FSET-867 I couldn’t hold back with my brother’s wife, her hair wet from bathing and face bare

I happened to see the face of my brother’s wife with wet hair and no makeup. When the sister-in-law, who shouldn’t have seen her as a woman, removes her make-up, she looks cute, unlike her usual mature atmosphere. Even though she knows that it’s not okay to put her hands on her, she can’t stand her undressed bathing appearance and puts her hands on her brother-in-law.
