DNJR-099 I'm Not Popular And I'm Impotent, But Thanks To My Neighbor's Older Sister, I Awakened To My Piss Drinking Habit And Was Able To Graduate To Virginity Asuka Momose

I'm a virgin and unpopular, and I've never talked to a woman, and I was worried that I wouldn't get an erection even when I saw erotic images and videos. One day, she becomes friends with a cute and cheerful older sister who moves in next to her, and she gets drunk and talks about ED. For the first time in my life, I feel excited because of the ammonia smell of pee that I feel from my sister's panties who listens to me with empathy! Then the older sister said, "Then why don't you take a look at the real thing?"
