The two of them had ample opportunity to put an end to this. To think about everything that they risked by even letting this be more than a fleeting thought but they didn't. Given the fact that clothing was being removed now it was all a little too late. Loki moved just enough to remove his own before moving right back towards the other.
"I'll avoid it." He promised, honestly promised, between sucked in breaths and soft noises as Bucky continued to press kisses to his neck. There was plenty of other skin to explore, another shoulder to grip. He really paid no thought to the hand allowing Bucky to use it if he wanted or to avoid it as much as he could. Loki ran fingers along the other's back, careful not to scratch or leave any discernible marks. He had no one to go home to, no one to hide from so Bucky was free to leave marks and bruises. Loki was more than aware he didn't have the same luxury.
