Candle Light
Taper candles burn at almost 160 degrees Fahrenheit. That will not give Mei Mara any permanent marks but it is definitely hot enough to scorch her little clit. That does not mean she will not be coming out unblemished. Between the cane, the whip and the iron cage she is locked down into there will be more than enough marks to remember this time by.
