They did in the chapter 16.5 of volume 1 of the LN, this chapter is omitted from the story cos' well we all know being 'it' it's so damn inapprpriate.

Also, this has only been done in-game, Reki didn't specify they did it or not in the real world. Tho I really hope they do sometime. If you're gonna ask how, it's all explained in the chapter itself. 'Bout the Ethics code and all. It's still only a game.

Ok ok, not gonna spoil any further. Keep calm all Kirisuna shippers, they hopefully, as read in another Q&A post, will get married and maybe have children. Well at least have a stable relationship. And hopefully this will tame down the ocean of non-stop questions. ;)
