Lori breastfeeds Lisa

>Lisa is having trouble falling asleep
>she does her experiments until late at night and can't relax afterwards
>she sees how Lily always sleeps very well after being breastfed by mom
>she knows she can't ask mom, but her calculations indicate that Lori would be able to produce milk if properly stimulated
>Lisa begrudgingly asks Lori for help, making it clear is a physical necessity
>Lori is weirded out, but as her small sister starts crying she remembers she's only 4 years old and not an adult as she often seems to be
>she reluctantly accepts, much for Lisa's entusiasm, and follows the little genius to her room
>the oldest Loud awkwardly sits on Lisa's bed
>Lori still feels uncomfortable as she removes her top while Lisa gets on her tiny pajamas
>the 4 year old gets on Lori's lap
>"thanksh for doing thish for me Lori! I... I love you"
>Lori gets emotional, as she doesn't remember the last time Lisa was so affectionate to her...of to anyone
>she removes her bra and lets her firm, plump breasts out
>Lisa's eyes shine with anticipation and she slowly grabs Lori's left tit
>Lori feels weird at first, but Lisa massages her breast (just like she saw on the internet would be the most effective way to stimulate milk production)
>Lisa's small mouth can barely cover Lori's pink areolas
>Lori starts feeling a tingling sensation coming from within as Lisa's suckilng and massaging intensify
>she realizes it actually feels pretty good
>much to her suprise, a small pressure starts coming up in her breast
>the strange sensation of milk coming up the ducts hurts a little bit, but suddenly things change as the liquid comes out
>Lisa, although expecting her calculations to be correct, ends up getting Lori's milk all over her small chin and dripping in her pajamas
>she's really happy it worked
>Lori is glad too as she sees her little sister smile
>Lisa realizes her top is wet and quickly removes it before resuming sucking on her sister's tit
>strangely, Lori doesn't feel weird anymore

>the milk coming out is a strange, new sensation
>somehow Lisa sucking it feels good
>even better than when Bobby does it
>Lori doesn't understand where that thought came from
>she remembers how sensitive she gets when Bobby sucks on her tits
>but to actually have milk come out feels so much better...
>she embarrassingly looks down at her sister, shaking off those thoughts
>Lisa has her eyes closed, trying to relax as she drinks the warm milk coming out of Lori
>sometimes Lisa sucks a bit too hard and hurts Lori a little bit
>but even that is sort of...good
>Lori can't understand why but she starts feeling hot
>sweat starts coming running down her neck
>just as she was going to stop Lisa, she notices her little sister is asleep
>carefully, Lori puts her down in the bed
>as she covers Lisa with a blanket, Lori feels strangely proud of having endured this weird experience
>she always loves to help her smaller siblings
>Lori picks her clothes up and doesn't even bother putting them back on, as everybody is sleeping by now
>she quietly gets out of Lisa's room and heads back to her own
>in the hallway, she looks down and realizes milk is still dripping from her left tit
>the right one feels kind of full...perhaps Lisa should have alternated
>as Lori is pondering about the whole event, reaching for her door, she turns her head towards the end of the hallway
>there she sees a dumbfounded Lincoln in his underwear staring at her with his jaw dropped
