In the Erotica game, you are a recent college graduate with a lot of free time on your hands. Your reclusive uncle George, who's been living in isolation for a while, has decided to embark on an extended vacation of several months. He offers you the opportunity to house-sit for him while he's away, and you eagerly seize the chance to make some easy money and experience life in a new place. It's your last hurrah, a period of enjoyment and socializing before the responsibilities of real life kick in. You haven't been in touch with the people in this town since your visits when you were younger. However, as you approach the town's borders, you spot a familiar face - a young girl named Riley. Quickly, you rekindle your friendship with her. Recognizing that Riley is going through a tough time, you extend an offer for her to stay temporarily at your uncle's place in exchange for her guidance in getting to know the area and introducing you to her friends. In no time, you find yourself meeting her best friend, the spontaneous Lilly, her step-sister, the enigmatic Heather, and a host of other individuals, each with their unique stories and personalities.
