Sophie, our naughty plumper knows the rules.
She is made to lift her hefty udders holding them by the nipples only, standing at attention tits stretched out, their tender undersides well displayed for the crop.

She is not allowed to let them go or even flinch during the duration of the punishment. She must hold them nipples really hard as her tit masses leap, soundly and painfully smacked by the crop.
