He walked into the kitchen after midnight, eighteen and home from his first semester away. His mom stood at the sink in a thin tank top and panties, the light catching the curve of her ass as she rinsed a glass. She turned, nipples hard against the cotton, and smiled like she already knew why he was staring.
"Fuck, Mom," he said, voice low and rough. "You been waiting up for me dressed like that?"
She set the glass down and stepped closer, tits swaying. "Maybe. You gonna do something about it or just look?"
He grabbed her hips and pulled her against his hard cock. She felt it through his jeans and moaned, grinding once. His hands slid under the tank top, squeezing her heavy tits, thumbs rubbing her nipples until she hissed.
"Bedroom's too far," she said, already tugging his zipper. She dropped to her knees on the kitchen floor and pulled his cock out, thick and leaking. Her mouth was hot and wet, lips stretching around him as she took him deep in one go. He fucked her face, hands in her hair, watching spit drip down her chin onto her tits.
She stood, bent over the counter, and shoved her panties aside. "Put it in. Now."
He slammed into her pussy in one thrust. She was soaked, tight, gripping him as he pounded her from behind. The sound of skin slapping filled the room. Her tits bounced against the counter with every stroke. He reached around and rubbed her clit hard, making her curse and push back harder.
"Harder, baby," she growled. "Fuck your mom like you mean it."
He did. He fucked her until her legs shook and she came with a low, dirty moan, pussy clenching around his cock. He didn't stop. He pulled out, spun her around, lifted her onto the counter, and drove back in. Her legs wrapped around him. Sweat slicked their skin.

He sucked on her nipples while he thrust, biting just enough to make her gasp.
She reached down and stroked her own clit while he fucked her. "Gonna fill me up? Want to come in your mom's cunt?"
That pushed him over. He buried himself deep and came hard, pulsing thick ropes inside her. She kept rubbing herself, coming again around his cock, milking every drop.
They stayed locked together, breathing heavy. She kissed him rough, tongue sliding against his.
"Round two in my bed," she said. "And this time you're eating this pussy first."
He carried her there, already getting hard again.
