True to his word, Yoongi had kept Namjoon tied up with the large dildo halfway down his throat for the entire six hours.

"Almost forgot you were here," Yoongi chuckled as he untied Namjoon at ten to 4. "You're so much more tolerable when you're forced to be silent."

Namjoon glared, waiting for Yoongi to finally take the tape off so he could spit the gag out.

Yoongi took his time, slowly untying the boys legs and torso, and piling the ropes up neatly back in their box.

He saw the soft red marks all over the students pretty tan skin, and ran his fingers over them, massaging the sore areas. "I have a special cream I could apply for you for this, it's made exactly to help with rope burn like this." He murmured. "But it's gunna be 4 soon, so it's up to you to decide if you want that or not."

Namjoon still couldn't answer with the tape over his mouth and although his hands itched to rip it off, it wasn't 4 just yet and he couldn't.

He kept his hands in his lap, rage burning just below the surface.

Yoongi finally turned his attention to the boys face. He smiled at Namjoon's angry expression with a soft laugh.

He cupped the boys face, stroking his thumbs over the tape. "I hate having to cover up your dimples, sub. But you didn't give me a choice. You need to be trained."

Namjoon blinked slowly, just wanting the fucking fake cock out of his mouth already.

Yoongi carefully, slowly, peeled the tape off the boys cheeks, and off the end of the toy, and before Namjoon could spit out the gag like he wanted to, Yoongi held up a finger to stop him.

"Let dom do it." He warned in a low voice.

With it not being 4 just yet, Namjoon had to obey.

Yoongi raised his hand and grabbed the base of the large toy, but instead of pulling it out, he went the opposite way, pushing it in deeper and Namjoon choked, his hands shooting up to stop him, and Yoongi stopped him with his free hand, grabbing the students wrists and forcing them back to the boys lap.

"Stop." He commanded, eyes narrowed. "Relax your throat, sub. I'm not going to hurt you, Namjoon."

Breathing heavily through his nose, Namjoon forced himself to listen, closing his eyes as the toy triggered his gag reflex and tears sprung to his eyes.

Yoongi slowly dragged the toy up, over the students tongue, and then pushed it back down, gradually speeding up until he was throat fucking the student with the toy.

Namjoon was able to keep up with it for a little while, until he suddenly tightened up his muscles and choked over the toy, panicking and pushing Yoongi away.

Yoongi sighed as he stood up to clean the dildo. "Well, it's still progress, sub. We'll get rid of that gag reflex soon enough."

Namjoon coughed and wiped his mouth with the back of his hand.

After having that huge cock down his throat for six hours straight, he felt empty when Yoongi took it away.

Not that he would ever admit that to the pervert, though.

And same with the heavy ropes. With them gone, Namjoon felt too weightless and a little cold.

He stood up, sighing when he was finally able to stretch his legs and ran his palms up and down his thighs vigorously to return the blood flow.

Yoongi watched. "I can help you with that, sub. Did you want the cream?"

Namjoon scowled, just wanting to jerk off. "No."

He hated the way his voice was scratchy and rough from the toy.

But he couldn't come. Not without Yoongi's permission anyway.

He knew Yoongi would probably let him come if he begged and humiliated himself, but Namjoon wasn't that desperate. He would just take a cold shower when he got home.

Their watches went off, signaling the end of the session and Namjoon jumped to his feet, snatching his clothes up and yanking them on.

Yoongi watched with a smile, following the student back down the stairs, where Namjoon slid his shoes on and threw the door open.

"See you tomorrow, sub." Yoongi cooed.

Namjoon flipped him off with a snarl, and then the door slammed shut.

Yoongi chuckled, pulling out his phone to text Seokjin.

Sure they couldn't have a session, but they could still call, and Yoongi missed the pretty switch already.

And there wasn't anything in the contract saying that I couldn't ask for some ideas to help with taming Namjoon, Yoongi thought with a smirk, dialing his friend.

Yoongi had absolutely no intention of losing the bet.

None.
