So, uh I wrote a polyamorous omegaverse threesome PWP fic:
Unconventional Bond – When John and Sherlock invited Greg over to share Sherlock’s heat, he didn’t expect things to go like this. But he couldn’t be happier.

Greg couldn’t help but feel nervous as he mounted the stairs. They’d discussed this, the three of them. John knew that he used to sometimes serve Sherlock’s heats. They knew that Greg was attracted to Alphas and Omegas. None of them were bonded, though Greg figured it was only a matter of time before they did.
Two alphas with an omega in heat could be dangerous; none of them minded.
Before he even pushed open the door he could smell Sherlock. He licked his lips and stepped inside. John was in the front room, clearly waiting for him. He could hear Sherlock in the bedroom, moaning already.
John met Greg’s eyes. There was a moment of frisson as the alphas faced each other. Then Greg crossed the room, leaned down and kissed John. Kissing him back, the smaller alpha took control, growling as he squeezed his hips. Their scents mingled and Greg relaxed himself, willing to submit.
Greg opened his mouth to John and slipped to his knees. John ran his fingers through his hair and pulled his head back, leaning down to scent his neck. Already Greg was hard. How long had he imagined this, being dominated by a fellow alpha? And this was John. God, he was a lucky man tonight.
Sherlock stepped out from the hall, naked and frowning. “There is an omega in heat over here, if you two are done locking horns.”
