I always thought these kinds of videos felt sexually exploitative and downright icky, even as someone who likes a good cracking sound. (Can't stand chewing or mouth sounds though!). It feels one step away from the "dirty doctor/sexy gyno" genre in porn (which, unfortunately, is a thing people are into). The placement of the 'doctor's' hands should NEVER be that suggestive, nor anything medical described as 'orgasmic.' If these are licensed chiropractors, I hope people are steering clear. because it is highly unprofessional to market content like this.
