I've been searching for this manga like forever where there are these two high school(I think it's high school, but definitely a school with uniforms I think). And one of them always gives blow jobs to the other and acts all cool while he's actually not that cool while he's narating. And when the other guy wants to touch him too he doesn't let him, saying some excuse. But actually he doesn't let him because he's afraid he'll come immediately and that wouldn't be that cool.
Please help.
