A Lora to get the classic leather harness that forms a X with a ring at the center of the chest rather than the more common H style harness.

Trained with a few images that has an additional strap that is attached to a cock ring.

Trigger word: "X-harness".

Do not put "leather harness". That seems to generate the H style harness that is more common in most checkpoints.

To get the cockring strap, add "with cockring strap". Doesn't always work.
