Just saw the episode, pretty good imo. I've been wanting to see this since the release of the PV back a couple months ago.
The animation is rather good even though you can tell that some parts of the animation are looped, but its a hentai what else would you expect :)
The voice acting done by the female lead is good and enjoyable. The thumbnail used to promote the hentai is a bit misleading in the wrong direction, but maybe might be animated in a future episode.
Lastly, I love how innocent both characters are throughout the episode up until the end. Very wholesome.
Overall, a pretty good watch and hope to see more episodes in the future.
