There's no way to be sure without facial features, but I'm pretty certain this is Tomomi from the Kao No Nai Tsuki anime.

din din din, you got it! she is tomoni-chan

Too bad this show doesn't show too much money-shots or cute male leads like that blue-haired guy. :(

I liked her way better than the main girl.

its moonlight lady

Tomomi rules, she turns me so ON!

Lazy animator doesn't know how to draw even breasts. It's like one's plastic and the other one's real. lolz XD
