"Yo, Rodney." The Rattata was roused from his stupor upon hearing his name called. He had been laying on the couch, idly absorbing a movie, not really taking advantage of his free day off work, the afternoon light flowing in from their fourth floor window. He turned to see his roommate, Alec, leaning in the doorway to their apartment in his usual I-don't-give-a-fuck pose. The Pikachu wore a white T-shirt and red gym shorts, and his fur was unkempt as usual. "I'm going out to the store for some food, you want anything?"

"Uh, n-no, I'm good," Rodney replied, staring awkwardly at the Pikachu, a pang of nervousness hitting him. Alec usually didn't bother talking to him all that much. The two mostly kept to their own rooms when they weren't out at work, and when they did interact, it was never more than small talk. They coexisted just to keep the bills paid, really. But, Rodney secretly had become obsessed with him. Something about the Pikachu was just so sexy, and led him spiralling into lewd fantasies every time he laid eyes on him. He knew it was weird and wrong, but he just couldn't help himself. Alec knew nothing about it.

"Alright, be back in an hour or so," the Pikachu said, and he turned and left the apartment, the door clicking shut behind him. Rodney listened to his disappearing footsteps, tingling with nervousness and excitement at what he was about to do. A hour should be plenty. As soon as the footsteps faded, Rodney jumped off the couch and walked tentatively towards Alec's room. Gosh, he was already getting hard just thinking about it. As soon as he entered Alec's room, he saw just what he was looking for. He had known from glances into this room that Alec left his clothes strewn about the floor, including, this time, a pair of maroon-colored underwear. The air smelled of Alec's natural musk. His lust exploding within him, Rodney made a grab for the underwear and pressed them up against his muzzle, giving a deep sniff. He let out an involuntary moan as he let Alec's musky scent envelop him. It was everything he'd hoped for. God, he'd give anything to let the Pikachu dominate him, force him to huff his sweaty balls, use him like a toy. Driven crazy with the lust, he used his other hand to pull his pants down and jack himself off, fantasizing wildly as he continued to inhale Alec's heavenly scent.

He pulled himself back for a second as he realized he shouldn't do this in Alec's room. As much as he wanted to drive himself crazy in here, Alec would probably notice any mess he made. So, he took himself to his own room and plopped down on his own bed, still huffing wildly and pumping his cock fast and hard. Again and again he drove himself to the brink of climax, before letting go and letting his member twitch and throb with need as he continued to fantasize about Alec's hot sweaty body. This underwear had spent days pressed against Alec's cock and balls, it was drenched in his smell, Rodney couldn't fucking handle it. He was such a needy little pervert, he needed Alec's cock so fucking bad, he'd do anything. Nothing else mattered except enveloping himself in the Pikachu's sweet musk.

Suddenly, Rodney heard something, he didn't know what, but it made him stop in his tracks,thrown suddenly out of his high. Were those...footsteps again? Before Rodney had time to process, the door to his room flung open and Alec was standing there.

"Hey, have you seen my ke-oh, shit." Alec said as he looked over Rodney. The Ratatta had frozen in place, in a state of shock at being caught in the act. "Is that my underwear?"Alec said casually, pointing at the pair of briefs laying on Rodney's snout. He sounded more amused than anything, wearing a smug sort of grin. Rodney just sat there guiltily. All the pleasure from before had faded, and now he felt like just a weird creep who had been fantasizing about a roommate that he barely knew. He took the underwear off his face,shaking, trying to think of anything he could say as an apology. "I-I..."

"Dude, it's okay. If you wanted to fuck so bad you could have just asked me," Alec said. "No need to go full porno mode with my underwear there."

Rodney couldn't believe what he was hearing."Wh-what?" he stammered.

"In fact," Alec continued, pulling down his shorts and underwear,"you could suck my cock right now." His pink cock was already poking out his sheath as his bottomwear dropped to his feet. Rodney just stared like an idiot, not fully comprehending what was happening, but his horniness flaring up wildly again.

