I... don't even really care what was in the doujinshi itself. I mean, it was pretty good (visually I mean, as I can't read a lick of Japanese), but the title... my god the title is amazing. I'm just here because of the title. Specifically, the last part.
Yes, I did just copy-paste my own comment from the recently (as of 02/06/15) expunged version of this, why do you ask?
Edit: The title. Which in English was translated as "Once you've beg the girl you can not refuse、I was able to sex."
