Lisa Ex Machina: (Failure) Turn to the Left and keep going 'till you find the end of the Family Tumbleweed!

The screen flickered with the image, one Leni Loud- which was entirely to be expected given that said image had come from the phone of their mother, courtesy of one of many recording devices implanted within it for assorted reasons. What was not to be expected was the clear visage of her bare breasts above the falling sheets that covered the rest of her body, nor the similarly bare form of their brother beside her with panic twisting his features.

There were only few frames of it, not even enough to show movement but it confirmed the suspicion that Lisa had had ever since her sharp eyes caught the briefest flash of an image before the camera 'broke' on the other end. It didn't take her of calibre of genius to make the connection that someone was trying to hide something, and now with the freshly retrieved image upon her laboratory screen she knew exactly why.

After all these years, the inevitable conclusion of Leni's deviancy had come to pass. Perhaps once it had not actually been a certain thing, but the necessity of a carer thanks to Leni's own nature and Lincoln's tendency to fill whatever role was needed of him by the family had certainly done away with any doubt.

"A deviant contained with her very target of affections for weeks at a time, with not even a single other person to behave herself around." Lisa shook her head. "You were well aware of her condition… truly maternal unit, you have only yourself to blame."

Of course, Rita Loud had been in little position to offer better, the older sisters had already long departed to their own lives and responsibilities and expecting them to give them up to care for Leni and her career would be unfair at best. The younger children could hardly have cared for their older sister- if for no other reason than they were unready themselves for a such a responsibility.

Obviously excepting Lisa herself, but Rita would likely point to the genius's habit of live experimentation on her siblings as a red flag for any such thing.

Lincoln was the only clear option left, as someone who was familiar with Leni's 'quirks' and had proven capable of teaching her at her most 'Leni' he was likely the very best option if not for another 'quirk' of Leni's that he was unaware of. In the end, Rita likely had to face the hard fact that Leni simply could not both pursue her career and the moving out it required, and also not have Lincoln care for her because they just didn't have the finances Lynn Sr had provided for a paid professional. Then, unwilling to extinguish her ditzy daughter's probable once in a lifetime chance, she chose to roll the dice on Leni's medication and Lincoln's restraint.

"Maternal unit… mother.

You were a fool."

Lisa clicked off the image, sparing her retinas any further imagery of sibling love. "Did you really miss the entirety of our lives under the same roof? Lincoln's resolve against a sister's wishes has never lasted a week nevermind the months they have lived together in some capacity."

How long had it been since their first coupling? Had it happened when they went to New York, or had Lincoln cracked before then?

Was it the very night Lincoln first stayed over?

No, Leni's capacity to lie was limited at best; she would have 'spilled the beans' or at least raised red flags with Dr Greenberg. This had to have been a recent development.

Either way; it was time.

Lisa quickly clicked through menus, reaching deep into her assorted projects. Many were closed, but far, far to the back one stood out as being marked active despite its age.

With measured trepidation, Lisa Loud re-opened Project Absolution for the first time in a decade.

Her memory was near perfect, but she needed to be sure no details had been forgotten in a matter of such importance and thus she opened up the first, and so far only video log she had made in the Project.

Instantly Lisa found herself face to face with herself and she was briefly swept by uncharacteristic sentiment upon seeing her younger counterpart still within the shared room of their childhood. In the background a once ever present bustle of life was pierced by forgotten strings of Rock Music and the barks of a living Charles.

For just a second, Lisa closed her eyes and imagined she was still there.

"Universal Date-" the dream was pierced by the younger Lisa's precise timekeeping. "- A possibility I until recently considered absurdly unlikely has come to my attention as being… more probable than I would have ever imagined;

If I am not mistaken several members of the my familial unit have developed a dependency upon my sole brother unit, possibly to the point of nascent romantic 'inclinations'. The various potential causes of said inclinations are innumerable and largely speculatory.

My most solid hypothesis being that Lincoln's tendency of conforming to whatever role is required to fulfill a sister's needs has contributed to their developing pubescent states confusing their familial affection for less platonic desires. Perhaps subconsciously contributing to the perception that he would effectively fulfill their 'other' needs as well."

