The heat hit them the second they stepped inside the private sauna. Sweat already beaded on skin before anyone sat down. Mark dropped his towel first, cock hanging heavy between his legs, and stretched out on the top bench. His wife Lisa followed, peeling hers off and spreading her thighs so the warm air could hit her shaved pussy. Their daughter Emma, twenty-one and already flushed, tossed her towel aside and climbed up opposite her dad. Their son Jake, twenty-three, shut the door and let his own towel fall, his thick dick already half-hard from the sight of his naked family.
"Fuck, it's hot in here," Jake muttered, sitting next to his mom. His eyes locked on Emma's tits, nipples tight from the temperature.
Lisa reached over and wrapped her fingers around his cock, stroking it slow and firm. "Yeah it is. Get hard for me, baby." She pumped him until he was fully stiff, thumb rubbing over the head, spreading the first bead of precum.
Mark watched, dick twitching. "Emma, come here." She crawled across the bench on hands and knees, ass up, and took her father's cock in her mouth without hesitation. She sucked him deep, cheeks hollowing, spit dripping down his shaft while he gripped her hair.
Jake groaned as Lisa leaned in and licked the length of his cock, then swallowed him down. Her mouth was wet and hot, tongue working the underside while she bobbed. He reached between her legs and shoved two fingers into her cunt, pumping them hard.
She moaned around his dick, the vibration making his balls tighten.
Emma pulled off Mark's cock with a wet pop and straddled him. She sank down in one smooth motion, taking every inch into her tight pussy. "Goddamn, Dad, you're thick," she gasped, rocking her hips. Mark grabbed her ass and thrust up to meet her, skin slapping loud in the small room.
Lisa pulled Jake's cock from her mouth and climbed onto his lap facing him. She lined him up and dropped down, impaling herself on her son's dick. "Fuck yes," she hissed, grinding her clit against him. Jake sucked one of her nipples into his mouth, biting lightly while he fucked up into her.
The sauna filled with the sounds of wet fucking and heavy breathing. Emma rode her dad faster, tits bouncing, sweat running down her stomach. Mark reached between them and rubbed her clit in tight circles until she came hard, pussy clenching around him, a sharp cry echoing off the walls.
Lisa was next, bouncing on Jake's cock, her juices running down his balls. "Don't stop, fuck your mom," she ordered. Jake gripped her hips and slammed up, driving deep until she shuddered and soaked him.
Mark pulled out of Emma and stood. "On your knees, both of you." Lisa and Emma dropped to the bench, side by side, asses up. Mark shoved back into Emma while Jake took his mom's cunt from behind. They fucked them hard, the two women kissing each other messily, tongues sliding together while their fathers pounded them.
Jake pulled out and pressed his cock against Lisa's asshole. She pushed back, taking him in her ass with a low moan. Mark did the same to Emma, stretching her tight hole until both women were getting fucked in the ass, fingers in their pussies, moaning into each other's mouths.
Sweat poured off everyone. The heat made every thrust slicker, every slap louder. Mark came first, flooding Emma's ass with thick ropes of cum. Jake followed seconds later, pumping his load deep into his mom's ass while she rubbed her clit and came again.
They collapsed in a sweaty pile on the benches, cum leaking out, bodies still twitching. Lisa reached over and stroked Mark's softening cock. "Round two after we cool off?"
Emma grinned, licking Jake's cum off her fingers. "Fuck yes."
