Fill Part 6

[tsukichibi]

Sherlock had sensed that there was something different going on from the second that the class started. At first he couldn’t put his finger on it, but a few minutes of prowling around had easily allowed him to identify the issue. Namely, one John Watson, who was apparently presenting as an omega but had no idea judging by the fact that he had come to a school that was filled with nothing but betas and alphas, neither of which could be counted upon to control themselves around a fresh young omega that was entering his first heat. Or at least, Sherlock hoped the boy had no idea, because other he was even stupider than the rest of the students.

In less than five minutes he had the room cleared. He could see the realization dawning as a handful of them, the most astute of the lot, left the room, but he had the door shut and locked before anyone could really react. John was bent over his desk and, in all honesty, looked truly pitiful. Sherlock meant to get him out of the school safely but somehow he found himself cupping John’s cheek, his thumb tracing the edge of the boy’s cheekbone while John watched him with enormous eyes, pupils blown wide from the effect of his arousal, a pretty pink blush painted across his cheeks, lips parted slightly. Sherlock slipped his thumb down and traced John’s bottom lip. A small pink tongue came out to touch the tip of his thumb and he growled. John whimpered in response, lips closing around Sherlock’s thumb and suckling gently.

Shit. Sherlock shook his head briskly and pulled his thumb away from the warm, wet heat, realizing that he was succumbing to the effects of the heat himself. The temptation to strip them both naked, to taste John in every sense in the word, was overwhelming. He wanted to kiss John, to wrap his fingers around John’s cock, to part his arse cheeks and taste his core before burying himself deeply into that heat and fucking John until the boy knew who he belonged to, until everyone knew that John Watson belonged to Sherlock Holmes.

“John,” he rasped, forcing his hand back from John’s face. “I think you should leave. Through the window, now. I’ll call you a car that can take you home.” Mycroft would be watching, as always, and he would have the resources to make sure John got home safely. Sherlock hated depending on his brother but in this case he would make an exception.

“I don’t want to go,” John said. His blue eyes had taken on a hazy quality. “You smell so good, Professor.”

“That would be the hormones. My body is responding to your proximity and producing more of my scent to entice you,” Sherlock replied. Evidently it was working. “It’s simple chemistry.”

“I like chemistry.” John stood up, and although his legs shook underneath his weight he managed to stay on his feet. Slowly, he came around the end of the table. Sherlock had to bite back another deep growl when John’s scent struck him even more strongly than before. John’s trousers, he noted, were drenched with fluid. His mouth watered.

“John, you should leave. Now!” With effort, he looked away and moved quickly across the room. He’d left his phone on the desk, he knew. It would only take a few seconds to contact Mycroft...

That turned out to be seconds he didn’t have. John moaned and he had to, he just had to turn and see the reason why. What he saw froze him on the spot. John was standing where Sherlock had left him, his shirt now fully unbuttoned. Even as Sherlock watched, John pulled the shirt off and let it fall to the floor. He was breathing hard, his chest heaving, as he started unfastening his belt. He thumbed his trousers open and let them slide from his hips with a low, strangled sound. He looked up and stared straight into Sherlock’s eyes as he slipped his boxers down his legs, leaving him standing completely naked in the middle of the room.

“Please,” he said. “It hurts, Professor. Can’t you make it stop?”
