Hand delivered the last component in a Hikaru Genji plan, and it succeeds because somehow she was too stupid to pass sex ed, as she didn't even know what sex was?
The good o'l "Hikaru Genji" school of training, eh?
On another note, "She's So Innocent, But Hardly What I'd Call Pure. My Naughty Little Stepsister Was Born. ★" could basically be an LN/manga/anime title in this day and age. :)
Damn, so many mixed feelings about this one. On one hand, the guy is such a manipulative bastard, but on the other hand, it has almost everything I could otherwise want from a chapter, and despite the weird road they took there, the future seems quite happy for the two. That, and at times I found myself wondering whether she truly was that naive or just played along with him in the end, especially considering that she should be old enough to know how these things work by now.
Wow they need to settle their relationship and we need a sequel cause we all know she pregers off that ending or its just hentai logic and she was just feeling sick
Tender, loving care indeed...
Really though, once you raise a girl to be that naive and trusting towards you, especially considering that ending...
Well, all that is really left is for you to commit to taking care of her forever so that no 'bad' guy can take advantage of her naivete. Basically marriage. I mean she's pretty much already pregnant, what with showing signs of morning sickness, so all that is left is to take responsibility.
