Jade paused in the hall, noting with a small thrill that Penelope’s door was open. She could still hear Henry’s snores in the adjacent room. Creeping down the stairs she checked her phone, noting a calendar alert to take her hormone shot, as well as a message from her girlfriend. She decided to leave both until after caffeine. Reaching the kitchen, she began making herself some coffee.

“Jade is that you?” a flirtatious voice cooed from the dining room.

“Yeah, just making some coffee, want some?”

“Sure, yeah. Thanks,” Penelope said, from the doorway. 

Penelope was completely naked, as it was her turn in the weekly rotation. The harsh fluorescent light of the kitchen didn’t do her justice, but the sight was still captivating. She was a head shorter than Jade, with short bright green hair styled in an intentionally unkempt look. She had a round face with warm dark eyes, which presently held a knowing smirk. Her pose, leaning with one elbow bracing her against the door frame, drew the eye to her breasts; small and perky, but with well enough volume to squeeze. On her belly, a line of hair led down to a thick tangle of the bush that concealed her vagina. 

Jade, in contrast, was simply wearing her sleeping outfit of a tank-top and panties. The bulge in her underwear shifted as she beheld her sister. The coffee maker gurgled which snapped her out of the entrancing sight. 

“You want cream and sugar?”

“Just the cream,” Penelope sauntered up to Jade. She grabbed her by the growing bulge and squeezed. “Preferably from the source!” 

“Ha ha. Let me get some coffee before we do that. Do you actually want cream?”

“No, just some sugar. You’re certainly up earlier than normal. I hardly ever see you before I have to leave for school.”

“I’ve been up since like fuckin 3. Deadlines.” Jade poured both mugs, putting some sugar in Penelope’s and a splash of cream in her own. “But now I’m caught up enough that I don’t have to worry as much. Hopefully I’ll start sleeping better, that backlog was no joke.” She handed Penelope her mug and they both marched into the dining room.

“I’m glad you’re up now though. Thursday mornings are so boring now that Henry has later classes. I’m all undressed-up with no place to go” Penelope grinned, pleased with her wordplay. 

“How was your band’s show? I wanted to ask you yesterday but you seemed exhausted.”

“Oh it went great. Crowd loved us. The band we opened for, we were hanging out with them before and I gotta tell you something wild”

“Oh, do tell”

“Ok, so the bassist for the band we opened for, her cock’s huge. Like yours is normal sized, yknow, proportional. Hers is like, I dunno, like a beast.”

“And how do you know that? Did she show it to you?”

“Well my lead singer, Khadija’s her girlfriend. She was bragging. Like ‘check out how hung my girl is’ type shit. She had pictures too.”

“And her girlfriend’s okay with that?”

“I mean if I was that hung I’d want everyone to know. I’d scream it from the rooftops. I’d use it to win any argument ever.”

Jade smirked. She affected a nasal voice, “excellent point, however; 9 inches, soft.” she mimed pushing glasses up. 

Penelope giggled. “Honestly it looked even bigger than that. It was like,” Penelope put her hands flat against each other, measuring out roughly one-and-a-half hand lengths. “Wait her hands are bigger than mine, probably like,” she readjusted, putting her hands end-to-end, base of palm to fingertip, measuring out two full hand lengths, “however long that is?”

“Girl is built like a hentai character”

“I know, right? Kadija’s a lucky woman.”

“And ms. hugecock was in the room for this conversation?”

“Yeah she was super flustered but I could tell she was flattered. She didn’t want to show it off right then because we were about to go on. I think Khadija does this a lot.”

“That’s cute.”

“I knoww, right”

The sisters’ conversation lapsed. Jade took another sip. 

“I’m ready now. If you are, that is. She’s no 15-incher but I think she’ll do the job.”

Penelope smiled mischievously and gave a mock salute, “always ready to do my duty!”

Penelope slid off her seat under the table and crept toward her prize. She gently pulled the front of Jade’s panties down, revealing her cock. Taking hold of the panties, she pulled them all the way off, Jade moving her hips and legs to aid. 

“Hi there” she whispered to the cock, like a beloved pet. “Is little Gocky horny and wants to play? Ooooh.” She licked the still-soft member from base to tip in one well-practiced motion. She then took her sister fully into her mouth. 

