I tried to write hypnosis a bit differently from the typical approach, but I'm not sure if it's a better or worse angle. Either way, I hope you enjoy it!


Even before he opened his eyes, Sigma realized he wasn't in his own bed. I didn't mean to spend the night here. . . the cheetah thought to himself. He opened his eyes and yawned quietly, taking the opportunity to look around. How did I even fall asleep? I swear I was wide awake just before getting ready to leave. Sigma placed his feet on the floor and stood as he continued mulling it over in his mind, attempting to recall the details leading up to his apparent slumber. I grabbed the bag with what little I brought here. . . I made my way to the door, kissed Obrum goodbye. . . Then what?

"Then what. . ." he repeated softly, nearly bumping into his boyfriend as he shambled along. "Oh!" they both exclaimed together, each of them trying to get out of the others' way. After three failed attempts, Obrum simply sighed and pulled Sigma in for a brief but warm hug. "Morning," the black gecko said, kissing his mate's forehead . Sigma smiled and let Obrum walk past him, watching as he made his way to the walk-in closet and closed the door. "Uhh, Obrum?" Sigma began, knocking gently on the door with a single knuckle. "What happened last night, exactly? I could've sworn I was about to leave, but. . ." the cheetah left his question hanging in the air for his boyfriend to answer, but he never did.

Well, we're both naked. Did we have sex. . . ? Sigma mused, putting a thumb beneath his chin. No, I would have remembered that. Unless I got drunk off my ass, maybe? But if that's the case, where's my hangover? And why isn't the apartment a mess?_Sigma shook his head and ran a paw across his head, deciding to figure all this out later, when he wasn't so groggy. _It's way too early to be thinking so much, he told himself, clearing his mind, shutting his eyes and saving himself the headache. He almost wanted to fall back asleep, but the sound of the closet opening ruined his chances of doing so.

"I've got some things for you to try on," the emerging gecko said slyly, tossing a skimpy pink dress and panties on the bed next to his boyfriend. Sigma opened an eyelid to look at them, then turned his gaze to Obrum. "Alright," the cheetah said plainly, sitting up and removing the dress from a dull gray book he hadn't noticed before. Something about hypnosis, or something, he muttered mentally as he skimmed the title, almost immediately returning his attention to the revealing piece of clothing he was holding. This would look good on me, he thought, not protesting in the slightest as he slipped it over his head.

Sigma fiddled with the straps until they were snug over his shoulders, but Obrum wasn't quite so gentlemanly to help him zip up the back. "Looks a hell of a lot better with the back exposed," he reasoned with a cocky smile, apparently satisfied with the little amount Sigma managed to zip up himself. "Panties next," the reptile told him smoothly, his voice as pleasing to the ear as it was unnecessary for him to use it. Already equipped with the undergarment, Sigma pulled the little thing up to his crotch and wasn't surprised to find it could barely hold his flaccid equipment. Sigma could see his boyfriend's shaft already beginning to swell from the sight, and the cheetah couldn't help but smile innocently. "You like this?" he asked, almost surprised.

Obrum opted not to answer, and instead gave a soft command: "Lie on your back." As if he had no free will at all, Sigma immediately complied and did as he was bid, his slender legs hanging off the mattress as his back met the sheets. "I'll be back soon," the gecko said coyly, disappearing from the bedroom. Sigma attempted to move, but every time he tried, he convinced himself he didn't actually want to.Why would I get up? He told me to lie down, so that's what I'm gonna do. It's not like I'm frozen in place or anything; I'm just comfortable.

Sigma sighed as he waited for his master. . . Master? 'Boyfriend', I meant 'boyfriend', he corrected silently, rolling his eyes at his mistake. I guess I didn't get enough sleep after all. The only thing Obrum could be master of is. . . his thoughts trailed off into the gutters, and he was extremely tempted to complete the statement with 'me and my slutty ass'. It was with that stirring thought that Obrum returned, his finger supporting a thick diaper by its leghole.

"You want me to wear that?" Sigma asked, his tone completely lacking any sign of unwillingness. "You heard it here first," Obrum replied snarkily, tossing the diaper onto his boyfriend's face, albeit unintentionally. "Don't put it on just yet. We'll save it for later," Obrum told him, closing the distance between them and joining the relaxed cheetah on the bed, kneeling over him. "Now, take that fuckin' thing off your face and blow me." Without the slightest hint of hesitation, Sigma's body responded. He threw the diaper from his visage and raised up to meet his boyfriend's cock, the taste of it all too familiar.

