[Sexual content + warnings]
The third boy is slender and dark haired. He's willing to put up with all your idiosyncrasies, with the fact that you don't want him to touch you at all.
You think he might be a little insane, what with the way that he follows you around like a puppy, but he's smart and he's useful. On the few times you ever allow him close, it's always when you are both dressed, he's not allowed to touch you otherwise. Never on your bare skin and never while he's on top.
He's willing to do anything you ask, but when he asks for something, you find it a little strange. Choking? You can choke him, you're sure of it. With or without the sex. So you agree and when you're in bed, legs bare, panties still on but pulled to the side so he's in you, it's all too easy to wrap one pale hand around his throat and squeeze.
His face goes rapturous, his body taught as you cut off his air. It's almost scary and you let go, only to hear him plea, nearly demand, "Again." So you do it again, and again, the power of death in your hands. It's the first time you ever orgasm, listening to him struggle for breath and he comes so hard he blacks out. When he comes to, you're smirking, the thing inside you born and hungry for more.
