I never expected my mom to be the one begging for it in the ass. At 42 she was still hot as hell, thick thighs, heavy tits that bounced when she walked, and a mouth that could talk filth like nobody's business. We'd been fucking for three months already, ever since she caught me jerking off to her old bikini photos and decided she wanted the real thing. Mom was kinky from the start. She loved riding my cock in the kitchen, sucking me off while dad was at work, and telling me exactly how deep she wanted it. But she'd never let me near her ass. That changed one rainy Thursday night.
We were in her bedroom, door locked, lights low. She was on all fours on the bed, ass up, face down in the pillows. Her pussy was already dripping from the pounding I'd just given her. I pulled out, my cock slick with her juices, and rubbed the head against her tight little hole. She froze.
"Not yet," she said, voice muffled. But her hips pushed back a little, like her body was arguing with her words.
I leaned over her, grabbed a fistful of her hair, and growled in her ear. "You've been teasing me about this ass for weeks, Mom. Time to give it up."
She moaned, low and dirty. "It's my first time there, baby. Be rough but go slow. I want to feel every inch stretching me open."
I grabbed the lube from the nightstand, poured a thick line down her crack, and worked two fingers into her. She was tight, hotter than her pussy, clenching hard around my knuckles.
I finger-fucked her ass while I told her what a filthy mom she was, how she was going to take her son's cock where no one else ever had. Her breathing got ragged. She reached back and spread her cheeks wider for me.
"More," she demanded. "Three fingers. Stretch your kinky mom's asshole."
I pushed in a third. She gasped and started rocking back on my hand. Her free hand slipped between her legs and she rubbed her clit in fast circles. When she was panting and pushing hard, I pulled my fingers out, lined my cock up, and pressed the head against her hole.
"Push out," I told her. "Let me in."
The head popped past her ring and she let out a long, shaking moan. I stayed still, letting her adjust to the thickness. Her asshole fluttered and squeezed, trying to push me out and pull me in at the same time. Inch by inch I sank deeper, watching her pink rim stretch tight around my shaft. She was swearing under her breath, calling herself a dirty anal slut, telling me how full she felt.
When my balls finally rested against her wet pussy, I held there and reached under to pinch her nipples. "You took the whole thing, Mom. Your ass is mine now."
She pushed back hard. "Fuck it. Fuck my ass like you own it."
I started thrusting, slow at first, then harder. The slap of skin on skin filled the room. Her asshole gripped me like a fist, hot and slick. Every time I bottomed out she let out a guttural sound that went straight to my balls. I reached around and shoved two fingers into her pussy while I pounded her ass. She came almost instantly, screaming into the pillow, her whole body shaking, her asshole pulsing around my cock.
I didn't stop. I flipped her onto her back, pushed her knees to her chest, and drove back into her ass. Her tits bounced with every thrust. She looked up at me with glassy eyes, mouth open, spit on her chin.
"Harder," she begged. "Use your kinky mom's ass. Fill it up."
I gave her what she wanted. Long, deep strokes that made her whimper. I spat on her clit and rubbed it while I fucked her. She came again, squirting a little, soaking the sheets. Her asshole never stopped clenching.
When I was close I pulled out, flipped her back to doggy, and slammed in one last time. I unloaded deep in her ass, pulse after pulse, filling her until it leaked out around my cock. She reached back and held her cheeks open so she could feel it dripping.
Afterward she stayed on her knees, ass in the air, letting my cum run down her thighs. She looked over her shoulder, smiling like the satisfied slut she was.
"Next time," she said, voice hoarse, "don't wait so long to ask."
I was already getting hard again.
