This is a template involving a female character giving a kiss to a male while both of them have the vacuum fellatio mouth. The LORA has been trained by the artist Hasmk2 with his approach to this concept. I do not see this specific fetish niche done a lot, but I like how Hasmk2 does it, so I made a LORA out of it. You can customize the LORA a bit too with some poses that isn't within the trained images which is nice. I'll provide some image examples if I generate any good showcases of that. 0.8 also seems to be a good weight for this LORA. Use the square portrait for Pony for best results. Human and humanoid characters will work best with this LORA, but furry and anthro characters will work too if you use your prompts and LORA weights right.

Positive Prompts: VKMK2, 1boy, 1girl, duo focus, kissing, deep kissing, anteater face, :>=, female on top, big breasts, dark-skinned male, bald man, eyeless male, hand holding, looking at viewer, blushing, steam, grey background

Extras: nose hook, heart-shaped pupils, wide eyes, bikini

If the bikini still generates even if you didn't ask for it, then just put "naked female" in the positive prompts and it'll remove it.
