"I think I know what Mom's test is."

"We still don't know if Mom is actually testing us."

"Hear me out," Seay smiled at his twin. Their faces weren't terribly alike, but their smiles were. She smiled back, but with one eyebrow crinkled skeptically.

Seay sat up. They'd been laying still on their backs, heads together, fully (Tracy) and mostly (Seay) nude bodies sprawled in opposite directions. Now Seay was upright from the waist up with his back to his sister. He peered over his shoulder at her. She looked asleep. He sipped from his mug. The coffee was still hot. When he set it back down, the steam swirled up into the morning light slanting in through the window between their beds. It occurred to him that steam looked somehow more sentient when it was in sunlight. As it rose, it was like it was just waking up. Probably wondering what that funky smell was. That would be the twins' pheromones. God. It just kept being crazy to him: he was in an active, ongoing, incestuous relationship. Two if he counted Mom. But still, what he had with Tracy was particularly special. Real-feeling. Heck, sometimes he could even will it to feel 'normal'-feeling.

"I'm listening," Tracy murmured.

"Huh?" Listening to him? Sometimes it was like she could read his thoughts. This wasn't unheard of in twins, except Seay never could seem to guess what was going on in Tracy's messy, covertly kinky brain.

"Your theory," she yawned. "Mom'sszzzz test," she stretched.

"R-right. Yeah." He shook his head. What had they been talking about? Oh, yeah. The test. "So... so Mom knows. About us. Right?"

"Uh-huh," Tracy nodded, her eyes closed.

"And yet, she's somehow okay with it."

"I'd say more than," Tracy said.

"More than okay with it."

"She drank my pee."

"Right," Seay blinked. He had also let Tracy pee on him yesterday. Did his sister have a secret pee fetish? "But so. Uh. Then if there's a test, and I feel like we might as well assume there is, since even if there isn't - "

"We still come out in her good graces."

"We - yeah. Nice," Seay chuckled, and accepted Tracy's request for a backwards laying-down high five. Slap.

"But so what's the test?"

"We can't have sex."

"Oh, so you mean the most obvious possible thing."

"Says the girl who was one layer of cotton away from raping me."

"Don't use that word." She tilted her head back and shot a disgusted look at him. "I'm not joking."

"Shit. Okay. Sorry."

"I'm serious," she scoffed, but relaxed again. "Anyway! If we can't frick, right, then I guess ... do you wanna sixty-nine?"

"W-what?"

"I mean," Tracy talked with her hands. She spoke up at the ceiling mostly, but occasionally craned her head back to look at her brother. He was sipping his coffee so slowly. She'd practically chugged hers. "We've already done basically everything else. And you're saying Mom secretly doesn't want us to have sex. Even though she's cool with drugs and incest. But so. By process of elimination. Next thing on our itinerary is sixty-nine, right...?"

"Itinerary?"

"Do you not want to?"

"I mean, I do. Yeah. Obviously. But like... I hear it's pretty overrated."

"What's not to like? You clearly enjoy my p-word. I clearly enjoy your 'COCK,'" Tracy air quoted, reminding him it was him who told her to use that (occasionally admittedly somewhat jarring) word.

"I guess I'm just pretty sure we're going to be, like, bad at it."

"Uh-huh. Tell me, how am *I* the twin who can never seem to get her shit together, and yet I'm also the one who isn't afraid of putting in a little practice?"

"You would ... want to 'practice' sixty-nine with me?"

"Maybe I, like, ate part of you in the womb or something."

"You would seriously do that?"

"Well, not like on PURPOSE," Tracy frowned up at the ceiling. She flicked her hands like, WTF. "I mean, I was a fetus. But it does sound like something I'd do, yeah."

"I mean, you'd 'practice' with me," Seay clarified, his utterly authentic smile unphased by his sister's capacity for cannibalism.

"Oh," Tracy blinked. She rolled over so she could perch on her elbows and look up at him. Ooh, and because the chaturanga felt nice. "I mean, if you think it wouldn't count as failing Mom's test."

"She taught me how to eat you out."

"Lickies. I prefer to call them lickies."

"Lickies, for real? Are you a Sesame Street character now?"

"I want us to practice lickies and suckies so we can learn how to cum in each other's mouths at the EXACT same time."

"..." Seay opened his lips to respond, but didn't have a comeback.

Tracy cackled proudly. She'd blown his circuit.

"Knew you wanted to!" she sang, and sprang up onto all fours. "Lay down you big handsome idiot!"

"I'm finishing my coffee."

"I'm going to piss on this carpet if you don't lay down this instant."

"You are not."

