When He Smells His Brother on You (Rise ver.)

A/N: Scent marking headcanon scenarios, anyone? š Anyway, Happy Thanksgiving? š
CWs: Possessive/territorial behavior, scent marking, the guys acting a bit feral. Considering the subject matter, itās not a stretch to say that these may be somewhat NSFW, but not super explicit. All characters are aged-up.
LEO
Leo is lounging on the edge of the skate ramp, tossing one of his katanas in the air with practiced, bored ease. When he sees you enter, he flashes you that classic cocky grin. But the sword fumbles in his grip the second the wind shifts.
The silence that follows is deafening.
He drops from the ramp, landing silently, moving with the fluid grace of a red-eared slider. But the water is turbulent today. His eyes narrow, scanning you, zeroing in on the collar of your shirt. He smells his twin.
āDonnie?ā he asks, though itās not really a question. His voice is light, but thereās a razor blade hidden in the tone.
He circles you like a shark in open water. He stops behind you, and you feel his hand clamp on your shoulder, trapping you in place. Then, he slides both hands under your jacket, pulling you back against his chest. He noses at your hairline, inhaling the scent of his twin, and gives a mocking scoff.
āBoring,ā he whispers, his lips grazing your earlobe.
He spins you around, pinning you with a look of intense, possessive heat. He drags his nose along your jawline, rubbing his cheek against yours, effectively wiping away the other scent. His hands wander lower, cupping you, pulling your hips against his to make you feel exactly how jealous he is.
āIām going to ruin you for him,ā Leo promises, his voice a sultry purr. āBy the time Iām done with you, the only name youāll be screaming is mine.ā
He kisses you then, demanding and deep, intent on marking every inch of you until the scent of his brother is nothing but a distant memory.
RAPH
The moment you step into the lair, the air in the main atrium grows heavy.
Raph emerges from the projector room. He doesnāt greet you with his usual teddy bear warmth and snaggle-toothed grin. Instead, his nostrils flare, and a low rumble starts deep in his plastron. He stops inches from you, his shadow swallowing you whole.
āLeo,ā he grunts. He doesnāt ask; he knows. The scent of his brother is a stain on your neck, a neon sign of a challenge.
Before you can explain, his large hand encases your shoulder. He crowds you against the nearest wall, his size effectively caging you in. Raph is an alligator snapping turtleāa creature of instinct and force. And right now, his pupils are blown wide, eclipsing his normally kind irises.
He leans down, burying his snout into the junction of your neck and shoulder, inhaling deeply before letting out a sharp, angry hiss. āHe thinks heās slick,ā he growls against your skin. āLeaving his mark on you like he owns you.ā
He nuzzles you, the texture of his skin scraping deliciously against your pulse point, replacing the lingering trace of Leo with his own scent. He bites down gently on your neck, just enough to make you gasp, his tongue swiping hot and wet over the spot immediately after.
āIām gonna cover you in so much of me that youāll forget he even exists.ā
He pulls back just enough to look you in the eye, his gaze dark and hungry. Raph intends to stake his claim so deep inside you that no amount of scrubbing will ever wash him away.
DONNIE
The lab is loud with the sound of welding and music, but the moment the sensors at the door recognize your biometrics, the noise cuts out instantly.
Donnie spins in his chair, a rare, genuine smile formingāuntil he smells it. His smile flatlines. He stands up slowly, the mechanical spider limbs of his battle shell unfurling from his back, betraying the agitation heās trying to suppress.
He smells the chaotic, vibrant scent of his younger brother all over you. Itās messy. Itās loud. Itās incorrect.
āCalculated probability of you visiting Michael before me was low,ā Donnie states, his voice monotone, masking a brewing storm of possessive rage. He walks toward you, his movements stiff. āAnd yet, here you are. Contaminated.ā
His hands clamp onto your waist and shoulder, pulling you closer. He examines you, leaning in and sniffing the air around your neck with clinical precision, his face twisting in distaste. Then he cups your face, his thumbs stroking your cheekbones.
āI donāt like sharing,ā he murmurs, his eyes dark and dilated, āand I certainly donāt like sharing you.ā
As he presses his forehead against yours, his battle shell disengages and retreats back to storage, revealing the soft shell underneath. He begins to kiss down your throat, methodical and wet, placing suction bites in a perfect geometric pattern over the areas where Mikeyās scent is strongest.
āIām going to conduct a thorough recalibration,ā Donnie breathes against your skin, his arm sliding down to tease the hem of your pants. āWe arenāt leaving this lab until your biometric readings are exclusively synchronized with mine.ā
MIKEY
You expect a flying tackle-hug and a loud āOmigosh!ā Instead, when you walk into the kitchen where Mikey is cooking, he freezes mid-chop. The knife lowers slowly to the cutting board.
The playful box turtle vibe evaporates, replaced by an uncharacteristically terrifying stillness.
Mikey turns around. Heās not smiling. His face is blank, eerily calm, which is infinitely scarier than him yelling. He smells Raph on you, and it triggers a primal, bratty defiance in him. He walks over to you, wiping his hands on his apron.
āYou smell like Raph,ā he states. His voice is soft, but it lacks its usual bounce. Itās deep, flat, and laced with possessiveness. āWhy do you smell like Raph, angel?ā
He wraps his arms around your waist, burying his face in your neck, inhaling deeply. Then, he tightens his grip. He looks at you, his eyes wide and pitiful, but underneath that puppy-dog look is a feral gleam.
āDid he touch you?ā he asks, his hands wandering, gripping your rear firmly, pulling you into his hips. āDid he think he could just take you? Because heās the biggest?ā
He lets out a low growl. He hates it. Hates that his brotherās scent is clinging to his person.
Suddenly, he spins you around and hoists you up onto the kitchen island. He steps between your legs instantly, prying your knees apart with his thighs to settle himself firmly against your center.
āI hate it,ā he hisses, again burying his face into the crook of your neck, inhaling sharply before dragging his teeth over the sensitive skin there. He rubs his cheek aggressively against your chest, your neck, your jaw, acting like a cat thatās terrified of losing its territory.
āWe arenāt leaving this kitchen,ā he vows, ānot until I know that the next time Raph walks by you, all he smells is me.ā
