There's strength and power in Gabriel as well. Sam can feel it thrumming through his Omega's body. He kept thrusting, pushing into Gabriel's body, making him work to accept his knot. Somehow, this coupling seemed faster, harder than the first. Maybe because Sam wasn't holding back as much.

As soon as he felt his knot push all the way in, felt Gabriel's body accepting it and closing around it, he bit, teeth breaking skin as he growled deep in his chest.
