A/N Something that popped into my head.
"En garde" Harry shouted, as he waved a silver sword through the air
Severus dutifully ignored his sword wielding husband and continued to organise student essays into their respective piles.
"I demand you gather your sword sir" Harry commanded, lunging forward and poking the tip of the sword into Severus' side "lest thy wishes to be run through"
Severus took a deep breath and inwardly cursed Minerva for the thousandth time. The infernal woman had seen fit to organise a medieval tournament at Hogwarts, where students would have the opportunity to participate in various activities based around medieval times. (with a large focus on the Knights of the Round Table and Merlin)
The Potions Master had refused to have any part in the proceedings, while his over eager husband leapt at the opportunity to be involved. Hence why he was being subjected to his husbands childlike antics.
Harry had taken every chance he was afforded to immerse himself in the culture of the age, from wearing the traditional Knights outfit (Chainmail included) he'd created his own shield and gone as far as to redecorate their quarters befitting that of a Knights chambers.
"I command thee Sir" Harry instructed again "take thy sword and face me"
Severus growled low in this throat when he felt the tip of Harry's sword poke his side. His patience was hanging by a mere thread and would snap at any moment.
"Is thee a coward Sir Severus?" Harry challenged, green eyes alight with determination
It was the word coward that snapped his resolve. In one fluid motion Severus rose from his seat, picked up the sword and was standing toe to toe with his husband, who had the audacity to smirk at him. Harry had little to time to react before he was fending off Severus' sword coming dangerously close to his own.
Metal clanked and echoed throughout the room as their weapons connected with each lunge and swing. Severus was as fierce a swordsmen as he was a duellist, Harry's couldn't deny the heat coursing through his body at the display of strength from his husband.
Severus took advantage of the hungry look in Harry's eyes and moved with stealth and precision, slashing his sword across the front of Harry's chainmail.
The Professor gave a squeak of surprise and adjusted his stance, giving a slight shake of his head as if to realign his focus. It wasn't enough, in a split second Severus had lunged forward and pinned Harry to the cool stone wall, sword pressing against his throat.
"Does thee think me a coward now Sir Harry?" Severus asked his voice a low rumble
"On the contrary Sir Severus" Harry replied hoarsely "I consider thee to be a fine swordsman. A finer display of power I've not seen"
"I'll give you a display of power you insolent brat" Severus growled, dropping the sword and plundering Harry's mouth in a hard kiss. Pulling Harry flush against him, he ground his erection into Harry's thigh, delighted at the whimper escaping from the man's throat.
"Will thou demonstrate the extent of this power?" Harry said breathlessly, when they pulled apart.
Severus' response was to collect Harry in his arms, walk quickly to their room and deposit his husband unceremoniously on the bed.
