Made Omega (слэш)

For a prompt at the avengerkink meme:
"Clint was born a beta and has been perfectly okay with it. Then he gets taken by Loki, who turns Clint's biology inside out and makes him a full omega, planning to make use of it once Earth is his.
Of course that fails, and he's sent back to Asgard. Then Clint goes into his very first heat. I want full-on, serious heat, so wet he's leaking through his trousers, aching and nearly incoherent with need. And it's even more overwhelming for him never having experienced it before, since most omegas have minor ones when they're in puberty.
So he's dealing with the sudden massive change in his instincts and the way his body reacts to the pheromones of those around him. As I'm particularly partial to watersportsloving!incontinent!Clint, I want him to wet himself as a submissive gesture when his Alpha does knot him. The Alpha expects it, but Clint doesn't.
+1 for another omega on the team giving him a pep talk on how to handle everything. Would love if this was Tony
+10 for a knotting dildo being mentioned or used at some point
+the WORLD for lingering on just how long they're locked together after and how much Clint unexpectedly loves it."