"Go on, suck my cock. I'm giving you permission." Alec said commandingly as he stood there. Rodney got off the bed and crawled over to Alec's exposed member while pulling his own pants off, not even feeling entirely in control of his own body. Alec's cock throbbed in front of him, now at full mast, his yellow balls sagging below. Rodney could feel the heat radiating off the Pikachu's genitals, and the musk hit him in waves. It smelt so fucking good, those dick and balls being cooped up so long in underwear and now being let out to breathe. Rodney pressed his nose up to Alec's furry balls and drank in the sweet, sweaty scent. It was so much better than even the underwear, the real thing,right here in front of him,and free for him to worship. He looked pleadingly up at Alec, getting a full view of his erect cock, now glistening with pre, and Alec looking greedily down back at him, wearing a look that said he knew that Rodney was his to use.

"You like the smell of my sweaty cock and balls?" the Pikachu said smugly. A strand of pre dripped down onto Rodney's face, and he gave a quiet moan. He had nothing to worry about, he knew that now. Alec was going to let him indulge in all his wildest fantasies. With one last sniff of Alec's balls, Rodney moved up to take in his full length in his mouth. Immediately, the taste of pre and musk filled his throat, giving another moan of purest ecstacy, closing his eyes in the pleasure. His own cock twitched frantically beneath him, desperate for release, but he wasn't going to let it, he was going to be obedient and let Alec decide when he could cum. Besides, he wanted this to last as long as possible. He took Alec's cock in his mouth again and again, deepthroating the whole thing, one hand on the floor and the other grasping the base. Up and down he moved, lost in the motions, the two grunting and moaning in pleasure. "Oh, god fucking damn it," Alec said suddenly, and with both hands he grabbed Rodney's face and starting humping him like a fleshlight, doubling their pace. Rodney moaned uncontrollably, muffled by Alec's cock, his world engulfed in the taste and smell of Alec's musk, and horny beyond words.

Suddenly, Alec pulled out, leaving Rodney dazed and disappointed by the sudden lack of stimulus. "Nope, I have more plans for you," Alec said, smirking and letting go of Rodney's head. "Get on the bed," he said, gesturing towards it. Rodney obeyed, lying face down on the bed, ass up in anticipation. "Hmm, don't get too ahead of yourself. I wanna have a little more fun with you. First, the shirts have gotta come off." He flipped Rodney on his back so he face up, and pulled his shirt off before removing his own and discarding them haphazardly on the floor. His full odor was unleashed for Rodney to sniff, gasping heavily as he took in the natural scent of Alec's musk. Alec smirked at him for a moment, then turned around, and sat his ass directly on Rodney's face.

"MMph!" Rodney moaned, taken completely by surprise. Now he was enveloped in a different, but similiar sexy smell as it pressed against his nose. "Mmm.." he moaned further as he huffed the scent of Alec's sweaty ass, pressing down on him. This was even better than he could have fantasized. His cock twitched excitedly, nearly reaching a hands-free climax, but he willed himself to resist, even though it was starting to hurt a little.

"Oh, you like that, hm? The smell of my ass? God, you're such a needly little slut. I should have done this way sooner," Alec said as he rubbed his hole back and forth on Rodney's face. Rodney just moaned more in response as he took in the musky smell and felt Alec's balls dragging across his chin. His mind was completely scattered now. His only thoughts were of being Alec's slut.

The Pikachu continued rubbing his ass in Rodney's face, humming innocently as he did so. Rodney had to focus hard to stop himself from cumming, giving out intermittent squeaks and moans. "Alright, that's enough," Alec said after a couple of minutes, and got up off Rodney's face. Rodney gasped at the relief in pressure, and laid breathing heavily on the bed. "Time for me to fuck your hole," Alec said teasingly, and he flipped Rodney on his back again. He ran a finger thoughtfully up Rodney's hole, spreading an asscheeck with the other. "Hold on," he said,"I gotta go get some lube. He ran out the room, to his own, and Rodney was left alone with his thoughts for a bit, ass still in the air and shaky all over. He would probably be able to do this anytime he asked now. Maybe he could be Alec's full time bitch. He shivered excitedly at the thought, drinking in the air that was musty and smelled of sex and Alec's stink. He wanted to smell this forever.

