The steam hit them the second they stepped inside the private sauna room.
Mark, 42, stripped off his towel first, his thick cock already half-hard from the heat and the sight of his wife Lisa, 40, dropping her robe. Their daughter Jenna, 22, followed right behind, tits bouncing as she sat on the wooden bench, legs spread. Their son Tyler, 24, was last, cock swinging heavy between his legs.
"Fuck, it's hot in here," Jenna said, already sweating. She reached over and grabbed her brother's dick without hesitation. "You getting hard already, bro?"
Tyler grinned and pushed her hand away only to shove two fingers straight into her pussy. "You're wetter than the fucking steam, sis."
Lisa watched her kids start fingering each other and felt her own cunt throb. She climbed onto Mark's lap facing him, grabbed his cock, and sank down on it in one smooth motion. "Goddamn, that's what I needed," she groaned, riding him slow and deep while the heat wrapped around them.
Jenna leaned back against the wall and pulled Tyler between her thighs. "Eat your sister's pussy, little brother. Make me come before Mom does."
Tyler dropped to his knees and buried his face in her shaved cunt, tongue working her clit in fast, sloppy circles. Jenna grabbed his hair and ground against his mouth. "That's it, fuck yes, just like that."
Mark's hands were full of Lisa's ass, spreading her cheeks while he thrust up into her. "Look at them," he grunted. "Our kids are nasty as hell."
Lisa turned her head to watch Jenna's tits bounce as Tyler licked her. "They get it from us. Fuck me harder, baby. I want to come watching them."
Jenna came first, legs shaking, juices running down Tyler's chin. She pulled him up and kissed him hard, tasting herself. "Your turn. Fuck me."
Tyler bent her over the bench and slammed his cock into her from behind. The wet slap of skin filled the small room along with the heavy breathing and moans. Jenna pushed back against every thrust. "Deeper, fuck me deeper, bro. Wreck that pussy."
Lisa came next, cunt clenching around Mark's cock as she rode out her orgasm. She climbed off and pushed him toward their daughter. "Your turn with Jenna. I want to watch you fuck our girl."
Mark didn't hesitate. He took Tyler's place and drove his cock into Jenna's dripping hole. She moaned loud. "Daddy's dick feels so good. Stretch me out."
Tyler moved behind Lisa and bent her over the opposite bench. He slid into his mother's pussy in one thrust. "Mom's cunt is so fucking tight."
The four of them fucked like that for long minutes, bodies slick with sweat and steam, the sound of skin slapping skin and wet cunts taking cock echoing off the walls. Mark pulled out of Jenna and fed his cock to her mouth. She sucked him clean while Tyler pounded Lisa from behind.
Lisa reached back and spread her ass. "Tyler, put it in my ass. Fuck your mother's ass while your dad uses Jenna's mouth."
Tyler spit on her hole and pushed in. Lisa groaned around the stretch. "Yes, fuck that ass, baby. Give it to me."
Jenna pulled off Mark's cock and turned around, offering her ass to her father. "Don't forget about me, Daddy. I want it too."
Mark worked his cock into her ass while Tyler railed Lisa's. The two women faced each other on the benches, kissing and moaning as father and son fucked their asses raw. Sweat poured off all of them.
Mark came first, pumping his load deep in Jenna's ass. She pushed back and took every drop. Tyler followed right after, filling Lisa's ass until it leaked out around his cock.
They didn't stop. After a quick rinse under the cold shower in the corner, they went again. Jenna rode her brother's cock while Mark fucked Lisa's mouth. Then Lisa and Jenna got on their knees and took turns sucking both men until they were hard again.
By the end they were all sprawled on the benches, cum leaking from every hole, bodies exhausted and satisfied. The steam kept rising around them.
"Best family vacation ever," Jenna panted, fingers lazily circling her clit.
Mark laughed, already getting hard again at the sight. "Round two in ten minutes. Nobody leaves this room until we've all come at least three times."
They didn't.
