Six months later and Lu and Balthazar were still going strong. Many other dates had ensued, outings with friends and dinner at home. Lu had brought toys over to play with as promised and they played with them and each other, a lot.

Today had started off with Balthazar's tongue in and around Lu's ass but just as his orgasm was beginning to build, Balthazar inserted one of their medium sized butt plugs into Lu, slapped his ass and got up to get dressed.

Lu choked on his moan and turned around on all fours slightly confused and extremely turned on.

"Don't worry, love, you'll get to have your orgasm later, we don't want to be late for work. So no touching."

Lu almost growled as he got off of the bed and got some clean underwear from his bag. He dressed and followed his boyfriend to the kitchen.

In the car he told Balthazar "This is bad for kid's education you know, I can hardly think beyond the need for you to fuck me into something. How am I supposed to do mathematical equations?"

Balthazar laughed and took his hand from Lu's knee and cupped his bulge. Lu's head hit the head rest, back arching as he pushed into the touch and moaned.

The French teacher took his hand away and put it back on the wheel. "I actually didn't expect you to still be that hard."

"I'm quite sensitive at the moment, so every time I move, it causes rather pleasant sensations. Just for your information." Lu informed him.

"If it's too much you can take it out and-" Balthazar began worrying that maybe their game had gone too far.

"Oh, no, I didn't mean to make you worry, I'm just playing the game and seeing if I can make you break and fuck me now instead of whenever you're planning to." Lu assured him as they pulled up in the parking lot. "Trust me, I'm okay, I promise."

"Okay, well I'm not going to break, so I'll see you later love." They kissed and went their separate ways, Balthy needing to go to the library before class.

It was so hard to concentrate on teaching and Balthazar had left him so wet and slick that the plug moved slightly when he walked causing him to leak the wetness. His hard on had lessened a bit, but he was still so turned on and sitting just pushed the plug further into him.

Lu was so relieved when the lunch bell rang, he just leant against his desk for a few minutes trying to keep it together when Balthazar opened the door, closed and locked it behind him and strode up to Lu.

"Hey..." Lu greeted.

"Hi love," He came up behind Lu and wiggled the plug with his hand through Lu's pants. The Math teacher moaned. "how are you feeling? Ready to be fucked over your own desk?"

Lu's hips bucked as Balthazar spoke and he groaned "Ah, please, Balthazar please." He knew he sounded so god-damn needy but he couldn't bring himself to care right now.

He opened Lu's pants and pulled both his pants and underwear down to mid thigh. Lu heard a condom wrapper rip open and then it was being rolled onto his length.

"We don't want you to ruin your desk." Balthy answered the unasked question.

Balthazar opened and pulled down his own pants and slapped Lu's ass so hard it left a hand print. The younger man let out a yelp.

"You're going to have to be quiet love, unless you want to get caught."

"I'll be quiet, please just fuck me already."

Balthazar obliged. He slowly dragged out the plug and put it aside, watching Lu twitch and tremble as he slid straight into the wet heat. Lu's arms almost gave out and they both gasped.

Balthazar started with slow drags in and out and Lu thought he was going to lose his mind. He eventually quickened the pace and aimed for Lu's little bundle of nerves, which judging by the younger man's moans he hit the target every second or third time.

"Balth-I-please Oh, fuck, mmmnn... Touch me!"

"No, you're going to come for me like this." Balthazar tried to sound like he was giving orders, but he was trying to fight his building orgasm.

Balthazar continued to thrust into him, but he moved closer, so their bodies were against each other. He pulled Lu's collar down and bit down hard on Lu's shoulder while his other hand slid under his shirt and scraped his nails down his boyfriend's chest.

Lu's body shuddered and he screamed silently, knuckles going white from the tight grip on the desk as he filled the condom with his seed.

Balthazar only lasted another few thrusts before coming deeply inside his boyfriend. The slumped over the desk panting for a few moments.

The French teacher recovered first and cleaned Lu up as much as he could in a classroom. He fixed up their clothes and that's when he noticed the big red bite mark that had little specks of blood dotted through it.

"Oh my god, Lu, are you okay? I'm sorry I didn't mean to make you bleed."

"Hmm? I am wonderful. Actually you are wonderful. That was hot as fuck. Please don't be sorry, I just had one of the best orgasms of my life." He stood up straight on jelly legs and held Balthazar in his arms. "Balthy, I love you, and trust me when I say that I trust you completely to hurt me in all the right ways."

Balthazar was a bit stunned "I do trust you but...hang on, you love me?"

Lu smiled "Yes, I love you, Balthazar Roche."

The French teacher grinned "Good, because I love you too, Lucifer, even if you are the devil."

They laughed and kissed even as the bell rang to signal that lunch had come to an end.
