am i acting up for nothing

am I overreacting?i’ve been thinking of this a few weeks

was hanging with sister while waiting for something in a lounge im 20 she’s 12.

we were joking around and nagging each other.

at one point i put my hand on her upper leg briefly.

she had no response cuz she was distracted on her phonebut i moved away and started immediately overthinking

is this a crime or big deali didn’t touch her crotch and had no sexual intent

I’ve even remembered my mom, did something similar when explaining something to a doctor, and it wasn’t really a big deal like that.

we we’re literally just hanging out regularly before and after nothing sexual going on but i’ve thought of it over a week now and i keep thinking whst if its innapropiste or a crime and it’s really starting to bother me.

i have a history of having anxietyt over something that isnt truly a big deal but idk if this is a part of that or not, and im stressed out
