Competent and pretty, Yui is a girl who even her coworkers are envious of. She's got a great job, but possibly because she's a bit overconfident, her relationships don't last, and she doesn't have much of a personal life. The one person who's always been by her side is her childhood friend, Akira. He's kind of a pushover when it comes to Yui. She'd always thought of him as a sweet kid, like a younger brother... but when she trips and lands on him and accidentally kisses him, it triggers something in him that turns him into a hungry beast! He wants her body and teases her while whispering into her ear how wet she's getting. He's not the Akira she knows at all...!
