After cleaning the house, I went to greet the neighbors, and there was a slutty sister! I immediately brought her back to the room and drank her right away! I might have been drunk, but I was suddenly welcomed to move in with a double friend! After that, I was called up every chance I got and was double-trained by my sister to become a sadist. Moreover, once all the sisters were unequal and they started educating, they wouldn't stop! I was accused of double-husbanding and double-cake, and I was declared a sadist and became a sister's exclusive dildo!
