[Chinese]ADN-656 Her mysterious older sister, who doesn't talk much, is always in a bra-less state with her nipples visible through her clothes... Ria Ketsuki.

Her older sister is always quiet and you never know what she's thinking. So I find her a bit difficult to deal with. But she's beautiful, and on top of that, she's always braless at home with her nipples erect, which made going to her house something to look forward to. It seems like that older sister had a fight with her fuck buddy and was in a really bad mood. I wish I could be the fuck buddy of such a beautiful woman… I thought, but it turns out she was considering me as a new candidate for a fuck buddy.
