Pretty easy to apply, low chance to fail, commendable hole accuracy and the most important, minimal style bleed. Recommended weight is around 0.7~0.8, weaker on 2D, stronger on realistic (if your realistic checkpoint is struggling to make it futa, just apply my futa erection lora together).

For cowgirl: pov, futa on top, penis, testicles

For missionary: pov, futa missionary, penis, testicles

Helpers: "man's lower body" for the legs and "from above/from below" to adjust POV

Despite the name, it also contains regular cowgirl/missionary data, so should be pretty easy to gen hetero anal if you want to, even 2 males if you will, but don't expect it to be refine, this is not the scope here.
