The first scene is set in a “dark” (not too dark, like a summer evening) place to give it an eerie feeling, probably a dungeon-like set. If it isn’t dungeon it’s not that important. There’s a bed in the room or somewhere where they can… make out later on.
Anyways, the girl is restrained and has been there for a while in a somewhat uncomfortable position, being unable to rest properly. Neck tied to a pole with a collar, or just hands tied behind her back… legs tied too? Should be restrained, but not too much because it breaks later on. She shouldn’t be in top condition as she’s been there for weeks, but not dirty either.
Someone walks in… it’s the domme. She walks up to the girl and is being all condescending – like pulling up the girl’s chin to make her face her, smelling her, and overall inspecting her. Her actions are basically saying “I’m in charge!” and showing who’s boss.
In the end, she does “her thing”, meaning “torturing” the girl as in forced orgasm, licking. The domme does it to please herself (could be done with toys if necessary) After a while the girl *almost* passes out but is able to stay conscious until she starts to leave. She’s done for the day.
However, as the domme’s walking toward the exit the restraints breaks loose and the girl is able to break free (fairly quickly?) overpower the domme, perhaps pushing them both toward the bed (somehow?) The girl comes out on top. It’s a quiet moment – domme realizing the position’s been reversed. She’s now on the “recieving end”. It ends up with the domme slowly pushing the girl aside who allows it of course as she secretly liked being “tortured”. Domme starts slowly taking charge again. In the end they’re equals. It ends with some lesbian action – nice balance between hc/sc.
