ARM-606 The ultimate! A flirtatious dick! He's a silent M-man who can't say no, so I ended up doing something good for him!

A masochistic man who is silent and has a passive life, unable to assert himself at all. With a man like that, you would think he would not be popular with women... but no, that's not the case! Women who cannot read his feelings because he is too silent end up running around aimlessly and providing "extremely erotic" service themselves! A harem of women who are popular with women suddenly appears for this passive masochistic man! Is heaven or hell waiting for him as he is taken by them one after another...?
