In the bedroom, on round two

Kathryn headed toward the shower off the Walkers' master bedroom, looking for Peter and Jim to tell them to get the blueberry muffins while they were still warm.

The shower was off, but still warm and steamy, the ventilation fans humming to slowly dry off the big walk-in space. There were several grab bars on the wall. Kathryn frowned. Were those assistance bars, or were those more where you'd want to grab if you needed to keep your footing during sex?

A sound behind Kathryn rose above the fan noise and drew her attention to the bedroom proper. She paused in the door, her heart beating fast at the scene.

A towel was spread over the top of the bed. Peter was on his hands and knees. Behind him, his father Jim held Peter's trim buttocks and fucked into his ass with a fast, steady stroke. Kathryn's angle was from behind Jim, where she could see Jim's tight, ruddy balls moving in and out over Peter's tighter, brighter pink ones. Their breaths came fast, quick pants through their noses.

As Kathryn watched them going at it, she noticed that Jim's cock root and balls were shiny with thick white liquid. Peter had already been up his dad this morning, and this was round two!

Jim's cock root swelled and his balls twitched. "Getting close, Pete," he said.

"Yeah dad, do it!" Peter urged.

"God I love you, Pete!" Jim said.

"I love you too Dad!" Peter said.

"Here goes, here goes! Haaaaaaaaahhh!" Jim groaned. His cock root and balls pulsed as he let loose into his son's ass.

Jim held still for a moment, then withdrew. Father spooned up behind son and lay on the towel.

"I'd do this every morning if Sandy would let me," Jim said.

Peter laughed. "I think she'll give you a few goes. This week anyway. Then she's got me to herself."

Kathryn fled, leaving Jim and Peter together.
