Trigger words

FingerInside ?????
FingerInside ass

Zoom level control:

closeup

This works somewhat, but isn't necessary, feel free to skip. But if you want close-ups, try the closeup keyword.

Additional trigger words that can help the concept:

finger
fingering herself
fingering ?????
fingering asshole

The preview images are certainly cherry-picked, but overall the model produces good results.

Compared to the SDXL model, this one is under-performing. But I haven't really dialed in my Comfy settings yet either so it may be alright.