Obrum hissed in satisfaction, letting the warmth envelop his hardening shaft as Sigma swirled his tongue around it with practiced experience. He couldn't help but moan submissively as he swallowed inch after inch of the reptile's meat, coating it with a thin layer of drool before beginning to bob his head back and forth. Sigma felt his boyfriend place a hand on the back of his head, clutching his vertical stretch of black hair. "That's a good girl," Obrum moaned softly, idly running his free hand down Sigma's pink dress. Blushing, Sigma tightened his lips and decreased his pace a little, making sure to savor every last centimeter of cock.

Although Sigma didn't have any clear memories of ever being dressed up like this before, he couldn't shake the feeling of complete normalcy. It was as if his brain didn't even register cross-dressing as a kink, which he might've considered strange on any other day. "Ahh, fuck," Obrum sighed, pushing his length to the back of his slut's throat. "How's that taste," he asked rhetorically, letting Sigma suckle and breathe around his base for a moment. "Mmf. . . Well, enough of that for now."

The lecherous gecko pulled out and flipped his partner onto his belly, and Obrum's hands immediately took to groping what the panties didn't cover. "Raise it," he commanded, sliding his hands over the furry pair of buns with gentle ease. Sooner than Sigma could register, his ass was in the air, presenting itself almost on its own. "Looks damn good when it's up, doesn't it?" Obrum grabbed the cheeta's balls through the thin undergarment, fondling them while his other hand slipped the panties down just far enough to expose Sigma's defenseless hole. "Of course, it looks damn good in any position."

Sigma grunted as the gecko's rod poked against his entrance, the tip already wet with pre-seed. "Relax for me," Obrum said, slipping a drool-lubed finger a few inches into Sigma's backdoor. It was met with little resistance, as was the request. The cheetah's ass somehow managed to fully loosen its muscles to the best of its ability, and Sigma found he couldn't clench them no matter how hard he tried. "Ahh. . . Nice and roomy." Obrum spent ten or so seconds pumping his digit back and forth, sometimes pushing it in to the knuckle before replacing his finger with the pounding shaft between his legs.

"O-oh god," Sigma hissed, his eyelids nearly fluttering as his boyfriend's cock entered him. He wasn't sure if not being able to tense up made it feel better or worse, but he knew for certain he didn't want it to stop. Before long, Obrum bottomed out inside his partner, his balls pressed firmly against Sigma's taint. "Feels nice, doesn't it?" He asked, fiddling with the cheetah's panties as he took a moment-long break. "Being so relaxed with such a thick dick inside your girly ass."

Sigma nodded and resisted the urge to push back against his apparent master, the pounding against his walls making him ache for movement. A sudden, fleshly slap signaled the beginning of said movement, and Sigma gasped in pain and surprise as he was rammed inside of. Pre-seed spilled from the cheetah's tip and into the fabric of his strained panties while Obrum pulled his way out, his long spear setting every centimeter of his slut's passage ablaze.

"Kinda hurts, doesn't it?" the slender gecko asked, his voice dripping with lechery. "But we both know you love it." Without warning, Obrum slammed all the way inside again, a second loud slap making itself heard between their flesh. Sigma hissed, the little bit of drool his boyfriend used for lube not doing much at all. Obrum chuckled and picked up the pace, now thrusting in and out with some semblance of a steady rhythm. "Even when you're relaxed you're tight," he stated quietly, slipping a hand down Sigma's dress and groping his chest. His fingers slid through the thick fur while he pounded his cheetah from behind, the slaps only getting louder and wetter as time went on.

While Obrum's left hand was busy with the chest, his right explored the pleasantly round butt he was using, expertly kneading the flesh beneath the fuzz. "Who's got a nice ass?" Obrum growled into Sigma's ear, the submissive feline's body shuddering with excitement from his tone. "I do," he responded without a hint of reluctance, the stinging of his backdoor beginning to fade. This had always been his favorite part; when it started to feel nice not because of the pain, but because of the pure pleasure. "Damn right," he confirmed with satisfaction, increasing the force of his thrusts as a sort of reward for answering.

Moans of various volumes escaped through Sigma's lips as his boyfriend began plowing his ass to hell and back, his wrinkled dress still playing host to Obrum's wandering hand as it moved down to rub his panting belly. He received a few playful smacks on the rear from Obrum's right palm, Sigma's small panties doing little to shield his ass from the harmless abuse, but the two of them hardly wanted it any other way. Sigma was perfectly happy with his useless undergarment, which had let his balls and tip slip free and left his stuffed asshole entirely exposed with a single push downward. Obrum ceased groping and slapping the cheetah's ass and instead roughly pulled his tail, which made Sigma bite down on the sheets, unsure of whether he had just felt pain or pleasure.

