suggest weight: 0.5~0.6

as far as I tried, this Lora is stable enough(8 out of 10, out comes what you want)

basic prompt: 1girl,1boy,hetero,standing,sex from behind

add your own chosen prompt, such as: "breast grab","arm grab","shoulder grab","ass grab","torso grab","grabbing from behind","looking back","bent over" etc

It has different viewing angle, for now, "from side","facing viewer","from below","from above"are available....I did train from behind version, seemed not working.
