NUMBER ONE
This is number one
And the fun has just begun
Roll me over, lay me down and do it again
(I like the feeling)
Roll me over, in the clover,
Roll me over, lay me down
And do it again.
This is number two
And my hand is on her shoe
Roll me…
This is number three
And my hand is on her knee
Roll me…
This is number four
And her clothes are on the floor
Roll me…
This is number five
And the girl is still alive
Roll me…
This is number six
And she’s wild about my tricks
Roll me…
This is number seven
And we feel just like in heaven
Roll me…
This is number eight
And she cries “I cannot wait”
Roll me…
This is number nine
And I take her from behind
Roll me…
This is number ten
And I use my fountain pen
Roll me…
This is number eleven
And she says “again from seven”
Roll me…
This is number twelve
And she says “do it yourself”
Roll me…
This is number thirteen
And we dry ourselves in the curtain
Roll me…
This is number twenty
And my gun is getting empty
Roll me…
This is number thirty
And the story’s getting dirty
Roll me…
This is number hundred
And the neighbours really wondered
Roll me…
This is number 10 394
And she still wants some more
Roll me…
some more will continue when i have the time to type them up
