Writing on the train is soothing

I've been trying to write an Ivy/Rachel scene in my head using Sapphic Metre, but I'm having trouble joining together the Ivy part to the Rachel part. Here's what I have so far, anyway.

I'm doomed to darkness, blood-sated but love-starved.
Salt filled circles won't save you from my hunger.
The dark flood rises, ancient and primal as
The spilling of blood.

Warm breath on my neck, your leg between my thighs -
I see in black reflection myself ensnared.
Deceive my senses, ignite in me a need
Infinitely lost.
