I've been dating my girlfriend for three years. She's the ideal girlfriend, always smiling and considerate. But then I met her best friend, Minami, and fell in love with her. I know it's wrong, but I can't help myself. From the day I found out she would be away on training, I banned myself from masturbating or having sex for a month, and saved up my sperm so I could have sex with Minami over and over again. Freed from a life of abstinence, I had sex with Minami over and over again from morning until night for the few days she was away.
