Loki silently complied with the removal of his top with Eric removing it and then Eric removing his own. To see Eric chest exposed, the Jotun saw a sound that was healing, a sound that he remembered from when Eric saved in the Dark Forest the first day they met. Loki also saw how for the man was and smiled compared to himself who wasn't as for as the man before him but he at least wasn't a twig. As fit as he what ever gotten, Loki had the forest that he ran through. Though he had wings once upon a time. But no matter how much sun he was exposed to, his skin stayed it's pale color. 

Being turned around, Loki turned around till he was stopped to feel Eric's chest on his on his back, feeling just how warm the man was. Yes Loki was slightly warm bit could feel a chill to him that was proof of his heritage. Loki allowed what access Eric needed for his neck, feeling the kisses he was planting. He moved his hand behind him and Eric till they were wrapped around him the best he could. He didn't mind.
