The ending of movie 5. Her relieved expression when filming is over is great.
Although she's overflowing with vaginal fluid, she must have been embarrassed during filming.
I watched Rumi Kimura's works in the order of 2 → 3 → 1.
Number 1 felt like the ultimate version. I didn't expect her to have such a juicy pussy. The milky white love juice was great. I liked the part where she put her breasts on the table and when she was on all fours and her butt was exposed.
