When the blonde came back from the shopping, he went straight to Jungkook's office but he wasn't there. He became confused and went to their room but the ravenette wasn't there too. He grew curious and went to the living room where the Golden five were talking about God knows what.

''Namjoon Hyung...where is Kookie?'' He asked with furrowed burrows.

''Ah...He was getting tensed when you guys took long. He was ready to go to the mall after you but when we didn't let him saying that you will be mad later, he went to Gym to let out his tension on poor sand bag and his body. He must still be there.'' The hacker informed making Taehyung smile.

Typical Jungkook.

''Okay then...I'll be going there.'' With that, Taehyung went to his room and changed into his Gym outfit.

Looking into the mirror, he smirked.

Why not exercise together?

He went out to go to the Gym leaving the note which that man in the mall had put in the pocket of his pants in the laundry basket.

Wearing a sports bra with track pants and sports shoes, the blonde entered the gym with a naughty and dirty plan already in his mind.

The gym was dark themed laced with every modern workout equipment. One of the wall was covered with mirror from one end to the other like they have in dance studios. From adjustable bench to treadmill, sandbag to dumbbell stands full of various dumbbells, flat bench press to lat pulling down. A gym bike was standing in one corner of the room with a pull up pole slightly away from it. TRX bands hanging from the ceiling and some exercise balls lying in one corner. A cupboard with mini towels to wipe the sweat was standing to the far right of the gym.

The floor was covered with soft yoga mats.

The mafia leader was shirtless and his upper body was glistening with sweat as he worked out hard to divert his mind from Taehyung being in the shopping mall without any security. His face was neutral as he panted but didn't stopped. The black hairs sticking to his forehead covering those dark eyes and the flexing muscles of his body covered with ink made Taehyung lick his lips.

''Woah...easy boy!!'' He shouted when Jungkook didn't noticed him and kept doing pushups. The ravenette immediately stopped and looked at the blonde who was already eye fucking him. The mafia leader smirked and continued his push ups.

''How did your shopping went doll?'' He asked sinisterly.

''It was good...but now I think i'd rather workout with you then going on shopping.'' He said stretching his arms and legs to warm up his body.

''Really? I am afraid you won't be able to keep up w-with me, princess.'' The mafia leader teased with a smirk.

''You never know, Mr Jeon...'' The blonde winked working on warming up his body.

'' Ohkay.Then.. umm I guess I would love to know.'' the mafia leader said standing up straight and look at Taehyung with a tilted neck, his eyes darkening.

''Where should we start with, Mr Jeon?'' Taehyung asked once his body was ready for heavier exercise.

''Let's start with testing your flexibility...shall we?'' The mafia leader asked walking towards the blonde who looked at Jungkook amusedly.

''Sure....Just sit down on that bench and watch me.'' He winked walking a little away from the mafia leader. The ravenette sat down on the couch lying in the centre of the Gym and waited for Taehyung to start his show.

The blonde lied down on his back on the yoga mat and looked at Jungkook.

''Watch me, baby.'' With that, he picked up his right leg until it made a ninety degree angel with the floor and held the toe of his feet with his right hand, his left leg effortlessly glued to the ground and Jungkook couldn't help getting a little excited.

''Is that all, princess?'' the ravenette asked in amusement.

'' That's was warm up sweetheart, the show begins now.'' The blonde replied seductively and took his leg back to its place. Putting his hands straight on the ground parallel to his body with his palms lying flat on the ground, he raised both of his legs and slowly took them to place his feet near his head in backward direction.

The blonde looked at Jungkook with his face below his parted legs making Jungkook grow rock hard. he imagined how good it will feel to fuck the blonde in that position, he didn't try to hide his boner from the blonde who smirked again.

Coming back to the original position, He pulled down his track pants and throw it somewhere in the Gym.

''Hindrance....you know?'' he said innocently to the ravenette who nodded impressively seeing the black lace panties hiding that pink flower Jungkook loves to devour.

