My aunt Yuu was coming over to visit after a long time, and I felt a little nervous. We used to play together and even bathe together, so we'd always been close. Ever since I was young, I'd felt something special for my aunt, always admiring her beauty. Lately, I'd noticed her beauty had only grown more striking, and my heart began to race. While I was in the shower, lost in these thoughts, my aunt suddenly appeared in the bathroom. When I instinctively showed off my grown penis to her, I couldn't help but feel shocked and flustered by the turn of events.
