This isn't even a BDSM, it's just them using sex toys like how you normally use it
i think it’s more the degradation aspect of bdsm and less the ropes and whips part.
Imo that tag is bc their dom/sub dynamic and how he controls everything she does
This absolutely is a form of BDSM. It’s not all flogging and beating each other to get off. Free use is what this is catagorized as and it is fairly common as a kink.
