# CHAPTER FIVE: WEEK TWO
We return now to James and Ariana, alone together in their dorm, six days after their first visit to The Breeding Machine. Having recovered from the severe discomfort of the first two days, the pair had much to discuss, and much time in which to discuss it. I should warn you, they appear to have grown more comfortable with each other following their experience. I cannot guarantee they’ll be able to resist each other much longer. But at least the water’s back on.
Ari drops her jeans to her ankles, and turns to her brother whilst lifting up her shirt.
“You joining me?” she smiled, disappearing under her top.
Once of the many things discussed over the last six days was just how comfortable they now felt. Including, but not limited to, how they felt comfortable showering together. Perhaps that they even *liked* the idea. Which is gross, of course. Completely inappropriate! But perhaps not as gross or inappropriate as spreading your legs to your brother, presenting your naked pussy, and having him rub you to orgasm with his shaft, separated only by a thin pair of trunks. By comparison, having a shower together felt quite sober.
“I’d never turn you down Ari” James replied with a wink.
Off came him jeans and socks, before flinging his shirt at his sister, which she caught, quite confidently.
“Gonna have to do better than that, bro!” she laughed, pinging her bra back at him.
It sailed over his shoulder, hitting the wall. Her titties bobbed free, clearly thankful for their release. She threw her hand up instinctively to cover her nipples, as he brother removed his boxers and tossed them in retaliation. Unable to catch them with her remaining hand, his underwear sailed straight into her face, to her sounds of playful revulsion.
“Eww! Get off!” she feigned through laughter “and cover your cock, bro!”
A perfectly sisterly reaction to seeing her big brothers semi swing free of it’s polyester prison. Just why was it a semi? Certainly not the inevitability of seeing his own sister naked… surely? She did have some gorgeous boobs, though. It’s not out of the question.
She turned to face away from him as she pulled down her panties. A not-entirely-effective strategy for modesty, as she only framed a perfectly clear view of her little pussy for him between her thighs. In the time it took for her to realise her mistake, he walked up behind her and bent forward, spooning her whilst standing up. Her cry of surprise was a great indicator of the moment his heavy cock swung forward to pat her on the pussy. For a brief moment, she felt her brother part her lips *ever* so slightly, but only with his length, and not at an angle that would have allowed him to slide inside her. The surprise subsided into laughter as they enjoyed the affectionate cuddle. His strong arms supported her from underneath, pressing up along her chest, and in return she threw her hands up and backwards, in an uncomfortable attempt at a reverse-cuddle. All she could do from that angle was grip onto his bum cheeks and pat or tug playfully at them. Unable to escape his arms, she was content with running her own arms back over them. It was a tender moment, a loving cuddle between brother and sister, as his slightly engorged penis continued to rest platonically on her vagina.
As the pair stood, chuckling at his antics, they shared a loving glance. Perhaps it was flirty, considering what he could have done to her in that compromised position. But of course he didn’t! He would never. Protective and cosy big brothers don’t fuck thier baby sisters. Maybe touch genitals while unprotected, sure. Siblings might even make each other cum, that’s perfectly natural. But never ever fuck. Brother-cock inside sister-pussy? That’s just inappropriate.
They made their way to the en-suite shower. With the water running again, they were back to regular showers (albeit slightly more intimate ones).
*squeak*
The water cascaded down her back, casting a spray of warm mist across the siblings. Individual droplets raced down her back and around her plump ass, tracing the lines of her spine like a woodland stream before falling gracefully down her legs. He noticed everything. Every fissure, every line. Ariana truly was a beautiful girl. The mist enveloped them both, like a cloak of privacy. Leaning in behind her, much like before, she felt her big brother’s cock, now noticeably more erect, pressing up against her bum. She pressed back playfully. His hand emerged from the fog into a pocket of air at her side, running up and over her breasts, coming to a firm halt over her neck. She heard him whisper into her ear from just an inch away.
“Pass me the body lotion, baby”
Her hair stood on end. Brother was so sexy when he got dominant. She’d never do anything inappropriate of course, like taking her biological brother into her mouth and sucking on him until he came incest cum down her slutty throat, but she could appreciate his attractiveness in a platonic way. A completely innocent way.
“Yes, Daddy” she whispered back.
