Well, [she tilts her head again] most of the sketches I saw were just the breasts at rest, right? The kind of thing you could draw by seeing them... [Relm could have drawn those from looking at her, or their mother, or models in swimsuits.]

[Surely, her would be the first bare breasts Relm had seen since she was breastfed but she's greedy. She wants more and more and to take more "firsts" from her sister. She shifts ever so slightly, feeling her own forbidden excitement. Even if her greed backfired and she were kicked out, she could probably just retreat to her room with a toy. She probably could have done that from the second she heard Relm's gasping through the door. The sight she'd managed to catch was already worth it, though.]

I wouldn't suggest draping anything over them but... What about resting something in-between them? [her eyes flick down again and she looks back up quickly, not wanting to be caught] ... like a water bottle, or maybe one of your brushes? That's something you don't see as often, right?

Or, [don't sound too eager, don't let it show,] if we were to drip something on top to make them shine? [to make them slippery, more inviting, easier to imagine sliding between]
