I never planned to fuck my son's girlfriend. But the second she bent over to grab a beer from the fridge, that tiny skirt riding up her ass, I knew I was going to pound her raw.
Her name was Mia. Twenty-one, tight little body, perky tits that bounced when she laughed. My son brought her home for the weekend, and the first night they were both passed out drunk in the guest room. I stayed up, cock already half-hard just from the way she'd looked at me earlier. She knew what she was doing, flashing those eyes and crossing her legs so I caught a glimpse of her thong.
I went downstairs for water and found her in the kitchen, alone. She was wearing nothing but an oversized t-shirt that barely covered her ass.
"You can't sleep either?" she asked, voice low.
I didn't answer with words. I grabbed her by the hips, spun her around, and shoved her against the counter. My hand went straight between her legs. She was already wet, pussy lips slick and hot.
"Fuck," I muttered. "You're dripping."
She pushed back against my hand. "Your son's asleep upstairs. We shouldn't."
I yanked her thong aside and shoved two fingers into her tight cunt. She was soaked, clenching around me. "You want this dick or not?"
Mia moaned and spread her legs wider. That was all the answer I needed. I freed my cock, thick and throbbing, and slammed it straight into her from behind. No teasing, no slow shit. Just raw, hard fucking. Her pussy gripped me like a vice, hot and slippery. I pounded her deep, balls slapping against her clit with every thrust.
She bit her arm to stay quiet, but little whimpers still slipped out. "Harder," she hissed.

"Fuck me harder, daddy."
I grabbed a fistful of her hair and railed her like I owned her. The wet sounds of my cock slamming into her pussy filled the kitchen. Every stroke bottomed out, stretching her open. She came fast, pussy pulsing and squirting a little around my shaft. I didn't stop. I kept driving into her until my balls tightened and I unloaded deep inside her, flooding her cunt with thick ropes of cum.
We cleaned up quick and went back to our rooms. But that was only the start.
The next morning, while my son was in the shower, she cornered me in the hallway. She dropped to her knees, pulled my cock out, and sucked it like a slut who needed it. Her tongue worked the head, then she took me to the back of her throat, gagging quietly while spit ran down her chin. I fucked her face until I was ready to blow, then pulled out and painted her tongue with another load.
By the third night, we weren't even hiding it well. My son went to bed early. Mia waited ten minutes, then slipped into my room. She stripped naked and climbed on top of me, sinking that tight pussy down on my cock in one smooth motion.
"Ride it," I told her. "Show me how bad you want it."
She bounced on my dick, tits jiggling, ass slapping against my thighs. I reached up and pinched her nipples hard while she ground her clit against me. Every time she dropped down, she took me balls-deep. Her juices coated my shaft and balls. I flipped her onto her back, hooked her legs over my shoulders, and fucked her stupid. Deep, punishing strokes that made her eyes roll back. She came twice, soaking the sheets, before I pulled out and shot my load across her stomach and tits.
We kept going until the sun came up. She let me use every hole. I bent her over the bed and took her ass, working my cock into that tight ring while she fingered her pussy. She begged for it harder, dirtier, until I filled her ass too.
By the time my son woke up, Mia was back in the guest room, my cum still leaking out of her. She smiled at me over breakfast like nothing happened. But we both knew it wasn't over.
Every time she visits now, she finds a way to get alone with me. Quickies in the laundry room, bent over the washing machine while my son watches TV. Blowjobs in the garage with the door half-open. Sometimes I text her to meet me at a hotel when my son is at work. She shows up, drops her clothes, and lets me wreck her for hours. I fuck her in every position, make her scream my name, and leave her pussy and ass sore and full of cum.
She always comes back for more. And I always give it to her raw, dirty, and exactly how she needs it.
