My aunt, Sonoda Takako. At school, she's beautiful, kind, and the ideal school nurse. But at home...she's messy and careless. She also likes alcohol and mischief. Due to my parents' work schedules, I ended up staying with her. One night── I waited until Takako was asleep, and as I was clenching my penis to masturbate... "Hey! I tried to approach you quietly! How's it going? Are you surprised?...Oh...oh my...oh my?" Takako burst into the room, her grinning gaze fixed on my crotch. "Um, sorry, I'm going to put this away, so could you please leave..." But Takako didn't leave the room. Instead, she sat on the bed and started smiling. "Okay, then, why don't you continue? I'll accompany you from here on out...♪"
