This may not be what you requested but I had some time to write something down. Oh boy I will get on my knees for Titus. Anyway this is a good sensual blood Angel!Male Reader (Bladeguard veteran) x Lieutenant Demetrian Titus.
CW: MR really has a hard time controlling his red Thirst, sexual implications or really just soul shattering devotion
Titus felt your canines against his teeth, long sharp, dangerous even for an Astartes. The air between the two was scorching like the skies of Baal. "Blood, fuck no...I need it..." saliva was pouring out your lower lips, strings of need coating the aching teeth.
You launched back at his mouth, you didn't meet resistance. His plated hands couldn't find a place to put themselves but then they found the back of your head. Hair dump with sweat and steam, warm and feverish.
"Punch me, I don't want to hurt you Demetrian!" His mouth was the only thing that bearly quenched your thirst. You fell on your knees hands on the dirty metal plaques of the floor of the Thunderhawk.
For a moment he evaluated the possibilities. His blue eyes, those damned blue eyes vultured apon your small figure, before it was a roaring source of doom for those Tyranids, before it was the one that shielded him from the swarms of xenos...now...it was small, a leaf caught up in a raging storm unable to find its way into a safe branch.
"No..I will not." Firm and stoic as ever but with a hint of uncertainty. "Take my blood, as much as you need" he extened his naked forearm and wrist. You looked at those blue orbs and then launched without second thought. This was not you.
Your composure faltered, your knees stabilized your weight to the ground and you fell on his back, you on top of him. Immediately one of your hands held brutally the meat.
That twisted part of you cooed at the site, that part of your brain screamed victory and savoured every inch of this new meal. Your mouth was nothing but an entanglement of strings of spit amd saliva, your tongue ran up his arm giving licks every noe and then trying to find the golden casing of that warm treasure.
You nipped and bite down not finding what you needed. "Fuck those primaris augmentations" you managed to whisper trembling. Titus's hand tried to reach for something near your face, maybe trying to wipe away those tears, but you slapped it and pinned his to the ground.
You sank brutally your teeth, the flesh was hard and do you bit down with more force. You heard a pained moan under your form, you looked down and Titus was looking away. In your foggy brain you recognized that you may have been too sudden.
"Sorry" you eased up the tension of your maw. "Don't be" he hushed. "I am a monster" small tears formed under your eyes. They say the Angel of Baal sheds tears whenever his sons are in pain, now he must be crying rivers.
"You are not." You began sucking on his wrist, irony smell hit your nostrils like a ram. You inhaled, you liked the wound you gulped down like a mad man. You bit down, you sucked and continued all over again.
"I want to tear your flesh apart, eat you until there is nothing left for you to save. I want to devour your soul, savour it, preen at the way it squirms in my hands." Blood was dripping down Titus's forearm. His eyes were shuddering, he was looking at you.
You exchanged looks as you continued to rob him of his red essence. Your gaze not as delirious as before.
The wound closed almost immediately, fuck those Primaris augmentations, amd you had to reopen them again four times before your innards were satisfied.
You let go of the hold of his forearm and now you could get a true understanding of the position you forced him to be. On top of him, right arm forced under your grip on his ground, your legs straddling his reinforced waist. Long moments of silence lingered.
Your breathing was the only thing that could be heard other than the engines. "You meant everything you said?" That was the first thing he said. Not "Get off me!" or "Get away"...
You hesitated, but you nodded, from one pouch of your belt you took a small cloth and dried up his sweat. You were going to get off him but he stopped you.
He gripped your wrists and yanked you down, mouth clashing in a rough and awful kiss. "You like this taste? It's awful"
You gulped down once you could talk again. "Your blood is different... it's sweet and far more enticing than the other things I drank".
