TRIGGER WARNING! Bloodplay/knifeplay. Body fluids
From beneath Natasha she felt, rather than heard, the moan reverberate through Loki's chest, making the blade slip slightly from its trail down his side. Blood beaded at the opening, coating the dagger and mixing with the other cuts she'd made earlier, some of which were already healing. That wasn't any good. With her teeth sinking into her bottom lip she grinned down to him and leaned over to kiss the cuts she'd made, coating her lips with his blood before she forced her lips onto his. Again another moan, and this time he jerked his hips up to sink himself further into her. She shivered, coming away sticky and coated in red and licking her lips, the rich copper taste filling her mouth. His eyes were alight when she finally locked gazes, and again he thrust up into her, making her breasts bounce, heavy and begging to be touched, above him. Reading his mind and placing the dagger to the side, she dug her nails into the fresher of the cuts, gently at first and adding pressure when he whimpered.
"You like this do you, Laufeyson?" She purred, tracing her fingers through the blood that covered her until she covered her breasts with it, massaging them so she felt the pleasure race through her veins, speeding her heart rate so that when Loki began to fuck up to her in earnest it practically matched her heart. His hand shot up to close over her neck, making her choke in surprise. He picked up the pace at her words, teeth clenched hard as he growled: "Don't. Call. Me. That."
She broke his hand away from her throat and pulled herself up and onto her haunches so she was off of him entirely. He snarled in anger, and once more she dug her nails into the cuts, reopening a few. "Don't fuck with me, Loki," she growled back, just as dangerous, before sinking hard and fast onto him. "You won't-ah-like what happens."
"Is that a threat?" He asked, each word punctuated with a loud groan as he arched his hips off the bed to meet her thrusts, and he might've thrown her off if she was any less practiced.
"You have no-idea." She said with the faintest hint of a grin, before reaching a hand between them and pressing her thumb hard to her clit, slick with her desire and practically making her scream with pleasure as Loki took his pace up another notch. It didn't take long for her to tighten around him, to shout and cry as she came trembling atop him. He didn't seem far away, though she slipped herself off from atop him before he come meet his orgasm himself. His cry of disbelief was cut off as she replaced her cunt with her mouth, sucking and hollowing her cheeks until he came, loud and hard, inside her mouth. A few drops of come managed to escape her closed lips, and after she'd swallowed she wiped them up with her fingertips and sucked the last drops off. When Loki pulled her closer for another kiss, tongue exploring her mouth, he groaned to taste himself mixed with his blood. Perfect.
