Luigi couldn't remember how it all started, and if he had to guess, he'd be hard pressed to recall. He, however, wouldn't change his newfound relationship (if he could call it that) for the world. Though, in hindsight, he supposed that maybe he should try and bring up a change in their schedule. Since the meetings between the two of them was random at best given Peach's penchant for being kidnapped.
Especially since Bowser didn't seem to gain anything from their exchange monarch to monarch. If that was the actual case, Luigi pondered, then why keep up the charade? He definitely should ask Bowser afterward and speaking of the Koopa King, Luigi shifted grunting a bit. He should probably get his head back into it before Bowser noticed his game was off.
Honestly, Luigi was surprised his mind let him wander this far into actual thought while he was being railed so thoroughly. A moment later, a large scaled hand carded through his hair, scraping his scalp tantalizingly. Shivers ran down his spine as his head was lifted off the stone floor. The grip was just enough to add to his ecstacy when Bowser cantered his hips through his next thrust. Pulling Luigi upright and into his chest, Bowser lowered his muzzle and growled into his ear.
"Am I boring you?" His tone was borderline hostile.
Swallowing thickly, Luigi stuttered out his instant reply, "N-no, no, of course not."
"Hn." Bowser grunted, pushing the human back onto the floor as he rutted harder into his tight backside. "Given your distraction," Bowser mused, grounding down, causing Luigi to hiss as his knees took more of Bowser's hulking weight. "I'd say you're awfully distracted. Must not be fucking you hard enough for you to still have coherent thoughts."
That being said, Bowser reached around fisting Luigi's rock hard cock in his bruising grip and jerked him roughly. A few motions of Luigi's ignored and weeping dick had him whining with need. Bowser tugged a few more times before feeling Luigi's spend coat his fingers. Releasing Luigi's wilting member Bowser smeared his cum up his chest and pushed his fingers into Luigi's panting mouth.
Luigi wasted no time in sucking off his own cum from Bowser's invading digits as Bowser started fucking Luigi from both ends in earnest. Luigi felt his body being scrunched and constricted, making Luigi keen louder. Now Bowser had angled himself perfectly to thrust directly and continuously into his prostate. The building pressure nearly became too much for Luigi to handle. Between one aggressive snap of the Kings hips into another had Luigi screaming his orgasm into the floor.
His body clenched down onto Bowser's massive phallus, breaking his stride and igniting his flame pipe. The rumble of fire exploded out of Bowser's mouth in a castle quaking roar that no doubt was heard throughout his entire Kingdom. Thankfully, Bowser had the wherewithal to throw his head back and burn the already blackened ceiling instead of his partner. Bowser's hips stuttered a few more times before he collapsed on top of the exhausted human below him.
The two of them panted in the silent throne room, Luigi tried to wait patiently as Bowser regained his bearings enough to roll off the human. Unfortunately, as of late, Bowser's knot had been expanding when they fuck causing for the awkward aforementioned pillow talk. After today's fight, Bowser wasted little time tearing through Luigi's clothes and fucking him where anyone could walk in. Thankfully, Mario had disabled most of Bowser's army prior to making it to the throne room. So there was less likely a chance for them to be caught, but that didn't make Luigi feel better about being in the open.
Bowser scooped Luigi into his arm, holding him to his chest before waddling them down the halls of his castle. If anyone had seen them, they might have been curious as to why Luigi was naked, but no one stopped them. Luigi grimaced at the rocking motion of still having the equivalent of a human arm up his ass as Bowser made it to his personal chambers. Usually, but not always, they'd end here before they overindulged themselves in their carnal affair. Bowser wasn't much for snugging or aftercare, but at least they were now in a more secluded area.
Bowser shifted with Luigi in his arm again, now causing Luigi to essentially sit on his forearm. A sound caught between a whine and a moan squeezed out of Luigi's abused throat. His body clenched down on Bowser's slowly deflating girth, but not before he grunted a half moan himself. If Luigi wasn't careful, Bowser would end up fucking him again and not that he would mind but Luigi had a very small window of Mario free time after every rescue.
Bowser unceremoniously dropped Luigi onto his western styled bed, placing his hand onto his back and adjusting his hips. Luigi struggled on the soft surface, but Bowser just pushed him further into his bed. Tentatively, thrusting his hips before pulling out of Luigi fully. Luigi breathed a sigh of relief, willing himself to stand up and start getting redressed. What he didn't expect was Bowser grabbing him by the torso and placing him fully onto the bed. Getting his knees under himself, Luigi ended up on his elbows with his ass in the air.
Throwing a look over his shoulder, Luigi eyed Bowser speculatively as his brain and body were equal parts lethargic. The sharp grin that was met on the Koopa's face was hungry. He wasted little time raking his long tongue over the wide expanse of Luigi's back. Dragging his mouth down and began to prod his quivering ass. Luigi found himself hard pressed to complain, even if they needed to hurry; especially when Bowser licked his still oozing rectum. The gasp that came out of Luigi was a mix of incredulously and embarrassed moan. Bowser licked lower, including Luigi's quickly hardening dick before pushing his tongue back into his receptive humans loosened asshole. The moan that tore through Luigi's throat was raw and wanting, leaving Bowser to chuckle as he began cleaning out the man.
"B-Bow..Bowser." Luigi gasped in a moan. "We, I can't."
Bowser's hum of a response didn't give Luigi another chance before he flipped him over and engulfed Luigi's straining dick into his cavernous mouth. Luigi covered his face in his hands, his back arching off the bed as his overly sensitive manhood was sucked down. Bowser wrapping his tongue around Luigi's quivering cock managed to jerk him off while prodding his asshole with a blunt fingertip. The suddenness of Luigi's own orgasm exhausted him beyond the use of any more functioning braincellls. As Bowser relinquished his flaccid dick Luigi was surprised when Bowser began lining up before thrusting back into him.
Luigi tore his arm away from his face as he cried out, back arching as Bowser began to pound anew. Luigi felt overly sensitive as Bowser pounded his flesh, bruising his insides and melting his resolve. Maybe Mario wouldn't notice his absence after all.
