When i see attractive woman's fingers i think about toilet paper?

There is a girl at work who I have feelings for, she is around 23 and works in the accounting and human resources department while I am in IT. So I don't see her often but whenever I am fortunate to catch a glimpse of her it brightens up my whole day. The other day she was showing off her newly painted finger nails to a female colleague, and I just happened to be passing by on my way to the coffee machine. She didn't seem to notice me at all, as usual. But then the strangest thought entered my head. Her nails were so pretty that I simply could not help but imagine her fingers touching some toilet paper that she could have wiped with. The idea turned me on like crazy. She is young, blonde, and beautiful, and imagining her using the restroom for basic biological functions, on top of her touching "unfeminine" things wth her super sexy delicate fingers made me so wild with desire.
