The gap between medicine and weaponry is where poisons dwell. Gero knew that producing an heir was something he had a duty to perform, or else Akari would perform it instead. After another one of their nightly sex sessions, Kinosaki had taken Gero aside and told him to create something that wasn’t a poison. The first thing Kinosaki wanted him to make, that he promised to be a guinea pig for, was a pill that could significantly increase the amount of semen a man could produce. The excuse was that it would ensure that whoever he married, he would produce an heir on their honeymoon night. Kinosaki tried out the various doses, enduring the unpleasant and sometimes nauseating side effects.
The most effective one made his balls swell until they were sticking out the sides of his panties, with the cockhead and some of the shaft poking through the waistline. The tip of Kinosaki’s cock rubbed against the underside of his dress, leaking precum and creating a white spot where the tip of his dick tented it. He was so aroused that the slightest stimulation made his cock grow. It could become soft again with a few minutes of waiting, but Kinosaki lifted his skirt and showed it growing to Gero, wanting him to see the change from small and soft to long and stiff. His balls had gotten plumped, filled with so much cum that it took several ejaculations, each as thick as the last, to get it all out.
Kinosaki showed off how effective the medicine had become by resting his glans, freshly peeled from his foreskin, and rested it on the edge of a sake cup. A few vigorous strokes of his cock, and a fountain of cum gushed out the end of his tip. It clung to the bottom of the cup, filling it up to the brim. Kinosaki was blushing, looking like he was about to pass out after shooting that much in one go. Gero took it to his lips, swallowing a sip of Kinosaki’s cum. He knew where it had come from, and it wasn’t poisoned. After getting a taste, he drank the rest of it in several loud gulps, before going in for a kiss. The kiss made Kinosaki hard. WIth the smell of cum on his breath, Gero lowered himself onto Kinosaki’s soft, dripping cock, sucking it until it was hard again inside his mouth.
The two of them took a dose of the new medicine at the same time. The pill got them extremely horny. Their cockheads touched against each other, and they weren’t even able to make it back to Gero’s bedroom before they were having wild, animalistic sex. Gero’s pill had a higher dose, as he was more resistant to poisons than Kinosaki, who relied mostly on charisma. Gero plunged his cock into KInosaki’s tight and waiting anus, thrusting over and over with repeated wet sounds, lubed up by his own leaking precum, that quickly turned into a slimy film of white inside his partner’s asshole. He had only exhausted his supply of semen after ejaculating six times in a row, with his load remaining thick and gooey each time.
“Geez, my ass is sore,” Kinosaki said. “I came while you were fucking me, but I think it’s time for a little payback.”
Gero was laying on the floor, drinking from a freshly mixed sports drink to help rehydrate himself after exhausting so much cum. Kinosaki, his leaking cock bouncing, put his hands on Gero’s legs and spread them apart, rubbing his cum-smeared dick against his asshole. Gero’s cock sprung back to life for one more round, hard enough to fire a final, though weaker, blast of cum onto Kinosaki’s stomach. As Kinosaki thrust tightly into Gero’s butt, the cum that had been deposited in his own ass was being pushed back out in the form of small, but wet cum farts. The dribbling cum, as thick as pudding, ran down Kinosaki’s thighs and splattered over his butt cheeks.
“You filled me with so much that my belly’s looking a little bloated,” Kinosaki said. “I take a lot of care in maintaining my figure.”
“I didn’t know the medicine would be that potent,” said Gero.
“You’d better take responsibility if anything happens,” said Kinosaki, thinking he was joking around.
A few weeks later, Kinosaki was informing Gero about the next potential partner he had arranged to meet. Though Kinosaki was dressed as a girl, he and Gero entered the men’s bathroom. They stood in front of the urinals and pulled out their soft and floppy cocks, holding them up to the white walls in front of them. Kinosaki took out something that he had gotten at a nearby convenience store. Gero recognized it as a pregnancy test.
“Why do you need one of those?” he asked.
“I’ve been feeling nauseous lately,” Kinosaki said. “There’s this strange feeling in my balls. The only thing I can think of is that you filled my ass recently, so I wanted to give it a try.”
