Part 3: Terms and Conditions May Apply He woke up with a full bladder. Nathan stirred and sat up, rubbing his eyes. It was move-in day. He turned to his digital alarm clock. His vision hazy, it took him a moment or two to work out the numbers 9:15 in neon red numbers, staring back at him. He was lucky it was a saturday, meaning he didn't have any work dragging him out of bed. He debated rolling over and going back to sleep. Marcus and Horatio mentioned the evening before that they went out to coffee on saturday mornings, if he remembered correctly. They weren’t around. And after what the last week had put him through, he felt like the world owed him a little shut-eye. He rolled back over in bed with the slightest of crinkles, trying to fall back asleep. But his cock kept throbbing, as he felt the need to pee resurgent in his mind. In the end, he got up, his five inches tenting the front of his… undergarment... and lumbered to the bathroom that came with his master bedroom to take a piss. The agreement he made with his roommates would consider this a violation, and he knew it. Twisting the doorknob to his private bathroom, he chuckled. They were out of the house. There was no way they’d ever know, after all. The bathroom of Nathan’s master bedroom was large enough to accommodate an oversized bathtub with a jacuzzi option, as well as a nearby shower. The previous owner had incorporated a seashell design on the wallpaper, which he’d never minded enough to change. Standing in front of the toilet, Nathan began to strip out of what he’d ended up wearing when he went to bed: A large yellow onesie with a zipper down the front of the design, and ruffles along the either side of his waist, outlining where the diaper would be. Marcus hadn’t let him wear the other outfit to bed, and had also been adamant about not letting him wear his regular pajamas. With the onesie falling to his ankles, Nathan began tugging his diaper down to his knees, before sitting on the porcelain throne to pee. Nathan let out a light sigh as he let out his fluids, closing his eyes and slumping back against the backside of the toilet. Deep down, he was well aware that he would eventually need to actually use one of the diapers Marcus and Horatio were insisting he stay in. He just wanted to avoid it for as long as possible. The very idea made his face get hot. Holding his bladder as long as he could, until he lost all control and started soaking it, flooding his diaper like a helpless toddler… For some reason, he found his cock stiffening. Which made him more panicked than he would ever admit. Deep down, he worried that Marcus was right. That he actually was enjoying this on some level. And if that were the case, what did it mean? This thoughtful reverie was disturbed by the sudden pounding of a fist against the door of his bathroom. Nathan jumped, which had unforseen consequences. His stiffening cock popped up, a stream of yellow splashing against the innards of the diaper at his knees. A stain of a similar color began to form on the front of it. A voice, muffled from outside the bathroom door, echoed in. “Natie? Are you in there, being naughty?” It was Marcus. Nathan bit his lip as he pushed his dick back down towards the toilet, to finish what he started. His mind was flooding with panic. He remembered Horatio mentioning they went out for coffee every saturday morning! He hadn’t heard anyone else moving around in the house, either! How could Marcus be here? He almost responded, before biting his lip and shutting up. He didn’t know what to say or do. “Natie, I can hear you hyperveeeeeentilaaaaating!” Marcus’ voice was flush with singsongy amusement as he knocked on the door again. “If you’re on the potty, you know what that means!” “W-why are you home?” Nathan said, his voice tense. “I thought you’d b-be out.” There was a slow, deliberate chuckle from outside the door. “And you got your hands caught in the cookie jar because you thought no one was around to see you being bad, huh?” “That’s-that’s not the point!” Nathan stammered out. “You’re right.” Marcus voice dropped the moment of amusement from it. “The point is this: Are you or are you not using the potty in there, in direct violation of our residence agreement?” Silence draped over the conversation as Nathan considered his options. “N-no?” He said, testing the waters. “I’m just shaving. You were the one who said you wanted me to shave more, right?” The doorknob began to twist. “Oh? So if I come in, I won’t find a toilet yellowed with pee, and I won’t hear it flushing to hide the evidence?” Nathan jumped to his feet. “N-no! I mean, don’t come in! I’m not d-decent!” “Oh, like that’s even going to matter after a few weeks of this.” The door opened, as Marcus, wearing a red polo shirt and a pair of khaki pants, walked inside. Nathan watched his eyes whipping up and down, staring at his exposed cock, the sagging, moist diaper, and the evidence in the toilet. Nathan watched as his smile grew from ear to ear. “Naughty naughty, little sissy.” He chuckled, stepping inside and closing the door behind him. Marcus held his arms up on either side, Tsk-ing with his