Thanks for this fun contest, papa-pepper. Here's mine:

Dear blue Peggy Sue,
sweet robot girlfriend, precious metal boo
with our steem-powered rocket we day trip the ’verse
you tend to my needs, a right naughty nurse
I’m a king on a throne when you rub down my feet
I wish I could build a blue girl-bot fleet
outside our rocket, a sun starts to blow
but inside, damn, I feel your love circuits glow.
