a/n: I don’t know how to write smut anymore, moreover a sub! male genre. 😭 Please let this slip. 😥 I’m just in a Shotaro mood lately and I recklessly applied for a collab without thinking about it.
You believed it was Yuta’s fault.
It just randomly popped in your conversation, how you thought Shotaro looks so good dancing and that he’s more handsome now that he has longer hair. It’s a feedback since your boyfriend takes care of the younger Japanese boy like a real brother. You didn’t know that Yuta would take it the wrong way.
“Actually, Shotaro is a virgin.” Your boyfriend claimed one night while cuddling naked in bed that startled you. Why did he suddenly say that? “I’m worried about that kid and his sex life.”
Isn’t it too personal for the younger boy? And if they have that conversation, Shotaro sharing that fact about him, does that mean Yuta shares to him about the things you do in the bedroom? You weren’t exactly a saint, not a whore either but how can you resist a guy like Yuta Nakamoto?
The thought he implanted in your brain made your head swirl to different directions.
Instead of complimenting Shotaro in his dance skills, your brain kept on trailing to images of his thrusts. Instead of staring at his silky hair, your eyes would wander at the sweat dripping from his forehead. The image of a younger boy who was always smiling was easily replaced with a sexy younger man.
Something new. You wanted to corrupt him. So bad.
The want even transcends to your dreams that you woke up panting after being so turned on by the image of Shotaro eating you. “Kinky baby.” Yuta whispered, chuckling next to you. “You want him that bad?” Your eyes widened in surprise. “You’re calling Shotaro’s name. Should I be bothered?” You shook your head but he only stood up in his naked glory, laughing to himself.
You watched as Yuta wore a clean shirt and his sweatpants, taking the keys of his car and his phone. Where is he going? “Honey,” He called then sat on the edge of the bed. “Did you know that Shotaro touches himself while thinking of you?” You only stared in surprise. What? Did you hear him wrong? “He says he likes you in that pink skirt you always wear.” He kissed your forehead before exiting the room while chuckling.
Fuck! Now, you want him more.
You believed it was Yuta’s fault. He sent you a video he had taken of the younger Japanese jerking himself, a whisper of your name in soft voice but audible. No, it is indeed Yuta’s fault that you’re thirsting over this guy.
Your annoyance to Yuta only grew when Shotaro appeared on your doorway, breathing hard. “Noona.” He called, voice trembling. “I’m sorry. I can explain. Please don’t be mad at me.” You gave him a curious look. Mad at what? “You’re so pretty and you’re so nice to me…”
“Wait? Is this because of the video?” He nodded then rubbed his palms together, apologizing once again. “Of you masturbating?”
His eyes widened in surprise. He looks so cute. And confused.
“What?” He asked. “I was referring to the video hyung took of me when I said I like you.” He blinked. “A video of me masturbating?”
Oh my God, Yuta is just so mean.
“Noona…” He called that made you bit your lip. His lips are quivering. He might cry. Why are you so turned on? “I’m sorry.” He even kneeled on the floor, bowing at you. “I’m sorry.”
You sat down then held his cheek. “Sho, please stop. It’s fine.”
“Hyung said you’re mad at me.” But you shook your head, smiling at him. “You’re not?”
His eyes became curved lines. So cute. He’s still a little boy. You asked him to stand up and come inside with you. “You smell so good, noona.” You stopped in your tracks then turned to him. He also looked surprised at what he said that he rubbed the back of his neck, avoiding your look. Really cute.
And you want him again.
You stepped forward, closing the distance between the two of you. “Do you want to kiss me, Sho?”
“Hyung will kill me and I don’t know how to.”
You bit your lip to prevent a smile. “Yuta brought you here, didn’t he?” He nodded, “Don’t worry about it.” You stepped closer as he breathed hard. “Do you want noona to show you?”
He leaned before answering, hovering his lips on yours. For a virgin, he’s pretty bold. This is nice.
A change. Something new.
His kiss was hungry, a passionate kiss you missed. Yuta used to kiss you like this, needing. But lately, he's always so rough on you. Shotaro's soft lips felt so nostalgic. You slipped a tongue inside his mouth and he gasped, eyes widening in surprise.
