Work Text:
You were sitting in Sirius’ lap, both of you in only your underwear as the older man’s tongue vigorously explored your mouth. You weren’t dating each other per se - he wasn’t interested in that sort of thing - but you both often met up with each other for sex.
You pulled away from him, a string of saliva still connecting you both. “I want to try something.” You said after catching your breath.
“What is it?” Sirius asked.
“It’s a new position.” You turned around before getting on your knees, and you grabbed one of the pillows to put it under your chest. You then brought your ass up like a bitch in heat, and you peered over your shoulder to see Sirius’ face.
And you could tell that he loved it.
“Scheiße…” he swore under his breath, “don’t do this to me darling…”
“Why?” You asked innocently, despite very much knowing what this was doing to him.
He growled as he crawled over to you, and you felt as he pulled your panties down to your knees. He then put his fingers into your pussy, and you gasped when he started scissoring your cunt to loosen it up. You whimpered as Sirius dug his fingers deeper into your vagina, and he brought his thumb in to start rubbing your clit.
“So impatient…” Sirius muttered, but you could also tell that he wanted his cock inside you as soon as possible. He finally pulled his fingers out after he deemed you loose enough, and you felt him grabbing your waist as the tip of his penis pressed into your aching cunt.
He then harshly thrusted into you, and you gripped onto the edge of the pillow as his massive cock filled up your insides. It felt like it was going to split you open, and your position didn’t help much with it.
But despite that, you didn’t hate it. If anything it only felt better.
“Am I ok to move?” Sirius asked, as if this was the first time he’s been balls deep in you.
“Yes…” You gave him a roll of your hips, causing both of you to moan, and Sirius continued his harsh thrusting into your tight pussy. It was as if he was a wild animal in rut, and your legs quivered from having to hold up your body as he did so. The deflated knot at the base of his penis didn’t help matters, and you were hoping that it would inflate inside you at any given moment.
“Please… harder… I-I can take it…” You begged, and Sirius grunted as he picked up the pace. He leaned in closer to you, and you could feel his sweat glistened body pressing against yours.
“Du bist so schön,” he whispered in your ear, “taking me in so well~” Your back arched as he slammed his cock into your sweet spot, and your knuckles went white from how hard you were gripping the pillow.
You saw stars as you screamed in pleasure; he was probably going to rail you to a tear, but you couldn’t care less. He would absolutely destroy you and you would beg for it again, and he would give it to you every time.
“Please daddy,” you whined, your eyes filled with tears, “breed me~”
Sirius froze; if you could look back you’d probably see the Canis Major itself instead of him. “You want me to do what, darling?” He asked, but you could tell that he knew exactly what you were asking for.
“Breed me daddy~ Fill me with your-” You were cut off by Sirius thrusting into you, harder and rougher than he was before. Tears fell from your eyes, and they dripped down onto the pillow below you. All that you could do now was loudly moan and whimper Sirius’ name, any other words were now completely whipped from your vocabulary.
Then his knot expanded inside you, and you knew that there was no going back; not that either of you wanted to. You wanted to be knotted ever since you found out Sirius had it, but he’d always been so hesitant, worried about the possible consequences of it. Now you were being stretched beyond your limits, but you would be lying if you said you didn’t absolutely enjoy this.
You felt Sirius leaning onto your back again, when suddenly he bit into your shoulder. You gasped in pain and pleasure as his fangs pierced into your skin, pricking at the veins underneath and drawing blood. The bite was deep, as if Sirius was trying to claim you as his mate, and only his.
Sirius licked the blood and sweat on your shoulder, and he started rubbing his hands over your belly. “I’m going to cum now darling. I hope you’re ready to be the mother to my pups~”
“YES PLEASE~!” Just as your pussy tightened around his penis, he bit into your shoulder again, and he gave one final, harsh thrust before filling your insides with his cum. Your legs finally gave out, and you collapsed onto the mattress. Honesty, you’re surprised you managed to hold yourself up for so long.
You put your hands over your belly, which was filled with Sirius’ cock and his seed. You were too young for kids - especially with someone twice your age - but you could worry about that later. Sirius was also still knotted inside you, but by tomorrow morning it would probably be loose enough for him to pull out.
You heard Sirius purring as he laid on top of you, and he nuzzled into your neck as he made you both comfortable. “Gute Nacht, mein Schatz.”