"God," Obrum breathed, barely audible over the ruthless fucking going on. "You just love this, don't you?" Without even thinking, Sigma nodded as best he could, trying to press his hungry butt against the gecko's crotch. He must be getting close, the feline told himself dully, almost letting his tongue loll out while bliss overtook him. Obrum always vented his lust via dirty talk in an attempt to make himself last longer, and it didn't take Sigma long to learn that more filthy language meant a closer climax.

The increasingly heavenly sensation of being screwed made him realize that he was pretty close, too. The tip of Obrum's shaft neared Sigma's pleasure button with every thrust inside, and the gecko's left hand finally managed to reach his boyfriend's cock and jack him off. Sigma's chest was heaving from all the attention his rump and torso had gotten from those soft, curious fingers, but he feared he might never catch his breath again once those fingers wrapped around his pounding, neglected meat. The panties had been slipped away even more, reduced to a soaked piece of fabric that barely covered half a ball as Obrum stroked Sigma's length, bringing him to new levels of ecstasy.

"You soak my hand, and I flood this fucking ass of yours," the gecko growled, recklessly slamming into Sigma with erratic timing. It was apparent that neither of them could be more turned on if they tried, which didn't help in attempting to hold back their orgasms. "Deal," Obrum asked, his question sounding much more like a statement. Sigma nodded again, using the last of his will power to resist his climax for a single second more before it came splashing out against his wishes.

Seed gushed and flew into Obrum's palm and onto his digits, the warm liquid slipping up and down Sigma's cock as his boyfriend continued jacking him off., making for a much improved handjob. The hypersensitivity made him shudder, but not as much as the sudden influx of cum pouring into his depths. "Tense up!" Obrum barked. Before he even registered what Obrum said, Sigma clenched his plugged pucker and felt a world of difference. He could feel every small detail of Obrum's cock with his tightened tunnel, and the added pleasure of feeling more stuffed forced a few extra ropes of seed from him, and apparently from Obrum as well.

Their intense orgasms eventually settled down, leaving them both panting and exhausted. . . And wet. Very wet. "How was that?" Despite the roughness of what just happened, Obrum's tone was actually rather soothing and sweet. It made Sigma feel at peace, at least for the time being. "It was great," the cheetah replied breathlessly, his boyfriend still gripping his spent cock firmly. "Damn right."

Sigma inhaled sharply when Obrum pulled out without a care, his lengthy rod flopping free of the constricting hole and splattering globs of cum this way and that. He gave Sigma's raised butt an admiring pet and proceeded to flip his obedient slut over, forcing him belly-up. "Your panties are soaked," the gecko observed, allowing his eyes a split-second glance at the useless underwear. By this point, all of Sigma's goods were completely exposed, having worked their way out of the fabric and drenching them in the process. "Let's replace it with something that's a bit better at covering things up," he stated, giving Sigma's tummy a brief rub-down underneath his dress.

He stirred contently before setting eyes on the diaper from earlier, having been dragged into view by Obrum's other hand. "Oh, I almost forgot about that," Sigma mused, tentatively taking the diaper from his boyfriend and putting it beneath his pelvis. He wrapped it around his crotch and pinned it closed, each half of his body now making quite different statements. "Fembaby," Obrum chuckled, leaning over his willing slave and planting a kiss on his lips. Although surprised, Sigma instinctively returned the kiss and raised his arms to wrap around his lover, but the connection between them was broken before it had the chance to turn into a make-out session. "You butt. . ." Sigma muttered, disappointed the moment didn't heat up to his expectations.

The gecko smirked as he pressed a palm against Sigma's cheek gently, caressing it as he spoke. "You're a baby. What do babies do in their diapers?" Obrum questioned, his eyes glinting with lust. Before Sigma could chance a guess, Obrum interrupted him with his soft but commanding tone. "Piss yourself," he ordered, taking apparent joy in watching the immediate reaction. It felt awkward, but Sigma could do nothing but gasp and relax as pee suddenly poured against the soft material, the warmth and moisture pressing against his flaccid, sticky member. No visible stains could be seen on the outside, but in less than three seconds, it felt as if there was a flood inside his diaper.

"Nice and warm, isn't it?" Obrum chuckled, setting his fingers directly on where the wet spot should have been. Sigma didn't really acknowledge the question; he simply continued relaxing his muscles and let the oddly soothing sensation flow over him. Is this even normal? Sigma's mind asked, almost feeling a twinge of surprise at what was happening. This can't be normal, can it? Was everything else we did today also strange for us? Twelve seconds had passed since he began wetting himself, and he could feel it was about to slow down.Do I even care about any of that? Knowing there's something weird about all this would just make it even hotter. . . The added humiliation, or the. . . the, uh. . . What was I even thinking about? This feels so nice. . . It's kind of making me hard.

