"yarichinmanman" is a couple's channel run by Tokochan and her boyfriend (?).

Toko-chan says she has "transformed from a former idol into a more gal-like character."
She has a slender body.
Her shapely, beautiful breasts and large butt are sexy.

The content of the video is mostly cosplay sex.
The main focus is on JK-style cosplay, but tight-fitting leotards and very erotic maid outfits are also available.

Aside from cosplay, there are also a variety of other situations, such as handjobs and footjobs where the woman is on top, as well as lovey-dovey sex with lots of conversation.

Another characteristic is that there are a lot of creampie scenes.

[UPDATE 2024-05-21]
The channel name has been changed from "yarichinmanman" to "Tocochan".
