Lately, I'm running out of money because of my niece Natsutsuki... but when I'm seduced by her remarkably growing breasts, I just listen to what she says. One day, when I learned about Natsutsuki's wasteful spending, I was frustrated with my lack of money and my big tits were at their peak. When I came this far, I couldn't go back anymore, and because my parents weren't there, I messed up with my niece many times. Even so, Natsutsuki didn't regret it, but instead made fun of me, saying, "I was a virgin."
