Azu, my childhood friend who lives across the street. She has no interest in men and always comes and goes in my room without permission. I thought that our days would continue like that forever... In Kokoro, I always thought that Azu belonged to me... One day, while I was hanging out with Azu as usual, some college guys came to my room and started drinking. Before I knew it, the guys and Azu had disappeared. When they came back, their faces were steamy and their clothes were inside out... I never imagined that she had been having sex with the guys without me knowing... I never imagined that Azu had such big breasts... The ultimate childhood friend NTR!!
