変なお姉さん - Hen na Onee-san (Strange Older Girl/Sister) (Patreon)

I purchased the DAZ add-on Squishy Human and it turned out to be a bit different than I expected but still worth it. It's a Genesis 8 or 8.1 figure with separate simulation settings for flesh, bone, breasts, and buttocks. Somehow I ended up making a photorealistic, 10-year timeskipped Senko for the test character. The belly collides with the lap nicely, time to explore the possibilities!

[Added screencap] The possibilities have limits, lol!