The pregnancy test, ripped from its packaging, was held in front of Kinosaki’s dick. Gero turned his head to the side, catching another peek at Kinosaki’s flaccid cock. The pink head was hidden in his foreskin until Kinosaki tugged back, getting his cock slightly harder and aiming for the pregnancy test. The test was soaked in his warm piss. Kinosaki set it on top of the urinal and kept peeing. Gero stopped and zipped up his pants, washing his hands while Kinosaki was still going. Kinosaki took the test and washed his hands as well, looking at the lines. This was something he had done as a joke, of course it was going to say negative.
Kinosaki looked up in the bathroom mirror. His eyes were widened in shock. He held the test between his fingers and shoved it in Gero’s face. The test was so close that Gero could smell the scent of piss. “It’s positive. You got me pregnant!” Kinosaki said. Those feelings of shock quickly turned into pride. He had honed his craft as a marriage swindler by playing up his natural boyish cuteness. “It must be because I’m so cute. Now you don’t have to worry about an heir.”
“There are bigger problems right now,” Gero said. “I won’t believe it until I see proof.”
Eight months later, the changes in Kinosaki’s body were undeniable. Though he was still wearing dresses and other girly clothes when out with Gero, there was a noticeable bump in his stomach. What had once been flat and toned was now round and taut, sticking out from his body. It was warm to the touch, with a baby inside. A few weeks before reaching the eighth month, Kinosaki’s belly had grown so large that his navel inverted, and the dark line that had been slowly growing became more pronounced. After another matchmaking attempt for Gero, the two of them returned home. Kinosaki had been texting Gero that he was uncontrollably horny, and wanted a dicking to calm his nerves.
Upon making it back to the apartment, Kinosaki took off his dress. The outfit fell to the floor, revealing that Kinosaki’s soft butt, already one of his most feminine parts, had grown softer and wider. In place of the cute panties he used to wear, a far more comfortable pair of maternity underwear had been ordered. The stretchy material accommodate his belly, fitting well and showing both of his bulges. The constant hormones of his unusual pregnancy had left his cock getting erect at inappropriate times. The shape of his erection was visible inside those panties, his balls full of sperm and his long shaft, longer than Gero’s, pulsing with anticipation.
The biggest change in the past few months, besides the belly, had been happening above. Kinosaki had always padded his bra when crossdressing, making it appear that he had a fairly ample bust. Over the course of the past few months, his chest had grown to match the size of the pads he once used. Kinosaki sported a natural pair of H-cups that were full of milk, with nipples darkened from a boyish pink to a more mature shade of brown. His cockhead had undergone a similar change in coloration, and his balls were producing more cum than usual.
Kinosaki sat on the couch. His naked, pregnant body was making Gero feel a certain way. He sported an erection in his pants. He had months to process what was going on, but knowing that Kinosaki was bearing a child the two of them had made together, somehow, was enough to make him happy. He would rather see Kinosaki pregnant than Akari. Kinosaki held his erect cock in his hands, shaking it and spraying drops of precum onto his belly and thighs. The contrast of his big, meaty cock compared to his pregnant belly made him look more alluring. Kinosaki stroked his belly, going down to the blonde pubes hiding underneath.
“Come on, papa,” Kinosaki said. “Fuck me like that night you got me pregnant.”
“I’ll show you that I can be a good father,” Gero said. “I hope they take more after your side of the family.”
“Me too,” Kinosaki said, blushing.
Gero got on his knees in front of the couch. He stroked Kinosaki’s belly. Every few strokes, he felt the baby kicking inside. Kinosaki had been going to ultrasounds, and some sort of womb had formed inside his ass to allow the baby to develop, while still allowing that hole to perform its normal functions. Neither of them worried about the small details. What was important was that Kinosaki had a safe birth. Gero’s hand moved further upward, grabbing onto Kinosaki’s soft breasts. His fingers danced across the mound of fat that had grown on his chest, bigger and softer than any pad. They were slightly saggy from gravity and holding so much milk, but would perk up once they were emptied.
He licked Kinosaki’s nipple, gathering up the drops of sweet white milk that had been leaking out. The milk had a mild flavor. When a lot of it was pooled on his tongue, it reminded him of the mixture used in his favorite candy packets. A faintly spiced fruit-like taste that played well with his selective palate. Perhaps Kinosaki’s breasts were producing something to his liking. He sucked Kinosaki’s boob, drawing out lines of milk. The warm milk coated his throat, each lick and swirl of his tongue against Kinosaki’s dark nipples making the swindler’s cock twitch.
“I can’t believe you have real boobs now,” Gero said.
