This is a trailer or pilot/pitch for a hentai anime that seemed like it would never be produced. At 3:15 you see the image above and the consequence of it. I figured it was nothing (just a sensual kiss into sex) given the lack of context and with no "real" anime to provide context I didn't think it was worth sharing. HOWEVER, a "real" anime is being produced and is going to be released in a little over 3 weeks. Check out the website for the anime here. That's great news by itself, but I couldn't help but notice the girl in the picture above wasn't in any of the trailers nor the promotional pictures. It's possible she's being saved for a next episode but even then who knows when or if that will come out...
So in short: Be on the look out around December 8th for a hentai that may or may not have a magic kiss but will be worth watching either way.
Interesting, I like how she's kinda summoned from the mask, and of course, yuri kissing, it looks like she gives up resisting halfway through and gives herself to it. *watches the whole clip* Ah... of course...
