Fatal kiss

Welcome, said the spider to the fly,
don't be shy.
Sit down, relax, let me caress you,
God bless you.
She wrapped all her black arms
around him
and the kiss she gave was simply
astounding.
He fell deeply in love with her.
He fell deeply into her
body? nest? Oh, what a quest,
black softness, soft thickness,
thick darkness, dark madness,
oh, the light is on but noone's home,
though the night is gone, you're all alone.
The awakening: will this end?
Well my friend, it depends:
can you do the spider again?