“The doctor said I might lose most of them after I give birth, but it’s all speculation. Cases like mine are extremely rare, and I can’t exactly let them know about the criminal underworld,” said Kinosaki. “I’m enjoying them while I have them. They’re so soft, and the way they bounce... and are full of milk.”
While Gero had been sucking on Kinosaki’s boob, a line of milk ran down his other breast towards his swollen belly. Gero rubbed the breast milk into Kinosaki’s stomach, using it as lube. The more he played with Kinosaki, the harder his own erection became. Moving by instinct, his hand grabbed Kinosaki’s dick, gripping the thick shaft between his fingers. A line of precum ran down the darkened tip onto his hand, coating it in a slick layer. Gero released his grip from the slick cock, letting it bounce before wrapping his lips around the cockhead. He had hesitated the first time they had sex. Now he took Kinosaki’s long cock into his mouth so deeply that it was almost in his throat, letting his saliva run down the length of his shaft.
“Good boy. I didn’t even have to ask you to suck,” Kinosaki said. “My balls are so full from pregnancy that it aches. Your mouth is the only thing that makes me feel better.”
Though his glasses were fogged up from the heat coming off Kinosaki’s belly and crotch, he could feel the cock in his mouth. Gero moved his head up and down, circling his tongue around the underside of the glans and caressing the veins along his shaft. It was only the two of them in the house right now. He could suck as loud and sloppy as he wanted. Loud slurps reached the ceiling, echoing back to Kinosaki’s ears as he saw the top of Gero’s head moving up and down on his member. He was lucky that his cock was so long, or he might not have seen it even when erect for the sheer size of his gravid belly. Kinosaki felt the pulsing of the blood flowing through his throbbing shaft, and his balls getting ready to release in Gero’s mouth.
Squeezing down on his breast, Kinosaki gave out a cute groan. A wet sound came from below his belly. Gero looked up. A line of semen connected the tip of Kinosaki’s dick to his lips. He slurped it up before swallowing, wiping the rest with his forearm. The remaining cum drizzled down his cock until it reached his aching balls. As the warm cum of his pregnant friend and partner made its way into his stomach, Gero lowered himself onto his knees once more. He put his lips between KInosaki’s testicles, kissing his balls as the hair on them tickled his nose. He took a deep whiff of Kinosaki’s musky cock, the smell having grown stronger with pregnancy.
Carefully holding his scrotum in his hands, Gero lifted it to reveal Kinosaki’s butthole. The hole had grown darker, and could open wider. It puckered and winked back at Gero, as if waiting to be filled with his cum. Gero unzipped his pants and unbuckled his belt. Kinosaki pulled down his boxers by the waistband, letting his cock spring out. Gero pressed his hard shaft against Kinosaki’s, lubing it with a mixture of Kinosaki’s cum and his own leaking precum. Their warm shafts rubbed together, balls squishing against each other as the two of them groaned under their breaths. Their hands clasped together as Gero lowered his cock, pressing the cockhead against Kinosaki’s anus.
“Fuck my pregnant boy-pussy,” Kinosaki said. “Papa.”
With two thrusts of his hips, Gero was able to squeeze his cock inside KInosaki. The already tight hole had gotten tighter still from the weight of Kinosaki’s pregnant belly pressing down on him. Kinosaki’s hole was lubed up enough for Gero to comfortably slide inside. He rocked his hips while heavily panting, listening to Kinosaki’s moans. Kinosaki was an actor by nature, able to convincingly fake emotions until the mark had given him what he needed. These moans weren’t fake. They were real gasps of pleasure from Gero sliding past his prostate, pushing deep inside his ass with his thick cock. Every push sent a wave of pleasure up his body, and made more spurts of milk leak from his erect nipples.
“I’m really having a hard time believing you’re a guy,” said Gero.
“Even with my hard cock in your face?” Kinosaki said. “That’s the spot. I’m feeling really good. Oh, fuck me!”
Each thrust of Gero’s cock inside him made Kinosaki’s gravid body shake. His balls shook beneath his swinging cock. Drops of warm semen were flicked away from his cock, landing on his swollen belly. The thrusts made Kinosaki’s stomach move up and down very slightly, and his milk-engorged breasts had a bit of wobble to them. For someone whose body had been slender and fit before, seeing parts of him turned round and soft and moving about was enticing. Gero thrust harder, pushing his cock as deep as it could inside Kinosaki’s tight asshole. Gero’s own balls were growing hotter, having held back on orgasming until he could unleash his load inside Kinosaki’s bottom.
