Even though I have a girlfriend I love, I met her sister, Eimi, and became addicted to sex. I know it's against the rules, but I can't control myself anymore. I forbade myself from masturbating or having sex for a month while she was away, and saved up so much sperm that my balls would explode so I could have sex with Eimi. Freed from a life of abstinence, Eimi and I had sex from morning till night for a few days while she was away, cumming inside her until she got pregnant.