Turning to his right side, He raised his left leg and slowly took it behind his head and locked it there with his left arm. As his left leg was raised to lock behind his back, Taehyung's right leg lay straight on the ground opening the blonde for Jungkook to use him as he want.

The ravenette knew exactly what was Taehyung's plan so he was also playing along.

''You are asking for trouble, doll....I doubt you have recovered from the soreness from morning.'' Jungkook said smirking.

''What if I don't wanna recover, daddy?'' he asked innocently, but his actions were totally opposite. He unlocked his leg and came back to his position.

''Let me show you one more thing.'' Taehyung winked and went towards the steel pole that was supporting the pull up pole in the air.

Placing his one hand higher on the wall near the pole, he raised up his left leg parallel to the pole and locked it there. He looked at Jungkook with a suggestive smirk and it was the point where Jungkook decided to stand up.

Adjusting his track pants to accommodate his boner, he walked towards the blonde who was still standing in his position.

Eyeing the blonde from head to toe, Jungkook licked his lips. His hands went to slide down from the feet of the blonde that was in the air down to his inner thighs, his fingers just teasing Taehyung's wet opening a little.

The slight contact made Taehyung inhale sharply but he kept looking at the ravenette with the same seductiveness.

''You can't imagine what I want to do with your body, doll....'' Jungkook said huskily, his hands going upwards towards Taehyung's belly.

''And I wanna know what I can't imagine, daddy.'' Taehyung replied with the same want.

''I am afraid I will hurt you, princess.'' He said, pulling the sports bra down making Taehyung's tits to spill out of it. Jungkook bend down to blow on Taehyung's hard nipples.

''I want you to hurt me, Jungkook....ruin me, destroy me and m-make me a person....ah fuck...A p-person I was never before.'' Taehyung cursed when Jungkook blow a warm puff of air on his hardened nipple.

'' I want to pierce these beautiful nipples and make you wear my credentials in gold....'' Jungkook's finger rubbed around one of the nipple but he didn't touched it directly making Taehyung close his eyes in anticipation...''J'' The ravenette said moving towards the other nipple....''K''

Hearing the huskily said words, Taehyung felt himself getting more wet.

How sexy he will look with pierced nipples and wearing JK in gold....fuck!! The thought itself was a hard on.

'' A-And?'' The blonde asked biting his lower lip, his eyes now following Jungkook's eyes and hands.

''And...I wanna collar you....here'' The ravenette said cupping blonde's neck like a collar itself.

''And then....I wanna choke you...like this.'' The ravenette said putting a little pressure on Taehyung's neck cutting the oxygen supply but the blonde didn't felt any kind of panic inside him....he only felt excitement bubbling inside him.

''And?''

''And?....And I wanna play with that little clit of yours, torment it, assault it until you cry.... Your screams will be so satisfying...Fuck!!'' Jungkook cursed groaning as his cock screamed to be set free.

''I wanna scream, Jungkook...I w-wanna be your pet, follow y-your orders like y-your slut. I want you to f-fuck me like you h-hate me.'' Taehyung fought with his words as Jungkook's placed open mouthed kisses on blonde's breasts avoiding the aching hard nipples.

''You make me crazy, doll....See..'' He said pressing his hard on into Taehyung's lips between his legs. The blonde moaned shamelessly. He fought to stay in his position as his knees went gelly when Jungkook showed him how much Taehyung affect him.

''I wanna cum on your face, in your mouth....on these beautiful tits... on your pink delicious pussy.... Fuck!! I wanna mark you with my cum. I wanna cover you with my semen, doll.....'' The dirty words from Jungkook's mouth aroused a strange need of having Jungkook's cum all over his body. He moaned again with closed eyes.

The ravenette sat down on his knees, his hands placed on the inner thighs of Taehyung.

''I wanna fill every hole of your body with my seeds, princess...Put my baby in this sexy belly of yours.'' The ravenette kept talking in his one octave lower voice sending chills up Taehyung's spine.

