Three weeks have passed and Juliette makes her move

She was feeling... pent up. She had infested James's dick, and spread herself that the parasite within would obey her directives and eventually merge with her to become one, once the time came. But until then it obeyed her, it enlarged, fertilized and hormonally boosted James's dick. There was now no way that the Juliette would reject intercourse with James. However She was not foolish, even if James's dick was inferior with all the improvements she had been making increasing the volume and size, she needed to eat away at his own seeds fertility otherwise any female he lay with would be too busy with pregnancy rather than gestating proper spawn for her.

She had also started working to prepare James, both that James mind and body would accept the changes she planned for him. But She also started to train James to accept the sexualization of his dreams and being, the sexualization of his entire world. As he slept she would encourage his mind to focus on the women She saw around him through his eyes, all while ensuring that his body was at the peak of its physical need for breeding.

James was aware though of her influence now, he knew something was wrong with him, and he knew whatever it was was keeping him away from a medical inspection. In a twist he tried to think of ways around her influence and inadvertently gave her a wonderful gift. James possessed a secret cooler where he stored a number of illicit beers he hid from his family at least until he could openly possess the drinks, and so he purchased a thermos and planned to fill it with material to give over to be tested by medical staff. She encouraged this filling the thermos with his sperm and at least eleven Eggs hidden inside. James would eventually consume the thermos and so thoroughly infest himself that she could drive them closer to a complete merging.

Then the cooler, the beers, and the thermos all disappeared. She had been enraged, and until punishment was promised by the Alice did she finally relent, no longer bringing James to pain if he abandoned the search for her eggs. Instead she lay relatively dormant, relenting and focusing on preparing James to become the ideal version She had in mind.

***

You woke up and started making breakfast. You might not be as good as your mother and particularly your father. But eventually you get a pile of chocolate pancakes prepared and waiting as your parents left their room. It was a little late, but they were about to celebrate their twentieth anniversary. Your Mother had saved up leave time, and had even leveraged for extra time off using the argumentation of remote working effectively earning her and your father an entire month to take cruises across Europe. You Father meanwhile had more than enough good favor with the neighbors, and both your sister and yourself were burdened with the task of caring for the farm with the only real good news being that there wasn't much work to do.

Your parents eventually both left their room glowing with what you could only assume was a post sex glow and clearly ready for their trip. This didn't stop either of them from gawking over the pancakes you made.

"Oh sweety these are amazing. But if you want to get us a daughter-in-law..." Your mother began before getting cut off by your father.

"Or at least give me a grand baby before I die." Your mother gave one of her playful frowns before continuing.

"You might want to advance beyond making the best breakfast foods in the county. Breakfast tells her you're a keeper, but Lunches or Dinners are what get her attention." This caused your father to break out laughing.

"Quickest way to a woman is always going to be her stomach." Your dad began with a lewd eyebrow waggle. "I actually broke into the local Highschool, bringing some of my own supplies and cooked a whole special course meal just to show your mother how serious I was when I promised her that with me she'd always eat the finest meals."

Your old man smiled some. "She insisted I give her a whole other meal after that." As your father said this a pancake slapped him in the face as your mother laughed at her throw prompting you to join the laughter.

"Dear I don't think..."

"Morning Mom, Morning Dad!" Chipper and happy Juliette barged into the kitchen, and immediately your mother frowned. It's been nearly a month since, your incident with Juliette and somehow she's severely degraded since then.

At first she was dressing oddly at home, and then there were calls from school where she was physically assaulting the boys at her Highschool. At home she tended well to strip, first it was just her shirt, but now as she walked into the kitchen, now was her worst offense, entirely naked. (No look at it, She knows she's showing off the wonderful breed-able form she has, that She wants you to share). As you and your father carefully avoid looking as your sister casually walked in the buff to the fridge, you considered that second kiss the two of you shared. And you considered your sister's strange avoidance of you, even her friends called you last week after noticing a odd change where she had gotten...aggressive with them, sharing a full blown make out session with her friend Ashley, and getting handsy with the rest.

"Juliette what do you...?" Your mother was about to lecture your sister before she slammed a drink down on the table with two straws.

"Happy anniversary. I came running out from bed to make sure you guys didn't miss my special treat I made for you both last night." Juliette stated very loudly and deliberately before suddenly her demeanor changed slightly. It was like a switch of realization went off in her head even as your mother trembled in outrage. "I-I didn't wear anything to bed last night...And i just ran out here butt naked to...oh...Umm enjoy the smoothy and I'll be back." Your sister blushed heavily running out the room, though with a look at her thighs you suspected there'd be some liquids for you to clean off the floors later. (She wants you to leave it and claim Juliette. She thinks she deserves to lick it up.)

