Sherlock AU
"You know John, if Sherlock had not gone into heat at the pool area, I probably would have killed you both. But considering the circumstances, I am glad you convinced me otherwise." Moriarty said with a smirk.
Both Alpha men stared at the bed in the middle of the back wall of the room. Sherlock was stretched out on the bed, his hands tied to the the bed posts.
There was a secret Sherlock kept from everyone he knew, even John. Sherlock was an omega. He regularly took Heat suppressing pills, but with the Moriarty fiasco he had been slipping on his doses.
Sherlock writhed on the bed, feeling the burning gaze of the two alphas. He clenched his teeth together, refusing to beg the two to fuck him. His body may be completely out of his control right now, but his mind was still functioning by at least 25%.
"God the smell of him," Moriarty groaned, "What are we standing around waiting for Johnny? Our omega needs us!" Moriarty was quickly removing his expensive suit and tie.
John, still a little stunned by everything that was Sherlock in Heat, as well as the other events of the night, nodded slowly. He took his clothes off, never taking his eyes off Sherlock.
Moriarty was the first to reach Sherlock, grabbing a fistful of his dark curls and shoving his nose in Sherlock neck. He mouthed at the skin there, leaving bites and kisses as he took in Sherlock's scent. John followed shortly after, wrapping a hand around Sherlock's chin to smash their lips together.
Sherlock groaned and writhed, trying to press as much skin against the two alphas as possible. He needed a knot. And soon.
"Our poor impatient knotslut. Whatever shall we do with him Johnny boy?" Moriarty said, kissing and nipping his way down Sherlock's chest. He stopped at Sherlock's nipples, pinching and twisting them.
"Would your breasts swell if we bred you? Would these little pebbles pump out milk? We'd like that wouldn't we John? We'd milk him dry, just like he'd milk our knots."
Sherlock cried out at Moriarty's words and administrations, and John groaned at the thought of Sherlock swollen with his child.
John slipped a hand behind Sherlock, pressing two fingers against his back entrance. The fingers easily pressed inside, as wet as Sherlock already was. John pumped his fingers in and out a few times, bending them to press against Sherlock's inner walls. As John added another finger, Moriarty was still playing with Sherlock's nipples, sucking, licking, and biting the now red and erect areolas.
Sherlock was mewling, arching his chest into Moriarty's mouth while fucking down onto John's fingers. He could feel an orgasm fastly approaching. Once John added a fourth finger, Sherlock knew it was over. Moriarty wrapped his hand around Sherlock's neglected member, stroking it once, twice, three times, and Sherlock was coming violently, crying out a weird mixture of the two alpha's names.
John removed his fingers as Sherlock's body went limp, his mind a little more clear from the heat. John looked at Moriarty, who was licking his hand clean of Sherlock's cum. Moriarty raised an eyebrow, before smirking. "Sherlock dear, how do you feel about taking two knots?"
Sherlock's head fell back with a groan. This was going to be a memorable heat.
