Having an older sex friend is great. No need for the troublesome process leading up to sex. You can do plays that a girlfriend would never agree to. A carefree physical relationship with a boss in her thirties who's head over heels for you... but then she says, "If you marry another man, will you give me your seed?" A sex friend who married some random guy and became a housewife, starting raw vaginal sex without a condom. Days of breeding sex begin... Based on the popular doujinshi "Edogawa Roman", fully realized in live-action by Shinoda Yu!
