Subaru had told his friends that he was going to the capital to visit Reinhard. Total lie. No one asked much, and he left with a silly smile on his face.
But there he was, outside the Karsten residence, hiding in the shadows of the night. I wasn't coming for Crusch, or anything political.
No, Subaru was coming for something much more... personal.
Something that had him sweating under his disguise.
Dressed like a cheap movie ninja, all in black, with clothes imported from Kararagi that were too big for him. He adjusted the balaclava that covered his face, smelling of new fabric and his own nervous excitement.
He took out his flip phone –that treasure of his world that no one in Lugunica understood– and plugged in the wired headphones, the last vestiges of his previous life.
They were like a talisman, reminding him that he was once a loser in Japan, not this stealthy madman in an isekai.
Press play. Mortal Kombat's Reptile theme filled his ears: that sinister, tribal rhythm, with drums that beat like a racing heart.
Subaru felt the rush.
"stealth stealth stealth", he muttered to himself, as if he were in a video game.
He crouched down, ready for action.
Using his parkour practices in the courtyard of Miload's mansion, he emerged from the alley, crossed the street, and scaled the walls like a real ninja.
His hands hooked into the cracks of stone, his feet stepping with ninja precision.
He hit a rope in the air, rolling like a pro, and fell softly into the bushes, rustling leaves but without a noise to alert anyone.
His heart was hammering, half fear, half adrenaline rush.
He slipped through the guards, zigzagging like a shadow, holding back his laughter.
He took out his Mark-2 model whip –an improvised gadget with rope and a hook that he nicknamed with a technological name because it sounded cooler– and threw it with precision, hooking himself to the high wall of the mansion.
He pulled it, climbing agilely with parkour: a jump here, a foot on a bump there, muscles burning but mind in war mode.
He reached the window, panting softly, and sneaked inside.
Finally, he had arrived.
Felix's room.
Subaru moved within with extreme secrecy.
And there he was: Félix, lying face down on his bed, like the neko femboy that he was.
Her Neko UwU Kawai tail almost wagged in her sleep, her hair messy on the pillow, her body thin and curvy wrapped in a light camisole.
Subaru stopped, admiring the scene. Félix was pure innocent temptation: skin pale as milk, hips that curved just enough, and that round butt that looked temptingly under the fabric of some pretty pink panties.
Subaru rubbed his hands, an evil gesture that was so bad, and licked his lips behind his balaclava, savoring that femboy ass in advance.
He approached stealthily, step by step. Felix didn't even flinch, snoring softly like an exhausted kitten after a day of magical healing.
Subaru extended his hand, shaking a little with emotion, and pulled down Felix's panties without him noticing.
Subaru slid them in slowly, revealing that perfect, pink, and most likely tight ass.
The fresh air brushed against the exposed skin, and Subaru smelled that feline, sweet aroma that always drove him crazy.
Then, Subaru urgently unbuttoned his ninja pants.
He took out his huge cock, long and thick like the forearm of an adult man, veiny and throbbing, his head swollen and red like a ripe cherry, already dripping with a thread of precum that shone under the moonlight.
He was a monster, disproportionate to his skinny body, but at the time, it was his secret isekai weapon.
He held it, rubbing it against his palm for a second to lubricate it with his own moisture, already imagining how it would sink into that little femboy ass.
When he finished the preparations he made a ninja rope to fall into bed with extreme stealth –spinning epically in the air, landing without creaking a single feather from the mattress.
He leaned over Felix, his friend Neko's body warm and soft beneath him.
He quickly lined up his thick cock with that virgin and pink entrance.
He pushed stealthily pro, inch by inch, feeling the tight ring resist at first, but still giving in to his punishing male cock.
Felix's interior was like a delicious oven, soft, hot walls that instinctively contracted around his cock, sucking as if they wanted him deeper.
Subaru stifled a moan, biting his lip under the mask, and began pumping it:
Slow attacks at the beginning, stealthy, each one sinking that monstrous cock deeper, stretching the narrow channel to impossible limits.
The pace accelerated.
Subaru rocked precisely, but his cock was already splashing with wet sounds.
Each descent was an obscene delight –the thick base rubbing against the sensitive skin, the heavy balls beating rhythmically against Felix's, which hung loose and vulnerable.
