Even when the Heat starts.

Mating time?

(Warning mature context ahead!😎 this is a longer chapter)

Jimin cursed under his breath, his groin hardening as he pulled Yoongi up, smashing their lips together with a growl he then pulled away. "I'm here" he said, pushing Yoongi back on the floor, straddling him as he grinded down on him. "I've got you.." he mumbled, pulling at Yoongi's hair. Yoongi moans through his tears while he kisses him back. He felt so needy, but in pain at the same time. "J-Jimin ah please! H-help me.." Yoongi felt something in him, he weakly raises his arms as he puts them around Jimin's neck. He shivers in need for Jimin, but couldn't bring himself to say it.
Jimin growled low in his throat as he pushed himself against Yoongi. "Help? What do you need?" He asked, faking innocence. He pressed his thigh in between Yoongi's legs, his fingers pulling at his hair harder than before. "Ahh! W-Wait! That hurts Jimin!" Yoongi says as he places a hand on Jimin's hand that was in his hair, he moans in pleasure as he feels Jimin grind against him.
"Shit.. sorry. I got ahead of myself.. sorry" he mumbled, pressing his lips to Yoongi's neck in apology. "What do you want me to do?" Yoongi then says in a confident tone, "make me feel no pain! I can't help wanting you!" Yoongi said as he was moving his head to the side to give Jimin more access to his neck. "I need you Jimin, please I don't know why my body is calling for you but it m-must be a sign so p-please help me!"
Jimin nipped at his neck with his teeth, moaning quietly. "You want to mate with me?" He asked, wanting Yoongi to answer before he did anything. "Y-Yes! I would even take your p-pups!" Yoongi covered his mouth as he let his thought of pups slip out. He mentally smacked himself, he knew only rare breeds could have pups. He blushes and suddenly groans in pain as he feels his member become harder in his pants. He felt Jimin's member and knew he shouldn't be thinking anything that would get him in trouble so he flips their positions to where Yoongi was face level with Jimin's lower regions. He unzips Jimins pants and pulls his member out, he licks it teasingly and starts to suck slowly. Yoongi realized what he was doing and pulled back "I'm so sorry! My instincts took over... I'm so sorry.."
Jimins heart fluttered at Yoongi's words. "pups.." he mumbled, gasping at what Yoongi had done he began groaning when Yoongi had pulled his painfully hard member out. His head fell back and he moaned loudly, bucking his hips up. His eyes widened when Yoongi moved away. "No... Stop being so shy, Yoongi" he demanded. "I'm your mate, don't hold back around me. Do what you want" he told him.
Yoongi's body moves on its own due to Jimin's demand, he then went back to sucking. He bites down lightly teasing Jimin a little as he goes back to sucking only to go at a fast pace, his body not letting him up until he is told to. Yoongi moans sending some vibrations, he knew Jimin was close by the twitching so he went faster and sucked harder. "Mmmm" Jimin stopped him, pulling him away before he came. "Close... That was really close. You're so good, but I want you to lay down" he said, stroking himself as he took his pants off.
Yoongi lays down as told, he was out of breath he then felt sweat drip down his forehead. "Y-Yes of course Alpha!" Yoongi felt a blush rise to his face and covers it, he felt embarrassed. Jimin slowly moves to top Yoongi, pulling his hands away from his face. "Don't be shy, you're mine now. I'll take care of you" he said, attaching his lips to Yoongi's neck as he palmed him.
Yoongi jumps at the contact, he was releasing moans as he felt Jimin's hand move. He had never felt this kind of pleasure before, he moves his face to the side to give Jimin more access to his neck. A wave of pain suddenly hit him, he quickly shut his eyes and winced. "You need me to hurry?" Jimin panted, pressing himself down on Yoongi as he began to leave lovebites on his neck.
Yoongi felt the surge of pleasure and pain while Jimin leaves little lovebites on him. He felt relieved as well as safe now, he couldn't put it into words but his strong scent minimized and was now begining to mix with Jimin's. Now no other alphas will mess with him, and even if they do Jimin would know about it. "A-Alpha please... Don't tease me a-anymore!" With tears streaming down his face, Yoongi felt his member twitch while getting harder and more painful. He looked up at Jimin with pleading eyes that are begging for him, he leans up and licks Jimin's neck lightly leaving kisses. "Shit" he cursed, pulling Yoongi's shirt off as he frantically kissed down his chest. "You want me to prep you?" He asked, his eyes glowing red as he felt their scents mixing. Yoongi was his, and only his. He unbuttoned Yoongi's pants, pressing his tongue flat agaisnt him through his boxers.
