Sanjo Rina, a dark-skinned gal, secretly has feelings for Narazaki Zen, her childhood friend who is younger than her and uncool and boring.
Zen is forced to cosplay as a bear, and Rina is soothed by the sight of him.
They've been playing dress-up since they were little, and as an extension of that, she's been sucking Zen's dick. They
've been doing that for a long time.
But Zen says he wants to end their relationship.
With a sense of despair, Rina tells him her true feelings.
Because he's Zen... I want to dress him up.
Because he's Zen... I want to have sex with him.
And so, the two finally understand each other's feelings, and become immersed in a world of love and romance.
黒ギャルの三条りなは、ダサくて冴えない年下の幼馴染・楢崎善に密かに思いを寄せていた。
善はクマのコスプレをさせられ、その姿に癒されるりな。
○○の頃から着せ替えごっこをして、その延長で善のチ○コをしゃぶっていた。
ずっとそうしてきた。
だが、もうその関係を終わらせたいと善が言う。
りなは悲壮感を漂わせながら、本当の自分の思いを伝える。
善だから…着せたい。
善だから…エッチしたい。
そうしてやっとお互いの気持ちが通じ合い、いちゃラブな世界に没頭する二人。
