Much better for Peter the second time

"Well, hell, then c'mon, join the party!" Billy Royce told Peter. He thrust deep into Sally, paused, and bent forward, reaching back to spread his buttocks.

Peter grinned at the rockstar's display, showing off his heavy balls, thick cock root and the lube-slick anus which had just been filled with Jim Walker's long slim cock. This time he was ready. He knelt between Billy's feet and touched the covered tip to his target.

"Come on in," Billy said.

There was a breath from the onlookers in the cruise ship bedroom. Peter's dad Jim, his girlfriend Sandy, and Sandy's big sister Peggy watched Peter set up for a second try.

Peter pressed forward. "Ahhhaaawww," Billy sighed. "Yeah."

Sally laughed. "You got bigger," she said, feeling Billy's shaft swell inside her.

"Shh, don't give away my secret," Billy said. "How's it feel, Pete?"

Peter's cock was enveloped in a smooth, warm sleeve, a snug ring squeezing his shaft. He clenched his hands into Billy Royce's soft buttocks, feeling the firm muscles underneath.

"Amazing," Peter said.

"I love it," Billy said. "You're the perfect size. You ready, Sally?"

"Yes!" Sally said.

"Get rockin', Pete," Billy said.

"Uhhhh," Peter said, rocking his hips and thrusting into the rockstar's ass. "Uhh yeah."

"Ah, Peter," Sally said. "There you go. Yes, do it, sweetie." She let her head droop down. "Oh, Billy, that cunt-buster, oooooh."

Billy said, "That's right. Fuck my cock right into your mama. Yeah, that's the way!"

Peter picked up his rhythm, thrusting faster and faster into Billy's ass. Billy urged him on. Sally muttered obscene praise to both of them.

And this time it was Billy's turn to lose it. His cock swelled inside Sally. He let out a long, throaty moan. His pelvis rocked back and forth with a flurry of orgasmic thrusts and he shot a big load into Sally's cunt as her son's cock pounded his ass.
