She's just a female friend who meets up every week and has sex. Sex buddies? Best friends? The compatibility of their sex, which is based on their sexual desires, is on another level! They hate not being able to have sex once a week, so they end up restricting each other! The two of them can't stay apart, and they have a real, intimate sexual encounter! The most satisfying ejaculation is when they get close to each other and have a sticky sex session with a woman who has the best physical compatibility.
