Seeing her at a school

I'm visiting Japan for the first time and is intrigued by everything they have to offer. From the nude onsens to sushi and ramen. There are so much I don't understand and so much I like about exploring this new land. I walk past what I think is a grade school and come across something odd.

A young girl are standing surronded by like 6 other guys all looking at her and two of them have a cameras. Mmmh interesting maybe it's some sort of advertisement for the school uniform/clothes. I decide to watch by the side line and to my shock the young looking girl starts to unbutton her shirt and she doesn't stop. Only for her to pull it open and show her surprisingly supple breasts. I didn't expect that from a grade schooler. Still, this is wrong and I must intervene, I can't let these pervs exploit a young girl like this.

I walk up and pull one guy away from her and then steps in standing between them in a defensive posture. I stand with my back to her and look at the other guys with a grim expression. I tell them in broken Japanese to stop and that this is wrong as well as the word kid. At first the guys seems scared and hostile, only for them to start laughing. It seems the girl behind me is peaking out from the side telling them to relax. One of them took photos of all of this.

I end up turning around to face the girl that not steps forward as well. She giggles and laughs and says "Thank you! You are a very brave man, a real knight, haha, but this is my job and I'm not a kid." As she said not a kid she kind of pushes her chest forward as to show of her rack and I can't help to look down at it. Only for her to giggle and blush. "You see I'm a adult model, with a young looking face." Her hands move up and she hold them upside down under her face resting her chin on them as to highlight her youthful look. "I'm known as the legal lolita."

I shame my head in disbelief then look around to see the rest of the crew merely nod and smile gleefully. I'm sooo embarrassed "Oh ooooh, damn... I'm so terribly sorry. I really though you were getting exploited... But now I can see you are not a little girl." That came out kind of wrong. However she seems to like it and just laughs even more. "Haha oh yeah you can see that." She once a gain push forward her chest inviting me to look at it and I do. But then stop my self taking a step back. Bow to her apologizing again, then I turn to the crew and does the same. "I'm sorry I will leave you to your work then. Please I didn't mean to disrupt your work. If there is anything I can do to make it up please tell me." It's an open question to everyone and all in the crew merely shake their heads probably just wants me out the way. But it's then the young looking woman says "Well, if you want to you can by me a treat after we're done. I'd like to know where such gentle men come form."

I can't believe what I heard. Did she basically **** me on a date with her? Yes, I think so, or at least that how it would be in any other country but this is Japan. It might be different here. I politely accepts and steps out the way, so they can continue. She is looking at me all the way smiling so cheerfully. Only to get reminded of what she was doing. I'm I gonna stand here and watch her do all this seductive poses? I guess so...
