In Severus Snape's not so humble opinion, the Muggle world had most definitely gotten quite a few things right.
For one they had quite a lot of alcohol, far more to choose from than the Wizarding World. Firewhisky does tend to get old after a while you know.
He also secretly felt that their use of electricity was quite ingenious. However don't you dare tell any one he said so.
But above all, the most exciting thing to come from the Muggle world would have to be one Hermione Jean Granger. There was just something about her that intrigued him.
Maybe it was the way her hair always had that "just-shagged" look, or perhaps it was the way those damned Muggle jeans clung to her round arse. Then again it was probably the way those low-cut T-shirts perfectly framed her breasts.
No, no it was definitely the way you could see the hint of a tattoo between the hem of her shirt and the waist of her jeans whenever she would reach to grab a book off the top shelf. A small peek at something very few people knew was even there.
Yes, it was definitely the dark contrast of the black ink against her creamy skin and the way the bold lines outlined the curve of her arse. He loved the feel of rebellion in that one image forever inked on her skin. It practically screamed, "I've been naughty and I need to be punished!"
The longer Severus stared at her tattoo the more certain he became the she did in fact need to be punished. After all, nice witches just didn't do things like that.
Severus decided that Miss Granger deserved a very special detention indeed. He'd show her just how naughty she could be.
