She had just stepped out of the shower when I walked in on her, towel slipping from her fingers. Water still beaded on her skin, running down the heavy curve of her tits and over the soft swell of her belly. I froze in the doorway, cock already thickening in my shorts at the sight of her bare ass and the dark patch of hair between her thighs.
"Close the door," she said, voice low and steady. No panic, no scream. Just that quiet command that made my pulse hammer.
I shut it. The lock clicked. She turned to face me, nipples stiff from the cool air, and looked straight at the bulge I couldn't hide.
"You're hard for your mother," she said, stepping closer. Her hand reached out and cupped me through the fabric, squeezing once, firm and deliberate. "Been thinking about this for a while, haven't you?"
I nodded, throat dry. She didn't wait for words. Her fingers tugged my shorts down and my cock sprang free, thick and leaking at the tip. She wrapped her hand around it, stroking slow and tight, thumb smearing the precum over the head.
"First time doing this with your mom," she murmured, dropping to her knees. Her mouth opened and she took me in, lips stretching around the shaft, tongue hot and wet as she sucked me deep. I groaned, hips jerking forward. She took it all the way to the back of her throat, gagging once, spit running down her chin onto her tits.
She pulled off with a wet pop, stood up, and pushed me toward the bed. "On your back. Now."
I lay down. She climbed over me, straddling my waist, and reached between us to guide my cock to her pussy. She was already soaked. The head nudged her entrance and she sank down in one smooth motion, taking every inch until her ass rested on my thighs.
"Fuck," she hissed, rolling her hips. "Your cock feels so good inside me." She started riding, slow at first, then harder, tits bouncing with each thrust. I grabbed them, squeezing, pinching her nipples the way she liked. She leaned forward, hands on my chest, and fucked me faster, clit grinding against me.

"Don't come yet," she ordered, voice ragged. She lifted off, turned around, and sank back down reverse cowgirl. I watched my cock disappear into her again and again, her asshole winking above it. She reached back, spread her cheeks, and moaned when I pressed a thumb against that tight ring.
"Put it in my ass," she said. "First time for both of us like this."
I slicked my fingers with her pussy juice and worked one, then two into her ass while she kept riding my cock. When she was loose enough she lifted off, positioned my dick at her asshole, and pushed down. It was tight, hotter than her pussy. She took it slow, breathing hard, until I was buried to the hilt in her ass.
She rode me like that, ass clenching around my shaft, one hand rubbing her clit. I thrust up to meet her, balls slapping against her. Her moans turned into sharp cries.
"Fill your mother's ass," she gasped. "Come inside me."
I grabbed her hips and slammed up, unloading deep in her ass, pulse after pulse. She came with me, fingers flying over her clit, pussy dripping onto my stomach. She stayed seated until I softened, then eased off and turned to kiss me hard, tongue tasting of both of us.
We lay there breathing, sweat cooling on our skin. She reached down and stroked my cock back to life.
"Round two," she said, spreading her legs. "This time in my pussy again. And you're going to eat it first."
I moved between her thighs and buried my face in her wet cunt, tongue lapping at her clit while my fingers pumped into her. She came on my mouth twice before I slid back inside her and fucked her slow and deep until we both finished again.
That night became the first of many. No guilt, no hesitation. Just raw need every time she wanted her son's cock.
