-deep in one thrust. She moaned loud. "Fuck me, Daddy. Use that tight cunt." I did. Hard and fast, slapping her ass, calling her my dirty little girl while I pounded her. She came twice before I flooded her pussy with cum.
After that it became every day. Mornings she'd crawl into my bed naked and ride me, tits bouncing, telling me how much better my cock felt than any boy's. Afternoons she'd drop to her knees in the kitchen and swallow my load before I went to work. Nights we fucked in every room. She'd beg for it rough: "Spank me, Daddy. Choke me while you fuck your daughter." I did. I held her down and railed her ass one night after she asked for it. She screamed and came so hard she shook.
We didn't hide it from each other. She told me exactly what she wanted: "Cum in my mouth, Daddy. Let me taste it." Or "Fill my pussy again. I want to feel it leak out all day." I told her she was my slut now, my personal fuck toy. She loved it.
One weekend we didn't leave the house. She stayed naked the whole time. I fucked her on the kitchen table, bent over the washing machine, against the shower wall. She sucked me off while I watched the game, then climbed on and bounced on my dick until I came inside her again. By Sunday night we were both sore but she still climbed on top for one more round, grinding slow and dirty, whispering "I love being Daddy's cumdump."
We kept it going. No guilt, no talking about stopping. Just raw fucking whenever we wanted. She was legal, she was willing, and she was mine.
