Trusting a Code Geass wiki, Kaname Ohgi and Villetta Nu (here, there) are married at the end of the series.
The present share must take place a long time before that (reminder: I’ve only known Code Geass through hentai and hasty wikis ^^), as Ohgi and Villetta live together but are still very awkward around each other, and aren’t lovers yet. Of course: “yet”, you’re reading hentai :3
How it begins: the girl asks the boy to scrub her body because she’s wounded and can’t take baths, he’s embarrassed but accepts, and the evident sign she was down to fuck is that she got naked, except that she kept her thighhighs.
No vanilla (but signs it’ll come eventually), it’s just sex afterwards. I must be frank, the drawings are mediocre, they’re amateurish and the woman’s body sometimes look weird.
But, hey, that’s part of the charm to me, that it wasn’t “pro”, it felt fresh. In itself, it was original and felt pleasant to read for this reason… (Not sure I’m making sense with you, sorry…)
In addition, the manga is written to make us sympathize with the male MC, it was a bit funny, that part also felt heart-warming ^^
