083PPP-2532 My friend's little sister is incredibly cute and way too easy to take advantage of, so I wanna bang her (3)

★My friend's little sister is incredibly cute, really friendly, and she shows panty shots and cleavage without any inhibitions!? Is she hitting on me?! I always hang out at my friend's house, but today his little sister is home alone. At first, things seemed awkward, so even with my friend around, I held back. But now I can't take it anymore! Even if I don't confess, I decided to boldly invite her over, and the atmosphere gradually became erotic… She really is into that stuff, huh.
