Riku, 28, is a former art school student and a young married woman with fair translucent skin and long slender legs. While sketching in the park, I run into her holding the same kind of sketchbook. Her navel-baring mini denim skirt reveals seductive garter-type black stockings, and I can’t help staring. I deliberately bump into her and ask, “Can I sketch with you?” She readily agrees, saying “You can draw whatever you want.” She gets on all fours and pushes her ass out, lets me touch her breasts through her knit top, and even allows me to trace along her crotch — a completely uninhibited outdoor close-contact sketching session in broad daylight.
