Based on a pixiv tag スケベ板, which character holding a mysterious frame in body check and got pregnant through wormhole.

v0.4 is much better trained and only for straight-on angle. If you want to try making different angle, you may try v0.2, see v0.2 "about this version".

Test in most model, such as AutismMix confetti, 7th anime pony, boleromix, Hard pony, SakuraRain, Featureless Mix Pony v2, AnimagineXL 3.1, T-ponynai3-v6, Speciosa 2.5D, XL_e4P_Mix.

Recommend lora strength: 0.9
Trigger tag: holding lewdframe / against_glass / breast_on_glass
Trigger strength: lewdframe<holding_lewdframe<<<holding lewdframe<<<<<against_glass<breast_on_glass
#it is possible to use only "against_glass" or "breast_on_glass" as trigger
Optional negative tag: (small_lewdframe, long_lewdframe:1.1), drinking glass
other trained tag: holding small lewdframe, holding long lewdframe, wet crotch,
Suggested usage: Put the "prompt" + BREAK before character description for lower style influence. Put the "prompt" in the middle is easier to make "thigh press".

When to use "lewdframe, holding_lewdframe" / "holding lewdframe":

Although "holding_lewdframe" is very weak prompt, it has higher purity in making the frame. Meanwhile, other quality prompt would weaken "holding lewdframe" . You should use "holding lewdframe" when you use very little prompt AND use "lewdframe, holding_lewdframe" when you have many prompt to describe the character.

For perfect frame:

Based on your character's height and clothing, the frame may be missing around neck OR split into two parts OR incomplete.
- IF the neck part is missing, do not use "(small_lewdframe, long_lewdframe:1.1)" in negative, reduce your character lora strength, OR increase the strength of lewdframe lora, use (lewdframe, holding_lewdframe:1.4).
- IF the frame split into two parts, especially form a smaller frame around the head, put "(small_lewdframe, long_lewdframe:1.1)" in negative.
- IF the frame is incomplete, lines are not straight, increase the lora strength or use (lewdframe, holding_lewdframe:1.4)
- IF the character holding a glass of drink, put "drinking glass" in negative.
- IF the frame get wet or steaming, put "bathing" in negative OR use masterpiece/source_9 prompt.

Covered breast:
"breast_on_glass" and "against_glass" usually give nude nipples. In order not to make the character nude, reduce their strength to (breast_on_glass, against_glass: 0.3) OR put "nude:1.2" in negative, OR use solely "(lewdframe, holding_lewdframe:1.3) "

Navel:

This lora tend to make penis in navel part. If you do not want them, describe the navel part with clothes, "navel", "covered_navel" OR put "uterus,penis,x-ray,cumshot" in negative.

Prompt effect details:

"holding_lewdframe:1.0" is a very weak prompt to make frame, but influence the style when push too high. Use BREAK to single it out.

"breast_on_glass" and "against_glass" are responsible to make the "thigh press" against the glass. If you not getting it, gacha it. They also make the hands not grabbing the lewdframe.

"nude" is responsible to x-ray vision, but the type of clothes that could be clean is limited to training data. mostly sleeves, gloves, dress, skirt, collered shirt. v0.4 is weaker than v0.2. If you really want to make the character partially nude, use redraw region with lora strength 0.9 + noise strength 0.9 + (completely nude, nipples, navel).

Prompt that affect the hand gesture such as "holding", "holding glass", "arms at sides", "hands up" would give weaker result.

"wet crotch" is trained for all situation of cum overflow through pant and dress. Do not think it is only for wet pant or wet cameltoe.

"holding_small_lewdframe" is trained for a frame only cover the breast, AND "holding_long_lewdframe" cover from head to toe. BUT they are 10 times harder to get due to the limited training sample.
