Keroro’s Father’s Day
       
       Outside of a local train station, a small, frog-like alien was fidgeting nervously with his bowtie and his hat. Trains and commuters passed him by without notice thanks to some advanced technology, and he was never more thankful to be cloaked than at this moment while he was nervously darting his head around to try and spot the frog he’d come there for. 
       
       “Stop fidgeting, sergeant. You’re messing up your bowtie!” A little blue frog skipped up to the sergeant and cheerfully reached out to adjust the tie. “You need to look good for your dad, right?”
       
       “Is he here!?” With a start, Keroro leapt away from his subordinate and scrambled to find his father, dashing between legs all around the station. 
       
       Tamama stared on in bewilderment while Keroro freaked out, skewing his tie in the process. “I hate to see him like this.” The smaller, blue frog twiddled his fingers and tapped a foot. “I know the demon sergeant is scary, but shouldn’t he be happy to see his dad on Father’s Day?”
       
       “He certainly should be.” A voice from behind Tamama made him jump. Anxiously, he glanced back to see a terrifying visage cloaked in shadow towering over him with a horrifying glare. The figure started moving closer, and with each inch Tamama felt himself sweating more and more. Eventually, it was right next to him. 
       
       Then, the shadow receded, revealing a small navy-green frog in a tie and helmet, staring absent-mindedly down at him. “Are you okay there, sport?”
       
       It took a few seconds before Tamama realized he was laying on the ground in a pool of his own sweat. Nervously, he lifted himself up and nodded. “Uh… y-yes, mister demon sergeant, sir.” He reached out a shaking hand and put on his big bright smile. “Nice to finally meet you.”
       
       Casually the old frog slapped Tamama’s hand away with a smile and the force of a truck. While Tamama winced and grabbed his arm as it went numb, the demon sergeant didn’t notice. “Well it’s nice of you to say so, private.” Without missing a beat, he stepped right around the stunned frog and started looking around the train station. “Now, have you seen that useless son of mine? He was supposed to be meeting me here.”
       
       Hearing his father in the distance, Keroro reacted immediately; rushing to him and standing at attention with a salute. Somehow in the rush, his bowtie ended up on his head. Tamama dashed to fix it as he spoke. “Right here, daddy, sir. H-happy Father’s Day, sir!”
       
       Keroro’s father laughed and waved his son down. “At ease, Keroro, at ease.” He patted his nervous son on the head. “This is just a friendly visit for the holiday remember.” He smiled warmly at his boy for just long enough for Keroro to chuckle back at him and lower his salute. Then, with a nod, a dark aura of menace subtly snuck up behind the older frog. His expression didn’t falter for a second, but the two younger frogs couldn’t help but stiffen as he spoke. “Now with that out of the way, where’s my present, son? I hear you’ve got some planet to share after all your hard work, right?”
       
       “I- that’s uh…” Keroro went wide-eyed as he struggled to respond. Thankfully, Tamama maintained enough composure to save him. 
       
       With vigor, Tamama grabbed Keroro by the shoulders and pushed him towards his father. “It’s right here, sir!” He shouted as he shook the sarge like he was displaying a shiny new toy. 
       
       Somehow, it must have worked, because the aura of terror receded shortly after the little display. The demon sergeant barely change expression though, only lifting his head slightly. “Oh, is that it?”
       
       “Y-yes, sir.” Keroro started to fiddle with his hands as he continued to stare wide-eyed at his father. “I just thought it’s been a while since we had some father-son time and that maybe you would appreciate spending a bit of time with me and that we could have a good time together and-“
       
       The demon sergeant laid a hand on his son’s head, cutting off the ramble and sending a shiver down Keroro’s spine. Then the old frog spoke. “Well, isn’t that sweet?” He smiled and took the hand down to his son’s bow tie. “And you even wrapped it for me. Very considerate, son.”
       
       Keroro’s spirit lifted quickly; his eyes filling with tears and his face turning beat red. He was practically glowing. “Th-thank you, sir!” He remained in that glow for a few solid seconds, even as his dad casually walked away and took a seat nearby. 
       
       Tamama was similarly engrossed in the glow of his precious sergeant. His concentration broke when he heard the demon sergeant’s call though. “Well, no sense in wasting time then. Are you joining us, private?” 
       
       “Oh, no, sir. I’m just here for moral su-” Tamama cheerfully turned to face the demon sergeant, and when he did, he froze solid mid-sentence. The old frog was seated against a nearby bench with his legs splayed and an absolutely massive erection in his hand. 
       
       His expression was as casual as ever as he smiled at Tamama and undid his tie. “That’s a shame.” Without missing a beat to react to the shock on the private’s face, the demon sergeant then turned to his son. “Alright then, Keroro. Dad’s ready for some bonding.”
       
       “R-right here, daddy?” Keroro slid into view with an eager look on his face and sparkling eyes. Then he blinked nervously. “You don’t want to go somewhere more-“
       
       Keroro was cut off when his father laid a hand on his head again. Though this time is was with much more force then a light pat. With stunning pressure, Keroro’s face was pushed against his father’s dick. It was slick against his skin, and with a few more affectionate shakes from his father, it left a streak of slime along his forehead. “I’m not sure I want to wait for that, son. You know your dad’s a busy frog.” 
       
