Possessive from both ends, but Donnie acts innocent 🤭
Donatello had been aching to do something. Anything his mind would let him, he'd been sitting in his lab for a while, tapping his pencil as he stared at the unfinished code on the warm screen infront of him. Eyes a bit bloodshot and heavy from the hours of denied sleep, he finally gave in and closed his computer. As he stumbled to the couch in his lab, he got a notification on his phone? Ugh.. of course his menace younger brother was up still, and stupid enough to text in the group chat that he was hanging out with his Casey.
...
His? Wait. Where'd that come from? And, why was he jealous? He must be MUCH more tired then he initially thought-?
"his Casey" why would he care for some idiot vigilante anyway? Stupid. Donatello huffed as he crashed against his couch.. sinking into the cousins as the quiet night pulled him into slumber.
This was only one of a couple times Donnie had felt his gut twist in a knot the very same way, even snapping at his brothers briefly when they got to close, then brushed it off as stress. But it only got worse as the hockey player started playing along, teasing and messing with the poor turtle,
One evening it was taken a bit far..
"Would you stop pulling on my bandanna?? Seriously Jones. It's not even funny!!" Donnie snapped at Casey, then yelped as he was yanked back by said bandana "come on, it's just harmless fun~" Casey basically purred as his tone was playful and teasing. Donnie's eye twitched as he glared up at Casey, his head tilted back as he was sitting in his chair, while Casey was standing behind him, leaning against the chair with a smirk. Donnie glared up at Casey as he complained again about the boy's poor manners, when Casey cut off Donnie with a scoff "Donnie, do you do anything but talk and complain?" Donnie gasped "Oh!? So that's how it's gonna be!?? Well then- genius. why haven't you left? Let alone shut me up yourself. I bet your stalling! You're existence is basically just to annoy me-!" As Donnie continued blabbing on and rambling.. Casey found himself staring, the dork had a point, and his lips where right there...... talking still. It's not like he's thought about it before or anything. Eh, what's he got to lose? Casey pressed his hand against Donnie's neck to tilt his attention back to him and Donnie went quiet but still muttered, but before he could ask-
...
...
His lips, a bit chapped and rough feeling to the touch.. but intention soft and meaningful, Donnie froze, absolutely stunned as he clenched his fists at the edge of his chair rests and eyes widened, face burning as he practically heard his racing heart in his ears. Ringing loudly like a cymbal clashing in his head. his brain yelling to pull away, but he didn't want to.. his hand trembled up to reach when Casey pulled away, his alarm going off "awe, darn. Sorry Tello~ guess I have to go-" Donnie yanked Casey back down "no. You are not just leaving-!" Donnie huffed, while Casey raised a brow "why not?" Casey hummed Donnie fighting to come up with something to keep him to stay.. "cause.. it's wrong...." they stared at each other before Casey snorted "Wrong?" He echoed with amusement "y-yea. Cause- you have no reason to be out right now." "Don, it's like 10 pm and my house is far away-" "stay the night." Donnie stated like it was obvious. Casey froze them smirked "you want me to?~" Donnie didn't say yes, ... but he didn't decline it either "shush."
