So far I only found two photos with this spiked harness. And then in august 2021 I found this FemDom photo that seems to have been using the same harnas.
In January 2022 I found another photo (see the 4th one in the gallery) with a close up from the harnas and a different female model. The corset the Dominatrix is wearing can also been seen in the post Rare Corset, while the gloves appear in a lingerie shoot for Diana Slip Lingerie, captured by Roger Schall.

This has to be the ultimate chastity, not belt but, device!
It would be dangerous to come near anyone wearing this 🙂