''I can imagine you with that big baby bump. The world will know that its my baby inside you, that I impregnated you....that I claimed you, fucked you until you got pregnant.'' Jungkook's dark eyes twinkled with devilish insanity while Taehyung clenched around nothing hearing those words.

Carrying Jungkook's baby.....it sounded so hot yet so emotional to him.

''They will know that Jeon Jungkook is the one who was between your legs, making you scream and beg at the same time. I want them to know you belong to me, your soul belong to me...this body of yours, these tits, these delicious lips, this greedy pussy, this sexy ass.....all of it belong to me.'' Jungkook was not in his senses now.

The Devil inside him has took over his sanity.

Taehyung has tempted him to unleash his inner beast.

''J-Jungkook!!'' Taehyung moaned when ravenette removed the lacy panties to the side, his fingers founding the tiny bud. Rubbing circular motions slowly, Jungkook bite harshly on Taehyung's right inner thigh and sucked on it like he was drinking from the blonde.

''I wanna tie you up, make you miserable and fuck you so good....so good Tae that you wont be able to walk for days.'' The ravenette moved his gaze to look at the blonde who was already looking down at him with half hooded eyes.

''Like you said....I wanna use you, doll. I wanna get my pleasure from you not caring about your comfort. I wanna fuck you like I hate you....but I will not.'' Jungkook stood up, his hands cupping Taehyung's face with both of his hands while the blonde looked at Jungkook confusedly.

He want Jungkook to do what he just told him.

''W-Why?''

''Because I love you, princess....I will never hurt you.'' He said placing an open mouthed kiss on Taehyung's corner of lips.

''I love you too, Jungkook.....I l-love every side of you. I want you to show me your darker side. I love the beast inside you, Kookie... I fucking need you to feed on me. Fuck!!...I should have told you this earlier but I also wanna explore my darker sides.'' Taehyung said desperately.

Whatever Jungkook has said to him just now, it all has sounded so hot, so tempting that he wants Jungkook to show it to him.

He wants his body to look like how it looked in the Sauna. He wants Jungkook to take him to that high again.

''You can't imagine what this beast is capable of, doll...It can hurt you.''

''And I want to get hurt. Why the fuck can't you do what you said? Who the fuck are you to tell me about those dark fantasies of yours and then not show them to me? You motherfucking son pf a dinosaur...I fucking want you to rip me in half and then use me as your fuck toy!! I want your cum up my pussy, up my ass...I fucking want to drain you. I want to carry your child so give it to me like you fuck-'' The blonde was cut short by a feverish kiss when Jungkook captured his lips in a dominating kiss.

The ravenette pushed himself more into the blonde who was still standing in the same position with his leg raised over his head. The friction Jungkook's cock created against his sensitive clit sent jolts of electricity throughout Taehyung's body.

The Devil groaned and bite harshly on Taehyung's lips making it bleed. He sucked on it to draw more blood out of it. The Devil has never tasted such a delicious blood ever in his life except the one time when he had kissed Taehyung in the basement.

Jungkook picked up Taehyung who unlocked his position and wrapped his legs around Jungkook's torso as Jungkook walked towards the TRX straps hanging from the ceiling, still not breaking the kiss.

(These are TRX straps)

Both of them were needy with lust as their bodies fought to close every single inch of gap between their bodies.

Jungkook threw the blonde onto the couch and looked at him like a predator as Taehyung wiped his lips with the back of his hand, his eyes still screaming for more.

''Fuck Tae....now you will see my Devilish side.'' The ravenette groaned and pulled the straps to Taehyung's feet and tied them around blonde's both ankles taking care of the blood circulation.

Taehyung's both feet were tied, his legs wide apart with the straps up in the air while his upper body lied on the couch. The ravenette walked in between his legs and pulled Taehyung by his arm upto him.

The blonde immediately held Jungkook by his shoulders as ravenette's hard on teased Taehyung's opening.

