Their friends watched silently with embarrassment, clueless as to what to do to stop the two children from bickering. It had all started rather innocently, the boys talking about kissing girls (once again, forgetting that Rukia wasn't exactly one of the guys no matter how much she pretended to be) and how they hoped that their first kisses would come soon.
With great pride Renji told them all that they were babies and that'd he'd already kissed plenty of girls. Revering their unofficial leader none of them thought to question his bold assertion, but Rukia just scoffed.
"If by plenty of girls you mean your hand pillow at night when you think everyone's sleeping."
That scoff had lead to the current bickering.
"I too have kissed a girl!" He yelled, small droplets of spit landing on Rukia's face in the process, she did not seem to care.
"Who then? Huh? Your mom?"
"N-no!" Anger and embarrassment painted Renji's cheeks a hue that rivaled his hair.
"You're lying, you've never kissed a girl, you don't have the balls-"
With that Renji's temper, and apparently impulse control, was gone. Roughly he grabbed Rukia by the shoulders and pulled their faces roughly together, half kiss and half head butt. With shock, Rukia just stood there as he continued pressing his mouth to hers.
As quickly as it happened he pulled away and smiled smugly to see her stunned silence. "You… uh, and others, of course. See guys I told you-"
"You call that a kiss!" Apparently Rukia's wits had returned. "That was pathetic!" In a huff the little girl stomped off and away from the boys who cheered for their leader, both excited by his bravery and jealous that they hadn't kissed her.
It took young Renji a lot to keep himself from following her immediately, but when he couldn't wait any longer he ran off after her. He found her, up a tree, looking pensive. She did not say anything as he climbed up to sit beside her.
"What do you want?" She asked, making a sour face and refusing to look at him.
Leaning over, in apology, he lightly put his lips over hers. It was gentle, sweet and private. He pulled away, smiling hopefully at her. "Was that better?"
Still mad she crossed her arms over her chest, pretending that her cheeks weren't just as red as his were. "I don't know… I couldn't tell, you'll have to try again."
