Ideas for a full-size headboard to convert for bondage?

So, for those of you have aeady come to know me, I am a 38, almost 39-year-old autistic male living in an apartment with his parents but anyway, this week, I got a new bedframe and am looking for ideas for a DIY headboard and footboard that can work for bondage but can have the bondage features hidden away. While I cannot find the frame I got on the Walmart website anymore, the frame has the same kind of holes on the ends of the legs as this one. https://i5.walmartimages.com/asr/8ac7ebe...nBg=FFFFFF

Is there a full-size headboard and footboard set that I could modify? Any help would be appreciated. Thanks.

I would make a 2-piece wood board with 5 holes (or more) the appropriate size for neck hands and feet and then fill those holes with decorative wood discs with engravings or bas-relief to hide their actual purpose.

It would be more difficult to hide the locking mechanism, but maybe you can use the ordinary mouning bolts and deny yourself access to the wrench/screwdriver for the duration of bondage.

Fun idea.
