Why is Koka-sensei, the female teacher of my dreams, living with me? Suddenly, Koka-sensei, who I had a faint crush on, becomes my sister-in-law and we end up living together! At school, she is a pretty and clever teacher, but at home she is a dried-up woman who drinks beer after taking a bath! She is an unaware seductress, wandering around in her light loungewear and flashing her buttocks and breasts! She gets a full erection at the sight of her different appearance from school! She whispers in your ear, masturbates while being watched, has sex secretly in the living room, gives you a titjob with encouragement, and has sex with you inside while being wrapped by her big sister!
