“onyx kim” begins in a sunlit bedroom where a petite blonde reads erotica aloud. The words make her squirm; soon “onyx kim” shows her setting the book aside to touch herself through cotton panties. In “onyx kim”, the fabric darkens with arousal before she pushes it aside, exposing glistening pink. Delicate fingers dance over her clit in “onyx kim” while her free hand pinches a nipple hard. The build is torturously slow in “onyx kim”, breath hitching, until she finally plunges inside, fucking herself to a shuddering, toe-curling release that leaves her giggling and glowing in “onyx kim”.
