Jester tries to get over her hesitancy about asking questions related to sex and letting people know she doesn’t know everything.

Beau wants to make sure she feels like she can ask.

Jester asks more and more invasive questions, including what certain things feel like etc.
Eventually she and Beau end up trying a few things out, first in a very hands off way and then more involved stuff.

Jester doesn’t realise just how severely Beau’s caught feelings for her, as she doesn’t see sex as necessarily romantic and she knows Beau doesn’t either.
Beau is caught because she wants to do those things with Jester but doesn’t want them just to be romance-less exploration. She does some things and then feels sad/guilty/hurt by the situation, but hides it from Jester until someone notices and it has to be resolved.

Cue hurt/comfort scenes, maybe comfort sex.
