Sometimes Tracer couldn't manage it alone - it was getting colder, now, and the ground was harder than it should be, even here in his dark little cave of a basement. Sometimes he couldn't call up more than a few inches to sink down into, just enough to feel the edges of a real embrace of it. His brother touched him, though, fingers on the bare skin of his side and his back, and he knew he'd be able to sink in completely with him, if they wanted.
He waited, though, hands sliding up his brother's bare arms, over his shoulders, for a second just breathing in the warmth. Pure, organic connection. It was almost a novelty, lately.
