About the Anima Version

I made a mistake, this LoRA is overtrained and worthless. Really you don't need it to get good results. For those that bought it, a refund plus some buzz for your trouble, I'm very sorry. Don't get it.

If you want to create images that do this straight from the prompt, try these prompts:

inverted fellatio, reverse fellatio, 
{blonde,
   {short hair, bangs,|medium hair, twin tails, bangs|long hair, ponytail, side bangs}
|
brunette, {tifa face, huge breasts, reddish brown eyes,low tied hair,|aerith face,small perky breasts, ponytail, aqua eyes, pink hair ribbon,}
|
cat girl, {pink hair, white ears, white ear fluff,petite,|streaked hair, black and brown hair, brown ears, blonde ear fluff,medium breasts,}
}
on back, on bed, head hanging over edge of bed, head upside down, hair hanging down,
{performing fellatio on a man with a thick penis, saliva strings,
{|choker collar|hand on throat|throat bulge},
{|performing fellatio on a man with a large, veiny penis, {|from above,dutch angle,}
{|cum on face, cum on dick}
{|choker collar|hand on throat|throat bulge}
|
mouth open, imminent sex, hands at her sides, no tongue, {|from above, male pov, solo,}}
{|{white|black|fishnet|striped sheer} thighhighs},}
{The background shows a bed with throw pillows,
{|luxury|royal|log cabin|highrise apartment, curtains, city skyline view} bedroom {with a window| night, | early morning light, sunrise}|
The background shows a night club scene with a bed in the middle of a strip club. Blue, pink and red lighting, blurry nude women in the background pole dancing, a pink neon sign reads "VIP Room" in wild stylized lettering}

Or just a plain prompt should kind of look like this:

reverse fellatio, 
1girl, on back, on bed, head hanging over edge of sofa, hair hanging down, thighs together,
performing fellatio on a man with a thick penis,
cum on face, cum on dick, excessive cum,
The background shows ...

No plans on releasing a LoRA for Anima, as the model already understands it pretty well.

About the Illustrious Version

This model is for creating inverted fellatio image generations using the side view. It is not trained on POV inverted fellatio whether the male or the taker POV for that matter.

This model has a strong 3DCG bias. Much of the training data came from generated images from my private LoRA, which was overtrained on 3DCG and one particular catgirl video. Some of these biases have leaked in through using too many stills from that video in this version. Expect a revision of this LoRA in the future.

Also important: This LoRA tends to make a double-decker bed so to avoid this, prompt the floor i.e. tile floor, wooden floor.

Example prompt:
1girl, solo focus, inverted oral, sloppy bj, on bed, on back, long hair, head hanging over edge, head tilted back, fellatio, balls deep, closed eyes, milf,

Prompting 1boy is not required in most cases. If you attempt to use this with realism checkpoints, increase the strength to 1.1 and the CFG to >7.0., and prompt 1boy. But due to the high LoRA strength, expect a freakshow. You may be able with cropping to obtain a useable section of the image (that's how I plan to obtain more realistic training data for the revision, but anyhoo).

On Angle

Using both side view and medium angle in the same prompt is likely to confuse the AI.
Medium angle and side view are likewise meant to be exclusive, however the AI tends to ignore them so try emphasizing them.

Far more important than prompting angle is giving the model permission to adhere to the close-up prompt by omitting legs/feet from the prompt entirely. If you prompt her feet/shoes/thighhighs, you are going to wind up with those elements in the picture and likely her legs up in the air in an unnatural pose.

A Word on Recommended Models

First of all, I could not have created this model without Over the Edge by @freckledvixon and that model is trained on a more varied set of data and can handle a lot of angles. Definitely a must-have in your arsenal.

As for this model, due to the bias in the training data, you may notice more training bleedthrough such as pink and blue neon signs plus rain (if you prompt "night") or black cat ears on the girl. You may find this bleedthrough suddenly appears when switching from a cartoon or realism LoRA to something like Nova 3DCG XL and suddenly the LoRA isn't fighting the model so much. In these cases lower the strength of the LoRA.

All example images were generated only with the LoRA and the checkpoint, 28-35 steps, 4-5 CFG.