Jade groaned in pleasure. Penelope was swishing her tongue around against her frenulum, a favorite of Jade’s. She could feel herself hardening. Jade leant back to enjoy the show. 

Once Jade was properly erect, Penelope released her sister’s cock. She spat on it and started stroking. With her off hand, she started fondling Jade’s balls and massaging her perineum. Penelope then abruptly took her sister into her mouth again, pushing the cockhead as deep down her throat as possible. 

She held it there for a couple seconds, and released again, with a ragged gulp of air. She spat again on the cock, this time the spit was thicker and phlegmy. 

“God you’re so fucking sexy when you do that,” Jade moaned. She ran her fingers across Penelope’s cheek.

“Anything for my favorite sister,” Penelope gave that devilish grin again. She moved Jade’s hand to the top of her head. Jade obliged by taking a fistful of Penelope’s verdant locks. Penelope started sucking again in earnest, soon the entire kitchen was filled with the musical “ghlk ghlk ghlk-s” of loving fellatio. 

It was to this scene that Thomas Krier, the youngest of the Krier siblings, arrived. Holding a bowl of breakfast cereal, he sat down as far away from the lovemaking sisters as was feasible. Jade noticed him and gave a wave.

“Good morning Tom! How did you sleep?” Jade had to raise her voice over Penelope’s ongoing blowjob. 

Thomas very pointedly ignored her. He looked instead at his phone as he ate. 

Penelope paused her administrations. “Hi Tommy!” she shouted, waving her hand above the table before resuming.

Unbeknownst to Penelope, Jade could see Thomas roll his eyes. He continued to scroll on his phone, purposely not looking at what was going on in front of him. 

“Aw, are you jealous? Only a month and a half left for you! Can’t wait for the big day!” Jade cooed encouragingly. The family rule was that no sexual contact could be made between siblings until all participants were at least 16 years old. This was to ensure that every party was sexually mature enough to understand what was happening. Thomas was 15, and had grown increasingly jealous of his family’s fornication as the fateful day approached. 

Thomas fixed Jade with a glare. He stood up from the table, his bowl finished, and stalked back into the kitchen. Jade smiled to herself. She would have to talk to him later. Maybe she would give him another pity handjob. Her heart went out to him. She and Penelope hadn’t stuck to the letter of the rule when they were younger, but not even mom and dad knew about that. Henry hadn’t seemed to be bothered by it, but he was much more successful in non-incestuous pairings than his younger brother. It must be so hard, to be surrounded by acres of fruit that he was not allowed to touch. 

Jade was pulled out of her pity by a tightening in her groin. Penelope’s expert mouth was about to tease out an orgasm. Jade took a tighter hold of Penelope’s head, taking control as to put her over the edge. As she repeatedly slammed her sister’s head into her crotch she groaned, “Penel… oh I’m… I’m cumming!”

Jade pushed Penelope’s head all the way to the base and held it there. She shuddered and curled her body forward around Penelope’s head. Her muscles flexed over and over until she pushed back, releasing Penelope and sinking limp into her chair. 

Penelope arose from the floor. She spat Jade’s incestuous load into her coffee. “Finally got that cream!” she laughed, wiping her eyes. 

Jade chuckled, half in stupor. Penelope leaned over her and gave her a deep kiss. When she eventually broke it off, a line of cummy spit linked their mouths for a moment.

“Even when you haven't showered in days, you still taste 10 times better than either Dad or Henry. How is that?”

“I don’t know. Probably the estrogen, I’d imagine.”

“What a wonderful set of chemicals.”

“Hey can you pose next to my dick? I wanna get a picture.”

“Sure thing!” Penelope kneeled back down, holding the soft cock in her hand she pressed her lips to the side and gave a peace sign. 

Jade snapped the picture. She then opened the message from her girlfriend, Yuuko Torres, which read “gn love”. Jade sent the image she had just taken of Penelope, following it up with, “guess who just got her dick sucked! missing you! <3”. She set the phone down and imagined Yuuko reading it, all the way in Chicago. Yuuko was perfect. Yuuko understood Jade’s family, in fact she seemed to get off to it vicariously.

Jade took a final sip of coffee, draining the mug. She looked to Penelope, who was still savoring her cum-spiked beverage. 

“You done with that?”

“Nope. Thanks though.”

