One of the many things I appreciate about Raita is that a good chunk of their stories feature double penetration as I'm a big DP fan. I just wish we had a 'double penetration' tag though.
Certainly an interesting title.
Well...I suppose the fact that they are a Kappa and a Fox Spirit makes it easier for her to believe it's a dream.
I must say though, I really do love that ending! Heh, not exactly what I expected to happen, but I'm certainly glad it did. Too bad we didn't get to see them...Join in on the fun as well, but hey, it's still a great ending.
