The cabin was buried under three feet of fresh snow when the power cut out. Mark slammed the door behind him, snow still melting off his coat. His mother, Linda, stood by the fireplace in nothing but a thin robe, rubbing her arms.
"Fuck, it's freezing in here," she muttered. Mark dropped the firewood and stared. The robe clung to her curves, her nipples hard from the cold. She was 48, still thick in the hips and tits, the same body he'd jerked off to since he turned 18.
"Get the blankets," he said, voice already rough. They piled every blanket they had onto the couch and stripped down to underwear. No point pretending modesty when the temperature was dropping fast.
Linda crawled under first. Mark followed, pressing his bare chest to her back for warmth. Her ass pushed against his crotch. He was hard in seconds.
"Mark… you're poking me," she whispered.
"You feel too good," he answered, grinding once.
She didn't pull away. Instead she reached back and grabbed his cock through his boxers.
"Jesus, you're big like your dad." Her fingers squeezed. Mark yanked her robe open and filled his hands with her heavy tits, thumbs rubbing those stiff nipples. She moaned and pushed her ass harder against him.
They didn't talk much after that. Mark shoved his boxers down and freed his cock. Linda spread her legs just enough. He slid the head between her pussy lips, already wet despite the cold. One hard thrust and he was buried inside his own mother.
"Fuck," she hissed. "Do it. Fuck me."
He pounded her from behind, skin slapping, the blankets sliding off their sweaty bodies. The cabin stayed freezing but their bodies burned. Linda reached down and rubbed her clit while he fucked her, moaning every time his balls slapped her ass.
"Harder, baby. Fuck your mom like you mean it."
Mark flipped her onto her back, hooked her legs over his shoulders, and drove in deep. Her tits bounced with every thrust. He leaned down and sucked one nipple hard, biting just enough to make her cry out. Her cunt clenched around him, hot and slick.
They changed positions again when she got on top. Linda rode him slow at first, grinding her clit against his pubic bone, then faster, slamming down on his cock. Mark grabbed her ass and spread her cheeks, watching his dick disappear into her.
"Look at you taking your son's cock," he growled.
She came first, shaking and cursing, pussy pulsing around him. Mark didn't stop. He flipped her onto all fours and fucked her through it, then pulled out and shot thick ropes across her back and ass.
They lay there panting, cum cooling on her skin while the fire crackled. The cold crept back in, so they pulled the blankets over them again. Linda reached between them and stroked him hard once more.
"Round two before the sun comes up," she said.
Mark pushed her onto her stomach and slid back inside. This time he took it slower, deep and grinding, whispering filthy shit in her ear about how long he'd wanted to breed her. She came again, face buried in the pillow, and he followed, filling her this time.
By morning the snow had stopped and the power was still out, but neither of them cared. They stayed under the blankets, fucking whenever the cold got too sharp, until the roads cleared two days later.
