"MistressNatsumi" is a dominatrix-themed channel run by Natsumi.

Natsumi is a beautiful black-haired woman with a slightly mysterious and sexy aura.
Since she is a dominatrix, she does not take off her clothes, but the deep cleavage suggests that she has big boobs.
Her big, beautiful butt is also good.

The content of the videos mainly focuses on anal development or soft SM.
Of course, it is the man who has his anus developed and is restrained.
The video shows Natsumi's exquisite verbal abuse and skillful techniques.
There are many men appearing, moaning shamelessly during anal sex with strap-ons, etc.
The content may be a bit harsh for anyone other than those who enjoy being dominated by beautiful women.
However, I think Natsumi's seductive expression and her verbal abuse, which is mixed with fast and slow, have an erotic quality that will excite even people who don't share her tastes.

There are over 100 videos, but the playback time is short, ranging from about 30 seconds to 1 minute.
The length may not be enough for those who like dominatrix type videos, but I think it is an easy-to-watch length for those who don't like them.
Also, Natsumi's costumes are generally tight-fitting and very erotic.
I think it's worth watching just for that.
