Rum-Pum-Pum

I'll stick my fingers up my rum-pum-pum-pum
And then massage my prostate with my thumb
It makes me piss my pants and twitch my nuts numb
And up my anal-hole you'll find bubblegum
Why don't you sum fresh for my bum
My large intestines smeared with c-c-c-cum
I think my roommate Lance, deposited some
Much better there than in my cummie-cum-cum
I'll douch my anal par with a bottle o' Rum
With my cup-cum, here in the slum
With my thumb up my bum