“If you want another heir after this, I can give you more,” Kinosaki said. “You can breed me like you would one of your potential fiancees.”
“Would you really want to get pregnant again?” Gero asked.
“Being so round and bloated is making me hornier than I’ve ever been,” Kinosaki said. “I’d go through this all over again.”
Hearing Kinosaki whisper those sweet words made his cock pulse inside his colon. Gero unclasped his hands from Kinosaki’s, and moved them onto his supple thighs. Kinosaki’s thighs were drenched with sweat, a lot of it dripping from his balls and taint. Gero’s fingers slid further into Kinosaki’s thighs, moving closer to the pregnant man’s taint. He licked his fingers to coat them in warm saliva, and rubbed against the spot beneath Kinosaki’s engorged balls. His own cock was buried in Kinosaki’s ass up to the base. The two of them were so close they were exchanging body heat, so close to each other that Gero had never been more aware of the presence of a new life inside Kinosaki than he was at this moment.
Gently grazing his finger across Kinosaki’s taint pushed the femboy over the edge. Kinosaki’s throbbing cock shook back and forth without a single hand touching it, spraying a jet of cum into the air. The first rope launched upward and landed on Gero’s glasses, further obscuring the lens. His cock leaned back, spurting a second rope that landed on his belly. Kinosaki rubbed his hands across his stomach, soaking his own cum into his skin. He ran his finger up the shaft, gathering a glob of cum on the end of his fingertip before swallowing.
Gero pulled his own cock out of Kinosaki’s ass. He was panting heavily from the intense release of pent-up jizz that he had been storing. All of that off-white cum was now leaking from Kinosaki’s tight hole, falling off the edge of the couch and onto the floor. Kinosaki’s tight hole tried to close up, and only pushed out more cum. Kinosaki’s stomach was covered in warmth inside and outside. The smell of sweat, cum and milk hung heavy in the air. Kinosaki was panting, his belly and breasts heaving, with exhaustion. Gero turned around to get the two of them a drink from the kitchen. They would need to recover after that intense round.
When he turned around to leave, Kinosaki’s cock, nearly flaccid again, sprung back to life. It grew into a full and mighty rod at the sight of Gero’s ass. Kinosaki stood up, pushing himself off the couch. Lifting his heavy belly took some effort. The sound of Kinosaki’s breasts hitting his chest made Gero turn his head, followed by the sound of heavy panting. His body dripping, Kinosaki walked up behind the naked Gero and pressed his belly against the lower part of Gero’s back. His inverted navel rubbed against his skin while his cock nestled itself between Gero’s ass cheeks. Kinosaki wasn’t going to let him forget that even though he was the Poison Master, Kinosaki was his Cyrano de Bergerac, the one who was pulling the strings behind the scenes.
With a nudge of his belly, Gero’s hands pressed against the kitchen table. Kinosaki pulled back, giving himself some room. He lined up his cockhead with Gero’s ass, and stroked his flaccid cock with his other hand. The tip of Kinosaki’s dick popped in, followed by the upper part of his shaft. The familiar feeling of Gero’s hole wrapping around him made him stiffen, giving him the force needed to push in deeper. Gero felt Kinosaki’s cockhead scraping against his prostate, diving deep inside his ass until the only thing filling his bowels was that magnificent cock. Gero was fully erect, his cock slightly aching from the intensity of the orgasm only moments before.
“Let me rest my belly on your back,” Kinosaki said. “It’s so big.”
“Ki...Kinosaki,” Gero said with heavy breaths.
“Call me Mei,” Kinosaki said.
“Mei! Please be gentle,” said Gero.
“Okay, Hikaru,” said Kinosaki affectionately. “I’ll be gentle. But I warn you, I’m really horny, and it’s all your fault.”
Gero’s cock swung underneath the table as Kinosaki plunged deep inside him from behind. His long cock made wet noises as he pushed through Gero’s ass. A few months ago, it had taken some effort to get inside. Now Gero’s butthole was shaped into a perfect fit to be Kinosaki’s cock sleeve. Repeated fucking had turned it into his personal hole, and Kinosaki got hard every time he thought of that. He rocked his hips back and forth, rubbing the underside of his sweaty belly against Gero’s back. He stroked Gero’s cock, gathering some of the dripping semen on his palm and licking it off. Kinosaki loved cum, and he had swallowed so many loads in his mouth and ass over the past month. It was the thing he craved the most.
