The dungeon room was dimly lit by a fireplace and the occasional cracking of the burning wood was the only sound heard in the space. Ebony bookshelves overspilling with worn tomes in muted colours lined most of the room's walls and a hazel leather sette with a black dress robe draped neatly over it's back sat opposite the imposing mahagony granite fireplace. In between lay a velvet green rug.
On this rug, a man kneeled uncomfortably, his wrists tied behind his back by harsh ropes and attached to the same ropes encircling his ankles. Mouth held open by a ball gag strapped harshly between his teeth, he was unable to form words and helpless to stop himself from drooling all over the high collar of his otherwise immaculate white dress shirt. His raven locks were damp with the strain of being held in such an uncomfortable position for what felt like hours.
The loud bang of a wooden door hitting a stone wall with force shook the man, one Severus Snape, who after his recovery one again took on the position of Potions Professor of Hogwarts School of Witchcraft and Wizardry, out of the daze he found himself after his forced stillness. He tensed and tried to move but was stopped short by the tight ropes he had almost forgotten as his tormentor closed the door and went to stand in front of him.
The red Auror robes Potter was wearing were singed at the ends and smelled of smoke and spellfire.
"Well, this took longer than I expected. I would apologise, but you know I don't mean it anyways. It's nice to see that you stayed put while I was gone but you seem a bit bored. For the next time, I may have to use something to keep you occupied. " Potter said, his arrogant smirk only widening when Severus growled at him.
The unexpected sting in his cheek announced the slap before he even heard it and Severus fought to keep the whine that tried to spill out, in. He would not give in, not yet.
Severus did let out a small groan of discomfort as the ball in his mouth changed into a cold metal ring by a silent swish of the Auror's wand. He futilely pushed his tounge against the ring to force it out but the only thing he accomplished was to further soak the front of his shirt.
Potter then took Severus chin in a bruising grip and tilted it upwards, the older man glaring at the younger all the while. Slowly, Potter lifted his other hand and inserted one calloused finger into the opened mouth before him, lightly stroking his tongue, not yet applying any pressure.
Severus tasted soot and dirt but faster than he could comprehend, two more fingers followed the first one and began violently moving in and out of his mouth. He gagged and tried to pull away but the death grip on his chin prevented him from doing so, leaving him to endure the torment.
He felt his eyes water and his breath stutter as the fingers mercilessly punged into his throat, making it hard even breathe, let alone swallow to alliviate some of the discomfort.
After what felt like an eternity but couldn't have been more than a few minutes, the fingers finally left his mouth. Severus was left feeling unsettled while tears streamed down his cheeks, dazedly trying to find his bearings and breath while drooling all over his front. Eventually, a dark chuckle caught his attention as Potter stepped between his spread thighs and bent over. The older man felt Potter's breath against his ear as he spoke and it made shivers run down his spine.
"It seems you liked that very much, pet." Potter purred against his ear as he tore off the first buttons of Severus' high collar. A boot came to rest against the erection straining his trousers while warm lips nibbled at the scars on the side of his neck, and Severus could not suppress the whine this time, his mind starting to feel foggy.
"Let's see if I can make you come just from rubbing my filthy boot into your cock." Severus heard through the fog of his arousal and ground down almost automatically, letting out a loud moan, his desire to hold back completely gone.
While Severus was moving mindlessly to archieve his orgasm, the younger man undid his belt and pants, freeing his own half-hard member and stroking it a few times to reach full hardness. With the display in front of him, it didn't take him long before he had precum beading at the tip.
Potter did not hesitate to use the warm, wet hole in front of him. With one hand, he grabbed the Professor's long hair in a painful grip, with the other, he held his member to insert it in one single push into the more or less willing mouth before him.
Severus twitched in his pants at the repeated violation of his mouth and throat and swallowed convulsively against the intrusion. This seemed to push Potter over the edge and with one last thrust he emptied himself into the body below him. Simultaneously, he pushed the tip of his boot against the older man's still clothed erection.
As soon as Severus felt Potter pulling out of his mouth as well as the increased pressure on his erection, he too came violently. Then, he slumped himself and didn't even notice the arms catching him as everything fell dark.

Severus regained consciousness laying on the soft silken sheets of his own bedroom, clad in a fresh pair of comfortable pyjamas and smelling the faint scent of his own brew of bruising creme. His wrists, ankles and cheek still stinged faintly but he knew they had been treated and checked for any lasting injuries.
"Back with me, love?" He heard his partner's soft question and he opened his eyes to see Harry sitting next to him on the bed, holding out a glass of water for him to sip from.
"Yes, thank you." He answered hoarsely and let a few more swallows of the cold water sooth his raspy throat. At Harry's concerned look he reassured him.
"I'm fine, just a bit of a sore throat. Come join me." Harry obeyed after setting the now empty glass and his glasses on the nightstand and slipped under the covers next to his partner.
"I'm really sorry about leaving you alone for so long and had the monitoring charm I had on you showed any signs of distress, I would have come to you immediately." Harry murmured softly against the strong chest he settled his head on.
"I know love, I always feel safe with you," Severus answered sleepily." As he drifted off, he heard the the tender voice of his husband whisper "I love you" and fell asleep with a slight smile on his face, safe in the arms of his husband and finally content.