Despite the enjoyment of his own golden stream coating his penis and crotch, it steadily came to an underwhelming end "What was that, half a minute? Not bad," Obrum said, pressing his palm against the used diaper. "Can't feel a thing." The gecko grinned and rubbed his hand against Sigma's groin, leaning in for another kiss. But I can, the feline practically moaned to himself, his eyes half-lidded with desire and his cock fully erect from the self-shower. Their tongues entwined and tasted the other, while their lips smacked and clashed whenever they could. With deft skill, Obrum undid Sigma's diaper without looking and took to stroking his doubly-soaked meat again, not minding the lewd texture or musky scent in the slightest.

Obrum's other hand slipped underneath the cheetah's rear and began groping once more, kneading the sore buns with welcome intensity. Reduced to a writhing mess, Sigma moaned and gasped into his boyfriend's maw, having already traded an impressive amount of slobber with him. Sigma's arms wrapped around Obrum's body as they had meant to earlier, and he honestly couldn't guess how long their wet lips and tongues wrestled before Obrum's handjob paid off. Seed splattered onto his matted fur, which carried an abundance of scents already, but the reptile didn't stop there.

"Clean them," he commanded smoothly, holding up two fingers in front of Sigma's flushed face, both of which were coated in his own essence. Still breathless from his second climax, Sigma brought his head forward and lapped up the creamy liquid with his tired tongue, the taste not altogether terrible. With some reluctance he swallowed, and was rewarded with another spontaneous, passionate kiss. Sigma instantly melted into it, gladly allowing his lover's tongue to get a taste of his own via a few lengthy licks. "That's my fuckin' girl," he praised, squeezing Sigma's ass powerfully after they disconnected.

"Come on, sit on my lap," Obrum told him, sitting down on his butt and waiting for Sigma to get into position. The cheetah's bottom soon met Obrum's legs, but he didn't appear to be satisfied just yet. "I meant," he whispered into Sigma's ear, clutching the feline's chest through his dress. "Put my dick between those spotted cheeks." Nodding almost apologetically, Sigma repositioned his butt until it met Obrum's specifications. "I almost want to fuck that starving ass of yours again, but. . . instead of plowing the hell out of it, I'll give your pucker a break and just rub my dick against it. How's that sound?" Without waiting for a response, he made due on his promise and began grinding between Sigma's rear end, turning any reply he might've had into surprised moans.

"This is what your ass was made for," Obrum whispered into his ear, kneading those desirable buns as he spoke. "To serve my cock." As if on cue, Obrum's length twitched against Sigma's taint and splattered it with pre-seed, soaking it even more. "Say it. Admit your ass was made only to please my big, chubby dick. Tell me how much of a complete buttslut you are, and how your worthless asshole suddenly has purpose whenever I decide to use it."

Gasping, Sigma began to repeat everything Obrum had told him to. He confessed he was a buttslut, that his ass only existed for his boyfriend's cock, and it wasn't long before Obrum had him saying even more demeaning things. Or, they would have been demeaning, if Sigma had any sense of what was normal that day. "I'm a whore", "I'm your cocksleeve", even going so far as to have him say "Your dick is my god". With talk like that, it was a miracle Obrum lasted as long as he did. A few lengthy, carnal moments passed, and the gecko coated Sigma's taint with another batch of seed. With the last of his lust, Obrum ordered his partner to suck him clean, grinning the entire time Sigma had his ass-flavored shaft inside his mouth.

"Well," the reptile muttered, finally removing himself from the well-used bed. "That's enough of that." Both of them were flush, panting, and all-around tuckered out from their long session, but Obrum had one more thing to do. He knew it would have taken at least a few more months to get Sigma comfortable with such kink-heavy sex, and he didn't want the poor cheetah to be brainwashed forever. "It was fun. Maybe we'll do this again sometime soon, and on your terms."

The sound of a loud snap was the last thing Sigma remembered before waking up in his bed, the memories of last night's visit to his boyfriend's still fresh in his mind. He's such a sweet guy, Sigma thought dreamily, completely infatuated with that lovable butt. It was only after he spent a few moments thinking about him that he realized he'd apparently overslept by three hours, and he quickly dashed out of bed to get ready for a party happening in town. Obrum would be there, and he couldn't wait to spend another fun night watching movies and playing games with him.
