Like, does anything besides spanking happen in this game? Is there even Bondage cause BDSM literally includes the word by definition and after 6 hours there is like only nudity and spanking. What the fuck. And holy fuck why the goddamned grind for nothing?!?!
There is no real bondage in this game, no.
But while the "B" in "BDSM" is usually expanded to bondage, "BDSM" is not a monolithic fetish but a buffet of playthings to pick from, and not everybody puts everything on his platter, so neither bondage, nor dom-sub, nor sadomasochism are individually needed to be BDSM, only some of them have to be there.
Also, despite many games catering to that, not everything has to be taken to its logical extreme to be included in/to satisfy a fetish. You can have DS roleplay (IRL, in game it may be real but the game is the roleplay) in your bedroom, in your whole house, or be parading each other around on a leash in the streets. All BDSM.
So in essence, this is BDSM, even without bondage, but you'll probably not find what you are looking for. Though of course only that Gen X guy knows for sure what will and won't happen.