The younger Lisa's distaste ran through her voice despite her stoic expression. The elder simply sighed at the irony.

"But regardless of the cause, the reality is that no such coupling could end in anything but tragedy. The most effective method of avoiding such would be to simply engage in some mind alterations to remove the patterns in question. However my own expertise in such delicate procedures remains… untested as yet.

Therefore I have resorted to a simpler solution; the first stage will be to provide a genetic cleanser of sort across the entire familial unit to prevent any defects in a potential infant borne from an 'indulgence'. This would obviously not prevent the other likely trauma and distress brought about such a coupling once discovery occurred, but would serve as damage mitigation.

I shall reveal this cleanser during my fifth birthday party, as I will likely be queried about experimentation upon my siblings in the future and have a poor 'poker face' that may lead to discovery. At least through this reveal it may be assumed to be simply be a 'passion project' rather than a response to a distressing deviancy within the familial unit."

The current Lisa mentally rewound to the image of Leni as she had appeared on the call, she bore clear signs of a 'rough' coupling that had been conducted in passion. In all likelihood neither had planned it, so unless Lincoln could convince his partner to take a Plan B pill, Lisa's contingency would be soon tested.

"Of course, further distribution of the cleanser should be considered otherwise it would appear obvious in hindsight that I planned in case of this scenario as no other benefits are provided by the treatment and therefore the only possible use for it would be for conducting 'Line Breeding'. If I am not careful, it could even be reasonably assumed that I may have had part in causing such deviancy as I clearly knew of it beforehand and have taken a less than… consensual approach with experimentation on my familial units in the past.

The second stage should amount mere observation of these tendencies as they develop and hopefully decline. But if any one or more sister units should show continuous and growing deviancy I will attempt to first find partners that fit their desired profile and either directly or indirectly direct them to fulfill their desires with them.

Failing that I will attempt what treatments I have available to me at the time to curtail these deviancies..."

Lisa snorted, allowing herself a bitter laugh.

"…. compile a list of the most capable therapists our full finances have access to and attempt to address it-"

She closed the video.

It was ironic. Her efforts had failed, certainly Leni was the only one so far to have 'fallen' but it was but a matter of time. The older sisters seemed to have satisfied themselves for now, but they had done so without her intervention- she could hardly claim credit for their success.

The younger sisters were another matter.

Not even excepting herself.

She started a new log.

"… I have failed.

The second stage was only partially successful with Leni Loud for a relatively short period of time, but following our Da-Fath- Paternal Unit's death the trauma and desire to reaffirm her connections has seemingly intensified Leni's pre-existing condition to the point of full manifestation and a seduction of our brother unit.

Lola, Lana and Lily Loud all present signs of abnormal devotion and desire in their behavioural patterns similar to those presented by sister units I have previously diagnosed. Lucy did so prior to attaining majority, and I can only assume continues to do in her new residence.

None of my behavioural therapies or social programs have retained their effectiveness over a long timescale. Hormonal repressors cannot be attempted given the delicate state of puberty, and Leni has demonstrated that the condition would only be partially repressed through treatment in adulthood by either myself or Doctor Greenberg.

Most embarrassingly of all-"

Lisa closed her eyes for a moment, then opened them and regarded herself properly;

Still short, but soon to be tall for her age. Her hips were widening and her chest bore voluminous breasts that been expanded well beyond any efficient size, or sense of her own vanity.

The treatments were doing well. A pity it took until now for to realise her own lies about the motivation behind them.

"It now seems obvious that…"

"… I am…"

"..."

"I don't know what to do."


A/N:

Another one that was meant to be funny, with Lisa having planned for a Loudcest future since the only use of her 'cleanser' would be if the Louds had children with one another as Lisa didn't mention using it on anyone else- so it so far seems to be only logical motivation for her to make it.

Obviously it turned out differently.

Regardless, unless the good Doctor makes another fic this should be the last one for a while, though I do have another potential one in mind for the future.

Next time we'll be back to the funny content :)
