<h1 id="restraint-pussyjob-sumata-grinding-no-penetration-+-audio">RESTRAINT — Pussyjob / Sumata / Grinding, No Penetration + Audio</h1>She slides along him instead of taking him inside. The shaft stays pinned flat against her, she grinds back and forth along it, and you can see her labia part and her clit compress as she moves. It stays outside the whole time.That's where the name comes from — this is the act two people do when they've decided not to do the other one.Video + audio. It generates its own — wet sliding, breathing, the lot.<hr /><h2 id="quick-start">Quick start</h2>Base model10Eros v1.5Trigger<code>PJSLIDE</code>Strength1.0CFG1.2 – 1.3Length12 – 20 secondsStart frameone already in contact<pre><code>Performance: [PJSLIDE.

pumping out again and again and pooling all over his stomach. She keeps sliding on
him and spreads the thick cum with her pussy.]

Every model forced cowgirl-with-penetration, or had her hovering in the air, or holding it in her hand.The magic word is <code>sumata</code> (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.CheckpointRealPony v1.10, or any Pony-based oneLoRACowgirl Pussyjob w/ Hand Support — civitai.com/models/1065556Positive:<pre><code>(sumata:1.4), (grinding:1.2), girl on top, she is straddling him, he is lying on

Don't write "hands flat on his chest" — flat jumps to her chest. And leave <code>wet</code> out of the positive unless you want them both varnished.<hr /><h2 id="four-things-that-will-save-you-time">Four things that will save you time</h2>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 <code>grinding continuously</code>, not <code>without stopping</code>. 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 <code>Sounds:</code>.If you do use <code>Dialog:</code>, 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.<hr /><h2 id="your-start-image-doesn't-have-to-be-perfect">Your start image doesn't have to be perfect</h2>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.<hr /><h2 id="known-limits">Known limits</h2>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.
