I need a little help finding a series.

[IJustMadeThisToComment]

I forgot it's name but I remember some parts of it. (My memory of it is kinda fuzzy so forgive me for that.)
It was like a dude & his club mates suddenly have a girl member.
I don't remember much,but I do remember this part,the girl told the guy to "Shove a stick in his dickhole."
I remember cringing at that part,but now i'm curious to see where the series went from there.

bump.

I don't know this manga but I want to read it
