Was going to give it 4 stars, but found better versions of this author's animations (thx, @bros987). The author's features can be called attention to detail and love for gangbang (well, it's for the amateur). It's also cool that many of the works have a mini-plot. Not critical, but I don't like the effect of blurring, which author uses for the image of acceleration (increasing the frame rate is preferable).