"I am not joking. I've got a full tank. You saw how fast I drank my coffee."

She lifted one leg to the side, like a dog about to mark a bush.

"I just scrubbed this carpet yesterday. If you even squeeze a single drop of pee onto - "

"How could you possibly stop me?"

"!" Seay knew in an instant what she was up to. "You are goading me into cunnilingus."

"First of all, gross. It's lickies. And second of all, I am goading you into suckies as well." She crawled up behind him, now, and draped an arm over his shoulder. She caressed his left pec. She circled her fingertip around his right nipple. She nibbled his nape. "You're good at it. I promise. Just finger me while you suck my clit, and I can cum really fast." Her voice's breath warmed his neck and raised shivers up into his scalp.

"But if I'm focusing on you, how can I also, like... focus on what you're doing?"

"Are you asking me how to 'focus' on receiving a blowjob?"

"I - " Seay faltered. He blinked. He sighed. He set his coffee mug down again. He laid down on his shoulders.

"Yay," Tracy nodded. "Now lie still. I will bring her to you."

"Underwear off?"

"If you would be so kind."

"It's just... kind of hot when you help."

"Fine," she shrugged. "I can help. But I'm sitting down first."

"Sitting wh-?" Seay began to ask, when his sister straddled his face midsentence. She was right above him, her crotch and butt and pussy and asshole and tailbone and all of her right above his mouth. Then she sat. She settled. And here she was, sitting on his brain. He opened his eyes to a view of her towering spine, lower back dimples and, blurry in the extreme foreground, her squished-apart butt cheeks. She'd plopped directly on the center-line of his face, so that the tip of his nose was snuggly nestled in her taint, his lips - still in the 'oo' shape at the start of the word 'where' - now puckered against the slippery inner workings of her spread-apart labia. His hands had been ready to help catch her in case her full weight cracked his skull or dislocated his jaw, but it turned out his skull and jaw were both perfectly strong enough to fend for themselves, and she meanwhile had ex-gymnast balance. He was fine. She was fine. And now she was patting him on the hips to remind him to lift so she could help remove his briefs.

She pulled his underwear all the way off. They caught briefly on his foot.

"Hup," she said, and popped his foot free.

And now he was naked. She was on top. And her p-word was on his mouth.

"Alright, big boy," Tracy said. "Come to Mommy." She leaned forward. "Or, well, come to Sissy, I guess. Since now we have to differentiate."

"Nnnf," Seay groaned. His face was full of vagina. He was completely and complexly smothered. It was like every wet, warm, sticky, and slippery part of her underside was trying to find a new home on his tongue.

"Oooh," she groaned. "Oh, Seay. This was such a good idea."

"Ffffff," he moaned.

"You are the best at lickies," she assured him.

She wiggled her hips. She played with his somewhat flaccid cock, teased it and pawed at it, watched it literally squirm like its own sentient little organism. She play-bit it. Seay didn't even gasp. Oh, yeah - he couldn't. But so she did it again, a little harder. This time he jolted underneath her. She giggled breathily and murmured an apology, then licked the place where she had bit him. Then she suckled on it. Then she got really, really horny and shoved his whole cock into her throat.

His cock continued to harden inside of her, and her tongue could feel the warm blood surging through its veins. It tasted like him. She enjoyed his cock.

"Mmm," Seay groaned. "Ghhhhk. Rff."

Being on the bottom was a little daunting for Seay. HIs sister's pussy wasn't just intensely juicy right now, but it also made him salivate profusely. Nevermind that her anus was right there again, almost literally enveloping his nose, and didn't NOT smell like what it was. The whole of her, altogether, quite literally ON his mind, all of her all at once. She flooded him in every sense of the word. Drenched him inside and out.

Especially once things started getting humpy and grindy - neither twin could fight the bodily impulse to 'fuck' the other's mouth - Seay's challenge grew downright harrowing. Sometimes she'd clamp his whole entire face in the wet, boiling hot dark of her hindquarters. He would be unable to breathe. Unable to think. Unable to do anything but lick and suck and slurp and gulp and try to hold out hope for oxygen whenever next she relaxed her ass and hips and legs again.

So she came quite a few times before Seay came once. And it wasn't simultaneous by any means. In fact, she had kindly slumped off of him to give his poor, beat-red, dripping wet face a rest, and was now just kind of half laying across his lower abdomen, woozily, dreamily, avidly with her head kind of resting on him, stroking and milking and sucking her brother's cock. She sighed and hummed and groaned intermittently. Then at one point, she nuzzled him, maybe just to be cute, but it triggered a sudden concussive blast of semen across the side of her face, onto the folds of her ear, into her hair, and halfway up her brother's stomach.

