I have a girlfriend I love, but I met her sister "Eimi" and drowned in sex. She knows she's out of her way, but she can't control herself anymore. Masturbation and sex are prohibited for one month when she vacates her house, and she collects her sperm enough to burst her balls in order to roll up with "Eimi". Released from her ascetic life, I and her "Eimi" cummed out from morning to night until she got pregnant for several days without her.
