One

        By the Angel, the words stained Will’s mind as he began to breathe faster, deeper. This sensation was not new to him, but with Jem, with his parabatai, the experience was completely foreign. In the instances before, it had been meaningless, pointless. But here, now, this, this was passion, this was important, this was momentous, this was real. Love. Will wondered, is this what it feels like? And as Jem continued vicariously running his hands over Will’s body, the silver-haired boy was thinking the same thing. His slim fingers felt their way to Will’s waist and gripped the hem of his trousers; then he paused, uncertain, but Will urged him on, kissing his neck and muttering under his breath, “It’s fine-please,”            

            And Jem obeyed, unbuttoning Will’s trousers and tugging them down his legs; it was about as graceful as falling down a flight of stairs (though if anyone could make that graceful it would be William Herondale), but soon they had slipped over his ankles and onto the floor, and there was nothing between the two Shadowhunters save both of their drawers. Will hands were now encircling Jem, holding him there, the nimble fingers of his left hand entwined in Jem’s silvery hair, and the other arm wrapped around Jem’s back, so that he gripped the left side of Jem’s abdomen, feeling the muscle move under his skin.

            Will moaned as Jem kissed his neck, and then it was no longer kissing, but sucking, lightly; Jem’s teeth would occasionally nip Will’s neck and Will was doing the same to Jem’s shoulder and then Will’s hands were at Jem’s drawers and he knew it was alright and then they were off and so were Will’s and there was nothing between them.

            Jem’s skin felt so good up against Will’s, smooth and clean and Jem. They were breathing together now, and each breath felt more and more like they were one, nothing could tear them apart. Will gazed once more into Jem’s shining eyes, knew he had permission, and he turned himself over, so he was lying on his stomach, Jem still on top of him and grinding against him, and then Jem paused for a moment. He reached down and turned Will’s head to face him.

            He whispered to Will, their lips so close, almost touching; he said, “I love you.”

            And Will said it back.
