Gabriel doesn't need much in the way of encouragement, chasing each quick pulse of Sam's hips as he gets that much closer to his peak. His eyes shift completely gold and he cried out raggedly, spilling over Sam's hand as he came so hard his entire world went warm and white. He's never been knotted before, everything in his body heaving with the force of his peak before he fell limp and boneless beneath his Alpha. His Sam.

"S-Sam." A miracle he can even form words after that. "Come Sam. Want you filling me up," he panted, pushing back against him.
