When Tracy and Mom got back to the cabin - and stepped out of the car into their mercifully secluded front drive - they peeked in and found the boys lounging around the living room. Seay lay on his stomach on the floor fully naked, reading some book about birds, while Dad stretched his bare hairy body on the couch, his eyes glued to the TV screen, which he'd muted and put on closed-captioning. It was Bob Ross, talking about a squirrel he'd once nursed back to health. The differently shaped pair of differently handsome men looked a bit tired and disheveled. Tracy clutched Mom's arm and begged her wordlessly not to walk in still completely naked. Please. It had not been an experience she wished to have to explain, or relive. Please.
Mom relented. They snuck away to the bathroom to slip into some clean clothes of Mom's that were in the dryer. When they came back out, neither man seemed to notice Tracy wasn't wearing her own clothes. Which was just as well, since she began to remove them immediately.
"Did you guys have sex or something while we were gone?" Tracy asked as she stepped back out of her flip-flops - and shorts, and tank top. "It smells a little post-coital in here." When she was down to just her (i.e., Mom's) panties, she went and sat on Seay. She loved sitting on his big muscly butt. It felt good on her own smaller butt.
"Look who's talking," Seay grunted. "You smell like a barnyard. Did you and Mom fuck in a field or something?"
"Wouldn't you like to know?" Tracy purred, and panty-humped her brother's naked butt.
Mom sighed and followed Tracy's lead, stripping down to her bra and panties, and then finding a seat atop Dad, who was lengthwise across the sofa. Dad grunted as Mom sat down on his midsection. But he didn't look unhappy for the well-shaped load.
"So, did you?" Tracy asked Seay again, a little bit of genuine envy creeping into her voice, even as she ground herself into him a little. Testing his horniness levels.
"Fuck Dad?" Seay didn't even look at her. But she was pretty sure he was rolling his eyes at her.
"Just mouth stuff," Dad admitted proudly. "And yes. Before you ask? It was awesome."
"I'm sure it was," Tracy sighed. "I'll bet Seay really liked that. Did you just love getting to pig out on Daddy's big scary cock?"
"Scary?" Dad frowned, and glanced self-consciously down at his own junk.
"Where'd you guys go?" Seay asked. "You were gone awhile. Did you bring home dinner?"
"The Pattinsons," Mom answered. "And no, but I thought we could order Vinnie's."
Dad looked a little surprised to hear this. She'd gone to see Rob and Kris without telling him. It was fine, but it was odd.
"We owed them for the drugs," she shrugged, sensing Dad's mild confusion. Best to nip it in the bud.
"Did you?" Dad asked, still looking bemused. Mom could be a bit of a minx, sometimes. One never quite knew with her, what she was really up to.
"You're welcome," she announced to the whole cabin. "You all can pay me back later, if you'd like."
Tracy yawned, then stretched. She lay forward across Seay's naked back. She squished her boobs into his rhomboids. God. It felt awesome. Her twin was so big and warm and man-like.
"Later, Mom," she sighed. "Right now, I'm horny for my hunky bro-bro."
"Honey," Dad muttered to Mom. He was hard as a bicycle seat underneath her butt in these pretty lavender lace panties. "I have to tell you something."
"What?" Mom chuckled, her eyes still on the screen.
"I don't know how to put this other than just to say it."
"Say it," Mom purred, and ground her ass on Dad's cock.
"I see our kids laying there sandwiched on top of each other, and I hear them talking about us all having sex together, and I - I don't want it to stop. I hope to God you know what you're doing, sweetheart. I really do. Because this is just about the most perfect thing I could possibly imagine - oh, shoot, for crying out loud, I didn't mean to make you cry!" Dad chortled, and hugged Mom's wracking shoulders tight. "I just meant, I really do love this. And you. And... I'm saying I want to trust you, okay?"
Mom nodded into his hairy chest. Headbutted him, sort of, actually. And smiled the most beautiful smile - even if he couldn't see it, he would be able to tell.
"That goes for you two, as well," Dad said sternly to the twins at his wife's feet. Seay grunted assent. Tracy ignored him. "I said I want to trust you, Trace," Dad reiterated. He nudged Mom. "Hey, poke her in the butt for me, wouldja hon?"
Mom poked Tracy's flexing, humping butt with her left big toe. Tracy noised but did not stop sucking and gnawing on her brother's upper trapezius. His shoulder meat. Her p-word, too, dug over and over eagerly into the hot, humpable rump of him.
"You know," Dad dead-panned, "that'd feel even better if you rolled him over."
"And take those poor panties off," Mom cringed at how aggressively her daughter was mistreating her favorite pair, "before you wear a hole in the fabric."
"Gawwwd just let us do our own fricking thing, would you!" Tracy finally roared, and swatted at Mom's toe before it could poke her again. "He likes when I do this!"
"He does?" Dad snorted.
"It's com-MF-ortable," Seay grunted as his sister hopped forward onto his midback all of a sudden, bellowsing his lungs.
"And you know what else he likes?" Tracy jeered, chucking Mom and Dad a sharpened eyebrow over her bony shoulder. "My stinky." She scooted forward, grinding her sopping wet crotch up her brother's back. "Fricking." She knelt, straddling the air above the back of his head, and with her hands pantomimed snapping her brother's neck; Seay got the directive, and quickly turned over - albeit somewhat awkwardly, as his sister insisted he keep his head between her legs. "Panties," she finished, and -
- swooped down to kiss her brother full on the lips -
- before sitting back up and plowing her full weight Mom-gusset-first into his ready (as he could make it) face. Mom and Dad watched Seay's nostrils flare in that moment between the kiss's departure and the panties' arrival, sucking in a deep diver's lungful. His mouth parted, and Tracy planted her wet, sticky, salty-tart, pantyclad p-word on his tongue. Her face went calm, meditative, blissful. She began to roll her hips, back and forth, and then in little circles. Seay gripped her ass with his hands and pulled her as close as possible, and then he tugged and groped still harder, trying to get her a little closer still. He hated her panties in this moment. Where had she even gotten this pair? He thought he knew all her underwear. Whatever! He wanted them off his face, and off of his sister's potently pungent p-word.
"Tell themmm y-you like it!" Tracy ordered him as she positively pestled herself into his oral mortar.
She felt herself gaping, her muscles melting. His face was so hot, and so wet, and his tongue was squiggling so fervently against the sopping sticky fabric of her mother's panties' crotch.
"Telllll th-themmm!" she whimpered as menacingly as she could.
