Good to see you back Mephistopheles, it's been a while. I have to say it took me a few seconds to figure out what exactly was happening in that final scene, but I really like the novel method of dissection, as well as Ruby's enthusiasm; she's a fun character.

Does the (1) in the chapter mean there's going to be a follow-up (or, better yet, more than one)? I especially wouldn't mind seeing a solo scene with Ruby. Surely now that she's gotten a bit of experience she'd be eager to do some experimenting on her own when Alex isn't around. Perhaps work off some of her sexual frustration?

Looking forward to any future parts.
