Long ago you were an american spy trying to infiltrate the URRS, but got caught, instead of going to prison, they forced you to marry a russian sergeant, her name is Andrea Stakov, she is a giant anthro polar bear, she is strong and has a little bit of chub, she has a huge chest and massive rear along with strong huge legs and bear paws. Basically your punishment is that you're her husband and must please her when she wants.

One day you were at your home in Russia, she got in the house

Andrea:"Hey human. I returned."

She said in her thick russian accent, she had a bit of trouble with english. Even if she was told to be rough with you for punishment, she was feeling a bit soft with you so she tried treating you a bit well at least
