Can anyone help me find or recommend me a 3ba preset that actuallly gives females a big body

[Not Plague]

i see a lot of ( in heavy quotation marks ) thick bodyslide presets going around where they just make the body a lil bit bigger and nothing more but i want an actually big girl something like the images attached ( unfortunately these in the pictures are only for CosioHD and that's LE

 

i'd also be pretty grateful if anyone could show me some good animations for posing

You should be able to get this effect with 3BA by playing around with the sliders in bodyslide.

As someone who made a thicc body in the past, I will warn you that sexlab animations aren't made with that type of body in mind and will experience rampant clipping. Your partner's hands will forever be disappearing inside you.

 

If you still want it, just crank up the part sizes and body fat sliders to get a good start. Making a custom body isn't hard once you put your mind to it.

'Ceres Deluge BodySlide Preset for 3BA BHUNP CBBE COCO 3BBB' on Nexus is one I recommend. If you want to crank up the thiccness you can just use this preset as a starting point and tweak the sliders as others have mentioned.

Seconding S4RM's stuff, at least as a starting point
