This review is as serious as the manga......
Surfing the net in the middle of the night can be quite fruitful, where you might stumble on some rare gems, weird stuff and other shit like this manga
Osananajimi no Mune ga Ookiku Natta no wa Ore no Sei kamo Shirenai, is a simple story told in a one-shot format....................
Basically theres this high school girl except shes got huge boobs. i mean some serious honkers. a real set of badonkers. packin some dobonhonkeros. massive dohoonkabhankoloos. big old tonhongerekoogers.
