"Ah, the great outdoors!" Papa Arc said triumphantly, holding his arms outstretched to the sky like a preacher in a sermon. "Remnant is so beautiful that I think we take it for granted!"
"I think a mosquito the size of a pickup just flew by," Jaune said, swatting at the buzzing terror. Mama Arc sprayed a foul-smelling aerosol in Jaune's general direction, causing the blonde boy to keel over coughing. "Mom, what the heck is that?" he managed to spit out between heaving coughs.
"Oh, I bought it at the drugstore. Buzz-B-Gone it's called."
"I call it a toxic nightmare!" Jaune said, wiping his eyes.
"It's not that bad, no worse than those energy drinks you kids guzzle!" Papa Arc said, poking the blazing campfire with a stick. "Now come, it's S'mores time."
The Arc Twins and their Mother took their seats on the large rocks that Papa Arc had dragged over to double as chairs. Per their father's instructions, they had dressed for the 'great outdoors' ' but Saphron had chosen a flannel shirt tied at her midriff and jean shorts that just barely covered her ass. Jaune was in shambles.
It had been torture for him to keep his hands off his sister the entire day. Every time she bent over to tie her boots or get something out of her hiking bag, she made a production to arch her back and toss her ass and hips out. It was maddening. Yes, they would eventually share a tent later that night, but her constant teasing just made the day tick by at the speed of a crippled snail.
"Oops! You got something on your lips, sweetie!" Mama Arc said after Saphron had bit down on a large double-decker S'more she had made. The sweet concoction oozed molten marshmallow on her lips with Saphron wiping the gooey white substance with her index finger and sucking on it, glancing at the corner of her eye at Jaune.
Once again, Jaune was in shambles.
"Delicious!" she said, literally licking her lips.
"It had better be for how much I paid for these!" Papa Arc grunted, tossing another log on the fire. "These marshmallows are made with real sugar, not that hyper-processed corn syrup sugar substitute crap."
"It's definitely one of the sweetest things I've ever tasted!" Saphron said.
The night wore on at a tortuously slow pace. Papa Arc had attempted to scare everyone with ghost stories, but Jaune could barely pay attention with the blood rushing in his ears, an almost dull buzzing that made it incredibly hard to focus. All he wanted was Saphron and soon it would be time to turn in.
"Well, you two should probably get to sleep. I'm going to make us a big Lumberjack breakfast tomorrow and then we're going fishing for dinner!" Papa Arc said, pouring a bucket of water to quench the fire.
"Oh, goodie. Worms," Jaune said, struggling to keep himself under control.
"It's not so bad. I can think of one worm I want on my hook," Saphron said, giving Jaune a playful nudge. He was about to break.
They shared their goodnights and once inside their tent, and double checking to make sure it was zipped up all the way, the twins were on each other. He was on top, passionately kissing her as his tongue explored her mouth, his hands already untying her shirt to claim his prize.
Like a kid on a Winter Holiday morning tearing off the wrapping paper of his gift, he practically tore off her flannel top. Of course, she wasn't wearing a bra and those gorgeous tits were free for his mouth. Kissing down her neck, he latched his mouth onto her left nipple, sucking hungrily on the soft pink flesh, his hands working to unfasten her short jean shorts.
"Jaune…" she whisper moaned, running her fingers through his scraggly blonde hair. "Gods, this feels so good."
He didn't reply, just released the nipple, the tit wobbling back into place, before attacking the other one, trying to fit as much in as he possibly can. His hand slid under the soft fabric of her panties, a long and lanky index finger splitting her lips and wiggling its way inside. Saphron's voice caught in her throat as she held on to him tightly, feeling Jaune slide up to the first knuckle.
"You just love teasing me, don't you?" he said softly in her ear, nibbling on the lobe.
"It's fun getting you all hot and bothered. Makes our time spent together much more interesting."
"I've been pent up all day," he groaned, curling his index finger inside of her sister's wetness. "Gonna fill you to the brim."
