Saw this on another board recently https://bunkerchan.xyz/anime/res/101.html#5588 and, while it's a bit more graphic than I'd like, I thought it would work for Eva/Alyssa as well, with minimal modification.

I wake up in the morning
And I raise my sleepy head
I've got your soft breast for a pillow
In your arms was last night's bed
My queen knows where we're going
Only we know where we've been
I'm your partner on this road
Your faithful lover
An anchor in your wind
When we're brought into this world
They say we're born in sin
But our feelings for each other
Are far too strong to ever dim
Well they tell us that we're tainted
But if this is tainted then
I don't care for their morals
This is the purest love for us
Just try to stop us if they can
I'm going down in a blaze of glory
Feed me now but know the truth
I'm going down in a blaze of glory
Lyss' I'll never not want
Your taste on my tongue
You're my only one
Feed me your cunt
They ask about our conscience
And I offer you my soul
They ask of conjured spirits
Yours is the spirit I adore
You ask me if I can taste love
And if I like to lick you in the rain
Well, I've made my love come
And I've felt you sag down
I've held you when you came
Come now in a blaze of glory
Feed me now but know the truth
I'm going down in a blaze of glory
Lyss' I'll never not want
Your taste on my tongue
You're my precious one
Feed me your cunt
Each night we go to bed
I pray my queen my soul to keep
No I ain't looking just for pleasure
But before we go to sleep
Lyss', I got to ask a favor
And I hope You'll understand
'Cause I'll always crave your nectar
Let me taste you without end
Staring at your petals
Let me lick you where you stand
Come now in a blaze of glory
Feed me now but know the truth
I'm going down in a blaze of glory
Lyss' I'll never not want
Your taste on my tongue
You're my only one
Feed me your cunt
