Someone wants to test her holes out

Peter did a doubletake, at first not believing what he just heard.

"I'm sorry, sir, could you repeat that?" Peter asked.

"I said, do her holes work?" Said some guy, "like, what kind of things can she take up the ass?"

"First off: she's my dad, and I don't know why you would want to-" Peter cut off as he feels something warm, soft, and squishy rub against his thigh.

"I would be more than happy to give you gentlemen a demonstration of this body's 'capabilities,'" said Walter in a low, sensual voice, currently squishing Samus Aran's fat buttcheeks into Peter's legs. "But perhaps we should take this somewhere more... private?"

A few minutes later... (In the SpongeBob narrator's voice)

"Dad why are we following these strange guys to a dark and creepy ally behind the expo?" Peter asked his curvy father, who seemed absorbed in gyrating his hips back and forth.

"Hmm? Oh, why? To have butt-breaking sex with them, of course" said Walter, "how else am I going to test this body's elasticity function?"

"Oh yeah that makes sense," replied Peter, shaking his head at his dad's sluttiness, "why didn't you just get me to help you test, instead of blue-balling me all night?"

"Because I need your semen output to be at it's best," he said, bending down to unzip the suit, and then spreading his wobbling asscheeks at the two men who had stopped to listen. "Okay boys, come and get it!"

Without hesitation they both start playing with Walter's naughty bits, sinking their hands deep into Samus' pale buttcheeks, sticking a finger or two into his plump bootyhole.

"Come on!" Said Walter,"if I wanted you to finger me I could have done that myself. Actually fuck me! Destroy my slutty asshole!"

The two guys looked at each other, shrugged, and preceded to punch their fists against Walter's trembling anus with all their might, failing to penetrate it at first as their fists bounced off the tight, puffy orifice.

"When I say destroy my ass I don't mean lightly slap it," Walter said sweetly, wagging her butt back and forth at the two men. "Peter, can you pull down your pants for me?"

Peter obliged, unbuckling his belt,(which he tied around his dad's neck) before pulling his jeans and underwear down, revealing his growing footlong hard-on.

"Okay while these kind gentlemen fist my ass, I need you to brutally **** my face hole," Walter said, barely flinching as another punch bounced off his seemingly steeltight sphincter.

"Okay dad, you're the boss," said Peter, before hooking his thumb into Samus' mouth, and shoving his subway-sized schlong down his dad's throat, bulging out her neck to nearly twice it's normal diameter. Meanwhile, the two goons at the rear had finally gained a foothold(literally) in the ironbounded anus that had denied them entry long enough.

Walter went crosseyed and glurked around his son's cock, feeling one guy working his shoe into his backdoor, stretching the plump ring of muscle around his booted feet, while the other pried at the entrance with two hands.

"Glrsh, glurk," gagged Walter, feeling his son go deeper into his throat, past his collarbone, shunting his heaving tits aside, before finally bursting through his esophagus and entering Walter's stomach.

The guy with his steel-toed boot up Samus' buttpussy was slowly rotating it clockwise, then counterclockwise, grinding it against the slimy, convulsing walls of Walter's rectum. The other guy succeeded in working both his hands into the stretched-thin, straining sphincter, and was pulling it open as wide as it would go, leaving Walter feeling like he just sat on a fire hydrant.

Back to the front, Peter was having trouble holding his load back, bucking forward until his hairy groin smashed into Samus' nose, then pulling all the way back, stopping right before his grapefruit-sized glans left his dad's gaping maw. His dad was apparently a world-class throat-goat, sucking and running her long tongue over Peter's balls when they got close enough, wrapping it around them on the forward trust, and even teasing Peter's asshole with it.

The two in the back were having a field day with Walter's seemingly unbreakable butthole, the guy footing Samus in the ass having lost his shoe on one particularly deep, gut-bulging thrust, so he got down on his back and preceded to stomp both feet into the hungry, gaping anus in front of him. This **** Samus to lie down on her stomach, Peter's dick almost slipping out, but getting caught on her front teeth. It dragged him unexpectedly down, and he stumbled, losing his footing, before falling down onto his dad, his cock sliding back into her stomach, and Peter himself getting a face-full of foot-fucked ass.
