Many bogs-blokes' worlds collapsed,
After mum catastrophically prolapsed.
dad's hobbies: mountain treks,
and entertaining blokes "below decks"
(penis shape: convex)
Mum's sticking with the usual plan,
Of getting bum-fucked by every possible gentleman.
Dad doesn't appear to fear any possible consequences,
For his relentless, attempted and completed, catalogue of sex-offences.
The one advantage of your dad's limited dong is that it allows him the room to to wear his favourite ladies thong; disease and bad genes have ensured his penis is almost totally gone.
There's no part of your mum that could be termed 'uncharted territory',
Your dad in 'Bad Cock Weekly': He's the lead story.
One doesn't need to be Nostradamus,
To foresee a bleak future for mum's anus.
Mum and about 85 blokes have just wrapped on a "video nasty",
But alas, mum's entire fee needed to pay for yet another "anus-o-plasty".
Mum's prepared one of her famous 'Welsh rarebits'
(That's right, a load of coal miners' spunk applied liberally over her baretits)
Blokes complain of things getting a bit 'uncanny valley'
Looking directly up mum's abysmal 'poo-alley'.