tongue as he continued to look, at least to Nathan, as infuriatingly smug as possible. “I’m glad I stayed behind to work on some commissions. Clearly, our little sissy can’t be trusted to keep her diapers on.” Folding his arms against his chest, Nathan looked away, scowling. “I… I was just…” Marcus snapped his fingers. “No excuses now, princess.” He turned to open the door again. “You misbehaved, and as per the terms of the agreement YOU SIGNED, that means either I or Horatio gotta punish you. Come on.” He curled his pointer finger in Nathan’s direction, leading him out of the bathroom, out of Nahan’s bedroom, and down the hall. He turned to the right, into one of the two rooms he and Horatio had rented. “Inside.” he said, curling his finger to beckon Nathan inside. They’d only been moved in for a day, but already Nathan couldn’t recognise the room after what they’d done to it. A corkboard had been mounted to the eastern wall, with various swatches of fabric fastened to it. Two metal racks had been put up alongside it, filled with odd and exotic clothing. A fuzzy tiger costume rested limply on one hanger, and a suit coat and pants draped down another. Along the opposite wall were a few pictures of men and women in various outfits. As Nathan stared at them, his eyes went wide. There was an obvious pattern. All the people in the pictures were adults wearing decidedly infantile attire: In one picture, a grinning man lay on an oversized changing table, wearing a pink onsie with white elephants patterning the fabric. On another, a woman was suckling from an oversized baby bottle filled with a white fluid, while seated in a pair of short blue shorts, held up by rainbow suspenders. The fabric of the suspenders was the only thing covering her bare bosom, and Nathan could see white bits of diaper poking up out of her outfit. And there were still more. The whole wall was a shrine to men and women in age-inappropriate garb. He blinked. “What the heck is this?” Marcus turned to sit down in a rocking chair. To his right was a sewing machine. “You like? That whole wall is devoted to displaying some of my favorite past projects. I made them myself, you see.” “You’re… a seamstress?” Nathan turned to look at him, as Marcus rocked back and forth in the chair, slowly. The question made Marcus scowl. “TAILOR. Or Seamster, if you’re going to use the masculine version of the term.” The scowl only remained for a moment before falling away, a smug smirk slithering onto his face like a snake. “But yes, that is true. That’s my job, after all. I make clothing of all sorts and sell it online. I make all sorts of stuff, custom made and fit for people’s specifications, and sell it on sites like Itsy and YeBay. But I’ve always been most popular with people in the-” his gaze trailed down towards the puffy outline of Nathan’s diaper around his waist. “-COMMUNITY, if I’m going to be delicate about what we’re discussing.” Nathan folded his arms against the soft fabric of his onesie. “Do you really do enough business with this to make a living off of it?” “I get by.” Marcus chuckled. “Horatio has a good job, and I have a background of some money, which takes a lot of pressure off. This is more of a hobby than a real occupation, true, but I’m still a professional about it.” He held his right arm up for Nathan. “But the clothing wasn’t quite what I meant when I called them ’my favorite projects’, Natie.” The words sent a tingle up Nathan’s spine. “...you mean?!?” Marcus nodded. “You’re starting to get it. Now come here and lay on my lap. Tummy down, girl. You still have a punishment coming to you.” “Nnngh.” Nathan winced, shifting his hips with a faint crinkle. He scowled and looked away. Marcus’ voice was tense. “Natie… need I remind you that you signed the agreement, fully aware of what it had in it. I haven’t tricked you at all. Rather, YOU tried to trick me.” He leaned forward, holding his hand out again. “Horatio and I have acted purely in good faith. Do you really want to get a court involved just because you welched on a deal? Come on, sit down.” With a pronounced sigh and a slight curling of his lower lip, Nathan waddled forward, laying down on the rocking chair, his back facing up toward Marcus’ head. “That’s a good sissy.” Marcus’ voice dropped lower. Nathan could feel fingers reaching down under him to unzip the onsie’s zipper. A cool breeze hit the bare skin of Nathan’s back as he felt the fabric of the onesie sliding down his body. A finger slid between his diaper and his backside. Then another. “Still dry and powdered back here at least. Of course, I’d be more impressed with your self-control if I hadn’t caught you being naughty on the potty before.” Nathan said nothing in reply, closing his eyes as he felt the diaper being pulled down to his knees. “See, Nathan, a large part of this is feeling out exactly how far you’ll let me go.” Marcus purred in the other man’s ear, his breath hitting Nathan’s skin. “Oh, you’ve fussed and fought, but you COULD have said no.” And then it happened. A firm SMACK rang in Nathan’s ears, and a rush of pain surged up his spine as Marcus’ hand hit his bare ass. “That’s