Jade pushed her chair back and took her mug to the sink. Her panties still lay where Penelope had dropped them, so Jade made this journey naked from the waist down. As she rinsed her mug she heard a familiar voice from the doorway behind her. 

“Hello girls!” Stephanie Krier, the matriarch of the Krier clan, glided into the room. 

Stephanie Krier cut an imposing figure. Her hair was cut into a sharp bob that framed her pale face. Her eyes were the same brown as Penelope’s, but while her daughter’s brought to mind warmth, her own were cold, bringing to mind the deep brown trunks of a Siberian Fir. She radiated confidence, the look she gave Jade and Penelope this morning was the self assured look of a woman who had molded this family to her liking, and found it good. Perhaps this confidence was what brought her so much success as a therapist, the feeling that she could take one look at you and know you better than you have ever known yourself. Even just her presence made Jade want to stand up a little straighter. 

“Hi mommy! Good morning!” Penelope excitedly embraced her mother. Penelope had never seemed to feel the intimidation that most people felt in Stephanie’s presence. 

“Good morning, Penny,” she looked over to Jade at the sink and smiled, “looks like Jade got to you first.” Stephanie grabbed a handful of Penelope’s ass, “good girl for doing your duty. I’m very proud,” Stephanie pulled her daughter into a deep kiss. 

Penelope closed her eyes and pressed her naked groin against her mother. Stephanie obliged and extended her leg, bracing herself against the table. Penelope started humping her mother’s leg in earnest, moaning into the kiss. Stephanie tightened her grip on Penelope’s ass, guiding her back and forth along her thigh.

Stephanie broke off the kiss but didn’t stop. Laying her head upon Penelope’s shoulder she continued to grind Penelope’s pussy on her thigh, her other hand caressing Penelope’s face, which was lost in pleasure. Penelope’s voice squeaked with every thrust,  her own orgasm clearly mounting. 

When it seemed like Penelope was about to go over the edge, Stephanie suddenly stopped. Penelope continued to try to grind to the end but Stephanie’s firm grip stilled any hope. Stephanie’s thumb found its way into her daughter’s drooling mouth, forcing their eyes to meet. She grinned evilly.

“Go get dressed, honey. I don’t want to make you late.” Stephanie lowered her leg.

Penelope mumbled something incoherent, unable to form words with her mother’s thumb in her mouth. Jade doubted she would have made much sense regardless, with her cheeks flushed and eyes clouded with pleasure like that. 

“Go on, you have to go to school now.”

Stephanie released Penelope, who stumbled away, her pubic hair mussed at unusual angles, soaked with need. As she took her leave, Stephanie slapped hard on her ass, leaving a red handprint on the milky cheek. Stephanie looked at Jade, who had been watching the whole thing all transfixed, and smirked. She wiped the slick juices off her thigh, along with the loose pubic hairs stuck in it. 

“Enjoy the show?” Stephanie chuckled as she approached, putting a finger against Jade’s cock, half hard after witnessing a master at work.

“You’re so good at that.”

“Years of practice.” 

Stephanie gave Jade a look, implicitly asking if she wanted to have another sexual encounter that morning. Jade gave a slight shake of the head and Stephanie acquiesced, removing her hand from her daughter’s genitals. The understanding was that those ‘on duty’ implied consent through their naked presence on their assigned day. No still meant no, but any sexual activity could be initiated with an on-duty family member. Everyone knew each other's limits, which were routinely renegotiated as needed. This was one benefit of having sexual partners who one has grown up with, there is an innate understanding of one one’s partner likes and doesn’t, of what lines are suggestions and which are hard nos. 

“Tommy better be up,” Stephanie mused, acting as if the past few minutes had not happened. She moved to the coffee machine to pour herself a cup.

“I saw Tom earlier, he’s probably pouting in his room again.”

“That poor boy. It’s not too long though. Maybe after his sweet 16 he’ll cheer up.”

“Here’s hoping.”

The rest of the morning was less eventful. Stephanie and Jade saw out Thomas and a still-flushed (now fully clothed) Penelope, off to another day at Cadwallader High School. William, their father was next, followed by Stephanie. Henry was later, his singular community college class on Thursday started at noon. Jade worked from home, and had retreated to her bedroom/office after seeing off her two youngest siblings.
