“And that’s how I seduced an important executive to obtain information for the agency,” Saeyoung concluded; a proud grin plastered on his face. He was sitting next to (y/n) on a black couch, talking about his former job.
“You dressed up as a maid? I cannot believe it!” She exclaimed.
“Oh, but it’s true~” He chuckled. “The guy was a groper...” He grimaced. A shiver ran down his back at the unpleasant memory.
“Oh, God...” She burst out laughing. “Good thing he didn’t find out you were a guy.”
“That’s because I rushed out of there as soon as his hand ran up my thighs. I even dropped my eyeshadow palette in the process... It shattered.” He sighed. “I didn’t know it was that fragile.” He pouted like a little child.
“Oh, that must have been unpleasant, to say the least.” She was trying to contain her laughter.
“Whoops! It’s almost time to pick up my date.” He said checking his phone.
“Where are you taking my twinie?” (y/n) asked enthusiastically.
“Your twinie?” He asked curiously.
“We have a lot of things in common so we call each other like that.” She smiled sheepishly.
“Oh~ So Saeran and I are twins and we are dating twins!” He chuckled. “Isn’t that funny, Saeran?”
“They are not twins for real, moron...” Saeran, who was watching them from across the room, rolled his eyes at his brother’s idiocy.
“So~ where are you taking her?” (y/n) asked again.
“That’s a secret, meow.” Saeyoung placed his index finger on his lips.
“You are taking her to the cat cafe, aren’t you?” The (h/c) woman raised an eyebrow playfully.
“And then I’ll take her to the movies~!” He exclaimed excitedly making her chuckle.
“Are you anxious?” She smiled gently and knowingly.
“Yeah, a little bit.” He scratched the back of his neck.
“Just be yourself, crack some jokes and it’ll be fine.”
“Will she get my sense of humour, though?” He pursed his lips and looked down.
“She will~ Relax.” She gave him a reassuring smile.
“Alright~!” He smiled back. “Thanks for the advice, my lady.” He stood up and bowed comically.
“Anytime.” She giggled.
“I’ll be home in a couple hours.”
“Have fun and be careful, Saeyoung.” He dabbed.
“Seven Zero Seven is always careful!” Saeran rolled his eyes while (y/n) chuckled at Saeyoung’s antics.
“Oh, and say hi to my twinie~!” She grinned.
“I will~ Bye, guys. Behave yourselves.” He winked at them jokingly before going out of the house.
“Bye.” She said covering her flushed cheeks with her hands.
“Stupid brother.” Saeran clicked his tongue and stomped out of the room. (y/n) followed him to their shared bedroom.
“Saeran? What’s wrong, sweetie?” The (h/c) haired woman asked worriedly as she closed the door behind her gingerly.
“’What’s wrong’ you ask?” He turned around and embraced her, nuzzling into her neck. She was taken aback by his sudden display of affection. “You have been neglecting me all day, doll.”
“W-what are you talking—?” He bit her neck harshly making her whimper.
“Instead, you have been talking with my stupid brother and laughing at his silly jokes.” His hands roamed up and down her body. “You know how hard it was for me to see how he made you smile? How he flashed you that stupid-ass smile of his? I would have punched him right in his face.” He groped her butt roughly, earning a moan out of her. “But, you know what the worst part was?” He stopped moving. “The worst part...” His velvety tone of voice suddenly became huskier and darker. A shiver ran down her back. “The worst part was that you, doll... you didn’t mind it at all.” He chuckled with mischief before biting her neck again breaking the skin. Then, he cleaned the wound with his tongue, savouring the metallic taste of her crimson blood.
(y/n) screamed and whimpered at the harsh bite he gave her neck and flinched when his tongue made contact with the wound.
“S-sae, that hurts, baby.”
“Imagine how much it hurt me watching you have fun with him...”
“I’m... I’m sorry. He was just worried about his date with (bf/n). So I was trying to help him, reassuring him that everything was going to be fine. You know how he is. He’s always goofing around... and I laughed at his jokes because I think they are funny. That’s all, baby.”
“You neglected me all day, doll. That's unacceptable.” He looked at her with lust-filled eyes, trying to pierce her with his gaze.
“I-I’m s—” He shook his head.
“I won’t let you off the hook for neglecting your master...” He lifted her, carrying her to the bed.
