Magic Eyes - Gokusai Uterus Duo (Uterus Sex)

You've known the two sisters in your neighborhood for ages. The older sister is already studying, the younger sister is still at school. The family is very spiritual and conservative. From time to time, you tutor Nemu, the younger sister. While Nemu is working on your tasks, you also have time to talk to Yume, the older sister. One evening, Yume asks you if you have a date for the weekend. You are surprised, but answer no. She invites you to dinner. Their parents are out of the house at an event. While they are away, someone is supposed to look after the two girls. On the evening planned, the sisters' mother greets you at the front door. The parents are wearing black robes and lots of jewelry with mystical symbols. They tell you that they are just about to leave and thank you for looking after them. Nemu comes to meet you and greets you as the parents walk out of the door. The usually conservatively dressed girl is wearing black make-up and eye-catching, frivolous clothes. Yume also greets you in the kitchen. At the sight of her, you briefly close your eyes in disbelief and shake your head slightly. She is also wearing black make-up and a very thin dress. You can see very clearly that she is otherwise only wearing a very small black thong. Apart from that, the sisters are behaving completely normally. After dinner, Nemu leaves the room first. Yume gets up and takes you by the hand. You follow her into a bedroom. Candles are burning and Nemu is lying on the bed. Yume lies down next to her. In a split second, you realize what is happening. You are the chosen one. You are the one to prepare the girls for their future lovers.
