I have a girlfriend who has been with me for three years. She is always smiling and considerate, the ideal girlfriend. However, I fell in love with her best friend Minami. I know it's wrong, but I can't control myself. Knowing that she would be away on training for a month, I abstained from masturbation and sex for that entire period to save up sperm to have sex with Minami as much as possible. Freed from my abstinence, I had sex with Minami repeatedly from morning till night during the days my girlfriend was away.
