My Japanese Girlfriend and I

So, one day we were fooling around, and when I took off her shirt and jeans, she had on the kind of childish underwear that you would only find in anime--they were white with pink lace all over and a cute bow on the front of the panties and one in between the cups on her bra.  I didn't think much of it when she said "子供っぽいでしょ？" and we continued doing our thing from there.  A few weeks later, today, we were talking about the black underwear that she was wearing today, and how that's my favorite color as far as underwear goes.  She then mentioned the childish underwear from before and told me that she bought it just for me because she knew I was into anime and wanted to see if that was the kind of underwear I like on a girl.  I simply said "その子供っぽいのは嫌いじゃない."  I couldn't tell her that I'm actually a member of the greatest pedophile organization on the planet: 4chan!

>Should I ask her to put on her high school uniform and "rape" her?
Yes, I'm sure she'd love it. She's obviously fantasized about that since she was in middle school like every other good little japanese girl.

she's been out of high school for about 13 years
Wait, she's 30 years old?!