He lathered up his sister, running smoothly across her skin with a trail of scented lotion, leaving no inch of her untouched. Around her waist. Around her neck. Across her stomach. The insides of her thighs. Ari felt James’ masculine energy envelop her, comfort her, rubbing her ass against his crotch in a display of requited care and affection.
As the waterfall washed the lather from her shoulder, he kissed her neck, and she instinctively reached behind her to hold her brother by the cock. It was smoothly lathered. Interestingly firm. She loved how it felt between her fingers as she began to pump him, still encased within his warm brotherly arms.
“Fuck” he gasped under his own breath.
She beamed at the confirmation, feeling like a very good girl indeed. In that moment, all she wanted to do was make Daddy happy. It became hard to distinguish what was sudsy lotion and what was creamy pre-cum as they mixed and coated her palm. His grunts of satisfaction only made her want him more.
She stopped, releasing her grip and turning to face him.
“Big brother?” she inquired.
“Yes honey?”
“I have an oral fixation…”
“Ari, we’re not even in the Breeding Machine…”
“Please please *please*!” she pouted “Look how hard I made you! You want a sloppy blowjob from your cute little sister, don’t even lie. You’re teasing me *way* too much, and now I get my reward! I don’t care if it’s incest, I want you to put yourself in my mouth”
With that, she dropped into a squat, and held her mouth open wide, tongue rolling out expectantly. This was another line to cross. The first was inside that glass box, he’d rubbed her over the edge, but that was, in a way, protected. Now she wanted more. Of course she did, the bratty little sister trope, always wanting more… and always getting what they want.
James smiled down at her, running his right hand through her hair. It was a strange series of life events that led him to being in this position, but just look at her adorable face, just asking to be facefucked. He loved her so very much, how could he say no?
Holding her by the back of the head, he leant back, bringing his cock up to her mouth, and pulled her in. Arianas lips slid along his cock, now fresh with water. She felt the water dripping down his body, and just a little masculine sweat, meeting her lips and parting like the tide as she came into shore. Her tongue slid down his ridge, blanketing him from underneath with her warmth. He was now completely inside her mouth. She loved his taste, his form, everything about the sensation made her hairs stand on end as the downpour continued above her, and the steam concealed them from the outside world.
She was entranced. Feeling her big brother’s cock filling her mouth pacified her. Rocking her head back and forth to the sound of his groans was perfect to her. What a good girl she was. Slurping and guzzling, hungry for her brother’s meaty dick. Every convulsion she pulled from him made her feel like a pretty little incest princess.
That’s when she got her hands involved. Supporting his balls with one hand, tenderly rolling them over her palm to enhance the sensation, the other was pulling him feverishly at nearly twice the pace of her mouth.
“Ohhhh… fuuuuck..” he groaned.
Both his hands were in her hair at this point, pulling just as firmly as she liked it. Tugging her into his crotch with sexual desperation, wanting her to finish him off.
And she did.
Looking up at her sexy big brother from an angle most sisters only dream of, the glint of a brilliant idea flashed across her eye. With one swift yet smooth motion, Ariana leant forward onto James, completely and entirely bottoming out his full shaft down her throat. If it weren’t for the steamy cloud around them, you could see his cock pressing on the inside of her esophagus. She resisted the reflex to gag as his thickness dominated her breath and her forehead quite literally pressed up against his lower abdomen.
“OH FUUUCK!”
She felt him twitch, and she knew exactly what was coming. Her own brother. Into her mouth. Ariana really had taken her biological brother into her mouth, and sucked on him until he came incest cum down her slutty throat. Ropes and ropes of his cream leapt down into her stomach. It felt like her prize, being filled up by the man she loved so much. Convulsion after convulsion, gripping onto her hair like handlebars. He could feel his sisters smile in the way her lips felt up against his neatly trimmed pubes. It was a prideful smile, at being able to make her cute big brother so happy; she smiled at every groan, every twitch against her lips, she smiled knowing that *so many* girls only *dream* of giving their hot big brother a sloppy blowjob, but she really made it happen. It went on for what felt like minutes. The siblings were loving every second, completely in the moment, enjoying each other’s enjoyment just as much as the sensation itself. Ari guzzled down *every last drop* of her yummy big brother.
Slowly, the convulsions subsided.
[COMPLETE THIS]
His chunky brother-cock throbbed inside her wet little sister-pussy.
