My step-sister, who suddenly appeared in my life, is simply busty and beautiful. However, because her breasts are too big, I don't know where to look. So, when I try to keep my distance from her, she says, "Haven't you been avoiding me lately?" Instead, she tries to approach me even more actively! As a result, she makes an attractive proposal: "Why don't you try taking a hot spring at my house?" That means...? C-o-n-y-o-k-u? Mixed bathing? Eeeeh!? She's prepared everything, even a bucket and sake! I'm going to take a bath with her... Has my drunken step-sister gotten horny...?
