IidaSero Smut

"Sero, you are pushing it. Come here and cuddle." Iida says and pats his lap. Sero happily sits on his dom's lap and cuddles into his chest. "There, good boy." Iida sighs and rubs Sero's back. He's been purposefully misbehaving all day and it's the first time he's taken an order and followed it. Sero bites Iida's neck and Iida frowns. "Release." He says and Sero stays perfectly still and where he is. Iida growls and grabs Sero's hair, yanking his head back. "I have been patient all day. I have let much more than I should've go and I've had about enough." Iida says and forces Sero to lay back. Sero blinks in surprise and slides a hand down to cover his growing boner. "Tenya-"

"Is that what you call me? Really? Looks like I'll have to be rougher than I thought." Iida says sharply, pulling out a lock box from under the bed. Sero's eyes widen slightly in excitement and curiosity, he knows that lock box all too well. Iida grabs lube, a vibrating dildo, padded hand cuffs, silk rope, a collar, and a blindfold. Sero is already sitting and squirming. "Hands." Iida demands and pats his lap.

Sero obediently offers his hands, palms down in Iida's lap. Iida uses the handcuffs to bind them together. He leans down into Sero's ear and whispers, "Good boy." Sero squirms slightly, incredibly turned on by the praise. Iida sits on the bed and yanks Sero over his lap, getting a yelp. Iida rubs his ass teasingly. "Sir, I- ah!" Sero moans as Iida spanks him. "I don't hear counting, pet." Iida says and spanks him again. "Shit- one!" Sero gasps as Iida leaves a handprint with the next one. "Two!" He whimpers and squirms in Iida's lap.

Iida rubs the bruise gently before slamming his hand down again. "T-three- hnngh- f-four!" Sero whines as Iida does two quickly. Iida spanks him again, making a tear roll down Sero's face as he whimpers a "f-five". "Are you ready to sit?" Iida asks and Sero nods, eyes still pricking with tears over the lingering pain. Sero sits up on the bed with Iida's help, flinching at the pain radiating from the red marks on his ass.

Iida grabs Sero's wrists and pushes him back, pinning them over his head. He strips Sero's clothes off from his bottom half down. Sero's breathing hitches as Iida runs his hands down the sub's sides. Sero tilts his head back with a needy sigh as Iida holds his waist and kisses his neck. "Sit up a little." Iida says and Sero stays perfectly still. Iida grabs him by the neck and yanks him up. "When I say sit, you sit without question. Or do we need to re-train you?" Iida asks and Sero squirms.

Iida takes his hand away to clip a dog collar onto Sero's neck. "Fuck you." Sero says defiantly then Iida ties a blindfold around his head, pulling it comfortably over his eyes. "Too tight?" Iida asks softly, letting Sero know its for safety and not play. "No, it's good." Sero says and Iida nods. Iida grabs the collar and pulls forward. Sero is pulled forward with it. "Now be a good boy and behave." Iida growls and Sero gasps quietly.

Iida makes him lay back and kisses over his chest, making Sero squirm. Iida licks over Sero's hard on softly and Sero groans. "Masterrrr~" He whines and Iida smirks. "What, not so bratty now?" Iida teases and kisses his inner hip. Sero whimpers and tries to spread his legs more, trying to present for Iida. Iida presses the head of the dildo at Sero's hole, slick with lube. Sero whines and squirms as Iida turns the toy on, causing it to vibrate. "Shit." Sero gasps as Iida slowly presses it inside him. Sero's legs twitch as he balls his fists up. Sero's cuffed hands fly over his mouth to muffle his pathetic whimpering.

Iida growls and yanks his hands away. "No, you don't get to be quiet. I don't want you holding anything back." Iida snaps and pins them to his stomach. "Master, please move it, I need more." Sero whines and tries to push against Iida's hand. Iida pushes the whole thing in. "Fuck!" Sero gasps and reaches for Iida, whining. Iida offers his free hand and Sero clings to it. "Are you gonna be a good boy?" Iida asks as he starts sliding the dildo in and out.

Sero groans, biting his lip and grip tightening on Iida's hand. Iida only gets rougher, starting to hit Sero's soft spot every time. Sero whines and tries to tug Iida's hand up. "Aw, you want me to choke you? Beg." Iida says firmly and Sero squirms. "Make me." He says shakily and Iida laughs. "Oh, sweet little toy. I'll do so much more than make you." Iida snaps and pulls his hand away from Sero, making him whimper. "I'm still right here, pet. Just because you can't see me doesn't mean I'm not here." Iida says and sits up, still pumping the toy in and out of the whining sub, to hold Sero's cheek gently.

Sero leans into it and whimpers, starting to get kinda close. "You're just desperate for me to touch you, huh?" Iida says as Sero tosses his head back in pleasure. "Too bad." Iida says and pulls the dildo out completely, turning it off. "Fuck!" Sero gasps and squirms, desperately trying to rub his thighs together. "Poor baby, can't cum?" Iida says teasingly and cups Sero's face gently.

"Master, I need to cum." He says urgently but Iida just laughs. "You should've obeyed then. So cute." Iida coos and rubs his thumb over Sero's cheek as he squirms and struggles. "Please, please let me cum- Master, please." Sero whimpers and leans into Iida's hand desperately. "Are you going to behave now?" Iida says and Sero nods. "Yes, yes I'll be good." He agrees and squirms, trying to get Iida's hand around his neck. Iida grabs his neck and chokes him. "Be still." Iida says and Sero freezes where he is. "Good boy. Spread your legs." He says and Sero obeys. Iida pushes his pants and boxers off. He takes his hand away to kiss Sero's neck heavily.

"Ready?" Iida asks and Sero nods. "Yes, sir." Sero says and Iida smirks, lining his hard cock up with Sero's hole. Iida is slow at first, slowly pushing inside. Sero moans and throws his head back as Iida rocks in and out of him steadily. "Fuck, such a pretty little pet. So good for me." Iida praises and Sero keens. Iida tilts his head back with a groan as he fucks Sero. His hand slides around Sero's neck and stays there.

Sero grabs Iida's arm, holding tightly to keep his hand there and just to be able to cling to something. Iida smiles at the sight, his sub with head tilted back, cuffed and blindfolded clinging to his arm. "Such a beautiful pet." Iida coos as he slams into Sero. "Fuck!" Sero gasps, whimpering and trying to push back against Iida. "I'm close, sir." Sero says urgently and keeps his legs wide open.

"You can finish. Be a good boy for me and finish." Iida encourages and Sero whines. "A-ah, Master!" Sero moans as he finishes, gripping Iida's arm as Iida fucks him through it. "Shit, you're going to make me finish." Iida groans and moves his hands to grip Sero's hips. He pulls out quickly and starts fucking into his hand. "Stay." Iida says and moves to have his cock close to Sero's face, still pumping his hand up and down his dick. "Mouth open." Iida says and Sero's mouth instantly flies open, just in time for Iida to fill it with cum.

"Ah, shit. Good pet, good." Iida sighs and pushes Sero's mouth closed. "Swallow for me." Iida says and Sero swallows. Iida takes the blindfold off Sero and pulls him up a bit. He looks up into Sero's eyes as he licks the cum off his stomach and chest. Sero squirms a little but allows it. Iida takes off the handcuffs and pulls him over to cuddle. "Time to calm down, baby." Iida coos and rubs his back.
