guys, is being autistic the ultimate way to get girls to fart on you?

>visiting family with my sister
>cousin is fat and heavily autistic
>in previous years whilst helping auntie with his computer, i've seen sfm fart videos on his youtube history
>sleeping at their house for the weekend
>aunt and uncle go to bed
>me, my sister and cousin on couch watching movie
>cousin "stimming" out, kinda annoying me
>sister has always been patient with cousin and probably given him way too much leeway over the years
>sister shifts slightly and lets a poot out into the couch
>cousin instantly stops acting out, gets animalistic look in his eye
>"anon's sister did you just toot?" slobbers out
>sisters giggles and excuses herself, doesn't realise how captivated he is
>notice him sorta sniffing the air
>he's wearing baggy pyjama pants and has an obvious raging boner
>says something autistic like "ew we should call you farty bum" or something like that, acting like he's teasing her but really i can tell he's just fantasising
>10 or so mins go by
>hear my sisters stomach bubble
>"hey cousin"
>she shifts over to like point her ass at him, but basically ends up just putting her ass right by his lap
>rips 3second bubbly fart, even turns me on a bit
>cousin is laughing like an autist but pretty sure he just creamed his pants
>sister literally just thinks he's being "himself"
>next morning whilst cousin is out with auntie, decide to check his PC again out of curiosity
>discord open when i unlock it
>he's DMing with some other autist from his spec-ed group about how his "hot cousin was farting on his lap"

Kinda wish I was lying about this lol, got more
