It's been a year since his father committed suicide after being laid off. The son and his second wife, Aoi, were poor but trying their best to survive... They sold their house and moved to a one-room apartment where they could live the bare necessities, and started a new life... but the room was so small that their bodies were pressed together! The son's libido was on the verge of exploding, sensitive to the pleasant smell of his young stepmother's hair and the soft feel of her breasts and ass! Can the two escape from this one-room trap?
