Where did he hurt... it felt like everywhere, at the moment, nerve endings laid raw by the force of Jim's attentions to him, eyes like fire on Matthias's bared body. The careful, masterful way that Jim had coaxed his lips to part and let him within had ached, too, a deeper ache that he reveled in. Nothing about their love was comfortable, was it? If it was comfortable, Matthias didn't think it would have been worth having. Jim had asked for a place, though, a certain place that he could make all better. It was tempting, to direct him to Matthias's swelling cock underneath the fabric of his underwear, to see if Jim would take him in his mouth and ease him that way, but Matthias had no desire for the game to be over that quickly.
Instead, he raised a hand and pressed it over his heart, beating fiercely against his ribs like a caged animal. It had ached bitterly when Lucien had rejected him, refused his offer. Now, it ached with need, with all the feelings he had for Jim that not even poetry could express, for all that it (and he, in reciting verses to the man who hovered over him) tried. Oh, he knew, knew very well, that it wasn't his heart that felt, but his brain. It was still his chest that ached, ached with sorrow, ached with how desperately he needed the comfort that Jim was offering.
Another hesitation, and he raised it to his throat as well, tight with emotion, with words that had been torn from him as he'd tried to explain to Lucien, who hadn't been willing to listen. Not then. Perhaps not ever again unless Francis worked some sort of magic upon him. Jim's teeth there wouldn't do anything to ease the pain, but it would provide a new sort of pain. A sharper sort of pain. That was all, at the moment, he could ask for.