one. As in ‘one more bit of proof you’re enjoying this’, Natie.” Nathan winced, biting his lip as he felt his bottom sting. To his own shame, his cock was getting stiff, rubbing up against Marcus’ left thigh. As the second SMACK hit his rump, he felt the erection twitch. “Nnngh!” His teeth pressed into his lip. His body tensed up. Pain from the spank intermingled with a pleasure he hadn’t expected, both entwined together like rope. “Mmm… my lap’s getting moist. Is the little sissy peeing?” Marcus chuckled as Nathan felt a few fingers probing his erection. “No, that’s not pee. That’s sissy juice.” He chuckled. “You’re like a leaky faucet down there, huh?” There was another powerful SMACK, and then a fourth. At the fifth spank, Nathan couldn’t hold it in anymore. He howled, clenching his fists and groaning. With every smack his bare cock was rubbing up against the fabric of Marcus’ pants, and it wasn’t making it any easier to deal with the pleasure he was awash in. He expected another spank. It didn’t come. Instead, Marcus’ voice filled his ears. “See, this is all how I can tell you’re enjoying this. You can protest, complain, and argue against it all you want, but your body is honest, even if your mouth is not.” A few fingers caressed the head of Nathan’s cock, getting precum smeared all around it. A moan escaped the man’s lips. Marcus continued to rub the other man’s cockhead, chuckling. “The tale your body is telling me is that this is a guilty pleasure for you. You like wearing a diaper. You lie dressing up like a little baby girl. You like someone giving you rules, like a parent. And when you’re naughty and break those rules…” Another solid spank hit Nathan’s bum. He moaned, loud and low. “You like having someone bigger and stronger than you punish you for being naughty. Isn’t that right?” Nathan squirmed in Marcus’ lap, his reddened, sore bottom wiggling like a lure. But he said nothing. “It’s ok. I know it can be hard to admit it.” Marcus’ voice was obnoxiously smug to Nathan’s ears. “But as I said… what your mouth can conceal, your body displays all too clearly. I wonder, if I give you a good firm spanking right here, can I make you cum? Just from that?” Before Nathan could tell him to stop, Marcus began. Where before, there had been some time between each slap of his palm, now there was only a merciless assault. Each strike was firm, fast, and powerful. With every spank, Nathan’s cock ground against Marcus’ thigh. He couldn’t stop it from happening. And with every slap, he felt himself getting closer and closer to a precipice. A cliff he couldn’t back away from, but couldn’t quite manage to leap off of. The knotty rope of pain and pleasure bound him to that spot, as he cried and moaned out, wanting it to stop, but also wanting it to never end. Tears were in his eyes. He lost track of how many spanks his da-Marcus had given him. He couldn’t think clearly enough to keep track. And then, it stopped. Nathan’s body went limp, as he panted, huffing in exertion. “Aww… looks like I couldn’t quite get you to make stickies just like that. Too bad.” Marcus said, a childish tone of disappointment in his words. “I was kinda hoping...it’d be that easy.” he chuckled. “But it looks like we’ll have to do it another way. Get up, Natie.” Nathan pushed himself up off Marcus’ lap. As he rose, the other man’s hands reached over and grabbed the diaper, pulling it up over Nathan’s groin. “H-hey, wait-” Nathan stuttered, as Marcus pulled him back down, his diapered, sore bottom sitting on Nathan’s lap. An arm snaked around Nathan’s waist. He felt Marcus’ fingers rubbing against the bulge in his diaper. “You know, the fact that it’s a guilty pleasure is why I can get away with all this.” Marcus whispered to him, grinding his fingers firmly against the dry undergarment. “You say no, but you go along with everything I demand. If you’d ever protested, even once… I’d back off. But you didn’t.” The rubbing fingers pressed in deeper. “Now make stickies, sissy baby.” Nathan couldn’t hold out for very long. Something inside him snapped, as he felt himself falling off the cliff. “Nnnnnnggggaaaaaah!” he threw his head back and cried out, as he felt himself flooding his diaper with warm, wet spunk. After a moment of intense pleasure, he slumped over against Marcus’s chest, panting. His body was sweating. He hadn’t cum that hard in a while. Marcus chuckled. “There we go. Such a good sissy, making stickies in her diapey like a little girl should. I’m proud of you, Natie.” “Y-you are?” Natie blushed. He felt different. Where there had been shame and resentment before, now he just felt warm and happy and soggy. He blushed. “Of course I am. Daddy Marcus is proud that you’ve taken your first step towards understanding that you’re a good baby.” He smiled. “After all, that’s my little project here…” He reached around and patted at Nathan’s soggy crotch. “Now we’re going to leave Natie here in her damp diapees for a few hours, at least until Horatio gets home.” He stood Nathan up and grinned at him. “Just so you can learn to enjoy it. And once my erstwhile lover returns? Well, then it’s playtime for you both.”
