I love low-angle shots that show a single line, but it gets boring quickly when the subject moves on to close-ups of individual parts.
I'd like a shot that includes the whole body, including the face, framed from above.
It's exciting to see the urethra opening clearly, which is often shown off the vaginal opening. It's wide open and very lewd.
Two-finger masturbation is a classic, but I don't see it very often on this site.
Most of the time it's just a one-finger sloppy masturbation with lots of lotion, so it's understandable that it gets criticized.
However, nowadays, the range of things to show off is narrowing, so it's hard to keep a series going.
I think this was a work from a good era.
