Would this count as the first Touhou crossover with this character?

While most know it as a Touhou thing, it doesn't strictly originate from there, so it isn't.

ITs from a H-manga by Nitta Jun... Cant remember its name... but its something about two girls making fun of a boy being a virgin... saying its digusting... blah blah blah

Q-quiet you!
