As kids Dean and Cas play and roughhouse together. One day as they're wrestling Cas accidentally rubs up against Dean, who responds in kind. They both end up rutting in a field. After, Dean runs away, thinking he took advantage of Cas. Years pass and now Cas is seventeen and an omega. Passing through the woods he finds Dean, now full grown as an Alpha. Cas says he always wanted him too. Dean, relieved, ravishes him against a tree, finally sinking his knot in his wet omega mate.
