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%.'' Both of us have 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. My younger brother's cock is getting erect. Well, it can't be helped since he's a virgin, but he's completely turned on. - What's even more surprising is that the older sister is embarrassed by that bottle and gets excited, but after that, it develops into so-called naughty incestuous sex.I'm glad that she graduated from virginity and that the relationship between the siblings has deepened! - That's what I'd like to say, but I'm worried about their future family relationships. - At first it was intended to be a barati, but from now on I'm going to follow this brother and sister as a documentary lol
