While it's an complete understatement to say "Do not replicate" because it's just a manga,these people aren't real, etc... I thoroughly enjoy the responses people have from scenes like this. Stories really ignite something in people and that means the author has done their job. Enjoy that feeling :).
That being said, oh yeah... in manga world she would have had to crap out a toenail with how far my foot would have gone up her behind. Not. Cool. At. All.