Yoongi moans out a yes, but quickly bucks his hips up at the contact of Jimin's tongue. He squirms a little, he was so new to this and he was afraid that Jimin wouldn't like his body. "P-Please alpha! I-I need you" Jimin pulled his boxers down, biting his lip. "You're so goddamn beautiful" he mumbled, running his hands up and down Yoongi's chest as he kissed his thighs. "I don't.. I don't have lube or anything" he muttered.
Yoongi was embarrassed to do this but he pointed at the closet, he looks away with a huge blush on his face. "Sometimes I would do things to m-myself during my heat, but it w-wouldn't work. It's in a blue box on the top shelf, don't mind the t-toys in the b-box please.." Yoongi had wished he hadn't said anything, because it clicked in his head that he said toys. He groaned, feeling himself harden at the thought of Yoongi playing with himself. "Okay" he mumbled, scrambling to get the box in his closet. He smirked at the assortment of toys in Yoongi's box. He got the lube, pulling Yoongi's pants down impatiently and smiling at him. "I've got you" he reassured. "You won't be hurting for long"
Yoongi nods in response, he turned himself over to give Jimin more access. He begins to wiggle his butt trying to get comfortable, he had no idea what it was doing to Jimin and  he finally got in a comfortable position a pain hit his body. He breaths for air, he knew someone was watching them based on his feeling. He started to shake, while tears slip out. "Hey.. what's wrong" he asked, his middle throbbing at watching Yoongi move around like that. He was painfully hard, biting his lip as all other senses were drowned by Yoongi's scent.
"I-It's nothing I'm just n-needing you inside me.." Yoongi turns and looks at Jimin with a certain look in his eyes. This time he shakes his butt on purpose, but pretending to be innocent. Jimin bit his lip, pulling Yoongi up on his knees so he had a better angle. He poured lube onto his fingers, pressing a finger into the tight rim of muscles. Yoongi jumps and groans at the feeling of Jimin's fingers inside him. He squirms a little to get used faster but it had the opposite affect, he tries pulling away. "It h-hurts!"
"I know... It's gonna hurt. Don't move too much, it'll get better. I'm sorry... Im just trying to hurry for you" he muttered, holding Yoongi's hips so he couldn't move away. Yoongi nods, he closes his eyes while moaning as the feeling did get better. "A-Alpha I'm close!" Yoongi was loving the feeling of Jimin's fingers he had did this to himself but immediately stopped due to the pain, but for some reason the pain went away as soon as Jimin said it would. He squirms in pleasure now, not in pain. Jimin immediately pulled his fingers out. "I'll make you feel good.. are you ready?" He asked, rubbing Yoongi's back. His eyes were staying red now, being so close to mating with Yoongi allowing his instincts to take over.
Yoongi nods in response, he knew what was happening. He was so anxious to know the feeling of Jimin being inside him. "Y-yes! Please A-Alpha!" Jimin poured lube on his painfully hard member, pumping himself a few times before turning Yoongi over. "Gotta see you" he mumbled, lining himself up as he started to push past the ring of muscles with a groan.
Yoongi's eyes begin to tear up, he felt his back arch while he covers his mouth screaming. He closed his eyes super tight, tears falling while his eyes shut. "IT HURTS! A-ALPHA!" "Sorry... Sorry Yoongi" he mumbled, stopping his movements. "I'm sorry.. it's gonna hurt. Just.. tell me when, I'm sorry I don't mean to hurt you" "I-It's okay... Just let your instincts out alpha! I'll be fine, b-besides I-It will get better!" Yoongi smiles with tears flowing down his face as he touches Jimin's cheek while rubbing lightly. He smiles his gummy smile and leans up kissing Jimin's lips lightly.
Jimin frowned, his eyes flashing from brown to red. "I don't want to hurt you" he insisted, groaning as he fought the urge to continue pushing himself in farther, his head screaming at him to thrust into Yoongi's tight heat.
