Okay, well maybe it's because the movie came out months before I touched the manga...
While my knee jerk reaction is to blame Gia for exposing me to this highly intense, borderline erotic coming of age story, but I really, really enjoy it. So much so that I force Gia to buy the volumes then steal them from her. We've talked about it on PTS before, but Sundome is a manga by Kazuto Okada. The plot focuses on a fifteen year old boy whose world is rocked (but not literally,) by the appearance of an S&M angel (but not literally.) All of the sudden Hideo becomes the slave to the sweet Kurumi. Enthralled by female acknowledgment, but spurned by his sexual frustration, the story is oddly... fascinating.
Video after the jump. Which you should watch. Its not entirely NSFW, but people might ask you questions. Watch it anyway!
