Takara's got high school life made. He has a cute girlfriend, and he's got his nerdy but good friend, Saku. Unfortunately, there's just one tiny problem...

He can't get it up when he and his girlfriend try to do it!!!!!

All his other friends aren't helpful at all. Takara feels like he has no one to turn to for advice... until he realizes that Saku may know more than he seems to... At first, it was just the two of them "practicing," but then, one thing leads to another...
