TLDR;

-Vili reacts to her companions reactions
-Vili suggests a smaller thing for the girl's at her place.
-Vili guides white haired kitsune with her arm, lovingly XD
-Vili tells Lena to come along with her, looking to just get somewhere private for her own and her friend's sakes as well.

[@cloudystar] To be fair, that's not what Vili was thinking about.  But she did say something a little smaller for the girls, so she couldn't really say no to someone if they decided to hop along.
