From Spanking Art

Ruka is a contemporary Japanese spanking artist. Ruka draws child spanking art, usually bare bottom and OTK. Her main pairing is M/m, although she draws in all pairings occasionally.

Ruka's style is somewhat sketchy and computer colorized, possibly directly drawn in digital using a graphics tablet.

Ruka's art can be viewed online on the artist's site (see link below) and in membership sites such as Anime OTK.