"Yoohoo," Alec called from the doorway as he walked back in, carrying a bottle of lube. "Ready to get railed?" Rodney nodded slowly, looking down. "Alriight." Alec hopped onto the bed and back behind the Rattata, squirted the lube a couple times directly on his backside, and used two digits to finger his tight asshole. His hot breath hit Rodney's rear as he leaned in close and explored his depths with his fingers. Rodney whimpered at the sensation. Alec stopped and said, "You know what? Beg for my cock. I wanna hear you be the best bitch you can be." Rodney whimpered louder, before stuttering, "P-please fuck me..."

"What?" Alec demanded. "Speak louder. Couldn't hear you."

"PLEASE FUCK ME! FUCK MY ASS HARD!" Rodney screamed in response.

"Mm, that's better," Alec said smugly. "Goddamn." From the sound of his voice, he was clearly enjoying dominating Rodney in this way. He guided his cock into Rodney's asshole, and let his full length linger there. Rodney could feel it throbbing against his tight, sensitive insides and almost brought himself over the edge. But Alec seemed to read his mind, reaching for his cock and giving it a quick jolt to stop it in its tracks, causing Rodney to yelp. "Not yet, you rat bitch," Alec said. So cruel, but Rodney wanted to keep going, to be a good, obedient bottom. Alec started fucking him in earnest, starting slowly but quickly reaching a speedy pace, bent over and grabbing Rodney's waist for full leverage. With each thrust, Rodney could feel Alec's cock hit the most sensitive parts within him. The air smelled of sweat and sex, it was heavenly on his nose. Again and again, Alec slammed his length into Rodney's tight asshole, sending waves of pleasure through Rodney's body. Again and again, Alec denied him his orgasm, shocking his cock and remarking on what a little slut he was. It could have been 5 minutes, it could have been hours, he had lost track of time. Until, eventually...

"God, I'm gonna cum," Alec groaned, reaching maximum speed in his thrusts. "Get ready, you little slut." Rodney heard him groan in anticipation, and panted heavily, driven mad by the need to cum himself. At that moment, Alec reached for Rodney's cock and pumped it hard, clearly intending to finally let Rodney have his release. Rodney yelped at the sensation of Alec's hand jacking him off, delirious with the anticipation of what was about to happen"Gah!" Alec yelled as he came hard into Rodney's insides. As he felt the warm gush of Alec's load in his ass, Rodney finally reached his own peak, whimpering hard and closing his eyes tightly to focus on the pure pleasure of his release. His cum shot out of him with the power of a bullet, drenching the sheets of his bed as he shot ropes and ropes of cum out, a load that he had been aching to release for so long. It seemed to go on forever, far after Alec was already empty, his cock twitching madly and shooting smaller and smaller loads as Alec pumped it. But eventually, it stopped, and sat there dripping the remains down Alec's hand.

"Damn, that was ... incredible. You are really fucking horny, aren't you? How did I miss out on this the whole time?" He pulled his cock out and took his hand off Rodney's member, and the two panted heavily in the aftermath of their intense fucking. Rodney's brain and body were completely scrambled, and he collapsed in the pool of his own seed. He was completely spent, but so completely satisfied. He felt no guilt about what had just happened.

"Well, then, hm... I'll leave you to clean up here," Alec said, jumping off the bed and grabbing his clothes. "Next time it'll be in my room." Next time ... Rodney drifted into thoughts about doing this every day. Being his full time slut. He looked over the musky pair of underwear that had started it all. Certainly, his life was about to get a lot more interesting.
