Sucking and talking

Peter Walker sat on the couch in his family's cruise ship suite. He looked down at his lap, wide-eyed at his mom Sally who was sucking his cock. Sally looked up from time to time at her son, seeing how he was getting along. Hank Menard, half of their parents' longtime swing partner couple, was sucking on Peter's balls.

Beside Peter sat his girlfriend Sandy Wise, who had developed a "sex friends" relationship with Peter's mom and dad at a series of swing parties before she'd met Peter. She hugged Peter around the shoulders and watched the grownups -- well, the real grownups -- sucking her boyfriend's cock. Behind them stood Jim Walker, Peter's dad, his hands on Peter and Sandy's shoulders, and to the side sat Veevee, watching her husband Hank at work on Peter's balls.

"Pete," Sandy said.

"Uh-huh?"

"Do you think you'd play with your mom if we went to the parties again?" Sandy asked.

Sally came up for air and gave Sandy and Peter a broad grin. "I'm game," she said. "But I have no shame."

Jim laughed. "And I love you for it, Sal," he told his wife.

"Gosh, Sandy, I d-don't know," Peter said, his breath ragged. "Mom, you're so good."

"Mm-hmm-hmm," Sally hummed. She took a breath. "Do you think you'd do me?" she asked Peter.

Sandy took a deep breath and looked at Peter. "Would you?"

"Mom?" Peter said.

Sally looked up at Jim, who grinned, shook his head and shrugged.

"Would you eat me, baby?" she asked Peter.
