This game is based on the lives of Tyler and Nicole, a married couple, trying to reignite the spark in their sex lives. You control Tyler's actions. Nicole is a freak of nature and loves sex. From time to time, she will ask the MC to cater to a certain kind of fetish. If the fetish is not really your thing, the MC has the option to refuse with only a small penalty to the love stat.
