This is an amazon position lora focusing on the rear view trained under the 3D video artist AnonBluna. It'll get the position right pretty well, but sometimes the feet might generate a bit bad. You can either have the female lean forward or show their back. If you want them to lean forward, then I suggest putting "mating press" in the positive prompts too so it won't show their head. You can describe the hair type too, but doing so may not make the female character lean forward and instead have their back straight. Lower the weight by .1 - .5 for pose flexibility like having the character look back or wanting it at a dutch angle. Furry characters work fine as well. If you have "mating press" prompted in while the lora is on a lower weight, then there's a medium chance that it'll come out weird and fuse the characters together or it'll add another male into the mix. Finally you can add "leg lock" while lowering the weight a bit and there's a chance that it'll generate that well, but most of the time it has a hard time getting that to work.