You smiled when you pulled out of the kiss and he was breathing hard. "That is how you kiss, baby." You saw him gulp before pushing you by the wall and leaning in to kiss you again. He used your technique, slithering his tongue inside you.
A fast learner. You'll have fun teaching Shotaro.
Your hands trailed on his shoulder to his torso, feeling the lean body that is the result of all the dancing. Contrast on the muscled pecs and chiseled abs that your boyfriend has. He pulled out of the kiss, gasping for air, when your hands went to the waistband of his jeans. "Noona," he called in a breathless state. He sounds so sexy saying that word. Is it your kink now? Being called noona? "Hyung will kill me."
You giggled. He's so adorable. Your hand touched the outline of his bulge and he closed his eyes while a whimper escaped his lips. "Don't think about him and just focus on me." You realized you should do the same thing. You wanted this to be memorable for Shotaro. "Do you want to do it or not?" You put some pressure on his crotch and he moaned, arching his back forward and holding your shoulder.
You're perfectly aware that you're luring him to you. You wanted him to want you too. The same way you're craving for him. "Sho, do you want this?" You placed his hand above your clothed breasts. A sharp gasp escaped his lips. "Answer me."
His eyes turned darker. "Yes, noona." He said in a soft voice. "Please take me."
You smirked before taking his fingers in your mouth, not breaking eye contact. The look of want. You finally got it. "Get inside the room and get undressed. Wait for me." He nodded, obediently following you as if in a trance of a spell.
It's his first time, you kept on repeating to yourself. Even if you wanted to be hard on him, you can't. You don't want to scare the baby boy. A smirk appeared on your lips as you glanced at the collection of toys in your dresser. Should you cuff him? But he's obedient. A vibrator? Can he take it? Instead of taking something out from the dresser, you decided to just do the deed in your own hands.
The young Japanese man's eyes widened when you entered the bedroom, his gaze fell on the pink skirt you were wearing. You bit your bottom lip as you saw how his uncovered cock twitched. His lips were agape, one hand on his thigh while the other touched his chest dangerously close to his nipple. "Were you touching yourself, Sho?" You asked while raising an eyebrow at him, your hands crossed on your chest emphasizing the red lace brassiere covering your breasts. "Did I tell you to touch yourself?"
"No." He said as if letting out a heavy breath. "But…"
"No buts, baby." His cock twitched again, making you smirk. "You like that Taro?" You whispered, leaning close to him. "Me calling you baby?" Again, a twitch. "Do you want noona to call you baby?" He hissed before nodding. "Words, baby."
He heaved a sigh. "Yes, noona."
"Arms up." You commanded as he reluctantly followed you. "This is your first time, am I correct?" He mumbled a soft yes. "I won't be cruel to you so you better listen to me. Are we clear?"
"Yes, noona."
Your lips formed a smile. "Give me a safe word, baby."
He whimpered when you sat on his lap. "I thought you won't be cruel." And you just chuckled at that. "Sushi." He shouted when your cold hands trailed on his exposed chest. "Safe word is sushi." You giggled at his closed eyes, arms raised above his head. "Noona, I'm scared."
You kissed his lips, hand holding his wrists as the fabric of your skirt rubbed against his cock. You licked his bottom lip and watched as he slowly opened his eyes to stare at you. "I won't hurt you, baby. Just remember your safe word and I will stop. Is that alright with you?" He nodded with a gasp when your fingers trailed on his arm.
His whimpers resonated through the room while you pepper his torso with open-mouthed kisses, lightly sucking and licking his skin that left reddish marks. This will surely show in the coming days. A masterpiece. Your masterpiece. You licked his erect nipple which earned a yelp from him before sucking on it. He squirmed but you gave him a glare before nibbling on the other nipple, eyes not leaving his. "Noona, please."
The kisses went south to his stomach, alternating the licking and sucking until it created a bruise on his skin. His cock hitting your neck as he kept on squirming, pleading for mercy. A giggle escaped your lips when he gave a guttural moan followed by cum leaking from his throbbing cock. Already? You're just starting.