“I’m not going to get you pregnant too,” Kinosaki said. “I just want to wear out your ass until you beg me to go back inside.”
“It’s so... hard...” Gero said.
“And yet you endure it,” Kinosaki said. He raised his belly off of Gero before plopping it back down. The weight of his belly kept Gero pinned against the table. He wasn’t going to escape from above or below until Kinosaki was done having his way with him. Underneath Kinosaki’s stomach, his balls shook with sweaty motions. His cum was begging to be let loose. Kinosaki’s cute moans and Gero’s grunts melded together like their shared body heat, their heartbeats nearly synchronized to the sounds of their hard fucking. The stiffness of Kinosaki’s cock was matched only by the stiffness of his nipples. Every breath brought the smell of his hormone-infused sweat from his armpits, and his dripping breast milk, up to his nose. The smell of his own body was intoxicating.
Kinosaki released his hand from Gero’s erect cock. He massaged his breasts, moaning as his fingers pinched and tweaked his sensitive nipples. An audible, somewhat masculine groan came from Kinosaki. A powerful jet of hot, white milk sprayed from his nipple. The drops of hot milk fell across Gero’s back. He reacted like he had been hit with hot wax, even though the effect was more mild. Kinosaki sprayed more milk onto his back, and rubbing it in like a masseuse. He pulled Gero’s arms to lift him up, and squeezed his breasts against Gero’s back. Milk dribbled down, sliding into Gero’s ass crack and lubing up the repeated thrusts of KInosaki’s dick.
“Do you think you can endure much more?” Kinosaki said. “I want to finish inside you.”
“Let me cum...” Gero said.
“You’re not being honest,” Kinosaki said with a coy whisper.
“Mei, let me cum,” Gero said.
“Why?” asked Mei. “Or I’ll keep holding this naughty preggo body against you.”
“Because I... love you,” Gero said.
Kinosaki turned his head around. The two of them locked lips for a deep kiss. Their breath smelled like cum as their tongues tangled in each other’s mouths. The sensations between their bodies, buzzing with a greater intimacy and intensity than any poison could produce, seemed to fill the room. Kinosaki stroked Gero’s cum-soaked cock with his fingers, and gave a final push inside him. Kinosaki’s balls tensed up, and emptied a thick, gooey load of cum into Gero’s ass. Kinosaki quickly moved his hand upward, holding his palm against Gero’s spurting cock. When he pulled his hand away, strands of semen linked his hand to the shaft.
As Gero’s cock softened, he saw Kinosaki offering his finger to Gero. The bespectacled man sucked on Kinosaki’s finger, sucking his own freshly milked cum. He would have never thought to do this before, but Kinosaki’s pushing had made it common. After several more pumps, Kinosaki’s cock fell limply out of Gero’s asshole. It looked small and cute when it was soft, compared to the fleshy monster that had been inside him only moments ago. Kinosaki was still months away from giving birth, if such a thing was possible, and wanted to relax after they had gotten so much out of each other’s bodies.
A warm bath was drawn. Gero got in the hot water first. He had washed himself before entering, watching the last drops of Kinosaki’s cum and milk roll down into the drain. Kinosaki stepped in after him. The size of his baby bump caused the bath water to overflow, leaking out the sides of the tub. He backed up against Gero, rubbing his soft butt against his crotch under the water. Gero couldn’t get hard, even if he felt his cock twitching from the touch. He wrapped his arms around Kinosaki, rubbing his belly and groping his breasts from behind. Two small drops of milk leaked into the bath, turning part of the water cloudy and white.
“Don’t lactate in the bath. We just got cleaned up,” Gero said.
“If you keep teasing me like that, we’ll end up fucking in here too,” Kinosaki said.
“Again?” Gero asked.
“You’re the only one who can keep up with my sexual urges,” Kinosaki said. “I can’t wait to become parents with you. Now kiss me and rub my belly.”
Even with Kinosaki’s due date close, Gero hadn’t broken the news to his family. He had no idea how to explain it. This was something he wanted to keep enjoying with just the two of them. This miracle, this jewel of love that surpassed all common sense. Perhaps this was the purpose in life that he had been looking for.
