I decided to make Megu Mio-chan, who has no experience with the portio, experience this is the portio! and develop it! When I thrust a bigger dick deeper than usual into her pussy and press it against the portio deep inside, her body, which was attacked by a shock she had never felt before, began to writhe violently! Eventually, a moaning voice like a beast's roar that Megu had never heard before leaked from Megu's mouth, her body became limp, and she ecstatically came! Only in the distribution-limited version, a making-of video where you can see the backstage in high spirits is included!
