Anata Dake Konbanwa 3

Yoshisuzu Shougo inherits the family house when his grandpa passes away. He shares the house with the maid, Otosumi Youko. Shougo often has intercourse with Youko, but while he is in the half-awake condition that follows the climax, he always gets an image of a gorgeous girl in his head. The girl's name is Reiko, and her portrait hangs on one of the mansion's walls.
