Well as long as you don't physically touch her, you'll probably be able to.
At least that's been my experience. It's annoying, I think, "this girl's straight, but she's so cute and she's clinging to me innocently, but my feelings can't take it!" >///< It's sad really...
But luckily, from that blush reaction, Kino isn't straight. Which holding back at that point dang... It'll take a lot.