"Sorry," Seay gasped. "I... I didn't realize that would happen."

"How many times have I cum on your face today?"

"Y-yeah, I... lost count."

"So shut up. We're fine."

"Okay," he said. "We're fine. It's just each other's cum."

They lay there together for a minute or two, panting and recovering, her hand still wrapped around his spent, sticky cock. She squeezed.

"Don't," he begged.

"Sorry," she laughed. "I just love you."

"You too."

"Yeah?"

"Duh, Sis."

"Awwww," she cooed, and smooched him on the cock. But gently this time.

"Sis?"

"Yeah, Bro?"

"I'm kind of covered in cum. Mind, uh, letting me grab a tissue?"

"You don't want me to lick it off?"

"W-well. N-no? I mean. I wasn't expecting you to. Like. Y-you don't have to - "

"MLEM!" she lapped loudly, vocally, at a big salty splat of cum just south and east of his navel. She smeared it onto her tongue. Then she showed it to him. "Want thum?" she offered.

"No thanks."

"Thure? It'th good."

"S'all yours, Sis."

"Mmm, call me Sissy."

"Sissy."

"Tell me you like when I give you suckies then clean you up."

"I... really appreciate it."

She paused between licks. "Whennn?"

"When you suck my cock and then eat all the cum off my body."

"Say it how I said!"

"I'm allowed to say it however I want."

"Fine. Then you're allowed to clean yourself off, too, jerkwad." She sat up, reached over to his nightstand, and grabbed the box of kneenex. He reached his hand up to take a couple. She threw the box at him instead.

"H-hey, come on!"

"I need to pee for real," she grunted, suddenly feeling an urgent pressure, and clambered hurriedly down the ladder.

Seay had to shuffle sideways on his back to reach the tissue box where it had landed after caroming off his nose without letting his own cum dribble off his stomach and onto the carpet. He carefully extracted a couple of tissues. Using his arms made his abdominal muscles tighten and bounce. The cum began to drool down his hip. He caught it with the kleenex just before it hit the dry glistening carpet fibers. He filled that tissue. Then another. And by the time he was dry, he had a little handful of gloopy, smelly, wadded up tissues to throw away. He sort of waddle-crawled on one hand and two knees to the mini lidded trash can, popped it open, and tossed in his deposit.

"So listen," came Tracy from behind him.

Seay stayed where he was. Kind of at the opposite end of the loft from his sister, who still had her feet on the ladder. He could only see her upper body. It was lovely. She was the prettiest girl he knew. She really, really was.

"I know we're brother and sister, and so we're used to like, kind of being equals or whatever."

"Uh-huh..." Seay frowned. Where was she going with this?

"But when I'm being sexy with you, what I want is what I want. Okay?"

"... And what you want is?"

"For you to do what I fricking say."

"I... see."

"You... see." Tracy mocked him. She even dropped her voice and tried to make a more masculine face. Then she dropped the act and scoffed prettily. "You feel me, though?"

"I... think I can get with that. Sure."

"Yeah?"

"But then what do I get in return?"

"Ohmygod," she rolled her eyes, finished climbing the ladder, and cat-crawled through the sunlight to her brother. "You get ME you fricking nimrod." She put her hand on his thigh. She kissed him on the lips. She crawled up his front-side until he teetered backwards. He fell with double the usual body weight onto his back, and with his sister's tongue inside his mouth. It knocked the wind out of him - and into her. His breath puffed her up like a bellows. It even made a sort of sound as it rushed into her through her voice box.

She was glad she'd emptied her bladder before coming back up here.

"I love you," she whispered, their faces close.

"Love you," he breathed.

"Good." She sat up. She straddled his cock. "So. Want to keep practicing until Mom and Dad get back?"

"Y-yeah. Sure. Let's practicing. Keep - I mean. Keep practice. Ing..."

"That's the spirit."

She kissed him again, then turned around on all fours so that her pussy was to him again.

"You on top again?" he asked.

"That a problem?"

"I mean, no? But... is it what you want?"

"It lets me control the pressure," she nodded, and wiggled her butt at him. "But if you don't think you can HANDLE the pressure... "

"I can handle it."

"Can you?"

"Come here."

He grabbed her by the hips and tugged her ass-first into his mouth.

"Ffffrick," she whined. She came almost immediately. She melted onto him. She lapped at his cock. It was right there. She clutched his hips, set her weight, and began truly fucking his face. Once she felt certain he and her were on the same page - rhythm, check; rhyme, check - she refocused her vision on the hard, horny cock pointing patiently at her face.

"S-sis?" he gasped from below.

