ShinKami Smut (ABO)

Alpha Shinso
Omega Kaminari

Kaminari hated his heats. He was always so desperate and he had no mate to help him. He had already made a nest in his bed and was curled up desperately trying to relieve himself. He clawed at the blankets until he found a pillow which he started rutting against while whimpering. "P-please, fuck~" He whines and humps the pillow needily. "Kami? I need the notes from VA cl- Kami?" Someone says as they walk in and Kaminari doesn't have the energy to care, he just wants to cum, but can't seem to no matter how hard he tries.

Shinso closes and locks the door then sits in Kaminari's small nest. "Kami, can I help you?" Shinso asks softly and Kaminari nods eagerly. "C'mere." Shinso says gently and grabs Kaminari by the hips, pulling him onto his lap. Kaminari whimpers and grinds against Shinso's lap. "Fuck me~" He groans softly and Shinso pulls their shirts off. Kaminari tugs at the waist band of Shinso's pants and Shinso flips them over to strip both of them naked. Kaminari is so wet he's practically dripping. "Ready?" Shinso asks and Kaminari whines, "Yes! Please~"

Shinso slides a finger inside Kaminari, who whines in protest. "No prep, I'm ready, please fuck, everything is too hot." He gasps and Shinso smiles, kissing over Kaminari's unclaimed marking area teasingly. "Spread your legs a bit more, baby boy." Shinso whispers in Kaminari's ear and Kaminari immediately does as he's told. Shinso lines them up and gently slides into Kaminari. Kaminari wraps his arms around Shinso and pulls him closer.

Shinso starts off gentle, rocking back and forth and letting Kaminari adjust, but with Kaminari's consistent whimpering and pleading he gets rougher and pins Kaminari's legs open as he pushes into him. Kaminari tangles his fingers in Shinso's hair and moans softly. Shinso starts pounding into him, holding his hips as they make the bed creak. "T-Toshi!" Kaminari moans as Shinso's knot starts to grow. "Oh fuck, Kami~" Shinso moans back and Kaminari tosses his head back.

Shinso starts to pull Kaminari's hips back and forth in rhythm with his thrusts. Kaminari just clings to Shinso and let's Shinso ruin him. Shinso slams onto Kaminari as he kisses his marking area heavily. "Fuck, you feel so good." Shinso moans and Kaminari's breathing hitches. "M-mark me." Kaminari begs and Shinso bites into his marking area without a second thought. Kaminari moans loudly and barely holds back from coming right there.

Shinso has enough sense to press gentle kisses to the newly formed mark and keep pounding into him. "Toshi, I-I'm gonna cum!" Kaminari gasps, trying to hold back. "Ready for my knot?" Shinso asks and Kaminari nods eagerly. Shinso slams into him a final time, pushing all the way in with his knot included. Shinso comes with Kaminari, both moaning and holding each other tightly. "Good boy, stay still until I can pull out." Shinso says and Kaminari nods, letting his head drop backwards with a satisfied sigh. "Oh that feels so much better." Kaminari says softly as Shinso presses soft kisses to his new mark.

"Does it hurt, baby?" Shinso asks and Kaminari says, "Its just a little sore." Shinso nods and brushes the hair from his face. "You're so beautiful." He says softly and Kaminari dips his head, blushing. "Shinsooo~" he whines, "Don't say that~" Shinso laughs softly and ruffles his hair gently. "Aww, what happened to Toshi~?" Shinso teases and Kaminari groans. "You're too hot, you make me nervous." Kaminari mutters and Shinso laughs. "I can't call you beautiful but you can call me hot? Sounds like a double standard there, babe." Shinso teases further as Kaminari gets flustered.

"Toshi!" He says and covers his face. "It sounds just as cute as when you're moaning." Shinso says as he kisses Kaminari's mark gently, running his tongue over it. Kaminari gasps softly at how surprisingly good Shinso's tongue feels over his sensitive mark. "Here." Shinso says and pulls out of Kaminari before flipping them where Kaminari is curled into his chest. "Hitoshi..." Kaminari says softly and looks up. "Hm?" Shinso asks and looks down at Kaminari.

"You marked me because you want me, right?" Kaminari asks, his voice tense and unsure. "Yes, of course I want you. I don't call just anyone baby." Shinso says with a soft frown and reaches down to play with Kaminari's hair. Kaminari leans into it and let's his head drop, relaxing with the assurance that everything is okay. "Just... just don't leave, okay? I don't mean to be clingy or anything, I just-"

"Yeah, I get it. I like you for way more than sex, baby." Shinso says and Kaminari smiles. "Love you."
