Bittersweet Sweetheart - Kotetsu/Barbie - For Sei!
((HAPPY BIRTHDAY SEI!! I'M SORRY THAT IT'S A FEW DAYS LATE!! ;_; DON'T HATE ME!
Kotetsu/Barbie, as requested.))
She's a brat; There's simply no other way to put it, and Kotetsu usually finds himself flustered around her.
If there is one thing he understands, it's 'pretty girl'. Barbie is pretty, gorgeous, in fact, with a hint of a diva complex, and he wonders how she even stands him most of the time with how he stammers and stutters around her. Condescending glares fall upon him, words of him being 'an incompetent old man' jab him in places he didn't know could hurt, and she does it all with a flick of long blonde hair over her shoulder and a sway of her hips as she saunters away from him on those too high heels that he tells her over again are going to snap. But Kotetsu is a good partner, and if they snap and she falls he'll catch her. It's just in his nature.
Then there are times, like now, where she looks at him like he's the single, most important thing in her life, green eyes blink hazy from the afterglow, pale skin shimmering in a sheen of sweat from being trapped between him and his mattress. Manicured nails on delicate hands comb through his damp hair and Barbie's lips part, leaning up for a kiss Kotetsu is more than willing to give her. The taste of strawberries linger on her, and he thinks that maybe she's just as bittersweet as the fruit itself the way she stains his tongue and melts under his touch. Forehead resting against hers he reaches up, brushing a rogue curl from her made-up face and smiles.
He doesn't need to tell her that he loves her, but he knows she likes to hear it anyway and whispers it breathlessly in her ear. The action earns him being pulled closer and Barbie nuzzles her cheek over his beard - which he also knows she secretly likes, no matter how much she patronizes him for it.
