Peter takes Hank all the way as Gary watches

Gary's vision narrowed to the center of the action. Peter's butt muscles pumped steadily as he thrust his cock in and out of the experienced man in front of him. Peter's pink balls were tightly clenched against his cock root, moving slightly as each thrust bottomed out with a slap of skin on skin. Below Peter's thrusting cock, his partner's thicker cock root trailed down to a ruddy, blond-haired ball sack whose heavy balls swung freely with Peter's thrusts and whose three-quarter erection bounced up and down. Dad's heavy balls that had fathered Gary and Lil. Dad's thick cock, swinging with Peter's fucking, that had traveled dozens of miles thrusting in and out of Mom, Jim, Sally, and all the other people Dad had nailed over the years, shooting deep inside their hot cunts and asses thousands of times.

He squeezed Bernie's hand. He wondered if he and Bernie could be the same kinds of partners as his mom and dad, each other's best lovers and each other's wingman and cheerleader with others.

"You okay?" Bernie whispered.

Gary swallowed. Yeah, it was fair that Dad took a turn on the bottom sometimes. Gary wasn't sure he felt okay with it for himself. "Yeah," he whispered. "Dunno if I could, like dad."

"I could help you get started," she said. "Mom is really good with that too."

Gary felt a warm flush. "Yeah, maybe."

Peter and Hank's voices rose together as Peter picked up the pace of his thrusts. Hank's grunts were low but full-voiced. Peter let out a loud panting breath with each thrust.

"Yes, baby, yes!" Sally Walker cheered her son. "Give it to him! Fuck his ass good!"

"Ohh-hh, oh-hhh," Hank sighed. His cock swelled and stiffened.

"Finish him, Pete, stop, use your hand now," Jim coached his son.

Peter thrust in deep and reached down with one hand, gripping Hank's thick cock shaft and stroking up and down.

"Ohhhh," Hank sighed.

"Jack him, baby, get him, get him!" Sally cheered.

Peter stroked faster.

Gary watched his dad's cock root twitch and swell. Hank's heavy balls tightened and rose toward his thick shaft.

"ArrrrAHHHH!" Hank groaned. His cock root pulsed and he shot seed through Peter's stroking hand. "Fuck!"

"Oh!" Peter cried as Hank's ass squeezed his cock.

"Ahhh, ahhh, ahhh!" Hank moaned as he shot come onto the towel-covered chair.

Peter's balls twitched. "Yeahhh," Gary said under his breath. "Pete." He remembered Peter's ass squeezing his cock, that last time before the cruise.

"Baby are you gonna come in his ass?" Sally said to Peter.

Gary trembled, his cock hard, watching his best friend about to lose it up his dad's ass. "Pete!" he blurted out.

"Uhhh, uhhh, yeah Gary?" Peter said.
