Siblings compete in a baseball fist showdown for a big prize! Older sister: Mana, 23 years old (shop clerk) Younger brother: Masashi, 22 years old (virgin) ``Well, I think it's okay. We're family, after all.'' ``I don't think I'll get an erection 100%.'' We've both become adults in mind and body. Now, I'm trying to plan a project without knowing that that logic doesn't work. I could have predicted it a bit, but I retract my previous statement lol
