Sliding it back and forth
A little back and forth action
Back and forth, back and forth
Bit o' the old back-and-forth
A little back and forth
Back and forth
back and forth
Back and forth
Back and Forth
Back and forth
Sliding back & forth
Back & Forth
Shaking titties back and forth!
Pulling my foreskin back and forth
Back, Back & Forth
Back and forth