“Does this feel like love, Ariana?” he asked, earnestly.
She nodded up at him feverishly, biting her lower lip as her wide eyes locked with his. She smiled and sighed deeply with emotional satisfaction.
“This feels like love, James” came her reply. The sincerity of her voice was tangible. She felt that deep and loving connection with her brother she had always craved. The tenderness of thier sex filled her soul. The thickness of his shaft filled her hole. It was a sweet and gentle moment, fragile like the fallen feather of a bird flying over head, rocking sideways, back and forth in a cradle of air, landing gently in your palm. The skin on skin contact was so comforting. The incestuous sensation of her brother tickling her pussy from the inside was so pure and wholesome. She could swear, in that moment, if only their parents could see their children, wrapped up in eachothers arms as a beautiful continuous form of human art, they would be so proud. Some siblings fought and called names. And here *they* were, excited to have sex with each other! Brother sister sex! It was so cute! Getting along as well as siblings everywhere hope to (secretly or publicly). A handsome big brother and his pretty little sister, so in love that they share sex with each other, is *such* a beautiful thing. Pure and sweet, biologically-related, grew-up-together, consensual and completely unprotected incestuous sex. No one on this earth loved her more than James, and it just felt so natural to want to share the most pleasurable of experiences with the one who cares for you the most; so natural to give her vulnerable physicality to a real man like her real brother, and to enjoy his physical form in return, his abs pressed up against her stomach, his thick penis resting on the inside of her vagina, his strong but gentle hands holding her so tight. She felt every inch of her tasty big brother caressing her internally, the tip of him visible as a small bump on her waist. She couldn’t wait to get thoroughly fucked by the sweetest, most gentle, most caring big brother in the whole world. He really deserved this pussy after all he’d looked out for her growing up. Her mind flashed back to their fond childhood memories together, of him pushing her on the swing, of him teaching her how to ride a bike, of him saving her when she thought she would drown despite being in the shallow end of the pool. He deserved her, she thought. She felt proud, observing the sight before her, feeling her brother’s vulnerable nudity and letting him feel hers. She felt wanted.
James leaned forward, holding eye contact and matching her smile. They kissed… and it was *electric*.
He wrapped his arms around her, enveloping her in love, consuming her completely into their private little world. Nothing had ever felt so precious as his beautiful little sister and the physical pleasure she felt from him. He really adored his sister, and the opportunity to give her the joy of sex was all he wanted. Flowers just weren’t enough. Taking her on a date? Sounded like a nice plan, but still wasn’t enough. James wanted to give his sister Ariana the most beautiful and sacred experience that two loving humans can give to each other. He wanted to give her an orgasm.
He rocked his hips between her legs, and she replied by rolling her hips into his rhythm. You could hear her wetness as he slid through it. Ariana just couldn’t help herself. She would’ve fucked him even if he *wasn’t* her real biological brother. Physically, she was very attracted to her brother’s body, but obviously being such close family, direct family members even, made her much more excited to have unprotected sex with him. In her eyes, he was hot as hell, but also cute enough to take home to mom; Which wasn’t so necessary in their case, considering that they have the same mom. She started having playful visions of their father walking her down the aisle. Imagine that, she chuckled internally.
She moaned with deep carnal satisfaction as she felt his hunger burying inside her. Harder, faster, deeper. Thrusting so powerfully you could hear the patting of their waists against each other. The tip of him slid around her uterus, gliding in and out, filling her all the way up. Ari dug her nails into her brother’s back to subdue her cries of happiness. This continued for minutes upon minutes, bringing them both into pure sexual ecstasy. They locked lips and made love, tasting each other’s tongues, and barely breathing for how their lips clung to one another as if they were scared to let go; Scared to have their sibling believe, even for a second, that they didn’t love them with everything they’ve got. Every sensation they could give, it was theirs. Romance filled the air. Faster and faster, their hearts were beating for one another.
James fucked his sister on that bed. Ariana fucked her brother right back.
At that moment, her breath caught in her throat like she had something important to say. He slowed his thrust to give her pause for whatever that may be, without entirely stopping their rhythm. He was still very much enjoying his sister and the warm sensation of her pussy. She was still very much enjoying feeling her brother’s cock, thankful for his continued yet subdued persistence.
