CHAPTER 86: A PROMISE IS A PROMISE! 5 [18+]

Lucien’s cock twitched hard as Rin said those words to him. His cheek flushed red, and his face, which was filled with confusion, turned slightly as he peeped at Rin’s lewd face.

Maybe that word came out as a mistake but no... Even if his words couldn’t say it, his expression sure did.

"Rin, you know how much I’d love to fuck you," Lucien said, his hand rubbing Rin’s bare ass. "However, you’ll have to do as I say,"

"Isn’t that unfair? Are you trying to turn me into your slave because of this weird situation?"

"Well... yes. But... not yet," Lucien averted his gaze and Rin frowned hard.

He didn’t want to comply with Lucien’s wishes. It would seem as though he has given Lucien power over him. But, again! His fucking body wanted it. His body wanted Lucien to carve his mark and name over his body and thrust into his tight hole till it stretched to the size of his massive weapon.

"Fine, do as you want," Rin said and a grin appeared on Lucien’s face. That same grin Rin didn’t want to see.

"Raise your bottom, Rin," Lucien ordered.

Rin felt his lifespan reducing and without asking any question, he obeyed, lifting his arse up, his hole visible to Lucien. It was dripping wet from Lucien’s saliva and pink, just like his nipples.

"Hmm... I can’t believe your inside could look this slutty, Rin..."

"Have... Have you gone insane? Do you have to say that out loud?" Rin buried his flushed face into the pillow.

He tried to think about it again. Maybe it’s not a good thing for him to get dicked by Lucien fucking Vortellion... But he was hungry for it and even something more.

"My bad! I must have made a grave mistake feasting my eyes on what’s open before me," His lips curved into a smirk.

Lucien slipped two fingers in his mouth, soaking them with saliva before sliding them inside him, scissoring his insides and touching him everywhere.

Rin squeezed the pillow, letting out a muffled moan. His toes curled as his back shook up and down.

"Hng..." He moaned into the pillow.

"You’re so tight, Rin,"

"Shut up! That’s because no dick has been in there before," Rin yelled and Lucien froze when he remembered his father. Rin must think it’s his first time, but Lucien knew it was not. He wanted to make things easier for Rin so he won’t bleed like when his father thrust into him like the hungry perverted monster that he was.

Well, it wasn’t his fault. Rin was cute and seductively charming. He would have thought someone like Rin had tons of lovers. After all, most Omegas use their beauty to attract people since the world is unfair to them.

However, Rin wasn’t like that. He was different and the fact that he wasn’t the one taking Rin’s first time made him angry.

’Maybe I should have killed that Evan fucking Vortellion,’

He thought to himself, till Rin’s voice penetrated his ear.

"You bastard! You’re going too deep! You’re not trying to kill me, are you?" Rin asked, turning his head to look at Lucien.

Lucien looked at his fingers that were deeply buried inside Rin. He twisted his fingers as he tried to pull them out and it made Rin moan even harder.

Rin clenched his fingers around the pillow, while Lucien’s fingers danced balletically inside his hole. It thrust, spread and circled his inside. Isn’t that what ballet is like? Maybe not.

But he was enjoying it. Even if Lucien was going too deep, ’accidentally’ hitting his sensitive spots.

He fucking loved it.

He was enjoying it... enjoying it so much that it was weird. Actual moans were coming from his mouth.

’I just hope at this rate... I won’t fall for this student because of his pleasurable skills. There’s no way something like that could ever happen, right?’ He thought to himself.

"I hope you’ll brace yourself for this, Rin..." Lucien’s voice snapped him out of his thoughts. His eyes grew wider as another finger slipped in.

"Wait! Wait! Wait! A third finger? It’s too much! Why did you shove it in?"

"I already informed you before I did, baby lamb."

"Fuck! It won’t fit! Take it out!" Rin arched his back lower and raised his arse higher.

"That’s what you keep saying but... If it won’t fit, how do you expect my dick to fit inside you?" Lucien asked. "Can’t you see the way my fingers are sliding in and out?"

Rin fell silent. He could only moan and groan. Lucien’s fingers went deeper, feeling the warmth of his insides. Rin clenched his walls repeatedly almost snapping his fingers into two and he finally stopped twitching. His back trembled as if Lucien had hit his weak spot inside him.

"You’re finally wet for me..." Lucien took his fingers out, staring at his wet fingers. It was soaked with Rin’s juice. His eyes glittered as he held the urge to lick his fingers.

Rin would probably call him disgusting again.

"Please, put it inside already" Rin begged, wiggling his arse over Lucien’s hardened cock.

"Fine, I’ll give you what you’ve been asking for,"

Lucien wrapped his soaked fingers around his cock before rubbing it with Rin’s juice.

He dragged himself by his knee closer to Rin before he drummed his dick on Rin’s entrance.

"I’m going in now,"

"Thanks for the announcement," Rin said, holding both the bedsheet and pillow tight. It’s going to be his first time having a dick sliding into him and he was nervous. It was going to be his first sex in both worlds. It’s like he’s giving up his virginity to a man.

And also... He felt like he was forgetting something but...

’I’ll try to remember later. For now, let me focus on Lucien’s cock,’

Lucien grabbed Rin’s butt cheek with one hand, spreading it open before slowly letting in an inch of his crown inside.

It slipped in easily. Widening his legs and biting his swollen bottom lip, Rin waited as Lucien’s dick thrust inch by inch till his insides were filled up.

"Fuck! You’re so huge" he grunted.

"Thanks for the compliment, babe" Lucien grinned. He saw that Rin wasn’t bleeding which was a huge relief for him. That meant he could go all out and give Rin the best sex experience and a reason to crave his cock even more.

He slowly slid his cock out till just an inch was left inside Rin and immediately, he thrust back in with full force.

"Mhhmmmn... Fuuccckkk!!!" Rin raised his head and moved his legs, but Lucien pressed his upper body down to the bed and continued to thrust slowly but hard.

Thrust. Thrust. Thrust.

Lucien clenched his jaw, slapping Rin’s arse cheek. His insides were squeezing him so tight, almost snapping his cock in two.

"Fuck!" Rin whispered. "Fuck! Fuck! Fuck!"

Lucien buried his chin on Rin’s shoulder, as his hand lingered on his chest, pinching his hardened nipples. He was sad that he couldn’t see what kind of face Rin was making.

"Did I hurt you?" He asked.

"No" Rin answered into the pillow. "It’s... It’s good,"

"Good. Then, I’ll go faster"
