Meikko wa Nemuri ♥ Hime
Due to my sister's work, I have to take care of my niece, Akari. I was treated like a creep at university, but Akari-chan took to me. I was relieved to see her grow up, but when we took a bath together, I got a boner from seeing her unprotected! I managed to hold back, but then I saw Akari fall asleep in front of me!
