I don't think they had sex. I think they just cuddled, since they both had their clothes on.
This was my initial interpretation as well, that the middle panel on 29 immediately follows the top panel. This fits narratively as well, as Yuriko is learning to cherish Koro's presence itself and not just use her for her own needs.
But on reexamination, I think the people here have it right. If she's meant to be clutching Koro in that panel the position of her hand makes no sense, and the flowers are suspect. As poor a way to convey it as it is, I think that's intended as a one-panel sex scene.
If true this drops the story from one I'm fairly fond of to basically a zero for me. There's no character redemption. It's just a dumb story about a bad lady.
