I present a visual essay on why Miku is trash and Nino is best girl. Topics include the gradual decline of the Tokugawa shogunate, as well as the economic benefits of sticking small men into schoolgirl butts.
So got curious and translated some of the last frame of the anal scene, page 115.
It says something to the extent of her asking him if he ejaculated inside her and he replied he didn't intend to. She then goes on to call him a hopeless pervert and says:
"If you really want to cum so bad you can cum as much as you want inside my ass. Or better yet how about living in my ass? *giggle*" And he kind of lets out a cowardly yelp in reply.
