Thank you, sozobe.
Looks likes we're stuck in stage 2, with everything happening in that stage except the licking of her vulva. I really don't think there would be any way for her to reach it if she felt the urge.
She's sitting up, then down, napping occasionally. Doesn't appear too exhausted yet.
I guess we'll wait a little longer. Looks like she could have done this during office hours, though.
