The first time a cute girl student experiences Ojisan's 18 cm decatin! "Oh, my God! It's big!" While feeling that it is unintentional, take off the rubber and go live! The girls who got decatin's 93 oysters in the Ikase-Makuri made mako from the sunset.

For the first time, all of our schoolgirls were able to experience Ojisan’s 18cm decatin! The first man I saw, Chi-ko, and Decatin! My eyes were getting ten! What is this ... I feel like a size, and to the raw flap of unwillingly removing rubber! "What!? Why?" I don't mind if you turn around! I'm sure you've been decatined!
