[And down they go! It doesn't take much more than that to get her to go along with it, really, and she does her best to keep Momo close the whole way; one of Jiro's hands slips up to curl around the back of her head beneath her ponytail, giving her a little leverage to press up into that kiss just a bit more.
And with Momo's legs finding a space between her own, she's plenty happy to move and shift to make it more comfortable - namely, of course, spreading her knees to make room for her, one of her legs bending up to plant her heel on the mattress.

Once they pull apart, though, her hold loosens just a bit, with her thumb softly rubbing right behind Momo's ear. It's a pretty fond touch, too.]

What, like my other smiles aren't?

[Based on the tone - and the fact that she follows it up by pressing a little kiss against Momo's cheek with a light hum of a laugh - she's pretty obviously teasing her.
... But the whole of it is just cementing that blush where it is across her features, and man, she can almost feel how warm her face is right now.
Momo's lucky she blushes easily if she really finds it that cute.]

I'm just... so happy, right now. You just make me so happy, Yaomomo.
I know that probably sounds a little cheesy coming from me, though...