It was then Saphron's eyes went wide, not from any sexual bliss, but from a stark realization that hit her hard.
"Jaune! Wait!" she whispered, "We can't! There's no running water! I don't have any way of cleaning myself out and you don't buy condoms anymore since I started the pill."
Jaune stopped fingering her for a second, his face sullen and sad. It had completely slipped his mind too! His Horny Brain was so strong that he had neglected to even consider this.
"Aw, that's right!" he said, slowly pulling his glistening finger out. "I guess we could 69 or something?" but even that didn't feel right.
"Wait, I have an idea!" Saphron said, her face lighting up. "Take off your pants and straddle me, but around my stomach."
Curious, but trusting her, Jaune hurriedly disrobed. His erection was almost angry, pointing at an acute angle, throbbing with the head red and swollen.
"Scoot closer!" Saphron gently ordered as she assumed the position. When she felt he was close enough, she squeezed his manhood between her tits, motioning for him to pump his cock between them.
"Oh, oh this is new!" Jaune hissed, gently rocking his hips as Saphron pressed her breasts over his cock. "Gods, how do they feel soft and hard at the same time?"
She just giggled, craning her neck as best she could to kiss his head, flicking her tongue over the slit to lap up the precious precum.
"Hnngg, Gods, you're an amazing woman, Saphron Arc!" Jaune said, eyes closed. "I don't know what I did to deserve a sister as good as you, but the Gods smiled at me by making us together."
"I could say the same about you, little brother," she said, once again teasingly referring to the fifteen-minute difference between them. "Someday we'll leave this place and stop hiding, just live together as husband and wife."
Jaune just growled, the idea filling his heart with love and his dick with lust. They had no lube, but they didn't need it, as his precum was keeping things slick and smooth.
An owl seemingly hooted its approval in the night air, as a brother thrust his cock between his sister's tits. Back and forth they went in perfect harmony, in flawless synchronization.
Then, without warning, Jaune pulled his cock back from between Saphron's tits, leaving a look of confusion on his sister's face. But she didn't have time to voice her confusion before she saw why. Jaune was close and began to masturbate right in front of her.
Oddly enough, with all the kinky things they had done since they had become lovers, masturbating in front of each other was one of the few things they never really did. It just never crossed her mind to try it. But there was a certain voyeuristic thrill watching him pleasure himself like this. His hand was practically a blur as it traveled up and down his cock.
"Mmm…now this is a nice view," she said, resting her hands on his hips.
"Y-yeah…" Jaune grunted, too lost in the moment. His head was spinning and that tunnel vision of a preorgasmic focus was more and more apparent. "S-Saph…I don't wanna-"
"Shhh!" she said reassuringly. "Don't hold back, my love. Let it all hang out."
"Saaaaaaaaph!" he cried out in a strained, hoarse whisper. Everything seemed to happen in slow motion as Saphron Arc watched her brother's cock fire off like a shotgun, a thick wad of his seed splashing against her face. She yelped in surprise as another blasted her jaw before a few more ropes landed on her collarbone and just barely above her tits. Jaune's head hung low as he was spent, a silly, sloppy smile on his cute face.
"And they said you shouldn't wear white after Labor Day!" Saphron giggled, reaching for a nearby towel to clean herself off. With a grunt, Jaune rolled off of her, Saphron briefly licking his manhood clean before the twins snuggled in a sleeping back together, completely nude.
"We need to do that again," Jaune said, big-spooning Saphron, his arms wrapped around her waist.
"I may need safety glasses, little brother. You almost shot my eye out."
"Good morning!" Mama Arc said, adding logs to the fire. "Did you sleep well?"
"Eventually." Saphron simply said, sipping water from her thermos.
"Your Father went to go catch some fish for breakfast as he forgot to pack the bacon. In the meantime, we have some leftover S'mores from last night! Care for one?"
"No thanks, Mom," Saphron said. "I've had my share of white stuff for one trip."
