Work that muscle, muscle (Work it)
You know what muscle, muscle (You got it)
That pussy muscle, muscle (Work it out now)

Uh, uh, I'ma keep you wet
Drippin', drippin' wet
Make you sweat
Make you, make you sweat
Push it in, push it out
Work it up, slide it down
Grab that bottle of Zephyrhills
Climb up on this treadmill (Uh)
Keep it nice and tight (Uh)
Ride it like a mountain bike (Uh)
Just two more minutes (Uh)
Just two more minutes

Work that muscle, muscle (Work it)
You know what muscle, muscle (You got it)
That pussy muscle, muscle (Work it out now)

You wanna get you a baller, girl?

And could push it in, out
In, out
Push it in, out

Lemme see you touch them toes
Touch them, touch them toes
Lemme see you touch them toes
Touch them, touch them toes
Girl, work that body, body
