I have a girlfriend that I have been dating for three years. She is my ideal girlfriend who is always smiling and considerate. I met her best friend, Minami and fell in love with her. I know I'm out of character, but I can't help myself. When my girlfriend finds out that she will be away from home for training, I ban myself from masturbation and sex for a month, saving up his sperm to fuck Minami during this time. I was released from my abstinence and fucked Minami over and over again from morning to night during the few days my girlfriend was gone.
