Liiza was too angry, jealous, and busy thinking of what to do with those green lips to realize they had landed on hers.
Moreover, that situation was similar to what Khan had experienced on Merth 290 with the annoying Orlats. Jenna couldn't count as a threat to Liiza. The entire group of Nele couldn't, so Liiza disregarded their actions.
That changed when Jenna kissed Liiza. The latter widened her eyes in surprise, finally realizing what was happening. She instinctively pulled her head back, only for warm arms to wrap themselves around her neck, locking her in that intimate moment.
Liiza wasn't alone in her surprise. The group of Nele had forgotten about the ice around their feet and stared at the scene with wide eyes. Touching someone was a big deal for them, but a proper kiss surpassed their wildest expectations. They knew Jenna had been quirky in the past, but that still sounded to be too much.
