Comments
I could only find the first two chapters of the manga online, and there is only a trailer of the upcoming anime adaption of the series.
The series doesn't look like it will have lots of fanservice, so this might be the only ENF scene in the series.

For those more interested in the series,

awesome posts sporzem. Many of them had a micro fetish of mine -- the shot from between the legs of a naked girl, with onlookers in the background of the picture...

Time to contribute. Good old Champion Retsu. Some ENF, and what may be the polar opposite of ENF.
