Well, after watching the latest 3 releases of KV. I can safely say = 205 > 206 > 207.
207 features the very skilled Hitzuki Rui, and ex-S1 Misaki Kanna. In the paper, it should have been the best one but somehow ended up being up a bit dull. Or maybe because lately, I value more the creativity… Anyhow, they did the blowjob fetish in the club this time.
