>>2847042IMO Eiken puts every other ecchi/fanservice anime/manga and even a lot of hentai to shame in terms of pure sex appeal and fappability once you've seen it. There's a reason I can't get over it and keep coming back to it time and time again after all these years. I'm glad I'm not the only one.
But as far as good tit shows from the time goes, Mouse anyone? Along with Komoe, I always loved Yayoi. Something about those big round glasses combined with big round boobies just drives me nuts.
