"It wasn't supposed to happen like that."
He may have been thinking about this a lot. But since he is the one considering it, it is up to him to initiate or not.
He means to (meant to). Right now he isn't prepared for it. Maybe that's why Seiji decides to steal this aggravatingly curious idea from him. It must have been easy for him to discern. All that was left was to tilt a shy cheek, and press lips onto the other's.
Shuuichi couldn't even imagine what would happen afterward. But he is able to breathe fully, freshly, and try for himself.
From that reciprocation, something stirs inside Seiji to press more tenderly. Pressed back, they both delight in the other's labored breathing and curious lips. It would be easier at his home, Shuuichi thinks when his head bangs against the wooden pillar. He at least has a sofa.
Although he considers himself paced, Shuuichi finds himself breathless, unable to catch up to Seiji's passion (but this time he doesn't mind). It ends too quickly. (Still shy on both ends to push, to try further.) The older wonders if he would have continued, but with Seiji's withdrawal, he knows not to press. He feels a puff against his face. Upon opening his eyes, Shuuichi sees Seiji's bright satisfaction etched into his grin – no doubt because of the senior's dishevelment.
Nipping under the sandy-blond's jaw, the young exorcist grasps his attention once more. "I liked that," he purrs, waiting on Shuuichi's reaction–
–or what he could have seen of it before said teen tilts his head away, covering his mouth with the back of his hand. From the glimpse he is able to get, it's nice to see the flush still on him. Seiji settles himself against Shuuichi's chest, head nestled and black hair tickling the other's neck, smile both smug and content.
"It wasn't supposed to happen like that," Shuuichi quickly blurts out. (It was his idea, he repeats to himself. Then again, admitting something like that is extremely embarrassing. Why would he want to take the credit?)
Seiji blinks widely and tilts his head up, unsure of what he heard. "What?"
Shuuichi frowns to himself despite his lips wanting to quirk up. The wetness of the kiss gradually leaves him and he's too embarrassed to ask for another.
Seiji also notices (of course he does) and presses their lips once more. (The right amount of exciting pressure. One shaky breath and the other relieved.) "Just ask if you want another." There's a laugh so quiet that it would have gone unnoticed if it wasn't for Shuuichi's intuition with the younger teen.
The sandy-blond half-heartedly shoves Seiji, resulting in an actual laugh this time. He pointedly ignores both the teen and the pout pulling on his lips, looking to the forest bordering the Matoba estate.
He keeps stealing from him.
