Snow Daze: The Music of Winter

Play as a young musician named Jason that is banished to the attic because he lusts after his milfy mom and three hot sisters. He lives mostly to play his cello and tinker with mind control technology. He pursues his older smart sister named Kira, his sporty twin sister named Jane, his flirtatious and carefree younger sister named Sarah, and his curvaceous mom Noelle. A blizzard happens and they're snowed in so he takes advantage of the whiteout and puts his musical talents to use. He plays subliminal audio files through the floor of his attic room at night that will let him put the girls into a trance during the day. This doesn't give him unlimited power, however - he still has to gradually break down their inhibitions to get them to do what he wants. Will they do what he wants? That's up to you!