“W-what are you—”
“Silence, pet! You are not allowed to speak.” Saeran laid her down on the bed not so gently and flip her over so she was lying on her stomach. Then, he secured her wrists behind her back with a pair of handcuffs that were hidden under the pillows.
She wasn’t wearing any shoes so it was easier for Saeran to take off her pants and underwear and threw them on the floor. He licked his lips at the sight of her rounded butt and gave it a slap making her gasp.
“You’ve been a bad girl...” He smirked devilishly.
“I-I’m sorry.” She bit her lip in anticipation.
“You think that saying ‘sorry’ will get you out of this?” Saeran squeezed her butt cheeks harshly making her mewl. “You need to be punished, princess. I’ll spank your fine ass ten times and you’ll have t—”
“N-no!” She squirmed. “Saeran, please~”
“I didn’t give you permission to speak, now, did I? You want me to give you twenty spanks, then?” She stopped squirming and shook her head ‘no’. “Good. As I was saying, you have to count every single one of them, okay, dolly?” As soon as she nodded he spanked her hard making her scream in pain and pleasure. “Count them!”
“O-one.” Another harsh spank. “Aah! T-two!”
“Good girl, keep going.” He spanked her again.
“Ngh~ Three...” And again. “F-four.” And again. “Fi-aah-ve~!” And again. “S-six...please, Saeran. It hurts...” She whimpered and he slapped her butt even harder.
“Address me properly, pet!” he ordered in an authoritative tone.
“Aaah! S-sorry, master. Sevengh...” He spanked her again. A red imprint of his hand started forming on her ass.
“Ahh! Eight~ P-please, master, stop... it hurts so much.” She pleaded with tears in her eyes.
“You shouldn't tell me to stop when you are clearly enjoying it...” He said looking at her dripping pussy before spanking her again.
“Aaah~ Nine...” She whimpered.
“You are so wet, what a slut.” He smirked. “One more spank and your punishment will be over, pet~” He squeezed her butt. “Are you ready?” Without waiting for her to reply, he spanked her for the last time as hard as he could, making her scream in both pleasure and pain. A few tears rolled down her cheeks.
“T-ten. Mmm~” She whimpered.
“Tsk, tsk, tsk. Getting all worked up just from a few spanks, you dirty slut.” He chuckled wickedly.
“I... I’m your slut!” She mumbled a little embarrassed.
“Of course you are~”
“C-can you take the handcuffs off, now, M-master?”
“Why would I do that, doll?”
“Y-you said my punishment was over...”
“It is over. But that doesn’t mean I am done with you~” He chuckled again.
He climbed on the bed; his knees were on either side of her. Then, he leant down and pressed his crotch against her butt while sliding his cold hands under her shirt, making her shiver.
“You are not wearing a bra.” He pointed out. Then, he slowly ran his hands over her tender skin cupping her huge breasts roughly. “Whose are these? Hm?” He squeezed them.
“Ngh, yours. They are yours, Master~” She moaned softly.
“Good~” He fondled her breasts and played with her nipples, twisting, pinching and pulling them harshly, making her moan and grind her butt against his crotch. He groaned and bit her neck hard, leaving a few marks.
“Ma-master~ s-stop.” She moaned and ground her but against him again.
“You tell me to stop but you keep rubbing your butt against me, you dirty slut.” He stated, making her moan. He, then, proceeded to take his trousers and underwear off, throwing them on the floor along with her clothes.
(y/n) tried to take a look but he forcefully pushed her head down against the bed.
“Do not move, pet.” He lifted her hips a little bit with his free hand and placed his big, hard cock in between her wet folds.
“Mngh~ master~” He could hear her muffled moans.
Then, he pushed two fingers inside of her, making her gasp. He thrust his fingers in and out of her slowly while rubbing his dick against her pussy. The tip of his cock teasing her clitoris gently. She squirmed under him.
“Master, please~” She whimpered. He removed his hand from her head and placed it on her hips.
“What is it?” He asked with a smirk plastered on his handsome face, rubbing her g-spot with his fingers.
“I w-want... Ngh~” She panted.
“What do you want, hm~?” He shoved a third finger inside of her and pushed them in and out faster.
“P-please, M-master-ahng~”
“Beg for what you want and maybe I'll give it to you.”
“I... I want you. I need y-you.” She begged breathlessly.
“Hm~ I don’t think that’ll be enough, doll.” He spanked her butt.
