Sherlock decides to take control, since John obviously isn't suited.

Love is a disadvantage. At least that's what Sherlock's older brother Mycroft has always told him. Sherlock tries his damnedest not to love John. But he can't help just needing John. All. The. Time. John has always felt that way, and tries so hard to hide it. Sherlock's perfect angel carved cheekbones, his charcoal black curls, his seductive lanky body structure, and it's not just his looks, it's how he talks, how mysterious and sensitive he is, just everything about him drives John wild. Both men start to find it very hard to hold it in, but neither succeed.
