Hank pauses to invite Gary to Peter's "Lucky Pierre"

Hank watched his cock disappear into Peter's ass. The young man took Hank's thick shaft easily. Hank looked up at the reason. Peter's mouth was full of Gary's thick cock.

For two years, Hank's son Gary had been pumping dick up his best friend Peter as an occasional break from Gary's rolling pork-fest with women of all ages. But Hank was hardly one to judge. He and Peter's dad Jim had been more than occasional partners in this very crime.

"Ahhh," Hank breathed. "So. Fucking. Good." His shaft slowly sank deeper into Peter's ass.

Gary noticed Peter pause and quiver and heard Hank's voice. Gary opened his eyes to see his father as he knelt behind Peter's butt. Fucking Peter's butt. Gary's eyes met his father's gaze.

"Feels good," Hank said. He smiled, thrusting slowly and steadily.

Gary looked down. Peter's eyes were wide with the sensation of being penetrated by Hank's big cock. Peter moaned. Gary felt a tickle at the root of his cock.

"Dad," Gary breathed. "Oh, fuck."

Hank nodded. "Yup." He eased off his thrusts down to slow motion. "Gary?"

Gary opened his eyes wider, waiting. He sighed as Peter sucked him deeper.

"You know what a Lucky Pierre is?" Hank asked.

Gary nodded.

"Pete asked for one, and invited you," Hank said. "You want in?"

"Mm-hh," Peter hummed, his mouth full.

Gary swallowed. His eyes flashed to Bernie, who smiled. He looked back at his dad. "Hmmm."

"You want top or bottom?" Hank asked.

Peter took his mouth off Gary's cock. "Or middle?"

Gary raised his eyebrows. "Whoa," he said. "Um..."

"Between me and my dad." Peter added. "Either way. Or both."

Finally it sank in. Gary looked down at Peter and up at Hank.

Hank grinned, seeing his son's expression.

"Um..." Gary said.
