You need to create a mask, open the material editor of the dildo, and mask the part that you need to hide.
Something like this: but for Koikatsu.

Do you know how to find that menu in KK? I searched everywhere (I also asked ChatGPT), but I couldn't find it

You need to select the item, and click "Material Editor" in Character Studio

It's called Alpha Mask.

Export the UV to see the geometry of the dildo unfolded on a texture, use that texture as a base to color white the parts you want visible, black the parts you want to hide, save and import as an Alpha Mask (supported by some shaders like main_alpha).

The result will be like this:

In this case I hid a few faces of the ice cube.

I'm not familiar at all with Koikatsu, but can't you just render twice? One with the dildo and one without and then just layer the two in Photoshop? I mean, that's how I would do it in DAZ and it takes literally like 30 seconds to do that work in PS (or your preferred image editor) Seems easier than making custom masks and textures. Just wondering.

A lot of koikatsu-graphics games make use the canned sex animations to record video. much harder to overlay two videos. perhaps that is their problem.
