A bully girl from her school days who appeared after calling a delivery health girl who was not allowed to have sex

To release my accumulated sexual desire, I called a delivery health service and saw a girl from the school caste "Volume" who bullied me during my student days! That bullying girl, Mukai, is now groaning in front of me... Perhaps this is a chance to dispel dark history? It may be in return for being bullied in the past! And I can do something sexy with Mukai-san... That's amazing, I'm getting a little excited lol Okay, I'm bullied lol
