Forewarning - this definitely did not come out as well as I would have liked but after many hours of tweaking and re-training I'm releasing it as is. It does an OK job IMO but could/should be so much better.

Core concept is a person presents the viewer a male chastity device.

base prompt is:

c0ckc4ge. A woman presents a metal male chastity device.

or for plastic

c0ckc4ge. A woman presents a plastic male chastity device.

The model works much better if you're specific in the shape, color and details of the device. I'd suggest these additional prompts:

Classic metal:

The device features a spiral design, with coiled chrome metal bands creating a cylindrical shape. The base is a flat, circular, shiny chrome plate, with a small bronze padlock attached to the base. The metal bands are tightly wound, giving a textured, ridged appearance.

Flat metal:

The device features a circular, flat, silver-colored top with five or six evenly spaced holes forming a circular pattern. A small, silver-colored metal hinge is attached to the side of the device.

Classic plastic:

The device features is translucent pink. The device has a phallic shape with smooth, glossy textures. The device has a small open slot on the end of the phallic shape.

It should support a variety of colors/materials so definitely experiment.

If any other LORA creators have thoughts or ideas on how to actually get this to be better I'm all ears. Happy to share dataset/captions etc.
