Sandy Wise, Peter's girlfriend, gave Gary the squeeze

Gary turned his head around. "Th-thanks," he said.

It was Sandy Wise, Peter's girlfriend. "Peter loves it when I play with his balls," she said. "Just like his dad." She gave Gary a smile. Sandy was blonde, but with softer, rounder curves than Peter's mom Sally. Not as round as Bernie or Joyce, though.

"Oh," Gary said.

"Glad you joined the party," Sandy said. "I was hoping you'd be game."

Sandy had gotten to know Jim and Sally first, at their swingers' parties, before she'd met Peter. Not knowing who his parents were, Sandy had taken Peter to her favorite running sex party. Gary figured that must have been some scene.

"Yeah," Gary said. "Nothing to hide now."

Sandy smiled. "You gonna come over tonight?" she asked. "Gotta warn you, it might be wild."

"Wilder than this?" Gary asked.

It had been an afternoon-long sex party at the house of Gary's family, in both the living room and Hank's office, leading up to everyone together watching the last two figures -- Peter fucking Hank Menard up the ass to mutual completion, assisted by Gary's hand squeezing Peter's balls, followed by Gary mounting Peter, with Gary's orgasm assisted by Sandy's helping hand.

"He knows," Jim Walker told Sandy.

On the cruise, Peter had started having sex with his mom and dad. Come over to our place tonight, and you'll see, Jim had said.

Gary nodded. "Yeah," he told Sandy. "Give me a sec. Pete?"

"Okay," Peter said.

Gary eased out slowly.

"Thanks," Peter said. "Gonna miss you when we're on the next trip."

"Yeah?" Gary said.

"Yeah," Peter said. "One more week to nail my ass before me and Sandy fly the coop."

Gary laughed. "Guess I better get on it," he said.

"I love you boys," Sally said. Peter's mom gave them a broad smile. "See you after dinner, Gary?" she said.

"Yeah, me and Bernie," Gary said.

Sally laughed. "And you heard Peter," she said. "Only one more week to nail my son up the ass. I want to see you boys together again." She raised her hands in front of her, facing down to cup imaginary buttocks. "Mmh, mmf, mmf!" she grunted, thrusting her hips forward.

Gary's cock twitched. "Yes, ma'am," he said.