“Aaah~! I want you, inside of me, m-master-ngh~!”
“I’m already inside of you, princess.” He dug his nails into her butt cheeks.
“I want your cock... inside of me.” She whimpered as he pulled his fingers out of her.
“Oh~ and how badly do you want it, whore?” He rubbed the tip of his dick against her wet slit.
“I-I want you to fuck me so hard with that big cock of yours, master, please!” She begged urgently.
“What a cock-slut you are~” Saeran suddenly thrust into her harshly. A loud moan came out of her mouth.
He grunted and thrust into her in a slow and steady pace, gripping her hips roughly with one hand while he reached down, between her legs, with his other hand, to play with her swollen mound.
“Mngh~ Yes, master~” She moaned as he thrust deeper inside of her hitting her cervix. She moved her hips, trying to meet some of his thrusts.
“Whose pussy is this, huh?” He groaned.
“It’s y-yours, master~”
“You are a good little whore~” She tightened around his cock.
“F-faster, master. Please~” He picked up his pace, thrusting into her harder and deeper as well; hitting her cervix roughly with every thrust, making her moan loudly. He continued playing with her clitoris, pinching and rubbing it with his fingers.
“Whose ass is this, I wonder~?” He squeezed her butt using the hand that was previously holding her hips.
“Ngh~! It’s yours, master~” She tightened around him again.
“Oh really?” He pressed and rubbed his thumb against her puckered hole.
“Master? W-what are you doing?” He pulled out of her for a bit to rub his thumb against her dripping pussy. Then, he pushed it into her butthole while thrusting into her again.
“Ngh-ahh~! M-master noo~!” He pushed his finger in and out of her in sync with thrusts. “Baby, it hurts~”
“It hurts but still you like it, don't you? You are so wet and you keep tightening around my cock.” He smirked and thrust harshly inside of her, hitting her cervix every time.
She tried to deny it but instead, she moaned loudly at him when he hit her cervix, tightening around him even more.
“You slut...” He groaned. “You keep tightening around me... You want my cum so badly, don’t you? You want to be filled to the brim with my warm and sticky cum... Such a dirty slut ngh~ j-just how I like it.” He thrust into her even faster, making her throw her head back and scream in pleasure.
“M-master~ I'm, ah~” She tightened around him harshly.
“What is it?” He panted. She was a panting and moaning mess; drool was dripping from her mouth onto the bed sheets and her eyes were filled with tears from all the pleasure he was giving her.
“I’m so close, master~”
“You are a good little whore, aren’t you?”
“You always feel good inside aah~ of me ngh~”
“I’m the only one allowed...” He groaned. “...to be inside of you.” (y/n) screamed and tightened around him.
“I’m yours!” He kept hitting her cervix harshly and rubbed her clitoris faster. “Oh~ master! Right there~” She moaned his name loudly. “I’m cuming~!” He twitched inside of her as her walls spasmed around his shaft.
“Yes, you are only m-mine~ a-ahh~!” He moaned softly as he released his sperm inside of her.
“Sae~ran~!” She screamed his name as he filled her, causing her to cum as well. Saeran continued thrusting inside of her a few more times, riding both of their orgasms. (y/n) collapsed into the mattress panting heavily.
“I’m not... done with you... just yet.” He pulled out, panting.
(y/n) felt his dick poking her butthole and she bit her lip. He thrust inside of her, making her arch her back and scream his name.
“Sae~!” She wiggled her butt a bit.
“Hm?” He groans, slowly getting all the way inside.
She cumed a little from him forcing himself inside, twitching slightly from the pleasure. Then, she buried her face into the pillows, panting and whimpering softly.
“What a cock whore you are~” He groaned. “You cumed again just because I’m fucking your tight little ass without lube.” He chuckled softly. The red-haired man proceeded to thrust in and out of her at a slow pace. (y/n) moaned and whimpered as she felt herself getting wetter.
“I’m your slut, master.” She panted.
“Damn right, you are.” He groaned grabbing a fistful of her silky hair, pulling it harshly as he fucked her roughly. A high-pitched moan escaped her lips.
Saeran, once again, reached down between her legs to rub her clitoris.
“Cum for me, pet.”
The (h/c) haired woman screamed and whimpered as she cumed again.
