Lady, then gentlemen, and then to sleep.

Peter held steady, meeting the rhythm of Sally's pelvic thrusts as she came until Sally finally relaxed and fell back loose and limp into the bed.

Peter kissed Sally. "I love you, mom," he said.

Sally's eyes, the same blue as Peter's, looked back at her son. She gave him a sleepy-eyed smile, her broad lips slack with satisfaction. "Love you too," she said.

Peter dismounted, his hard cock glistening with his mother's clear wetness.

"Good," Sally said. "Heh." She waved to the others. "Your turn." She rolled to her side so she could watch the rest of them while lying down comfortably.

Peter sat up to look around at his girlfriend Sandy and his dad Jim. They had been waiting, watching Peter lay the final strokes into his mother as she got her 'O'.

"Go," Jim cued Sandy.

Sandy jumped on Peter, knocking him to the bed.

"Whoof!" Peter said.

Jim pulled Peter's heels, stretching him out flat.

Sally laughed, seeing her son get the treatment she had just had a few minutes ago. She lazily reached out a hand and closed her fist in Peter's blond hair.

Sandy grinned hungrily at Peter. She had taken her fill of lovely girl sex from Kathryn and Sally since they'd arrived at the Walkers' house. Now she wanted her man. Her men. Jim had been her sex-party lover before she met Peter, before she knew they were family. Sandy straddled her boyfriend's lean hips and paused. Jim took Peter's cock in hand and steadied it for Sandy. Peter sighed, feeling his dad's hand squeeze his shaft. When Jim tapped Sandy's hips, she sat down.

"Mmmm," Jim said. He smiled, watching Sandy's hungry body devour Peter's cock. Sandy had a lovely soft peach of a butt, with Peter's cock as the stem. He was a lucky man, Peter, with a girlfriend so eager, so loyal, and open to sharing.

"Oh!" Peter said as Sandy pressed down, taking him deep.

"Heh!" Sandy said, grinning at Peter. She rose again, working up to a rhythm.

With Sally gripping his hair and Jim holding his legs, Peter was obliged to lie still as Sandy rode his cock.

Sandy closed her eyes and rode hard, pressing down and scrubbing her clit on Peter's pubic bone, then rising and falling on his cock. Her face and ears turned pink as she rose toward her orgasm. Finally she stiffened and ground down hard on Peter, moaning and tilting her head up as she reached climax.

Sally beamed a smile from the head of the bed. She released her grip on Peter's hair, and patted his head gently. Jim let up his pressure on Peter's legs so he could thrust back and answer Sandy's motions with his own.

Sandy slowed, still moving on Peter. "Pete, can your dad be in me too?" she asked.

"Okay," Peter said. His eyes widened. "Have you ever...?"

Jim straddled Peter's legs and scooted up behind Sandy's butt.

Sandy rose up. Jim slicked his pre-come over his cock head and touched it right above where Peter's shaft entered Sandy. Jim smiled, feeling Peter's cock swell at his touch.

"Say go," Jim said.

"Pete?" Sandy said.

"O-okay," Peter said.

"Go," Sandy said.

"Aaaaahhh!" The three of them groaned together as Jim's cock slid in beside Peter's, stretching Sandy wider. There were advantages to the Walker men's long, thin cocks. It felt powerful, beautiful, sexy and strange. Each of them could feel every little throb, squeeze, and wiggle, and every attempt at thrusting or riding.

"You know," Jim said. "This almost works."

Sandy laughed. "It feels great. Except nobody can really move."

"Yeah," Peter said.

"Rain check?" Sandy asked. "When we're not so tired?"

"Okay," Peter said.

"I'd be happy to," Jim said. "Try it from a different angle next time. Okay now..." Jim withdrew.

For a final figure, Peter knelt and entered Sandy from behind. Jim joined his wife again, and they lay on their sides facing the young lovers. Sally agreed to Jim's whispered proposal. Slicked with lube, Jim's cock entered his wife's tight ass for their own final figure, and Jim raised Sally's leg so Peter and Sandy could watch.

Peter fucked his girlfriend, his hands on her hips, his abdomen slapping against her soft buttocks, watching his mom and dad show off in front of them. With Jim's cock up her ass and her leg raised, Sally's beautiful pussy was fully displayed for Peter's gaze. And for Sandy's. Sandy smiled at her future mother-in-law, her lover, whose pussy was so beautiful and delicious.

Jim was first to come, shooting deep up his wife's ass, followed quickly by Peter.

After a brief wash-up, the exhausted lovers headed for dreamland.
