RCT-677 - The world where spreading is the daily norm

Just like the title says, it's 'An erotic world purely focused on the 'manguri-gaeshi' (flipping) that fulfills every man's fantasy!'... I get the concept, but it needs a little more flair!

I thought this was a really innovative work. Focusing the entire film on the 'manguri' (legs-behind-head) position was a brilliant idea. Muto Tsugumi, the third girl, was perfect in her OL role! The masochistic elements like the squirt in that position and the foreign object insertion with a pen were also great. I want to see a sequel to this series. Highly recommended for those who love leg-spreading and manguri positions!
