The ripping sensation wasn't the most pleasant but what followed made it worthwhile. Tony's head lifted from his arm and he closed his eyes, brows knitting and lifting in rhythmic motions. He would have to hurt himself more--

The thought made him groan, and not quite in pleasure. Tony was a risk taker, he didn't always follow safety measures, but he wasn't thinking of Steve as the ultimate band-aid. It simply felt so. Good. So fucking good.

He let out a heated breath and curled and uncurled his toes. One would think Steve was doing more than licking up trickling blood.
