One day when my parents were away for 3 days, my cousin Erika Arimura came to my house to play, ready to study because my house was right next to her school. Every day living next to my beautiful young cousin, she wears extremely tight clothes at home to reveal the curves of her body, making me always want to have sex with her, FA for so long that I always want to have sex. Living with such a sister for 3 days made me unable to hold back my heart anymore...
