Attending a pool party, without going swimming

Marcus and Cassidy stared at Anna's bouncing butt while she led them on a tour of the house. Occasionally she'd do a half-turn, letting her massive hard-on spring into view for just a moment before continuing on. Both of the twins were walking awkwardly, now... And judging by the expression on Trixie's face, she was just as turned-on by the futa girl's teasing.

One of the highlights of their tour was the photo wall in the living room. "All hand-developed by Mom," Anna said, as they passed a board with dozens of photos pined to it.

Marcus leaned in to take a closer look, and saw that most of the photos were nude--No, not just nude: in several of them, two or more naked bodies were locked together in all sorts of positions, smiling at the camera as they--

"Hey, c'mon! I know they're great, but the live show's waiting out back," Anna teased, beckoning her guests onward. "But first... Costume change!"

"Huh?" Marcus tore his eyes off her crotch long enough to see that she was pointing down the hall.

"Strip down--It's a pool party, remember? Trunks are okay, I guess, but whatever floats your boat. Bathroom's over there, second on the left... Hurry up!" With that she skipped off toward the backyard, still stroking her cock.

A few minutes later, Marcus and Cassidy emerged from the house. The boys were dressed only in their swimsuits--But their jaws dropped when they saw their hosts, who were wearing even less.

Anna was lounging on a deck chair, with her phone in one hand and her cock in the other. Her eyes were hidden behind a pair of stylish sunglasses, but she was clearly checking out the shirtless twins: she jerked off faster as they walked out onto the patio, licking her lips.

Meanwhile, Alison was climbing out of the pool. Unlike her daughter, she wore a bathing suit... If you could truly call it that. Her micro-bikini top had barely enough fabric to hide her nipples, and the flimsy straps allowed her heavy breasts to bounce freely as she made her way up the ladder. As her lower half came into view, the boys saw her specially-made thong. Despite the pouch in the front, it struggled to contain even her flaccid meat.

When she saw Marcus and Cassidy, though, that small token of modesty disappeared. With a single twitch, her half-hard cock pushed aside the front of the thong and flopped down against her thigh.

"Hello, boys," Alison said cheerfully, grabbing a towel off the second deck chair and beginning to dry off. "I like your bathing suits... But I'm afraid the 'swimming' part of the day is over!"

"I, uh..." Cassidy cleared his throat, his eyes jumping between the gorgeous futas. "...Sorry, what?"

The MILF just giggled in reply, taking a seat beside her daughter. A bright-pink cocktail in a tall glass was sitting in the cupholder, and she took a long drink as the boys stared at her body.

After a few moments of tense silence, Marcus tried to break the ice: "Wow, it's a hot one," he mumbled. "Could we get a couple of beers? Or something?"

"Or something," Anna echoed him, glancing at her mother. "You can drink as much as you like... As long as it's cum."

Marcus's eyes went wide, his lips parting involuntarily. Before he could think of a reply, the patio door slid open behind him.

All heads turned toward Trixie as she pranced outside. The lithe teen was naked from head to toe, wearing nothing but her piercings: one in each ear, one on her lower lip, and two more on her nipples. Neither of the twins had seen the latter ones before, and for the first time since they arrived, they went almost ten consecutive seconds without glancing at a fat futa cock.

The hosts let out a cheer when they saw that Trixie was naked, and she struck a pose in response. "Sorry I'm late," she giggled nervously, hands on her hips. "I brought a bathing suit, but then I thought about it for a while, and--"

"--And you made the right choice," Alison purred, grinning. Her cock was at full mast as she rose to her feet. "Come here, honey... Boys... Make yourself at home."

With that she threw her towel on the patio, giving it a little kick to spread it out. Her daughter stood up as well, standing side-by-side with her mother... A pair of futa bombshells, with their massive dicks at attention.

The brothers hesitated, but Trixie didn't. Pushing past them, she fell to her knees on the towel. Then, sensing the boys' hesitation, she patted the spots beside her. "C'mon, guys," she hissed, more embarrassed by their hesitation than the fact that she was kneeling nude in front of two women she barely knew (not to mention her boyfriend's brother).

It didn't take much prompting to get Marcus and Cassidy kneeling as well. The moment their legs touched the ground, their heads were grabbed--Gently, but firmly.

"I guess this one's mine," Anna tittered, moving Cassidy's face slowly towards her swollen cockhead.

"And this one's mine--No complaints," Alison replied, doing the same to Marcus. "We'll share Trixie, then?"

"Mhm," the excited girl answered, already diving in.
