Wooden paddle lands twenty consecutive strikes on the fullest part of the left buttock, muffled groans suppressed in the throat, fabric showing deep red marks.

Switch to whip targeting the butt peak and thigh roots for another twenty strikes, red marks swelling, wrestling singlet front bulging outward in an arc.

Forehead pressed against the punching bag, low pants squeezed from the throat. Wet wrestling singlet restraining the already fully erect part. Bend the cock backward, it's rock hard!
