First a little lube and preparation

Sandy Wise whispered to her boyfriend Peter Walker. They laughed quietly together.
"Sure," Peter told her.

"Let's make sure you're ready, honey," Veevee Menard told her husband. "In case Peter wants another go at you."

"I won't argue," Hank said. He bent over the playroom bed at his wife's direction and held his buttocks spread for her. "Ahhh." He sighed, feeling Veevee squeeze a cool spurt of lube up his ass. She wiped around the outside, leaving it moist and clean, and finished with a kiss. Hank chuckled. "Taking lessons from Sally?" he said.

Beside them, Sally Walker was working on Hank's son Gary along with Gary's girlfriend Bernie. The curvy, curly-haired brunette followed Sally's directions as she added another squirt of lubricant inside Gary's ass.

"Too much lube is almost enough when you're going up the butt," Sally said. The tall, slim blonde gave Bernie a big smile as they worked on Gary together.

Bernie laughed. "Yeah, that's what I always told my old girlfriend Habiba. She usually said, 'Stop being your mom!'"

"She should have thanked you," Sally said. "Mmmm." She looked at the young man's butt. Gary had been her son Peter's secret lover, but Peter had never had a turn on top. That was going to change now. Her smile returned, even wider now, and she laughed. "Nice heavy balls, like his dad," Sally commented to Bernie. "Does he last a long time with you?"

"Sometimes," Bernie said, and smiled at Sally.

"Oho!" Sally said. Bernie and Sally laughed together.

"Mom, could you help me out?" Peter said.

Sally joined Peter and Sandy to check on Peter's preparation. Sally made sure that Peter was cleaned up and lubed inside, saving the last splash for right before the men put themselves together. "You look ready, Peter. But let me take a closer look. Come round with me, Sandy."

Peter's mother and his girlfriend got down close to his behind to take a good look. Peter's balls were pinker, and their sack looser and smoother than Gary's. But Peter took after his dad in having a quick recovery.

"Mmm, balls could be tighter," Sally said. She opened her lips and sucked in her son's balls, then released them. "Oh, better not go too far." She nuzzled higher and kissed his ass, which twitched. "Mmm-mmm," Sally said, and laughed. "Now you," she told Sandy.

Sandy turned and kissed Sally's lips, tasting a little slippery-sweet lube and natural bitterness from Peter's ass on his mother's lips.

"No, no, kiss Peter!" Sally said, her wide mouth broadening in another smile.

"I'm so glad we can be lovers again," Sandy said. Sandy had hooked up with Peter's mom and dad at a series of sex parties and didn't know that Peter was their son until she and Peter started dating steadily. When Sandy found out, she'd stopped playing with Peter's mom and dad. Until this week, when Peter started.

Sally lowered her voice and whispered, "I'm glad too. Jim and I missed our favorite fuck-bunny. But now you're back, and you brought Peter with you." She returned Sandy's kiss, finishing by swirling her tongue-tip around Sandy's lips. "Now your turn with Peter."

Sandy kissed Peter's balls, which were starting to tighten up, and went down on his ass, tasting the same slippery-and-bitter that she had tasted on Sally Walker's lips. Peter's ring twitched and pulsed under her tongue strokes. So many times it had opened for Gary's cock. Just this week, for Peter's father Jim's long shaft. And just today, for Gary's dad Hank Menard, with his big-headed, thick cock like Gary's.

Peter sighed. "That's so good, Sandy," he said. "Oh!" Sandy had stiffened her tongue and pressed inside.

"Hh-huh," Sandy said indistinctly. She chuckled, her tongue still inside Peter. She held up a hand. Sally snapped the tip off another little tube of lubricant and handed it to Peter's girlfriend. Sandy withdrew her tongue slowly and teasingly, making sure Peter felt it, then inserted the nozzle and freshened up the slippery coating.

"That was great," Peter said.

"Excuse me a minute," Sandy said. "That slippery stuff feels weird on my tongue." She stepped into the bathroom.

Bernie and Gary had their heads together, talking quietly. Sally cupped her son's balls and whispered in his ear. Hank and Veevee sat side by side, looking at their naked son and his best friend/lover lying prone, showing off the lines of their backs and buttocks. Hank's cock twitched as he looked forward to connecting with Peter again. Jim sat a bit to the side, watching and waiting, gently stroking his cock, looking forward to Peter finally getting turnabout with Gary.
