A pure and innocent 19-year-old who hasn't been tainted by anything. With a petite body of 149cm and an I-cup bust, she has a miraculous proportion. Although she is shy, once the switch is turned on, she goes from an 'innocent' expression to an 'adult' expression. While passionately moving her tongue, she dives into sex with all her heart. Her high sensitivity, causing her to squirm with pleasure... A yet-to-be-explored busty girl, Yuimi Shion, I look forward to working with you from now on.
