"kei_sana" is a couple channel run by a male named "Kei" and a female named "Sana."

Kei is in his late twenties and Sana is a 19-year-old college student.
This couple with a large age difference shows us an erotic video.

Sana has a very slim and slender body.
However, she doesn't look skinny, and has a slim yet beautiful body line.
Her small butt and toned thighs are cute.
Her breasts are small, but they have a nice shape and pink nipples.

The content of the video mainly consists of somewhat rough sex.
It's a couples channel, but it's not a lovey-dovey channel.
Most of the content involves the man doing the heavy lifting and the woman feeling great, but there are also some SM-style Gonzo in which the woman is restrained with ropes and handcuffs.
Another notable feature is the large amount of "G-spot stimulation" that is not often seen on other channels.

Sana gives off a pure and innocent impression, but in every video she shows off a wild and wild side of herself.
Her intense moans (including moans) and the way she wriggles her slender body are unbearably erotic.

Another feature is that there is a lot of cosplay sex, and you definitely don't want to miss Sana, who was a high school student until recently, in her uniform.
Other styles include sexy maid outfits, Chinese dresses, and anime-style cosplay.
Recently, threesome videos in collaboration with cosplayers have also been released.
