Sakura and I have been in love for a while and are preparing for marriage. She has a younger sister named Mahina. Mahina is truly beautiful, cute, and her seductive G-cup breasts captivate any man's gaze. Since she was young, Mahina has always wanted what her older sister has, which makes their mother struggle whenever she buys things for both of them. But it seems like she wants to have more than just clothes that belong to her sister. Today, Sakura is traveling with friends and will be away from home for three days. That night, Mahina came to stay at my place temporarily because she was coming home late from school without any clothes, so she wore Sakura's clothes. The outfit seemed quite loose, revealing her full breasts in front of me!!! She also noticed me looking. She then approached me, placed my hand on her ample breasts, gave me a sweet kiss, and started seducing me! Even though I knew it was wrong, I couldn't resist her and ended up passionately making love with Mahina for three days while my girlfriend was away...
