Swinging back and forth...
rocking back and forth
Rocking back and forth on my toy
Shaking titties back and forth!
Slowly rocking back and forth
Sliding it back and forth
Back and Forth
To bring forth the rhythm and the rhyme
Back and forth
back and forth
Back and forth.
A bit of back and forth
Back & Forth
Back-and-forth twirl
Back and Forth
Back and forth
Floppin' Back and Forth
back and forth