"Mhm," she hummed.

"I need to... I mean I really fucking want to ... to have sex with you."

"Nmyeah?!" she suppressed a laugh. "Th-that so?" Gosh. He was even still feasting on her between beats. Insatiable lunk. He was clearly having a hard time thinking straight. She was so fricking here for it. The carpet beneath her was almost certainly going to need another deep clean. Her brother's face, too.

"Y-you wanna just say fuck the test?" Tracy asked.

"I think I'm - gonna have to - y-yes," he panted.

God she liked him a lot.

"You're so horny," she moaned with full-hearted approval. She had to stop licking his cock. If she didn't, she'd bite it again. Like, hard. By accident. And he had such a nice cock for biting. She glanced down between her own dangling little tits at her brother's wet, sticky, juicy, hungry chin. She could see his tongue muscles bulging as he licked and probed the deepest, weirdest parts of her p-word. "I am too," she told him. She couldn't stop grinding her butt on his chin. But she did for just a second, to let him speak.

"I... I am aware," Seay grunted. His jaw was starting to cramp. He knuckled at the sorest little pebble-hard spot, felt it shift, and saw stars in his vision as the soreness exploded into weirdly painful relief. "I can barely keep up with this thing," he said, and gave her a pat-pat on the ass.

"If we fuck, we can never take it back," Tracy warned him. She was getting close. He had her almost all the way there. "This will be our last chance to stay regular, b-boring old twins."

"T-Trace," Seay spluttered. "If you're serious...? I can't think straight about us AND lick you at the same time. Can we stop and discuss this?"

"Ugh, sure. Why not." She pressed her p-word down one more time onto his mouth, then slid herself free of his lips. Her juices smeared his cheeks and drizzled from his nose. His saliva thoroughly slickened her entire groin area. She wiped her crotch on the nearest blanket and spun around. Now her face was where his had been. And he was looking up at her, his expression a strange mixture of adoration, frustration, and horniness.

"I don't know if you're just high on my p-word fumes or something, but you should know I am absolutely fricking ready to bone you," Tracy said. She smooched him on his nose. His face smelled like her strongest smells. SO hot. "I mean make love to you," she added for clarity, and kissed him again more sweetly this time, on the mouth.

"B-but the test..." Seay sighed as his sister kissed his cheeks, his nose, his forehead. "W-wait. Are you, like, cleaning me?" he chuckled.

"Uh-huh," she said and then licked his jaw. She was savoring how her juices tasted on his face. It wasn't the same as just licking them off her fingers.

Down below, her hips gyrated ungovernably, mashing and swiveling her hot, juicy hindquarters all over his naked, raging erection.

"Ffffff - " Seay wheezed. He grabbed his sister by the hips. She didn't stop humping him. If anything, having his hands holding her like that only gave fuel to her lower half's flame. Now she ground with purpose, truly pulverized his steel-hard shaft with her pelvic bone and clit and cunt. She sat up, now, put her hands on his hands on her hips, and held them there as she all but fucked him. God, how it felt. How it felt to sit right on his hard cock. He knew, now. She gazed fondly at him, not even quite smiling, sort of idly smirking, eyes half-closed, cheeks pink, and when he noticed her staring at him, she didn't even blink. She just chewed her lip at him, and squinted a little, and watched his expression morph and pucker in direct response to each little thing she did to him.

"F-ffffff..." he stammered, and his hands spasmed, gripping and relaxing. He didn't want her to stop. "Oh, God, S-Sis...!"

"It's okay, Bro," she cooed. She took his hands off her hips, one by one, and brought them up to her boobs. "It's okay to fail." She held him by the backs of his hands and made him grope both of her tits at the same time. "Ohhh frick that's good," she whimpered.

"M-Mom is... sh-she's going to - "

"If the test is about love and connection and whatever," Tracy hugged him with her legs, her ass, her weight, as he squeezed and fondled her tits, "then we are passing with fffff-flying ffffff-fricking COLORS!" she gasped, and a deluge of new hot moisture slicked the friction between them.

"Ohmygod, ohmygod," Seay groaned, "are you cumming on my COCK?"

"Uh-h-h-huh," Tracy cringed, clamped her eyes shut, and squeezed her brother's hands so hard against her tits she left nail indents in his skin, as another orgasm rocked through her.

"O-okay," he said. "Okay. Fuck it. FUCK it."

"Yeah?" she laughed breathlessly, and opened an eye to peer down at him. "You want this now?"

"Fuck yes, I want this. I've... I've always wanted this. I've loved you my whole fucking l-life - ohhh, oh, s-slow down. Slow down."
