"Oh, scheiße... that's it."
You perked up at the way he rasped those words against the seam of your cunt, distracting you from the way you were aching for his fingers or cock, positively soaked and waiting for him to do something. Anything. You were always ravenously horny at this point in your cycle so this wasn't unusual for you, but his reaction despite still being fully clothed and literally just getting into bed with you was.
"You smell so good. I just -" you heard the clinking of his belt, felt his hands moving against your belly and thighs as he pushed inelegantly at his pants and boxers, "Fuck..." In a fit of possession, rough hands grabbed behind your knees, pressing them back to your chest and pushing the air from your lungs as he dove in straight at the source. He licked and sucked from your clit to your entrance like it was life-saving nectar, the sweetest ambrosia, filling his lungs with your scent as his nose bumped against you, the little hits of sensation lancing up your spine and making you squirm and arch against the bed.
"König, it just means I'm fertile." You said matter-of-factly, a throwaway comment as you stretched with an airy sigh, spreading your legs wider and dragging your nails gently over his neck and shoulders, wishing he'd just get to fucking you. He sat up and wiped your slick from his chin in a way that made your core twitch.
"Ach! I've been trying to figure it out for months." One thick digit pressed into your heat quickly followed by a second, causing you to gasp. You were so wet and so ready it felt like honey pooling in your slit, causing your bones to itch with anticipation.
"Will you let me fuck a baby into you?" He asked suddenly, seriously as his fingers kept on sawing into you, your hips churning slowly in counter. Had you heard him right? His eyes were glued to where his fingers plunged in and out, his other hand pressing down on his hard cock. He looked up at you pleadingly, withdrawing his hand only to place those sticky fingers in his mouth and suck, leaning fully over you.
"You will be so beautiful when you're full with my child, Y/N -" he said it like it hurt, a private confession pulled into the light to be judged. He pressed into you, heavy cock slipping finally through your sopping folds to repeatedly, blessedly bump against your neglected clit, "Bitte, mein liebling."
You had barely said yes before he'd made his first thrust, thick length parting your gummy walls as you threw your head back, hissing out a breath and clutching his shoulders as he rocked deeper and deeper into your aching clasp. He was desperately kissing you, all teeth and tongue as he licked into your mouth like he could steal your affirmation before you changed your mind. Honestly, your mind was pretty useless with the way he was groaning and fucking into you; each thrust deeper than the last, a jolt of pleasure pain on each ingress that burned out your senses and had you bearing down on his cock as you inched closer to your end.
"Touch yourself." Came his strained command, his rhythm faltering and pace slowing slightly as he breathed heavily through his nose, jaw tight as he reined himself back from the edge. Lazy thrusts lit up your belly as you quickly reached between your bodies to swirl your fingers over your clit, overcome with images of a pregnancy and your King with a babe in his arms, a babe with your hair and his eyes...
"m'close, so close, König... please..."
He all but whimpered against your neck, licking a hot stripe up the column to purr into your ear, "Give it to me, mein schatz." He picked up the pace, pressing into something devastating inside you that had you keening, twitching and pulsing around him as you hit your high, gasping into his mouth as he spent himself with a painful sounding groan. He thrust lazily a few more moments, drawing out the aftershocks and making sure his seed stayed where you both wanted it to be. He gently rested above you, holding his weight off of you as he began to soften; he studied you as you recovered, gentle puffs against your cheek and dark eyes set on your flushed face as he hoped you wouldn't regret this.
"You know..." you pressed a sweet kiss to the apple of his cheek, ruffling the damp hair at the nape of his neck, "it doesn't always take the first time."
"I guess we'll have to keep trying, ja?" He chuckled, clearly relieved as he withdrew from your body, drawing you close and lovingly pressing a hand over your belly where he hoped to take root and make his home.
