[Rise seems to have a way of putting Natsuru at ease, enough that the taller girl doesn't think twice about sitting on the same couch next to her. Though, she still blushes and folds her hands firmly in her lap to keep her 'problem' a bit more hidden.]

I'm usually better at it! Most clothes don't fit or look right if I don't keep everything tucked away, and it only ever comes undone when I can't stop thinking about... things...

[Her blush grows deeper again, and her head turns ever so slightly away from Rise. It suddenly hit her how frankly she was talking about her erection with the girl who she was thinking about to cause it. Yeah, they're both idols talking about a practical issue, but also... she can't just admit the thoughts she's been having to Rise Kujikawa!]

O-Once it calms down, I'll be able to fix it. It'll be fine!

[She says, while fidgeting with her hands in her lap and squirming a little. Because it is not easing in the slightest.]
