This model can generate videos of pulling butt plugs out. For now this is I2V only. The source image just needs to have an inserted butt plug. This can work on woman, futanari, and probably men as well (untested). This works best when the focus of the source image is the ass.
Note: When generating a video "from behind", the wrong thumb placement for the hand is possible. To avoid this, use a source image with the correct hand already visible. This doesn't seem to happen when the subject is laying on their back or side.
I trained this on 20 512x512 81-frame videos.
