"Just hurry up and get it over with."

Namjoon flopped onto the bed with a grumble, just wanting Yoongi to switch the plugs quickly so he could lay down and do nothing for the the rest of the hour.

Yoongi sighed as he picked up the case, opening it to reveal the red and blue plugs they had used already, and the missing green one that was still inside the sub.

The next one was yellow and he plucked it out from its velvet spot.

"It's no fun unless you fight me on it." Yoongi teased.

"Who says I care if you have fun or not, pervert?" Namjoon snapped.

"I always have fun with you, sub." Yoongi's tone implied a different kind of fun, and Namjoon shut up.

Yoongi climbed onto the bed and grabbed the lube while Namjoon kicked his pants and boxers off.

"Shirt too." The dom said.

Namjoon scowled. "Why."

"Because I like looking at whats mine." Yoongi replied as he slicked up the plug.

Namjoon glared, cheeks turning red. "I'm not yours, asshole!"

"You're mine for the month, sub." Yoongi reminded him.

Arguing under his breath about technicalities, Namjoon slid his shirt off and crossed his arms over his chest to hide himself from Yoongi's eyes.

Yoongi just smiled at his cute sub. "Flip over, baby."

Namjoon did, huffing like Yoongi was asking so much of him.

Yoongi grabbed the base of the green one, remembering last night.

"Hurry. Up. Pervert." Namjoon muttered, muffled as his face was buried in the pillow.

Yoongi smiled, patting the students round ass. "Just marveling at how beautiful my sub is."

Namjoon was silent, and Yoongi knew the boy was trying to hide his blush, too embarrassed to come up with a comeback.

He tugged on the end of the plug, gently.

"Relax, baby." He murmured. "It'll be easier to pull out if you're loose."

Namjoon grunted, but forced himself to relax.

Yoongi twisted the plug a few times, pouring some lube over the boys hole as he slowly worked the toy out.

"Ah, fuck, asshole!" Namjoon cried as his rim was stretched around the widest part, then groaned in relief when the toy was finally removed.

Yoongi rubbed the boys back comfortingly while Namjoon caught his breath.

"Good boy," Yoongi leaned down to kiss Namjoon's shoulder. "Always so strong for dom."

"Whatever, pervert."

Yoongi chuckled. "Remember last night?"

Namjoon did, and he kept his face hidden in the pillow. "Yeah. So?"

"Dom said you get a reward today." Yoongi hummed, placing the green plug in a bin to be washed later. "And you get to decide what that is."

Namjoon perked up at that.

"Anything?" He asked, mind already miles ahead.

"Almost anything." Yoongi said. He picked up the yellow plug and lined it up with the boys hole. "Relax, baby."

Namjoon did, lost in thought about his reward, and Yoongi slowly worked in the second biggest plug.

Namjoon huffed at the stretch, fingernails digging into the blankets beneath him, groaning when the toy popped into place.

"Fuck, why don't you shove your whole fist in next time?" He complained.

"Because lucky for you, I'm not into anal fisting, or else I would." Yoongi replied, patting the boys ass. "Do you know yet what you want for your reward, baby?"

"Does this one vibrate too?" Namjoon demanded to know. "Or inflate?"

Yoongi chuckled. "No, only the green one had its little trick."

Namjoon didn't believe him.

"I promise, sub. This plug and the next one don't do anything." Yoongi said.

"Next one is the last one?" Namjoon sounded hopeful.

"Yes, baby. Then we're done with stretching." Yoongi said. He climbed off the bed. "I'm going to wash some toys, let me know when you decide what you want for your reward."

Namjoon sat up. "I know already."

"Are you going to tell dom?" Yoongi picked up the dirty bin.

Namjoon shook his head.

Yoongi chuckled. "Okay, baby."

Namjoon puffed out his cheeks when Yoongi didn't seem to be bothered by Namjoon keeping him in the dark.

He watched Yoongi leave the room and stood up, wincing at the new weight in his ass.

"I better go back to normal size after this!" Namjoon shouted after the little dom.

There was no reply, typical Yoongi, and Namjoon huffed in annoyance.

He pulled his clothes back on, a little awkwardly with the new plug, and padded down the hallway.

