Your sole pics
Hey bro, most ticklers will want to see two things:
(1) a full-on pic of both soles, showing the whole length from toes to heel
(2) a closer-up shot of the balls and toes, so they can see what the skin is like... thick, or soft, etc
You didn't say what kind of tickling you're looking for, though... Feet? Pits? Belly? All of the above? (evil grin)
