I'm a big fan of Femdom Army stuff in Reese videos. She is very violent and and slaps/punches forces the slave to smother.
I'm also a big fan of escalating bondage. Start with just sitting, slave tries to obey but then gets scared starts to struggle. Some pain compliance (the mentioned slaps/punches) goes on for a bit and then the Mistress brings bondage into it. Maybe rope, maybe duct tape, cuffs whatever. Smother again... again slave panics and gets air. Maybe escalate again to tighter bondage or stuffing the mouth with a gag of some kind.
There's not enough head-in-pantyhose facesitting in an amateur setting. I want to see more of this by women wearing normal clothing, white panties, full back, natural or black pantyhose, domestic setting, close-ups.
... also, how about head-in-panties too. I once saw a Japanese mistress and she facesat me first with head in pantyhose and then she eased my head into her knickers, it was fantastic. This would be good to see in a video too, again domestic setting, none of the femdom cliches.
