Riona Hirose is a little devil of an older sister who, despite her cute expression, curses men with her harsh Kansai dialect. Men gather around her because they can't help but want to be tormented by her harsh Kansai dialect. 'I won't accept anything less than thick, concentrated semen!' The M-men try to satisfy Riona-san, endure intense teasing, and hold back until their balls are swollen with special concentrated impregnating fluid, which they can then shoot into her pussy!
