Miiro Nanasaki-chan challenged the development of the ultimate erogenous zone "portio" deep inside the vagina! At first, she was confused by the sensation of the portio being stimulated for the first time, but gradually she began to feel horny as usual! Eventually, her body, which was intensely stimulated at the portio spot with a big dick firmly inserted into her pussy, kept cumming over and over again while repeating screams and moans! Only in the distribution-limited version, a special recording of backstage footage full of energy is included!