“Good girl,” He said breathing heavily. After freeing her wrists, he pulled out and flipped her over so she was lying on her back. "Stay there. I need to clean myself," He ordered before walking to the bathroom. (y/n) could hear the water from the faucet running. After a few seconds he came back, a smirk was plastered on his face.
“Take your shirt off.” He said as he took off his shirt as well. “Raise your arms.” He ordered. She did as she was told and he handcuffed her again.
Once more, Saeran positioned himself in between her legs and pushed his cock violently inside of her wet vagina. (y/n), being so sensitive after having cumed twice, screamed loudly.
“Ngh, no~” He fucked her fast and harder.
“You thought this was over?” He chuckled. “How cute.” She squirmed under him, moaning loudly and biting her lower lip to calm down a bit.
“No, doll. I’ll be the only one biting those plump lips of yours.” He leant down and crashed his lips roughly against hers, biting and sucking on her bottom lip. She moaned into his mouth and shoved her tongue inside, deepening the kiss. He groped her breasts, massaging them roughly and trapped her tongue between his teeth, nipping it slightly and sucking on it. She moaned into his mouth before pulling back from the heated kiss.
“Saeran, please, take the cuffs off me. Please, master~?” After considering it for a while, he freed her hands. Then, he grabbed her hips hard and pulled his cock out before thrusting into her again hitting her g-spot.
As soon as her hands were free, she clung to him and dragged her nails down his back while he kept abusing her g-spot with every single thrust.
“Ngh~ y-you feel amazing, little slut.” He praised her and gripped her hips tightly with his hands, digging his fingers and leaving several marks all around (y/n)'s hips.
The (h/c) haired woman tightened around his shaft and dragged her nails down his back harshly, trying to make her screams less intense by biting his neck and sucking on it.
He hissed at the pain of her nails on his back and her teeth on his neck and reached down with his hand to massage her swollen clitoris, again, adding more pressure this time, making her squirt a little as she arched her back and moaned his name out loud.
“M-more~!” She begged.
Saeran rubbed her clit with his thumb faster and thrust deeper inside of her hitting her cervix over and over again. She dug her nails into his shoulders breaking the skin. She was closed and he knew it. He could feel her walls gripping his cock harshly as if her pussy was sucking his cock in. He leant down to leave hickeys and love bites over her bouncy breasts, making her moan with delight.
The feeling of her nails digging into his shoulders and her walls tightening around his dick drove him crazy and with another harsh thrust, he cumed inside of her again, grunting and panting.
(y/n)’s toes curled and her nails dug deeper into his shoulders as she, too, cumed, screaming his name over and over again.
Not pulling out, Saeran collapsed on top of her panting heavily. He placed one of his hands on her cheek and rubbed it lovingly, nuzzling his face into her neck. She wrapped her arms around him and rubbed his back, relaxing at the feeling of his body pressure on her, finding it comforting.
“I love you, Saeran.” She kissed his cheek softly.
“I... I love you too.” He mumbled before raising his head, kissing her lips tenderly. He nuzzled into her neck again and played with her hair until she fell asleep in his loving arms.
~The next morning~
The twins were in the kitchen enjoying breakfast when (y/n) walked in. Saeyoung noticed that she was limping slightly and when he saw the love bites and hickeys on her neck, he smirked.
“I told you both to behave yourselves, naughty kids.” He shook his head playfully.
“Fuck off, Saeyoung.” (y/n) replied grumpily, wincing at the pain on her hips.
“Are you jealous of the fact that I have more sex than you do, brother?” Saeyoung grinned and was going to reply but Saeran spoke again. “Although, I wonder, have you done it with (bf/n) last night? You came back pretty late.” He mused.
“A-ah w-what!?” Saeyoung’s cheeks turned bright red.
“Oh? You two did it?” (y/n) asked amused.
“No!” He stood up abruptly. “I haven’t even thought of doing such things with her!” He exclaimed embarrassed. “I’ll be in my room praying for your sinner souls.” He gripped his cross necklace tightly and walked out of the kitchen.
“Aaaw, he’s all flustered~ I can’t wait to tell (bf/n) about this.” (y/n) chuckled lightly.
“Hey, are you... alright?” He stood up and walked to her with a worried look on his face.
“I’m a bit sore.” She winced again.
“Sorry.” He mumbled.
“Well, ice-cream and cuddles will make me feel better, ya know.~” He hugged her and kissed her lips softly.