Subaru felt the heat rise, his femboy ass tightening in involuntary spasms, milking him like an anxious mouth.
Sweat dripped down his back, mixing with the musky aroma of impromptu sex, and he imagined what it would look like from the outside: a maniacal ninja fucking Crusch's sleeping gentleman.
"~Nya...".
At one point, Felix seemed to want to wake up, a soft moan escaping his parted lips, his feline ears almost trembling.
But being a ninja pro, Subaru was more than prepared.
He took out the homemade cat grass that he made himself, and threw it on the back of his neck with a ninja blow.
Pieces of grass scattered on the back of his neck and pillow, and Felix sank deeper into sleep, purring softly like an anesthetized kitten, his body relaxing even more around the intruding cock.
Subaru pumped harder now, unchecked, pleasure building up at his base like a storm: each thrust made his glans brush against that sensitive prostate, sending waves of sleeping ecstasy through Felix, even though he didn't know it.
The femboy moved a little, hips rising instinctively, his own small cock hardening against the sheets, dripping wet spots in an involuntary erotic dream.
Subaru was approaching its limit, the Reptile theme beating in his ears like a countdown.
"Ninja Cum", he said in a ninja whisper, voice muffled and triumphant.
And he came.
Lines and lines of thick, hot, sticky semen gushed from his swollen cock, flooding Felix's insides in powerful jets that filled him to overflowing.
Each pulse was obscene: the first jet hitting deep, painting the inner walls creamy white; the second, third, fourth, fifth and sixth mixing with the rest, slightly swelling Felix's flat stomach with an abundant load.
He gasped, trembling, feeling Felix's ass twitch in spasms, squeezing every last drop, leaving a hot, wet mess that would slowly seep in for hours.
When he finished, Subaru came out of him with a sucked pop, his cock still dripping white debris onto the sheets.
He carefully put her panties back on her ninja, covering her ass.
He gave bro's affectionate pats on the right buttock.
He then put the penis, still half-erect and shiny, into his ninja pants, adjusting it with a satisfied smile behind the balaclava.
At that moment, the door slammed open.
It was Wilhelm, the old swordsman with his usual stoic expression. "Félix-dono, there are signs of intruders, quickly, we have to-", he cut himself short.
His eyes widened when he saw him there: the masked ninja on the bed, the air filled with the smell of fresh sex, Félix still asleep with crooked panties and a suspicious blush on his cheeks.
Subaru didn't wait..
He threw a rope back, going out the window in an acrobatic turn.
He fell ninja style –rolling on the grass, jumping up–, and ran away squeezing his buttocks.
Behind him, Crusch's soldiers shouted alarms, shooting him with bows and javelins that whistled near his head.
An arrow grazed his balaclava, another stabbing into the ground where he had been a second before.
But he zigzagged, dodging everything, laughing hysterically inside.
He managed to cross the wall with Pro Master agility –a final jump, clinging to the top and turning to the other side–, falling on his ass on the cobblestone floor.
It hurt, but it was worth it.
So crazy.
And there, on the dark street, came Patrasche, also dressed as a ninja –in reality, covered in black sheets that Subaru had clumsily tied to her before, she looked ridiculous, snorting confused but loyal.
Subaru jumped on it, clinging to the scales under the cloth, and escaped. The wind whipping his costume as the Reptile theme came to an end in the headphones.
Back at the residence, Felix woke up slowly, blinking with his neko uwu eyes.
Her stomach felt full and her ass all sticky, a thick, moist heat seeping through her panties, as if someone had spilled hot honey inside it.
He shifted, confused, shyly touching himself and sticking out his shiny fingers of white, slimy residue. "What... What happened?" he murmured innocently, blushing up to his ears, while a pleasant tingle ran through his body.
Wilhelm, all traumatized, froze at the door, his sword half drawn, his mind reproducing the obscene scene again and again: the intruder, the messy bed, the unmistakable smell. He coughed, red as a tomato, and turned around quickly. "N-nothing, Félix-dono. Just... a bad dream. Go back to sleep." But in his head, the old swordsman swore revenge against that horny ninja who had dared to attack his partner.
Subaru, meanwhile, rode toward freedom, planning his next "mission" with a smile from ear to ear.
