Jake came home from the gym and stopped dead in the hallway. His mom stood at the kitchen counter in those tiny hot pants, the denim cut so high the bottom curves of her ass cheeks spilled out every time she moved. The fabric stretched tight over her hips and crotch, outlining every fold. She was barefoot, tank top thin enough to show her nipples.
"Damn, Mom," he said, voice already rough. "Those shorts again?"
She turned, wiping her hands on a towel, and gave him a slow smile. "You like them? They make my ass look good, don't they?"
He didn't answer with words. He crossed the room, grabbed her hips, and spun her around so her belly pressed against the counter. His hands slid down and squeezed both cheeks hard through the hot pants. "Fuck yes they do. You've been teasing me with these for weeks."
Linda pushed her ass back into his grip. "Then do something about it, baby. Pull them down and fuck your mom."
Jake yanked the shorts down in one rough tug. They caught on her thighs for a second before he got them to her knees. Her bare ass was right there, smooth and round. He slapped it once, watching the skin jiggle, then dropped his own shorts. His cock sprang out thick and already leaking.
He didn't bother with fingers. He lined up and shoved straight in, burying himself to the balls in one thrust. Linda gasped and braced her hands on the counter. "That's it, fuck me hard.

Use that big dick on your mother's cunt."
He started pounding right away, hips slapping against her ass with wet, filthy sounds. Every thrust made the hot pants around her knees strain tighter. Jake reached around, found her clit, and rubbed it fast while he fucked her. "You feel so fucking wet. You've been walking around in those slutty shorts waiting for this, haven't you?"
"Yes," she moaned. "Every time I put them on I think about you bending me over. Harder, son. Wreck me."
He pulled out, spun her to face him, and lifted her onto the counter. The hot pants were still tangled at her knees. He spread her thighs as wide as the denim allowed and slammed back inside. The angle let him go deeper. Linda wrapped her arms around his neck and met every thrust, tits bouncing under the thin tank.
"Talk dirty to me," he growled, pounding into her. "Tell me what you want."
"I want my son's cum," she panted. "Fill my pussy up. Make it drip down my legs while I'm still wearing these fucking hot pants."
Jake's rhythm turned brutal. The counter shook. He buried his face in her neck, biting the skin while he drove into her soaked cunt again and again. Linda came first, clamping down around him, nails digging into his back as she cried out. He followed right after, groaning loud as he pumped thick loads deep inside her.
They stayed locked together, breathing hard. Jake finally pulled out, watching his cum start to leak from her. He tugged the hot pants back up her thighs, letting the fabric catch some of the mess against her skin.
"Leave them on the rest of the day," he said. "I want to see my load soaking through when you walk around."
Linda smiled, still catching her breath. "Whatever you want, baby. They're yours now."