''You love my beast...don't you?'' He asked pulling down the other set of straps used for double TRX wheelbarrow. The blonde nodded his head immediately as an strange excitement bubbled inside him.

''Then this beast will ruin you today and you know what strange this is?'' He asked taking one of Taehyung's wrist in his hand and tying it with the strap in same way as he has done with the ankles.

''W-What?'' The blonde asked looking at his tied hand. He couldn't figure what Jungkook was doing.

''Strange thing is that you will want more.'' The ravenette said now tying Taehyung's other wrist.

''Safe word?''

''Huh?''

''When you think you can't take it anymore, you says the safe word but remember...once you said the word aloud, everything stops.....listen carefully, every little thing. This fantasy will end as soon as you said that word.'' Jungkook explained him making Taehyung's throat go dry.

Can't take anymore? W-What does he mean by that? What I-is he going t-to do?

The blonde felt himself getting a little nervous.

''C'mon doll....tell me your safe word...something that you can remember.'' Jungkook asked him again still holding the tied blonde close to himself.

'' Umm.....R-Red?''

''Good....now enjoy.'' With that, Jungkook pulled his hands from Taehyung and helped him unwrap his legs and arms from Jungkook's body one by one...

As soon as both of them pulled away, the blonde lie flat in the air with his arms and legs wide apart in a starfish position.

''Any problem? any uncomfortable feeling due to the knots?'' Jungkook asked inspecting the knots around Taehyung's wrists and ankles once again.

''No''

''Good....Say the safe word when you feel like. Now close your eyes.'' Jungkook commanded.

''No...I wanna see.'' Taehyung protested making the Devil irritated.

''Its not about your wishes, slut....today is about my pleasure.'' Jungkook has totally lost himself to the Devil that was tempted by the sinful body and dirty words of the blonde.

''But I-''

''You talks a lot.'' The Devil groaned in anger and ripped the lacy black panty off the blonde. Coming around, he forced it into Taehyung's mouth gagging him with it.

''Close your eyes, doll.'' The Devil commanded again and this time, Taehyung didn't tried to protest. As much as he was panicked by sudden change in Jungkook, he was feeling a strange excitement between his legs too.

''You want me to use you....right?'' Jungkook asked pulling down his track pants and boxers at the same time freeing his monstrous cock who stood proudly between his legs.

Taehyung nodded his head immediately.

''Then fucking be my sextoy.'' Without any warning, the Devil thrusted into the blonde until his bottomed out. Taehyung screamed but his cries were muffled into his panties.

The ravenette pulled back and thrusted hardly once again and he groaned at the soft velvety walls that clutched his cock so perfectly. Tears run down Taehyung's eyes but he didn't dare to open them.

''I will fuck you like you wanted me to, doll...'' He pulled back again and thrusted again, his each thrust getting deeper than the previous one.

Taehyung clutched the strap tied around his wrists tightly. It was hurting but he didn't wanted it to stop.

Jungkook hold the blonde by his waist and started thrusting at an animalistic pace, his sweaty body getting more wet with sweat as he worked on to quench Taehyung's thirst.

The blonde felt Jungkook hitting his cervix. The pain subsided and it turned into heavenly pleasure. His screams turned into moans and his pussy started getting more greedy.

It wanted more.

It wanted Jungkook to fill it up with his seeds like he had promised.

''You were made for me, doll....fuck!!, Look at you, taking me so good, yet you want m-more.'' He pinched the clit at the end of his sentence making Taehyung scream in pleasure.

''So tight...so wet, so so-soft.'' the ravenette kept ramming into the blonde who was suspended in the air. Jungkook's eyes twinkled when he saw Taehyung's tits spilled out of black sports bra were now bouncing with his every thirst.

His hand went to slap it harshly making blonde scream in pleasure again. The ravenette's fingers imprinted on the white skin of the blonde and it tempted to slap his other breast too.
