My sister boasted to me one night in a Liverpool pub
She had *** with a couple of coppers down the Mersey Tunnel.
'You're nothing bit a fat slapper' I scolded her,
As she examined the selfie I had taken
Just a few moments earlier of me
And her best friend up against the ladies' bog door.
"Good likeness, innit?" I commented and the
She farted stentoriously in surprise and,
The follow-through oozed down her dimpled thigh.
