Nice picture! Is this character from a series or just an original?

She is a character from an eroge game called Hoshiuta. Her name is Kurara Amamiya.

I must say...I'm used to black pantyhose ( you can kinda see the panties) but not white. Anyway this is a good position with her expression.

Yeah, I prefer black too, especially if there's a black circle around the thigh on each leg. however, white pantyhose reveals a "pure" image, it's moe.