Which left your family with your sister's other dramatic change. Though compared to everything else this was the least weird. Your sister had been obsessed with smoothies, health drinks, and tended to experiment with them, that had been her thing for months on end. But recently she was laser focused on, in her own words, "making a protein shake that tastes so good that even fat losers will actually go to the Gym for one".

With a shrug your father takes a sip before pulling back in with a disgusted look. Alexander Amon had a very particular palate, and things like protein shakes or anything he deemed too 'unnatural' usually gained such a reaction from him, he even avoided most cereals and a wide array of chips and soft drinks. Your mother on the other hand, while having developed tastes after years of your father's cooking, was still far more open to trying any food.

"Well your sister still has a long way to go, this tastes well still pasty. As for her look..." Your mother handed the empty drink cup to you while both your parents slowly moved towards the door. She was clearly about to begin a tirade but your father cut her off.

"Its biology, She's a woman and the instinct has hit her HARD...she's probably going to be the first to carry any of my grand children. James keep her in check while we're gone."

Your mother gave your father a frown. "Oh she's just a woman? Is that it?"

Your father gave a wide grin at that. "No, she's taken after her mother with my family's tendency for extremes that's it. Like mother like daughter, I wonder who the man is?" Your mom kicked your dad in the butt earning his yelp. Immediately your father bolted out the door with your mother giggling like a schoolgirl in hot pursuit.

The pair chased around the property until your father dived into the car, your mother immediately on top of him. The pair play fought in the seat for several moments until their lips locked. You could swear your mom was grinding on you dad for a couple seconds before the pair property buckled and the car took off. (She can't wait to join in with them as well)

Then your parents were gone and you were left incharge of the house. You considered your options for several moments and finally decided to confront Juliette. You approached her room and knocked on her door. "Juliette, Juliette listen we need to talk and maybe set some rules or something... Juliette, come on Juliette...are you in there?" After minutes of knocking and no answer, you gave up the absolute silence from her room making you feel she might be in there.

You then decided to go back to clean the kitchen when you heard the sound of the shower. You must have just missed her going into it. You knock on the bathroom door. "Hey Juliette listen you and I need to talk so when you're done in the..."

You were hit, the blow to the back of your head nearly blacked out your vision and everything was fuzzy as you hit the ground. But with a twist you could see her, she was still entirely nude and drooling from both mouths. Juliette was standing there with a soft faced mallet in her hand, one that had a slight amount of your blood on it, and a entirely panicked and shocked expression on her face.

"No! You're supposed to be ****!" She screams in a panic.

"Well I'm not!" You scream back, a hand on the throbbing impact site as you quickly scoot away from your insane sister.

"No, no no no! Stay still!" Juliette then shouts taking bold steps forward. (How dare she attack James! She sees now you must dominate! Pin her take her now!)

You leap up to try and catch Juliette with a surprise tackle but she stumbles and dodged instead dropping the mallet and grabbing your belt yanking your pants down and, as you both struggle, entirely off your body.

You flip around so your facing her while still on the ground, and realize your dick is out...and that Juliette is staring at it entirely enamored. You're about to move again but Juliette moves first and suddenly her head slams into your groin painfully, but that pain in soon followed by the feeling of Juliette's tongue running along the length of your dick.

You freeze in absolute confused shock. (She didn't expect this...take her and breed sense into her!) Your cock hardens slowly as your sister moves to ensure her licks and kisses can match the entire length all the while you could hear her moaning, "Oh fuck yes", to herself. Slowly under your sister's care and despite the pain you reach a full mast of eight and a half inches, nearly twice the size it was before the start of the month.

Once your dick is at its full size, Juliette seems to marvel for a moment. "Its fucking perfect." You hear her whisper before you next hear her gag and even **** slightly as you also feel your dick go into her mouth and then into her throat. Your frozen for several moments first in shock, then enjoying the feeling. Your sister was suffocating herself on your dick, her head not just bobbing but thrusting itself back and forth with a slight twist of her head each time she pulled back as her lips and tongue played with your hard dick.

Juliette then broke away slightly her hand firmly grasping and pumping your dick as she rapidly licked your cock head and around the glans. "Oh fucking Gawd I've been dreaming about this for so fucking long! Hehehe... You have no idea how long I've wanted this. The therapist we have at school, she thinks I got over this, I'm sure mom suspects something. But I've been wanting to **** myself on your dick for so God damn LONG! And when you kissed me, I couldn't stop cumming you glorious bastard! I had to throw those panties away you WREAKED them so badly!" You sister threw her head back onto your dick gaging more until she drew out your first orgasm which she took in her throat. She trembled and you could actually hear her squirt hitting the hard floor behind her.

