For his slim build, Hinagiku found that Arthur felt surprisingly sturdy as a point to lean against. Briefly she wondered if right now embracing, Arthur in this situation gave the same comfort as a safety blanket, something to hold onto, but more importantly was how welcome his touch was in return. It was something she could settle into, his hands on her back, and she only wished that he'd perhaps hold her with some more ferocity and strength. Had the mood been different perhaps Hinagiku would tell him as much, to not pussyfoot around and really hold her tight - but not now. For now it was enough like this.
Her eyes stay shut for a long time, simply and quietly enjoying the moment of quiet and comfort, and she's roused from her relaxed state first when Arthur starts to move away. Unwilling to end the contact, but unsure of a way to prolong it, Hinagiku moves her hands to Arthur's shoulders as he leans back, moving her head away to look back at him. Quietly she stares with her cool and calm stare, but the pink in her cheeks and ears betray her, even though Hinagiku is hardly aware or comprehending the faint emotion that's bubbling inside of her right now.
Arthur moves closer, and Hinagiku doesn't realize what's happening. He moves closer still, and she doesn't understand until his face is so ridiculously close to hers that there's really only one way for this to go. It's a kiss, isn't it? Hinagiku knows what it is, and she knows what you're meant to do but his mouth is on hers and she can't do much more but close her eyes and stay still. Steadily she grows more and more aware of how heavily her heart is beating and how her stomach is fluttering and how pleasant this is - and like the hug, it's over all too soon with no more input from her side than sitting still like a statue.
Unlike the hug, she knows how to continue this.
"...Ah liked that, Attur." She states simply, after a moment of staring at him and smiles, almost a bit wryly, as she draws herself up slightly on her knees to equalize their height difference. "Ah liked that a lot." And grasping Arthur's shoulders tightly for balance, she leaned down towards his face from her new elevated position and pressed her lips against his with much more certainty and force - but with at least as much clumsiness.
