The last verse is so sudden and final that it provokes a burst of laughter in me. An elegant construction Bilbo, vulgar and cynical.
This may be a personal thing, but I think the profanity in L2 would work better inbetween "ginger" and "tom".
A couple of grammatical nits:
* "Slung between his legs; just
beneath his arse, queens would swoon."
These lines seem oddly arranged. How about:
"Slung between his legs, just
beneath his arse; queens would swoon."
*"Storms" needs an apostrophe as it's being used in the possessive context.
Does "Again" need a comma after it? It might improve the rhythm if you cut it out. For me, anyway.
Thanks for the read, Bilbo
