I had always known my aunt Lisa was off-limits, but that never stopped the way my cock twitched every time she bent over in those tight jeans. At twenty-three, I was home for the summer after college, and she was forty-two, divorced, and living alone in the big house on the edge of town. She invited me over for dinner one Friday, and by the time the plates were cleared, the air between us was thick with something filthy.
She poured us both another glass of wine and said it straight. "You've been staring at my ass all night, haven't you, Jake?"
I didn't deny it. "Yeah. It's perfect. I want to fuck it."
Lisa smiled, slow and dirty. "Then come upstairs and take what you want. But we're not telling anyone. This stays between us."
We barely made it to her bedroom. She stripped fast, peeling off her top and bra, letting those heavy tits bounce free. Then she turned around, hooked her thumbs in her panties, and shoved them down. Her ass was round, pale, and smooth, the kind of ass that begged to be spread and claimed. She climbed onto the bed on all fours, reached back, and pulled her cheeks apart.
"Look at that tight little hole," she said, voice low. "You want to shove your cock in there, don't you? Want to fuck your aunt's ass raw?"
I was already naked, my dick rock-hard and leaking. I stepped up behind her, spit on my fingers, and rubbed the slickness over her asshole. She pushed back against me. "Don't be gentle. I want it rough."
I lined up and pressed the head of my cock against her rim. She was tight, really tight, but she relaxed and let me push in. Inch by inch, my thick shaft sank into her hot, gripping ass. Lisa moaned loud and filthy. "Fuck, yes. Stretch your aunt's asshole. Fill it up."
Once I was balls-deep, I started thrusting. Hard, steady strokes that made her cheeks slap against my hips. Her hole clenched around me like a fist, hot and slick from the spit and the way her body was already opening for me. I grabbed her hips and pounded harder, watching my cock disappear into that forbidden ass over and over.
Lisa reached between her legs and rubbed her clit, fingers moving fast. "Deeper. Fuck me deeper. I want to feel you in my guts."
I gave her exactly what she asked for. I pulled almost all the way out, then slammed back in, burying every inch. Her moans turned into desperate grunts. Sweat ran down her back. The room smelled like sex and skin and pure lust.
I reached around and pinched her nipples, twisting them while I kept driving into her ass. "You like your nephew's cock in your ass, don't you? You dirty fucking aunt."
"Yes," she gasped. "I love it. Use me. Wreck my asshole."
I flipped her onto her back, pushed her legs up to her chest, and sank back into her. In this position I could see her face while I fucked her ass—eyes half-closed, mouth open, tits bouncing with every thrust. I spit on her pussy and rubbed it, then slid two fingers inside her cunt while my cock kept stretching her ass.
She came hard, clenching around my fingers and my dick at the same time. Her asshole pulsed and fluttered, milking me.
I didn't stop. I kept pounding through her orgasm, making her shake and curse.
When I was close, I pulled out, flipped her back onto all fours, and shoved back in for the final stretch. "Gonna fill your ass," I growled.
"Do it. Pump your cum deep in your aunt's ass."
I slammed in one last time and unloaded, thick ropes of cum flooding her tight hole. I stayed buried, grinding against her while the last pulses emptied out of me. When I finally pulled out, a trickle of my load leaked from her stretched rim.
Lisa reached back, scooped some of it onto her fingers, and licked them clean. "We're doing this again tomorrow," she said. "And the next day. My ass is yours now."
I was already getting hard again just watching her.