       “Uh-uh-huh.” Keroro mumbled as he closed his eyes and nodded. Without waiting another moment, he let his tongue lose on the shaft. He started with a few licks at the base. Then, when his father started to loosen the pressure, he started to drag his tongue up the dick slowly. Years of aching shook his body as his own arousal started to slowly peak out.
       
       Keroro squeezed his legs together and shook his rear as he tried to contain himself and keep focused on his task. He let loose a whimper for a second before stuffing his mouth with the dick in front of him and slamming his eyes shut. From there, the only noises that escaped were the sloppy slurps as he sucked up his father’s pre-cum.  
       
       While his boy worked, the demon sergeant provided him with some affectionate petting, eventually working a hand down to softly caress his son’s neck. Calmly, he set his hand under the frog’s tie and turned it over in his hand until the bow rested in his palm. “My little present.” He sighed as he returned to petting the younger frog’s head. 
       
       “S-Sarge…” Tamama was staring stiffly at the scene all the while. His tadpole tail wagged, and he struggled to hide his own erection with his hands. Keroro was still bright red and teary-eyed as he suckled at his father’s cock, and Tamama couldn’t take his eyes off him. 
       
       A particularly weighty sigh from the older frog did draw his attention away briefly though. “Wow, Keroro, you’ve gotten a lot better at this.” Keroro paused for a second and swallowed. Then he started to suckle harder and bob faster. Before long he was fully deep throating the massive dick. “H-haaa!” The demon sergeant let out another sign and turned his smile to Tamama. “Has he been practicing hard since he got to Pekopon?”
       
       Tamama blushed and shook his head rapidly. A million thoughts of his sergeant filled his head. Most of them he’d had before, but now they were interspersed with pictures of the demon sergeant as well. Even with his experience in fantasy they were overwhelming. “N-no, sir!” he shouted as he tried to keep them at bay.
       
       A loud grunt managed to break him out of the fantasies just in time for him to realize he’d collapsed onto his knees. Surprised, he lifted his head to see the demon sergeant had thrown his head back, now shrouded by the shadow of the bench. “Stop, Keroro!” The voice shook with command and fury that froze Tamama solid and sent Keroro reeling. 
       
       Without delay Keroro pulled himself off his father’s cock and collapsed onto his back in terror. The demon sergeant rose and glared at his son through vicious, shining eyes. For a moment, Tamama considered rushing to his sergeant’s aid, but the aura that the older frog was letting off kept him squarely on his knees, and the massive dick between that old frog’s legs, still slick with saliva and dripping from its tip, kept him thoroughly aroused. 
       
       “D-daddy!” Without a word, Keroro’s father approached and lifted his son’s legs. Keroro shook to his very core as the demon’s shaft rubbed against a hip and slowly aligned with his asshole. He was sure that under his father’s shadowed eyes, he saw a smirk just briefly. Then, with a single thrust and a vicious grunt, the demon sergeant pressed the full length of himself into his son.
       
       Keroro’s scream as his father began to thrust rang loud enough that it startled the crowds in the station, and he didn’t quiet down after it was done either. Tamama felt tears come to his eyes as he felt the screams ringing in his ears. He couldn’t bring himself to look away though, watching the whole time as Keroro’s comparatively small cock bobbed against the stomach that was swelling with his father’s massive girth. 
       
       It wasn’t long before that swelling started to increase. With a vicious roar that sent the bystanders into a fright looking for the source, the demon sergeant let loose inside of the younger frog.  And with a “KERO!” to match it, Keroro came as well, sending his eyes rolling back in his head and slathering his face in sticky, white spunk. 
       
       Tamama didn’t realize he hadn’t blinked during the entire duration until it was over. As he watched the demon sergeant panting over his son’s leaking body, he finally blinked away the blur. When his eyes reopened, he saw the gentle, navy-green frog sighing and smiling contently over the well ruined Keroro. 
       
       “I’m impressed, Keroro. It’s been awhile since I used a hole that well.” There wasn’t much response from Keroro outside of twitch, but Tamama could have sworn that he saw his sergeant’s lips curl into a smile. Then, the demon sergeant turned to smile at him. “Still here, youngster?”
       
       Tamama nodded and pulled his hands closer to his crotch. A bit of fear struck him, worrying he might have offended the terrifying frog somehow. “S-sir, yes, sir!”
       
       The old frog nodded and tilted his head with a smile, casually rolling his eyes towards his son. “I suppose that’s no surprise. You want a turn now, am I right?”
       
       The question hit Tamama like a ton of bricks, but the moment he recovered from the resulting stupor he stood up and nodded as aggressively as possible. “Sir, yes, sir, yes, SIR!” he shouted. Then, blinking away some joyful tears, he turned his head up to smile at the sergeant. He was already gone.
       
       The young, blue frog felt a flipper on his shoulder before he knew what was happening, and a gruff, calm, and strangely chilling voice whispered in his ear. “I’m glad to hear it, son. I could go for another round.”