With a pop your sister pulled off you and sat up. You could see her churning your cum about in her mouth, a fierce blush on her face and a near creepy look of ecstacy consuming her expression. "Its...its not what I imagined but it's you and it's amazing!" (She is confused, did the dick size change really have this much impact?)

"Ok, my man" Juliette began as she crawled up you. "Time to destroy my fucking guts!" And then she lowered herself slowly into your dick all while biting her lip. Your dick slipped and Juliette raised herself and tried again only for you to feel her puckered ass and for her to squeak and raise up again.

"H-having trouble you crazy bitch?" You ask, a little more confident, but snapping quiet as your sister growled pulling up the mallet from the floor before setting it aside grabbing your member then slamming herself down on it. You groan as you suddenly find yourself all the way inside your sister, the tightness of her cunt driving your hips wild as your hips strain and thrust upwards against her weight.

For her part Juliette freezes, eyes wide and unfocused, small incoherent gasps leaving her as she stared sightlessly into the ceiling. Your hips continue to try and thrust in response to the sensation even as your mind struggles to process the feeling engulfing you. As your dick starts to move however you can start to see the blood where the two of you are connected. Juliette then starts moving again, however she moves like a puppet or one possessed her hips trying to thrust against your man meat while her mind is clearly lost.

After several moments of this you feel yourself cumming, burst after burst releasing into your sister's once virgin womb. This seems to pull Juliette from her stupor as she then still out of it looks down at you, then seems to register the cum spraying into her body. "OH...OH GAWD yes!" You can feel her tremble atop you and then Juliette collapses catching herself on your chest. "How. How the hell are you still hard?"

"Juliette, please, what are you doing?" You demand but your sister just giggles and starts moving her hips again, sliding herself now back and forth and taking moments to rotate her hips in a circle with your dick until you start spraying again.

As your cum shoots up into her dick Juliette smiles. "Getting what I've always dreamed of you glorious, perfect man....oh god there's more...I can't even contain any more, oh fuck yeah your perfect!" (She knows it, glad you finally appreciate it stupid sister.)

You try to sit up, but Juliette pulls out the mallet threatening you. She then stands up and you can see your cum dripping out of her blood soaked snatch. "No, no no, stay in there babies, stay with momma." Juliette moans using her hands to try and keep your cum in her cunt. She then drops between your legs where your still hard dick is.

Juliette then kisses your dick lovingly before licking your cum off of it. "This thing was made for me, and my cunt was made just to fuck this dick." Juliette said it almost like a mantra before setting in and licking and sucking your dick while beating off whatever parts where not in her mouth until you came again, and once again filled her mouth entirely. Again Juliette seemed to tremble as she swirled your jizz in her mouth before swallowing. And now as you felt like you'd die of dehydration your dick finally started to go down, though Juliette's licking seemed intent on bringing life back to your dick until finally with a moan of disappointment your sister gave up.

You sat there with Juliette stranding your crotch for what felt like a eternity as your own cum slowly dripped out of her and onto your flaccid dick. She seemed enthralled and eventually she even began to thrust her own fingers into her mouth moaning in renewed ecstacy. "I've never felt this good before, this is amazing!"

Juliette then threw her face into yours her lips connecting and the two of you began to kiss frantically. Soon both tongues again began to rub against and wrestle with on another. As you kiss suddenly you hear it. "Oh gawd brother I've been masturbating to dreams of this for years!" [That's right Slut, and Slut will make you a even better Slut for precious Onii-chan as your cartoons say]

"Wait what did she say?" (She's confused what's an Onii-chan, and why is James thinking...like...wut?)

"Huh, I didn't say anything. Why would i say shit when i can suck this glorious face?" [Slut doesn't want you to stop, keep sucking...wait.]

Your eyes snap open as you and Juliette keep kissing you and your sister both breath in before intensifying the kiss as you think. "There's no way this is possible." (She doesn't fucking believe it.)

Eyes closed Juliette almost painfully pressess into the kiss more. "Will he just shut up and keep kissing me? If he's not going to beat and **** me he owes me this much, this feels too fucking good to stop to have some stupid chat." [Slut is so glad you're dumb whenever this fucktoy is around.] (She demands to know who the fuck are you!)
