Jessy Jones - 勢 & 窮

Jessy Jones' right arm.
It reads "sei" (勢) or "ikio(i)" with extra Hiragana "い" and means power or vigor.
An appropriate choice for a pornstar.

His left arm.
It reads "kyu" (窮), usually followed by a common verb "する" (means do). It means to be screwed up.
Not a good choice even for pornstar.