His cum shot to your breasts, some to your neck which made you glare at him. His pleasured face, eyes closed and mouth agape, made you lick your lips. God, he's so cute. "Did I say you can cum, Shotaro?" His eyes opened wide, staring at you in surprise.
The younger muttered an 'Oh my God' then kept on apologizing. "Maybe you should clean up your mess, baby." You hovered above him, raising an eyebrow. He raised his head to lick the cum on the valley of your breasts, breathing harshly. "Remove my bra." It's funny how you even guided him to unhook the red brassiere before his eyes widened at your exposed breasts. "Suck." You commanded and he nodded.
Shotaro licked the side of your left breast and made sure that it's clean of his cum before nibbling on your nipple, the same way you did on him. A moan escaped your lips when his tongue played with the erect nub. He's such a fast learner. If it didn't come from his mouth, you will never believe that he doesn't have experience. He knew how to turn you on or maybe it's just been too long since your breasts were played gently like this. You probably missed the feeling. A whisper of his name escaped your lips when he moved to the other breast, repeating the same action.
He jerked his hip up and you felt his cock hardening once again. That fast? Is he that turned on by this? You rubbed your clothed core on his cock that you whined in pain when he suddenly bit your nipple. "Sho!"
"I'm sorry, noona. That just feels so good." You kept on grinding against his erection. His face was full of pleasure as he kept calling your name repeatedly. A whine escaped his lips when you raised yourself from the bed, sitting on his lap and smirking at his needy expression. "Noona please."
Your pointer grazed the tip of his cock, making the younger jerk his hip upward. "Please what?" His erection felt hot on your fingertips. His body squirming at the contact. "If you can't take this, you can say the safe word." You fisted his cock, hand going from base to tip then rubbed the tip with your thumb. He thrust his hip up but you pushed him down to the mattress that made him wide-eyed.
Shotaro's hands were on his side, tightly grasping the sheet. He was biting his lip and a faint red tint can be seen under the pearly whites, his forehead shimmering in sweat. "Noona!" He called before white liquid oozed from the tip of his cock. Your hand moved faster, eyes locked on him. A snicker escaped your lips as he stared at you as if pleading, "Noona, I can't anymore." A tear welled in his eyes as he desperately thrust his hip to your hand, coating it with his cum.
He was breathless, watching as you put the hand on your mouth and licked his cum. "Can you still do another round?" But he shook his head, saying the word sushi in a soft voice. “I’m sorry, Sho.” You cooed, holding his cheek. “Are you alright, baby?” He nodded, panting hard. “I’m sorry.”
Shotaro shook his head and in a breathless voice whispered, “I’m fine, noona.” You stood up but he held the hem of your skirt, lightly tugging on it. “Can we...” He started, staring at you with those pleading eyes. “Can we do this again, noona?”
You kissed his forehead, wiping the sweat and tears on his cheek before nodding at him. “Of course, Sho.” You grinned. “Get some rest. We’ll clean up later.” He nodded, closing his eyes as if waiting for it.
Fuck, you might have enjoyed this so much.
You closed the door gently after pulling the blankets up for the naked guy sleeping in your bed. You almost felt your heart jumping out of your chest when you saw your boyfriend seated on the couch, smirking at you. “Did you have fun?”
A smile crept on your lips, nodding while you sat beside him. “Yuta, can we adopt Shotaro?”
“Adopt?” He asked raising an eyebrow. “He’s not a dog, you know?”
You giggled. “I know,” You started, circling a finger on Yuta’s chest. “But he has the potential of being an amazing sub. Maybe we can spice up things and play with Shotaro while showing him things.”
He raised an eyebrow then kissed the top of your head. “We’ll ask Shotaro when he wakes up.” You nodded, grinning at him. “Now, baby girl,” His voice became lower that startled you. “On my lap, ten hits.”
“Ten?”
“For making me wait while you had fun with your baby boy,” Yuta said with a smirk. “Make me talk some more and I’ll double it.”
You gasped, lying on his lap. “This is your fault, you know?” But he just smirked.
The pain didn’t even resonate on your body. All that matters now is that you’ll have a new playmate. A baby boy named Osaki Shotaro.
