[So there's an upgrade out to the agony beam, the Origin Jokers came up with it,] Bella informs Sherlock, [and I know I never actually use my agony beam, but I went ahead and got the new version anyway.] There is a suggestive lilt to her tone, not that she'd have to deliberately put one there for him to notice it.
[New version is called a 'sensory synth'. All kinds of fun features. I am pretty sure it is sophisticated enough that if you wanted you could try a convincing facsimile of my favorite thing.]
[I thought so! And there are other pleasing un-agony-beam-like applications - Pattern recommends using it like a sustain pedal on a piano - but that was the first thing that came to mind when I heard it.]
[Excellent.] Pause. [I have two hours before I have to go to school for Charlie-placation.] (It is currently five in the morning. Sleep? What sleep?)
And she takes aim with her synth, though that is all she does without explicit invitation.
And then she touches her teeth to his skin, and carries on by magic, from memory.
[Isn't it?] She carries on, hugging him tight, nibbling gently with her real teeth while she duplicates Her Favorite Thing with synth ones. [It feels like it doesn't make sense for it to feel good but it does it anyway. Emphatically.]
Nibble nibble snuggle snuggle. This can go on a while; she has some rather lengthy biting memories to pass along since she stopped having to worry about blood loss.
