Help finding porn comic series.

I read this series years ago that I've been meaning to get back to. I don't remember the name of the series or the author. I remember it was a fantasy series, the artstyle was somewhat similar to Oglaf, all the main characters were female, and there was a part were they had to infiltrate a monastery that only allowed men, so they had the flattest among them, a red haired girl, dress up as a man and join. One of the monks tries to have sex with her thinking she is a boy, only to discover she is a woman, but decides to go with it anyway. That's all can clearly remember, anyone know the name?