“You know, James… There are two types of siblings in this world. Those who have romantic sex with each other, and siblings who have erotic sex with each other. You’ve been fucking me like a romantic boyfriend this whole time” she giggled, playfully faking a yawn “Now I want you to really *fuck me* like a *brother*.”
In other words, less jeans, more genes. She glanced over at the cabinet. It was all the confirmation he needed. Sliding himself out of her vagina (with a little suction as her lips gripped his shaft, and a satisfying flop as his head emerged from her hips), he strode over to the cabinet to indulge in all its sexual treats. Lifting the fresh bottles above his shoulders, he turned to see the wicked grin of excitement in his nude little sister’s face. She threw her hands up with a cry.
“Yay! If you can’t get me pregnant we’ll have to come back and have sex again!”
“That’s the plan, sis” he smiled lovingly “That’s the plan”
And so they drank and they laughed; Telling rude jokes and rolling around drunkenly with each other as the effects of the alcohol seeped in. There was so much passionate kissing you’d almost think they didn’t share the same mom and dad. She wore a collar for him, crawling around the floor naked like a sexy little kitten, purring up against his leg and giving her naked big brother the second sloppy blowjob of the day in return for affectionate head pats and hair strokes. She presented her pretty little bum to him at the edge of the bed, which he soon turned pink with the paddle and his own hand. He even locked Ari to the bed posts with handcuffs and fucked her tight little pussy a second time as she pretended to want to escape; like her elder brother had snuck into her room unexpected and defiled her, taken her innocence, used his little sister’s body as a masturbation doll. She would shake and pout as if she weren’t loving every single second of it.
“Get off me! You can’t do this!” she would wail “What if our mum and dad find out? Get out of my pussy, big brother!”
“Does that mean you don’t like it? I don’t feel good inside you, sis?” he would tease in return.
“You’re making me feel really really fucking good, but this is real incest! It’s very very naughty, James! Just because you’re sexy doesn’t mean I shouldn’t cum all over your cock, even if I want to!”
It wasn’t her most convincing dubiously-consensual roleplay, but it was hard to not consent when you’re so attracted to your captor. In her defense, she’d always heard the other girls talking about you back in your high school days. Even her own circle of girl-friends would tease her about having a handsome brother.
‘I *know!*’ you wished you could reply ‘I’d probably fuck him if he weren’t my big brother’
Ironically, once they’d developed into adults, sane and sound of mind, she realised how silly the barrier between family and sex was. A loving father’s penis will fit inside his excited little daughter’s vagina in just the same way as any less-closely-related couple. A mother can let her son re-enter the very womb he came from. There’s nothing stopping cousins from gagging on each other’s cocks, coming all over each other, and licking each other clean. It was only then that Ariana realised she wanted to have sex with James *because* he was her brother, not *in spite* of it… and also because he was, to be fair, not bad to look at.
As James pumped Ari over and over, alternating hard and soft strokes to prolong their pleasure, she had a brilliant idea.
“The chocolates!” she cheered “There’s one I’ve really been wanting to try!”
James unsheathed himself from her with a wet flop, as she stood to lift the box from within the cupboard. Lifting the lid, there was just one that caught her eye. She presented him with a coffee truffle atop a cream-coloured base.
“Let’s play truth or dare, bro” she winked.

Suddenly there were 10 minutes remaining.
Ten minutes remained, and yet they still had not passed the requirement for success. Don’t get them wrong, they’d enjoyed plenty of incestuous sex with each other already, both oral and vaginal incest. However, the requirement was always to attempt to impregnate a family member. James had to fertilise Ariana.
The siblings looked up at the large digital clocks scattered centrally on the walls around them. It was time.
“Fuck me one last time, James. Make me your slut. Make me your wife. Whatever you do to me, just *don’t pull out*” she beamed, biting her lip in excitement.

[OOC: Hey everyone!
I feel like Chapter 5 brings this to a satisfying conclusion, even though it does have gaps and probably would benefit from proof-reading. This also is not a request for collaboration! I very nearly didn’t post this because I didn’t want to post something incomplete, and I felt like the mods would misinterpret my gaps as an invitation for collaboration, *but* as this has sat on my computer for a month I guess incomplete is better than nothing! Of course, I can’t stop you filling in the gaps and sending me your completed version, which I might post if it fits nicely, but that’s not my intention.
Thanks for all the love on this! It’s been a good time.]
