RK-004 - Rankiryu 4: The screaming girl, a brutal scene of branding with hot wax

This is a hardcore SM series. There are no sexual elements at all, just a dominant S tormenting a submissive M. I don't know how the M ended up in this, but they clearly look like they hate it, are in pain, and are suffering. I bought it because the thumbnail looked softer than other works in the series, but I'm dissatisfied with the short runtime. I wanted to see more of the single-thong torture whip rather than those painless split-tip whips. Not for getting off, but recommended for those who want some intense stimulation.
