Yura, a simple-minded girl, finds pleasure in making a man ejaculate because of a back-op recommended by a customer at a refreshment where she works. Since then, she has thoroughly mastered the techniques to make a man squid, and she is more obsessed with making squid than money! ? The back option is getting more and more extreme, so that SEX will be done without permission! Even if you ejaculate, even if you blow a man's tide, even if you make Yura squid... "I won't stop back ops until Yura is satisfied!"
