"mochimochikun117" specializes in masturbation videos.
The video has the feel of a ``selfie,'' and it gives a nice sense of immorality, as if you're peeking into a secret.

Also, the streamer is a masochist😍
There are many SM masturbation videos that use mischief such as rubber bands and needles on the clitoris.
