Marina, a mother of two, harbors a secret: an illicit relationship with her sons. In the living room where the family of four relaxes, she makes Tsubasa jerk her off. In the bedroom, she makes Kenichi give her head. The two sons, each unaware or perhaps aware of their relationship with their mother, use Marina for sexual gratification. Unable to make a sound, Marina is once again demanded by the two today. Silently opening her body, Marina too sinks into pleasure.