He wondered what was next, since Yoongi never did just one thing in a session, and he wanted to be prepared for it.

So he was surprised to see the dom sitting on the couch, flipping through the TV.

"Hey!" Namjoon demanded, crossing his arms.

"Sub." Yoongi didn't look at him as he switched the channels.

"What are you doing? We still have forty minutes left!" Namjoon walked over.

"Jealous I'm paying more attention to the TV than to you?" Yoongi smirked, patting the cushion beside him.

Namjoon frowned, wondering if this was a trick, since he wasn't allowed on furniture.

Yoongi seemed to read his mind at the students hesitancy.

"Good boy, knowing your place isn't on my good furniture." He cooed. "But I'm allowing you today, since you were a good boy for dom."

Namjoon glared. "You're a fucking asshole."

"Don't push it, sub."

Namjoon sat down, pretending the plug wasn't shoved up against his prostate at the action, pulling his feet up on the cushion in hopes of annoying the dom.

But Yoongi looked passive as he flicked through the channels.

"I want that massage." Namjoon complained loudly a few minutes later. "You said you would give me one ages ago."

"Is that what you want for your reward?" Yoongi didn't take his mind off the screen.

"No. You said you would give me one if u wanted, and I want it now." Namjoon crossed his arms, daring Yoongi to say no.

Yoongi propped his legs up on the table in front of the couch. He patted his lap and Namjoon balked.

"Lay down." Yoongi instructed.

Namjoon did, after debating if the massage was worth it. He decided it was, since it would take up the rest of their time together, and laying down was always his favorite position when he had a plug in, since it took the weight off.

He settled his torso over Yoongi's warm thighs, grabbing a pillow and resting his cheek on top of it as he watched the show on the TV.

Yoongi grabbed the boys shirt and pushed it up to the boys shoulders, revealing his bare back. He admired the students blemish free skin, running his hands over it softly. He hummed, pressing his palms down, feeling the knots in the boys muscles.

"You have a lot of tension, baby." He murmured as he worked them out one by one.

Namjoon bit back a moan at the feeling of Yoongi's fingers working on his back.

"If you ever want dom to help you relax like this, just ask." Yoongi said. "I'll always say yes."

Namjoon knew he should say thank you, but he didn't like Yoongi so he ignored the dom.

Yoongi hummed as he worked, starting at Namjoon's shoulders and working his way down to the dimples at the base of Namjoon's back.

Namjoon squirmed when Yoongi's fingers got close to his ribs.

"Watch it, asshole." He muttered, feeling sleepy as the dom eased his stressed muscles.

Yoongi smirked. "Ticklish, baby?"

"Try it and you'll get kicked the fuck out." Namjoon warned.

Yoongi chuckled, bending down to kiss the boys back. He rubbed the spot over when he straightened up.

Namjoon tried to focus on the show, but between Yoongi's body heat, the comfy pillow, and the dom's familiar cologne scent, he found himself drifting off.

Yoongi continued his massage even after Namjoon fell asleep on his lap, knowing the student needed his rest. He wished they had made the bet for two hours, just so Namjoon could sleep for the last hour before having to go home and do all his school work.

It startled both of them when their watches suddenly went off, signaling the end of their hour together.

Namjoon huffed, forcing his eyes open.

He didn't want to get up yet. Getting up meant jostling the plug and having to sit down as he drove home, and then at home he would have to do his homework and deal with his parents.

Yoongi kissed the boys shoulder, before pulling Namjoon's shirt back down. He patted the boys ass softly, signaling him to get up.

Namjoon grudgingly did, annoyed instantly when he felt the plug again. He got to his feet and stretched, surprised at how good he felt.

"You had a lot of knots." Yoongi said, getting up as well. "You should get them worked out at least once a week."

"Whatever." Namjoon pretended like he didn't enjoy the idea of Yoongi giving him a massage once a week.

He slipped his shoes and jacket on, excited that tomorrow was the last day for stretching, and then he would be done with these stupid plugs.

Yoongi walked him to the door.

"Are you ever going to tell me what you want for your reward?" He asked as the student got ready to head home.

Namjoon smirked.

"Yeah, actually."

Yoongi smiled. "What is it, sub?"

"I want to fuck you."
