This is a screenshot from a foot fetish based JAV. The main concept were 3 different patients entering a clinic each with different injuries.
The first gentleman enters with a head injury. I don't remember the inbetweens, but eventually the man ends up sucking on the nurse's toes, which leads to a footjob, which leads to them fucking. That's where this screenshot takes place. IIRC, the nurses were slightly taller and had bigger sized feet and were all tan. I know a similar concept has done in another dvd that featured watersports, but there is no watersports in this video at all.
The next scene dealt with someone with a leg injury. The nurse forces him to lay down, and give him a footjob while she sits on the chair teasing him. It is a different nurse, but still tanned and big footed.
I can't remember the third scene as much.
If I recall, the studio had this faint green and blue lighting. I've seen it in other JAV foot fetish vids before, but I can't nail down what the name of the studio is.
Going to open the catalogue now and see whom I can help.
