I'm not sure why but I feel this type of NTR story it doesn't really suit the yuri genre. I'm feeling too much confliction between the characters and what I'm what I feel about this series as a whole. I feel that the "yuri genre" is a place that primarily consists of female characters and perhaps some occasional male characters one the side (however they never play a large role or involve themselves in the romance). This series, on the other hand, brings in a mix of Het and Yuri with some Abuse that makes it hard for me to root for a specific pairing. In my opinion, yuri is best left to a relationship between two female characters without negative interference from male characters.
