This is a commission!

-

Poor little Mammon – too stupid to figure out that putting on this desperate display of arrogance and defiance was only making him more excited. Though, he supposed he shouldn’t be surprised. This was the same idiot who decided it be a good idea to, once again, disobey him and kiss that damned mortal. Did he think that he wouldn’t see him? That one of his many, many spies wouldn’t report this insult back to him? Such a foolish child. While he had been furious – as was his right as Mammon’s brother and owner – he was more concerned for this pitiful boy. He could turn a blind eye to most transgressions or respond to the more severe actions with a slap on the wrist and a stern lecture but this…this was something he could not allow to pass. Upon witnessing this foolish child so stupidly kiss that mortal, Lucifer know he could no longer stand by. A punishment was in order to teach Mammon just who he belonged to, and how worthless and useless a fight it was to try to wriggle free from his grip.

Lazily rolling his hips, keeping his cock buried deep inside of Mammon’s tight, hot hole, Lucifer played with his adorable nipples with one hand while the other relentlessly jerked him off. A continuous flood of precum poured out of the slit. Both his penis and nipples were flushed bright red, swollen from his constant assault. Underneath him, Mammon was a writhing mess of stifled moans and trembling limbs. He was still trying so hard to hide how good he was feeling. Lucifer glanced over at the elaborate clock in the corner. The corner of his lips curled up into a slight smirk. Really, he was impressed. Seven hours of this and Mammon, his cute little brother, was still clinging to this pathetic defiance. It was so much less than the fight he had been putting up when they first started. The snarling insults, the vicious struggle against the unbreakable binds hold him, the burn of rage and heat blazing in his beautiful eyes – Lucifer almost missed it. It had been so fun and satisfying to watch him slowly lose steam, slowly break down as the pleasure wore away at him.

Lucifer’s gaze flickered back to Mammon’s brightly flushed, sweaty face. A pronounced haze was beginning to dominate Mammon’s beautiful eyes. He was having a harder time holding back his moans. It wouldn’t be much longer now. What was left of his resolve was being crushed underneath the screeching need for relief. Not once during the seven hours they had been doing this had Mammon been allowed to cum once. Wrapped around the base of his swollen, bright red penis was a thick strand of leather, enchanted with a spell that kept him right on that excruciating brink, a second away from cumming but unable to. It would only release with Lucifer’s command but he had no plans on giving his beautiful little brother any relief until he did as he was told. Lucifer rubbed the pad of his thumb against the tip of Mammon’s cock, earning himself a squealing wail. His grin widened further. While he could easily use his sway over his adorable brother, he wanted him to submit on his own merit.

He wanted Mammon to realize that there was no escape from him and, with that realization, submit without complaint; submit with a breathy plea to show mercy; submit with a promise that he would never disobey him again.

“Lu…Lucifer-!” Mammon choked out. Tears streaked down his flushed cheeks. Panting heavily, his chest heaving with every labored breath, Mammon forced out through clenched teeth, “Please-! Enough! My penis! It hurts-! It hurts-! My penis will break!”

Lucifer just smiled, sliding his hand up to rub his palm firmly against the tip. Throwing his head back, a powerful shudder wracking his muscular body, Mammon screamed shrilly. His insides clamped down even tighter around Lucifer’s cock. Laughing low in his throat, Lucifer bent down to drag his tongue across the nipple he wasn’t torturing before pushing up further. Trailing a line of wet kiss along the sharp line of Mammon’s jaw, he brought his lips to his ears and murmured, “I’ve told you what you must do if you want release so be a good boy and obey.”

“You-!”

Changing the position of his thrusts ever so slightly, Lucifer abruptly ramped up the pace, slamming into Mammon with enough strength to send him jolting upwards. Pleasure rolled in thick, heavy waves through his body as Mammon’s hole squeezed and stroked his cock. Wailing at the top of his lungs, his teeth clenched tightly together, eyes crossed and rolled back, Mammon endured only a few moments of those brutal thrusts before, finally, he squealed out the words that Lucifer had been waiting for.

“Please-! Please-! Lucifer-! Cum-! Cum-! Please let me cum! I wanna cum! I wanna cum! Please-! Please-!”

“Come now.” Lucifer laughed, kissing the corner of Mammon’s mouth, “You can do better than that.”

Panting harshly, a divine expression of absolute desperation on his flushed face, Mammon false started a couple times before howling, “Please-! Big brother-! Big brother-! I’m sorry-! I’m sorry-! Please-! Forgive me-! Forgive me-! Please-! It hurts, big brother-!”

“Almost there.” Lucifer breathed, a violent spark of excitement blazing in his dark eyes. Straightening up, he said, “Will you ever disobey me again?”

“No-!”

“To whom do you belong?”

“You-!” Mammon wailed sharply, “You-! You-! I belong to you, big brother, so please-!”

“That’s right…” Lucifer grinned demonically, leaning down to press his lips to Mammon’s, “You are mine, Mammon. This body, this hole, your heart, your soul – every drip of sweat, every tear, every breath belongs to me. Don’t ever forget that or I’ll show you just how cruel I can be. Do you hear me, Mammon?”

“Yes…” Mammon sobbed pathetically. “B-Big brother, please…”

For now, that was…satisfactory. Curling his fingers around Mammon’s jaw, tilting his head back so he had a perfect view of his face, Lucifer reached down to tug the cord free from his throbbing penis, whispering the release word as it slipped away. He slammed his hips forward hard, burying the entirety of his length into Mammon. Mammon’s mouth stretched open in a silent scream. His tongue hung out lewdly. His eyes rolled back into his head. A tremor visibly rippled through his muscles. His hips strained up off the bed as his back arched to a beautiful curve. Thick, bright white ropes of semen burst out of his cock, splattering all over his belly and chest, leaving a beautiful contrast on his tanned skin. A couple of ropes even managed to reach his throat and chin. The pressure of his hole squeezing Lucifer’s cock, combined with the gorgeous sight of watching Mammon finally submit to him was enough to spring an orgasm on him. Dropping down to capture Mammon’s mouth in a rough, sloppy kiss, Lucifer moaned happily, rolling and bucking his hips to stir Mammon up deep inside.

He had gotten what he wanted out of Mammon but now was not the time to stop. Now was the time to burn the pleasure of being pinned underneath him into Mammon’s mind. Not to mention, he needed to punish Mammon for taking so long to submit to him. When he said sit, he expected his adorable little brother to do it right away. Straightening up, dragging his tongue over his bottom lip to gather up the traces of Mammon’s sweet taste, Lucifer smiled lazily. Clearly, there was still a lot of training that needed to be done. Hopefully, his cute little brother would finally wisen up and show the gratitude that he was such a patient, thorough teacher.
