    [flux2-klein-9b] Pyro's BJ

    New Model, New Pyro

    This is an experimental Lora

    Research: How few ranks can you get away with?

    Result: 90MB lora that understands more about anatomy than your biology teacher in 5th grade.

    Also, it's literally the most trainable model I've ever trained with. It's so good I'm going to train it with 100k z-image-turbo images to make my own z-image-base because Alibooba is seemingly toying with our emotions. (If you want to sponsor this project shoot me a msg on discord)

    How to use?

    You can use this model with BASE and DISTILL. You can also edit images with it amazingly well.

    Use BASE for better prompt adherence

    Use DISTILL for images faster than you can jerk off

    Pls try my distill workflow attached as TrainingData zip-File before telling me or the world that the distill doesn't work well. Thx.

    Demo Images should contain workflow

    In theory the LORA understands following concepts (in practice it's a bit shaky but that's why it's experimental, you'll figure it out):

    General: a woman sucking a penis

    Chipmunking or whatever this shit is called: a woman cheeking a penis

    Deepthroat: a woman swallowing a penis

    What could this be: a woman licking a penis

    If you want her to look at you in disgust: pov

    Will experiment further until I uncovered the mysteries of flux2-klein-9b and prompt adherence is at a point where you trust the LORA more than your mom.

    10/10 description format. Will download later and try.

    Are you training locally (what hardware) or renting?

    Works well in edit mode, but text-to-image using the LoRA doesn’t work out of the box (it’s even worse when adding a character LoRA). I’ve only tested it with the distilled model so far; I’ll do more testing with the base model.

    all images in the album are made with the distill so I can't confirm that it doesn't work well with the distill... pls try the workflow from those images and report back

    I attached my workflow as zip if that makes it easier

    DrakeniJan 21, 2026

    What are you talking about? The LORA works flawlessly with t2I and I2I. You are doing something wrong. I get good gens 95% of the time.

    mattinglyjohn722Jan 21, 2026

    I am getting very good results with both T2I and edit. Tried with two different Character lora and still getting very good results.

    In case you hadn’t noticed, it greatly improves the quality of skin textures. Using the same system (I don’t know whether you used image pairs or just individual images for each concept), you could create a LoRA to improve skin realism.

    Can you please tell how you gather dataset and what typical pair of images look like (or upload a few)? I want to understand how to keep good resemblance, quality. and flexibility when training lora.

    Can't wait to try this lora since the others I've tried for F2K9B have been surprisingly great. This model has so much potential. Thanks for sharing.

    can't get deepthroat/swallowing to work but other than that it does work.

    DrakeniJan 23, 2026· 1 reaction

    Prompt a small, short, thick penis. It will look like deepthroat. I've also had some success telling it to have the subject sucking/kissing the crotch, and leaving a description of the penis out.

    How to make woman's face to stay the same with image workflow? I have a problem that her appearance is quite different from provided image.

    Light6969Jan 22, 2026

    Yeah same, although still a good lora, depending on your goals.

    ZootAllures9111Jan 22, 2026

    This guy openly admits to not captioning his datasets correctly on Reddit lol. That's almost certainly the cause of that issue.

    crombobularJan 22, 2026

    @ZootAllures9111 wait seriously?

    Lora_AddictJan 22, 2026

    @ZootAllures9111 couldn't find him saying that on Reddit. Even if, you doing something wrong bc this works pretty good most of the time.

    jonog247634Jan 22, 2026

    If you use the NSFW and head_swap loras it works great also the anatomy slider can help if needed!

    ZootAllures9111Jan 24, 2026· 1 reaction

    @Lora_Addict He made a post both when the original Flux came out and recently after Klein came out basically insisting that captioning very little is the "right" thing to do. Which is precisely what causes the sort of issue @guy33 was describing, on every single model architecture ever released. Anything that isn't explicitly captioned WILL randomly show up in generations and / or be impossible to change / remove in a way you can't control by any means beyond the actual lora inference strength level in ComfyUI or wherever.

    Lora_AddictJan 24, 2026

    @ZootAllures9111 yeah possible, the Lora still works amazingly good :D

    I'm going to treat you all to something nice. Take a POV photo of your own cock, looking down at it.

    Use this image as the only reference image with this LORA. Ask it to edit in a person sucking your cock, describe the person. Ask it not to change your penis.

    Viola! Custom fantasy blowjobs.

    erdelman73267Jan 25, 2026

    it does not work, I tried to use Dredd's dick, it will always add dick that LoRa has been trained with, u have to use two images edit mode and then it will replace it but it will not look good as it just does copy paste over from one image to another - it does not know to make it seamless and match colors and textures, it treats penis the same way it would treat shoes, bags, watches...

    @erdelman73267 0.6 strength is your friend and proper prompting

    DrakeniJan 30, 2026· 2 reactions

    @erdelman73267  It does work and the prompting is simple. I turned around in my computer chair, snapped a picture, popped it into the image node in comfy. Then I prompted "A woman is kneeling, sucking my penis. POV Blowjob."

    95% success rate.

    hirez80462Feb 25, 2026

    @Drakeni and how to do the reverse? taken a picture of a woman and want to add a penis from a man, could be either pov or just Add it close to her face, or any other part. Extremely greatful for any directions, not found much that worked for me.

    I'm not up2date about civitai drama, since i basically never visit this site except when uploading shit.

    Why would it get yeeted? Are there policy changes I don't know?

    anonz11Jan 23, 2026

    @pyros_sd_models I hope it doesn't, but a lot of similar Wan 2.2 loras (like the jump cut lora, and @ffjggrtbjibv's genitals lora) have been yeeted these past few months. Basically any lora that can turn an SFW initial image into an NSFW photo/video. But that's why we have Civarchive.

    @anonz11 thanks for the heads up. what's the preferred alternative for hosting loras then? huggingface?

    green_angerJan 24, 2026

    @anonz11 Civarchive? I cannot help but cautiously ask what (and where) is it? Tried searching, got messy different results. And I feel like it may be very helpful in the foreseeable future. A simple hint will do, if full address is not appreciated around here (who knows considering your own bet).

    @pyros_sd_models yes, huggingface is what's mainly being used for mirror links.

    Can this be generalized to any penetration act? I'm having fun making anime to realistic gens and most of the time the result is awful whenever a penis is involved.

    SeoulSeekerJan 30, 2026· 1 reaction

    probably not, this is a blowjob lora

    NOTORIOUS_EDDYFeb 5, 2026

    i added this lora and penis lora and prompted
    "POV of asian girl spreading her legs in front of a erect long penis"
    "POV of asian girl spreading her butt cheeks while looking back at camera in front of a erect long penis"
    "POV of asian girl in front of a erect long penis, she is spreading her butt cheeks while looking back at camera"
    it took few iteration of run ( i always do batch run of 5-10) among them you will always find one which has accurate anatomy no weird shapes.

    reason why i am using 2 different lora for it is because BJ lora works best with POV view.
    penis lora that i got for flux adds very well accuracy in anatomy. keep 0.5 0.5 strength for both.
