All that magic stored in him must have some healing properties. Cause that guy surely must have a sore dick from maintaining a constant erection. And I know he is being nice and all, but c'mon man do them when you are sane, at least you can enjoy yourself that way insteada being mindless.
Man, I'm always happy to see another chapter to this series, absolutely love it. I'd also love to see their reactions to the two other sisters coming in, and also considering their personalities, it seems like it'd be a really interesting reunion. That title really makes sense when you consider there are 4 sisters who essentially correspond to the 4 seasons, which is quite intriguing. A 3P with the two sisters sounds heavenly, but a 5P with all 4 sisters? Now that just sounds like paradise. Definitely can't wait for the next chapter! Also, if this series ever comes out as a book, definitely buying it.
Why do I get the feeling this is going to end up with the typical hentai harem ending of all four of them knocked up and in love with the protagonist's dick?
Given the tone and the way the girls were acting, I think that it's pretty clear that they'll actually be in love with him and not just his dick (especially Primula). Also, the first chapter did have a title page that said "The tale of a love for four sisters," and the chapters have been vanilla thus far. So, while I'd definitely expect a harem ending, it looks like it's going to be a vanilla, harem ending. It wouldn't surprise me if they all ended up living with him in our world, and it wouldn't surprise me if he ended up going to theirs, marrying them all, and becoming king (since they're princesses).
can't wait to see the other two in action!
