PJSLIDE - Intentional non penetration LoRA.

Works on LTX 2.5 as well

This was trained on 10Eros v1.5, which is an LTX 2.3 fine-tune, but it loads and runs on LTX 2.5 too. The two share 2624 of the modules a LoRA adapts with no shape mismatches between them, and it has been reported working on 2.5 in the field.

Start at the settings below and adjust from there.

Quick start

Base model 10Eros v1.5 Trigger PJSLIDE Strength 1.0 CFG 1.2 – 1.3 Length 12 – 20 seconds Start frame one already in contact

Performance: [PJSLIDE. She slides her pussy up and down along his cock, grinding
down hard on him and speeding up. He is close and about to cum. He cums hard, and
a big thick load of white cum shoots out of the tip of his cock in strong spurts,
pumping out again and again and pooling all over his stomach. She keeps sliding on
him and spreads the thick cum with her pussy.]

Sounds: [Wet sliding sounds, he groans loudly as he cums, she moans]

Example renders were 1000×1000, 20 seconds.

Getting a start image — read this before you give up

I nearly abandoned this release because I couldn't make a usable starting image. Every model forced cowgirl-with-penetration, or had her hovering in the air, or holding it in her hand.

The magic word is sumata (素股). It's a Danbooru tag, so Pony and Illustrious know it natively, and it means this act specifically, without penetration. Realism checkpoints that aren't Pony-based ignore it completely.

Checkpoint RealPony v1.10, or any Pony-based one LoRA Cowgirl Pussyjob w/ Hand Support — civitai.com/models/1065556

Positive:

(sumata:1.4), (grinding:1.2), girl on top, she is straddling him, he is lying on
his back, (erect penis pinned flat against his stomach:1.3), shaft trapped between
her vulva and his belly, she is sitting all the way down on him, hips lowered,
bodies touching, glans poking out past her mound, (both her palms braced on his
chest:1.4), close-up from the side, photorealistic

Negative:

(vaginal:1.4), (penetration:1.4), (insertion:1.3), hand on penis, holding shaft
upright, handjob, missionary, on her back, hips raised, gap between bodies, oiled,
wet skin, worst quality, deformed hands

Batch 30 and pick — about one in four works.

Three traps: keep girl on top out of the negative, it's the position you need. Don't write "hands flat on his chest" — flat jumps to her chest. And leave wet out of the positive unless you want them both varnished.

Four things that will save you time

None of these are this LoRA — they're LTX-2.3 behaviours and you'll hit them with or without it loaded. They cost me a whole evening, so they're worth writing down.

1. Word order decides whether he finishes. Write it as a sequence — she slides, then he cums — and the model treats cumming as a later event and defers it past the end of your clip. Tie it to the action with "as", or state it as already happening.

2. Never write a negative into the prompt. I wrote "never pausing" to stop her hesitating and got a six-second pause. The model reads the words that are there. Write grinding continuously, not without stopping. Unwanted things belong in the negative prompt.

3. Sound goes in its own block, and match the clip length to the line. Put "he grunts loudly" in the visual description and you'll get a render where he says the words — keep foley in Sounds:.

If you do use Dialog:, the clip length has to suit the line. Give a short line 25 seconds and he'll repeat it five or six times to fill the space. Too short and they gabble it. Match the two and it lands once, properly.

4. If the trigger shows up as text on screen, drop it. LTX does that with tokens it can't attach a meaning to. Try lowercase, move it off the front, or leave it out — the LoRA applies when it's loaded.

Volume and speed are both yours. Ask for a little and you get a little; ask for a huge load and it goes absurdly big. "She slides quickly" genuinely speeds her up.

Your start image doesn't have to be perfect

The cock doesn't need to be visible at all. I've had several work from frames with nothing there — she's simply in the right position, and as she slides it appears naturally and in the right place. Get her pose right and the anatomy follows.

It will also pull him back out. If your frame has him inside her, this takes him out and starts sliding. Every frame after insertion was cut from the training data, so there's no "inside" state for it to continue.

Frames already in contact start moving within about two seconds. Ones with a gap are slow to get going — it continues an action far better than it starts one.

Known limits

Her on top is what it knows. Every training clip is her above him, shaft pinned flat, grinding front to back. Missionary or him-on-top falls back to the base model.

Cum can come from the wrong place if the tip sits flush against her. Pick a frame where the tip clearly reads as part of him — even mostly buried in his pubic hair — and it's fixed.

Don't overbake it. The whole ladder is included. I use 9000. By 14000 it stops generalising: it sits still on unfamiliar frames and invents poor anatomy. Later is not better.

Long renders drift. Trained on 2-second clips; 12–20 seconds is the tested band.

Every clip was cut only to the seconds where the slide is actually visible, and everything after insertion was thrown away — that's what keeps it outside. Each group carries one identical sentence; variety comes from the scenes, not the wording.
