Benjamin had to break the kiss off at that, because he'd meant for them to move, yes, but he hadn't expected quite that, didn't know what he had been expecting anymore, not when all the blood in his body was heading south. The way John moved against him was the most erotic experience he had ever had, and they still had all their clothes on. In fact, he was even still in his coat, sweating, turned on, and not exactly going to last very long, not after so long. He squeezed John's arse and moved with him, hips rocking slowly, adding to the slow, beautiful friction and breathing short and hot against John's skin.
